In this paper we consider conditions under which the estimation of a log-linearized Euler equation for consumption yields consistent estimates of the preference parameters. When utility is isoelastic and a sample covering a long time period is available, consistent estimates are obtained from the log-linearized Euler equation when the innovations to the conditional variance of consumption growth are uncorrelated with the instruments typically used in estimation. We perform a Monte Carlo experiment, consisting in solving and simulating a simple life cycle model under uncertainty, and show that in most situations, the estimates obtained from the log-linearized equation are not systematically biased. This is true even when we introduce heteroskedasticity in the process generating income. The only exception is when discount rates are very high (e.g. 47% per year). This problem arises because consumers are nearly always close to the maximum borrowing limit: the estimation bias is unrelated to the linearization and estimates using non-linear GMM are as bad. Across all our situations, estimation using a log-linearized Euler equation does better than nonlinear GMM. Finally, we plot life cycle profiles for the variance of consumption growth, which, except when the discount factor is very high, is remarkably flat. This implies that claims that demographic variables in log-linearized Euler equations capture changes in the variance of consumption growth are unwarranted.  相似文献

This survey covers the recent literature on inter-firm networks as far as they have implications for innovation and technological change. The studies are classified according to the direction of causality in network studies. In the literature, some studies focus on the effect of networks, while others on the origins and formation of networks. These are represented as a circular flow diagram of network research. Circular diagram includes three themes of analysis as: (1) origins of networks, (2) firm performance, (3) network structure, and shows the relationship between these themes as observed in network research. The aim of this survey is to guide researchers working on inter-firm networks about the theoretical and empirical results obtained up to now in the field and to highlight those areas which need further work.  相似文献

Neuroeconomics draws attention to motive forces that are ignored in the standard framework of economic theory. The present paper develops a conceptual approach that, similar to Pennings et al. (Journal of Bioeconomics 7: 113–127, 2005), tackles the issues at the systemic level by analyzing and modeling the brain processes that decide on behavior. It takes as the basic unit of analysis potential stimulus-response actions which—when selected—become actual behavior. The objective of these potential stimulus-response actions is to increase utility. At any moment of time, several of these potential actions compete with each other for the privilege of becoming actual behavior. This competition can be modeled on the basis of economic principles. The behavior that materializes may cover the range from the rational to the foolish, depending on which of the potential responses gathers the greatest emotional strength. The emotional strength of a potential response, in turn, is determined by the individual’s past experience and her capacity for rational action. Given that the objective is always to increase utility, it can normally be expected that the more or less rational dominates the foolish, but this need not always be the case. Which potential actions become behavior in a concrete instance is decided by a mechanism implemented by the basal ganglia, a structure in the brain serving as the action selection mechanism. The insights provided by this approach afford coherent explanations of behaviors that are not readily explicable by the standard approach of economic theory.   相似文献

I survey the literature post Ledyard (Handbook of Experimental Economics, ed. by J. Kagel, A. Roth, Chap. 2, Princeton, Princeton University Press, 1995) on three related issues in linear public goods experiments: (1) conditional cooperation; (2) the role of costly monetary punishments in sustaining cooperation and (3) the sustenance of cooperation via means other than such punishments. Many participants in laboratory public goods experiments are “conditional cooperators” whose contributions to the public good are positively correlated with their beliefs about the average group contribution. Conditional cooperators are often able to sustain high contributions to the public good through costly monetary punishment of free-riders but also by other mechanisms such as expressions of disapproval, advice giving and assortative matching.  相似文献

Introducing money into a scheme of general economic equilibrium entails manifold problems, which have emerged in many contributions to the literature. Some of these problems have been adequately addressed at the level of micro-based approaches which can be traced back to the monetary theory of Carl Menger. In this survey we shall review such issues, after which we shall attempt to illustrate the contribution to solving the problem of the origin of money offered by the literature on transaction and information costs inspired by Menger's monetary theory. (JEL: E40, E42, D83) Although this paper is the fruit of a common effort, credit for Sections 1, 2, 3, 5, 5.1, 5.2, 5.3 goes in particular to Giuseppe Mastromatteo, and for Sections 4, 4.1, 4.2, 4.3, 4.4, 6 to Luigi Ventura. The authors would like to thank the referees for most useful comments and suggestions; the usual disclaimer applies.  相似文献

