The US dollar- scenario of a world currency

The exchange rate of the US dollar fell sharply last year. What part was played by the adverse “fundamentals” of the US economy, the large current account deficit, the country’s heavy foreign indebtedness and the substantial budget deficit? How will the dollar behave in future?     

Workplace democracy in the lab

While intuition suggests that empowering workers to have some say in the control of the firm is likely to have beneficial effects, empirical evidence of such effects is hard to come by because of numerous confounding factors in the naturally occurring data. We report evidence from a real‐effort experiment confirming that worker performance is sensitive to the process used to select the compensation contract. Groups of workers that voted to determine their compensation scheme provided significantly more effort than groups that had no say in how they would be compensated. This effect is robust to controls for the compensation scheme implemented, worker characteristics such as ability and gender, and possible sorting.     

Mind the Intended‐Implemented Gap: Understanding Employees’ Perceptions of HRM

This study aims to shed light on the implementation of HR practices as a key piece of the human resource management (HRM)–performance puzzle. Although the literature suggests that discrepancies between the organization's intended and implemented HR practices are essential to understanding employees’ perceptions of and reactions to HRM, little attention has been devoted to this issue. Drawing upon a multiple‐case study of German health and social services organizations, we therefore explore the linkages (and potential gaps) between intended, implemented, and perceived HR practices. Our study provides new insights into the underlying mechanisms of this relationship, highlighting an organization's ability to leverage its resources as playing a crucial moderating role in implementing intended HR practices, while employees’ expectations of HRM moderate the link between implemented and perceived HR practices. We advance a set of propositions that contributes to a more nuanced, multilevel understanding of the complex phenomenon of HRM implementation. © 2014 Wiley Periodicals, Inc.     

NEA Presidential Address: Gender Inequality and Human Development in Sub- Saharan Africa

This Presidential Address considers the effects of gender inequality on human development in Sub-Saharan Africa. Parameter estimates from quantile and ordinal categorical latent variable specifications of the relationship between components of the Human Development Index and measures of gender inequality suggests that human development in Sub-Saharan Africa increases with respect to improvements in several measures of gender inequality. The results suggest that inegalitarian laws, norms, traditions and codes of conduct toward women constrain both human and economic development in Sub-Saharan Africa.     

Dynamics of Idiosyncratic Volatility and Market Volatility: An Emerging Market Perspective

Abstract

Estimating idiosyncratic volatility (IVOL) using various model-dependent and model-independent measures, we investigate the characteristics of aggregate IVOL in Malaysia over the period 1990–2008. The IVOL estimated in all models have similar patterns and has no trend over the sample period. There is evidence of episodic phenomenon. During financial crisis periods, market volatility is relatively higher than IVOL – a plausible reason is high correlation between firms' returns. Small firms and low-priced stocks appear to influence IVOL more than large firms and high-priced stocks. In Malaysia, market volatility and IVOL may predict GDP growth.     

Determinants of efficiency of vegetable production in smallholder farms: The case of Ethiopia

Improving production efficiency remains as a plausible means of increasing productivity when resource reallocation, and the creation and adoption of new technologies are limited. Technical, allocative and economic efficiencies are derived from a sample of smallholder vegetable farmers in Ethiopia using parametric and non-parametric methods. The results reveal that the two methods yield similar estimates and the existence of substantial inefficiencies in production as well as efficiency differentials among farmers. The analysis of the determinants of efficiency of vegetable production using regression models show that low asset ownership, illiteracy, large family size, inadequate extension contacts, small farm size, age, low off/non-farm income and high consumer spending are the major socio-economic factors causing inefficiency of vegetable production in the study areas. A comparison of the market-driven (vegetables) with the whole-farm (crops and livestock) production efficiency indicates that lower economic efficiency scores for the former might be related to the limited access to capital markets, high consumer spending, and large family size.
