Social comparisons in wage delegation: experimental evidence

We make two main contributions in this article. We examine whether social comparisons affects workers’ performance when a firm can choose workers’ wages or let them choose their own. Firms can delegate the wage decision to neither, one or both workers in the firm. We vary the information workers receive, finding that social comparisons concerning both wages and decision rights affect workers’ performance. Our second contribution is methodological. We find that our treatment effects are present with both stated effort and a real-effort task, which suggests that both approaches may yield similar results in labor experiments.     

Green Practices and Organizational Design as Sources of Strategic Flexibility and Performance

Green competences are dynamic capabilities based on practices (green practices), routines and structures that can be used to detect opportunities, make the most of them and use them to transform organizations. With this in mind, we explore the relationships between environmental management, organizational performance, and organizational processes and practices. We identify three key constructs related to green competences: (1) hybrid structures, (2) environmental best practices and (3) strategic flexibility, a key variable connecting structural design and green practices to organizational performance. We propose that the implementation of specific organizational structures characterized by the inclusion of market‐driven control practices within hierarchies (internal hybrids) could enhance firms' environmental responsiveness and deployment of green best practices. In addition, we suggest that green practices and structures are positively related to the development of strategic flexibility, driving above‐average returns in dynamic environments. To test these hypotheses, we use data from the European aviation industry. Copyright © 2015 John Wiley & Sons, Ltd and ERP Environment     

Dynamic effects of idiosyncratic volatility and liquidity on corporate bond spreads

We study the dynamic impact of idiosyncratic volatility and bond liquidity on corporate bond spreads over time and empirically disentangle both effects. Using an extensive data set, we find that both idiosyncratic volatility and liquidity are critical mainly for the distress portfolios, i.e., low-rated and short-term bonds; for others only volatility matters. The effects of volatility and liquidity shocks on bond spreads were both exacerbated during the recent financial crisis. Liquidity shocks are quickly absorbed into bonds prices; however, volatility shocks are more persistent and have a long-term effect. Our results overall suggest significant differences between how volatility and liquidity dynamically impact bond spreads.     

Beyond the Information Technology Agreement: Harmonisation of Standards and Trade in Electronics

Product standards can have a dual impact on costs and, thus, on trade. They can impose costs on exporters as it may be necessary to adapt products for specific markets (cost effect). In contrast, standards can reduce exporters’ information costs as they convey information on product characteristics (informational effect). Using a new World Bank database of European standards for electronic products, we examine the net impact of internationally harmonised European standards on European Union imports. We find that European Union standards for electronic products that are harmonised to international standards have a significant and a positive net effect on trade. The results suggest that efforts to promote trade in electronic products could be complemented by steps to promote standards harmonisation. This might include, for example, restarting talks to extend the WTO’s Information Technology Agreement to commitments to harmonise national standards in electronic products.     

Banking sector development and interest rate volatility in emerging economies

Over the last decades, macroeconomic stability is said to be one of the major concerns of emerging economies. Financial sector as a core of macroeconomic stability has been under close consideration of policy makers. The relationship between interest rate uncertainty and banking sector development as one of the most important indicators of financial sector development, especially for emerging economies, has not received enough attention in the literature. Perhaps this article is the most comprehensive study that investigates the relationship between interest rate uncertainty and banking sector development for a large group of emerging economies. To do this, the short-run and long-run models using a bounds testing approach to cointegration for 12 emerging economies over the period 1980–2011 have been developed. Estimated results from all models indicate that interest rate uncertainty has significant effect on banking sector development in both short-run and long-run phenomena in the majority of countries. The findings indicate that the link between interest rate uncertainty and banking sector development in each country depends on each country’s specific structure.     

The Voluntary Continuation in the Obligatory System of the Social Security Law

The system of obligatory insurance, regulated by the Social Security Law, includes the design of a mixed system, which allows workers to continue contributing to the social security. This mixed system, called voluntary continuation in the obligatory system, contemplates the option for workers who have concluded a work relationship and who wish to continue accumulating weekly contributions necessary to obtain the disability and life insurance rights, such as those of dismissal in old age, and are considered in the Social Security Act of 1973.     

Network externalities in consumer spending on lottery games: evidence from Spain

We use data from two nationally representative Spanish surveys in 2005 and 2006 to investigate spending on lottery games. Estimates from Tobit and double hurdle models of participation in lottery markets and spending on lottery tickets find that frequent participation in one game is not associated with an increased or decreased probability of participating in other games, but is associated with increased spending on other games. Consumer spending on different lottery games exhibits inter-related consumption decisions. Also, the assumptions underlying the double hurdle model, but not the Tobit model, better describe consumer spending on lottery tickets in Spain.     

Properties of the Sample Autocorrelations of Nonlinear Transformations in Long-Memory Stochastic Volatility Models

The autocorrelations of log-squared, squared, and absolute financialreturns are often used to infer the dynamic properties of theunderlying volatility. This article shows that, in the contextof long-memory stochastic volatility models, these autocorrelationsare smaller than the autocorrelations of the log volatilityand so is the rate of decay for squared and absolute returns.Furthermore, the corresponding sample autocorrelations couldhave severe negative biases, making the identification of conditionalheteroscedasticity and long memory a difficult task. Finally,we show that the power of some popular tests for homoscedasticityis larger when they are applied to absolute returns.     

Learning to Compete: Transforming Firms in the Face of Radical Environment Change

Over the last decade, Latin American economies and companies have witnessed substantial changes as their economies have been reformed and opened to world markets. Firms that have adapted to these changes may have useful lessons to offer to companies in other countries as they face economic transformation and expanding competition.
