Neighbors and the evolution of the comparative advantage of nations: Evidence of international knowledge diffusion?

The literature on knowledge diffusion shows that knowledge decays strongly with distance. In this paper we document that the probability that a product is added to a country's export basket is, on average, 65% larger if a neighboring country is a successful exporter of that same product. For existing products, growth of exports in a country is 1.5% higher per annum if it has a neighbor with comparative advantage in these products. While these results could be driven by a common third factor that escapes our controls, they align with our expectations of the localized character of knowledge diffusion.     

Brand Turkey: Liminal Identity and its Limits

Since the 2000s, Turkish policymakers and private sector interests have combined representations of Turkey as both Western and Eastern with a branding approach to identity in foreign policy, trade and investment promotion, and cultural sector activities. This article analyses how the commodification of its liminal identity as a dual identity allowed Turkey to invoke different aspects of its identity in the West and the East in ways that catered to both audiences and enabled the pursuit of different political and economic objectives. However, the article also notes how this branding strategy was limited by the national identity debates and dominant geopolitical discourses that continued to situate the West and East as mutually exclusive and binary opposite identity markers. Overall, the case of Turkey underscores the complex relationship between branding, identity, and discourse, which has thus far received scant attention in the literature.     

Business Cycle Synchronization of Turkey with the Eurozone and the United States: What Has Changed Since 2001?

Using wavelet methodology, we make a detailed spectral analysis of the business cycle synchronization of the Turkish economy with the eurozone and the United States. We take into account the dramatic change in the main economic indicators in the Turkish economy after the 2001 financial crisis. We find that the correlation of Turkish cycles with the cycles of the eurozone and the United States increased substantially after 2001. Moreover, the correlation of the Turkish cycles with the U.S. cycles is not lower than that with the euro cycles after 2001. Accordingly, analyzing the effect of international developments should not be confined to the trade channel. We submit that capital flows offer a reasonable explanation for the high correlation with the United States.

Heterogeneity in the determinants of length of stay across middle age and senior age groups in thermal tourism

ABSTRACT

Water has been seen as a healing source of life for centuries. Even the placebo effect of thermal therapies increases consumers’ well-being. Especially with easy traveling options demand for thermal therapies are on the rise. Users of thermal therapies are mostly composed of seniors. Even though age groups in the senior market have heterogeneous needs, managers assume them to be homogenous. Measuring thermal tourism demand by the length of stay, this study analyzed the determinants affecting the length of stay of older thermal tourists. The length of stay is predicted to have been affected by age, purchasing power, physical distance, and seasonal preferences. Even though all of the above have an effect on the length of stay, we find that age is the main determinant deciding the duration. These results may serve as a starting point for policymakers and tourism managers to tailor strategies to increase income streams associated with length of stay.     

MNEs and wages: The role of productivity spillovers and imperfect labor markets

Disentangling the labor market implications of increased foreign capital flows remains important. This paper provides a unifying framework allowing to study the wage implications of multinational enterprise (MNE) activities, pointing to the importance of controlling for both labor market imperfections and productivity spillovers from foreign to local firms. Results show that increased MNE activities increase average wages in the local economy while contributing to a larger wage dispersion between the MNE and local firms. While the results pertaining to average wages depends heavily on the frictions in the labor market, how much the wage dispersion alters also depends on the extent of productivity spillovers from the MNEs to the local firms and the complementarity between domestic and foreign capital.     

Environmental Policy with Endogenous Technology from a Game Theoretic Perspective: The Case of the US Pulp and Paper Industry

