Wavelet based multi-scale analysis of financial time series has attracted much attention, lately, from both the academia and practitioners from all around the world. The unceasing metamorphosis of the discipline of finance from its humble beginning as applied economics to the more sophisticated...

In this paper, we examine an exchange economy with a financial market composed of three assets: a share of a stock, an European call option written on the stock, and a riskless bond. The financial market is assumed to be incomplete and the option is not a redundant asset. In such a case the...

We consider a single-period financial market model with normally distributed returns and the presence of heterogeneous agents. Specifically, some investors are classical Expected Utility Maximizers whereas some others follow Cumulative Prospect Theory. Using well-known functional forms for the...

We study the dynamics of a Lucas-tree model with finitely lived agents who “learn from experience.” Individuals update expectations by Bayesian learning based on observations from their own lifetimes. In this model, the stock price exhibits stochastic boom-and-bust fluctuations around the...

This paper studies the effects of multiple investment horizons and investors' bounded rationality on the price dynamics. We consider a pure exchange economy with one risky asset, populated with agents maximizing CRRA-type expected utility of wealth over discrete investment periods. An investor's...

The Efficient Market Hypothesis (EMH) asserts that the prices of securities correctly and fully reflect all available information. But there are some empirical facts in capital markets thatEMHis not able to explain. Recently, a lot of new models with heterogeneous agents in expectation formation...

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