This paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we … present on the importance of product switching by U.S. manufacturers. Two-thirds of continuing firms change their product mix … theoretical model incorporates heterogeneous firms, heterogeneous products, and ongoing entry and exit. In equilibrium, firm …

This paper examines the frequency, pervasiveness and determinants of product switching among U.S. manufacturing firms …. We find that two-thirds of firms alter their mix of five-digit SIC products every five years, that one-third of the … increase in real U.S. manufacturing shipments between 1972 and 1997 is due to the net adding and dropping of products by …

Firms' decisions about which goods to produce are often made at a more disaggregate level than the data observed by … firms endogenously self-selecting into heterogeneous products. We characterize the bias introduced by unobserved variation … in product mix across firms, and the implications of this bias for identifying firm and industry responses to exogenous …

This paper investigates how corrupt public officials and firms adjust to policy reforms that change opportunities for … extraction. I provide suggestive evidence on how these displacement effects can be economically costly given that firms respond … firms increase imports in response to the tariff reduction, firms experiencing an increase in the probability of paying a …

This is however partially offset by the displacement of corruption into other firms of … bribe extraction that led to a 70% increase in average bribes per transaction and a shift from collusive to coercive firms … firms respond to changes in bribe patterns by adjusting their sourcing decisions. Firms experiencing an increase in the …

We estimate the impact of a carbon tax on manufacturing plants using panel data from the UK production census. Our …

We estimate a structural model of heterogeneous multiproduct firms to examine the sources of firm heterogeneity … substitution within and between firms, and use the estimated model to recover unobserved qualities, marginal costs and markups. We … firms are well approximated by the monopolistic competition benchmark of constant markups, but the largest firms that …