The merits of different types of regulatory tools in eliminating pollution and at the same time inducing innovation have long been an interest of researchers in both environmental economics and industrial organization. Although there is a substantial theoretical literature investigating the potential for various environmental policies to attain these dual goals, this is a challenging empirical problem because every industry has its own inherent characteristics that play an important role in determining the performance of different regulatory tools. The majority of the work to date focuses on pollution abatement while leaving pollution prevention understudied. In most of the literature firms are also assumed to be symmetric. Asymmetries among firms add another degree and level of complexity to their strategic interactions, and affect the performance of different regulatory tools. This paper investigates the performance of two alternative regulatory tools, an emissions performance standard and an emissions tax, in reducing pollution and inducing pollution prevention and abatement R&D in the US pulp and paper industry. We construct a model representing the industry in an asymmetric Cournot duopoly framework, calibrate the model to disaggregated industry data, and run scenarios to replicate the behavior of the firms in an imperfectly competitive output market. Our results suggest that pollution prevention R&D can respond quite differently than abatement R&D to different policy instruments. The results indicate that R&D spillovers among firms play crucial role in technology development and strategies of the firms. Our results also suggest that strategic interactions between firms in an imperfectly competitive industry can have significant impacts of the levels of both types of R&D.      

Hierarchical multimodal hub location problem with time-definite deliveries

Hierarchical multimodal hub location problem is a cost-minimizing hub covering problem where two types of hubs and hub links, accounting for ground and air transportation, are to be established, while ensuring time-definite deliveries. We propose a mixed-integer programming formulation and perform a comprehensive sensitivity analysis on the Turkish network. We show that the locations of airport hubs are less sensitive to the cost parameters compared to the locations of ground hubs and it is possible to improve the service quality at not much additional cost in the resulting multimodal networks. Our methodology provides the means for a detailed trade-off analysis.

Dyadic Operationalization in Business Relationships: The Empirical Example of Marketing-Purchasing Collaboration

Purpose: The purpose of this paper is to explore whether dyadic operationalization within business relationships is feasible and sensible in a rigorous way. It aims to introduce quantitative operationalizations of business relationship characteristics from both monadic and dyadic datasets, and to introduce aggregation techniques for utilizing the richness of dyadic data. It compares and contrasts the effectiveness of different techniques in terms of explaining business relationship phenomena, using an empirical exemplification.

Methodology/Approach: The paper reviews the relevant literature and summarizes various dyadic operationalization and aggregation approaches. It furthermore illustrates such operationalization and aggregation by utilizing an empirical example. A nomological model of marketing-purchasing collaboration is developed and tested based upon internal dyadic data. Using alternative model comparisons, we contrast several different ways of operationalizing dyadic data (combined, dyadic, and dyadic with asymmetry), and compare the outcomes utilizing structural equation modeling.

Findings: The study of business relationships typically makes use of a variety of data types, ranging from simple monadic to perceived dyadic, through to rigorous dyadic data. The various aggregation methods include value, asymmetry, and directional asymmetry approaches. Pertinent sub-constructs are developed based on these aggregation methods and relevant hypotheses incorporating and reflecting on the role of the sub-constructs are suggested to develop a more meaningful and rich quantitative analysis of business relationship phenomena.

Research Implications: This paper explores the different ways in which data assessing the relationship between two interacting parties can be operationalized. Dyadic operationalization within the context of business relationships is sensible and recommended. Researchers can adopt approaches to conduct dyadic data operationalization including data collection methods such as perceived dyadic and rigorous dyadic. They should benefit from rich dyadic aggregation approaches such as value, asymmetry, and directional asymmetry, noting the strengths and weaknesses of each approach discussed in this paper.

Practical Implications: Businesses are recommended to increase customer orientation and marketing-purchasing interaction to improve collaboration between marketing and purchasing departments and thus their overall performance. Businesses should also develop an alignment between the collaboration perceptions of the involved departments, and note that perceptual symmetry improves collaboration. Perception matching in a dyadic relationship plays a role in enhancing the overall firm performance. Managers should note that all involved parties’ perspectives are to be included to ensure a positive and collaborative liaison. An all-encompassing attitude and perspective (as opposed to an asymmetric, unbalanced one) ensures an effective relationship.

Originality/Value/Contribution of the paper: The contribution of the research lies in outlining different ways to accomplish more insightful analytics regarding data operationalization, and their different strengths and weaknesses in terms of explaining relationship characteristics, and therefore enriches research on business relationships by making better sense of quantitative dyadic data.
