We study and endogenous growth model where a profit-motivated R&D sector coexists with the introduction of free blueprints invented by philanthropists. These goods are priced at marginal cost, contrary to proprietary ones, which are produced by a monopoly owned by the inventor. We show that...

This paper examines the optimality of export subsidies in oligopolistic markets, when home and foreign firms have different costs and there is an opportunity cost to public funds. Subsidies are found to be optimal only for surprisingly low values of the shadow price of government funds, and if...

In this paper we consider the case for subsidies towards firms which generate R&D spillovers in open economies. We show that in the presence of strategic behaviour by firms many expected results are overturned. Local R&D spillovers to other domestic firms may justify an R&D tax rather than a...

This paper explores the links between international trade theory and the practice of trade and industrial policy in open economies, with special attention to three areas where theoretical lessons have been misunderstood in policy debates. It argues that the ‘concertina rule’ for tariff...

The incorporation of details of industrial organisation into the study of international trade has been the subject of a fast growing recent literature which is surveyed in this paper. Whereas the conventional theory of trade deals almost exclusively with perfect competition and non-increasing...

Muhammad Ali, who ruled Egypt between 1805 and 1849, intervened in Egyptian markets in an attempt to foster industrialization, especially between 1812 and 1840. Like a modern marketing board, the state purchased agricultural commodities (cotton, wheat) at low prices and sold them on world...

The paper provides a first structural-estimation-based assessment of an influential hypothesis that export pioneers are too few relative to social optimum due to knowledge spillover in new market explorations. Such market failure requires two inequalities to hold simultaneously: the discovery...

Although the global economy has begun to recover from the 2008-2011 financial crisis, challenges to the world trading system have increased. Several trends are taking public policies further away from the core WTO disciplines of non-discrimination, namely MFN and national treatment. This has...

We estimate the effect on economic development of China's industrial policy, in particular, the establishment of Special Economic Zones (SEZ). We use data from a panel of 276 Chinese cities and prefectures from 1988 to 2010. Our difference-in-difference estimator exploits the variation in the...

Business support policies designed to raise productivity and employment are common worldwide, but rigorous micro-econometric evaluation of their causal effects is rare. We exploit multiple changes in the area-specific eligibility criteria for a major program to support manufacturing jobs...
