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.

We propose that analysis of purchasing power parity (PPP) and the law of one price (LOOP) should explicitly take into account the possibility of ‘commodity points’ – thresholds delineating a region of no central tendency among relative prices, possibly due to lack of perfect arbitrage in...

We examine the returns from owning cows and buffaloes in rural India. We estimate that when valuing labor at market wages, households earn large, negative average returns from holding cows and buffaloes, at negative 64% and negative 39% respectively. This puzzle is mostly explained if we value...

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...

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 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...

This paper reports panel gravity estimates of aggregate bilateral trade for 130 countries over the period 1962-96 in which the coefficient of distance is allowed to change over time. In a standard specification, in which transport costs are proxied only, it is found paradoxically that the...

This Paper uses bilateral trade data for OECD countries at the 3-digit industry level to investigate the geography of intra-industry trade (IIT). IIT diminishes with distance and much of the existing empirical literature suggests that this is an inherent characteristic of such trade, arguing...