In this study we compare the traditional OLS approach applied to the log-linear form of the gravity model with the Poisson Quasi Maximum Likelihood (PQML) estimation procedure applied to the non-linear multiplicative specification of the gravity model. We use the trade flows for all products, for all manufacturing products as well as for manufacturing products broken down by three-digit ISIC Rev.2 categories. We base our conclusions on the gravity model of Bergstrand (Rev Econ Stat 71(1):143--153, 1989) for disaggregate trade flows that allows us to investigate differences in factor-proportions and home-market effects at the industry level. In addition, we compare the effects of other explanatory variables such as exporter and importer total income, distance, preferential trade agreements, common border, historical ties, and common language on the volume of trade. Our main conclusion is that both estimation results as well as results of the regression mis-specification tests provide supporting evidence for the PQML estimation approach over the OLS estimation method. The paper has benefited from comments by an anonymous referee and by the participants at the following conferences: the 4th Nordic Econometrics Meeting, Tartu, Estonia, the 8th Annual Conference of the European Trade Study Group (ETSG), Vienna, Austria, the 21th Annual Congress of the European Economic Association (EEA), Vienna, Austria, the XIth Spring Meeting of Young Economists (SMYE), Sevilla, Spain, and the 5th Annual Conference of the European Economics and Finance Society (EEFS), Heraklion, Greece.  相似文献

This article analyses developments in the external sector for the Euro Area and its major competitors and quantifies the dynamic contributions of the key determinants of trade to export volume behaviour. In addition to the traditional variables affecting export volumes, price and foreign demand, an unobserved component in the form of a time-varying trend enters the export equations to capture underlying non-price competitiveness. The structural modelling approach used within an error correction framework allows isolating the different sources of trade fluctuations and to better assess the contribution of each set of variables to export flows. The findings confirm that stochastic trends are present as a result of technical change and other exogenous factors driving export flows, and that a failure to account for these trends will lead to biased estimates of long-run price elasticities.  相似文献

It is widely agreed that floating is not an appropriate exchange rate policy for most developing countries, but in a world of generalized floating the question of exchange rate policy is not resolved by deciding to peg rather than to float: it is also necessary to decide to what to peg. This is the question of the ‘optimal peg’, on which a significant literature has emerged since 1976. The present paper provides a survey of that literature. Section 2 summarizes the principal papers. Section 3 compares the objectives and rules advocated by different authors. Section 4 evaluates the alternative approaches, arguing that in general the peg should be chosen to stabilize the nominal trade-weighted effective exchange rate. Section 5 considers whether this criterion points to the SDR as a satisfactory peg.  相似文献

Economists often use Gallup Poll data on presidential performance to analyze the interaction between politics and the state of the macroeconomy. The household survey undertaken by the Survey Research Center (SRC) of the University of Michigan provides an alternative data base. The SRC asks respondents about the government's performance specifically with respect to inflation and unemployment. We compare whether the Gallup or SRC data are the more useful for estimating the public's social preference function between inflation and unemployment for the Carter, Reagan, Bush and Clinton presidencies. The estimates that use Gallup Poll data are unsatisfactory because for two of the periods the coefficients of inflation and unemployment are not well estimated and for one period there is serial correlation of the residuals. The estimates using the SRC data set are satisfactory and the results are consistent with economic theory. We conclude that a researcher using survey data to estimate the public's reaction to varying rates of inflation and unemployment should prefer the SRC series when it is available.

This paper surveys the recent literature on the effects of United States protection. Most of these studies find that tariffs provide limited benefits to protected industries but cause considerable harm to household and industrial consumers of protected goods. Most studies do, however find some terms-of-trade benefits to the United States in the present structure of protection. Also, studies of quotas find that they have become more important in recent years and that they are a major source of welfare losses for the United States. This general agreement regarding the effects of United States policy arises from papers employing different research methodologies and addressing different questions.  相似文献

This paper surveys the more abstract literature on the newly developing theory of economic systems. Works from both pure economic theory and comparative economics are discussed. The principal thesis is that, while these two literatures have developed rather independently, they share an amazingly similar framework. What is emerging is a full-fledged theory of economic systems. Emphasis is placed on the three component structures of economic systems—the information, decision-making, and incentive structures–and the normative evaluation of economic systems. J. Comp.

The aim of this article is to study the technology of the sector represented by the Spanish national post-office and telegraph service, Sociedad Estatal Correos y Telégrafos, S.A. trading as Correos, and denominated as such hereafter. Concretely, we analyse economic efficiency (technical and allocative) and scale economies of the production units (cost centres) of Correos. To do this, we employ a methodology based on an input distance function which is the dual of the cost function. Moreover, and applying duality theory, we develop an economic model to assess the effect of postal infrastructures on the operators’ costs. In order to carry out the empirical model, Bayesian econometrics is applied to estimate the parameters in the input distance function and the technical and allocative efficiency terms.  相似文献

Efficiency analysis is an important tool for evaluating firms' performance. This paper introduces a novel approach for measuring technical efficiency (TE) in the case of technologies with multiple outputs which deals with the endogeneity of outputs issue. The proposed approach uses Artificial Neural Networks (ANNs) and the method of Limited Information Maximum Likelihood (LIML). The validity of the proposed approach is illustrated by fitting it to a large US data set for all commercial banks in the 1989–2000 time span. Meanwhile, we compare the proposed approach to the single-equation Translog output distance function and the proposed approach was found to yield very satisfactory results, while dealing with the issue of the endogeneity of outputs.  相似文献
