A deranged publisher decided to produce a volume of some of my papers and asked me to write some comments. Since these amount to a summary of my views about international trade theory over the latest forty years or so, I’m giving the comments a separate alternative existence as a discussion paper.

This investigation pits Cournot oligopolists against each other in a model of quality and R&D choice. A firm gains a strategic advantage over its rival when it is able to sell in more countries due to the jointness of quality improvements across production locations. Trade barriers that restrict...

International agreements increasingly constrain the ability of governments to use trade policies whereas few constraints apply to the use of investment policies. Using a model in which a local and a foreign firm compete in the domestic market, we analyse whether the foreign firm may be forced to...

This paper identifies the effect of trade policy on market power through new data and a new identication strategy. We use a large dataset containing export values and quantities by product and destination for all exporting firms in 12 developing and emerging countries over several years, merged...

This paper sets up a model of trade, in which two countries with differing levels of technology specialize in the production of sub-stages of the global value chain. In the open economy, the technologically backward country exports intermediates in exchange for imports of a homogeneous...

This paper studies the incentives that developing countries have to protect intellectual properties rights (IPR). On the one hand, free-riding on rich countries technology reduces their investment cost in R&D. On the other hand, firm that violates IPR cannot legally export in a country that...

This paper presents a simple model of subsidies with export share requirements (ESR) in a heterogeneous firm environment. A two-country general equilibrium version of the model with a single 100% ESR is calibrated using firm-level data from the 2002 wave of the Business Environment and...

This paper studies the determinants of pricing-to-market at the firm-level, with a particular focus on the role of firm-specific and policy-induced market power. We use a large dataset containing export values and quantities by product and destination for all exporting firms in 12 developing and...

This paper evaluates the effect on firm-level export outcomes of the Cash Incentive Scheme for Exports program provided by the Government of Nepal. The analysis utilizes customs-level data for 2011-14, combined with information on the subsidy payments made to individual firms provided by the...

We build a model of tacit collusion between firms that operate in multiple markets to study the effects of trade costs. A key feature of the model is that cartel discipline is endogenous. Thus, markets that appear segmented are strategically linked via the incentive compatibility constraint....
