Before 1970s, IO predominantly follows the paradigm of “structure-conduct-performance”, or often called the Harvard tradition, after Professor Joe Bain. The basic idea is that market structure determines how ...rms behave, which in turn determines the performance of the market. The research methodology is mainly empirical: running regressions on variables of market structures to see their e¤ect...

This thesis is composed by three different studies on oligopolies. The first chapter is on oligopolies with perfect complements; the second chapter studies oligopolies with positive network effects and incompatible networks, and the last one deals with a polluting duopoly subject to environmental regulation. Specifically, the first chapter provides a thorough characterization of the properties ...

The chapter starts with an elementary introduction to the three basic oligopoly theories, associated with the names of Cournot, Bertrand and Stackelberg. These theories are then covered in depth, including generalizations, extensions to entry, exit, and capacity choice...

The Online Data Appendix is organized in two parts. Part I provides a detailed description of the steps involved in constructing the restricted sample of international travel and trade flows used in the empirical part of the paper. The focus is primarily on the treatments applied to the original air travel dataset DataBank 1B (DB1B) Passenger Origin and Destination Survey, provided by the US De...

The shape and evolution of firm size distribution has been studied in industrial organization and labor economics. The standard hypothesis of Gibrat’s law of proportionate effect posits that the rate of firm growth is size-independent. We test Gibrat’s law using a new empirical methodology and considering the underinvestigated Brazilian case. Quantile regression is used to estimate the evolutio...

Industrial symbiosis (IS) has been used to describe the physical exchange and shared management of input and output materials by geographically proximate firms. Firms that engage in IS are said to belong to an industrial ecosystem. Symbiosis has been found to be motivated by economic considerations, such as lowering costs for waste disposal, as well as by environmental ones, such as accessing l...
