Competition in Turkish mobile telecommunications markets: Price elasticities and network substitution

This paper estimates demand elasticities for Turkish mobile telecommunications markets. In contrast to most other studies, firm-level data is used to estimate dynamic panel data models including instrumental variable techniques. Both short- and long-run elasticities are calculated, yielding a long-run price elasticity of −0.72 for the post-paid market and of −0.33 for the pre-paid market. The short-run price elasticity is estimated to be −0.36 for the post-paid market and −0.20 for the pre-paid market. In addition, there is evidence of fixed-to-mobile traffic substitution for consumers who use pre-paid cards.     

On the Term Structure of Sovereign-Debt Contracts*

This paper studies the term structure of a repudiation-proof debt contract encompassing many sequentially scheduled short-term loans in a principal-agent (lender-sovereign borrower) framework. the extension of each loan is conditional on the full repayment of the previous loans in due maturity. Both direct sanctions and loss of access to the international credit market are present as debt-repudiation costs. It is shown that the proposed repudiation-proof composite contract exhibiting decreasing loan sizes and increasing maturities is better for coping with the enforcement problems that characterize sovereign lending.     

The impact of IQ and EQ on pre-eminent achievement in organizations: implications for the hiring decisions of HRM specialists

In this study, IQ and EQ determinants of pre-eminent achievement in organizations were explored to help HRM specialists in selecting more appropriate job applicants, having potential for outstanding performance in their career paths. Several EQ elements were proved the most important in the achievement. However, IQ elements still play a very important role in superior performance. Results also exhibit that correlation of IQ and EQ levels of superior performers is significant and strong. In conclusion, HRM specialists have to test both IQ and EQ in the hiring process, to create a high-performing workforce in their organizations.     

Interaction of organizational commitment and job satisfaction of nurses and medical secretaries in Turkey

The main aims of this study is to explain the relationship between job satisfaction and organizational commitment and to investigate the effects of gender, education level, age, monthly income, ownership type of the employed hospital, length of employment in the hospital, job and marital status on organizational commitment and job satisfaction. The research was carried out in three hospitals in Turkey. The research population includes 872 people: 677 nurses and 195 medical secretaries. All the questions on the research instruments were answered by 55.4% of the population. A significant and positive relationship was found between job satisfaction and organizational commitment.     

Attitudes Toward Ethically Questionable Negotiation Tactics: A Two-Country Study

Current research has identified five discrete US negotiation tactics, a traditional one considered to be ethical, and four considered to be ethically questionable. Scholars have independently used culture to explain how the endorsement of these five negotiation tactics varies across nations. They have also independently used interpersonal trust and ethics propensity to explain antecedents of the endorsement of those five negotiation tactics. This research combines all those variables into one model that investigates the influence of horizontal and vertical individualism–collectivism, ethical idealism, and trust propensity on employees’ attitudes toward ethically questionable negotiation tactics in Israel and Kyrgyzstan. A survey questionnaire was translated from English to Hebrew and Kyrgyz, and 615 responses were collected from employees in various industries in the two countries. We empirically confirmed three types of questionable negotiation tactics discovered in previous one-nation studies, namely, pretending, deceiving, and lying. Vertical individualism was found to be positively, and horizontal collectivism was found to be negatively, related to pretending, deceiving, and lying. Ethical idealism was found to be negatively related to the endorsement of the lying tactics, while trust propensity was negatively related to the pretending tactics. Compared with Israel, employees’ endorsement of ethically questionable negotiation tactics was significantly higher in Kyrgyzstan. Contribution to theory and practice is discussed.     

Momentum or market? Determinants of large stock price changes in an emerging market

The aim of this study is to investigate the determinants of large price changes in Turkey. We also provide additional evidence on determinants of large price changes in different macroeconomic environments, specifically on the pre-crisis and post-crisis periods. Using recurrent event analysis with stratified observations and frailty effects, our findings suggest that momentum has a significant impact on large price changes during both pre-crisis and post-crisis periods. However, the impact of market is more significant on the estimation of large price declines in the pre-crisis period and of large price increases in the post-crisis period. Additional findings suggest that liquidity and market-to-book ratio have positive, firm size has a negative impact on likelihood of large price changes regardless of the direction of the stock price change and macroeconomic environment. Findings of this study provide new insights into the understanding of large price changes in an emerging market.     

Transitioning into a ‘throwaway planet’

It is generally considered to be safer for the environment to repair a malfunctioning product for further reuse than to dispose of it and replace it with a newly manufactured product, unless the product is being replaced with a more energy efficient alternative. However, whereas United States has long been labelled a ‘throwaway society’, this paper presents the results of an international consumer survey which demonstrates that as other nations develop with respect to GDP per Capita (Gross Domestic Product per Capita), they too start transitioning into throwaway societies. This transition then calls into account of just how environmentally damaging this practice will become.     

HRM and performance—The role of talent management as a transmission mechanism in an emerging market context

This paper investigates the link between HRM practices, talent management (TM), and firm performance and examines the role of HRM/business strategy alignment in an emerging market context. Through survey evidence gathered from 198 respondent firms, this study shows that TM, when focused on a series of practices aimed at developing workforce networks and social capital, is a key transmission mechanism mediating the relationship between HRM and firm performance. HRM strategy and business strategy alignment increases these performance impacts but is not an essential component in the HRM‐TM‐performance link.
