This article estimates stochastic volatility jump-diffusion processes using the continuous empirical characteristic function method based on the Joint characteristic function and the Marginal characteristic function. The emphasis is on the specification of jumps in the asset log-price. Out of...

We derive a closed-form asymptotic expansion formula for option implied volatility under a two-factor jump-diffusion stochastic volatility model when time-to-maturity is small. Based on numerical experiments we describe the range of time-to-maturity and moneyness for which the approximation is...

Bayesian Model Averaging (BMA) has recently been discussed in the financial literature as an effective way to account for model uncertainty. In this paper we compare BMA to a new model uncertainty framework introduced by Yang (2004), called Aggregate Forecasting Through Exponential Reweighting,...

We consider a pure exchange economy with incomplete information. Some agents in the economy display learning bias and over- or underreact to the arrival of new information. We study, by simulation, the distribution of irrational agents' consumption shares. We find that over a reasonable horizon...

The main contribution of this study is to develop a dynamic general equilibrium model linking financial markets to the real economy. In search of a unified framework, this study finds that a model with internal habit memory is able to generate asset pricing and business cycle predictions that...

Recent studies have found unmeasured intangible capital to be large and important.In this paper we observe that by nature intangible capital is also very different from physical capital. We find it plausible to argue that the accumulation process for intangible capital differs significantly from...

The classic Lucas asset pricing model with complete markets stresses aggregate risk and, hence, fails to investigate the impact of agents heterogeneity on the dynamics of the equilibrium quantities and measures of trading volume. In this paper, we investigate under what conditions...

We analyze the implications of dynamic flows on a mutual fund manager's portfolio decisions. In our model, a myopic investor is allowed to dynamically allocate capital between a riskless asset and an actively managed mutual fund who charges fraction of fund fees. The presence of dynamic flows...

This paper studies the role of strategy and the order book market mechanism in price dynamics and the order flow behaviour. To this end we analyse a zero-intelligence agent model of a dynamic limit order market. Stylised facts of limit order markets are shown to be influenced and, in some cases,...

The main objective of this work is to develop a general equilibrium business cycle model linking financial and real estate markets to the macro economy. The ability of a production economy to account simultaneously for asset pricing, business cycle and real estate market facts is then evaluated...
