July 2015What do Exporters Know?
with Eduardo Morales: w21351
Much of the variation in international trade volume is driven by firms' extensive margin decision to participate in export markets. To understand this decision and predict the sensitivity of export flows to changes in trade costs, we estimate a standard model of firms' export participation. In choosing whether to export, firms weigh the fixed costs of exporting against the forecasted profits from serving a foreign market. We show that the estimated parameters and counterfactual predictions from the model depend heavily on how the researcher specifies firms' expectations over these profits. We therefore develop a novel moment inequality approach with weaker assumptions on firms' expectations. Our approach introduces a new set of moment inequalities --odds-based inequalities-- and applies th...
January 2015The Impact of Market Size and Composition on Health Insurance Premiums: Evidence from the First Year of the ACA
with Mark Duggan, Joseph Orsini, Pietro Tebaldi: w20907
Under the Affordable Care Act, individual states have discretion in how they define coverage regions, within which insurers must charge the same premium to buyers of the same age, family structure, and smoking status. We exploit variation in these definitions to investigate whether the size of the coverage region affects outcomes in the ACA marketplaces. We find large consequences for small and rural markets. When states combine small counties with neighboring urban areas into a single region, the included rural markets see .6 to .8 more active insurers, on average, and savings in annual premiums of between $200 and $300.
September 2013Accounting for Expectational and Structural Error in Binary Choice Problems: A Moment Inequality Approach
with Eduardo Morales: w19486
Many economic decisions involve a binary choice - for example, when consumers decide to purchase a good or when firms decide to enter a new market. In such settings, agents' choices often depend on imperfect expectations of the future payoffs from their decision (expectational error) as well as factors that the econometrician does not observe (structural error). In this paper, we show that expectational error, under an assumption of rational expectations, is a source of classical measurement error, and we propose a novel moment inequality estimator that accounts for both expectational error and structural error in a binary choice model. With simulated data and Chilean firm-level customs data, we illustrate the identifying power of our inequalities and show the biases that arise when one ig...
