The Effect of IFRS Adoption on Investment Management : A Review of the Literature

Recent literature contains a number of studies that provide evidence that improvements in the performance related to business investments are associated with the main positive results of the implementation of international financial reporting standards (hear after IFRS). This study is an effort trying to summarize empirical evidences in current literature about the effect of the IFRS adoption on investment management. We summarize literature on the effect of IFRS a) in a European setting b) in a worldwide setting. We especially refer to the effect of European Crisis on Investment Management. We summarize evidence on the impact of IFRS adoption worldwide on investments assets, foreign direct investments (FDIs), cross boarder investments (Merger and Acquisition activities) and foreign mutual fund ownership. We finally present some evidence on the impact of IFRS adoption on US home bias and try to document the impact of IFRS adoption on international listing and IPOS in global markets.


Introduction
Financial economics theories, when they focus on the area of investment efficiency, argue that the information asymmetry between firms and outside capital providers is one of the major drivers of suboptimal capital investment.As already known by academic literature, an important goal of financial accounting information is the reduction of adverse selection costs or moral hazard issues related to information asymmetries in order to enhance capital markets efficiency.The reduction of information asymmetry is argued that could be achieved by adopting a single set of global standards, which improves the level of comparability of financial statements, and as a result the ability of investors in identifying profitable investment opportunities.Recent literature contains a number of studies suggesting that improvements in the performance related to business investments are associated with the main positive results of implementing international financial reporting standards (hear after IFRS).
Our study is an effort trying to summarize empirical evidences in current literature about the effect of the IFRS adoption on investment management.The evidence are presented by subject and then by chronological order.We summarize literature on the effect of IFRS in a European setting.We specially refer to the effect of European Crisis on Investment Management.Then we summarize research papers examining the impact of IFRS adoption in investment management worldwide.We present evidence on the impact of IFRS adoption worldwide on investments assets, foreign direct investments (FDIs), cross boarder investments (Merger and Acquisition activities) and foreign mutual fund ownership.We further present some evidence on the impact of IFRS adoption on US home bias.We finally document the impact of IFRS adoption on international listing and IPOS in global markets.The rest of the paper is organized as follows: Section 2 presents evidence on the effect of IFRS adoption on investment management in Europe; Section 3 summarises existing literature on the effect during adverse economic conditions i.e. crisis period; Section 4 presents existing literature on the Effect of IFRS adoption on investment management worldwide and Section 5 concludes.

The Impact of IFRS Adoption on Investment Management: A European Perspective
There is extensive literature examining the general issue of the economic consequences of mandated changes of accounting standards worldwide.There is also, the stream of research exploring the economic consequences of the mandatory adoption of IFRS especially in Europe 1 .We present evidence of prior literature relating the consequences of IFRS mandatory adoption and investment decisions.We start by presenting evidence under a European setting.The key points, research questions, sample and main findings of these studies are summarized in Table 1.
L. M.-Ramos (2008) [1] presented empirical evidence "that the accounting harmonization process in Europe is a way to reduce information costs and unfamiliarity between countries and, therefore, an important way of encouraging international trade and foreign direct investments (FDIs)".He provided, from a macroeconomic perspective, empirical findings on the IFRS adoption effect in Europe, (as is shown in Table 1).After the establishment of accounting harmonization, there is a reduction in information costs and risks of conducting busi- As of 2005, it is required by firms listed in countries of the European Union (EU) to prepare their consolidated financial statements based on the requirements of the International Financial Reporting Standards (IFRS).Technology and Investment ness with unfamiliar partners and "companies in different countries are expected to participate in foreign activities to a greater extent".Furthermore, this study also examined the adoption of IFRS considering uncertainty aversion diversity in countries and provided evidence that "uncertainty-averse countries benefit the most from IFRS adoption in terms of FDI, since the improvement of accounting information, in turn, fosters financial transparency and comparability, and reduces information asymmetries and unfamiliarity among agents in different countries".In brief, this means that harmonization of high quality accounting standards can be regarded as a strategy to reduce the perceived risks of investing abroad and to foster trade and FDI.
T. Schleicher, A. Tahoun and M. Walker (2010) [2] focused on an outcome of IFRS adoption rather than expected outcomes in the countries of the European Union (EU).They examined regarding investment efficiency, "which types of firms within which types of economies benefited most from IFRS adoption".
