Experimental Economics

This is the first comprehensive treatment of laboratory experiments designed to evaluate economic propositions under carefully controlled conditions. While it acknowledges that laboratory experiments are no panacea, it argues cogently for their effectiveness in selected situations. Covering methodological and procedural issues as well as theory, Experimental Economics is not only a textbook but also a useful introduction to laboratory methods for professional economists. The emphasis is on organizing and evaluating existing results. The book can be used as an anchoring device for a course at either the graduate or advanced undergraduate level. Applications include financial market experiments, oligopoly price competition, auctions, bargaining, provision of public goods, experimental games, and decision making under uncertainty. The book also contains instructions for a variety of laboratory experiments.laboratory experiments, financial markets, price competition, auctions, bargaining, games, decision making, uncertainty

Markets with bilateral bargaining and incomplete information

We study the relationship between bargaining and competition with incomplete information. We consider a model with two uninformed and identical buyers and two sellers. One of the sellers has a privately-known reservation price, which can either be Low or High. The other seller’s reservation price is commonly known to be in between the Low and High values of the privately-informed seller. Buyers move in sequence, and make offers with the second buyer observing the offer made by the first buyer. The sellers respond simultaneously. We show that there are two types of (perfect Bayes) equilibrium. In one equilibrium, the buyer who moves second does better. In the second equilibrium, buyers’ expected payoffs are equalised, and the price received by the seller with the known reservation value is determined entirely by the equuilibrium of the two-player game between a single buyer and an informed seller. We also discuss extensions of the model to multiple buyers and sellers, and to the case where both sellers are privately informed

Strategic factor markets: Bargaining, scarcity, and resource complementarity

Strategic factor market theory suggests that without luck or asymmetric expectations, firms can't appropriate gains from acquired resources. Adopting the bargaining perspective on resource advantage, we hold that this is only true in the absence of resource complementarity. We extend factor market theory to account for resource complementarity, and we show that firms can profit when they exhibit superior complementarity to target resources, even in the absence of asymmetric expectations. Thus we provide an alternative interpretation of managers' recent emphasis on externally acquired resources.Complementarity; bargain perspective; value appropriation; resource acquisition; asymmetric expectation;

Markov Equilibria in Dynamic Matching and Bargaining Games

Rubinstein and Wolinsky (1990) show that a simple homogeneous market with exogenous matching has continuum of (non-competitive) perfect equilibria, but the unique Markov perfect equilibrium is competitive. By contrast, in the more general case of heterogeneous markets, we show there exists a continuum of (non-competitive) Markov perfect equilibria. However, a refinement of the Markov property, which we call monotonicity, does suffice to guarantee perfectly competitive equilibria, if, and only if, it is monotonic. The monotonicity property is closely related to the concept of Nash equilibrium with complexity costs

Does Laboratory Trading Mirror Behavior in Real World Markets? Fair Bargaining and Competitive Bidding on EBay

We conducted a controlled field experiment on eBay and examined to what extent both social and competitive laboratory behavior is robust to institutionally complex real world markets with experienced traders, who selected themselves into these markets. EBay’s natural trading system provides bridges between lab and field environment that can be exploited to explore differences in behavior in the two environments. We find that many sellers do not make use of their commitment power as predicted by standard theories of both selfish and social behavior. However, a concern for equity strongly affects outcomes and reputation building in bilateral bargaining, while buyer competition effectively masks this concern and robustly yields equilibrium outcomes. The dichotomy of behaviors mirrors observations in laboratory research. Furthermore, we find that behavioral patterns in the field experiment mirror fully naturally occurring trading patterns in the market.eBay, auctions, behavioral economics, trust, market design

The NBA and the Single Entity Defense: A Better Case?

This Article will explore the relationship between the National Basketball Association, its independently-owned teams, and associated corporate entities, including the Women’s NBA, NBA Properties, NBA Developmental League, NBA China, and single entity analysis under section 1 of the Sherman Act. Section 1 chiefly aims to prevent competitors from combining their economic power in ways that unduly impair competition or harm consumers, be it in terms of raised prices, diminished quality, or limited choices. Single entities are exempt from section 1 because they are considered “one,” rather than competitors, and thus their collaboration does not implicate anticompetitive concerns. In American Needle v. NFL, the Supreme Court will decide whether the National Football League, its teams, and associated corporate entities, constitute a single entity. Other leagues, including the NBA, may be impacted by the Court’s decision. If the NBA were a single entity, it could potentially execute exclusive contracts with video game companies and apparel companies, restrain players’ salaries and employment autonomy, and impose heightened age restrictions on amateur players who seek employment in the NBA, all without concern for section 1 scrutiny. In a recent feature in the Yale Law Journal, I discourage the Court from recognizing the NFL as a single entity but recommend that Congress consider targeted, sports league-related exemptions from section 1. In this Article, I survey whether the NBA’s globalized business agenda and the league’s exposure to competition from foreign professional basketball leagues necessitate that NBA teams act in unison and with a “shared consciousness.” The necessity of cooperation, at least for certain international endeavors, may distinguish NBA teams from teams in NFL, which remain more anchored to domestic operations. To the extent Congress considers legislative exemptions for professional sports leagues, the experience of the NBA, a trailblazer in promoting a league product abroad, may lend insight on how antitrust law should regulate leagues in the years ahead

Competition and well-being: does market competition make people unhappy?

Empirical research on the role of economic institutions for subjective well-being is still widely lacking, while recent economic-experimental outcomes suggest that experienced utility may depend on the intensity of market competition. This paper is the first to empirically analyze the implication of market competition for subjective well-being using real-life survey data on 80,000 individuals in more than 60 countries from the World Values Survey 1997-2001. In support of our hypothesis, we find that market competition aggravates the impact of individual’s bargaining position in economic transactions on her subjective well-being – compared to the least powerful in society. Put differently, we find that market competition enlarges the happiness differences caused by cleavages in socio-economic position. Our results also suggest that competition induced welfare changes are not gender-specific, while a stronger rule of law appears to prevent the generation of such additional benefits or losses. Particularly the latter results call for further economic-experimental corroboration in the laboratory, but also bear important policy implications.Subjective well-being; happiness; utility; competition; rule of law; completeness of contract; laboratory experiment; World Values Survey

Dynamic matching and bargaining games: A general approach

This paper presents a new characterization result for competitive allocations in quasilinear economies. This result is informed by the analysis of non-cooperative dynamic search and bargaining games. Such games provide models of decentralized markets with trading frictions. A central objective of this literature is to investigate how equilibrium outcomes depend on the level of the frictions. In particular, does the trading outcome become Walrasian when frictions become small? Existing specifications of such games provide divergent answers. The characterization result is used to investigate what causes these differences and to generalize insights from the analysis of specific search and bargaining games.Dynamic Matching and Bargaining, Decentralized Markets, Non-cooperative Foundations of Competitive Equilibrium, Search Theory
