abstract: In this study I investigate the organizational strategies that Chinese power generation companies may use to reduce the impact of coal price increases on their profits. Organizations are open systems in that no organization possesses all the resources that it needs and all organizations must obtain resources from their external environments in order to survive. Resource dependent theory suggests that the most important goal of an organization is to find effective mechanisms to cope with its dependence on the external environments for resources that are critical to its survival. Chinese power generation companies traditionally rely heavily on coal as their raw materials, and an increase in coal price can have a significant negative impact on their profits. To address this issue, I first provide a systematic review of the resource dependence theory and research, with a focus on the strategies such as vertical integration, diversification, and hedging that organizations can undertake to reduce their dependence on the external environment as well as their respective benefits and costs. Next, I conduct a qualitative case analysis of the primary strategies the largest Chinese power generation companies have used to reduce their dependence on coal. I then explore a new approach that Chinese power generation companies may use to cope with increases in coal price, namely, by investing in an index of coal companies in the stock market. My regression analysis shows that coal price has a strong positive relation with the price of the coal company index. This finding suggests that it is possible for firms to reduce the negative impact of raw material price increase on their profits by investing in a stock market index of the companies that supply the raw materials that they depend on. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2015

Given the extensive participation of mining stocks in the Peruvian stock market, the Lima Stock Exchange (BVL) provides an ideal setting for exploring both the impact of metal returns on mining stock returns and stock market volatility, and the comovements between mining stock returns and metal returns. This research is a first attempt to explore these issues using international metal prices and the prices of the most important mining stocks on the BVL and the IGBVL index. To achieve this, we use univariate GARCH models to model individual volatilities, and the Exponentially Weighted Moving Average (EWMA) method and multivariate GARCH models with time-varying correlations to model comovements in returns. We found that Peruvian mining stock volatilities mimic the behavior of metal volatilities and that there are important correlation levels between metals and mining stock returns. In addition, we found time-varying correlations with distinctive behavior in different periods, with rises potentially related to international and local historical events. / Dada la amplia participación de acciones mineras en el mercado de valores peruano, la Bolsa de Valores de Lima (BVL) resulta un escenario ideal para explorar tanto el impacto de los ren- dimientos de acciones de metales en los rendimientos de las acciones mineras y la volatilidad del Mercado de valores, así como los co-movimientos entre los rendimientos de las acciones mineras y los rendimientos de los metales. Este estudio es un primer intento en explorar estos temas usando precios internacionales de los metales y los precios de las acciones mineras más importantes de la BVL y del índice IGBVL. Para conseguir esto, hemos usado modelos GARCHunivariados para modelar las volatilidades individuales, y el método de Media Móvil Ponderada Exponencialmente (EWMA) y modelos GARCH multivariados con correlaciones de variantes en el tiempo a modelos de co-movimientos en rendimientos. Hemos encontrado que las volatilidades imitan el comportamiento de las volatilidades de los metales y que hay importantes niveles de correlación entre los metales y el retorno de las acciones mineras. Adicionalmente, encontramos correlaciones variantes en el tiempo con un comportamiento distintivo en periodos diferentes, el que aumenta potencialmente en relación con eventos históricos internacionales o nacionales.

Exchange rate risk, interest rate risk and oil price fluctuations are the most demonstrated risks in the GCC (Gulf Cooperation Council) countries (Arouri and Nguyen, 2010). Research, however, in this area is still underdeveloped. The importance of this study is to contribute to this research gap. This research aims to show how these three risks affect firms' market values by examining 473 listed firms in Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and United Arab Emirates for the period January 2007 to June 2012. The research further examines the determinants of these risks. The study uses the AR (1) EGARCH-M model. The results indicate that stock returns in GCC countries are influenced by the exchange rate risk, interest rate risk and oil price risk. However, the exposure was highest for exchange rate risk and lowest for interest rate risk. While the effects of these risks were mixed, overall, exchange rate risk and oil price risk showed more positive significance as compared to the interest rate risk that showed more negatively significant effect on firm values. The level of the effect of these risk also differed from country to country. However, firms in United Arab Emirates revealed the highest exposure to all the three risks while those in Saudi Arabia showed the least exposed to the three risks. Oman firms also showed high exposure to exchange rate and interest rate risks. The segregated results overall showed lower exposure of financial firms as compared to non-financial firms. However, the non-financial firms in Bahrain were more exposed to the risks than the financial firms. In Saudi Arabia, the financial firms revealed the least exposure to the risk suggesting effective risk management practices. In addition, foreign operations and firm size had a significant influence on the extent of the firms’ exposure to all the three risks. Leverage also influenced the level of exposure to interest rate risk. Profitability, growth and liquidity did not reveal a significant influence on the level of exposure. Further, increasing the risk does not lead to increased returns in most of the GCC countries. The risk-return parameters were largely negative. However, positive news increases return volatility more than negative news in most countries. Also, the current volatility of most GCC firms’ returns are time varying, are a function or past innovation and past volatility. The volatility of stock returns, which is affected by changes in the risk factors, could demonstrate the non-prioritisation of risk management by firms.

