In this study, we examine how advertising and customer satisfaction affect a firm¡¦s systematic risk (£]-risk) under both the highly volatile and tranquil market. This study extends prior studies that primarily considered the effects of marketing initiatives on performance metrics, focusing on systematic risk under the highly volatile and tranquil market. We examine how advertising and customer satisfaction affect a firm¡¦s £]-risk under the two distinct markets. We develop a two-stage model procedure. First, each individual firm¡¦s £]-risk in the both markets is estimated by Fama-French-Carhart-Ang 5-factor model which includes implied volatility index (VIX) as an aggregate volatility factor, along with the estimators of maximum likelihood (MLE) under the Markov switching model. Second, to examine the impact of advertising and customer satisfaction on £]-risk, we estimate empirical models for the dataset of the two distinct markets by the generalized method of moments (GMM) and the quantile regression. The results significantly support our hypotheses that higher advertising and higher customer satisfaction lower a firm¡¦s £]-risk under the overall, highly volatile and tranquil markets from the standpoint of long run. Furthermore, we find an additional discovering that from the view of short term, adverting is negatively significant associated with £]-risk under the highly volatile market, while customer satisfaction is not. Customer satisfaction, however, is negatively significant associated with £]-risk under the tranquil market, while advertising is not.

In retrospect, telecommunication technology and services have seen incessant renovation and development. The wave of liberalization is also the inexorable trend in the global telecommunications industry, the telecommunications industry in Taiwan can not be excluded itself from the trend. The telecommunications industry in Taiwan has been opened by degrees and sought to establish a fair competitive environment. In the meantime, there are several important changes no matter in facets of regulatory regimes, industrial structure, technology, or market demand, etc. The environment of telecommunications industry became more volatile than the monopoly one's. We extend the opinion of Noam (2006) who observed the long-term upturn and downturn in the American telecommunications industry and concluded that that volatility and cyclicality will be an inherent part of the telecommunication sector in the future. First, in our thesis we explore the cyclical behavior of Taiwan telecommunications industry. As the turning point of the telecommunications industry may be obscure, we adopt a Markov Regime-Switching model with two regimes representing contraction and expansion. This nonlinear, two states, regime-switching model shows that Taiwan telecommunications industry has suffered from the cyclic fluctuation since the liberalization had been followed out. We focus on the mobile phone industry thereafter in this study. Since three telecommunication-related laws passed in 1996, the mobile phone industry is the first industry implemented the liberalization policy. In the process of the mobile phone industry's evolution, the carriers in this industry all experience the rapid growth in the mobile phone penetration rate and the fierce competition. Hence, to identify the main explanatory factors of the mobile phone industry fluctuation and cycles we introduce an 11-variable vector autoregressive (VAR) model. The empirical results confirm that the mobile phone industry' output can be influenced by five factors mainly including the macroeconomic status, demand, network effect, relative equipment import price, and output price, and furthermore, the impetus of the liberalization policy and the progress of the technology also play an important role beyond the five main factors in terms of the separate carriers' analysis.

In this thesis, the regime dependent mean and abnormal returns are studied to examine whether socially responsible mutual funds have a different performance from traditional mutual funds, since there may be different patterns in the economy. Five economic factors - stock returns, treasury yield spread, credit spread, economic confidence and building permits - are used to identify the market regimes, which are determined as bear and bull markets. The regime-dependent abnormal returns are calculated with a regime-switching Fama & French three factor asset-pricing model. The empirical results show that socially responsible mutual funds have statistically higher mean return than non-socially responsible mutual funds in both bear and bull markets. However, using the measurement of the abnormal returns, socially responsible mutual funds statistically underperform non-socially responsible mutual funds in bull market, while the performance of the two types of funds are not statistically differentiable in the bear market.

