This paper introduces endogenous and directed technical change in a growth model with environmental constraints. A unique final good is produced by combining inputs from two sectors. One of these sectors uses "dirty" machines and thus creates environmental degradation. Research can be directed...

African societies exported more slaves in colder years. Lower temperatures reduced mortality and raised agricultural yields, lowering slave supply costs. Our results help explain African participation in the slave trade, which predicts adverse outcomes today. We use an annual panel of African...

This paper builds a two-country (North, South), two-sector (polluting, nonpolluting) trade model with directed technical change, examining whether unilateral environmental policies can ensure sustainable growth. The polluting good is produced with a clean and a dirty input. I show that a...

A structural reform of the Icelandic fishing industry which created the conditions for fair and free trade in fishing permits in Icelandic waters could conceivably remove the main current obstacle to EC membership for Iceland. This reform would grant other EC nations formal access to the market...

The current Paper addresses the relationship between trade and endogenous pollution levels. The main focus is quite different from the previous literature. The mechanism linking pollution and trade is that trade provides the home government with a credible threat that helps motivate domestic...

This paper reviews the empirical evidence on the relationship between economic output and various dimensions of air and water quality. Pollution may rise with growth, because an increased scale of economic activity means more emissions, ceteris paribus. Economic growth may be associated with a...