Thesis brings broader picture about the relationship between unconventional measures implemented by ECB and valuation of banking sector in the Eurozone. It also examines implementation of unconventional measures with regard to the three crises, which struggled European economy in the years thereafter the beginning of the last financial crises. Attention is also directed towards factors which have direct impact on the valuation of banks and are influenced by steps adopted by monetary authority. For this purpose two stage dividend discount model, model of economic value added, and price to book ratio model are used. Main tools necessary for the analysis are databases of the platform Bloomberg and statistics gathered by ECB. Hypothesis suggesting the positive relationship between unconventional measures implemented by ECB and valuation of banking sector in the Eurozone is proved for mid-term horizon. In case of immediate reaction of shares the results are divided based on the structure of specific measure and also on the expectations of financial market. Thesis as a whole confirms the positive effects of unconventional measures on the valuation of shares, therefore entice to additional research. In fact sometimes monetary policy might cause distortion in the prices on the financial markets and endanger main goals of central bank.

abstract: Recent research finds that there is significant variation in stock market participation by state and suggests that there might be state-specific factors that determine household stock market participation in the United States. Using household survey data, I examine how accounting quality of public companies at the state level affects households’ stock market participation decisions. I find that households residing in states where local public companies have better accounting quality are more likely to invest in stocks. Moreover, those households invest greater amounts of their wealth in the stock market. Cross-sectional tests find that the effect of accounting quality on stock market participation is more pronounced for less affluent and less educated households, consistent with prior findings that lacking familiarity with and trust in the stock market is an important factor deterring those types of households from stock investments. In state-level tests, I find that these household outcomes affect income inequality, which is less severe in states where high public-firm accounting quality spurs more stock market participation by poorer households. Conversely, in states where public firms have lower accounting quality, stock market participation among poorer households is less common, and a larger share of high equity returns accrues to richer households, exacerbating income inequality. / Dissertation/Thesis / Doctoral Dissertation Accountancy 2020

This research aims to examine if a negative relationship exists between the dividend yield and stock price volatility of firms listed on the Swedish Stock exchange market, which is of utter interest and intrinsic for investors and financial analyst in the process of valuing a security’s and a stock portfolio's risk and return. The data that was utilized for this study consists of 52 companies for the period of 2010 to 2019 which makes up for 520 observations. A pooled regression model and a multiple ordinary least squares model was applied to test the relationship. The results show a negative relationship between the dividend yield and stock price volatility. On the other hand, the results indicate that there is a significant positive relationship between earnings volatility and stock price volatility. However, there is a negative relationship for leverage, market value and asset growth with stock price volatility.

The objective of this study is to investigate the impact of a few selected macroeconomic variables on the Swedish stock market index OMXS30. The study uses time series monthly data during the period 2000-2019. To investigate these relationships, the time series are transformed into stationary processes. Then, we construct a Vector autoregressive model (VAR) and conduct Granger causality tests. The results indicated a negative relationship between inflation and the return on stocks, interest rate and the return on stocks, as well as positive relationship between money supply and the return on stocks. The VAR-model and the Granger causality test failed to show any statistically significant relationship between exchange rate and stock prices. The same Granger Causality tests suggests a bidirectional relationship between interest rate and the return of OMXS30, as well as unidirectional relationship between inflation and the stock prices, where inflation Granger causes the return of OMXS30.

This analyses the impact of unexpected changes in monetary policy on the South African equity market over the period 2005 -2018. In an attempt to understand this relationship, two main views have emerged. The wealth effect suggests that monetary policy changes have an indirect effect on the stock market, via changes in the value of private portfolios. On the other hand, it has been argued that the stock market is an independent source of macroeconomic volatility to which policy makers may wish to consider. This paper applies an event study approach to examine the stock market reaction to monetary policy. Furthermore, to understand the economic sources underpinning that reaction a Vector autoregressive model is estimated. The results suggest that on average, a surprise rate hike of 100 basis points causes short term JSE All Share index total returns to decline by 2.71%. We also find that the stock market reacts positively (negatively) to expansionary (contractionary) unexpected monetary policy actions due to revised market expectations about future dividends, excess premiums and the discount rate. The findings are crucial for central bank policy makers and JSE stock market investors.

El presente proyecto es sobre la investigación y acompañamiento para que las medianas empresas en el Perú busquen financiamiento a través del Mercado Alternativo de Valores, nos muestra su viabilidad en base a las tasas y montos que le otorgan otros agentes financieros que existen en el mercado, que permitió detectar una oportunidad de negocio ya que existe mucha oferta, pero muy poco conocimiento de estos otros medios de financiamiento por parte de los clientes, lo que genera frustración en las empresas, y disminuye sus oportunidades de crecer, así como de impulsar nuestra economía y el sector formal de la misma. Para su puesta en marcha requerirá de un capital inicial de S/31,150.00, financiado en un 100% por los accionistas de la empresa, esperando recuperarlo el tercer año de operación. / The present project is about the investigation and accompaniment so that medium-sized companies in Peru seek financing through the Alternative Securities Market, it shows us its viability based on the rates and amounts that other financial agents that exist in the market, that allowed us to detect a business opportunity since there is a lot of supply, but very little knowledge of these other means of financing by customers, which generates frustration in companies, and decreases their opportunities to grow, as well as boost our economy and the formal sector of it. For its start-up, it will require an initial capital of S / 31,150.00, financed 100% by the company's shareholders, hoping to recover it in the third year of operation. / Trabajo de investigación
