Empirical evidence of the impact of borders on international trade flows using the gravity equation approach abounds. This paper examines the empirical relevance of state borders in U.S. interstate trade for various specifications of the gravity equation. We find a large and economically...

This paper develops a two-country dynamic general equilibrium model with endogenous growth to analyze the effects of international trade on steady state growth. The two countries differ both in preferences and in technologies. We show first, that both countries cannot simultaneously experience...

In this paper we examine the empirical relevance of three prominent endogenous protection models. Is protection for sale, or do altruistic policy makers worry about political support? We find strong evidence that protection is indeed "for sale". The important new result is, however, that not...

Do contributions levels matter for endogenous protection or is the existence of a lobby sufficient? Are lobbies’ net benefits from protection identical to their contribution levels, or does the level of protection simply reflect contribution levels of supporters and opponents? We estimate the...

This paper provides a novel explanation forthe formation of protectionist lobby groupsin imperfectly competitive sectors. Thelevel of collusion is shown to be a crucialdeterminant of the ability of firms tosustain lobbying. We show that greatercollusion reduces firm contributionsto tariff...

We consider growth and welfare effects of lifetime-uncertainty in an economy with human capital-led endogenous growth. We argue that lifetime uncertainty reduces private incentives to invest in both physical and human capital. Using an overlapping generations framework with finite-lived...