This thesis addresses asset pricing in Chinese A-share stock markets using a dataset consisting of all shares listed in Shanghai and Shenzhen stock exchanges from January 1997 to December 2007. The empirical work is carried out based on two theoretical foundations: the efficient market hypothesis and behavioural finance. It examines and compares the validity of two traditional asset pricing models and two behavioural asset pricing models. The investigation is initially performed within a traditional asset pricing framework. The three-factor Fama-French model is estimated and then augmented by additional macroeconomic and bond market variables. The results suggest that these traditional asset pricing models fail to explain fully the time-variation of stock returns in Chinese stock markets, leaving non-normally distributed and heteroskedastic residuals, calling for further explanatory variables and suggesting the existence of a structure break. Indeed, the macroeconomic and bond market factors provide little help to the asset pricing model. Using the Fama-French model as the benchmark, further research is done by investigating investor sentiment as the third dimension beside returns and risks. Investor sentiment helps explain the mis-pricing component of returns in the Fama-French model and the time-variation in the factors themselves. Incorporating investor sentiment into the asset pricing model improves the model performance, lessening the importance of the Fama-French factors, and suggesting that in China, sentiment affects both the way in which investors judge risks as well as portfolio returns directly. The sentiment effect on asset pricing is also examined under a nonlinear Markov-switching framework. The stochastic regime-dependent model reveals that stock returns in China are driven by fundamental factors in bear and low volatility markets but are prone to sentiment and become uncoupled from fundamental risks in bull and high volatility markets.

This research consists of two essays. The first essay entitled” Stock Return Forecasting with Sum-of-the-Parts Methodology: Evidence from Around the World”, examines forecasting ability of stock returns by employing the sum-of-the-parts (SOP) modeling technique introduced by Ferreira and Santa-Clara (2011).This approach decomposes return into three components of growth in price-earnings ratio, earnings growth, and dividend-price ratio. Each component is forecasted separately and fitted values are used in forecast model to predict stock return. We conduct a series of one-step ahead recursive forecasts for a wide range of developed and emerging markets over the period February 1995 through November 2014. Decomposed return components are forecasted separately using a list of financial variables and the fitted values from the best estimators are used according to out-of-sample performance. Our findings show that the SOP method with financial variables outperforms the historical sample mean for the majority of countries. Second essay entitled,” Equity Premium Predictability under Regime Shifts: International Evidence”, utilizes the modified version of the dividend-price ratio that alleviates some econometric concerns in the literature regarding the non-stationary and persistent predictor when forecasting international equity premium across different regimes. We employ Markov switching technique to address the issue of non-linearity between the equity premium and the predictor. The results show different patterns of equity premium predictability over the regimes across countries by the modified ratio as predictor. In addition, transition probability analysis show the adverse effect of financial crisis on regime transition probabilities by increasing the probability of switching between regimes post-crisis 2007 implying higher risk perceived by investors as a result of uncertainty inherent in regime transitions.

In order to catch up the international trend, ¡§Expensing employee bonus¡¨ has been implemented in Taiwan since year 2008. Hence, all the cost concerning employees¡¦ bonuses have been recorded as expense in the income statement and recognized by fair market value. Since the company decides total amount of employees¡¦ bonuses after authorized by the board and annual general meeting, it can distribute the proportion of cash and stock bonuses. As the result of calculating the stock bonus by stock¡¦s fair value, employees gain much less stocks than before, which lessen the encouragement effect. Therefore, enterprises begin to increase the standard salary of employee or proportion of cash bonus. This study collects the data from the fourth quarter of year 1989 to the third quarter of 2009, and chooses the Taiwan Weighted Stock Index and the stock prices of listed electronic firms in Taiwan. Using the Markov Regime Switching Model as the research method, and add the macroeconomic and financial variables to separate the stock price into two regimes- recession and expansion regime. This research is in the employee¡¦s shoes, and to study what stock incentives strategies the company should adopt under the required expensing of employee stock bonus. The empirical results are summarized as follows: 1.Under the expansion regime, if the company¡¦s stock price was affected by both macroeconomic and financial variables, it will more likely rise further, which leads to the large gap between two regimes. For example: Cyberlink, Acer and Mediatec, which stock price gaps are over ten dollars. 2.According to the two arguments of this study: the company with long duration of expansion regime and is influenced by macroeconomic and financial variables should adopt the strategies based on stock bonus. Therefore, according to the empirical results, the study suggests that Acer is the suitable company to do the strategies.

