This paper explores the impact of trade on growth when firms are heterogeneous. We find that greater openness produces anti-and pro-growth effects. The Melitz-model selection effects raises the expected cost of introducing a new variety and this tends to slow the rate of new-variety introduction...

Formal analysis of the political economy of trade policy was substantially redirected by the appearance of Gene Grossman and Elhanan Helpman’s 1994 paper, “Protection for Sale”. Before that article a fairly wide range of approaches were favoured by various authors on various issues, but...

Governments frequently intervene to support domestic industries, but a surprising amount of this support goes to ailing sectors. We explain this with a lobbying model that allows for entry and sunk costs. Specifically, policy is influenced by pressure groups that incur lobbying expenses to...

The paper decomposes a geographical concentration index to examine the temporal scope of a spillover, which is the period of time over which one firm’s activity directly affects the location of other firms’ activities. Natural advantages are fixed over reasonably long time periods, but if...

Globalisation is a phenomenon that is said to have radically changed the international economy. It is said to have radically limited the power of national governments, particular in the field of taxation, in a world of highly mobile capital and flexible transnational corporations. To explore the...

This paper shows that smoking intensity, i.e. the amount of nicotine extracted per cigarette smoked, responds to changes in excise taxes and tobacco prices. We exploit NHANES data covering the period 1988 to 2006 across many US states. Moreover, using panel data from the Coronary Artery Risk...

This paper exploits data on the pattern of violence across regions and over time to estimate the impact of the peace process in Northern Ireland on house prices. We begin with a linear model that estimates the average treatment effect of a conflictrelated killing on house prices - showing a...

The study of welfare capitalism is concerned with a founding question of political economy, namely how capitalism and democracy can be combined. Ever since the publication of Esping-Andersen’s Three Worlds of Welfare Capitalism in 1990, the answer was sought in identifying ideal types of...

We report on an on-going project, which asks a number of questions relevant to the study of state capacity. What are the main economic and political determinants of the state’s capacity to raise revenue and support private markets? How do risks of violent conflict affect the incentives to...

One of the key goals of political economy is to understand how institutional arrangements shape policy outcomes. This paper studies a comparatively neglected aspect of this - the forces that shape heterogeneous performance of autocracies. The paper develops a simple theoretical model of...
