Featuring an original introduction by the editors, this important collection of essays explores the main issues surrounding the regulation of the environment. The expert contributors illustrate that regulating the environment in the UK is conceptually complex, involves a diverse range of institutions, techniques and methodologies and crosses geographical and national boundaries. In the USA it is more formalised, juridical, adversarial and formally dependent upon legal rules. The articles highlight the fact that despite differences in the UK and the USA's regulatory styles, environmental regulation today has much in common with both traditions.
"The discrete choice approach provides an ideal framework for describing the demands for differentiated products and can be used for studying most product differentiation models in the literature. By introducing extra dimensions of product heterogeneity, the framework also provides richer models of firm location and product selection."--BOOK JACKET.
A dynamic and competitive environment, underpinned by competition law policy, is an essential characteristic of successful market economies. To satisfy the growing demand for information on current approaches and practices in competition law policy, the project "Framework for the Design and Implementation of Competition Law-Policy" was initiated by the World Bank, with participation by OECD. This ensuing volume reflects the main issues that arise in design and implementation of competition law and policy in order to assist countries in developing an approach that suits their own needs and conditions. The views articulated in this publication suggest that the administration and enforcement of competition law policy should assign the greatest importance to fostering economic efficiency and consumer welfare.
This paper studies the macroeconomic effect and underlying firm-level transmission channels of a reduction in business entry costs. We provide novel evidence on the response of firms' entry, exit, and employment decisions. To do so, we use as a natural experiment a reform in Portugal that reduced entry time and costs. Using the staggered implementation of the policy across the Portuguese municipalities, we find that the reform increased local entry and employment by, respectively, 25% and 4.8% per year in its first four years of implementation. Moreover, around 60% of the increase in employment came from incumbent firms expanding their size, with most of the rise occurring among the most productive firms. Standard models of firm dynamics, which assume a constant elasticity of substitution, are inconsistent with the expansionary and heterogeneous response across incumbent firms. We show that in a model with heterogeneous firms and variable markups the most productive firms face a lower demand elasticity and expand their employment in response to increased entry.
