摘要：Nash's characterization of his famous bargaining solution has long faced the objection of being welfarist: a bargaining situation is captured by a utility possibility set and a utility vector prevailing in case of disagreement, with no further information regarding the underlying economic environment. The present paper shows that a straightforward adaptation of Nash's axioms in a natural economic environment with lotteries does characterize his solution. A similar result holds for Kalai and Sm...

摘要：We analyze sunspot-driven fluctuations in the standard two-sector RBC model with moderate increasing returns to scale and generalized no-income-effect preferences a la Greenwood, Hercovitz and Huffman [13]. We provide a detailed theoretical analysis enabling us to derive relevant bifurcation loci and to characterize the steady-state local stability properties as a function of various structural parameters. We show that local indeterminacy occurs through flip and Hopf bifurcations for a large s...

摘要：We study the implications of credit market frictions for the dynamics of corporate capital structure and the risk of default of corporations. To do so, we develop a dynamic capital structure model in which firms face uncertainty regarding their ability to raise funds in credit markets and have to search for investors when seeking to adjust their capital structure. We provide a general analysis of shareholders' dynamic financing and default decisions, show when Markov perfect equilibria in fina...

摘要：We analyze optimal monetary policy in a sticky price model with open market operations. The central bank sets the policy rate and can, additionally, control the amount of money by rationing money supplied against eligible securities. Optimal policy under money rationing is shown to enhance welfare in the longrun and in the short-run compared to a conventional optimal policy regime where money supply is not rationed and satiates money demand. Specifically, this property is shown to apply when p...

摘要：We consider a one-sided assignment market or exchange network with transferable utility and the dynamics of bargaining in such a market. Our dynamical model is local, involving iterative updates of 'offers' based on estimated best alternative matches, in the spirit of pairwise Nash bargaining. Agents are not strategic in our model. We establish that when a balanced outcome (a generalization of the pairwise Nash bargaining solution to networks) exists, our dynamics converges rapidly to such an ...

摘要：We study mechanism design in non-Bayesian settings of incomplete information, when the designer has no information about the players, and the players have arbitrary, heterogeneous, first-order, and possibilistic beliefs about their opponents' payoff types. Using such beliefs, in auctions of a single good, we define a revenue benchmark at least as high as the second-highest valuation, and sometimes much higher; prove that it is not meaningfully achievable via traditional notions of implementati...

摘要：We study from an algorithmic viewpoint anonymous games [22,4,5,19]. In these games a large population of players shares the same strategy set and, while players may have different payoff functions, the payoff of each depends on her own choice of strategy and the number of the other players playing each strategy (not the identity of these players). We show that, the intractability results of [12] and [10] for general games notwithstanding, approximate mixed Nash equilibria in anonymous games ca...

摘要：We study the optimal dynamics of incentives for a manager whose ability to generate cash flows changes stochastically with time and is his private information. We show that distortions (aka, wedges) under optimal contracts may either increase or decrease over time. In particular, when the manager's risk aversion and ability persistence are small, distortions decrease, on average, over time. For sufficiently high degrees of risk aversion and ability persistence, instead, distortions increase, o...

摘要：We study firms' incentives to acquire costly information in booms and recessions to investigate the role of endogenous information in accounting for business cycles. Our model predicts that, for a wide range of parameter values, firms have a stronger incentive to acquire information when the economy has been in a recession and a pessimistic belief about the state of the economy prevails than after a boom when firms share an optimistic belief. The equilibrium price system, which features endoge...

摘要：Does encouraging trader participation enhance market competitiveness? This paper shows that, when trader preferences are interdependent, trader market power does not necessarily decrease with greater participation, and traders need not become price takers in large markets. Thus, larger markets can be less liquid and associated with lower ex ante welfare. In the linear-normal model, the necessary and sufficient condition on the information structure is provided under which price impact is monot...
