This paper discusses capital structure theories, with special attention to partial-adjustment model. Strategic waiting theory of IPO firms and its relation to market timing theory are also discussed. Two empirical tests related to capital structure theory are included. First one is a test on the relation between a firm’s strategic waiting behavior in IPO market and its stock return. Second one is on the relation of a firm’s strategic waiting behavior in IPO market and its subsequent capital structure decision.

Bolagsskattesänkningen genomfördes den 1 januari 2013, målet med sänkningen var att stimulera Sveriges tillväxt då en sänk bolagsskatt sägs öka investeringsviljan. Med sänkningen ville man också minska incitamenten för företag att flytta sina verksamheter till lågskatteländer. Att bolagsskattesatsen sänktes väckte ett intresse som skapade denna uppsats att undersöka vilka faktorer det är som styr bolagsskattesatsen, till exempel, i en liten öppen ekonomi som den svenska.  Teorin grundar sig i kapitalstruktur och finansieringsbeslut. Faktorer som anses påverka bolagsskatten och som valts ut är utländska direktinvesteringar, öppenhet mot kapitalflöde och BNP per Capita. Datainsamling har skett sekundärt och bearbetats i det analytiska programmet R. Med hjälp av R och statistiska metoder har det genomförts paneldataanalys och regressionsanalys. Svaret är kort och gott, ja, faktorerna påverkar bolagsskattesatsen. Det visar att ett land som är större geografiskt och har en hög öppenhet för kapitalrörelser tenderar att ha en lägre bolagsskattesats och att det tycktes vara ett bra val av Sverige att justera bolagsskatten. / The goal with lowering of the Swedish corporate tax rate the 1st of January 2013 was to stimulate the Swedish growth, as a lower corporate tax rate is said to increase the will to invest. The incentives for corporations to move to low tax countries was also thought to be decreased due to the reduction.  When the tax rate was reduced an interest arise to examine which factors influence the tax rate, as for example, for a small economy as the Swedish. Theory presented is based on capital structure and finance decisions. The variables chosen is FDI, Openness towards capital flow and BNP per capita. Collection of data is secondary and has been analysed in the statistic program R with focus on panel data and regression analysis. The answer is for short, yes, the variables do indeed influence the corporate tax rate. Countries whom are larger geographically and has a high openness towards capital movement are more likely to have a lower corporate tax rate and it seemed to be a good choice of the Swedish parliament to lower the corporate tax rate.

This thesis examines the patterns and determinants of corporate financial policy (capital structure and dividend policy) in Zimbabwe. In particular it investigates various aspects of corporate financial behaviour in an emerging market; the evolution of corporate financial structure and dividend payout ratio over the past 25 years (1975-1999), the impact of the reform programme (introduced in 1992) on firm characteristics, the corporate financing patterns during the period 1990-1999, the determinants of corporate capital structures and dividend policy and the interaction between corporate financing and dividend policy decisions. The main results that emerge from the analysis suggest that (i) the debt ratio for the Zimbabwean corporate sector significantly increased after the reform (ii) the Zimbabwean corporate sector mainly depends on external finance (75 % of total financing) especially short-term finance, which contributes 52 % of total financing. Furthermore, the results support the following hypotheses (i) the pecking order hypothesis that firms prefer internal financing to external financing, (ii) the trade-off hypothesis that non-debt tax shields reduce the expected gains from leverage, (iii) firms use liquid assets to finance investments, (iv) the agency cost hypothesis that increasing managerial ownership helps to align the interests of managers and shareholders and therefore reduces the role of debt as an agency-conflict mitigating factor, (v) large firms have lower bankruptcy costs and therefore can support more debt than smaller firms, (vi) debt service limits the amount of cash paid out as dividends, and (vii) high growth firms rely on external finance more than low growth firms (viii) high growth and firms have low payout ratios (iv) Cash flows and institutional investors increase the likelihood that firms will pay dividends (v) capital structure and dividend policy decisions are interdependent and highly leveraged firms have low payout ratios.

