A bstract . Latin Americans , principally Cubans , have entered Miami in large numbers since 1950. Although most who arrive have both urban and middle class backgrounds, which greatly facilitate their economic assimilation within the city, they have come in such large numbers that they are not becoming residentially assimilated with the non-Latin population. Instead, through invasion and succession they are creating their own ethnic ghettoes , a fact which is proven in this study through use of the location quotient and indexes of dissimilarity. Miami's Black population has always been isolated from both the Latin and non-Latin White populations. The city's major ethnic and family-cycle groups, however, have steadily become more isolated from the Latins since 1950. Furthermore, following the departure of these groups from neighborhoods invaded by Latins, they have relocated throughout the city in a way so that they are becoming increasingly more isolated from each other.  相似文献

Substantial revisions to the historical GDP data have led to both the outturn for 2012 being upgraded and to us revising up our estimation for 2013 growth from 1.4% to 1.9%. We have also nudged up our forecast for 2014 from 2.2% to 2.6%, which is partly influenced by the data revisions but also by business survey data which suggest that the recovery is finally broadening out towards business investment and exports…  相似文献

Numerous factors influence the development of the private healthcare sector. Therefore, the selection of these factors, which represent a potential opportunity for forming new entities, is a crucial from the point of view of entrepreneurship. In our research we selected strategic variables which have got direct influence on entrepreneurship in the private healthcare sector in Poland. Theoretical approach was based on literature review which have revealed the main factors and their relationships with entrepreneurship according to the previous research studies. This research study was conducted for the entire population of municipalities in Poland. Methodology was based on Intelligent Data Analysis (IDA) which can be applied for a large amounts of data in order to extract useful knowledge from it. Moreover, in research study were applied explanation techniques – decision rules –in order to indicate, to what extent the environment have influence on strategic choices conditioning the success of businesses. The results have revealed that it is possible to determine a set of the most important factors influencing entrepreneurship in the private healthcare sector in Poland. On the other hand, were indicated these variables which do not participate in process of influencing on entrepreneurship in private healthcare sector in Poland.

进入21世纪以来,国际竞争日益激烈。企业间的竞争已从技术、规模的竞争转向核心竞争力的竞争。对我国而言,建立在我国优秀传统文化基础之上的企业管理理念才是我们核心竞争力所在。目前我国在借鉴西方发达国家尤其是美国理论基础上建立的企业管理理论确实促进了我国企业的发展。但其文化与我国有巨大的差异,不能很好地服务于我国企业核心竞争力的塑造,其理论用于指导我们的实践时就出现了许多与我们实际不符的情况。而与我们有近似文化渊源的日韩在企业管理的实践中取得了令人瞩目的成就,相对于欧美而言,其做法对我们有更大的借鉴意义。  相似文献

Brodie and de Kluyver have reported empirical results in which simple naive models have produced forecasts as accurate as those derived from econometric models. I apply some recent theoretical results to show that these findings are plausible. I also suggest some general conditions under which econometric models will outperform naive models.  相似文献

Non-parametric estimation of the survival function using observed failure time data depends on the underlying data generating mechanism, including the ways in which the data may be censored and/or truncated. For data arising from a single source or collected from a single cohort, a wide range of estimators have been proposed and compared in the literature. Often, however, it may be possible, and indeed advantageous, to combine and then analyse survival data that have been collected under different study designs. We review non-parametric survival analysis for data obtained by combining the most common types of cohort. We have two main goals: (i) to clarify the differences in the model assumptions and (ii) to provide a single lens through which some of the proposed estimators may be viewed. Our discussion is relevant to the meta-analysis of survival data obtained from different types of study, and to the modern era of electronic health records.  相似文献

新《公司法》及司法解释有关股东代位诉讼的规定增加了股东诉讼的类型、明确了诉讼原告的范围、扩大了股东诉权的范围、加大了责任追究的力度,对股东诉权的保护取得了重大突破。但是,现行规定仍有粗疏之处,亟待新的司法解释出台,应从公司内部救济程序例外情形的具体化、地域管辖上的专属化、公司当事人地位的独立化、审理程序上的特殊化、限制原告实体性处分行为的程序化以及诉讼费用的非财产化等多个方面予以补充规定。  相似文献

