This innovative book takes seriously the ordinary activities of entrepreneurship and maps out new pathways for scholars to understand the nature, properties, and implications of studying practices for entrepreneurship studies. Entrepreneurship is neither an art nor a science, but a bundle of practices, as Peter Drucker once observed. Curiously however, academic research on entrepreneurship mostly abstracts away from practical activity. In contrast, Entrepreneurship As Practice takes ordinary activities of entrepreneurship seriously by mapping out new pathways for scholars to consider the everyday practices through which entrepreneurship occurs. Each chapter draws on contemporary theories of practice to illuminate the nature, properties, and implications of studying the practices of entrepreneurship. The chapters in this book were originally published as a special issue of the journal Entrepreneurship & Regional Development.
A theoretical assessment of the Rational Expectations Hypothesis through subjecting a collection of economic models to an "eductive stability" test. The rational expectations hypothesis (REH) dominates economic modeling in areas ranging from monetary theory, macroeconomics, and general equilibrium to finance. In this book, Roger Guesnerie continues the critical analysis of the REH begun in his Assessing Rational Expectations: Sunspot Multiplicity and Economic Fluctuations, which dealt with the questions raised by multiplicity and its implications for a theory of endogenous fluctuations. This second volume emphasizes "eductive" learning: relying on careful reasoning, agents must deduce what other agents guess, a process that differs from the standard evolutionary learning experience in which agents make decisions about the future based on past experiences. A broad "eductive" stability test is proposed that includes common knowledge and results in a unique "rationalizable expectations equilibrium." This test provides the basis for Guesnerie's theoretical assessment of the plausibility of the REH's expectational coordination, emphasizing, for different categories of economic models, conditions for the REH's success or failure. Guesnerie begins by presenting the concepts and methods of the eductive stability analysis in selected partial equilibrium models. He then explores to what extent general equilibrium strategic complementarities interfere with partial equilibrium considerations in the formation of stable expectations. Guesnerie next examines two issues relating to eductive stability in financial market models, speculation and asymmetric price information. The dynamic settings of an infinite horizon model are then taken up, and particular standard and generalized saddle-path solutions are scrutinized. Guesnerie concludes with a review of general questions and some "cautious" remarks on the policy implications of his analysis.
Entrepreneurship is undoubtedly a social process and creating a firm requires both the mobilization of social networks and the use of social capital. This book addresses the gap that exists between the need to take these factors into consideration and the understanding of how network relationships are developed and transformed across the venturing process.
Abstract: Bourguignon, Ferreira, and Leite develop a microeconometric method to account for differences across distributions of household income. Going beyond the determination of earnings in labor markets, they also estimate statistical models for occupational choice and for conditional distributions of education, fertility, and nonlabor incomes. The authors import combinations of estimated parameters from these models to simulate counterfactual income distributions. This allows them to decompose differences between functionals of two income distributions (such as inequality or poverty measures) into shares because of differences in the structure of labor market returns (price effects), differences in the occupational structure, and differences in the underlying distribution of assets (endowment effects). The authors apply the method to the differences between the Brazilian income distribution and those of Mexico and the United States, and find that most of Brazil's excess income inequality is due to underlying inequalities in the distribution of two key endowments: access to education and to sources of nonlabor income, mainly pensions.

Broad and diverse ranges of activities are conducted within and by organized groups of individuals, including political, economic and social activities. These activities have become a subject of intense interest in economics and game theory. Some of the topics investigated in this 2005 collection are models of networks of power and privilege, trade networks, co-authorship networks, buyer-seller networks with differentiated products, and networks of medical innovation and the adaptation of new information. Other topics are social norms on punctuality, clubs and the provision of club goods and public goods, research and development and collusive alliances among corporations, and international alliances and trading agreements. While relatively recent, the literature on game theoretic studies of group formation in economics is already vast. This volume provides an introduction to this important literature on game-theoretic treatments of situations with networks, clubs, and coalitions, including some applications.

Publisher Description
This book investigates the way in which tax systems affect economic efficiency and the distribution of welfare. It examines within a unified framework questions that are usually treated in different areas of the literature: institutional economics, positive economics, normative economics, and political economics. It adheres to the rigorous standards of pure theory while paying careful attention to the policy relevance of the arguments. Tax systems are viewed as information extracting devices that generate sets of equilibria of complex geometry. A tax reform methodology is proposed that sheds light on optimal taxes. Social conflicts in the determination of taxes are shown to have effects on social cohesion.
This indispensable Handbook offers a fresh look at entrepreneurship research, addressing what we already know, and what we still need to know, in the field. Over the course of 17 chapters, a collaboration of 24 highly-regarded researchers, expe
