ABSTRACT

We address the effect of the effect of benchmark effect of industry prominent firm for the influence of the duopoly competition. Consumers always consider prominent firms as the industry benchmark, when they evaluate other firms’ product, treating prominent firm as a reference point, thus show the loss aversion behavior. We find that benchmarking effect of the prominent firm makes consumer surplus increase, while decreases both firms’ profits.

1. Introduction

When consumers choose brand, they tend to focus on the prominent brand, and treat the prominent firm as reference point. Facing those little-known brands, consumers compare them with prominent firm, that is to say, these well-known brand have a benchmark effect. The prominent firm is probably the first firm to enter the industry, thus can be recognized by consumers earliest, it may also can be the most famous firm in the industry that through marketing and other means. This is illustrated within a duopoly frame by Zhou J. [1] when consumers facing the choice between the prominent firm with its rival, benchmark effect from prominent firm will affect duopoly competition.

Overall, we build on the work of Zhou, J. and Karle and Peitz [5] , based on empirical evidence of loss aversion on service quality and price [6] and develop a parsimonious model that allows firms to make price and quality decisions in the context of a consumer behavior model when market exits a prominent firm.

The rest of this paper is organized as follows. Section 2 presents the model that is analyzed in Section 3, Section 4 presents the conclusions. All omitted proofs are included in Appendix.

2. The Model Setup

We use Hotelling framework (Hotelling) [7] and assume that the market consists of two firms, A and B, each supplying a single distinct brand at a constant unit cost that we normalize to zero. Firm A’s located at the endpoint 0, and firm 2’s is at the other endpoint 1. Firm A is the prominent firm, t is the transportation costs. Firm A provide goods A with price PA, quality SA, Firm B provide good B with price PB, quality SB. There is α proportion consumers treat firm A as reference point. Their quality cost is.

To determine the market demand that the two firms face, let the non-loss-averse consumer type in [0, 1], who won’t regard firm A to their reference point, they are indifferent between buying good A and good B. be denoted by X, correspondingly, the indifferent, loss-averse consumer is denoted by.

1) Consumers utility function:

For those non-loss-averse consumers: utility is a standard hoteling model.

For those loss averse consumers: utility = intrinsic utility + psychological utility

Psychologicalutility dependent on the gap between the firm’s offer and the benchmark.

V: reservation value; θ: service factor; λ: the weight of loss (λ > 1).

So, there will are 4 case:

Case 1; Case 2.

Case 3; Case 4.

2) The profit of firms

3. Analysis

Because it is a multistage game, we use the concept of subgame perfect equilibrium and analyze the decisions of firms and consumers in the reverse order to solve for equilibrium in prices and qualitys. We first focus on, which provides us the benchmark against which our results are compared.

3.1. None Loss Aversion Behavior Consumers (α = 0)

We get an equilibrium solution:

3.2. Exit Loss Averse Consumers (α > 0)

・ For case 1, 2, 3, we get an equilibrium solution, and case 4 have not an equilibrium solution:

Proposition 1. There exists three Nash Equilibriums, ,;,

; in addition, , ,;, , , , , , , , ,

Interpretation: There is no prominent advantage for the prominent firm A. Firm A and firm B make the same service and price decisions, and thus gain the same profits. Firm B, the competitor will follow just his decisions so as to prevent possible utility loss, without additional technology investment/cost.

Proposition 2., , , When,; When, ,.

Interpretation: And there is a threshold, where the case 3 can be the better equilibrium than case 1.

Proposition 2.,

Interpretation: loss aversion reduces firm profits and lowers service/product quality as well as prices offered, and increase consumer surplus.

4. Conclusions

We study competition on price and quality strategies in markets under benchmark effects of prominent firm. Benchmark is modeled as loss aversion. Consumers form the reference point facing the other firm’s goods. We show that the benchmark effects make both firms perform the same, both firms still make the same price/quality decisions, and their profits are the same. The prominent firm can’t benefit from the benchmark effect. Since the other firm has motivation to decrease the gap between them. Furthermore, loss aversion has negative impacts in both firms’ profit; however, it benefits consumers most of the time.

Because under our setting is that the cost of two firm is the same, so, it will be different when their margin quality cost is asymmetric, it is my next work.