They also explored the economic consequences related to the mandatory adoption of IFRS in EU countries by presenting the types of economies having the largest reduction in sensitivity of investment-cash flow during post-IFRS adoption period.They also explored "whether the reduction in investment cash flow sensitivity depends on firm size as well as economy type".Furthermore, their study relates to the research examining the relationship between financial market development and economic growth.Economic growth is facilitated by developed financial markets.Overall, the results of this study suggested that IFRS adoption may "have improved the functioning of capital markets in relation to small firms in insider economies" and that investment cash flow sensitivity is lower in outsider economies than that of insider economies, (as is shown in Table 1).
Considering that IFRS adoption is related with higher accounting quality and that the higher-quality financial reporting fosters efficient firm investment, they examined the real business effects of applying IFRS in terms of firms' investment efficiency.They found that IFRS accounting is associated with a lower degree of overinvestment.They also documented that enforcement plays a positively significant role on the impact of the IFRS adoption on the financial reporting system and as a result on the firms' investment efficiency.Overall S. Lenger, J.
Ernstberger and J. Stiebale (2011) [3], demonstrated that IFRS adoption is positively associated with higher accounting quality, which fosters efficient firm investment (as is shown in Table 1).Finally, this study contributed to recent empirical research with the results that IFRS has real business effects, especially for public firms.Also, IFRS accounting is associated with a higher degree of investment efficiency, and in general IFRS influences capital market properties.P. André, A. Filip and S. Marmousez (2014) [4] examined the relationship between conservatism, which can be considered one of the dimensions of finan-Technology and Investment cial reporting quality, and investment efficiency using dataset of French firms before and after the mandatory adoption of IFRS in 2005.The objective of this research is to test whether conservatism, an important quality factor of financial reporting, is associated with greater investment efficiency, or in other words with lower over-or under-investment, before and after the mandatory application of IFRS in 2005.
C. Chen, D. Young, and Z. Zhuang (2013) [5], examined the externalities of mandatory IFRS adoption on the investment efficiency of firms from 17 European countries.They investigating the spillover effects of a firm's ROA difference versus its foreign peers and improved disclosure of foreign peers on the firm's investment efficiency.They supported with their results that after IFRS adoption, the spillover effect of the firm's ROA difference in comparison to its foreign peers on reducing the firm's under-or overinvestment is increased (as is shown in Table 1).In addition, it is provided that the improved disclosure by a firm's foreign peers under IFRS also has a spillover effect on reducing the firm's under-or overinvestment.Furthermore, they also found that investment Huang, and Y. Li, (2014) [6], conjectured that productivity may improve after mandatory IFRS adoption due to lower information asymmetry, easier access to equity financing, better contracting mechanisms, and increased comparability, (as is shown in Table 1).Their empirical results also indicated "that the production efficiency of mandatory IFRS adopters increases significantly after mandatory adoption".They further documented that in countries with large GAAP differences, in the post IFRS adoption period production efficiency is further improved, stock return volatility is reduced and analyst forecast dispersion is also decreased and the number of comparable industry peers is significantly increased.Overall, the total evidence suggested that firms with significant improvements in their information reporting environment from mandatory IFRS adoption are able to increase productivity substantially.
Firm production efficiency increases more for those firms that have reduced information asymmetry and increased comparability after the adoption, since financial statement transparency facilitates also equity financing, compensation contracting, and decision-making.
As extensively referred accounting harmonisation has positive effect on firm productivity but also to other economic dimensions.Improving accounting standards harmonisation worldwide has as consequence the reduction of the perceived risks of investing abroad.The IFRS adoption reduces information costs among countries, gives more opportunities for international trade in goods and investments and concurrently improving financial reporting quality fosters trade and FDIs.Specifically, the accounting harmonisation process in Europe intends to reduce information costs and unfamiliarity between European countries so as to improve international trade and foreign direct investments.
Considering heterogeneity issues among the European Union countries of and their uncertainty aversion diversity, L. M.-Ramos (2011) [7], studies this accounting harmonisation process in Europe.This study provided evidence that transition economies gained the most benefit from IFRS adoption regarding trade in goods in the period following 1999 (as is shown in Table 1).In addition to that there are countries that gained the most benefit from the IFRS adoption regarding trade in goods due to the fact that IFRS have different implementation and interpretation in countries with different legal systems.Moreover, L.
M.-Ramos (2011) [7], provided evidence that "uncertainty-averse countries benefit the most from IFRS adoption in terms of FDI" and that the "information asymmetries between neighbouring countries and countries sharing recent colo-Technology and Investment • Examine the relationship between conservatism, a dimension of financial reporting quality, and investment efficiency.• Test whether a higher degree of conservatism, and of financial reporting, is associated with a greater investment efficiency, or with lower over-or under-investment.

