We investigate the impact of product market competition on firms' systematic risk. Using a measure of total product market similarity, we document a strong negative link between market power and market betas. There is a more than threefold increase in the effect during the most recent...

This purpose of this paper is to present the expected equity returns for the Indian stock market for the benefit of investors, who may then compare such returns with actual market returns to evaluate whether the Indian stock market provides returns in excess of expectations. Both the capital...

This paper investigates the instability of stock beta in Dhaka Stock Exchange over the period of 2000 to 2007. Ordinary least square estimates of CAPM beta and Dimson beta of individual securities for 3, 4 and 8-years holding periods are not found statistically significantly different from each...

The linear relation between risk and rate of return in Vietnam stock market is tested for the falling period 2007-2009 based on adjusted-price data. As a result, the failure of the test shows that VN-Index, conventionally regarded as the "market portfolio", is not mean-variance efficient to the...

This paper studies how expected returns interact with product market competition. We present a model in which product market competition is jointly captured by the industry concentration and the average markup. We then provide empirical evidence consistent with three channels that explain the...

This paper analyzes the optimal investment strategy of two firms confronted with the option to adopt a new technology. I add two key features: location and learning. A firm gains relative advantage entirely due to its geographic placement - this is the location benefit. Firms also learn from the...

We consider an economy populated by CARA investors who trade, accounting for their price impact, multiple risky assets with arbitrary distributed payoffs. We propose a constructive solution method: finding the equilibrium reduces to solving a linear ordinary differential equation. With market...

We develop an endogenous growth model with heterogeneous firms facing financial frictions, where misallocation emerges explicitly as a crucial endogenous state variable and plays a significant role in driving economic growth through the valuation channel. The model illustrates that transient...

In a passive investing strategy through indexation, the portfolio performance will depend largely on the ability to choose the best index. In this paper, we study the performance of four of the main stock indices in Mexico with the intention of selecting the best one for a passive investing...

Many postulated relations in finance imply that expected asset returns strictly increase in an underlying characteristic. To examine the validity of such a claim, one needs to take the entire range of the characteristic into account, as is done in the recent proposal of Patton and Timmermann...
