There exist dual listed stocks which are issued by the same company in some stock markets. Although these stocks bare the same firm-specific risks and enjoy identical dividends and voting policies, they are priced differently. Some previous studies show this seeming deviation from the law of one price can be solved by allowing different expected returns and market prices of risk for investors h...

The purpose of this paper is to study the impact of the monetary policy instruments and to explore the extent to which macroeconomic variables affect the Romanian stock market’s behaviour in the 2000 – 2011 period with a GARCH-family system of simultaneous equations. Another rational of this research is to determine whether stocks are a good hedge against inflation on the Romanian financial mar...

the theoretical base of this paper is the economic growth model that completed with capital stocks (private and public) and human capital. at the first, hypothesis test about constant returns to scale is studied, and then the related variables with macroeconomic policies are added to the model. the results show that 1) the aggregate production function exhibits increasing returns to scale, 2) p...

Investor decision making has always been affected by two factors: risk and returns. Considering risk, the investor expects an acceptable return on the investment decision horizon. Accordingly, defining goals and constraints for each investor can have unique prioritization. This paper develops several approaches to multi criteria portfolio optimization. The maximization of stock returns, the pow...

this article investigates fluctuations in stocks prices at tehran stock exchange, assuming that investors' utility stems from fluctuations in value of stocks as well as consumption. thus, the two behavioral phenomena discussed in prospect theory, i. e. loss aversion and house money effect, were factored into consumption-based asset pricing model and investor's utility function, which ...

It has been proposed that recognition can form the basis of simple but ecologically rational decision strategies (Gigerenzer & Goldstein, 1996). Borges, Goldstein, Ortmann, & Gigerenzer (1999) found that constructing share portfolios based on simple name recognition alone often yielded better returns than the market index. We describe four studies with seven samples of participants from three c...

Does Noise Create the Size and Value Effects? Black (1986) and Summers (1986) suggest that the price of a stock can deviate from its intrinsic value by a random noise. In this paper, we show that a stock with such a noise has a higher expected return when its market capitalization or price-dividend ratio is low, because a low market capitalization or price-dividend ratio is a signal that the no...
