Foreign Direct Investment and Technology Spillovers in the Turkish Manufacturing Industry

Technology spillovers from foreign to domestic firms in emerging economies are considered to be the most important channel through which Foreign Direct Investment (FDI) influence the host economy. Empirical evidence about the existence, magnitude and direction of FDI-related spillovers in these countries is contradictory pointing to the necessity of conducting more econometric studies using firm-level data. We conduct an econometric analysis to assess the impact of FDI-related horizontal technology spillovers on output growth of domestic firms in the Turkish manufacturing industry over 2003-2006. When a broad definition of foreign ownership is adopted, our findings suggest that horizontal spillovers occur from foreign to local firms in the sector of activity. Export-oriented firms do not benefit from these spillovers in contrast to firms producing mainly for the domestic market. However, when foreign ownership is defined according to whether the minority or majority of capital is detained by the foreign partner, horizontal spillovers seem to originate from foreign firms with majority or full foreign ownership while no such effect is associated with minority-owned foreign firms.Foreign Direct Investment (FDI), multinational corporations, foreign ownership, productivity, technology spillovers, knowledge spillovers, horizontal spillovers, Turkey.

Nanotechnology research in Turkey: A university-driven achievement

We deal with nanotechnology research activities in Turkey. Based on publication data retrieved from ISI Web of SSCI database, the main actors and the main characteristics of nanotechnology research in Turkey are identified. Following a brief introduction to nanoscience and nanotechnology research, it goes on with a discussion on nanotechnology related science and technology policy efforts in developing countries and particularly in Turkey. Then using bibliometric methods and social network analysis techniques, this paper aims to understand the main actors of the nanoscale research in Turkey and how they collaborate across institutes and disciplines. The research indicates that there has been an exponential growth in the number of research articles published by Turkish nanoscience and nanotechnology (NST) scholars for the last ten years. However, the analysis of the main characteristics of nanotechnology research carried out at Turkish universities indicates some drawbacks and barriers to the future development of nanotechnology research in Turkey. These barriers are (i) a high concentration of nanoscale research at certain universities; (ii) low level of interdisciplinarity; (iii) a large number of universities which are not well connected to other universities in the field, and finally (iv) low level of international collaborations. Finally, science and technology policy implications of this research are discussed in the conclusion.Emerging technologies nanotechnology, nanoscience, scientific publications, SSCI, bibliometric data, social network analysis, collaborations, interdisciplinarity, science and technology policies, emerging economies, Turkey.

Technology Transfer in the Global Automotive Value Chain. Lessons from the Turkish Automotive Industry

The automotive industry is one of the main contributors to value added, employment and exports of the Turkish economy and it has undergone major changes since the mid-nineties. Most of the automotive manufacturers in Turkey are either joint ventures or wholly-owned affiliates of multinational companies. Literature on global value chains point to the possibility of technology transfer occurring through backward linkages from automotive manufacturers to their suppliers. We test for the existence and the importance of different types of knowledge and technology transfer mechanisms in the Turkish automotive industry. In addition, characteristics of local suppliers impacting on these transfers and their impact on firm performance are analyzed.Asurvey based on a detailed questionnaire was administered to production/R&D managers of the 158 automotive suppliersoperating in Turkey in 2010. Logistic and ordinal regressionsare used to examine the aforementioned issues. Findings confirm the existence of transfers from customers to their local suppliers on co-design and co-development activities, designing of production tools, development/improvement of quality control methods, cost reduction and design of materials. In addition, econometric analysis points to the fact that these transfers exert a positive effect on the performance of supplier firms.Automotive Industry, Knowledge and Technology Transfer, Multinational Companies (MNCs), Foreign Direct Investment (FDI), Innovation, Research and Development (R&D)

Analyzing R&D Activities of Foreign Enterprises in Emerging Economies. Lessons from Turkey

Emerging economies have played an important role in the internationalization of R&D activities at least since the 1990s. Turkey, an emerging economy and at same time an accession country to the European Union which signed a Customs Union Agreement with the EU already in 1995, is no exception. In-depth face-to-face semi-structured interviews were conducted with R&D directors of 26 multinational companies operating in Turkey –with headquarters located in France, Germany, Italy, Japan, Switzerlandand USA- in the informatics, automotive, electronics and pharmaceutical industries. Data and qualitative information obtained through these interviews are then used to analyze those factors theory points to as being major determinants of foreign R&D in emerging economies. The emphasis is on the (i) motivations of foreign enterprises for launching new R&D activities or extending existing ones (ii) restrictions of different kind they encounter in doing so (iii) their reactions with respect to FDI promotion policies and public R&D support incentives implemented by Turkish policy makers, and (iv) advantages/disadvantages of Turkish economy as an R&D location in comparison with other emerging economies. A number of policy recommendations for attracting more foreign R&D in Turkey and integrating them with the Turkish national innovation system are advanced.Research and development (R&D), internationalization of R&D, R&D offshoring, multinational companies, national innovation systems, case studies, semi-structured interviews

