Spatial quality choice is introduced, where consumers are horizontally differentiated by taste and firms vertically differentiated by quality location, within an equilibrium model of duopoly competition characterized by asymmetric fixed and variable costs. Firms choose quality location followed by prices but then may vertically re-locate their quality offerings based on changing horizontal consumer taste. A monopolistic equilibrium solution arises with firms achieving positive economic profits through price-quality markups exceeding marginal costs. Under strict inequality conditions, each firm acts as a monopolistic competitor within a range of quality choices governed by multiple relative differentiation outcomes. On the other hand, vertical re-location exhibits a resistance to change on the part of vertically located firms such that firms dislike quality re-location and prefer stable preferences in quality. Such resistance to change is overcome by firms re-locating their quality offerings to maximize monopolistic brand-space gains. It is argued that more horizontal differentiation may force more product differentiation by vertical quality relocation. A relative change in quality preferences may result in wider quality spreads in the market through vertical quality re-locations, even though the resistance to change arguments may still hold good.

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.

This book provides a comprehensive, up-to-date, and expert synthesis of location theory. What are the impacts of a firm’s geographic location on the locations of customers, suppliers, and competitors in a market economy? How, when, and why does this result in the clustering of firms in space? When and how is society made better or worse off as a result? This book uses dozens of locational models to address aspects of these three questions. Classical location problems considered include Greenhut-Manne, Hitchcock-Koopmans, and Weber-Launhardt. The book reinterprets competitive location theory, focusing on the linkages between Walrasian price equilibrium and the localization of firms. It also demonstrates that competitive location theory offers diverse ideas about the nature of market equilibrium in geographic space and its implications for a broad range of public policies, including free trade, industrial policy, regional development, and investment in infrastructure. With an extensive bibliography and fresh, interdisciplinary approach, the book will be an invaluable reference for academics and researchers with an interest in regional science, economic geography, and urban planning, as well as policy advisors, urban planners, and consultants.

Avinash Dixit and Joseph Stiglitz revolutionized the modelling of imperfectly competitive markets and launched "the second monopolistic competition revolution". Experts in the areas of macroeconomics, international trade theory, economic geography, and international growth theory examine the success of the second revolution in this collection of papers. They reveal what appears to be "missing" and look forward to the next step in the modelling of imperfectly competitive markets. The text includes a comprehensive survey of the two monopolistic competition revolutions, and previously unpublished working papers by Dixit and Stiglitz that led to their famous 1977 paper.

Thorough and authoritative, Regional and Urban Economics and Economic Development: Theory and Methods provides students with a sound approach to analyzing the economic progress of a region or urban area. The textbook is divided into four sections for ease of reference. The first section, Market Areas and Firm Location Analysis introduces spatial economics and location theory, while the next section, Regional Growth and Development analyzes regional growth and development models and policy. Introducing the foundations of urban economics, Urban Land Use and Urban Form examines land rent, land use patterns, and the effects of attempts to control land uses. The final section, Urban Problems and Policy, investigates local public finance and introduces the policy analysis involved in countering urban problems. Addressing these topics from the perspectives of how they affect the population at large and how they become established within public policy, Regional and Urban Economics and Economic Development: Theory and Methods provides students with an essential foundation not only to understand but also to contemplate the dynamics of varying economic factors as they relate to an area's growth.
