Exclusion of Extreme Jurors and Minority Representation: The Effect of Jury Selection Procedures
- with Martin Van der Linden, February 2021
- More info...
- Abstract
  We compare two established jury selection procedures meant to safeguard against the inclusion of biased jurors that are also perceived as causing minorities to be under-represented in juries. The Strike and Replace procedure presents potential jurors one-by-one to the parties, while the Struck procedure presents all potential jurors before the parties exercise vetoes. In equilibrium, Struck more effectively excludes extreme jurors than Strike and Replace but leads to a worse representation of minorities. Simulations suggest that the advantage of Struck in terms of excluding extremes is sizable in a wide range of cases. In contrast, Strike and Replace only provides a significantly better representation of minorities if the minority and majority are heavily polarized. When parameters are estimated to match the parties' selection of jurors by race with jury-selection data from Mississippi in trials against black defendants, the procedures' outcomes are substantially different, and the size of the trade-off between objectives can be quantitatively evaluated.

Spatial-SIR with Network Structure and Behavior: Lockdown Rules and the Lucas Critique
- with Alberto Bisin, February 2021, under review
- More info...
- Abstract
  We extend a Spatial-SIR model of the diffusion of an infection to include heterogeneous agents interacting socially in three different types of location every day: City, School/Work, and Home. Contagion-risk averse agents respond behaviorally to the diffusion of the epidemic by limiting their social interactions. Firms also respond, by allowing employees to work remotely depending on their productivity. We study the effects of several non-pharmaceutical intervention on epidemic dynamics, e.g. selective lockdowns. Simulations illustrate how the network structure generates local herd immunities along socio-demographic dimensions, affecting policy outcomes. Finally, substantiating a ``Lucas critique'' argument, we assess the cost of naive policies ignoring the behavioral responses of agents and firms.

Learning Epidemiology by Doing: The Empirical Implications of a Spatial SIR Model with Behavioral Responses

with Alberto Bisin, February 2021 (Revision Resubmitted)
More info...

Abstract
We simulate a spatial behavioral model of the diffusion of an infection to understand the role of geographical characteristics: city size, density, distribution of initial outbreaks, movement of agents. We show that several invariance properties of the SIR model with respect to these variables do not hold when agents are placed in a two dimensional space. Local herd immunity plays a fundamental role in changing the dynamics of the infection. We also show that geographical factors affect how behavioral responses affect the epidemics. We derive relevant implications for the estimation of epidemiological models with panel data from several geographical units.

The Empirical Content of Models with Multiple Equilibria in Economies with Social Interactions
- with Giorgio Topa and Alberto Bisin
- More info...
- Abstract
  We study a general class of models with social interactions that might display multiple equilibria. We propose an estimation procedure for these models and evaluate its efficiency and computational feasibility relative to different approaches taken to the curse of dimensionality implied by the multiplicity. Using data on smoking among teenagers, we implement the proposed estimation procedure to understand how group interactions affect health-related choices. Wefind that interaction effects are strong both at the school level and at the smaller friends-network level. Multiplicity of equilibria is pervasive at the estimated parameter values, and equilibrium selection accounts for about 15 percent of the observed smoking behavior. Counterfactuals show that student interactions, surprisingly, reduce smoking by approximately 70 percent with respect to the equilibrium smoking that would occur without interactions.

The Welfare Effects of Non-Linear Health Dynamics
- with Chiara Dal Bianco
- More info...
- In preparation
- Abstract
  In this paper we estimate a non-parametric model of health dynamics to investigate the effect of health shocks on the consumption, savings, and wealth distributions and their dynamics over the life cycle. Several articles study this question by positing a binary or 3-valued health measure that evolves with a first order Markov process. While computationally less demanding, this approach may miss important effects that originate from the complex dynamics of the health process, particularly if one is interested in studying the effects of especially severe and persistent shocks. To this end, we construct a continuous measure of health. We derive a health index using several objective measures of health and adopting a latent variable model in the spirit of Bound (1991). Next, we show that health follows a complex dynamics, with nonlinear persistence and age dependence. Therefore, we adopt the quantile-based panel data method from Arellano, Blundell and Bonhomme (2017) to estimate health's persistent and transitory components. We incorporate this health process into a dynamic model where agents receive utility from consumption, leisure, and bequests of assets, and choose, in each period, labor market participation and savings. We estimate this model with the Method of Moments procedure using English Longitudinal Study of the Ageing (ELSA)'s panel of households aged 50 and above. We use the model and its estimated parameters to simulate various counterfactuals in order to understand the role and ditributional consequences of severe health shocks and their persistence on the elderly's economic outcomes.

- More info...
- Abstract
  In Historical Economics, Persistence studies document the persistence of some historical phenomenon or leverage this persistence to identify causal relationships of interest in the present. In this chapter, we analyze the implications of allowing for heterogeneous treatment effects in these studies. We delineate their common empirical structure, argue that heterogeneous treatment effects are likely in their context, and propose minimal abstract models that help interpret results and guide the development of empirical strategies to uncover the mechanisms generating the effects.

