This paper extends a recent class of quantitative models of international trade to incorporate factor mobility within countries. We present a model-based decomposition of the variance of economic activity into the contributions of locational fundamentals, market access and their covariance. We...

This paper presents a model of international trade that features heterogeneous firms, relativeendowment differences across countries, and consumer taste for variety. The paper demonstrates thatfirm reactions to trade liberalization generate endogenous Ricardian productivity responses at...

Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: the standard practice of interpreting the parameters of log-linearized models estimated by ordinary least squares as elasticities can be highly misleading...

We draw attention to the role of economic geography in explaining important cross-sectional facts which are difficult to account for in existing models of industrialization. By construction, closed-economy models that stress the role of local demand in generating sufficient expenditure on...

This paper derives a micro-founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and substitution patterns across goods. In contrast to standard CES-based gravity equations, trade is more sensitive to trade costs if the exporting...

The paper explores the determinants of industry location across interwar Poland. After more than 120 years ofpolitical and economic separation, Poland was reunified at the end of 1918. In consequence, its industry facedmassive structural changes: the removal of internal tariff barriers and...

The recession of 2008-09 inflicted a larger cumulative loss of UK output than any of the previous post-war recessions, yet there has been a relatively low loss of employment, at least so far. Paul Gregg and Jonathan Wadsworth look for an explanation.

This paper assesses the impact of the National Minimum Wage (NMW) on employment and inequality in the UK over the decade since its introduction in 1999. Identification is facilitated by using variation in the bite of the NMW across local labour markets and the different sized year on year up...

GDP per worker fell for the five years after 2008 which is unprecedented in post war UK history. In this paper we argue that "capital shallowing" (i.e. the fall in the capital-labour ratio) could be the main reason for this. This is likely to have occurred due to changes in factor prices: a...

The recession of 2008-2009 inflicted a larger cumulative loss of UK output than any of the other post-war recessions. Nevertheless, employment rates remained higher than might have been expected given the experience of previous recessions. The main reasons for this appear to be a combination of...
