Macro explanatory factors of Turkish tourism companies’ stock returns

This study examines whether the stock prices of Turkish tourism companies respond to growth in eight macro-economic variables namely, consumer price index, imports, exchange rate, consumer confidence index, oil price, money supply, foreign tourist arrivals, and monthly stock market return. By applying the Granger causality procedure, we find that growth in the consumer confidence index and imports could Granger cause tourism companies’ stock returns among eight macro factors in Turkey during the 2005 to 2013 period. After considering the structural break that occurred in 2007, the pre-break results indicate that the consumer confidence index, exchange rate, and foreign tourist arrivals could Granger cause tourism stock returns. However, the results in the post-structural break period reveal that only growths in oil prices and imports are significant.     

The effects of national culture on the role of participation in different task situations

Prior studies primarily in Anglo-American and Asian cultural settings have found that budgetary participation interacts with reliance on accounting performance measures and task situations to affect managerial attitudes. Researchers have questioned if such findings can also be found in different cultural environments. As France has a high power distance and high individualism culture which is different from those of both the Anglo-American and Asian nations, this study investigates if such cultural differences may affect the findings of prior studies. Based on a sample of 44 French managers, the results indicate a similar significant three-way interaction effect. However, they also indicate that French managers have low levels of budgetary participation. Participation also has an insignificant effect on managers' job satisfaction in high task difficulty situations. These results are contrary to those of prior studies in Anglo-American and Asian cultural settings and may have important implications for the study of cultural effects on management control systems.     

Social capital and career outcomes: a study of Chinese employees

This study examines the impacts of social capital on employees’ career outcomes in the Chinese context. Access to information and access to resources are hypothesized as the mediators in the relationships. A new measure of individual social capital is developed and used as the key predictor of the outcome variables. Data were collected from a survey administered to 184 employees in a state-owned enterprise. The results of regression analysis showed that individual social capital enhanced both career satisfaction and career achievement among Chinese employees. Further, access to information and access to resources were found to mediate the above relationships. The theoretical and practical implications are discussed.     

Exact aggregation under summability and homogeneity with individually variable prices

Exact aggregation of a system of individual expenditure functions with a single, individually variable price is analyzed. It is shown, under summability and homogeneity, that the individual and aggregate expenditure functions must take one of two specific functional forms.     

On Valuing Participating Life Insurance Contracts with Conditional Heteroscedasticity

In this paper, we consider a novel approach for the fair valuation of a participating life insurance policy when the dynamics of the reference portfolio underlying the policy are governed by an Asymmetric Power GARCH (APGARCH) model with innovations having a general parametric distribution. The APGARCH model provides a flexible way to incorporate the effect of conditional heteroscedasticity or time-varying conditional volatility and nests a number of important symmetric or asymmetric ARCH-type models in the literature. It also provides a flexible way to capture both the memory effect of the conditional volatility and the asymmetric effects of past positive and negative returns on the current conditional volatility, called the leverage effect. The key valuation tool here is the conditional Esscher transform of Bühlmann et al. (1996, 1998). The conditional Esscher transform provides a convenient and flexible way for the fair valuation under different specifications of the conditional heteroscedastic models. We illustrate the practical implementation of the model using the S&P 500 index as a proxy for the reference portfolio. We also conduct sensitivity analysis of the fair value of the policy with respect to the parameters in the APGARCH model to document the impacts of different conditional volatility models nested in the APGARCH model and the leverage effect on the fair value. The results of the analysis reveal that the memory effect of the conditional volatility has more significant impact on the fair value of the policy than the leverage effect.