nial links are less pronounced prior to IFRS adoption and, therefore, the benefits of IFRS adoption are lower".Finally, L. M.-Ramos (2011) [7] proposed that there is a need for further research due to diversity in the implementation process of mandatory IFRS adoption in European countries in the accounting harmonisation process, and in the dominant reporting choice among listed firms before 2005 which had significant consequences regarding trade in goods and FDI.
To summarize: IFRS adoption in Europe improved accounting harmonization, fostered international trade and foreign direct investments (FDIs) by reducing information asymmetry, information cost, unfamiliarity between countries and improving transparency and comparability (L M-Rammos (2008) [1]).IFRS adoption in European Union had positive effects on investment efficiency, especially for large firms and outsider economies, where investment cash flow sensitivity is lower than inside economies (T.Schleicher, A. Tahoun and M. Walker (2010) [2]).IFRS adoption also is positively associated with higher accounting quality, which fosters efficient firms' investment, lowers overinvestment and positively influences capital markets (S.Lenger, J. Ernstberger, J Stiebale (2011) [3]).Mandatory IFRS adoption significantly increases production efficiency, which in turn reduces stock return volatility and the number of comparable industry peers is significantly decreased.Firm production efficiency is more enhanced for IFRS adopters (R. D. Banker, R. Huang, Y. Li (2014) [5]).Accounting harmonization process in Europe had significant positive effects in trade of goods but the heterogeneity among European countries in terms of implementation process needs to be explored by further research (L.M-Rammos (2011) [6]).

The Effect of European Crisis on Investment Management
Additional to the extensive literature of European accounting harmonization with IFRS adoption, there is also a stream of literature exploring the economic effects of the recent European crisis.The European debt crisis and especially "the Eurozone crisis is a debt crisis that has been taking place in the European Union".It is well accepted that the crisis was merely apparent during the period 2008-2010.However, even still several Eurozone member states (Greece, Portugal etc.) are in national supervision or recession, since after the crisis they "were unable to repay or refinance their government debt or to bail out over indebted banks under their national supervision without the assistance of third parties like other Eurozone countries, the European Central Bank (ECB), or the International Monetary Fund (IMF)".We present a number of studies that have explored the effects of the crisis in the investment performance of firms.The key points; authors, research questions, sample and main findings of these studies are presented in brief in Table 2.
M. Campello, E. Giambona, J. R. Graham and C. R. Harvey (2012) [8] reported that "the recent crisis did not severely hinder firms' ability to access lines of credit and draw down existing facilities".This proved to be of utmost importance for European companies as credit lines from banking sector became an essential way of financing and eased the financial crisis effect on investment and firm's financial performance, (as is shown Table 2).Additionally, S. L. Boumediene, O. Nafti and E. Boumediene (2014) [9] studied the impact of the economic crisis on the informational content of accounting information based on the IFRS financial reporting system adopted by France.They examined the correlation relationship between discretionary accruals and accounting and financial in France before and after the crisis.They found that before the crisis the IFRS adoption "affects negatively the relationship between the yield of the French listed companies and the proportion of assets turnover" (as is shown Table 2).They further report that "for the period after the crisis, the results show that French listed firms did not enter into new long-term investment process, but are more interested in increasing their turnover and keeping their customers".They proposed that future research can include more European Union (EU) countries to examine the effect of IFRS adoption during the 2008 crisis on the relationship between yield and accounting variables.
H. Balfoussia and H. D. Gibson (2016) [10], examined the association between overall financial conditions and corporate investment in countries of the euro area.Furthermore, they examined whether the well-documented investmentcash flow sensitivity arising from the external financing premium of constrained firms varies over time and with overall financial conditions.Their results suggested that "financial conditions have indeed played a significant role in corporate investment decisions over recent years, rendering financing constraints even more binding", (as is shown • Explore whether the sensitivity of firm-level investment to cash-flow, typically associated with an external financing premium, is time-varying and in particular whether it varies with overall financial conditions.

• Financial conditions have indeed played a significant role in corporate investment decisions over recent years, rendering financing constraints even more binding.• The impact of credit conditions is not uniform across firms, but rather it varies depending on firm size and leverage, with constrained firms being substantially more likely to condition their investment decisions on overall credit conditions.

• Sample of 220 firm year observations on the French stock market and periods 2006-2007 and 2009-2011.
• The 2008 financial crisis contributed to reducing the information content of accounting numbers due to lack of confidence created by investors towards the information published on the basis of international standards.
