The role of direct flights in trade costs

Effects of direct flights on trade costs are investigated using micro price data at the city level. After controlling for local retail/distribution costs, traded input prices are obtained to be further used in the measurement of trade costs across cities through arbitrage conditions. The existence of a direct flight enters trade costs regressions negatively and significantly. The results are shown to be robust to the consideration of many control variables, nonlinearities in the effects of distance on trade costs, possible endogeneity of having direct flights between cities and alternative definitions of the data. The direct flights that are shown to be determined by bilateral air services agreements are further shown to reduce trade costs through an endogeneity analysis; the main policy implications are twofold: (i) international trade policies through aviation services, such as Open Skies Agreements of the US, are alternative trade policy tools to reduce international trade barriers; (ii) direct flights facilitate the integration of internal markets as in the case of European Union.     

Capital mobility and foreign debt sustainabilty: some evidence from Turkey

This paper address the extent of capital mobility and foreign debt sustainability in Turkey over the 1962–2003 period by examining the relationship between saving and investment, and imports and exports, respectively. The empirical investment is based on cointegration, error correction models, and threshold and momentum threshold autoregressive models. Our findings are consistent with the existence of capital mobility and the ‘Strong’ form of foreign debt sustainability.     

Traveler satisfaction in rapid rail systems: The case of Istanbul metro

Multifaceted characteristics of urban travel have an impact on the passengers' overall satisfaction with the transport system. In this study, we investigate the interrelationships among traveler satisfaction, travel and traveler characteristics, and service performance in a multimodal network that comprises of a trunk line and its feeder lines. We analyze the factors influencing the choices of access to rail transit stations and the satisfaction of transit travelers with the rapid rail transit systems. We quantitatively study these relationships and demonstrate the complexity of evaluating transit service performance. Since the interrelationships among variables affecting this system are mainly stochastic, we analyze the satisfaction with transit system problem using a Bayesian Belief Network (BBN), which helps capture the causality among variables with inherent uncertainty. Using the case of Istanbul, we employ the BBN as a decision support tool for policy-makers to analyze the rapid rail transit services and determine policies for improving the quality and the level of service to increase the satisfaction with transit system. In the case study, satisfaction with accessibility and access mode variables are found to be more effective variables than total travel time for travel time satisfaction, confirming the significant role of access in multimodal travels.     

A new perspective on the competitiveness of nations

The capability of firms to survive and to have a competitive advantage in global markets depends on, amongst other things, the efficiency of public institutions, the excellence of educational, health and communications infrastructures, as well as on the political and economic stability of their home country. The measurement of competitiveness and strategy development is thus an important issue for policy-makers. Despite many attempts to provide objectivity in the development of measures of national competitiveness, there are inherently subjective judgments that involve, for example, how data sets are aggregated and importance weights are applied. Generally, either equal weighting is assumed in calculating a final index, or subjective weights are specified. The same problem also occurs in the subjective assignment of countries to different clusters. Developed as such, the value of these type indices may be questioned by users. The aim of this paper is to explore methodological transparency as a viable solution to problems created by existing aggregated indices. For this purpose, a methodology composed of three steps is proposed. To start, a hierarchical clustering analysis is used to assign countries to appropriate clusters. In current methods, country clustering is generally based on GDP. However, we suggest that GDP alone is insufficient for purposes of country clustering. In the proposed methodology, 178 criteria are used for this purpose. Next, relationships between the criteria and classification of the countries are determined using artificial neural networks (ANNs). ANN provides an objective method for determining the attribute/criteria weights, which are, for the most part, subjectively specified in existing methods. Finally, in our third step, the countries of interest are ranked based on weights generated in the previous step. Beyond the ranking of countries, the proposed methodology can also be used to identify those attributes that a given country should focus on in order to improve its position relative to other countries, i.e., to transition from its current cluster to the next higher one.     

An exploratory analysis of the influence of human resource management activities and organizational climate on job satisfaction in Turkish banks

This study aims to explore the influence of human resource management (HRM) activities and organizational climate on job satisfaction in Turkish banks. The study first examines the relative influence of eight HRM activities of: (i) behavior and attitudes (in recruitment and selection); (ii) teamwork; (iii) extensive training; (iv) written policies; (v) training in multiple functions; (vi) incentives; (vii) performance appraisal; and (viii) feedback on performance on job satisfaction. Second, the influence of six factors relating to organizational climate are examined, again from the view point of their influence on job satisfaction. The second group factors are: (i) support for innovation; (ii) managerial competence and consistency; (iii) workload pressure; (iv) cohesion; (v) organizational boundaries; and (vi) organizational ethics. The data collected through interviews from 346 employees from 19 banks show that in addition to the positive impact of HRM activities, organizational climate in particular makes a significant contribution to job satisfaction. The paper presents the influence of the two groups of factors on job satisfaction and the mechanisms through which these factors foster job satisfaction and their implications for practitioners.     

Distribution of phosphorus resources between rich and poor countries: The effect of recycling

Phosphorus (P) is an essential input into agriculture with no substitute. Thus international and intertemporal P allocations greatly impact food security which requires increased food production for a growing world population. As high quality phosphorus mines are being depleted, recycling gains importance and developed countries explore new technologies for P recycling. We analyse the effects of P recycling in developed countries on global extraction of rock phosphates and the imports of developing countries. We build a resource extraction model for a competitive fertilizer market that reflects the fact that most developed countries have P-saturated soils while soils in many developing countries are P-deficient. Our model extends a simple cake eating problem. We consider two types of countries that differ in demand and recycling options. We find that P recycling in developed countries does not only prolong the resource life-time, but it also increases the developing counties' share of the resource.     

An Empirical Investigation of the Ethical Perceptions of Future Managers with a Special Emphasis on Gender – Turkish Case

This study presents an empirical investigation of the ethical perceptions of the future managers – Turkish university students majoring in the Business Administration and Industrial Engineering departments of selected public and private Turkish universities – with a special emphasis on gender. The perceptions of the university students pertaining to the business world, the behaviors of employees, and the factors leading to unethical behavior are analyzed. The statistically significant differences reveal that female students have more ethical perceptions about the Turkish business climate, behavior of employees, and the ethicalness of the behavior of the employees in comparison with their male counterparts.

The Effects of Corporate Ethical Values and Personal Moral Philosophies on Ethical Intentions in Selling Situations: Evidence from Turkish, Thai, and American Businesspeople

The goals of this study are to test a pattern of ethical decision making that predicts ethical intentions of individuals within corporations based primarily on the ethical values embedded in corporate culture, and to see whether that model is generally stable across countries. The survey instrument used scales to measure the effects of corporate ethical values, idealism, and relativism on ethical intentions of Turkish, Thai, and American businesspeople. The samples include practitioner members of the American Marketing Association in the U.S., and full-time businesspeople enrolled in executive MBA programs in Thailand and Turkey. The study is positioned within a fairly new stream that assesses patterns across countries, rather than differences between them, in a way that might be called “culture free.” The results show a generally positive influence between cultural ethical values and ethical intentions. The results also indicate that the positive effect of corporate ethical values on ethical intentions is greater for managers with low idealism and high relativism. We also discuss the implications of our results for managers of international businesses.