Individual and Organizational Aspects of University-Industry Relations in Nanotechnology: The Turkish Case

Emerging nanotechnologies bring a new challenge for developing countries to improve knowledge and technology transfer between universities and firms. In developing countries, weaker ties between academia and the industry seem to be one of the main barriers to the dissemination of nanotechnology innovations. This study aims to understand individual and organizational factors affecting university-industry interactions in emerging nanotechnologies in a developing country context, namely Turkey. For this study, 181 questionnaires were collected from a sample of nano-science and nanotechnology academics who are currently employed by Turkish universities. The results provide that informal / interpersonal and research-related interactions are the most common forms of relationship between academics and firms. On the other hand, the study provides a useful insight to understand how human and social capitals of university-scientists as well as organizational resources/ capabilities influence the formation of links between universities and the industry.Nanotechnology, nanoscience, emerging technologies, technology transfer, university-industry relations, science and technology policies, probit model, disproportionate stratified sampling, emerging economies, Turkey.

Non-relativistic Lee Model on two Dimensional Riemannian Manifolds

This work is a continuation of our previous work (JMP, Vol. 48, 12, pp. 122103-1-122103-20, 2007), where we constructed the non-relativistic Lee model in three dimensional Riemannian manifolds. Here we renormalize the two dimensional version by using the same methods and the results are shortly given since the calculations are basically the same as in the three dimensional model. We also show that the ground state energy is bounded from below due to the upper bound of the heat kernel for compact and Cartan-Hadamard manifolds. In contrast to the construction of the model and the proof of the lower bound of the ground state energy, the mean field approximation to the two dimensional model is not similar to the one in three dimensions and it requires a deeper analysis, which is the main result of this paper.Comment: 18 pages, no figure

Ultimate strength of cold-formed steel z-purlins

INTRODUCTION Cold-formed steel structures are being widely used in various forms of construction such as industrial plants, gymnasiums, hangars and metal buildings. One important feature of metal building construction is the use of light gage roof panels connected to purlins, particularly of the Z-section. This section is, besides the channel-section, the simplest two-flange section which can be produced by cold-forming. The purlins have span lengths of 20 to 25 feet, generally made continuous over the building rigid frames by nesting. Construction details vary from manufacturer to manufacturer. The purlins available would typically have prepunched holes for connection of various types of bracings, overlapping connections, etc

Geometric Quantization on the Super-Disc

In this article we discuss the geometric quantization on a certain type of infinite dimensional super-disc. Such systems are quite natural when we analyze coupled bosons and fermions. The large-N limit of a system like that corresponds to a certain super-homogeneous space. First, we define an example of a super-homogeneous manifold: a super-disc. We show that it has a natural symplectic form, it can be used to introduce classical dynamics once a Hamiltonian is chosen. Existence of moment maps provide a Poisson realization of the underlying symmetry super-group. These are the natural operators to quantize via methods of geometric quantization, and we show that this can be done.Comment: 17 pages, Latex file.

Large N limit of SO(N) scalar gauge theory

In this paper we study the large $N_c$ limit of SO(N_c) gauge theory coupled to a real scalar field following ideas of Rajeev. We see that the phase space of this resulting classical theory is Sp_1(H)/U(H_+) which is the analog of the Siegel disc in infinite dimensions. The linearized equations of motion give us a version of the well-known 't Hooft equation of two dimensional QCD.Comment: 16 pages, no figure

Finitely Many Dirac-Delta Interactions on Riemannian Manifolds

This work is intended as an attempt to study the non-perturbative renormalization of bound state problem of finitely many Dirac-delta interactions on Riemannian manifolds, S^2, H^2 and H^3. We formulate the problem in terms of a finite dimensional matrix, called the characteristic matrix. The bound state energies can be found from the characteristic equation. The characteristic matrix can be found after a regularization and renormalization by using a sharp cut-off in the eigenvalue spectrum of the Laplacian, as it is done in the flat space, or using the heat kernel method. These two approaches are equivalent in the case of compact manifolds. The heat kernel method has a general advantage to find lower bounds on the spectrum even for compact manifolds as shown in the case of S^2. The heat kernels for H^2 and H^3 are known explicitly, thus we can calculate the characteristic matrix. Using the result, we give lower bound estimates of the discrete spectrum.Comment: To be published in JM
