The impact of abusive supervision and co-worker support on hospitality and tourism student employees’ turnover intentions in Ecuador

Ram (2015. Hostility or hospitality? A review on violence, bullying and sexual harassment in the tourism and hospitality industry. Current Issues in Tourism. doi:10.1080/13683500.2015.1064364) posits that violence and harassment are areas of concern within the hospitality industry, and scholarly interest in abusive supervision in the workplace has grown since the last decade. This study extends Ram's (2015. Hostility or hospitality? A review on violence, bullying and sexual harassment in the tourism and hospitality industry. Current Issues in Tourism. doi:10.1080/13683500.2015.1064364) assertion by examining the effect of abusive supervision experiences on student employees’ turnover intentions in a hospitality and tourism context in a high power distance culture, Ecuador. The results showed that abusive supervision was positively related to turnover intentions, and its effect was stronger than co-worker support, with the abusive supervision–turnover intentions relationship being fully mediated by perceived organizational support (POS). In addition, co-worker emotional support was found to attenuate the negative effects of abusive supervision on POS. All in all, the findings highlight the roles of POS in explaining the relation between abusive supervision and turnover intentions and co-worker emotional support in buffering the negative effect of abusive supervision. The important role of culture is discussed.     

MODELING THE EVOLUTION OF EXPECTATIONS AND UNCERTAINTY IN GENERAL EQUILIBRIUM

We develop methods to solve general equilibrium models in which forward‐looking agents are subject to waves of pessimism, optimism, and uncertainty that turn out to critically affect macroeconomic outcomes. Agents in the model are fully rational and conduct Bayesian learning, and they know that they do not know. Therefore, agents take into account that their beliefs will evolve according to what they will observe. This framework accommodates both gradual and abrupt changes in beliefs and allows for an analytical characterization of uncertainty. We use a prototypical Real Business Cycle model to illustrate the methods.     

A holonic framework to understand and apply information processes in evolutionary economics: survey and proposal

Economists unsatisfied with the basic neoclassical assumptions of rational economic actors and economic evolution towards equilibrium states founded the evolutionary economic approach. Their goal was to provide more realistic assumptions regarding economic agents and their institutional environments. The Modern Synthesis (MS), the current conceptual paradigm for biological evolution, was used as a source of inspiration for conceptual development. Along the biologically inspired line of thought, the Generalized Darwinism (GD) initiative relies on the abstraction of the MS to provide a unifying conceptual framework for evolutionary economics. Despite its merits, GD has been subject to criticism, particularly regarding its level of abstractness and lack of an explicit account of the social and cognitive processes that drive economic evolution. The goal of this article is to introduce and explore an alternative conceptual framework for evolutionary economics: the Holonic Framework (HF). Contrary to GD, the HF is not biologically inspired, but builds upon the body of literature on the value of digital information networks. We discuss the analytical strengths and limitations of the HF relative to GD in light of several aspects pertinent to evolutionary economics (e.g. self-organization, culture, cognition, cooperation). Finally, by referring to an operationalization of the HF using Eurostat data, we show its practical strengths in comparison to GD.     

The Relationship between Brand Attachment and Consumers' Emotional Well-Being

The purpose of the study was to examine the relationship between brand attachment and emotional well-being of consumers based on the need for personal image management and feelings of arrogant pride. A study of 107 consumers of the Calvin Klein brand was performed. Data were analyzed using the structural equations modeling technique. The results indicated a positive relationship between brand attachment and emotional well-being of consumers. A relationship was also identified between brand attachment, image management, and emotional well-being, and brand attachment and arrogant pride. No relationship was identified between arrogant pride and emotional well-being.     

Does the digital divide matter? The role of information and communication technology in cross-country level and growth estimates

The bulk of information and communication technology is made of weightless, implementable, and infinitely reproducible knowledge products (such as software and databases). These products are transferred by telephone lines, accessed through internet hosts, and processed through personal computers. In this work, the coefficient of the labour augmenting factor in the aggregate production function has been estimated using proxies of variables crucially affecting the diffusion of (non-rival and almost non-excludable) knowledge products. This specification provides interesting answers to some of the open issues in the existing growth literature. The most recent information, though available for a limited period, shows that telephone lines, personal computers, mobile phones, and internet hosts significantly affect levels and growth of income per worker across countries. The result is robust to changes in sample composition, econometric specification, and estimation approach.     

Life beyond the Washington Consensus: An Introduction to Pro-poor Macroeconomic Policies

Abstract

This paper develops a rationale for the recession-induced inflation hypothesis. Within a conflicting claims framework we present a model in which both price leaders and organized workers set their nominal prices on the basis of a desired profit rate and a real wage target respectively. We argue that an absolute cost advantage in concentrated industries (for instance in fixed costs) may provide oligopolistic leaders sufficient margin to raise prices and restore a desired level of profitability during a recession. The resultizng unstable income distribution will set off an inflationary spiral if the firm's advantage in selling its output imparts an upward bias to the flexibility of input prices (specifically wages). Taking into consideration different scenarios for workers' bargaining power we present a simple simulation experiment to analyze the inflation and real wage paths of the economy after a negative output shock. When we endogenize output, we show that for a high degree of the bargaining power, output is likely to converge to a higher steady-state value.     

Financial market models with Lévy processes and time-varying volatility

Asset management and pricing models require the proper modeling of the return distribution of financial assets. While the return distribution used in the traditional theories of asset pricing and portfolio selection is the normal distribution, numerous studies that have investigated the empirical behavior of asset returns in financial markets throughout the world reject the hypothesis that asset return distributions are normally distribution. Alternative models for describing return distributions have been proposed since the 1960s, with the strongest empirical and theoretical support being provided for the family of stable distributions (with the normal distribution being a special case of this distribution). Since the turn of the century, specific forms of the stable distribution have been proposed and tested that better fit the observed behavior of historical return distributions. More specifically, subclasses of the tempered stable distribution have been proposed. In this paper, we propose one such subclass of the tempered stable distribution which we refer to as the “KR distribution”. We empirically test this distribution as well as two other recently proposed subclasses of the tempered stable distribution: the Carr–Geman–Madan–Yor (CGMY) distribution and the modified tempered stable (MTS) distribution. The advantage of the KR distribution over the other two distributions is that it has more flexible tail parameters. For these three subclasses of the tempered stable distribution, which are infinitely divisible and have exponential moments for some neighborhood of zero, we generate the exponential Lévy market models induced from them. We then construct a new GARCH model with the infinitely divisible distributed innovation and three subclasses of that GARCH model that incorporates three observed properties of asset returns: volatility clustering, fat tails, and skewness. We formulate the algorithm to find the risk-neutral return processes for those GARCH models using the “change of measure” for the tempered stable distributions. To compare the performance of those exponential Lévy models and the GARCH models, we report the results of the parameters estimated for the S&P 500 index and investigate the out-of-sample forecasting performance for those GARCH models for the S&P 500 option prices.     

Variances in staff-related management practices at eight European country subsidiaries of a global firm

The purpose of this study was to explore possible variances and commonalities in staff-related management practices at different country subsidiaries of the same multinational corporation (MNC). The study was exploratory, using data from ninety-six semi-structured interviews about current practices of management within eight European country subsidiaries. Results were based on 12,000 statements about management practices from staff in different countries. Analysis of the statements evidenced variances and commonalities in management practices in the country subsidiaries studied. It is suggested that variances are attributable to cultural factors, institutional pressures and other societal forces, and that commonalities might be explained by a common organizational culture. A theoretical model has been adapted to explain the conditions under which management practices take place in different country settings.
