摘要：A decision maker would like to delegate the acquisition of information to an expert, but is unable to observe the expert's actions, nor is she able to postpone the payment to the expert until the truth is revealed. If the expert can manipulate their report of the realized signal then incentivizing information acquisition is typically impossible. However, by hiring multiple experts and making the payments contingent on the entire vector of signals the decision maker can obtain useful informatio...

摘要：We present results from laboratory experiments studying statistical discrimination and affirmative action. We induce statistical discrimination in simple labor-market interactions between firms and workers. We then introduce affirmative-action policies that vary in the size and duration of a subsidy that firms receive for hiring discriminated-against workers. These different affirmative-action policies have nearly the same effect, and practically eliminate discriminatory hiring practices. Howe...

摘要：Consider a market with two substitute products and a sequence of consumers. The consumers are uncertain about the quality of each product but obtain some private information about it. Additionally, each consumer observes the purchase decisions of her predecessors but not their private information. Absent prices, the standard logic of herding is that all but finitely many consumers may, with positive probability, select the lower quality product. One perspective in the literature is that inform...

摘要：We study the implications of state-dependent costs of policy mismatch in political agency models where politicians have reputational concerns and good politicians share the same objectives as the voters. We find that state-dependent costs can increase the set of parameters where pandering is an equilibrium strategy. Indeed, in our model, pandering can arise even without office rents. Moreover, we show that voters do not necessarily prefer biased politicians to be in favour of the policy that p...

摘要：Afacan (2017) shows that the cumulative offer process respects improvements under the unilateral substitutes, the law of aggregate demand, and the irrelevance of rejected contracts conditions. This note indicates that the proof does not go through. However, a completely new proof is provided, verifying that the result remains correct.(C) 2022 Elsevier Inc. All rights reserved.

摘要：Adding candidates to a one-dimensional common-interest voting model, this paper shows that catering to centrist voters can lower social welfare. The electoral benefit of doing so is weak, so candidates polarize substantially in equilibrium, resolving a long-standing empirical puzzle. (C) 2022 Elsevier Inc. All rights reserved.

摘要：We consider matching-mechanism design in an environment in which agents acquire information about their preferences endogenously. Information is costly; thus, agents acquire information only if it is relevant to their decision-making. Agents' beliefs about their choice set (i.e., the set of objects each agent can obtain) are therefore crucial for incentives in information acquisition. This study demonstrates that the implementation of matching mechanisms changes the equilibrium consequence bec...

摘要：In the context of normal-form games with complete information, we introduce a notion of correlated equilibrium that allows partial delegation to a mediator and ambiguity in the correlation device. Without ambiguity, the sets of equilibrium action distributions are equivalent to those for coarse correlated equilibrium (Moulin and Vial, 1974). With correlation devices that incorporate ambiguity, any action distribution that Pareto dominates a coarse correlated equilibrium or a correlated equilib...

摘要：We show that right-continuous monotone strategies used in Markov perfect equilibria for economic growth models and related dynamic games can be recognised as members of the Hilbert space of square integrable functions of the state variable. We provide an application of this result to a bequest game and point out that this result also holds for the class of left-continuous monotone functions. The result is fundamental for using the Schauder fixed point theorem. Furthermore, it considerably simp...

摘要：We experimentally investigate the role of two-sided reputation-building in dynamic bargaining. In the absence of outside options, rational bargainers have an incentive to imitate obstinate types that are committed to an aggressive demand, inducing delay. Outside options remove this incentive and ensure immediate agreement whenever two rational bargainers match. Our data support the hypothesis that outside options cut down on imitation and ensure timely agreements, but only if subjects share a ...
