Indian Business Process Outsourcing (BPO) exports industry has witnessed an exponential growth over the last few years. This has been accompanied by a shortage of talented skilled workers to serve the BPO sector. Attracting and retaining talented employees has become the chief challenge of HR departments in the BPO industry. This study examines the demographic antecedents of job abandonment among call centre employees in India using a large firm level data. The theoretical and practical implications of the findings are discussed. 相似文献

The causal link between tourism receipts and GDP has recently become a major focus in the tourism economics literature. Results obtained in recent studies about the causal link appear to be sensitive with respect to the countries analysed, sample period and methodology employed. Considering the sensitivity of the causal link, we use rolling window and time-varying coefficient estimation methods to analyse the parameter stability and Granger causality based on a vector error correction model (VECM). When applied to South Africa for the period 1960–2011, the findings are as follows: results from the full-sample VECM indicate that there is no Granger causality between tourism receipts and GDP, while the findings from the time-varying coefficients model based on the state-space representation show that tourism receipts have positive-predictive content for GDP for the entire period, with the exception of the period between 1985 and 1990. Full-sample time-varying causality tests show bidirectional strong causality between tourism receipts and GDP. 相似文献

This objective of this study is to examine the linkages between real (economic) and financial variables in the United States in a regime-switching environment that accounts explicitly for high volatility in the stock market and high stress in financial markets. Since the linearity test shows that the linear model should be rejected, we employ the Markov-switching VECM to examine the same objective using the Bayesian Markov-chain Monte Carlo method. The regime-dependent impulse response function (RDIRF) highlights the increasing importance of the financial sector of the economy during stress periods. The responses and their fluctuations are significantly greater in the high-volatility regime than in the low-volatility regime. 相似文献

We study fixed price temporary equilibria (with rationing) and sequences of temporary equilibria in a three commodities (goods, labor, bonds) overlapping generations model with endogenous investment. Young consumers, living two periods, work, consume, and buy bonds for financing next period's consumption. New firms, existing for two periods, make a production plan for the next period, taking into account expected rationing, assumed similar to present rationing. The plan determines the amount of goods to buy as capital, financed by bonds. Old firms produce, using labor and the previously bought capital. Different regimes exist and expectations can be self-fulfilling and self-destroying.We are grateful to the referees for helpful comments. 相似文献

Using the Vietnam Household Living Standards Survey 2008, we explore the differences in pro‐poor growth performance in provinces in Vietnam according to the quality of the provinces’ institutions that support private sector activity. We exploit the localized and varying effect of French colonial legacy across Vietnamese provinces to address the endogeneity of institutions. We find strong and robust evidence of a positive effect of good‐quality institutions that support private sector activity on pro‐poor growth and that enhanced working hours and hourly wage and extended income from non‐farm self‐employment play critical roles in this outcome. 相似文献

One of the key factors for a thriving cloud computing market is the ‘interoperability’ between the relevant hardware and software that govern the cloud services. While a complete interoperability means different cloud users being able to exchange the management tools, server images and other software, this is infrequently realised because users are locked into (proprietary) cloud ecosystems. This (problem of vendor lock-in) is potentially accompanied with another problem revolving around the content delivery networks being integrated with the distinct clouds along with possible harms to media pluralism as well as interoperability. In view of these concerns, this study focuses on competition law, standardisation and regulatory policies, and elaborates on to what extent cloud interoperability needs to be secured under EU legal fora. Overall, it is found that vendor lock-in might be attended by ‘coupling’ and complex ‘layering’ strategies, whereas efficiency and/or security based justifications would arise as the counter-balancing reasons. Based on the findings, the study concludes that while focusing on the vertical (i.e., vendor lock-in) concerns, a comprehensive viewpoint needs to be upheld, allowing efficiencies (i.e., proprietary enhancements) based on the architectural design and innovations, obviating narrowly-fashioned (i.e., foreclosure-based) interventions such as in Microsoft case. It is also underlined that cloud interoperability has a content dimension that would require a broader perspective, extending to horizontal concerns and requirements within the context of EU policy making strategies. 相似文献

Risk aversion theory is based on an individual's choice among risky assets with expected utility in its foundation. It is about investor behavior (i.e., investor choice), under normal circumstances, toward assets with various levels of risk. A positive and marginally diminishing relationship between risk and return exists. This study is about investor behavior related to their response (not choice) to risk. We present an argument and supporting evidence that investors’ return response to risk is increasing with the level of risk. Thus, investor behavior is subject to change and the level of risk is a determinant of such change. We also explain the negative time‐series correlation between risk and return. 相似文献

Recent studies have analysed the ability of measures of uncertainty to predict movements in macroeconomic and financial variables. The objective of this paper is to employ the recently proposed nonparametric causality-in-quantiles test to analyse the predictability of returns and volatility of sixteen U.S. dollar-based exchange rates (for both developed and developing countries) over the monthly period of 1999:01–2012:03, based on information provided by a news-based measure of relative uncertainty, i.e., the differential between domestic and U.S. uncertainties. The causality-in-quantile approach allows us to test for not only causality-in-mean (1st moment), but also causality that may exist in the tails of the joint distribution of the variables. In addition, we are also able to investigate causality-in-variance (volatility spillovers) when causality in the conditional-mean may not exist, yet higher order interdependencies might emerge. We motivate our analysis by employing tests for nonlinearity. These tests detect nonlinearity, as well as the existence of structural breaks in the exchange rate returns, and in its relationship with the EPU differential, implying that the Granger causality tests based on a linear framework is likely to suffer from misspecification. The results of our nonparametric causality-in-quantiles test indicate that for seven exchange rates EPU differentials have a causal impact on the variance of exchange rate returns but not on the returns themselves at all parts of the conditional distribution. We also find that EPU differentials have predictive ability for both exchange rate returns as well as the return variance over the entire conditional distribution for four exchange rates. 相似文献
