This thesis complements current studies by focusing on developed OECD countries as they are the major sources and recipients of world FDI and current studies relating to developed countries using aggregate country FDI data are limited. This study empirically tests the determinants of FDI inflows and outflows and their relationship with economic growth using 2SLS simultaneous equations model between 1981 and 2008 for a sample of 20 developed OECD countries. The empirical findings suggest that FDI inflows do not contribute to economic growth in the host country and economic growth positively affects FDI inflows. In addition, trade openness and flexible employment protection legislation in the host country attract FDI inflows. In terms of FDI outflows, the results show that FDI outflows reduce economic growth in the home country, while economic growth in the home country increases FDI outflows. Moreover, high past level of outward FDI stock, trade openness, low labour cost and currency depreciation in the home country provide incentives for domestic firms to invest abroad. Therefore, this study does not support offering special incentives to foreign investors to attract FDI inflows or offering promotional policies to domestic firms to encourage FDI outflows. Instead, government should provide incentives for domestic investment and other sound policies to increase economic growth, which in itself provides a good environment to attract FDI inflows and to encourage FDI outflows. Keywords: FDI inflows, FDI outflows, two stage least squares simultaneous equations, economic growth, labour market flexibility.

There are many reasons for companies to hold real estate, including for operating business, production, sales, and providing services. Previous researches show that corporate real estate (CRE) is an important part of company assets, and it will affect stock returns and risk of company. The main object of this study is to investigate the impact of changes in CRE on stock returns and risk of company in Taiwan. Moreover, this study analyzes how CRE affect toward different industry during each business cycle period. Then, we provide some suggestions to stockholders and managers. The data set from 1992 through 2011 in Taiwan stock market, the relationship between CRE and stock returns and risk are analyzed using two stage least squares regression model. The empirical results show that, on average, higher CRE appears to be associated with higher abnormal return performance and higher total risk. On the other hand, CRE show negative impact on business operation such as lower adjusted return on assets and higher risk of bankruptcy. Furthermore, CRE factor is associated with higher abnormal return performance and higher firm value when company with small asset size, high P/E ratio or newly establish characters. Results also indicate that the impact of CRE on firm¡¦s stock price and risk depend on industries, business cycle period, and firm characters. CRE show negative impact on Textile, Tourism, and Trading and Consumers' Goods Industry. In Food Industry, higher CRE factor is associated with lower system risk and positive impact on business operation.

The prospects for the next Generation - whether young people, regardless of their backgrounds, have equal chances of social success - pose a momentous problem for modern societies. Inequality of opportunity, often reflected by social immobility, is a threat to the egalitarian promise and the stability of your society. This work argues that social capital transmission plays an important role for the chances of social success in Western societies. For the example of Germany, it is reasoned that weak social capital environments deepen existing disadvantages. Even though all levels of education are easily accessible and affordable, Germany has one of the lowest levels of educational mobility among the industrialized countries of the world. Problems appear to be systematic, since the decision regarding entry into higher secondary education is made at early age and is left, in most cases, with the parents, who rely on their own educational trajectory. Outside of the school environment, differences in social capital inheritance explain educational immobility. With the use of the German Socio-Economic Panel survey from 1984 to 2014, various analyses about the relation between social capital and educational success are performed. Social capital, which is helpful for educational and social success, clearly depends on the educational family background. This indirect link has been disregarded in past contributions. Alternative forms of schooling, such as comprehensive and all-day education, as well as a delay of the decision regarding entry into higher education, could help improving unequal social capital inheritance.

This thesis studies inference to the complier treatment effect denoted LATE. The standard approach is to base the inference on the two-stage least squares (2SLS) estimator and asymptotic Neyman inference, i.e., the t-test. The paper suggests a Fisher Randomization Test based on the t-test statistic as an alternative to the Neyman inference. Based on the setup with a randomized experiment with noncompliance, for which one can identify the LATE, I compare the two approaches in a Monte Carlo (MC) simulations. The results from the MC simulation is that the Fisher randomization test is not a valid alternative to the Neyman’s test as it has too low power.

The healthcare labor market has experienced some significant changes in the last half century, including the establishment of Medicare and Medicaid in 1965, the emergence of managed care in the 1980s, and the worldwide mobility of labor encouraged by globalization. Currently, more than 25% of physicians working in the U.S. are foreign-born. The existing body of literature related to the impact of immigration on local wages has to date found conflicting results. The purpose of this research is to evaluate the impact of immigration of foreign physicians on local physician wages. This study employs physician survey data from the AMA Physician Masterfile for the years 1997 through 2007 combined with wage data published by the Bureau of Labor Statistics and data from other government sources. Several econometric models are employed to analyze the wage impacts of immigration, including ordinary least squares, fixed effects, two-stage least squares and a first-difference approach to control for endogenous location choice. The results of this study provide evidence that in the short-run, the impacts of immigration of physicians on area wages is small but positive. In the long run, however, wages adjust and the impact becomes negative and statistically significant, although the magnitude of the impact of a one percentage point increase in the share of immigrant physicians in an area is less than 0.2%. The negative wage effects of immigration tend to be larger for foreign-born physicians educated in the U.S. compared with foreign-born international medical graduates. The study also finds evidence that the negative effects of immigration tend to be offset by outflows of the lowest paid native physicians. Furthermore, physicians tend to locate in areas where wages are already higher, and foreign-born physicians are more likely than their native counterparts to work in larger cities as opposed to rural areas. The research has important policy implications in the presence of current debate over immigration law and healthcare reform and in an era of increasing mobility of labor due to globalization.

