The aim of this paper is to analyze the economic and social cohesion in the European Union. There are different factors to
explain the convergence process and besides, empirical findings are not conclusive. To the European Union, GDP per head interregional
differences have decreased for certain periods but it has remained unchanged or even increased for others periods. The second
report on the economic and social cohesion indicates that some decades are necessary to eliminate regional differences. These
differences in regional GDP are mainly explained by differences in their productive structures, degree of innovate activity,
communications structures, which depend on the relative level of transport infrastructures, and manpower qualifications. This
analysis allows us to obtain some conclusions to the economic policies and the social cohesion.
A preliminary version of this paper was presented in the 57th International Atlantic Conference, held in Lisbon, Portugal,

In this article, we show that macroeconomic time series may contain unit and fractional roots at both, at zero and at zero and at the seasonal frequencies. The importance of the root at the long run or zero frequency requires in many cases to consider this root at both, separately in an independent polynomial, and also included in the seasonal one. Several Monte Carlo experiments are conducted to examine cases when the root at the zero frequency is not appropriately considered. An empirical application based on the tests of Robinson, Peter M. “Efficient Tests of Nonstationary Hypotheses,” Journal of the American Statistical Association, 89, 1994, pp. 1420–37 is also carried out at the end of the article.The author gratefully acknowledges financial support from the Government of Navarra (“Ayudas de Formación e Investigación y Desarrollo”). 相似文献
This paper applies smooth transition models to capture the nonlinear behavior in the imports data of six major European economies and to assess whether such nonlinearities are related to business cycle asymmetries. Two classes of switch between regimes are considered: endogenously determined transition that assumes nonlinearities are generated by idiosyncratic components specific to foreign trade, and exogenous transition based on GDP growth as a more direct indicator of the cyclical state of the economy. The results support the proposition that the dynamics of imports are nonlinear. In Belgium, France, Spain, and the United Kingdom, regimes change over the business cycle, while in Germany and Italy the switch between regimes is endogenous. National characteristics play a role in defining the position of extreme regimes, the smoothness of the transition, and local dynamics within each state.Previous versions of this article have been presented at the 57th International Atlantic Economic Conference (Lisbon, Portugal, March 10–14, 2004) and at the VII Encuentro de Economía Aplicada (Vigo, Spain, June 3–5, 2004).

Current research in applied demand analysis has been addressing the twin issues of degree of non-linearity or curvature of the Engel curves and the ability to capture price effects appropriately by the demand system. Further, in addition to income and prices, the role of demographic variables like household size, composition and dynamic aspects like consumer taste & preferences are also being ’ emphasized in recent literature. Continuous efforts are being made to modify the existing models and propose new ones to incorporate the above developments. The purpose of this study is to re-examine the usefulness of the popular linear expenditure system vis-à-vis the two other flexible models viz. Nasse expenditure system, a generalization of the linear expenditure system itself, and the almost ideal demand system in the above context for India.The empirical results indicate wide variation in marginal budget shares and demand elasticities across income groups, rural-urban sectors and alternative models. The household size and consumer taste & preferences are found to be statistically significant. The results confirm the earlier findings that there are significant changes in consumer tastes away from cereals and pulses in favor of other food and nonfood commodities. The results also show that flexible models, which are theoretically superior, gave unacceptable positive price responses for some commodities and violated second order conditions of utility maximization. It is found that some ad-hoc separability restrictions are needed, thereby limiting the flexibility of the model, to get negative own-price responses in these models. But, second order conditions are still violated. The tests of nested hypotheses also confirm the need for inclusion of household size, consumer taste, income group and rural-urban dummies along with their interaction variables in the demand system.
