The consumption capital asset pricing model is the standard economic model used to capture stock market behavior. However, empirical tests have pointed out to its inability to account quantitatively for the high average rate of return and volatility of stocks over time for plausible parameter...

This paper develops a new method for solving both equity premium and risk free rate puzzles based on the standard utility function. The method for solving the equity premium puzzle in accordance with Mehra and Prescott (1985) needs to be simultaneously consistent with the method for solving the...

Rational bubbles are believed to be fragile and unable to explain the trading frenzy associated to price run-ups. With limited enforcement of credit contracts and endogenous debt limits designed to prevent default and allow for maximal credit expansion, a large class of bubbles can be introduced...

A major research initiative in finance focuses on the determinants of the cross-sectional and time series properties of asset returns. With that objective in mind, asset pricing models have been developed, starting with the capital asset pricing models of Sharpe (1964), Lintner (1965), and...

This paper studies the role of credit market development in an economy with credit frictions. I examine how the provision of credit in connection with collateral assets affects both economic performance and business cycle volatility. First, I analyse the macroeconomic implications of an...

The present project introduces the possibility of default on the trading contracts in an infinite horizon incomplete markets model, relaxing the usual assumption made in the literature with respect to the trading limits, which are chosen to be fixed or independent of the characteristics of the...

Stock prices often diverge from measures of fundamental value, which simple present value models fail to explain. This paper tries to find causes for these long-run price movements and their persistence by estimating a STAR model for the price-earnings ratio of the S&P500 index for 1961Q1 -...

In this paper we examine the difference between T-Bill returns and common stock returns in Turkey. We observe that there is a bond premium in Turkey unlike the equity premia in developed countries. As an attempt to explain this surprising observation, we incorporate inflation risk and default...

This paper assesses the quantitative impact of ambiguity on the historically observed financial asset returns and prices. The single agent, in a dynamic exchange economy, treats the conditional uncertainty about the consumption and dividends next period as ambiguous. We calibrate the agent's...