Campello, Giambona, Graham, and Harvey (2012) [8] • examine how firms in Europe used credit lines during the financial crisis.
• the crisis period the cost of equity capital was increased for voluntary and mandatory IFRS adopters and that investment strategy for both groups seems to remains sustainable even under adverse economic conditions, (as is shown Table 2).
To summarize: Even during financial crisis, European companies continued to have credit lines from the banking sector financing their investments and maintaining their financial performance M. Campello, E. Giambona, J. R. Graham and C. R. Harvey (2012) [8]).French listed firms during crisis were interested in keeping their customers and increasing their assets turnover, than participating in new long term investment projects (S.L. Boumediene, O. Nafti and E. Boumediene (2014) [9]).During financial crisis the effect of credit conditions varies among firms depending on firm size leverage.Additionally, financial constrained firms are more likely to condition their investment decisions on overall credit conditions (H.Balfoussia and H. D. Gibson (2016) [10]).During the crisis period the cost of equity capital was increased for voluntary and mandatory IFRS adopters and the investment strategy of both groups seemed to pertain even under adverse economic conditions (L.Doukakis, K. Kapellas and G. Siougle (2017) [11]).

The Effect of IFRS Adoption on Investment Management Worldwide
International financial reporting standards (IFRS) have been also adopted by countries outside the European Union for financial reporting purposes.The adoption of IFRS may improve the informational environment if the change from local GAAP (Generally Accepted Accounting Principals) to IFRS brings higher quality financial reporting and lower information asymmetries among countries.Therefore, a question arises whether the adoption of IFRS results in worldwide economic benefits.We present evidence from studies using extended international samples.The key points and main findings of these studies are briefly presented in Table 3.
A. Florou and P. F. Pope (2012) [12], examined "whether the mandatory introduction of IFRS leads to an increase in institutional investor demand for equities" and they found that "institutional holdings increase for mandatory IFRS adopters".The IFRS adoption leading to higher financial reporting quality, has significant benefits on institutional holdings, (as is shown in Table 3).This study also showed that "increased institutional holdings are concentrated in countries where enforcement and reporting incentives are strongest and where the differences between local GAAP and IFRS are relatively high".
Prior relevant academic research suggested that information asymmetry be- For this purpose, one of the goals of the adoption of IFRS is to establish a high quality, worldwide familiar set of accounting standards.Following this and based on the familiarity of IFRS, D. Amiram (2012) [13] predicted that foreign investments will increase in countries that adopted IFRS after the transition to IFRS.He investigated the relationship between IFRS adoption and foreign investment decisions and found that foreign equity portfolio investments (FPI) show an increase in IFRS adopting countries, (as is shown in Table 3).More importantly, he found that "this relation is driven by foreign investors from countries that also use IFRS".
Furthermore, a primary motivation for creating IFRS was to increase capital examined whether IFRS enhances firm-level capital investment efficiency.Specifically, they examined the mandatory IFRS adoption effect on the economic fundamental of firms' capital investment decisions and if there is an improvement in firm level capital investment efficiency using data from 26 countries.
They focused on the examination of the associations between IFRS adoptions and two measures of firm-level capital investment efficiency: "investment-cash flow sensitivity and value-enhancing risk taking".The former is a classic measure of investment efficiency in the corporate finance literature.They also investigated the differential effect of investment efficiency associated with the countries' legal and political environment as well as the financial transparency and ownership concentration after the mandatory IFRS adoption.They found that "firms' investment policy is associated with a shift towards a risk-adjusted optimal level while their investment-cash flow sensitivity decreases" and "this association is more pronounced in countries with weak law enforcement institutions and higher ownership concentration".Finally, they concluded that the increased financial disclosure and financial statements comparability, after the IFRS adoption benefit outside capital providers and thus lead to improved investment efficiency at the firm-level, which is globally an issue of high importance to firm managers and regulators, (as is shown in Table 3).
H. Louis and O. Urcan (2014) [15] examined "whether the mandatory adoption of IFRS leads to an increase in cross-border acquisitions into the adopting countries and whether there is any effect by concurrent enforcement changes".
They found that after IFRS adoption there is a significant increase in the odds of a cross-border acquisition for a listed firm in the adopting countries, whereas for Technology and Investment an unlisted firm the change in the odds is insignificantly different from zero,, (as is shown in Table 3).Additionally, their findings supported that the increase in the flow of "investment into the IFRS adopting countries comes from both non-IFRS adopting countries and other IFRS adopting countries" and "that the mandatory adoption of IFRS leads to a substantial increase in cross-border acquisitions of listed companied in the adopting countries".
