This paper empirically establishes the significant roles of transport costs in price dispersions across regions. We identify and estimate the iceberg-type distance-elastic transport costs as a parameter of a structural model of cross-regional price differentials featuring product delivery...

This study investigates the effect of distance on price differentials across regions. To identify the distance effect, we need to incorporate producer heterogeneity and pricing-to-market behavior. Because geographic barriers alter the threshold levels of productivity to set a positive price...

This study examines the effect of mergers and acquisitions (M&A) on productivity. According to the literature, the effect of a merger or acquisition on an acquiring firm's productivity is small. We examine the extent to which self-selection of M&A contributes to the weak M&A effect. Using data...
