Foreign direct investment (FDI) is a source that improves the competiveness of the host country which can be further utilised to develop the country’s own resources and capabilities. In addition, non-affiliated local firms that do not have a foreign partner improve their performance due to the spillover effects gained either through the sharing of resources, learnings or due to the increase in competition. As such, FDI is seen as an important economic growth driver in developing economies since these economies struggle to compete in the global economy.The objective of this research is to determine whether foreign ownership in a developing economy is beneficial in terms of national competiveness; reducing the income gaps; improving employment opportunities; improving the financial performance of an acquired local firm and if the foreign parent introduces new technologies into the economy. Due to the mining- and manufacturing sector being the main recipients of FDI in South Africa and both having similar operations specifically being high capital and labour intensive, these sectors were chosen for the purpose of this research. The data sample was analysed using multiple regression as it is a flexible method of data analysis that may be appropriate whenever a quantitative dependent variable needs to be examined to find a relationship with two or more independent or explanatory variables.The results indicate significant benefits for the host economy in attracting FDI into the country. The benefits seemingly outweigh the costs and the presence of Multinational Corporations (MNCs) in South Africa will help it in elevating some of the socio-economic challengers like high unemployment rate and the shortage of skills through resource sharing with the MNCs. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

This thesis examines the dependence structures between commodity futures and corresponding commodity producer equity indices in bearish, bullish and normal market conditions. We study commodity futures and producer indices in the energy, precious metals, gold and agriculture commodity markets using daily return data that ranges from 16 December 2005 to 28 June 2019. We employ the cross-quantilogram approach developed by Han et al. (2016) to examine dependence structures in the full quantile range, which represents different market states. Furthermore, we control for different lag structures, uncertainties and time-varying dependence structures. From our results we conclude the following: 1) There are time-varying asymmetric and symmetric dependencies in different commodity markets. There is asymmetric dependence between commodity futures and producer indices in the precious metals, gold and agricultural markets. In the oil market, the relationship is symmetrical. No relationship is found in the natural gas market. 2) Heterogenous dependence structures are identified in the gold, precious metals and agricultural commodity markets. The oil market uncovers homogenous dependence structures. 3) The observed spillover in all markets occur in the very short run, at one day, and dissipates after a week and additionally after a month. Our results provide new information regarding commodity diversification attributes which can be useful to investors. Our results also provide important policy implications: Since volatility spillovers between commodity futures and producer indices may deter investors from including commodities in their portfolios, as they might lose their diversifier qualities, it is important to enforce policies that will prevent the spillovers between the assets. Further, regulations of the commodity futures markets could be an alternative to reduce the spillovers.

This dissertation consists of three essays that study the role of information acquisition and processing in health decision-making. Each chapter underscores the ways in which new information shapes the choices of health providers and consumers. Understanding these responses sheds light on critical health policy problems, including the potential overuse of low-value health services, gaps between medical evidence and practice, and inequitable access to high-value health services. The first essay studies the role of a consumer’s family network in the formation of their risk perceptions. I assess whether people correctly interpret new risk information communicated through household health events and analyze how these responses impact household welfare. Individuals respond to new diagnoses in ways most consistent with individual reevaluations of health risk rather than other possible explanations. To assess welfare implications, I estimate a structural model of health choices in which individuals learn about risk after health events reveal information. I find that consumers over-respond to recent, salient health events by over-weighting their risks ex-post. This leads to individual and social welfare losses, and suggests that aiding consumers in interpreting health risk information should be an important aim of health literacy policies. The second essay explores how health providers respond to information about innovations in mental health treatments, paying particular attention to the heterogeneous adoption costs of different practices. I compare the impact of continuing education on takeup across innovations that incur learning costs (psychotherapy) and those that do not (psychopharmacology). I use a novel extension of an estimator proposed by Calvi et al. (2021) to estimate a dynamic treatment effect in the presence of classification error. Therapists respond more to education when learning costs are negligent, being about three percentage points more likely to write new prescriptions following a conference. The third essay assesses the tradeoff between adopting novel medical technologies and achieving health equity. I study the adoption of transcatheter valve replacement surgeries in Medicare patients; these surgeries disrupted the supply of medical interventions from cardiothoracic surgeons to interventional cardiologists. This transition led providers to adjust practice styles along two margins: medium-risk patients became more likely to receive surgery, and low-risk patients received fewer medical interventions overall. I incorporate these findings into a model of physician decision-making, showing that both the expansion of high-intensity intervention and the crowd-out of low-intensity treatment can be rationalized by the presence of technological spillovers. The model further highlights that crowd-out may be inequitably distributed across the patient population when treatment appropriateness is not directly observed. I validate these predictions in my setting, showing that technology adoption resulted in disproportionately high barriers to care for low-income patients.