IFRS introduction has been the largest reporting standards change in accounting history since a continuous large number of countries move to this trend.Mandatory reporting under IFRS has been examined extensively but of utmost significance to researchers, policy makers, and regulators has been also a better understanding of the sources that led to the observed capital market benefits.A number of these benefits presented in current literature are related to improvements in foreign (cross-border) investments, favorable liquidity effects and a reduction in the cost of equity capital, which eventually results in improvements in investment returns and efficiency.The debate on mandatory accounting harmonization is an open issue.
On the one hand mandatory regulatory intervention yield key benefits based on the argument that accounting quality is determined by accounting standards.
The international comparability of financial statements should improve through the adoption of a common accounting "language".This should ease cross-border capital flows and hence reduce the cost of capital.On the other hand, the quality of financial reporting is more affected by preparers' incentives and institutional context than by accounting standards.Even in the same country, there are differences between firms regarding the extent of reliance on external funding and their cost of compliance with financial disclose requirements.Companies that have little to gain from IFRS may decide to make use of any embedded flexibility in IFRS implementation.Academic research also showed some evidence that the voluntary adoption of IFRS reduces the cost of equity capital, but the results of the empirical research about the economic consequences of mandatory adoption remain unclear.
U. Brüggemann, H. Daske, C. Homburg and P. F. Pope (2012) [16], analyzed the effect of global IFRS adoption on cross-border equity investment by individual investors.Individual investors tend to be less sophisticated than their institutional peers.This study predicted that individual investors focus on those stocks within the IFRS.Following these assertions individual investors are expected to ignore the complex interaction between IFRS adoption and the institutional stock environment.The empirical results of their study suggested "that stocks experience a significant increase in Open Market trading volume following mandatory adoption of IFRS" and that "global IFRS adoption enhances cross-border equity investments by individual investors", (as is shown in Table 3).
High uniformity in accounting standards imposes less information cost on foreign acquirers and enables them to better value target firms and monitor for-  [17], investigated whether differences in accounting standards across countries restrain firms from investing in foreign markets.They provided evidence "that the volume of M & A activity across country pairs is larger for pairs of countries with similar GAAP", and "that the takeover premium is higher if target countries' GAAP is similar to that of the acquiring firm's country" (as is shown in Table 3).They further demonstrated that mandatory IFRS adoption "attracted more cross-border M & As among IFRS adopting countries, and that this increase in M & A activity within the IFRS countries is more pronounced for country pairs with low degree of similarity in GAAP in the pre-IFRS adoption period".
Following the intuition that comparability of financial statements is among the most important issues for global investors, M. DeFond, X. Hu, M. Hung and S. Li (2011) [18], examined the effect of adopting a uniform set of accounting standards like the mandatory IFRS adoption on comparability and cross-border investment.They investigated the change in foreign mutual fund investment for firms that started using IFRS after its mandatory adoption in the European Union (EU) in 2005.Empirical evidence of this study suggested that mandatory adoption of IFRS increased more foreign investment among companies in countries with strong implementation credibility and significant advances in uniformity.Furthermore, according to additional analysis the enhanced comparability associated with mandatory IFRS adoption does not increase domestic mutual fund ownership as domestic investors are more familiar with local accounting standards,, (as is shown in Table 3).They also identified that "the increase in foreign mutual fund ownership in response to improved comparability is primarily driven by foreign global mutual funds".
M. DeFond, X. Hu, M. Hung and S. Li (2011) [18] complement and extend prior relevant literature by investigating whether the role of uniformity leads to improved financial statement comparability.The change in the financial reporting environment after a country's adoption of IFRS is likely to increase the transparency of financial reports and lead businesses and individuals in other countries to invest in the adopting country.
L. A. Gordon, M. P. Loeb and W. Zhu (2012) [19] investigated the impact of IFRS adoption on the overall country FDI inflows and whether this impact varies for developing or developed economies.They provided evidence that there exists a positive association between overall FDI inflows and a country's IFRS adoption (as is shown in Table 3).These results are more significant for countries characterized as developing economies rather than for those countries characterized as developed economies.Furthermore, they identified the country's desire to receive financial support from the World Bank as another incentive for IFRS adoption by countries with developing economies.Overall, L.A. Gordon, M. P.
Loeb and W. Zhu (2012) [19] provided evidence into clarifying the relationship Technology and Investment a) between overall FDI inflows and the country's accounting standards and b) between the ability of a country characterized as developing economy to receive loans from international organizations like the World Bank and the accounting standards used by that country.They proposed that future research should examine the above issues as countries become more experienced with the use of IFRS.
