摘要：We study the role of endogenous trust in amplifying ideological bias. Agents in our model learn a sequence of states from sources whose accuracy is ex ante uncertain. Agents learn these accuracies by comparing their own reasoning about the states based on introspection or direct experience to the sources' reports. Small biases in this reasoning can cause large ideological differences in the agents' trust in information sources and their beliefs about the states, and may lead agents to become o...

摘要：A continuum of citizens with heterogeneous opportunity costs participates in a protest with well-defined demands. As long as the government doesn't concede, it pays a cost increasing in time and participation. Citizens who are part of the victory team enjoy a veteran reward. Every equilibrium with protest displays a buildup stage during which citizens join the protest but the government ignores them, a peak at which the government concedes with positive probability, and a decay stage in which ...

摘要：This paper provides the first systematic analysis of the role of contracting environments on market outcomes and efficiency in markets with hidden information using experimental methods. When markets are plagued by hidden information, competition does not necessarily ensure efficient market outcomes. This crucially depends on the nature of the hidden information. We present a parsimonious experimental design that serves to compare the different contracting environments for both types of hidden...

摘要：Labor markets unravel when workers and firms match inefficiently early under limited information. I argue that a significant determinant of unraveling is the presence of a secondary market, where firms can poach workers, and its transparency: how well firms can ascertain workers' value once they are employed by competitors. While early hiring reduces the probability of hiring a high-type worker, it prevents rivals from learning about the worker, making poaching difficult. When secondary market...

摘要：We conduct a large-scale experiment to measure elementary aspects of strategic thinking skills and their linkage to labor market outcomes. Two incentivized measures of higher-order rationality and backward induction are developed. Males' (females') strategic thinking skills are positively (negatively) associated with individual labor income. However, among married individuals, strategic thinking skills are significantly and positively associated with their household labor income regardless of ...

摘要：In a model of moral hazard in teams, we demonstrate that firms'concerns about low trust among teammates can justify two common but otherwise puzzling patterns: information waste and transparency trap. We find firms predominantly employ individual performance bonuses, ignoring that relevant information about team output and competition for better contracts leads workers into a self-defeating race toward effort transparency. Notably, the firm may be indifferent to or benefit from trust concerns,...

摘要：This paper offers the first systematic quantitative assessment of default-option interventions designed to mitigate Google's search dominance. By analyzing interventions in the European Economic Area (EEA), Russia, and Turkey, we find that across all three cases, changes to default settings effectively reduced Google's market share. The causal impact amounts to less than 1 percentage point in the EEA and over 10 percentage points in Russia and Turkey. Differences arise from intervention nuance...

摘要：Large beer and spirits makers expanded abroad mainly by acquiring local brands. Exploiting market share data in 76 countries and changes in brand ownership from 2007 to 2018, we estimate that owners matter little for brand performance, except via a negative consumer response to foreign ownership. Counterfactuals indicate that market power increases were large enough to yield higher profits for most mergers without relying on fixed-cost savings. Emulating procompetition policies used by the Uni...

摘要：We propose a simple method for eliciting individual time preferences without estimating utility functions even in settings where background consumption changes over time. It relies on eliciting preferences for receiving high stakes lottery tickets at different points in time. In a standard intertemporal choice model high rewards decouple lottery choices from variation in background consumption. We investigate robustness to other assumptions theoretically, and validate our elicitation method ex...

摘要：We study the effects of church tax exemptions on the structure of religious markets. Using the Brazilian experience as a showcase, we develop and estimate a dynamic entry model of religious organizations based on temple opening and closure in geographically isolated markets. Counterfactual simulations suggest that tax exemptions stimulated entry by all religions, but disproportionately benefited evangelical denominations: The evangelical share of temples increased by approximately 20 percentag...
