However, behavioral patterns differ between developed and ASEAN countries. In developed nations, policy rate changes have inconclusive effects on loan growth, while profitable banks and inflation drive credit expansion. In ASEAN countries, policy rate increases are associated with loan growth, reflecting favorable economic conditions. Financial development impacts credit expansion …

Forecasting Stock Volatility With Neural Network On Time Varying Transition Probability, Wasit Norakarntiansin
Forecasting Stock Volatility With Neural Network On Time Varying Transition Probability, Wasit Norakarntiansin
Chulalongkorn University Theses and Dissertations (Chula ETD)
Forecasting volatilities of financial security returns are important for many financial applications e.g., portfolio investment construction, risk management and trading strategy. The GARCH model has long been refined to capture the true dynamic of volatility on a security return. By applying the Markov switching to the GARCH model, the source of the temporary high volatility and high persistence of a shock to the volatility can be captured. In this study, we refine the Markov switching GARCH model further by applying the notion of the neural network to approximate the time varying transition probabilities. We aim to achieve a model that …

The Impact Of Moral Hazard In Institutional Environment On The Decision To Perform Partial Acquisition Or Full Acquisition, Thornthep Paengsawat
The Impact Of Moral Hazard In Institutional Environment On The Decision To Perform Partial Acquisition Or Full Acquisition, Thornthep Paengsawat
Chulalongkorn University Theses and Dissertations (Chula ETD)
This paper investigates the impact of moral hazard on the corporate strategic decision regarding Mergers and Acquisitions. Whether the decision by the acquirer to make partial or full acquisitions is driven by moral hazard is the main implication of this research paper. Considering several subsamples of mergers and acquisition transactions, in domestic transaction, an increase in private benefits of control does increase the odd of making partial acquisition. Considering the subsample of cross-border acquisitions, private benefits of control still increases the odd of making partial acquisition but the effect is less pronounced. Having control for the profit-maximizing reasons to make …

Chulalongkorn University Theses and Dissertations (Chula ETD)
This research presents empirical studies on the impact of mergers of equals on shareholders’ wealth. Due to integration problems between combining corporations, Daimler-Chrysler merger failures caused the corporate sector to think that mergers of equals erode shareholder wealth. However, it is based on a small proportion of MOE transactions, and there is no empirical evidence on the shareholder’s return on the announcement date implications of MOEs related to the size of the merger. I provide this research knowledge for the shareholder wealth at the announcement date for the implications of MOEs related to the size effect of the merger. Furthermore, …

Are Short Sellers Equally Informed? Evidence From The Us. Credit Rating Announcements, Omtong Kasemsant
Chulalongkorn University Theses and Dissertations (Chula ETD)
This study uses credit rating and daily short sale data of firms listed in NYSE from January 2015 to December 2021 to examine whether there is informed trading. Although post-announcement abnormal return is negatively correlated with abnormal short volume, no evidence of informed short selling is found. Higher level of pre-announcement abnormal short selling is positively correlated to default risk and also explained by the incentives of short sellers to short more when past returns are negative. Furthermore, increase in short selling that is preceded by credit watch placement is more pronounced before credit rating downgrades. Moreover, the evidence shows …

Do Issuers Affect Derivative Warrants Overpricing? Evidence Of Thailand, Sarunporn Thupthong
Do Issuers Affect Derivative Warrants Overpricing? Evidence Of Thailand, Sarunporn Thupthong
Chulalongkorn University Theses and Dissertations (Chula ETD)
Derivative warrants have become increasingly popular in many countries. However, numerous literatures provide the empirical evidences that derivative warrants are overpriced relative to the comparable options. Many researchers found that the derivative warrant overpricing can be explained by hedging cost, liquidity premium, market power, and asymmetric information of investors. These explanations are likely to be related to characteristics of derivative warrant issuer. Therefore, this paper comes up with the objective to reconfirm the overpricing phenomenon in Thailand and investigate the issuer identity effect on the derivative warrant overpricing as well as examine what issuer’s characteristics cause the level of overpricing …

Furthermore, after dividing the index into 3 types, all types of policy also reduce …