C. P. Chen, Y. Ding and B. Xu (2014) [20] examined the relationship between FDI activities and convergence of accounting standards and tested the effect of IFRS adoption on changes in FDI flows between countries.Cross-border investments are promoted by the adoption of a set of common financial reporting standards by reducing the information barrier to FDI.They found a positive association between FDI flows and conformity to IFRS, which is stronger for country pairs with greater institutional differences, (as is shown in Table 3).
This study also showed that "accounting information is relevant to FDI decisions and the adoption of IFRS is not just a change of label, but a more profound mutation that fosters lower transaction costs and better transparency".
Trying to verify that the IFRS adoption promised a greater cross-border investment and as a consequence a more efficient capital allocation, G. Lee and N.
Fargher (2010) [21], investigated whether the mandated adoption of IFRS brings potential benefits to investors.Specifically, they examined the effect of the IFRS adoption on the international diversification of Australian investors and provided evidence that the mandatory IFRS adoption encouraged greater foreign investment for investors.This study supported that investors are benefited from the IFRS adoption, which is associated with greater cross-border equity investments, increase in the comparability of financial reports among capital markets and information asymmetry reduction (as is shown in Table 3).They proposed for future research the examination of the IFRS adoption impact on the usefulness of financial statements to other users except investors, such as credit analysts, equity analysts, debt holders and internal managers.
I. K. Khurana and P. N. Michas (2011) [22], investigated whether mandatory IFRS adoption at the country level reduces US investors' bias against investments in foreign countries, since investors tend "to overweight domestic stocks in their common stock portfolios".They provided evidence that US home bias is lower for countries that mandate IFRS adoption, (as is shown in Table 3).Particularly, they found that the reduction in the US home bias following the mandatory IFRS adoption is greater "for countries with larger differences between IFRS and their domestic accounting standards", "for countries with a stricter rule of law, a common law legal origin" and "in countries with greater incentives to report high-quality financial information".This bias reduction is not driven by the EU countries.Additionally, the authors provided empirical evidence "that a common set of global accounting standards matter for portfolio holdings of US investors" as they consider the enforcement of standards to be an important factor for making investments outside the US.Technology and Investment The recent global trend towards the use of IFRS signals reduction of information asymmetries for international investors.A stronger regulatory environment should accompany these standards so as to gain legitimacy.The legal standards system and the enforcement regime are significant for the establishment of accounting standards, which are important for US investors making portfolio allocations in foreign equities.
K. M. Shima and E. A. Gordon (2011) [23], investigated whether there exist an association between a country's use of IFRS and increased US investment in foreign equities.They found a positive association between US investment and IFRS adoption "only when it is combined with a strong regulatory environment, specifically a strong enforcement regime", (as is shown in Table 3).They determined two dimensions of the regulatory environment, legal standards system and enforcement regime and concluded that "both factors individually and when interacted with IFRS are associated with US foreign investment".
H. A. Hong, M. Hung and G. J. Lobo (2014) [24] examined the consequences of the mandatory IFRS adoption for IPOs.Particularly, they examined the impact of mandatory IFRS adoption on IPO underpricing and capital source in global markets.Their results supported the existence of a statistically and economically significant a) "reduction in IPO underpricing following mandatory IFRS adoption" and b) "increase in the amount of capital raised from foreign markets".They also found that the above relations are higher for firms in countries experiencing large accounting changes and are more evident among firms in countries with strong implementation credibility (as is shown in Table 3).
Thus they supported that the effect of IFRS adoption depends on country-level institutions, accounting differences, and implementation credibility.Furthermore, regarding the effect of mandatory IFRS adoption on IPO underpricing for domestic and global IPOs, it is noted that the decrease in underpricing for global IPOs is more pronounced than it is for domestic IPOs, since foreign investors face greater information asymmetry than domestic investors, and thus benefit more from improved financial reporting.
Differences in disclosure requirements and financial reporting standards across countries create information barriers that create obstacles to cross-border capital flows and investments.Cross-listings are important as they ease crossborder capital flows and promote the integration of global financial markets.
The adoption of a single set of global high-quality accounting standards could reduce cross-border accounting information and regulatory barriers, thereby facilitating cross-border investment.
An increasing body of literature examining the economic consequences of mandatory IFRS adoption has raised the question of whether this adoption facilitates firms' cross-border stock-listing activities.L. Chen, J. Ng and A. Tsang evidence that the effect of mandatory IFRS adoption on a firm's cross-listing activities varies "with the institutional characteristics of the firm's home country".
