The New Keynesian Phillips curve explains inflation dynamics as being driven by current and expected future real marginal costs. In competitive labour markets, the labour share can serve as a proxy for the latter. In this paper, we study the role of real marginal cost components implied by...

The New Keynesian Phillips Curve is at the centre of two raging empirical debates. First, how can purely forward looking pricing account for the observed persistence in aggregate inflation. Second, price-setting responds to movements in marginal costs, which should therefore be the driving force...

We study the effects of a decrease in trade costs on the spatial distribution of industry in a multi-regional economy, when a rise in the regional population of workers generates higher urban costs. When the number of cities is unaffected by falling trade costs, small cities become smaller for...

Theory is divided on whether falling transport costs lead to more or less spatial concentration of economic activity. Using US county-level data we find that aggregate employment became more concentrated between 1972-92. This aggregate picture hides important differences between sectors though....

This paper investigates how the measures of genetic distance between populations, which have been used in anthropology and historical linguistics, can be used in economics. What does the correlation between genetic distance and economic variables mean? Using the measure of genetic distance, a...

While transport costs have fallen, the empirical evidence also points at rising total trade costs. In a model of industry location with endogenous transaction costs, we show how and under which conditions a decline in transport costs can lead to an increase in the total cost of trade.

There is a large consensus among international institutions and national governments to favor urban-containment policies - the compact city - as a way to improve the ecological performance of the urban system. This approach overlooks a fundamental fact: what matters for the ecological outcome of...

We provide evidence for the effects of changes in transport costs, international trade exposure, and input-output linkages on the geographical concentration of Canadian manufacturing industries. Increasing transport costs, stronger import competition, and the spreading out of upstream suppliers...

We estimate the effect of interstate highways on the level and composition of trade for us cities. Highways within cities have a large effect on the weight of city exports with an elasticity of approximately 0.5. We find little effect of highways on the total value of exports. Consistent with...

Peaks and troughs in the spatial distributions of population, employment and wealth are a universal phenomenon in search of a general theory. Such spatial imbalances have two possible explanations. In the first, uneven economic development can be seen as the result of the uneven distribution of...
