1. "Happy Times: Identification from Ordered Response Data," with Nick Netzer, December 2020.
Abstract: Surveys are an important tool in economics and in the social sciences more broadly. However, methods used to analyse ordinal survey data (e.g., ordered probit) rely on strong and often unjustified distributional assumptions. In this paper, we propose using survey response times to solve that problem. Our main identifying assumptions is that individual response time is decreasing in the distance between the value of the latent variable and an indecision threshold. This assumption is supported by a large body of evidence on chronometric effects in psychology and neuroscience. We provide conditions under which the expected value of the latent variable (e.g., average happiness) can be compared across groups, even without making distributional assumptions. By applying it to an online survey experiment, we show how our method can be implemented in practice and gives rise to new insights.
2. "Talent Poaching and Job Rotation," with Diego Battiston and Miguel Espinosa, September 2020.
Abstract: Firms allocate workers to clients to provide services. On the job, workers acquire skills that increase their client-specific productivity and therefore raise the probability that clients poach them. In this paper, we advance the understanding of this important, yet understudied feature of service industries. We show, both theoretically and empirically, that in order to mitigate poaching risk firms may forgo potential productivity gains by moving workers from one client to the other. Focusing on a security service-industry firm in Colombia, we find that an increase in client-specific experience both decreases crime and increases the probability of the outsourcing worker being poached. After a policy change that forbids poaching talent, the firm sharply decreased the frequency of rotation, especially for workers who were more likely to be poached before the policy change. The theoretical model we propose is consistent with these empirical patterns and substantiates the broad applicability of the studied mechanism.
3. "Optimal Contest Design: A General Approach," with Igor Letina and Nick Netzer, May 2020.
Abstract: We consider the design of contests for n agents when the principal can choose both the prize profile and the contest success function. Our framework includes Tullock contests, Lazear-Rosen tournaments and all-pay contests as special cases, among others. We show that the optimal contest has an intermediate degree of competitiveness in the contest success function, and a minimally competitive prize profile with n−1 identical prizes. The optimum can be achieved with a nested Tullock contest. We extend the model to allow for imperfect performance measurement and for heterogeneous agents. We relate our results to a recent literature which has asked similar questions but has typically focused on the design of either the prize profile or the contest success function.
4. "Preference, Confusion and Competition," with Andreas Hefti and Armin Schmutzler, April 2020.
- Revise and Resubmit at The Economic Journal.
Abstract: Do firms seek to make the market transparent, or do they confuse the consumers in their product perceptions? We show that the answer to this question depends decisively on preference heterogeneity. Contrary to the well-studied case of homogeneous goods, confusion is not necessarily an equilibrium in markets with differentiated goods. In particular, if the taste distribution is polarized, so that indifferent consumers are relatively rare, firms strive to fully educate consumers. By contrast, if the taste distribution features a concentration of indecisive consumers, confusion becomes part of the equilibrium strategies. The adverse welfare consequences of confusion can be more severe than with homogeneous goods, as consumers may not only pay higher prices, but also choose a dominated option, or inefficiently refrain from buying. Qualitatively similar insights obtain for political contests, in which candidates compete for voters with heterogeneous preferences.
5. "Designing Organizations in Volatile Markets," with Dimitri Migrow, September 2019.
- Reject & Resubmit at the Journal of Economic Theory.
Abstract: Multinational and multiproduct firms often experience uncertainty in the relative return of conducting activities in different markets due to, for example, exchange rate volatility or the changing prospects of different products. We study how a multi-divisional organization should optimally allocate decision-making authority to its managerial members when operating in such volatile markets. To be able to adapt its decisions to local conditions, the organization has to rely on self-interested division managers to collect and disseminate the relevant information. We show that if communication takes the form of verifiable disclosure, then centralized decision-making does not suffer from information asymmetry and it allows the headquarter of the organization to better cope with the inter-market uncertainty. However, a downside of centralization is that it can discourage information acquisition, and this negative effect is complemented by the need for coordinating the activities of different divisions. As a result, the optimality of decentralized decision-making can actually be driven by a large coordination motive.
