摘要：This paper argues for efficient environmental regulations that equate the marginal damage of pollution to marginal abatement costs across space. The paper estimates the source-specific marginal damages of air pollution and calculates the welfare gain from making the current sulfur dioxide allowance trading program for power plants more efficient. The savings from using trading ratios based on marginal damages are between $310 and $940 million per year. The potential savings from setting aggreg...

摘要：We present a laboratory, experiment that measures the effects of induced group identity, on social preferences. We find that when participants are matched with an ingroup member, they show a 47 percent increase in charity concerns and a 93 percent decrease in envy. Likewise, participants are 19 percent more likely to reward an ingroup match for good behavior, but 13 percent less likely to punish an ingroup match for misbehavior. Furthermore, participants are significantly more likely to choose...

摘要：We present the results of an experiment that attempts to measure the social value of groups. In the experiment, group membership is induced artificially: subjects interact with insiders and outsiders in trust games and periodically enter markets where they can trade group membership. We find that trust falls with groups because of negative discrimination against outsiders. Against this, however, there is evidence that group membership provides a psychological benefit, albeit one that may induc...

摘要：We report results from a randomized natural field experiment conducted in a restaurant dining setting to distinguish the observational learning effect from the saliency effect. We find that, when customers are given ranking information of the five most popular dishes, the demand for those dishes increases by 13 to 20 percent. We do not find a significant saliency effect. We also find modest evidence that the observational learning effects are stronger among infrequent customers, and that dinin...

摘要：Thirty years have passed since a small group of theorists began applying concepts and tools from industrial organization to the analysis of international trade. The new models of trade that emerged from that work didn't supplant traditional trade theory so much as supplement it, creating an integrated view that made sense of aspects of world trade that had previously posed major puzzles. The new trade theory-an unfortunate phrase, now quite often referred to as the old new trade theory-also he...

摘要：This paper presents a model in which price setting firms decide what to pay attention to, subject to a constraint on information flow. When idiosyncratic conditions are more variable or more important than aggregate conditions, 'firms pay more attention to idiosyncratic conditions than to aggregate conditions. When we calibrate the model to match the large average absolute size of price changes observed in micro data, prices react fast and by large amounts to idiosyncratic shocks, but only slo...
