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 provide sufficient conditions and necessary conditions for stability of an economy under structural mixed recursive least squares/stochastic gradient heterogeneous learning of agents with possibly different degrees of inertia. We have found a unifying condition which is sufficient for...

In our dynamic optimizing sticky price model, agents are heterogenous with regard to their assets and their income. Unanticipated inflation redistributes income and wealth. In order to model the wealth distribution, we study a 60-period OLG model with aggregate uncertainty. A positive technology...

This paper introduces a simulation model extending the well known Capital Asset Pricing Model by Sharpe and Lintner. Investors are modeled as multi-period forward looking portfolio optimizers. However, the future is not known \emph{a priori}, but has to be modeled and estimated. We allow agents...

Price forecasting and trading strategies modelling are examined with major international stock indexes under different time horizons. Results demonstrate that an accurate prediction is equally important as a stable saving rate for long-term survivability. The best economic performances are...

Foreign exchange markets regularly display severe bubbles. This paper explores whether or not so-called target zone interventions are an effective tool for central banks to stabilize the exchange rate. We define such intervention operations as buying/selling an undervalued/overvalued currency...

In this paper, we propose a heterogeneous interacting agent model of a sequential monetary production economy. We use a basic dynamic flow model in an interacting agent context. The economy is assumed to be closed. There are three classes of agents: a single homogeneous representative consumer,...

We develop a model in which boundedly rational agents apply technical and fundamental analysis to identify trading signals in two different speculative markets. Whether an agent trades and, if so, in which market with which strategy depends on profit considerations. As it turns out, an ongoing...

Fluctuations of representative agent economies are not very costly. So if business cycles matter, it must be because agents face uninsured idiosyncratic risk which is somehow worsened by aggregate fluctuation. Idiosyncratic risk could be counteracted either through aggregate stabilization or...
