there are different strategies for selecting stocks, and different investors use different strategies according to their risk tolerance or their expected rate of return. in this study, the profitability of a broad range of stock se-lection strategies in tehran stock exchange over the period 1370-1383, has been examined, and it has been investigated whether the successful strategies in other cou...

Despite their popularity as proxies of expected returns, the implied cost of capital’s (ICC) measurement error properties are relatively unknown. Through an in-depth analysis of a popular implementation of ICCs by Gebhardt, Lee, and Swaminathan (2001) (GLS), I show that ICC measurement errors can be not only nonrandom and persistent, but can also be associated with firms’ risk or growth charact...

Decision making requires an actor to not only steer behavior towards specific goals, but also determine the optimal vigor of performance. Current research and models have largely focused on the former problem of how actions are directed, while overlooking the latter problem of how they are energized. Here, we designed a self-paced decision-making paradigm that showed that rats' performance vigo...

This paper documents that the earnings yield and book-to-price combine to predict equity returns in a way that is consistent with the rational pricing of risk. It is well known that earnings yields predict returns in the cross-section, consistent with standard formulas that show that the earnings yield equals the required return when there is no expected earnings growth beyond that from retenti...

This paper aims to investigate the uncertainty factors that impact the collection strategy of a remanufacturing closed-loop supply chain. The basis of this type of supply chain is the collection of used products, without which the remanufacturing of new products would be out of the question. In this paper, we considered the effect of stochastic disturbance on the collection process in a closed-...

Stochastic linear quadratic portfolio selection problem for relative return process is to maximize the expected linear quadratic function of the relative return process. We introduce the benchmark process and define the relative return process as quotient which is obtained when the wealth process is divided by the benchmark process. We derive the optimal portfolio in closed form via investigati...
