摘要：Cyclical patterns in earnings can arise when contracts between firms and their workers are incomplete, and when workers cannot borrow or lend so as to smooth their consumption. Effort cycles generate occasional large changes in earnings. These large changes are transitory, consistent with recent empirical findings. (C) 2020 Elsevier Inc. All rights reserved.

摘要：We consider a combinatorial auction model where preferences of agents over bundles of objects and payments need not be quasilinear. However, we restrict the preferences of agents to be dichotomous. An agent with dichotomous preference partitions the set of bundles of objects as acceptable and unacceptable, and at the same payment level, she is indifferent between bundles in each class but strictly prefers acceptable to unacceptable bundles. We show that there is no Pareto efficient, dominant s...

摘要：We present partial strategyproofness, a new, relaxed notion of strategyproofness for studying the incentive properties of non-strategyproof assignment mechanisms. Informally, a mechanism is partially strategyproof if it makes truthful reporting a dominant strategy for those agents whose preference intensities differ sufficiently between any two objects. We demonstrate that partial strategyproofness is axiomatically motivated and yields a parametric measure for how strategyproof an assignment m...

摘要：We present a model where quantitative trading - trading strategies based on the quantitative analysis of prices, volumes, and other asset and market characteristics - is systematically profitable for sophisticated traders whose only source of private information is knowing better than other market participants how many fundamental traders, i.e., traders informed about fundamentals, are active in the market. In equilibrium, the direction of optimal quantitative trading depends on the number of ...

摘要：Evidence suggests that individuals and firms are sometimes more innovative when subject to low-powered incentives. I offer an explanation based on a characteristic feature of creative work: hitting dead ends. An agent works on successive ideas, each of which may lead to a breakthrough with some probability. At any time, the agent may abandon her current idea, incurring delay to come up with a new one. Larger rewards and greater impatience cause the agent to spend more time on each idea and to ...

摘要：Envy-freeness and Pareto Efficiency are two major goals in welfare economics. The existence of an allocation that satisfies both conditions has been studied for a long time. Whether items are indivisible or divisible, it is impossible to achieve envy-freeness and Pareto Efficiency ex post even in the case of two people and two items. In contrast, in this work, we prove that, for any cardinal utility functions (including complementary utilities for example) and for any number of items and playe...

摘要：This paper introduces incomplete information into the standard cultural transmission framework (Bisin and Verdier, 2001). We consider parents having incomplete information about population shares and about the efficiency of their transmission technology. We show that conjectures about population shares are the key determinants of long-run population configurations. Namely, if these conjectures are positively or mildly negatively biased, there is always long-run cultural heterogeneity. If, inst...

摘要：We introduce extended proper equilibrium, which refines proper equilibrium (Myerson, 1978) by adding across-player restrictions on trembles. This refinement coincides with proper equilibrium in games with two players but adds new restrictions in games with three or more players. One implication of these additional restrictions is that any tremble that is costless in equilibrium is regarded by all as more likely than any costly tremble, even one by a different player. At least one extended prop...

摘要：Suppose that the conditional distributions of (x) over tilde (resp. (y) over tilde) can be ranked according to the m-th (resp. n-th) risk order. Increasing their statistical concordance increases the (m, n) degree riskiness of ((x) over tilde, (y) over tilde), i.e., it reduces expected utility for all bivariate utility functions whose sign of the (m, n) cross-derivative is (-1)(m+n+1). This means in particular that this increase in concordance of risks induces a m + n degree risk increase in (...

摘要：Financial crises are anticipated by leverage build-up and asset price booms and followed by sharp de-leveraging and asset price burst. Leverage pro-cyclicality, debt margins counter-cyclicality and heightened asset price volatility are often hard to reconcile with credit frictions models, with and without occasionally binding constraints. We show that a model in which the anticipatory effects of occasionally binding collateral constraints interact with borrowers' time-varying risk-attitudes (m...
