In this study, we examine the relationship between foreign direct investment (FDI) and terrorist incidents that took place in Turkey during the period 1991:12 to 2003:12. By doing so we contribute to the literature by allowing for a possible nonlinear relationship between terrorism and FDI. The data used to measure the intensity of terrorism were collected from a major newspaper of Turkey, and therefore is limited to the direct signals given to the market. Empirical evidence from both linear and non-linear models confirms that terrorism has a large negative impact on foreign direct investment. As far as the results of the nonlinear model estimation are concerned, the impact of terrorism on FDI is estimated to be more severe during periods of high terrorism where the intensity of terrorism passes a certain threshold level. This threshold level can be interpreted as a warning ‘signal’ that FDI may decrease severely and thereby can be used by policy makers to design effective policy measures and by potential investors as an indicator of a country’s risk profile

This paper analyses the short-and long-term relationships between the transportationcommunication capital and the output for Turkey. The study applies a Cobb-Douglas production function under the assumption of constant returns to scale and employs co-integration analysis by estimating a vector error correction model (VECM). As a result of the VECM estimation, one co-integrating relationship is detected. The results based on the impulse response function analysis imply that per labour transportation-communication capital appears both to have been a crucial input in the Turkish productive process and to have had a positive crowding in effect on the per labour non-residential total capital formation. Moreover, the results support the argument that the transportation-communication capital has a lagged impact on economic growth. The long-term accumulated elasticity of output to transportation-communication capital has been found to be 0.59. The long-term accumulated marginal product was also calculated. It implies that a 1 Turkish Lira increase in per labour transportation-communication capital results in a long-term rise of 1.45 Turkish Liras in per labour output. All these findings suggest that transportation-communication capital may be a powerful tool for policy-makers to promote long-term per labour real output growth in Turkey.

The aim of this study is to analyze the relationship between labor productivity and R&D expenditures. We have tested this relationship using a panel of 22 OECD countries that covers the period 1991-2003. A Cobb-Douglas production function was estimated in growth form where physical capital, knowledge capital, human capital, and labor stock were included as the factors of production. The estimation results that also controlled for the effect of openness, and R&D spillovers implied a positive long-run R&D elasticity with respect to labor productivity growth. This result is robust to an alternative model where capital to labor ratio and labor variables are excluded. In this new model, the coefficient of the international trade variable included to account for openness was found to be positive. Keywords