Testing for Asymmetric Employer Learning and Statistical Discrimination

Applied Economics, (Published online 2020) DOI: 10.1080/00036846.2020.1830939 (with Suqin Ge and Beibei Zhu)

Abstract
We test if firms statistically discriminate workers based on race when employer learning is asymmetric. Using data from the NLSY79, we find evidence of asymmetric employer learning. In addition, employers statistically discriminate against non-college educated black workers at time of hiring. We also find that employers directly observe most of the productivity of college graduates at hiring and learn very little over time about these workers.

Do Female Executives Make a Difference? The Impact of Female Leadership on Gender Gaps and Firm Performance
- The Economic Journal Vol. 129(622), August 2019, 2390–2423 (with Luca Flabbi, Mario Macis and Fabiano Schivardi).
- More info...
- Abstract
  We investigate the effects of female executives on gender-specific wage distributions and firm performance. We find that female leadership has a positive impact at the top of the female wage distribution and a negative impact at the bottom. Moreover, the impact of female leadership on firm performance increases with the share of female workers. Our empirical strategy accounts for the endogeneity induced by the non-random assignment of executives to firms by including in the regressions firm fixed effects, by generating controls from a two-way fixed effects regression, and by building instruments based on regional trends. The empirical findings are consistent with a model of statistical dis- crimination where female executives are better equipped at interpreting signals of productivity from female workers. The evidence suggests substantial costs of under-representation of women at the top of the corporate hierarchy.

Endogenous Comparative Advantage
- Scandinavian Journal of Economics Vol. 121(3), 2019, 1088-1124 (First published online 22 February 2018), (with Peter Norman)
- More info...
- Abstract
  We develop a model of trade between identical countries. Workers endogenously acquire skills that are imperfectly observed by firms, who therefore use aggregate country investment as the prior when evaluating workers. This creates an informational externality interacting with general equilibrium effects on each country's skill premium. Asymmetric equilibria with comparative advantages exist even when there is a unique equilibrium under autarky. Symmetric, no-trade equilibria may be unstable under free trade. Welfare effects are ambiguous: trade may be Pareto improving even if it leads to an equilibrium with rich and poor countries, with no special advantage to country size.

The Impact of Obesity on Wages: the Role of Personal Interactions and Job Selection
- Labour Vol. 33(2), June 2019, 125-146 (with Tommaso Tempesti and D. Sebastian Tello-Trillo)
- More info...
- Abstract
  We estimate the effects of obesity on wages accounting for the endogenous selection of workers into jobs requiring different levels of personal interactions in the workplace. Using data from the National Longitudinal Survey of Youth 1979 combined with detailed information about occupation characteristics from O*Net, we confirm the results from the literature finding a wage penalty for obese white women. This penalty is higher in jobs that require a high level of personal interactions. Accounting for job selection does not significantly change the estimated wage penalty.

The Effect of Job Flexibility on Women Labor Market Outcomes: Estimates from a Search and Bargaining Model
- Journal of Econometrics Vol. 168, 2012, 81-95 (with Luca Flabbi)
- More info...
- Abstract
  This paper presents and estimates a search model of the labor market where jobs are characterized by wages and work-hours exibility. Flexibility is valued by workers, and is costly to provide for employers. The model generates observed wage distributions directly related to the preference for exibility parameters: the higher the preference for exibility, the wider is the support of the wage distribution at exible jobs and the larger is the discontinuity between the wage distribution at exible and non- exible jobs. Results show that more than one third of women place positive value to exibility, and that reducing the cost of exibility may considerably reduce the gender wage gap.

Abstract
This chapter surveys the theoretical literature on statistical discrimination and affirmative action. This literature suggests different explanations for the existence and persistence of group inequality. This survey highlights such differences and describes in these contexts the effffects of color-sighted and color-blind affrmative action policies, and the efficiency implications of discriminatory outcomes

Statistical Discrimination,

- Abstract
  Statistical discrimination is a theory of inequality between demographic groups based on stereotypes that do not arise from prejudice or racial and gender bias.When rational, information-seeking decision makers use aggregate group characteristics, such as group averages, to evaluate individual personal characteristics, individuals belonging to different groups may be treated differently even if they share identical observable characteristics in every other aspect. Discrimination can be the agents’ efficient response to asymmetric beliefs, or discriminatory outcomes may display an element of inefficiency: the disadvantaged group could perform better if beliefs were not asymmetric across groups (but beliefs are asymmetric because the disadvantaged are not performing as well as the dominant group)

The Performance of the Pivotal-Voter Model in Small-scale elections: Evidence from Texas Liquor Referenda
- Journal of Public Economics Vol. 92(4), April 2008, 582-96 (with Stephen Coate and Michael Conlin)
- More info...
- Abstract
  This paper explores the ability of pivotal-voter models to explain voter behavior in small-scale elections using data from Texas liquor referenda. The findings provide little support for the view that pivotal-voter models are a reasonable theory for understanding small-scale elections. Interestingly, this is not because they cannot explain the levels of turnout in the data, but rather because they cannot explain the size of the winning margins. The logic of pivotal-voter models implies that elections must be expected to be close even if there is a significant difference between the sizes of the groups or the intensity of their preferences. With even a relatively small number of eligible voters, elections that are expected to be close ex ante must end up being close ex post. However, in the data, winning margins are often significant.