The major themes of this thesis are the impact of Intellectual Property (IP) systems on foreign direct investment spillovers and bilateral FDI flows. This thesis consists of three empirical studies. The first study integrates in the existing theoretical frameworks the distinct effect of the public IP enforcement element of IP systems on FDI horizontal spillovers. By employing a meta-analysis approach and the ordered probit model estimation technique, it finds that the strength of public IP enforcement in a host country has a positive effect on FDI horizontal spillovers but it dampens the positive effect of IP law protection on FDI horizontal spillovers when it becomes too strong. The second empirical study examines the impact of IP systems on FDI vertical spillovers. This study employs a similar conceptual and empirical approach and finds that the strength of public IP enforcement has a positive effect on FDI vertical spilloversbut a negative moderating effect on the relationship between the strength of IP law protection and FDI vertical spillovers. In the third empirical study, a gravity model is applied to test the effect of IP systems on bilateral FDI flows in OECD countries. Using the Poisson pseudo-maximum-likelihood, it finds both the strength of IP law protection and the strength of public IP enforcement to have a positive effect on bilateral FDI flows. The broad implication of these findings is that countries should strengthen both their IP law protection and enforcement but apply appropriate measures to mitigate the negative effect resulted from excessive IP protection.

This thesis consists of three empirical essays in financial economics, with particular focus on the European Union and the Eurozone. The thesis investigates topics related to market liquidity and integration. In particular, it covers the transmission of liquidity shocks across Eurozone markets, the role of market liquidity in the repurchase programme and integration of Eurozone economies in terms of welfare gains from trade. Liquidity and integration have received considerable attention in recent years, particularly within the context of global financial and macroeconomic uncertainty over the last decade. In the first empirical essay, we investigate static and dynamic liquidity spillovers across the Eurozone stock markets. Using a generalised vector autoregressive (VAR) model, we introduce a new measure of liquidity spillovers. We find strong evidence of interconnection across countries. We also test the existence of liquidity contagion using a dynamic version of our static spillover index. Our results indicate that the transmission of shocks increases during periods of higher financial turbulence. Moreover, we find that core economies tend to be dominant transmitters of shocks, rather than absorber. The second essay investigates the role played by market liquidity in the execution of open-market share repurchases in the UK which is the most active market within the EU for this payout method. Using a unique hand collected data set from Bloomberg Professionals, we find that the execution of share repurchases does not depend on the long-term underlying motive, but it rather relies on market liquidity and other macroeconomic variables. We also provide a methodological contribution using censored quantile regression (CQR), which overcomes most of the econometric limitations of the Tobit models, widely employed previously within this literature. The third essay quantifies the welfare gains from trade for the Eurozone countries. We apply a trade model that allows us to estimate the increase in real consumption as a result of trade between countries. We estimate welfare gains using two sufficient aggregate statistics. These are the share of expenditure on domestic goods and the elasticity of exports with respect to trade cost. We offer a methodological contribution for the estimation of elasticities by applying the Poisson pseudo-maximum likelihood (PPML) using a gravity model. PPML allows the estimation of gravity models in their exponential form, allowing the inclusion of zero trade flows and controlling for heteroskedasticity. Previous studies present several econometric limitations as a result of estimating gravity models in their log-linearised form. Our results indicate that joining the euro did not significantly increase trade gains for member countries. Nevertheless, differences across countries are significant and Northern economies experience a higher increase in welfare gains trade as compared to Southern economies.

Local governments are often willing to offer companies generous tax incentives to attract businesses to their region. In the United States, many states have tried to attract film productions and establish local film industries by offering different forms of state film tax incentives. As a prominent example of this, the state of Georgia offers a film tax credit which has no annual maximum compensation cap, creating an attractive tax environment for large film productions. The purpose of this study is to investigate if the Georgia state “Film, Television and Digital Entertainment Tax Credit” significantly affected film jobs in the state, and if any other industries were also affected through cross-industry employment spillovers. A difference in differences approach was used by way of the synthetic control case study method. This method estimates the counterfactual development of the outcome variable by creating a synthetic Georgia consisting of a weighted combination of untreated states. The results show a large and highly significant effect of the tax credit on film production jobs. However, little evidence of employment spillovers from the film industry is found, with only a select few affected industries being insurance and interior design. These results imply that tax incentives can establish a local film industry, but likely only if the annual maximum compensation is high or uncapped, making for a significantly more generous incentive than the average.

No / The existing literature treats advanced technology sourcing as the only cause of reverse productivity spillovers from local to foreign firms and implies that mutual spillovers between foreign and local firms can only happen in the developed world. This paper argues that the diffusion of indigenous technology and local knowledge helps the productivity enhancement of multinationals, so that there can be mutual spillovers even in a developing country. The results from a large-sample firm-level econometric analysis and a comparative case study of seven companies in Chinese manufacturing support this new argument, as mutual spillovers are identified between local Chinese firms and overseas Chinese or OECD-invested firms.

Yes / This paper examines the existence of dynamic spillover effects across petroleum based commodities and among spot-futures volatilities, trading volume and open interest. Realized volatilities of spot-futures markets are used as inputs to estimate a VAR model following Diebold and Yilmaz (2014, 2015) and distinguish dynamic spillovers in total and net effects. Results reveal the existence of large and time-varying spillovers among the spot-futures volatilities and across petroleum-based commodities when examined pairwise. In addition, speculative pressures, as reflected by futures trading volume, and hedging pressures, as reflected by open interest, are shown to transmit large and persistent spillovers to the spot and futures volatilities of crude oil and heating oil-gasoline markets, respectively.
