The relevance of transport costs has increased as liberalization continues to reduce artificial barriers to trade. Countries need to adopt policies to “get closer†to global markets. Can improvements in infrastructure and regulation reduce transport costs? Is it worthwhile to implement...

This paper considers the parametric inference of a wide range of structural econometric models. The class of models considered includes those with parameter-dependent support and those derived from game-theoretic models. Inference of those models has raised some important econometric issues....

Within the independent private-values paradigm, we derive the data-generating process of the winning bid for the last unit sold at sequential English auctions when bidder valuations are draws from one of several different classes of distributions; i.e., in the presence of asymmetries. When the...
