This paper applies the Phillips and Sul (2007) method to test for convergence in stock returns to an extensive dataset including monthly stock price indices for five EU countries (Germany, France, the Netherlands, Ireland and the UK) as well as the US over the period 1973-2008. We carry out the...

A cross-sectional relationship between price dispersion among Russian regions and per capita income dispersion is used to measure the degree of integration between regional commodity markets. The sequence of cross-sectional estimations for each month of the period spanning 1992 through 2000...

In the context of integrated market, a price of any product in regions depends on its demand in a national market rather than in a regional one. Applying the econometric model based on this theoretical statement, the paper assesses to degree the markets of some food products are integrated. The...

We examine the degree of natural gas market integration in Europe, North America and Japan, between the mid 1990's and 2002. The relationship between the international gas marker prices, and their relation to the oil price, are investigated through principal component analysis and Johansen...

The competitive effect of international market integration in industries with imperfect competition is of great policy interest. This paper focuses on the link between monopolization and market segmentation. It presents a model of multi-market entry deterrence with or without market commitments....

We consider the regulation of national firms in a common market. Regulators can influence the production of national firms but they incur in a positive cost of public funds. First, we show that market integration is welfare improving if and only if the efficiency gains compensate for the...

Using 25 years of monthly data on individual Japanese retail prices, we study the behavior of product-specific Law of One Price (LOP) deviations. Individual tradable products, compared with nontradables, are more likely to have different distributions of LOP deviations across cities. Their...

Prices may differ between regional markets if transport capacities are limited. We develop a new approach to determine to which extent such differences stem from limited participation in cross-border trader, i.e. lack of integration, rather than from bottlenecks. This approach considers both...
