Players choose an action before learning an outcome chosen according to an unknown and history-dependent stochastic rule. Procedures that categorize outcomes, and use a randomized variation on fictitious play within each category are studied. These procedures are “conditionally consistent:” they yield almost as high a time-average payoff as if the player knew the conditional distributions of actions given categories. Moreover, given any alternative procedure, there is a conditionally consistent procedure whose performance is no more than epsilon worse regardless of the discount factor. We also discuss cycles, and argue that the time-average of play should resemble a correlated equilibrium. Journal of Economic Literature Classification Numbers: C72, C73, C63, D83. 相似文献

Despite recent interest in flipped classrooms, rigorous research evaluating their effectiveness is sparse. In this study, the authors implement a randomized controlled trial to evaluate the effect of a flipped classroom technique relative to a traditional lecture in an introductory undergraduate econometrics course. Random assignment enables the analysis to eliminate other potential explanations of performance differences between the flipped and traditional classrooms, while assignment of experimental condition by section and lesson enables improved statistical precision. The authors find that the flipped classroom increases scores on medium-term, high-stakes assessments by 0.16 standard deviation, with similar long-term effects for high-performing students. Estimated impacts are robust to alternative specifications accounting for possible spillover effects arising from the experimental design. 相似文献

Costly punishment can facilitate cooperation in public-goods games, as human subjects will incur costs to punish non-cooperators even in settings where it is unlikely that they will face the same opponents again. Understanding when and why it occurs is important both for the design of economic institutions and for modeling the evolution of cooperation. Our experiment shows that subjects will engage in costly punishment even when it will not be observed until the end of the session, which supports the view that agents enjoy punishment. Moreover, players continue to cooperate when punishment is unobserved, perhaps because they (correctly) anticipate that shirkers will be punished: Fear of punishment can be as effective at promoting contributions as punishment itself. 相似文献

Griffiths and Winters [Griffiths, M., Winters, D., 1997. On a preferred habitat for liquidity at the turn-of-the-year: evidence from the term-repo market, Journal of Financial Services Research 12, 21–38] find a year-end preferred habitat for liquidity for US repo rates, and, later [Griffiths, M., Winters, D., 2005. The-turn-of-the-year in money markets: tests of the riskshifting window dressing and preferred habitat hypotheses, Journal of Business 78, 1337–1364] find a similar preferred habitat for US money market instruments. Kotomin et al. [Kotomin, V., Smith, S., Winters, D., 2008. Preferred habitat for liquidity in international shortterm interest rates, Journal of Banking and Finance 32, 240–250] document the preferred habitat in LIBOR for the major world currencies, excluding the British pound. We examine the robustness of these results using pound sterling and euro repo rates and find a year-end preferred habitat for liquidity in the euro repo rates. The British interest rates continue to behave differently, and we provide a possible explanation as to why this occurs. 相似文献

We evaluate supervisory practices in enforcing the Community Reinvestment Act (CRA) by examining whether or not supervisors consider observable, bank-specific characteristics in (1) scheduling CRA compliance examinations and (2) determining whether, and for how long, a given CRA rating persists. Failure to confirm such a relationship would be consistent with criticism that the evaluation criteria are so vague that supervisors can essentially assign any rating they want for compliance purposes. Analysis of a sample of several thousand commercial banks, observed over a relatively stable regulatory regime, indicates that both examination scheduling and the persistence of examination ratings are associated with residential loan levels, a presumed cornerstone of the CRA, as well as other financial, regulatory and market factors. We conclude that CRA enforcement during this period reflected, at least in part, objective evaluation criteria. 相似文献

Allen and Saunders [Allen, A., and A. Saunders. “Bank Window Dressing: Theory and Evidence.” Journal of Banking and Finance 16 (1992), 583–623.] document abnormal behavior of bank assets and liabilities at the turn-of-the-quarter and attribute it
to window dressing by banks. Using different methods we re-visit bank turn-of-the-quarter balance sheet activity. We also
examine quarter-end changes in the effective fed funds rates and fed funds rate standard deviations. We confirm the presence
of turn-of-the-quarter activity on bank balance sheets and in the fed funds market. However, we conclude that the turn-of-the-quarter
effects are more consistent with customer preferred habitats than window dressing. 相似文献

Large in‐person gatherings of travelers who do not socially distance are classified as the “highest risk” for COVID‐19 spread by the Centers for Disease Control and Prevention (CDC). From August 7–16, 2020, nearly 500,000 motorcycle enthusiasts converged on Sturgis, South Dakota for its annual rally in an environment without mask‐wearing requirements or other mitigating policies. This study is the first to explore this event's public health impacts. First, using anonymized cell phone data, we document that foot traffic at restaurants/bars, retail establishments, and entertainment venues rose substantially at event locations. Stay‐at‐home behavior among local residents fell. Second, using a synthetic control approach, we find that the COVID‐19 case rate increased substantially in Meade County and in the state of South Dakota in the month following the Rally. Finally, using a difference‐in‐differences model to assess nationwide spread, we find that following the Sturgis event, counties outside of South Dakota that contributed the highest inflows of rally attendees experienced a 6.4–12.5% increase in COVID‐19 cases relative to counties without inflows. Our findings highlight that local policy decisions assessing the tradeoff between local economic benefits and COVID‐19 health costs will not be socially optimal in the presence of large contagion externalities. 相似文献

We study the perfect type-contingently public ex-post equilibrium (PTXE) of repeated games where players observe imperfect public signals of the actions played, and both the payoff functions and the map from actions to signal distributions depend on an unknown state. The PTXE payoffs when players are patient are determined by the solutions to a family of linear programming problems. Using this characterization, we develop conditions under which play can be as if the players have learned the state. We provide a sufficient condition for the folk theorem, and a characterization of the PTXE payoffs in games with a known monitoring structure. 相似文献
