Abstract. We develop a model of firms’ growth in which the tax and credit environments act as selection mechanisms. Such a model, parameterized and validated using a variety of data restrictions, can rationalize observations about input choices and size patterns typical of many developing countries. Using counterfactual experiments, we show that firms’ optimal responses to the tax environment are effective in reducing efficiency losses. As a consequence, tax distortions only account for 13% of the gap in output per worker between an undistorted economy and the benchmark. Credit constraints account for 44% of this gap. However, the interaction between the cost of capital and credit constraints appears to be the most important source of misallocation and can explain up to 85% of the difference in output per worker between the benchmark and first-best.

Giovanni Gallipoli is a professor at UBC in Vancouver. Giovanni's research focuses on the origins and consequences of economic inequality with a focus on how heterogeneity shapes individual behaviors and aggregate economic outcomes. Giovanni has worked on a variety of topics, including the equilibrium effects of policies that promote skill formation; the link between skill heterogeneity and a country's comparative advantage; the influence of families on long-term outcomes such as labor supply and consumption; intergenerational mobility and the linkages between parental heterogeneity and inequality; and how firm-level differences contribute to variation in workers’ skill returns. Giovanni is a recipient of the Killam Research Award, the FEEM Award, and the Young Economist Award of the European Economic Association. He is a CEPR research fellow as well as a former Fulbright Scholar and Weatherhall fellow. He serves as a member of the external board of overseers of the Panel Study of Income Dynamics (PSID) and as an associate editor of the Journal of Political Economy. Giovanni is an alumnus of the Sant'Anna School of Advanced Studies and the University of Pisa in Italy. He received his Ph.D. in Economics from University College London in the UK.
