Over the 400 years covered by this study European grain markets became increasingly integrated as measured by the speed of adjustment back to equilibrium after a shock. Market integration smoothened local supply shocks and therefore generated price stability which can be seen as having a...

This paper argues that the appropriate standard for the analysis of commodity market integration is the transport cost adjusted law of one price. A threshold error correction model that incorporates that property is developed and applied to French wheat prices in the 19th century. This type of...

This paper looks at the gains from improved market efficiency in long-distance grain trade in the second half of the 19th century when violations of the law of one price were reduced due to improved information transmission. Two markets, a major export centre, Chicago, and a major importer,...

The essential issue addressed in this paper is whether inefficient spatial arbitrage has significant welfare effects. The paper looks at the gains from improved market efficiency in transatlantic grain trade in the period 1855-1895. It shows that there is a law of one price equilibrium but that...

We investigate the costs of transportation regulation using the example of agricultural markets in the United States. Using a large database of prices by state of agricultural commodities, we find that the coefficient of variation (as a measure of market integration between states) falls for...

This paper argues that the conventional view which sees international transport costs reductions as the major force in price convergence cannot be upheld when the period under scrutiny is extended to the last two centuries. Domestic transport costs fell for land-locked regions while real...

This paper challenges the widely held view that sharply falling real transport costs closed the transatlantic gap in grain prices in the second half of the 19th century. Several new results emerge from an analysis of a new data set of weekly wheat prices and freight costs from New York to UK...