In particular, they found that mandatory IFRS-adopters compared to non-IFRS adopters, experience a larger increase in the likelihood to cross-list, as well as a larger increase in the number of cross-listing target countries after mandatory IFRS adoption (as is shown in Table 3).Moreover, L. Chen, J. Ng and A. Tsang (2015) [25], noticed, as in most studies that exploit an exogenous event, that it is hard to examine the effect of mandatory IFRS adoption on cross-listings unambiguously and causally attribute the observed effects to the event of interest.For example, the EU countries have initiated several directives aimed at integrating the European capital markets, including IFRS, to facilitate cross-listings of EU firms, and these initiatives occur at the same time of the mandatory IFRS adoption.This means that additional academic research is required on the economic consequences of mandatory IFRS adoption to explore the question whether it facilitates firms' cross-border stock-listing activities, so as to be able to provide more confident empirical results.
To summarize: Mandatory IFRS adoption increased the institutional investors demand for equities and additionally more for countries with strong legal enforcement environment and high reporting incentives (A.Florou and P. F. Pope (2012) [12]).Foreign equity portfolio investments (FDIs) increased due to the increase of familiarity and reduction of asymmetry (D.Amiran (2012) [13]).Homburg and P. F. Pope (2012) [16]).The volume of M & A activity across country pairs is larger for pairs of countries with high uniformity in accounting standards, which imposes less information cost on foreign acquirers.This increase in M & A activity within the IFRS countries is more evident when there is low uniformity in accounting standards in the pre-IFRS adoption period (J.R.

IFRS adoption enhances firm
Francis, S. Χ. Huang and I. Κ. Khurana (2012) [17]).IFRS adoption is positively associated with overall country' FDI inflows.This positive association is more significant in countries with developing economies (L. A. Gordon, M. P. Loeb and W. Zhu (2012) [19]).IFRS adoption across countries leads to convergence of accounting standards which in turn improves familiarity, transparency, reduces transaction cost and as a result enhances FDI flows between countries (C. P. Chen, Y. Ding and B. Xu (2014) [20]).Mandatory IFRS adoption encouraged • Stocks experience a significant increase in Open Market trading volume following adoption of IFRS.• Global IFRS adoption enhances cross-border equity investments by individual investors.However, this effect does not materialize equally across stocks due individual investors' limited attention.• Individual investors ignore the complex interaction between IFRS adoption and the institutional environment of the stocks, because they tend to be less sophisticated than their institutional peers and they predict that individual investors focus on those stocks within the IFRS-enhanced choice set that catch their attention, for example, through increased media coverage.

Louis and Urcan (2014) [15] • Examine whether the 2005 mandatory adoption of IFRS leads to an increase in cross-border acquisitions into the adopting countries and whether any documented effect is driven by concurrent enforcement changes.
• Sample of completed acquisitions 885 of listed firms from the adopting countries and 2285 acquisitions of unlisted companies from 2000 to 2010.
• Mandatory IFRS adoption substantially increases cross-border acquisitions of listed companied in the adopting countries.• IFRS adoption increase significantly the odds of a cross-border acquisition of a listed firm in the adopting countries.• The increase in the flow of investment into the IFRS adopting countries comes from both non-IFRS adopting countries and other IFRS adopting countries.

foreign investment, meaning greater cross-border investments and as a consequence a more efficient capital allocation (G. Lee and N. Fargher (2010) [21]).
US investors are less home biased against investments in foreign countries that mandate IFRS adoption.This reduction in the US home bias following the mandatory IFRS adoption is greater for countries with significantly different local standards in the pre IFRS adoption period (I.K. Khurana and P. N. Michas (2011) [22]).There is a significantly positive association between a country's use of IFRS and increased US investment in foreign equities a strong regulatory environment (K.M. Shima and E. A. Gordon (2011) [23]).There is a positive impact of mandatory IFRS adoption on IPO underpricing and capital source in global markets.This reduction in IPO underpricing is higher for firms in countries experiencing large accounting changes and are more evident among firms in countries with strong implementation credibility.Mandatory IFRS adoption reduces more underpricing for global IPOs than domestic IPOs, since foreign investors face greater information asymmetry than domestic investors, and thus benefit more from improved financial reporting (H. A. Hong, M. Hung and G. J. Lobo (2014) [24]).Mandatory IFRS adoption has positive effects on firms' cross-listing activities but it also depends on the institutional characteristics in each country.However exogenous events which happen concurrently should be incorporated in the examination of the effects of IFRS adoption for better evaluation (L.Chen, J. Ng and A. Tsang (2015) [25]).