We present a model in which workers with greater ability and greater risk tolerance move into performance pay jobs to capture rents and contrast it with the classic agency model. Estimates from the German Socio-Economic Panel confirm testable implications drawn from our model. First, before controlling for earnings, workers in performance pay jobs have higher job satisfaction, a proxy for on-the-job utility. Second, after controlling for earnings, workers in jobs with performance pay have the same job satisfaction as those not in such jobs. Third, those workers in performance pay jobs who have greater risk tolerance routinely report greater job satisfaction. While these findings support models in which workers capture rent, they would not be suggested by the classic agency model.  相似文献

Studies concerning total factor productivity (TFP) have investigated the effect of TFP on economic growth from a country-level perspective, which is a critical issue in the macroeconomics field. Few studies have examined how corporate financial decisions influence TFP from a firm-level perspective. Specifically, no extant studies have investigated how cash holdings affect firm productivity. This study utilizes data for firms in 65 countries during 1993–2017 to investigate the effect of cash holdings on TFP from a corporate perspective. The findings show that firms with higher cash holdings can enhance TFP. The results hold after considering endogenous problems, financial constraints, financial crises, corporate governance, institutional quality, and financial development as well as various robustness tests. Furthermore, we examine whether firms consistently invest their cash holdings into research and development (R&D) expenditures enhances firm productivity. The evidence indicates that higher cash holdings lead to steady increases in R&D expenditure, which improves firms’ TFP.  相似文献

Collateralized Social Relations: The Social in Economic Calculation   总被引:3,自引:0,他引:3  
Traditionally, economists have viewed social relations as "friction" or "impediments" to exchange and have excluded social relations from their analyses by assuming autonomous actors. Recently, however, a number of scholars—economists, sociologists, anthropologists, and other social scientists—have begun to discuss the numerous ways in which social arrangements both prompt and channel economic activity. Rational choice theory, social capital and network analysis, and agency and game theory, are among those approaches that consider the effects of social relations on economic action. In this paper we extend that discussion by arguing that social relations can function as "collateral" or assurance that an economic transaction will proceed as agreed by the parties involved. We review recent microeconomic theories and conjecture how they might be developed following this observation, which is derived from sociological and anthropological studies of economic action and organization.  相似文献

During the past decade a number of authors have proposed an extension to the basic Bradley-Terry model for estimation from the results of paired comparison experiments.
The extension was either meant to accommodate ties in the individual comparisons or to estimate the effect of the order of presentation of the objects in these comparisons and, if necessary, to correct for the bias which may result from this effect. All the extensions have in common that, in order to achieve the objective, one or more parameters are added to the basic model. In this paper a class of extensions is presented of which the ones already published may be considered special cases. Some of the extensions from this class are compared and evaluated using a numerical example.  相似文献

For the last half century, trade theorists, development economists, and development practitioners have been calculating what was claimed to be the shadow price of scarce foreign exchange. In fact, what they have been calculating is the social value of the receipt of a unit of a numeraire good from abroad, typically obtained from real models. In our paper, we explicitly deal with a model of a monetized economy, and we develop formulas for the social value of a unit of foreign currency, which, in general, differ from the traditional formulas.  相似文献

Abstract Seventeen intact collegiate groups of managers from eight companies and two publicly owned organizations described the organizational climates in which they worked. Their perceptions ranged from highly favourable to highly unfavourable. Did the occupational histories of the 134 managers influence their perceptions? Could the differences in their evaluations have arisen from other features of the environment, for which unobtrusive measures were available? Or was the level of each group in the hierarchy the prime determinant? All of these explanations have some plausibility in relation to the data presented. It is probably impossible to create‘the right climate’for management development by piecemeal strategies which ignore the significance of market success and deal only with the immediate experience of managers. On the other hand, a global strategy which concentrates on external factors and minimizes the importance of the individual's contribution in his particular location is likely to be equally defective. The major moderating variable in this study between the perceived developmental climate of the organization and the manager's occupational history was the salary he was paid.  相似文献
