摘要：This study uses sociometric data to show that social connections in the classroom shape the diffusion of the negative externalities on cognitive achievement generated by abused and neglected peers. We find the strongest negative effects for students who are socially closest to the abused and neglected peer. The fade-out rate of the negative externality is such that being three peers away from an abused and neglected peer is equivalent to having no such peers. Although the inverse effect-distan...

摘要：We propose a new nonparametric modeling framework for causal inference when outcomes depend on how agents are linked in a social or economic network. Such network interference describes a large literature on treatment spillovers, social interactions, social learning, information diffusion, disease and financial contagion, social capital formation, and more. Our approach works by first characterizing how an agent is linked in the network using the configuration of other agents and connections n...

摘要：This paper studies income inequality and optimal taxation policies in a talent-to-task assignment model of self-selection. Our model considers relative capital-skill complementarities across tasks, leading to the polarization of capital and technology by task complexity, which in turn drives the polarization of job and wage growth by talent levels. Regarding optimal tax policy, the wage compression channel remains effective through the trickle-down effect of subsidizing high-wage earners and t...

摘要：We introduce novel algorithms for solving dynamic programming problems in economics on a quantum annealer, a specialized quantum computer used for combinatorial optimization. Quantum annealers begin in a superposition of all states and generate candidate global solutions in milliseconds, regardless of problem size. In contrast to existing methods, those developed in this paper (1) recover value and policy functions, (2) avoid fundamental scaling bottlenecks, and (3) are already implementable f...

摘要：Private information on car quality means the sale price reflects the average quality of cars sold, which can be lower than the average quality in the population. This difference is the lemons penalty imposed on holders of high-quality cars. We estimate the evolution of the lemons penalty through an equilibrium model of car ownership with private information using Danish linked registry data on car ownership, income, and wealth. We examine the aggregate implications and distributional consequen...

摘要：This paper develops a framework to address issues of contamination in parent-reported measures of child noncognitive skills. We estimate a dynamic model in which child and parental skills evolve jointly and leverage information provided by teachers and interviewers to deal with contamination of parent-reported measures. The model also allows us to examine the relative importance of mothers and fathers in the evolution of child skills. Our findings reveal that ignoring contamination significant...

摘要：This paper considers the theoretical, computational, and econometric properties of continuous-time dynamic discrete choice games with stochastically sequential moves, introduced by Arcidiacono, Bayer, Blevins, and Ellickson (2016). We consider identification of the rate of move arrivals, which was assumed to be known in previous work, as well as a generalized version with heterogeneous move arrival rates. We reestablish conditions for existence of a Markov perfect equilibrium in the generalize...
