The paper compares the definitions of Fixprice Equilibrium for productive convex economies due to Drèze, Benassy, and Malinvaud-Younès. It turns out that Drèze's (resp., Malinvaud-Younès') notion is the strictest (resp. least strict) one. The three notions are, however, equivalent under smoothness and absence of intermediate goods. They are, in particular, equivalent for the familiar fixprice model with three goods (money, labor, and output) studied among others by Barro-Grossman, Benassy and Malinvaud.  相似文献

One of the central problems in macroeconomics is the comparison of the effectiveness of various monetary and fiscal policy measures for regulating output and employment. Opinions on this issue are quite varied. This paper analyses this controversy in the framework of a non-Walrasian model with price rigidities. It studies a monetary economy where money is the sole medium of exchange in the model ‘money buys goods and goods buy money; but goods do not buy goods’. The works of Benassy, Dreze, Malinvaud and Younes are utilised for constructing a model of Keynesian unemployment equilibrium.  相似文献

Abstract

This article is an in-depth analysis of Backhouse and Boianovsky's book, Transforming Modern Macroeconomics: Exploring Disequilibrium Microfoundations, 1956–2003. I start with questioning Backhouse and Boianovsky's too broad understanding of the disequilibrium approach. Thereby they bring together theories that should be kept separate, those by Patinkin, Clower and Leijonhuvud on the one hand, and those by Barro and Grossman, Drèze and Benassy, on the other. I also substantiate my disagreement with their claim that an inner link exists between fixed price equilibrium theories and imperfect competition modelling. Finally, I put forward a few conjectures about the reason why fixed price modelling petered out.  相似文献

Micro-meso-macro   总被引:4,自引:2,他引:4  
Building on the ontology of evolutionary realism recently proposed by Dopfer and Potts (forthcoming), we develop an analytical framework for evolutionary economics with a micro-meso-macro architecture. The motive for reconception is to make clear the highly complex and emergent nature of existence and change in economic evolution. For us, the central insight is that an economic system is a population of rules, a structure of rules, and a process of rules. The economic system is a rule-system contained in what we call the meso. From the evolutionary perspective, one cannot directly sum micro into macro. Instead, we conceive of an economic system as a set of meso units, where each meso consists of a rule and its population of actualizations. The proper analytical structure of evolutionary economics is in terms of micro-meso-macro. Micro refers to the individual carriers of rules and the systems they organize, and macro consists of the population structure of systems of meso. Micro structure is between the elements of the meso, and macro structure is between meso elements. The upshot is an ontologically coherent framework for analysis of economic evolution as change in the meso domain - in the form of what we call a meso trajectory - and a way of understanding the micro-processes and macro-consequences involved. We believe that the micro-meso-macro analytical framework can greatly enhance the focus, clarity, and, ultimately, power, of evolutionary economic theory.JEL Classification: B0, C0, D0, E0, O0, P0Kurt Dopfer, John Foster, Jason Potts: We acknowledge to those who have discussed these ideas with us at the Schumpeter Society Conference, Gainesville US 2002; ECG seminars, UQ Economics, Brisbane (also students of ECON7900); Doctoral seminars at University of St. Gallen 2002, 2003; Wartensee Workshops on Evolutionary Economics 2001, 2002, 2003; the MPI in Evolutionary Economics, Jena; SPRU, University of Sussex, Brighton; and the Brisbane Club Workshop, Manchester 2002.

Summary. The paper extends the Brock-Durlauf social interactions model to richer social structures modelled with arbitrary interaction topologies and examines in detail the star, the wheel and the path. It explores Nash equilibria when agents act on the basis of expectations over, and, alternatively, actual knowledge their neighbors’ decisions. It links social interactions with econometrics of systems of simultaneous equations. The local dynamics near steady states combine spectral properties of the adjacency matrix and of the nonlinearities of reaction functions. For regular interaction topologies, adjustment exhibit relative persistence. Cyclical interaction is associated with endogenous spatial oscillations and islands of conformity.Received: 12 August 2004, Revised: 20 May 2005, JEL Classification Numbers: C35, C45, C00, D80.I am grateful to a referee and the editor for very insightful comments and suggestions, and to the National Science Foundation and the John D. and Catherine T.

Since the objective of economic policy is to change target variables in the DGP, when economic policy analysis uses an econometric model, it is important that the model delivers reliable inferences about policy responses in the DGP. This requires that the model be congruent and encompassing, and hence exogeneity, causality, cointegration, co-breaking, and invariance all play major roles. We discuss these roles in linear cointegrated VARs, prior to illustrating their importance in a bivariate model of money and interest rates in the UK over the last century.Financial support from the UK Economic and Social Research Council under grant L116251015, and the EUI Research Council grantEconometric Modelling of Economic Time Series, is gratefully acknowledged.