Conclusions
We presented existing literature on the effects of IFRS adoption on investment management, firstly under a European setting and more explicitly during the recent European crisis and secondly under a worldwide setting.Significant research efforts support that accounting harmonization in Europe is an important way to reduce the perceived risks so as to enhance international trade, foreign direct investments (FDIs), cross-border investments (Merger and Acquisition activities), and foreign mutual fund ownership.Productivity efficiency also seems to be improved after IFRS adoption.Of course, it has to be noticed that In terms of European crisis there are various conclusions but in general firms are trying to maintain their performance.Financial constraints are important during the crisis period to interpret the interaction of IFRS adoption and investment management.
IFRS adoption is considered to be positively associated with investment efficiency.Nevertheless, there is also a need for additional research effort so as to identify other parameters and indicators which could affect investment efficiency and apply concurrently within the continuous ongoing changes of the rapidly developing international financial reporting standards.Future research could incorporate macroeconomic factors, the implementation process of IFRS adoption among countries, the level of experience using IFRS, to better understand and evaluate the economic consequences of accounting harmonization.Additionally, different capital market conditions, regulations and institutional characteristics among IFRS adopting countries may be investigated having an impact on investment management.
changes induced by greater disclosure by foreign peers under IFRS are value relevant.Overall, C. Chen, D. Young, and Z. Zhuang (2013)[5], contributed to the literature supporting the positive externalities of IFRS regulation on firms' investment efficiency, with additional findings that legal enforcement strength, composition of peer firms, and industry competition environments affect significantly the spillover effects.Productivity is the efficiency in production and is measured by how much output is obtained from a given set of inputs.Academic literature has presented long research effort focusing on measuring productivity and addressing productivity differences across businesses.Some studies associate productivity with firm-specific internal drivers such as managerial talent, quality of capital inputs and general labor, R & D investment and information technology, product innovation and firm structure decisions and some other studies with external drivers such as technology spillovers, competition, flexible input markets, and deregulation.It is considered that the quality of accounting standards as an infrastructure of financial markets, and the resulting financial reporting can impact productivity through project identification, but there is limited evidence on how changes in financial reporting regimes and accounting standards may affect productivity.IFRS adoption has many positive effects like it leads to increased disclosure and transparency, which means lower information asymmetry and easier access to equity financing, and improves the efficiency of contracting between firms and managers, which means impelling managers to take action in the best interests of shareholders.Summarizing and going forward, IFRS adoption increasing comparability and transparency, may lead to increased shareholding by institutional investors and foreign mutual funds, more efficient relative performance evaluation, and increased product market competition.Therefore, based on the previous reasoning, R. D. Banker, R. Huang and Y. Li Technology and Investment (2014)[6] investigated the association between productivity improvement and changes in accounting standards and support that firm productivity improves after mandatory adoption of IFRS.They studied the association between productivity and accounting standard quality in the framework of mandatory IFRS adoption.They used revenue as the output measure and cost of inventory, general and administrative expenses, fixed assets, past R & D expenditures, and intangible assets as input measures of production efficiency.R.

investment efficiency as elucidated by the International Accounting Standards Board Chairman David Tweedie: "As the world's capital markets integrate, the logic of a single set of accounting standards is evident.A single set of international standards … should make the allocation of capital … more efficient" [emphasis added] (Tweedie 2006).Focusing directly on the realization of this benefit, G. C. Biddle, C. M. Callahan, H. Hong, and R. L. Knowles (2011, March 1, 2013, August 31, 2015) [14],

Biddle, C. M. Callahan, H. Hong, and R. L. Knowles (2011, March 1, 2013, August 31, 2015) [14]).Mandatory IFRS adoption leads to an increase in cross-border acquisitions, positively affected by the legal enforcement environment (H. Louis and O. Urcan (2014) [15]).Global IFRS adoption positively enhanced crossborder equity investments by individual investors (U.Brüggemann, H. Daske, C.
legal enforcement significantly contributes to the positive association between IFRS adoption on investment management.Academic research results based on worldwide evidence, about the effects of IFRS adoption on investment management, identify a mitigation of investors' unfamiliarity of foreign markets and information asymmetry, which enhance foreign equity portfolio investments, cross border acquisitions, foreign mutual fund investment, domestic and global IPOs and thus improve investment efficiency.Research limitations are not ignored by existing literature and could be summarized as differences in: characteristics of IFRS adoption and implementation process across countries; economies; regulations and capital markets development, thereby making it difficult to identify the causality effect and interpret the K. Kapellas, G.
