摘要：I study a dynamic model of consumer privacy and platform data collection. In each period consumers choose their level of platform activity. Greater activity generates more information about the con-sumer, thereby increasing platform profits. When the platform can commit to the future privacy policy, it collects information by com-mitting to gradually decreasing the level of privacy protection. In the long run consumers lose privacy and receive low payoffs but choose high activity levels. In co...

摘要：This paper analyzes information spillover in a multi-good adverse selection model in which a privately informed seller trades two different goods in two different markets. Buyers learn the seller's information from both the market they participate in and the trading outcomes in the other market. We identify a sufficient negative correlation condition under which information spillover reduces efficiency loss. We also discover a novel type of coordination friction that leads to multiple equilibr...

摘要：Charismatic leaders are often desired. At the same time, experience, especially with demagogues, as well as social science studies, raise doubts about such leaders. This paper offers explanations for char-ismatic leadership's mixed report card. It offers insights into why and when charismatic leadership can be effective; which, when, and why certain groups will prefer more to less charismatic leaders; and how being more charismatic can make leaders worse in other dimen-sions, particularly caus...

摘要：The canonical direct-elicitation approach for measuring individuals' valuations for goods is the Becker-DeGroot-Marschak procedure , which generates willingness-to-pay (WTP) values that are imprecise and systematically biased. We show that enhancing elicited WTP values with supervised machine learning (SML) can improve estimates of peoples' out-of-sample purchase behavior. Furthermore , swapping WTP data with choice data generated from a simple task leads to comparable performance. We quantify...

摘要：We study the problem of learning about the effect of one market-level variable (e.g., price) on another (e.g., quantity) in the presence of shocks to unobservables (e.g., preferences). We show that economic intuitions about the plausible size of the shocks can be informative about the parameter of interest. We illustrate with a main application to the grain market.

摘要：I study how a firm manages its reputation by both investing in the quality of its product and censoring, hiding bad news from con -sumers. Without censorship, the threat of bad news provides strong incentives for investment. I highlight discontinuities in the firm's maximum equilibrium payoff that censorship creates. When censor-ship is inexpensive, the firm never invests and a patient firm's pay-offs approach the lowest possible. In contrast, when censorship is moderately expensive, there exi...

摘要：We propose a model of how multiple societies respond to a common crisis. A government faces a damned-either-way policymaking dilemma: aggressive intervention contains the crisis, but the resulting good outcome makes people skeptical about the costly response; light intervention worsens the crisis and causes the government to be faulted for not doing enough. When multiple societies encounter the crisis sequentially, due to this policymaking dilemma, late societies may underperform despite havi...

摘要：We characterize decreasing impatience, a common behavioral phenomenon in intertemporal choice. Discount factors that display decreasing impatience are characterized through a convexity axiom for investments at fixed interest rates. Then we show that they are equivalent to a geometric average of generalized quasi-hyperbolic discount rates. Finally, they emerge through parimutuel preference aggregation of exponential discount factors. (JEL D15, D61, D91)

摘要：When are differential treatment policies-such as preferential treat-ment, affirmative action, and gender equity policies-justified by efficiency concerns? I propose a nonparametric assignment model where a policymaker assigns agents to different treatments or posi-tions to maximize total surplus, based on the agents' characteristics and noisy information about their types. I provide necessary and sufficient conditions on the agents' signal structures, which charac-terize whether surplus maximi...

摘要：Entry of new firms onto a platform has an ambivalent effect on the incumbent firms operating on the platform: the main tension lies between the negative effects of increased competitive pressure and positive indirect network effects. This paper empirically studies the net effect of these countervailing forces and its dependence on firm quality, using a quasi-exogenous shock on a large online platform. On average, market expansion favors incumbents, though the average effect masks substantial h...
