本研究探討各國智慧財產權保護和仿冒威脅程度的差異對美國影音軟體產品出口值的影響。資料為1997-2005年期間的panel data，分別採用由世界經濟論壇(WEF) 和瑞士洛桑國際管理學院（IMD)所發展之智財權指標，並以動態的GMM模型估計降低模型可能存在的內生性問題。實證結果在強仿冒威脅進口國方面，符合Smith(1999)的假說，亦即進口國智財權保護程度與美國影音軟體出口值成正比；但在弱仿冒威脅進口國方面，結果則與假說不符，產生與強仿冒威脅國家相同的結果。研究認為發生矛盾的原因是，影音軟體的仿冒過程遠較以往文獻研究的實體製造業產品容易得多，因此並不適用於之前的假設，再加上競爭者太多，導致廠商不敢大膽實施高價策略，使得市場獨占效果不顯著。 / This study investigates the effects of national differences in intellectual property rights (IPRs) protection and the degree of threat of imitation on U.S. audio-visual products’ exports. Using panel data for the period 1997-2005, we not only apply a longitudinal IPRs index developed by World Economic Forum (WEF) and International Institute for Management Development (IMD) , but also employ the technique of generalized method of moments (GMM) on dynamic panel model to control for endogeneity problem. The empirical results show that the stronger IPRs increase U.S. audio-visual products’ exports. For the strong threat-of-imitation countries , the results are the same as Smith(1999)；but for the weak threat-of-imitation countries , the results seems to contradict with theory predictions.We think the reason that audio-visual products is easier to copy than the manufacturing goods in the literature, so they do not suit for the hypotheses before. Therefore, the firms can’t apply a high-price strategy because of a lot of competitors, and market power effect is not dominant.

This thesis aims to reveal the magnitude of the income elasticity of health expenditure and the impact of non-income determinants of health expenditures in the Canadian Provinces. Health can be seen as a luxury good if the income elasticity exceeds unity and as a necessity good if the income elasticity is below unity. The motivation behind the analysis of the determinants of health spending is to identify the forces that drive the persistent increase in health expenditures in Canada and to explain the disparities in provincial health expenditures, thereby to prescribe sustainable macroeconomic policies regarding health spending. Panel data on real per capita GDP, relative price of health care, the share of publicly funded health expenditure, the share of senior population and life expectancy at birth have been used to investigate the determinants of Canadian real per capita provincial total, private and government health expenditures for the period 1975-2002. Dynamic models of health expenditure are analyzed via Generalized Instrumental Variables and Generalized Method of Moments techniques. Evidence confirms that health is far from being a luxury for Canada and government health expenditures are constrained by the relative prices. Results also cast doubt upon the power of quantitative analysis in explaining the increasing health expenditures.

This dissertation seeks to analyze, both theoretically and empirically, the impact of quality of governance on growth by looking at various dimensions of the concept of governance. We use a dynamic panel estimator and various indicators of governance to estimate the impact of governance on growth. Our empirical results suggest a positive and statistically significant impact of governance on growth. The second part of the analysis looks at a possible transmission mechanism of the effect of governance on growth through the composition of expenditures. As such, we estimate a seemingly unrelated regressions (SUR) model with shares of three functional categories of public expenditures – education, health, and defense – in total spending as the dependent variables. We find that high quality governance leads to a higher share of education and health expenditures and a lower share of defense expenditures in total expenditures. Further, we examine the impact of governance of public capital spending. Our empirical results from this analysis suggest that high quality governance is associated with a smaller share of capital expenditures in total expenditures

This paper investigates the impact of income inequality on grand total crime, larceny and violent crime by using the dynamic panel data of 20 cities and counties in Taiwan during 1998 to 2010. The empirical results show that income inequality has a significant positive impact on grand total crime, larceny and violent crime, but unemployment rate and the proportion of the population between 15 and 64 years old both have no significant influence on three kinds of crimes. Moreover the effect of the other explanatory variables is significant on at least one kind of crimes. The empirical results also support that the criminal expected utility theory, social anomic, disorganization, conflict and strain theories are helpful to explain the criminal behavior of Taiwan.

