This paper examines the dynamics of income distribution and convergence in Latin America during the period 1960 to 2000. Our results, based on the intradistribution dynamics approach, reveal a “twin peaks” dynamics, which echoes findings reported for the OECD, the Asia Pacific Basin and worldwide. Notable differences, however, are found between the income dynamics in Latin America and in these other regions. Further, our findings indicate that physical capital investment and health capital serve to explain Latin America’s “twin peaks” polarization. Other factors, such as geographical proximity, trade openness and human capital, are also found to help explaining it to some extent. We gratefully acknowledge the helpful comments and suggestions of the referee.  相似文献

The evolving brand logic: a service-dominant logic perspective   总被引:1,自引:0,他引:1  
The meanings of brand and branding have been evolving over the past several decades. This evolution is converging on a new conceptual logic, which views brand in terms of collaborative, value co-creation activities of firms and all of their stakeholders and brand value in terms of the stakeholders’ collectively perceived value-in-use. The authors argue that this new logic parallels and reflects the related, evolving service-dominant (S-D) logic in marketing. They provide an historical account of the branding literature, organize it into eras, and connect it to the evolution in marketing as captured by S-D logic. The analysis provides further support for the S-D logic of marketing and suggests a related research agenda for furthering the understanding of brand and branding. It also suggests that marketing managers might benefit from investing resources in building strong brand relationships with all of their stakeholders and a service-dominant firm philosophy built around brand value co-creation.  相似文献

It has been observed that customer service workers often develop mutually supportive coping strategies to protect themselves from the emotional strain of overwork. These strategies can receive tacit support from supervisors, who may accept them as a means of getting the work done. The study explores the impact of a number of different forms of support on emotional exhaustion among a group of 480 call centre workers focusing, in particular, on the role of supportive behaviours relating to absence taking. The research shows that a supportive co-worker absence culture and team leader absence permissiveness can lessen the effects of job demands on emotional exhaustion and improve worker well-being. The implications of these findings are discussed.  相似文献

In hazard models, it is assumed that all heterogeneity is captured by a set of theoretically relevant covariates. In many applications however, there are ample reasons for unobserved heterogeneity due to omitted or unmeasured factors. If there is unmeasured frailty, the hazard will not only be a function of the covariates but also of the unmeasured frailty. This paper discusses the implications of unobserved heterogeneity on parameter estimates with application to the analysis of infant death on subsequent birth timing in Ghana and Kenya using DHS data. Using Lognormal Accelerated Failure Time models with and without frailty, we found that standard models that do not control for unobserved heterogeneity produced biased estimates by overstating the degree of positive dependence and underestimating the degree of negative dependence. The implications of the findings are discussed.  相似文献

This article examines the response of consumer and business confidence to five measures of change in Australian monetary policy. Actual, expected and surprise increases in the official cash rate target and related interest rates are shown to negatively impact consumer sentiment. Business confidence is less affected by increases in the cash rate target, but is negatively affected by an increase in the 90-day bank accepted bill rate. Tests for model stability and asymmetries in the response of sentiment to increases and decreases in interest rates otherwise find only limited evidence for monetary policy having a perverse signalling effect on sentiment.  相似文献

As has been seen in other contexts, workers in similar occupations earned much higher wages in Canada than Europe during the 1920s. This observation and related aspects of immigration are addressed with a life-cycle model of the migration decision. The characteristics of immigrants from five European countries: Ireland, Italy, the Netherlands, Poland, and Sweden, are explored in a way that sheds light not just on those population flows but on the process of immigration generally. We draw on passenger manifests from immigrant ships for information on the individual migrants. Simulations, based partly on the these manifests, reveal that the costs of migration, borrowing constraints, concern for status, and country-specific taste preferences account for key immigrant characteristics, and help explain the large wage differentials that persisted despite Canada’s relatively open immigration policy.  相似文献

Generic Bordeaux red wine (basic claret) can be regarded as being similar to an agricultural commodity. Production volumes are substantial, they are traded at high frequency and the quality of the product is relatively homogeneous. Unlike other commodities and the top-end wines (which represent only 3% of the traded volume), there is no futures market for generic Bordeaux wine. Reliable forecasts of prices can to large extent replace this information deficiency and improve the functioning of the market. We use state-space methods with monthly data to obtain a univariate forecasting model for the average price. The estimates highlight the stochastic trend and the seasonality present in the evolution of the price over the period 1999 to 2016. The model predicts the path of wine prices out of sample reasonably well, suggesting that this approach is useful for making reasonably accurate forecasts of future price movements.  相似文献

The purpose of this study is to examine the effects of State regulation that determines the extent of professional independence of advanced practice nurses (APNs). We find that in States where APNs have acquired a substantial amount of professional independence, the earnings of APNs are substantially lower, and those of physicians assistants (PAs) are substantially higher, than in other States. These results are striking since PAs are in direct competition with APNs; the only real operational difference between these groups is that PAs are salaried employees who must work under the supervision of a physician. The implication is that physicians have responded to an increase in professional independence of APNs by hiring fewer APNs and more PAs. The finding that earnings of APNs decline when they attain more professional autonomy vis-à-vis physicians reinforces work by Sass and Nichols on physical therapists.The content is the responsibility of the authors and does not represent official positions of the Federal Reserve Bank of St. Louis or the Federal Reserve SystemJEL classification: I11, I18, J31, J44, L51  相似文献

The incentive dilemma refers to a situation in which incentives are offered but do not work as intended. The authors suggest that, in an interorganizational context, whether a principal-provided incentive works is a function of how it is evaluated by an agent: for its contribution to the agent’s bottom line (instrumental evaluation) and for the extent it is strategically aligned with the agent’s direction (congruence evaluation). To further understand when incentives work, the influence of two key contextual variables—industry volatility and dependence—are examined. A field study featuring 57 semi-structured depth interviews and 386 responses from twin surveys in the information technology and brewing industries provide data for hypothesis testing. When and whether incentives work is demonstrated by certain conditions under which the agent’s evaluation of an incentive has positive or negative effects on its compliance and active representation. Further, some outcomes are reversed in the high volatility condition.  相似文献

The assessment of “patient value” is fundamental to clinical trials, real world evidence studies, and outcomes-based reimbursement schemes. Measures of health-related quality-of-life (HRQoL) are widely used in health research. Such measures are effective in determining the presence or absence of symptoms and functional ability. However, HRQoL measures were not intended, nor designed, to determine the value to patients of alternative health states. Functions have no intrinsic value—they are a means to fulfil human needs. However, needs can be met in a variety of ways, for example by adopting different functions or by the provision of social services. It is possible to analyze all functions in terms of the needs they satisfy. A needs model has been applied in health research since the 1990s. It is concerned with the extent to which human needs are fulfilled in the presence of disease and its treatment. It is argued that this is the major concern of the patient. Needs-based measures are patient-centric and produce a valid unidimensional index of outcome. Consequently, they provide a direct means of measuring patient value. This approach provides the possibility of evaluating health services in terms of the value they provide to consumers and payers. It also has a role to play in real-world evidence studies and outcomes-based reimbursement. It is recommended that greater attention is given in future to the development of patient-reported outcome measures that provide direct assessments of patient value.  相似文献
