The shifting dependence dynamics between the G7 stock markets

The growing interdependence between financial markets has attracted special attention from academic researchers and finance practitioners for the purpose of optimal portfolio design and contagion analysis. This article develops a tractable regime-switching version of the copula functions to model the intermarkets linkages during turmoil and normal periods, while taking into account structural changes. More precisely, Markov regime-switching C-vine and D-vine decompositions of the Student’s t copula are proposed and applied to returns on diversified portfolios of stocks, represented by the G7 stock market indices. The empirical results show evidence of regime shifts in the dependence structure with high contagion risk during crisis periods. Moreover, both the C- and D-vines highly outperform the multivariate Student’s t copula, which suggests that the shock transmission path is as important as the dependence itself, and is better detected with a vine copula decomposition.     

Measuring the effects of monetary policy in Pakistan: a factor-augmented vector autoregressive approach

This paper examines the effects of monetary policy on macroeconomic variables in Pakistan’s economy using a data-rich environment. We used the factor-augmented vector autoregressive (FAVAR) methodology, which contains 115 monthly variables for the period 1992:01 to 2010:12. We compared the results of VAR and FAVAR model and the results showed that FAVAR model explains the effects of monetary policy which are consistent with the theory and better than the VAR model. VAR model shows the existence of price puzzle and liquidity puzzle in Pakistan while FAVAR model did not provide any evidence of puzzles. Interest rate negatively influences prices, hence interest rate is a good instrument for controlling inflation in Pakistan but it takes a lag of 5 months. The transmission of monetary policy shock is faster in case of prices as compared to output in Pakistan. FAVAR model supports the effectiveness of interest rate channel in Pakistan.     

Business Students' Perception of Ethics and Moral Judgment: A Cross-Cultural Study

Business relations rely on shared perceptions of what is acceptable/expected norms of behavior. Immense expansion in transnational business made rudimentary consensus on acceptable business practices across cultural boundaries particularly important. Nonetheless, as more and more nations with different cultural and historical experiences interact in the global economy, the potential for misunderstandings based on different expectations is magnified. Such misunderstandings emerge in a growing literature on "improper" business practices – articulated from a narrow cultural perspective. This paper reports an ongoing research on the cultural and contextual aspects of business ethics. The objective is to investigate how the perception/attitudes of business students towards the ethical dimension of doing business varies in different countries; Whether there are socio-cultural factors that influence the perception of ethicality in business practices. Research findings among business students in six countries: China, Egypt, Finland, Korea, Russia, and the U.S.A. are reported. While all groups had basic agreement on what constitutes ethical business practices, differences are found in the respondents' tolerance to damage resulting from "unethical" behavior. Without underestimating the role of national culture, variations in research results also point to the importance of current socio-political developments in the relevant countries. Implications for business teaching and management development are discussed.     

Shrinkage estimation for the mean of the inverse Gaussian population

We consider improved estimation strategies for a two-parameter inverse Gaussian distribution and use a shrinkage technique for the estimation of the mean parameter. In this context, two new shrinkage estimators are suggested and demonstrated to dominate the classical estimator under the quadratic risk with realistic conditions. Furthermore, based on our shrinkage strategy, a new estimator is proposed for the common mean of several inverse Gaussian distributions, which uniformly dominates the Graybill–Deal type unbiased estimator. The performance of the suggested estimators is examined by using simulated data and our shrinkage strategies are shown to work well. The estimation methods and results are illustrated by two empirical examples.     

Computer users’ ergonomics and quality of life – evidence from a developing country

This study is aimed at investigating the quality of workplace ergonomics at various Pakistani organizations and quality of life of computer users working in these organizations. Two hundred and thirty-five computer users (only those employees who have to do most of their job tasks on computer or laptop, and at their office) responded by filling the questionnaire covering questions on workplace ergonomics and quality of life. Findings of the study revealed the ergonomics at those organizations was poor and unfavourable. The quality of life (both physical and mental health of the employees) of respondents was poor for employees who had unfavourable ergonomic environment. The findings thus highlight an important issue prevalent at Pakistani work settings.     

Vertical price transmission in the Egyptian tomato sector after the Arab Spring

This study assesses price transmission along the Egyptian tomato food marketing chain in the period that followed the Arab Spring, which accentuated economic precariousness in Egypt. Static and time-varying copula methods are used for this purpose. Results suggest a positive link between producer, wholesaler and retailer tomato prices. Such positive dependence is characterized by asymmetries during extreme market events that lead price increases to be transferred more completely along the supply chain than price declines.     

It is not about what you read,but how you read it: the effects of sequencing rational and emotional messages on corporate and product brand attitudes

The study aims to examine the effects of message sequencing on attitudinal responses, namely on the effects of rational to emotional and emotional to rational message sequences on consumer attitudes toward the corporate and product brand. A between-subjects experiment was conducted using a stratified random sample. Participants were exposed to advertisements that communicate marketing messages either in a rational to emotional sequence or in an emotional to rational sequence for a product advertised by an organization. All attitudinal responses to the corporate and product brand were collected through a questionnaire that was given at the end of the experiment. The findings suggest advertisements that communicate marketing messages in an emotional to rational sequence produced more favorable attitudes toward the product brand among consumers as compared to advertisements that communicate in a rational to emotional sequence. However, no significant differences were found on consumer attitudes toward the corporate brand. These results remain true regardless of gender.     

How Perceived Corporate Social Responsibility Affects Employee Cynicism: The Mediating Role of Organizational Trust

This study examines to what extent perceived corporate social responsibility (CSR) reduces employee cynicism, and whether trust plays a mediating role in the relationship between CSR and employee cynicism. Three distinct contributions beyond the existing literature are offered. First, the relationship between perceived CSR and employee cynicism is explored in greater detail than has previously been the case. Second, trust in the company leaders is positioned as a mediator of the relationship between CSR and employee cynicism. Third, we disaggregate the measure of CSR and explore the links between this and with employee cynicism. Our findings illustrate that the four distinct dimensions of CSR of Carroll (economic, legal, ethical, and discretionary) are indirectly linked to employee cynicism via organizational trust. In general terms, our findings will help company leaders to understand employees’ counterproductive reactions to an organization, the importance of CSR for internal stakeholders, and the need to engage in trust recovery.     

CEO marital status and corporate cash holdings

We examine the effect of CEO marital status on corporate cash holdings. Consistent with the classical agency framework, we find that firms with single CEOs hold more cash compared to otherwise similar firms with married CEOs and that the excess cash held by single CEOs is significantly discounted by shareholders. Our findings survive a battery of tests to ease endogeneity and selection bias, confirming that results are not simply reflecting innate heterogeneity in preferences. Overall, our findings indicate that a variable outside the common firm- and macro-level determinants, CEO marital status, can significantly influence corporate policies.