The objective of this research work is to study the progress of research on technological uncertainties, social uncertainties and emerging markets and outline and identify the key disciplines, journals, articles and authors. For this the author studied the existing literature from the various fields in which technological uncertainties, social uncertainties and emerging markets research work have been published using ISI Web of Knowledge database. The paper finds that there is increasing research work on technological uncertainties, social uncertainties and emerging markets and the bibliographical search resulted in ninety-one documents written by one-hundred-sixty-one authors in eighty-four journals in seventy-two disciplines. The five major disciplines and their underlying journals are business and economics, agriculture, psychology, public administration, and environmental sciences and ecology accounting for majority of publications. In journals the most prolific, measured by number of articles published are Harvard Business Review, Social Science and Medicine, World Development, and Higher Education; and most influential, measured by the global citation received, are Harvard Business Review, Social Science and Medicine and Sociological Review. The top 10% of the journals are responsible for 23% of all publications but 85% of all global citations received. This highlights that despite the high, diverse and increasing number of journals; only few are dominating and shaping the research arena of technological uncertainties, social uncertainties and emerging markets. Further, in the ten most cited articles, no author appears more than once. 相似文献
This study reports results from a new series of experiments that examine the robustness of face-to-face communication as a cooperation-facilitating institution in common-pool resource settings. Results are reported from nine experiment sessions, initially designed for pedagogical purposes. The sessions were conducted between 1998 and 2007 as part of a series of summer institutes on institutional analysis and environmental change. Subjects were graduate students and professionals from diverse disciplines, representing 41 countries of residence. The participants in this study stand in sharp contrast to most previous studies, which used undergraduates who self-select into experiments by volunteering to participate. Results from these experiments substantiate earlier findings that non-binding communication can serve as an effective mechanism for solving social dilemma problems, with subjects achieving near socially efficient outcomes. 相似文献
This study presents the nonlinear relationship that exists between financial development and economic growth. This study applies
the flexible nonlinear regression model of Hamilton (Econometrica 69(3):537–573, 2001) because it imposes no specification
restrictions. Two empirical results are obtained. First, an inverted U-shaped relation between banking sector development
and economic growth is identified. Namely, the two variables are positively linked before the turning point, but negatively
linked after it. Second, a positive relationship with asymmetric √-shape between stock market development and economic growth
is found. 相似文献
We analyze the impact of leniency programs on the behavior of firms participating in illegal cartel agreements in a two-stage
repeated game model. Our approach takes into account asymmetric punishment effect and allows to discuss the design of leniency
programs in the setting with asymmetries. The main contribution of the paper is that we consider heterogeneous firms. This
heterogeneity results in additional costs in case of disclosure of the cartel, which are caused by asymmetric punishments.
Next, following current antitrust rules, we analyze effects of the strictness of leniency programs, which reflects the likelihood
of getting a complete exemption from fine even in case many firms self-report simultaneously. Our main conclusion is that
leniency programs work better for small companies, since a lower rate of law enforcement is needed in order to induce self-reporting
by smaller firms, while big firms are less likely to start a cartel in the first place given the possibility of self-reporting
in future. Finally, we analyze optimal enforcement strategies of the antitrust authority and conclude that the authority with
limited resources should implement more generous leniency rules the more cartelized the economy is. 相似文献
This article examines cost economies, productivity growth and cost efficiency of the Chinese banks using a unique panel dataset
that identifies banks’ four outputs and four input prices over the period of 1995–2001. By assessing the appropriateness of
model specification, and making use of alternative methodologies in evaluating the performance of banks, we find that the
joint-stock commercial banks outperform state-owned commercial banks in productivity growth and cost efficiency. Under the
variable cost assumption, Chinese banks display economies of scale, with state-owned commercial banks enjoying cost advantages
over the joint-stock commercial banks. Consequently, our results highlight the ownership advantage of these two types of banks
and generally support the ongoing banking reform and transformation that is currently taking place in China. 相似文献
Summary. This paper defines and studies optimality in a dynamic stochastic economy with finitely lived agents, and investigates the
optimality properties of an equilibrium with or without sequentially complete markets. Various Pareto optimality concepts
are considered, including interim and ex ante optimality. We show that, at an equilibrium with a productive asset (land) and sequentially complete markets, the intervention
of a government may be justified, but only to improve risk sharing between generations. If markets are incomplete, constrained
interim optimality is investigated in two-period lived OLG economies. We extend the optimality properties of an equilibrium with
land and give conditions under which introducing a pay-as-you-go system at an equilibrium would not lead to any Pareto improvement.
