The thesis examines the dynamic impact of capital structure on firm performance in Nigeria. The aims of this thesis are; first, to investigate the impact of capital structure of firms on their performance in a dynamic framework. This is unlike previous studies in the capital structure literature that have used static analysis. Second, to examine the dynamic feedback from performance to capital structure using the two-step system generalized method of moment estimator. Third, to explore the determinants or variables that influence capital structure choice of firms in Nigeria and the rate of adjustment to achieve optimal debt position. Fourth, to assess the possibility of non-monotonicity effect of capital structure on firm performance and non-monotonicity effect of performance on capital structure. The second chapter discusses the theoretical framework and review the empirical literatures on capital structure and firm performance. Also, the chapter review empirical literature on firm performance and capital structure as well as on determinants of capital structure. The study find much evidence in support of the theoretical prediction of the agency cost theory of capital structure. The stuudy observed that there are limited empirical studies on the franchise value and efficiency-risk hypotheses of reverse causality from performance to capital structure. The empirical literatures on determinants of capital structure suggests that both firm specific and country factors are important variables that drive capital structure choice of firms. The thrid chapter examines the methodology of the study. The population, sampling and sampling size, estimation methods were discussed in this chapter. The fourth chapter analysis and described the data employed in the study. Specifically, the results of the dynamic relationship between capital structure and firm performance were presented in this chapter. The results indicate that capital structure has non-monotonic effect on firm performance thereby supports the agency cost theory of capital structure. The fifth chapter provides results on the reverse causality between performance and capital structure. The findings indicate that there is reverse causality between performance and capital structure. This is evidence in the statistically significant negative finding between performance and capital structure. This finding support the franchise value hypothesis. The findings of this study also reveal that non-monotonic relationship exist between performance and capital structure. The sixth chapter provides results on the determinants of capital structure of Nigerian firms. The findings indicate that both firm specific variables (return on equity, risk, profitablity, age, size, tangibility, growth opportunities, dividend, ownership) and country variables (inflation, interest rates, credit to private sector as percentage of gross domestic product, institutional quality) jointly influence capital structure choice of firms in Nigeria. The findings equally indicate that firms in Nigeria adjust to their optimal debt target relatively faster with lower cost of adjustment because of better access to private debt that public debt. Conclusions from the empirical chapters indicate that firm specific and country factors are major determinants of capital structure of firms in Nigeria and that capital structure choice of firms influence their performance. Equally, there is evidence that indicate that there is reverse causality from performance to capital structure of firms. The study therefore contend that the agency cost theory of capital structure and franchise value hypothesis are portable in the Nigerian context. Full portability of these theories in emerging market like Nigeria may require modifications to accommodate specific peculiarities of operating and business environment of Nigeria.

The diploma thesis deals with the evaluation of the effectiveness and risks of a private construction project. This work is divided into two parts. The first part is a theoretical part, which defines the basic concepts associated with investment as such, but also directly with investment in real estate and construction investment. In the second part, this work deals with risk assessment, determination of their size and finally risk management. The end of the theoretical part is the elaboration of methodology for the practical part. The beginning of the practical part the work is devoted to the description of the construction area and specification of the building itself. In the next part are set investment costs, operating income and expenses. Operating income consists of the lease itself. This was determined on the basis of similar investments in the area. Operating expenses are divided into fixed and variable where only fixed are included in the evaluation. Subsequently, the work establishes the profit and loss statement and therefrom the cash flows. The second part defines the risks associated with the construction of the project. The switching value is then calculated for critical project risks. The end of the practical part is devoted to risk management. The conclusion summarizes the results of individual parts of the thesis and a written recommendation for the investor whether to realize the project or not.

The introduction of PPPs in infrastructure provision has changed the way in which governments around the world now view infrastructure provision. However, the introduction of PPPs to deliver the needed infrastructure has benefited only a few companies. Most of these companies are the big construction firms that possess technological know-how and those that have the financial ability to execute large infrastructure projects. Although SMEs are important for employment creation, inequality and poverty reduction, the participation of SMEs in these PPP projects is very low. This is because PPP models in developing countries are based on those used in developed economies, and such models ignore the socio-economic problems facing developing countries. Therefore, this study argues that PPP projects in developing countries present an opportunity for growing the SME sectors in developing countries. It challenges the viewpoint of seeing infrastructure backlogs only as providing opportunities to big private sector companies and argues that infrastructure backlogs can be used by governments to reduce the triple challenges of unemployment, poverty and inequality by linking SMEs to PPP projects. The traditional PPP model that is being applied by many developing countries does not fully encourage the participation of SMEs in PPP projects, as most of the projects executed through this model are bundled into big projects that SMEs cannot execute due to a lack of technological know-how and weak balance sheets. The study therefore suggests different ways in which the participation of SMEs in PPP projects could be improved based on the results of the survey conducted for this study. The study then proposes an “innovative conceptual PPP model for sustainable SME development” that takes into account the needs for developing countries to create jobs, reduce poverty and inequality. It also takes into account all challenges for SMEs identified through the review of literature and the study survey. / Economics / D. Litt. et Phil. (Economics)
