Measuring Market Integration In The Global Economy

The increased level of market integration in the processed food industry through trade, foreign direct investment, and the expanded use of intellectual property rights are an observed phenomenon of the past three decades. Measurement of market integration is problematic, and the role of FDI in market integration has not been adequately taken into consideration. This study measures the growth in the market shares of multinationals in selected countries and industries to indicate the degree of market integration. We also employ a market share convergence type model to estimate whether the market shares of the multinationals and domestically owned firms in key markets have converged to some steady state during the years 1991 to 2003.