In order to get maximum profit, investors start to high attention on risk management after financial crisis in 2008. Therefore, risk management and predict become more and more complex. This paper mainly focuses on two risks, including non-systematic risk and credit risk. After financial crisis, countries pay more attention on credit risk, and now because of Europe debt crisis, investors and governments are also concerned with the messages about credit rating which are published by Credit Rating Agency. Besides credit risk, the firm¡¦s specific risk (i.e. non-systematic risk) is also more important than before. Recent empirical studies find that the stock is not on affected by systematic risk, but also affected by non-systematic risk. According to Kuo and Lu (2005), this thesis uses two models: Moody¡¦s KMV credit model and Markov regime switching model to estimate credit risk and non-systematic risk. The period is from January 2002 to November 2010. Testing samples are data from constituent stocks of the Taiwan 50. The purpose of this paper is researching the relationship between credit risk and non-systematic risk. The empirical results show that there is the positive relationship between non-systematic risk and credit risk. And among different industries, non-systematic risk or credit risk also shows the significant differences. For plastic industry and communications network industry, there is lower credit risk. However, for electronics industry and financial industry, there is higher credit risk. The study also found that even in the same industry, each company will face different risk level.

Since reformed of banking structure in China, banks have been gradually developed their operation system. Moreover, the restructure in commercial bank after joined WTO had established China¡¦s banks performance and international reputation. Since 2007, many large commercial banks have strength its risk management based on the commitments made by China Banking Regulatory Commission (CBRC) to follow the New Basel Capital Accord. When the global banking industry is devastated by global financial crisis (GFC) during 2008, China¡¦s banks are less affected by GFC. In addition, the capital scale and revenues performance were thrived during GFC. Therefore, it shows that banks in China had improved the resilience ability during financial crisis. However, being originated in China¡¦s loose monetary policy and economic stimulus package after GFC, investors worried that domestic banks might bear high risks. Notably, the risk is specific risk from each bank instead of system risk. This study employs Markov regime-switching model to examine 14 China banks¡¦ stock prices. The empirical evidence supports our hypothesis that behavior of China banks¡¦ stock prices has confronted structural change after GFC. Furthermore, this research presents that unsystematic risks from each bank were significantly decreased after GFC. It indicates that investors are too pessimistic on the banks in China might suffer high risk after government interventions.

This study tires to find out how a firm¡¦s advertising and customer satisfaction influence firms¡¦ abnormal return and we uses the abnormal return (i.e. Jensne¡¦s £\) as the proxy of firm¡¦s shareholder value. We expect firms¡¦ advertising and customer satisfaction will have a positive impact on abnormal return while having a negative impact on firms¡¦ risk. In addition, we also consider under different market state whether advertising and customer satisfaction have an asymmetric effect. Compare with Carhart (1997) four factor model, this paper also takes the factor of VIX into account, and we use Markov regime switching model to recognize bull market and bear market because it can help us get a more accurate estimation. We choose the Generalized method of moments (GMM) to estimate the impact of advertising and customer satisfaction on shareholder value and discuss that whether advertising and customer satisfaction are able to lift up shareholder value or not. The outcome shows that advertising doesn¡¦t have significantly positive impact on firms¡¦ abnormal return under bull market and bear market. However, customer satisfaction has a significantly positive relationship with firms¡¦ abnormal return under bull market and bear market. And we find that if firms maintain the level of customer satisfaction under bear market, it will be more efficiently to lift up firms¡¦ abnormal return rather than spending more money on advertising.