Electoral Design and Voter Welfare from the U.S. Senate: Evidence from a Dynamic Selection Model
- Review of Economic Dynamics Vol. 11(1), January 2008, 1-17 (with by Gautam Gowrisankaran and Matt Mitchell)
- More info...
- Abstract
  Since 1914, the U.S. Senate has been elected and incumbent senators allowed to run for reelection without limit. This differs from several other elected offices in the U.S., which impose term limits on incumbents. Term limits may harm the electorate if tenure is beneficial or if they force high quality candidates to retire but may also benefit the electorate if they cause higher quality candidates to run. We investigate how changes in electoral design affect voter utility by specifying and structurally estimating a dynamic model of voter decisions. We find that tenure effects for the U.S. Senate are negative or small and that incumbents face weaker challengers than candidates running for open seats. Because of this, term limits can significantly increase voter welfare.

Persistent Distortionary Policies with Asymmetric Information ,
- American Economic Review Vol. 96(1), March 2006, 387-93 (with Matt Mitchell)
- More info...
- Abstract
  Why are distortionary policies used when seemingly Pareto improvements exist? According to a standard textbook argument, a Pareto improvement can be obtained by eliminating the distortions, compensating the losers with a lump sum transfer and redistributing the gains that are left over. We relax the assumption that winners know the losses suffered by the losers and show that the informationally efficient method of compensating losers may involve the use of seemingly inefficient (but informationally efficient) distortionary policies. The risk of over-compensating losers may make distortions informationally efficient.

A General Equilibrium Model of Statistical Discrimination,
- Journal of Economic Theory Vol. 114 (1), January 2004, 1-30 (with Peter Norman)
- More info...
- Abstract
  We study a general equilibrium model with endogenous human capital formation in which ex ante identical groups may be treated asymmetrically in equilibrium. The interaction between an informational externality and general equilibrium effects creates incentives for groups to specialize, and discrimination may arise even if the corresponding model with a single group has a unique equilibrium. The dominant group gains from discrimination, rationalizing why a majority may be reluctant to eliminate discrimination. The model is also consistent with "reverse discrimination'' as a remedy against discrimination since it may be necessary to decrease the welfare of the dominant group to achieve parity.

Empirical Implications of Statistical Discrimination on the Returns to Measures of Skill
- Annales d'Économie et de Statistique Vol. 71-72, July-December 2003, 399-417 (with Peter Norman)
- More info...
- Abstract
  This paper investigates how lack of information may bias the investigator's assessment of the presence of statistical discrimination. We show that the nature of the bias is such that statistical discrimination may be rejected in a Mincerian regression even when the data is generated from an equilibrium with statistical discrimination. This may occur even when the investigator has a more informative signal of productivity the employers have.

The Effect of Statistical Discrimination on Black-White Wage Inequality: Estimating a Model with Multiple Equilibria
- International Economic Review Vol. 44(2), May 2003, 467-500
- More info...
- Abstract
  This paper presents the structural estimation of a statistical discrimination model. Although the model is capable of displaying multiple equilibria, an estimation strategy that identifies both the parameters of the model and the equilibrium chosen by the economic agents is developed and empirically implemented. A comparison between the equilibria that were selected in the economy over time and the other potential equilibria reveals that the decline in wage inequality experienced in the U.S. economy in the last thirty years cannot be attributed to changes in the equilibrium selection.

Affirmative Action in a Competitive Economy
- Journal of Public Economics Vol. 87(3-4), March 2003, 567-594 (with Peter Norman)
- More info...
- Abstract
  We consider a model of endogenous human capital formation with competitively determined wages. In the presence of two distinguishable, but ex ante identical groups of workers, we show that discrimination is sustainable in equilibrium, even if the corresponding model with a single group of workers has a unique equilibrium. An affirmative action policy consisting of a quota may ``fail'' in the sense that there still may be equilibria where groups are treated differently. However, the incentives to invest for agents in the discriminated group are improved by affirmative action if the initial equilibrium is the most discriminatory equilibrium in the model without the policy. The welfare effects are ambiguous. We demonstrate that it is possible that the policy makes the intended beneficiaries worse off: even if the starting point is the most discriminatory equilibrium the expected payoff may decrease for all agents in the target group