I introduce a novel approach for the empirical analysis of asset price comovement that relates the inter-firm textual similarity of news reports to their equity return correlation. I find that this measure of news similarity is just as important for predicting future cross-firm comovement as contemporaneous return correlation. This predictability remains after controlling for industry correlation, size, book-to-market, momentum, and price-decile correlation, index membership, and headquarters location, as well as institutional holding and analyst coverage. These results contribute to the growing literature examining the role of the media in financial markets, and provide empirical support for an alternative description of return comovement that does not depend on friction-based explanations such as "category," "habitat," or "information diffusion."

Contrary to conventional theory, a growing body of evidence suggests that economies with abundant natural resources perform badly in terms of economic growth relative to their resource poor counterparts—the so-called resource curse hypothesis. However, this general hypothesis is not robust. It clearly fails to account for the differing experiences of resource abundant economies. For instance, the theory, applied generally, offers no explanation as to why economies like Botswana and Norway have exceptional growth while Saudi Arabia and Nigeria have stagnated. Prompted by these experiences, the thesis investigates the circumstances under which the curse is more or less likely to exist. In particular, the thesis finds evidence that the major reason for the diverging experiences is the differences in the quality of institutions across countries. The thesis tests the hypothesis that the effect of resources on growth is conditional on the type and quality of institutions, by further building on Boschini, Pettersson, and Roine’s (2007) and Mehlum, Moene, and Torvik’s (2006b) influential works on the role of institutions in mitigating the resource curse. Advances are made by: (a) using a panel of up to 53 countries with different levels of development, institutional quality and natural resource abundance over the period 1984-2003; (b) applying a two-step system Generalised Method of Moments (GMM) estimation that accounts for biases associated with omitted variables, endogeneity and unobserved heterogeneity that potentially affect existing cross-country Ordinary Least Squares (OLS) growth results; (c) supplementing results of the commonly used International Country Risk Guide (ICRG) institutional performance indicators with those of institutional design indicators–that is, highlighting the role of electoral rules and form of government; (d) using an institutional quality measure that is more related to financial institutions than just economic or political institutions; (e) using a resource abundance indicator that focuses on non-renewable resources alone rather than the ones commonly used in the literature that include renewable resources, which are inappropriate. The key hypothesis that natural resource economies are not destined to be cursed if they have good institutions is confirmed by the empirical results of the thesis. Specifically, the results suggest that (a) adopting a democratic regime is better than a non-democratic one, in terms of generating growth from resource abundance (b) the electoral rules that a country adopts matter, i.e. having a democratic proportional rather than a democratic majority regime increases the growth benefits of resource abundance (c) as far as the form of government adopted is concerned, a democratic parliamentary rather than a democratic presidential regime generates more economic growth from its abundant natural resource (d) a well functioning banking sector induces more (resource abundant generated) growth and capital accumulation. Therefore, the lessons for policy makers who struggle to overcome the impediments to economic development that potentially accompany the “curse of resource abundance” are the need to develop and maintain better institutions and adopt improved management strategies of the financial proceeds forthcoming from such abundance.

We analyze how the impact of a change in the sovereign debt-to-GDP ratio on economic growth depends on the level of debt, the stress level on the financial market and the membership in a monetary union. A dynamic growth model is put forward demonstrating that debt affects macroeconomic activity in a non-linear manner due to amplifications from the financial sector. Employing dynamic country-specific and dynamic panel threshold regression methods, we study the non-linear relation between the growth rate and the debt-to-GDP ratio using quarterly data for sixteen industrialized countries for the period 1981Q1-2013Q2. We find that the debt-to-GDP ratio has impaired economic growth primarily during times of high financial stress and only for countries of the European Monetary Union and not for the stand-alone countries in our sample. A high debt-to-GDP ratio by itself does not seem to necessarily negatively affect growth if financial markets are calm. (authors' abstract) / Series: Department of Economics Working Paper Series
