This volume highlights the use of structural methods by applying them to a large number of widely different contexts. The essays draw on data from several countries such as Colombia, India, and the U.S. and develop empirical models that are applied to a wide range of policy issues. Some of these issues relate to the infant computer industry in India in the 1980s, the cement industry in the US, factors underlying the ownership of blast furnaces in India in the 1990s, entry decisions of producers in export markets, and even a down-to-earth issue such as the behavior of pedestrians attempting to cross a stream of traffic at signalized intersections.
