On the International Linkages between Trade and Merger Policies*

In a three‐country model, this paper investigates linkages between merger incentives of exporting firms and the trade policy of an importing country. When exporting firms come from only one country, the tariff response of the importing country reverses the welfare effects of a merger in the exporting country. If there exist two exporting countries, a merger creates two types of conflicting international externalities. First, a merger in one exporting country increases profits of all firms. Secondly, non‐merged firms lose if the importing country is free to raise its tariff in response to a merger of foreign exporters.     

Publication Performance of Economists and Economics Departments in Turkey (1999–2003)

This is the first study evaluating the publication performances of economists and economics departments in Turkey. The international (article) publication performance of Turkish economic departments in general is found to be rather poor. There is a wide gap in particular between the top five universities and the economists affiliated to them and those outside the top five. The paper also provides evidence in favour of private higher education. The publication patterns of economists in Turkey are shown to be similar to those of their counterparts in the rest of the world.     

SHOULD WE CARE ABOUT THE COMPOSITION OF TAX‐BASED STIMULUS PACKAGES?

We investigate the effects of tax policy shocks on the U.S. economy over the 1972:3–2008:4 period within a structural vector autoregressive (SVAR) framework. Disaggregating tax shocks suggests that the positive output multipliers documented for total taxes by the previous literature are present only for indirect tax innovations. We also show that both labor and corporate taxes have similar effects on output, with labor tax multipliers being slightly larger in magnitude. The positive and negative responses of inflation following respectively corporate and labor tax shocks imply that former shocks work through aggregate supply, whereas the latter work predominantly through aggregate demand.

In search of efficient network structures: the needle in the haystack

Searching for efficient networks can prove a very difficult analytical and even computational task. In this paper, we explore the possibility of using the genetic algorithms (GA) technique to identify efficient network structures in the case of non-trivial payoff functions. The robustness of this method in predicting optimal networks is tested on the two simple stylized models introduced by Jackson and Wolinsky (1996), for which the efficient networks are known over the whole state space of the parameters’ values. This approach allows us to obtain new exploratory results in the case of the linear-spatialized connections model proposed by Johnson and Gilles (Rev Econ Des 5:273–299, 2000), for which the efficient allocation of bilateral connections is driven by contradictory forces that push either for a centralized structure around a coordinating agent, or for only locally and evenly distributed connections.

Price discrimination through multi-level loyalty programs

Loyalty programs often feature multiple rewards with different requirements; for instance, an airline offering a free domestic ticket for 10 K miles, and an international ticket for 20 K miles. This research focuses on the role of multi-level rewards as a segmentation and price discrimination mechanism: Multi-level rewards can increase firm profits when buyers differ in purchase frequency and/or time discount factor. We propose that a program with two rewards can be designed in such a way that (i) it is more profitable than a one-reward program, and (ii) buyers self-select. Light users prefer to receive the smaller reward two times over receiving the larger reward one time, even though the smaller reward is less than half of the larger reward. We show that the smaller reward helps the firm enlarge its base in the light user segment. We also compare multi-level programs with quantity discounts.     

Employment of the workforce with disabilities in the hospitality industry

A three-stage Delphi study was conducted with experts and professionals working in the fields of disability and hospitality in order to identify some basic principles with respect to employment of people with disabilities (PWD). The potential effects of employing PWD on safety, cost, efficiency, service quality and management were investigated. Potentials and limitations of people with different types and degrees of disabilities with regard to jobs in the hospitality industry were also questioned. A notable guiding principle emanating from this study is that hiring of employees should be based on merit, suitability and capability of the candidate, regardless of the presence or degree of disability. Another important outcome is that the job or task appointed to PWD should not deteriorate the disability. A common guideline expressed by the participants was that jobs which critically require a certain sense or ability are not suitable for PWD who do not possess this sense or ability even with the aid of technology or by other means. However, apart from such extreme and obvious cases, experts mostly agree that PWD can fulfill any task in the hospitality industry as long as their professional knowledge and skills fit those tasks.     

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.     

International Visibility of Balkan Economists in the Post-Socialist Era

During the socialist era, economists in the Balkan countries rarely published their work in the West due to political restrictions, methodological differences with the West, and inadequacy in Western languages. After the collapse of socialism, political barriers were lifted, a Western style of education in economics was adopted, and English began to be taught widely as the common language in the academic realm. The aim of this study is to discuss the impact of these policies on the publication performance of economists in the former socialist countries of the Balkans region. The results reveal that the number of international publications increased gradually over the post-socialist period and fast-reforming countries performed better than the slow movers.     

The tourism-led growth hypothesis: empirical evidence from Turkey

In the economic growth literature, the contribution of tourism to economic development has attracted great attention due to its significant roles as a source of foreign exchange earnings, creation of employment opportunities and an important source of public revenues in many countries. In this paper, we aim to analyse the empirical relationship between economic growth and tourism by employing different econometric techniques. First, we employed the Bound test approach developed by Pesaran, Shin, and Smith (2001, Bounds testing approaches to the analysis of level relationships. Journal of Applied Econometrics, 16(3), 289–326) in order to investigate the co-integration relationship between economic growth and tourism. Second, we used the Granger causality analysis for the 1998–2011 period and found evidence of a long-run uni-directional causality running from tourism to economic growth, but not vice versa. Our findings show that the Turkish case supports the tourism-led growth hypothesis (TLGH). Third, the autoregressive-distributed lag approach was employed in order to investigate the long-term and short-term static relationship between tourism and economic growth. The results show that tourism has a positive effect on gross domestic product and economic growth both in the long-term and short-term. Finally, the effect of tourism on economic growth was also investigated dynamically by employing the Kalman filter method. The findings of this method support the TLGH for Turkey.