In this thesis we study problems in the context of inventory control and facility location. In chapter 2 we study the competition among risk averse newsvendors. We showed that the well-known result for the single-product monopoly firm, which states higher risk aversion causes the firm to reduce its order quantity, cease to hold under the competition. We concluded that the higher risk aversion does not necessarily cause both firms to reduce their order quantity. We showed that the impact of risk aversion on equilibrium quantities is a trade-off between two effects: (a) Own risk aversion increment which causes that the firm reduces its order quantity and (b) Effect of spillover demand from competitor which causes that the firm increases its order quantity. We also show which firm raises its order quantity as both firms become more risk averse depending on their attributes: profitability ratio (overstocking to understocking ratio), initial risk aversion level and demand characteristic (distribution and substitution). In Chapter 3, we study how the operational decisions of a firm's manager depend on her own incentives, the capital structure, and financial decisions in the context of the newsvendor framework. We showed that in contrast to common practices, tying the manager's compensation to stock price (equity value) may not be optimal for shareholders. We propose to tie the managers' compensation to the firm value or include a debt-like instrument in the compensation package to mitigate the risk taking behaviour of the managers. We also show how the board of directors can modify the compensation structure based on the state of the economy and publicly available information about company's demand. In Chapter 4, we study the effect of risk attitude of decision makers on well-known location problems with uncertain demand. In addition to providing mathematical formulations for those problems, we also discussed how we can solve these problems using linearization techniques. We also shed some light on the importance of considering the volatility and correlation structure. Furthermore, we apply a Bayesian updating method, a useful tool for updating the probability distribution to incorporate the consultants' view about uncertain factors in location problems.

This thesis presents three essays on credit ratings of regulated utilities, dividend signaling, and asymmetric information and security issuances and repurchases. Chapter 2 investigates the practices of credit rating agencies by using the regulated utility industry as a natural testing ground. Following deregulation and the Enron scandal, the general opinion among industry professionals is that utilities are being punished by rating agencies. Contrary to this popular belief, we find that the utility credit ratings are significantly higher compared to those of other firms, and this significance is more pronounced in the post-deregulation period. Although rating agencies often cite regulatory reasons for placing utilities on negative credit watches, these firms ratings are rarely downgraded after being placed on negative watches. Chapter 3 provides a rational explanation for the disappearing dividend trend. Dividends serve as signaling device and, under models of dividend signaling under information asymmetry, cost of signaling increases with volatility of firms cash flows. Declining propensities to pay dividends imply that (1) information asymmetries have become lower and/or (2) cost of signaling has increased. We find evidence consistent with both. In particular, firms with higher information asymmetries and lower stock price informativeness are more likely to pay dividends: the increasing stock price informativeness has made dividend signaling less valuable, and a significant portion of disappearing dividend trend could be explained by rising risk and increasing stock price informativeness. Chapter 4 investigates the motivations for debt and equity issuances and repurchases in hot and cold markets. I find that firms issue equity in hot markets to reduce adverse selection costs associated with asymmetric information. In particular, firms issuing equity in hot markets possess high asymmetric information while firms issuing equity in cold markets possess less severe asymmetric information. I also find that credit ratings and market-to-book ratios could explain why firms might repurchase equity or issue debt in hot markets rather than issue equity: firms with high credit ratings and low market-to-book ratios are more likely to issue debt even in hot equity markets, and firms with low market-to-book ratios are more likely to repurchase equity in any market. / Finance

Investors buy those stocks with lower price. This paper investigates NYSE and Nasdaq stocks’ quarterly data from Jan.1, 2001 to Dec. 31, 2009. We use general moment method (GMM) to estimate the equation. The empirical results suggest: (1) The stock discount rate is increasing over time compared to prior researches. The average discount rate is 5.6%. (2) The stock price prior to claim day, earnings retention rate, return on average assets, return on average equity, depreciation and issue amount have statistically significant influences.

