This article analyzes the effect of public policy intervention in the production of health capital on fertility, private investment in children's health and education and human capital accumulation. I have used a growth model with endogenous fertility, in which the usual parental trade-off...

We address the trade effect of restrictive product standards on the margins of trade, by matching a detailed panel of French firm exports with a new database compiling the list of Sanitary and Phyto-Sanitary regulatory measures that have been raised as a concern in dedicated committees of the...

Recent quantitative trade models treat import tariffs as pure cost shifters so that their effects are similar to iceberg trade costs. We introduce revenue-generating import tariffs, which act as demand shifters, into the framework of Arkolakis, Costinot and Rodriguez-Clare (2012), and generalize...

Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known - and traditionally presumed exogenous – “trade-cost elasticity” plays a central role in computing general equilibrium trade-flow...

We study the equilibrium determinants of firm-level heterogeneity in a model in which firms can affect the variance of their productivity draws at the entry stage and explore the implications in closed and open economy. By allowing firms to choose the size of their investment in innovation...

Increasing wage inequality between similar workers plays an important role for overall inequality trends in industrialized societies. To analyze this pattern, we incorporate directed labor market search into a dynamic model of international trade with heterogeneous firms and homogeneous workers....

This paper introduces quality innovations with endogenous sunk costs in a heterogeneous firm model of international trade and derives implications for the gravity equation. The model predicts that the effect of fixed costs on exports and on the share of exporters is lower in industries with a...

According to conventional wisdom, multinational firms undertake vertical FDI in order to take advantage of cross-border factor cost differences and source the inputs from abroad at better terms. Recent empirical findings though document that this is not always the case. We provide theoretical...

In their famous paper on the “Big Push”, Murphy, Shleifer, and Vishny (1989) show how the combination of increasing returns to scale at the firm level and pecuniary externalities can give rise to a poverty trap, thereby formalising an old idea due to Rosenstein-Rodan (1943). We develop in...
