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...

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...

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...

We study the impact of local taxation on the location and growth of firms. Our empirical methodology pairs establishments across jurisdictional boundaries to estimate the impact of taxation. Our approach improves on existing work as it corrects for unobserved establishment heterogeneity, for...

We use variation in oil output among Brazilian municipalities to investigate the effects of resource windfalls. We find muted effects of oil through market channels: offshore oil has no effect on municipal non-oil GDP or its composition, while onshore oil has only modest effects on non-oil GDP...

This paper investigates the economic impact of the government's proposed new UK R&D tax credit. We measure the benefit of the credit by the effect on value added in the short and long?run. This is simulated from existing econometric estimates of the tax?price elasticity of R&D and the effect of...

A reduction in income tax rates generates substantial dynamic responses within the framework of the standard neoclassical growth model. The short-run revenue loss after an income tax cut is partly - or, depending on parameter values, even completely - offset by growth in the long-run, due to the...

A main activity of the state is to redistribute resources. Models of the political process generally predict that a rise in inequality will lead to more redistribution. This paper shows that, for the UK in the period 1983-2004, a plausibly exogenous rise in income inequality has not been...

This paper presents a political economy model of inflation as a result of social conflict. Agents are heterogeneous in terms of income. Agents' income levels determine their ability to hedge against the effects of inflation. The interaction of heterogeneous cash holdings and preferences over...

It has been suggested in the literature that taxes and subsidies play an important role in explaining the differences in working hours across countries. In this paper I test whether public programmes for family support play a role in explaining this variation. I analyse two types of policies:...
