After many years of an impasse in attempts to introduce Regulatory Impact Assessment to Greece the Greek Prime Minister announced in July of 2006 the introduction of a very ambitious Integrated Impact Assessment on the economy, the society and the environment. The model presented was at the same...

Regulations aimed at curbing the entry of large retail stores have been introduced in many countries to protect independent retailers. Analyzing a planning reform launched in the United Kingdom in the 1990s, I show that independent retailers were actually harmed by the creation of entry barriers...

The authors examine the role of differentiation strategies for entry behavior in markets for local telecommunication services in the late 1990s. Whereas the prior literature has used models of interaction among homogenous firms, this research is motivated by the claim of entrants that they...

The transition of Hong Kong's main economic activities from manufacturing to services is accompanied by gradual changes in the regulatory regimes for monopolies. The local telecommunication services industry has been liberalized, deregulation of public transport is taking shape, and the schemes...

This paper develops and simulates a dynamic model of strategic telecom competition. The goal is to understand how regulatory policy, particularly relative to lease charges for local network elements, affects telecom competition, investment, retail prices, and consumer welfare. The model assumes...

With increasing frequency, generic drug manufacturers in the United States are able to challenge the monopoly status of patent-protected drugs even before their patents expire. The legal foundation for these challenges is found in Paragraph IV of the Hatch-Waxman Act. If successful, these...

We study the entry and exit of firms across U.S. industries over the past 40 years. The elasticity of entry with respect to Tobin’s Q was positive and significant until the late 1990s but declined to zero afterwards. Standard macroeconomic models suggest two potential explanations: rising...

Recent research has suggested that the reduction of entry regulation can promote firm entry and job creation, but little is known about the quality of firms and jobs created through these reforms. To shed light on this question, we employ data from Portugal, a country which implemented one of...