The primary objective of this study was to develop an empirical model that accounts for factors affecting the demand for international tourist hotels, and that enables demand estimation and projection of demand, in the context of the metropolitan Seoul area. Models were hypothesized to explain market behavior of selected segments of the hotel industry. Demand Model I accounted for international hotel demand incorporating such explanatory variables as price, trade volume and events. Both demand and price were treated as endogenous variables and the time-dependent error processes were all examined. Demand Model I was further expanded by incorporating segmentation variables. The inclusion of segmentation variables into the model in Demand Model II enabled the analysis of the interdependence of market segments that affects demand. Along with the incorporation of a time series structure, a system of equations was employed for Demand Model II. The results indicated that the explanatory variables, which were own price, the number of events and the volume of trade, had a significant impact on international hotel demand. The results from the demand equations also revealed that the demand for a segment is significantly influenced by price and demand for other segments. A cross-segment substitution effect on the demand side is quite relevant for the international lodging market in Seoul and demand for a market segment fluctuates in the same direction as the total market demand changes. From the price equations, the market price of lodging services was found to be related to demand and supply influences simultaneously. The results also indicated that seasonality and economic factors, such as exchange rates and consumer price index, have significant influence directly on international lodging prices. Such factors also were found to have indirect effects on the demand level. / Ph. D.

Cette thèse présente trois chapitres qui mobilisent un cadre d’analyse évolutionniste et qui étudient empiriquement la relation « innovation-performance » à partir de données CIS. Nous souhaitons montrer que les sources de l’innovation et les méthodes d’appropriation varient en fonction des secteurs d’activité et des stratégies d’innovation des firmes. Dans un premier temps, nous décrivons les tendances de l’innovation à partir de quatre vagues d’enquêtes CIS (1994-2006) et nous analysons la persistance de l’innovation sur un échantillon de 431 firmes avec une régression logistique binaire. Nous montrons que la persistance de l’innovation est plus élevée pour les firmes qui innovent en produits car ces firmes sont contraintes d’investir de manière continue dans des projets d’innovation pour rester compétitives. Les firmes qui innovent en procédés sont moins persistantes car leur stratégie est plus orientée vers des ajustements de la qualité des produits ainsi que vers l’amélioration des processus de production. Les deux derniers essais explorent avec la méthode des doubles moindres carrés le lien innovation-performance économique sur un échantillon de 7 742 firmes portant sur la période 2002-2005. Nous expliquons que la source principale de l’innovation des firmes à « forte intensité scientifique » est la R&D, d’une part, et que les méthodes d’appropriation des rentes de l’innovation passent par l’acquisition d’actifs complémentaires (tels que l’utilisation combinée de titres de propriété intellectuelle et de secrets de fabrication), d’autre part. En revanche, les firmes dans les autres catégories (notamment celles à fortes économies d’échelle) fondent leurs avancées technologiques sur des sources externes de l’innovation telles que les concurrents, les fournisseurs et les utilisateurs avancés. De plus, ces firmes utilisent de manière plus importante des méthodes d’appropriation commerciale telles que les marques ou les stratégies marketing, car leurs produits sont moins exposés au risque d’imitation certes, mais aussi parce qu’elles sont sensibles aux changements de coûts. / This thesis is structured in three essays based on evolutionary theoretical grounds and provides empirical evidence from CIS. It aims at showing that the sources of innovation and the appropriation of innovation rents vary in function of firms’ activities and innovation strategies.In essay 1, we describe four waves of CIS, covering the period 1994-2006 and we study persistent innovation behavior with a discrete choice model on a data set of 431 firms. We find that innovation persistence is more important for product innovators because they need novel products to be more competitive and therefore enrich their base of knowledge continuously. By contrast, process innovators are less persistent because innovation strategy is less “market” oriented and intends to meet quality or production adjustments. The two last essays explore with the two stage least squares method how firms benefit economically from their innovations on a sample of 7 742 firms, on the period 2002-2005. We show that science-based firms rely more on R&D investments to develop their products and maintain their leads by acquiring complementary assets, i.e. they use mixed methods to appropriate the rents of innovation (the combined use IPRs and strategic methods for instance secrecy). By contrast, firms in other categories (for instance firms using cost-cutting strategies) draw more on external sources of knowledge coming either from suppliers or advanced users. Additionally, these firms use more extensively trademarks or non technological methods of appropriation (as marketing devices), because they are less exposed to potential imitation and because they are price sensitive.
