Differential Impact of Investor Sentiment on the Capital Asset Pricing Model and Discounted Cash Flows Model Estimates of the Rate of Return on Equity

Traditional asset pricing models such as Capital Asset Pricing Model (CAPM) and Discounted Cash Flow (DCF) have been used widely in academics and practice due to their simplicity and popularity. The CAPM is a prescriptive model that describes the relationship between a stock’s required return and risk relative to the movements in the market, while the DCF is a descriptive model that measures the realized rate of return on a stock based on the market price of the stock, which in turn incorporates investor perceptions about the stock and the market. In an ideal, efficient market where investors behave rationally, we should not see much of a difference between stock returns estimated from these two models. However, because investor perceptions affect the DCF estimate of returns, changes in investor confidence without accompanying changes in firm risk can affect the DCF estimate without changing the CAPM estimate. High growth firm returns are more likely to incorporate changes in investor perception because more of their value is generated from realization of future growth opportunities. In this research, I study whether investor sentiment affects the DCF estimate of stock return more than the CAPM estimate, and whether this impact is more pronounced for high growth firms. I find results consistent with this hypothesis. I find that investor sentiment causes a divergence between the CAPM and DCF estimates of stock returns, and this divergence is higher for high growth firms compared to low growth firms. My findings suggest that high growth firm stock prices are more prone to distortions due to hype or investor pessimism

THE EFFECTS OF THE BASE EROSION AND PROFIT SHIFTING (BEPS) ACTION 13 ON TRANSFER PRICING PRACTICES: A COMPARATIVE EMPIRICAL STUDY OF NEW ZEALAND AND VIETNAM

This thesis was shaped from Action 13 of the recent Base Erosion and Profit Shifting (BEPS) project adopted by the Organisation for Economic Co-operation and Development (OECD) and G20 countries to prevent profit shifting by multinational enterprises (MNEs). In response to the BEPS Action 13, New Zealand and Vietnam have recently introduced new transfer pricing rules. As little research has been done to examine the effects of the BEPS Action 13 on the transfer pricing landscape of respective countries, the main objective of this study is to understand how the New Zealand and Vietnamese governments have reacted to and adapted the BEPS Action 13 and what tax consultants and taxpayers in both countries think about the new transfer pricing regulations. This study is exploratory in nature. As such, a qualitative case study approach has been adopted using institutional theory as a theoretical framework. Semi-structured interviews were conducted with two tax officers and ten transfer pricing consultants in both countries to identify the differences and similarities, and to draw conclusions. Other sources of publicly available data were also used to support the study

Adjoint methods for obstacle problems and weakly coupled systems of PDE

The adjoint method, recently introduced by Evans, is used to study obstacle problems, weakly coupled systems, cell problems for weakly coupled systems of Hamilton--Jacobi equations, and weakly coupled systems of obstacle type. In particular, new results about the speed of convergence of some approximation procedures are derived
