This article first analyses the internal economic trajectory of the Cuban economic reforms and evaluates their effectiveness in delivering the extensive and intensive development needed to correct Cuba's structural and economic imbalances. It concludes that without the lifting of the US economic sanctions success will at best be only partial, with serious implications for long‐term stability. The article then evaluates the reasons for the US economic sanctions against Cuba and argues that while the embargo policy might have failed to topple the Cuban communist regime, it has served other, largely unacknowledged, purposes that are important in explaining why the policy has persisted. The article concludes by suggesting that the US is not likely to jettison the sanctions regime while Cuba's single‐party, state‐led economic system remains. At the same time, Cuba is not likely to jettison its single‐party system while the sanctions remain.  相似文献

In this paper we develop a test of infinite order degree stochastic dominance based on the use of the empirical Laplace transform function. Two applications are considered. One uses the income data of Anderson (Econometrica 64:1183–1193, 1996) and derives results consistent with his. In the other application we examine the dominance between the U.S. and U.K. stock markets. Using data on the S&P 500 and the FTALL-Share we show that the U.S. displays infinite order degree stochastic dominance of the U.K.

This paper reviews the literature on the association between lean production and performance. From this, propositions on the integration and evolution of operation and human resource management practices associated with the lean production concept are developed. Using 24 years of data on the use of seven core OM and HRM practices in British manufacturing firms, the potential link between integration in the use of practices and productivity is tested. In each year, three latent clusters are identified via ordered restricted latent class models; the cluster that consistently makes a more integrated use of practices outperforms the others. Furthermore, the longitudinal nature of the data permits modeling the growth curves of each practice in the sample, recognizing any similarity in growth and investigating whether or not an early integration in adoption of practices is associated with higher final productivity. The results show that pioneers are more productive, thus suggesting that the head start in integrating core OM and HRM practices associated with the lean production concept has paid off.  相似文献

abstract    Our study contributes towards a burgeoning literature that argues organizational performance is heavily influenced by what happens in the middle of the organization, rather than at the top. Examining the UK National Health Service, our study develops the work of Floyd and Wooldridge (1992 , 1994 , 1997 , 2000 ). It utilizes role theory to conceptualize changing experiences of middle managers in organizations as a role transition. Associated with this are problems of role conflict and role ambiguity ( Biddle, 1979 , 1986 ; Biddle and Thomas, 1966 ; Kahn et al., 1964 , 1966 ). Our study illustrates that there are limiting factors to a more strategic role for middle managers associated with the professional bureaucracy context. However, role conflict and ambiguity can be mediated by a socialization process, which values incoming identity and personal characteristics ( Van Maanen and Schein, 1979 ).  相似文献

Statistical Decision Problems and Bayesian Nonparametric Methods   总被引:1,自引:0,他引:1  
This paper considers parametric statistical decision problems conducted within a Bayesian nonparametric context. Our work was motivated by the realisation that typical parametric model selection procedures are essentially incoherent. We argue that one solution to this problem is to use a flexible enough model in the first place, a model that will not be checked no matter what data arrive. Ideally, one would use a nonparametric model to describe all the uncertainty about the density function generating the data. However, parametric models are the preferred choice for many statisticians, despite the incoherence involved in model checking, incoherence that is quite often ignored for pragmatic reasons. In this paper we show how coherent parametric inference can be carried out via decision theory and Bayesian nonparametrics. None of the ingredients discussed here are new, but our main point only becomes evident when one sees all priors—even parametric ones—as measures on sets of densities as opposed to measures on finite-dimensional parameter spaces.  相似文献

We measure the other-regarding behavior in samples from three related populations in the upper Midwest of the United States: college students, non-student adults from the community surrounding the college, and adult trainee truckers in a residential training program. The use of typical experimental economics recruitment procedures made the first two groups substantially self-selected. Because the context reduced the opportunity cost of participating dramatically, 91 % of the adult trainees solicited participated, leaving little scope for self-selection in this sample. We find no differences in the elicited other-regarding preferences between the self-selected adults and the adult trainees, suggesting that selection is unlikely to bias inferences about the prevalence of other-regarding preferences among non-student adult subjects. Our data also reject the more specific hypothesis that approval-seeking subjects are the ones most likely to select into experiments. Finally, we observe a large difference between self-selected college students and self-selected adults: the students appear considerably less pro-social.  相似文献

Employer-financed health insurance systems like those used in the United States distort firms’ labor demand and adversely affect the economy. Since such costs vary with employment rather than hours worked, firms have an incentive to increase output by increasing worker hours rather than employment. Given that the returns to employment exceed the returns to hours worked, this results in lower levels of employment and output. In this paper, we construct a heterogeneous agent general equilibrium model where individuals differ with respect to their productivity and employment opportunities. Calibrating the model to the U.S. economy, we generate steady state results for several alternative models for financing health insurance: one in which health insurance is financed primarily through employer contributions that vary with employment, a second where insurance is funded through a non-distortionary, lump-sum tax, and a third where insurance is funded by a payroll tax. We measure the effects of each of the alternatives on output, employment, hours worked, and wages.  相似文献

This article develops a new method of estimating inefficiencies in joint production and shows that unlike the approaches utilized in the previous studies of inefficiency, this method maintains a consistent relationship between the error term of a profit function and the error terms of its price derivatives. A useful by-product of the method is a proof of a Hotelling-like lemma that relates stochastic input demand and output supply functions to stochastic profit functions. While the previous studies fit a single frontier to data on all firms, this paper estimates a frontier unique to every observed firm to allow each one to have a different potential of achieving maximal levels of profit. The new method is applied in the analysis of annual data, 1984–1989, for U.S. commercial banks. Both the analytical and numerical results of the paper show that the residual that the previous studies attribute to inefficiency includes the effects of excluded variables and of inaccuracies in the specified functional forms. Once accurate estimates of these effects are subtracted from the residual, the distortions in the measured inefficiencies should be considerably reduced. Consequently, this article considers how such estimates might be obtained.  相似文献

The objectives of this article are to illustrate theoretically and empirically how to incorporate an ad valorem tariff in spatial equilibrium models and show the equivalence of three approaches (primal, dual and MCP) of spatial equilibrium trade modelling. The article lays out in detail the theory, empirical applications and the results for all three approaches so that trade modellers can easily follow and apply them in their work. The primal approach is commonly used by spatial equilibrium modellers, though the dual approach corresponds to the textbook depiction of consumer surplus, producer surplus and gains from trade. The Mixed Complementarity Problem (MCP) is not commonly used by spatial equilibrium modellers, though it is relatively simpler if the modeller knows the equilibrium conditions. This article also presents advantages and disadvantages of each approach.  相似文献

The long-run purchasing power parity (PPP) hypothesis is tested for nine bilateral sterling exchange rates, using recently developed techniques on cointegration and seasonal integration. The empirical findings show that none of the exchange rates and relative prices contain seasonal unit roots, but all have an autoregressive unit root. The cointegration tests overwhelmingly reject the PPP hypothesis as a long-run equilibrium condition for all countries concerned.  相似文献
