This study provides new estimates of systematic risk and the cost of equity capital for the pharmaceutical, biotechnology, and medical device sectors using data for firms with publicly-traded stock on U.S. exchanges during 2001-2005 and 2006-2008. Two frameworks are employed for estimating firms’ risk and the cost of equity capital: (1) the capital asset pricing model, and (2) the Fama-French t...

This paper provides an alternate method of evaluating portfolio performance of stock pricing models. We apply Pitman Closeness Criterion to compare the accuracy of three popular pricing models. This comparison is used to assess which, if any, model outperforms the others. In assessing model performance over a long period of time, we find that the Fama-French three-factor model and the Carhart f...

Using an agent-based multi-asset artificial stock market, we simulate the survival dynamics of investors with different risk preferences. It is found that the survivability of investors is closely related to their risk preferences. Among the eight types of investors considered in this paper, only the CRRA investors with RRA coefficients close to one can survive in the long run. Other types of a...

The purpose of this paper is to show that the problem of trust relates to all three levels of financial engagement by a retail investor. (1) Engagement with the adviser who advises on financial products. (2) Engagement with the financial institutions that produce the financial products. (3) Engagement with the stock markets in which the financial products are invested. It is proposed that these...

Entrepreneurs often face undiversifiable idiosyncratic risks from their business investments. Motivated by this observation, we extend the standard real options approach to investment to an incomplete markets environment and analyze the joint decisions of business investments, consumption-saving and portfolio selection. We show that precautionary saving motive affects the investment timing deci...

a r t i c l e i n f o JEL classification: C52 E44 G12 Keywords: Consumption based asset pricing model Multi-factor model Panel estimation Fixed effects This article considers a panel framework to test consumption based asset pricing models driven by a US stock market reference for a number of developed economies. Specifically, we focus on a linearized form of what might be seen as a consumption...

We introduce intermediation frictions into a Lucas (1978) asset pricing model in order to study the effects of low capital in the intermediary sector on asset prices. Our model shows that low intermediary capital can increase risk premia, Sharpe ratios, volatility and comovement among intermediated assets. Reductions in intermediary capital also lead to a flight-to-quality in which intermediari...
