In a market for a quality-differentiated good with heterogeneous set of consumers and a local firm facing competitive imports from abroad, we examine private and social incentives for quality innovation. For differential tariff regime, we show that both the private and social gains increase with...

Governments often subsidize poorer groups in society to ensure their access to new drugs. We analyse the optimal income‐based price subsidies in a strategic environment. We show that universal access is less likely to arise when price arbitrage prevents international price discrimination. When...

This paper investigates how devaluation by a small open economy affects its export quality when higher quality requires more of skilled labour and capital; and the ramifications of such quality changes on employment of unskilled labour and real income. In a competitive general equilibrium...
