In this paper, we argue that important labor market phenomena can be better understood if one takes (a) the inherent incompleteness and relational nature of most employment contracts and (b) the existence of reference-dependent fairness concerns among a substantial share of the population into account. Theory shows and experiments confirm that, even if fairness concerns were to exert only weak effects in one-shot interactions, repeated interactions greatly magnify the relevance of such concerns on economic outcomes. We also review evidence from laboratory and field experiments examining the role of wages and fairness on effort, derive predictions from our approach for entry-level wages and incumbent workers' wages, confront these predictions with the evidence, and show that reference-dependent fairness concerns may have important consequences for the effects of economic policies such as minimum wage laws.
This article explores use of auctions for privatising public assets. In our model, a single ‘insider’ bidder possesses information about the asset's common value. Bidders are privately informed about their costs of exploiting the asset. Due to the insider's presence, uninformed bidders face a strong winner's curse in standard auctions. We show that the optimal mechanism discriminates against the informationally advantaged bidder. It can be implemented via a two-stage ‘qualifying auction’. In the first stage, non-binding bids are submitted to determine who enters the second stage, which consists of a standard second-price auction augmented with a reserve price.
This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by introducing agents with lower linking costs or higher benefits to others. Furthermore, agents' types may be common knowledge or private information. In all treatments, the (efficient) equilibrium network has a "star" structure. While equilibrium predictions fail completely with homogeneous agents, star networks frequently occur with heterogeneous agents. Stars are not born but rather develop:
with a high-value agent, the network's centrality, stability, and efficiency all increase over time. A structural econometric model based on best response dynamics and other-regarding preferences is used to analyze individual linking behavior. Maximum-likelihood estimates
of the underlying structural parameters, obtained by pooling data from several treatments, allow us to explain the main treatment effects.
What can business do to cope more successfully with terrorism?” The policy against terrorism available to business is a neglected issue in the scholarly literature especially in so far as individual firms rather than the business sector as a whole are concerned. Two sets of proposals are advanced, based on an economic analysis of terrorism. The first set discusses possibilities to reduce terrorists’ incentives to attack business premises; the second part outlines proposals designed to minimize the costs to businesses once a terrorist attack has taken place, hence reducing the impact.
Environmental markets have several institutional features that provide a new context for the use of auctions and that have not been studied previously. This paper reports on laboratory experiments testing three auction forms — niform and discriminatory price sealed-bid auctions and an ascending clock auction. We test the ability of subjects to tacitly or explicitly collude in order to maximize profits. Our main result is that the discriminatory and uniform price auctions produce greater revenues than the clock
auction, both with and without explicit communication. The clock appears to facilitate successful collusion, both because of its sequential structure and because it allows bidders to focus on one dimension of cooperation (quantity) rather than two (price and quantity).
Are initial competitive advantages self-reinforcing, so that markets exhibit an endogenous tendency to be dominated by only a few firms? Although this question is of great economic importance, no systematic empirical study has yet addressed it. Therefore, we examine experimentally whether firms with an initial cost advantage are more likely to invest in marginal cost reductions than firms with higher initial costs. We find that the initial competitive advantages are indeed self-reinforcing, but subjects in the role of firms overinvest relative to the Nash equilibrium. However, the pattern of overinvestment even strengthens the tendency towards self-reinforcing cost advantages relative to the theoretical prediction. Further, as predicted by the Nash equilibrium, mean-preserving spreads of the initial cost distribution have no effects on aggregate investments. Finally, investment spillovers reduce investment, and investment is higher than the joint-profit maximizing benchmark for the case without spillovers and lower for the case with spillovers.
This article seeks to assess whether physician payment reforms in the United States and Switzerland were likely to attain their objectives. We first introduce basic contract theory, with the organizing principle being the degree of information asymmetry between the patient and the health care provider. Depending on the degree of information asymmetry, different forms of payment induce “appropriate” behavior. These theoretical results are then pitted against the RBRVS of the United States to find that a number of its aspects are not optimal. We then turn to Switzerland’s Tarmed and find that it fails to conform with the prescriptions of economic contract theory as well. The article closes with a review of possible reforms that could do away with uniform fee schedules to improve the performance of the health care system.
We consider a setting in which two potential merger partners each possess private information pertaining
both to the profitability of the merged entity and to stand-alone profits, and we investigate the extent to
which this private information makes ex-post regret an unavoidable phenomenon in merger negotiations.
To this end, we consider ex-post incentive compatible mechanisms, which use both players’ reports to determine whether or not a merger will take place and what each player will earn in each case. When the outside option of at least one player is known, the efficient merger decision can be implemented by such a mechanism under plausible budget-balance requirements. When neither outside option is known, we show that the potential for regret-free implementation is much more limited, unless the budget balance condition is relaxed to permit money-burning in the case of false reports.