Will shortages of natural resources constrain economic growth? The answer seems yes, as the amount of natural resources on earth is finite. There can, however, be two excuses for this. First, the resource-saving technological progress might undo resource scarcity. Second, at the country level, countries can import resources from other countries. This paper revisits these two excuses. For technology, not all technological progress is resource-saving, and its arrival is unpredictable. For the import argument, at the global level, the world cannot make up for a shortage of natural resources by importing. Moreover, the amount of resources is difficult to forecast. To address these, I construct the open, stochastic two-sector endogenous growth model with exhaustible resources. I then analytically show that the answer is sensitive to the interaction between technology and resource shocks. In some cases, I find that higher resource uncertainty accelerates the expected growth and improves the welfare of agents.  相似文献

The article discusses the possible societal transition from information society toward biosociety. Furthermore, the impacts of this possible transition on professional and educational branches (PEBs) are examined. It is based on the study completed in Lahti Center at the Helsinki University of Technology between years 2001-2003. In the study, the most important developing key technologies were defined and their impacts on professions analysed through the application of Delphi technique. The developing key technology groups were information and communication technology, biotechnology, and material and nanotechnology. In addition, combinations of these technologies, that is, so-called fusion technologies, were also subjects for analysis. The first empirical aim was to analyse the plausibility and the timing of the so-called technological theses. The following technologies (technological theses) were deemed to be the most important ones: highly selective drugs, sensors, integrated technology, biomedical materials, photonic materials, 3G technology, intelligent materials, diagnostics, and virtual reality. The second empirical objective of the study was to analyze the professional and educational impacts of these technologies. Moreover, the article takes an experimental glance into the future through the creation and evaluation of “future professions”.  相似文献

This article holds that widespread, practical access to capital acquisition is essential for sustainable widespread economic prosperity and democracy. The founders of the U.S.A. agreed that sustainable democracy required widespread ownership of land to provide a viable earning capacity sufficient to support robust participation in democratic government. The importance of widespread land ownership to individual prosperity and sustainable democracy was supported not only by the prevailing philosophical views of property, it was also apparent to the common man and woman. Compared to Europe, America offered widespread access to land ownership, higher wages, better work conditions, cheaper staples and greater individual freedom, equal opportunity, prosperity, and political participation. This conviction that widespread access to ownership is a necessary condition for widespread prosperity and sustainable democracy continued throughout most of the nineteenth century, but today public discourse reveals virtually no trace of this once universally held opinion. This article suggests that the disappearance of this conviction can be traced to an erroneous view shaped by neoclassical economics and Keynesian economics. According to this view, (1) the disappearance of the American frontier and industrialization made the goal of widespread capital ownership either impractical or of little or no economic significance and (2) by way of technological advance, sufficient earning capacity and consumer demand to promote growth and sustain democracy can be achieved, without widespread ownership, primarily through jobs and welfare. Although differing in many respects, both mainstream schools, along with Adam Smith’s classical economics, share one common but unstated economic assumption: the broader distribution of capital acquisition (in itself) has no fundamental relationship to the fuller employment of people and capital, the broader distribution of greater individual earning capacity, and growth. Contemporary thinking, shaped by these economic schools, also tacitly assumes that widespread capital ownership is not essential for the sustainable individual earning capacity needed to support robust democracy. This erroneous “ownership-neutrality assumption” (1) contradicts both the views of America’s founders and the colonial experience, and (2) provides theoretical justification for structuring capital markets and capital acquisition transactions to unfairly and dysfunctionally favor existing owners at the expense of broader ownership distribution, more widely shared prosperity, greater efficiency, ecologically friendly growth, and a vital democracy. America’s conscientious founders would be shocked by the diminished importance of the distribution of ownership in the mainstream analysis of prices, efficiency, production, growth, and democracy. Rather than enhancing democracy, they would view the “ownership-neutrality assumption” of mainstream economics as contributing to its deterioration and corruption. They would openly search for economic analysis built on an alternate assumption more consistent with their understanding of the requisite conditions for sustainable democracy. This article advances an economic analysis that suspends the ownership-neutrality assumption, replaces it with a “broader-ownership-growth assumption,” and suggests a voluntary market strategy for substantially broadening capital ownership, enhancing individual earning capacity, and providing the widespread economic prosperity needed for robust democracy.  相似文献

This study aims at determining the major factors supporting innovative persistence based on an in-depth analysis of the internal organizational processes of the state-owned medical institution, ‘Eye Microsurgery’ Complex in Moscow. I propose a systemic approach to the study of innovation activities, which incorporates aspects of evolutionary economics, institutional analysis and dynamic capabilities theory. The study explicitly incorporates the changing external environment as a factor shaping innovation dynamics. The findings suggest that at the earliest stage of the firm's development, the interaction between the nature of the technology and the nature of the demand, the presence of prolific innovators and a certain organizational structure that supports learning, effective knowledge production and accumulation are determinant of persistence in innovation. In later periods, the availability of resources (material, financial, specialized human capital), external collaborations, specific production techniques, well-organized technological diffusion, and motivational factors are the elements providing the basis for innovative persistence. Leadership plays a crucial role in supporting innovation and organizational transformation.  相似文献