This dissertation, which consists of three essays, studies three applications. Each of them emphasizes the microfoundations of economic models. The first essay proposes a nonparametric estimation of structural labor supply and exact welfare change under nonconvex piecewise-linear budget sets. Different from previous literature, my method focuses on a nonparametric specification of an indirect utility function. I find that working with the indirect utility function is very useful in simultaneously addressing the labor supply problems with individual heterogeneity, nonconvex budget sets, labor nonparticipation, and measurement errors in working hours that previous literature was unable to. Further, the estimated indirect utility function proves to be convenient and efficient in calculating exact welfare change and deadweight loss under general piecewise-linear budget sets. In the second essay, I solve the equity premium, risk-free rate, and capital structure puzzles by laying a more solid microfoundation for consumption-based asset pricing models. I argue that the above two asset pricing puzzles arise from the aggregation of hump-shaped life-cycle consumption into per capita consumption, which accounts for the unanimous rejections of Euler equations in the literature. As for the third puzzle, I show that a firm's capital structure can be determined by heterogenous investors maximizing life-time utility even though the capital structure is irrelevant on the firm side. The endogenously determined leverage generates an even larger equity premium than a fixed one. The third essay studies the solution concepts of coalition equilibrium. Traditional solution concepts such as Strong Nash Equilibrium, Coalition-proof Nash Equilibrium, Largest Consistent Set, and Coalition Equilibrium violate the fundamental principles of individual rationality. I define a new solution concept, Weak Coalition Equilibrium, which requires each coalitional deviation to be within-coalition self-enforceable and cross-coalition self-enforceable. The cross-coalition self-enforceability endows coalitions with farsightedness. Weak Coalition Equilibrium is a generalization of Coalition-proof Nash Equilibrium and a re nement of the concept Nash Equilibrium. It exists under a weak condition. Most importantly, it is in line with the principle of individual rationality.

Cette thèse examine l’impact de la structure actionnariale sur la structure du capital et la performance des banques commerciales européennes sur la période 2002-2010. Elle est composée de trois essais empiriques. Le premier chapitre teste l'effet de la divergence entre les droits de contrôle et les droits pécuniaires d'un actionnaire ultime sur l’ajustement du ratio du capital à son niveau optimal et sur l’offre de crédit par les banques. Les résultats montrent qu’en présence de divergence entre les droits de contrôle et les droits pécuniaires, les banques n’émettent pas du capital pour augmenter leur ratio et, au contraire, elles réduisent leur taille en ralentissant leur offre de prêts. Le chapitre 2 teste l’effet de cette divergence sur la rentabilité et le risque bancaires en temps normal et en temps de crise. Les résultats montrent que bien qu'une divergence entre les droits de contrôle et les droits pécuniaires soit associée en temps normal à une rentabilité plus faible et un risque plus élevé elle a, à contrario, amélioré la rentabilité et contribué à la résilience des banques pendant la crise financière de 2007-2008. Le troisième chapitre teste si le réseau des actionnaires auquel la banque est liée au sein d’une chaîne de contrôle affecte la relation entre la diversification et la performance. Les résultats montrent que la présence des investisseurs institutionnels dans les chaînes de contrôle aide les banques à tirer des bénéfices lorsqu’elles diversifient leurs activités. / This dissertation examines the role of ownership structure in explaining capital structure and performance of European commercial banks from 2002 to 2010. It comprises three empirical essays. The first chapter explores the effect of greater control rights than cash-flow rights of an ultimate owner on the bank’s capital ratio adjustment and its lending decisions. The results show that whenever control rights exceed cash-flow rights, banks do not issue equity to increase their capital ratio and, instead, downsize by mainly slowing their lending. Chapter 2 provides evidence on how the divergence between control and cash-flow rights affects bank profitability and risk during normal times and distress times. The findings emphasize that during normal times the divergence between control and cash-flow rights is associated with lower profitability and higher risk. Conversely, during the acute financial crisis period (2007-2008), such a divergence improves profitability and banks’ resilience to shocks. The third chapter takes into account differences in the strength of ownership network to which banks belong when assessing the effect of greater activity diversification on bank performance. The results show that diseconomies of diversification vanish the stronger is the ownership network surrounding the bank in the control chain. Such mitigating roles are attributable to the presence of domestic and foreign institutional owners in the pyramid.

Theme of this thesis is capital structure of the company and capital productivity. The aim is evaluation of relationship between capital structure of the company and capital productivity followed by recommended suggestions to optimize capital structure of the company from the perspective of increasing the capital productivity. The first part of this thesis clarifies theoretical knowledge from Czech and foreign literature. In the practical part, the analyzed company is presented and the analysis evaluating capital structure of the company are made. Afterwards capital produktivity and its relationship to capital structure is evaluated. Bases for practical part were gained from financial statements of selected company. In conclusion, there are presented recommendations to optimize the capital structure in terms of capital productivity for analyzed company.

Assess the capital structure of the company, including influencing factors. Further evaluate various concepts cost of capital, cost of analyzing individual components of equity in a particular company and assess their impact on business performance.
