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...

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...

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...

This paper studies the effects of social insurance policies on the level and distribution of welfare and resources in a general equilibrium model of a closed economy with a continuum of agents and moral hazard. In order to simulate the welfare-state tradeoff between efficiency and equality, I...

This paper develops the notion of a Large Type Limit (LTL) describing the average behavior of adaptive evolutionary systems with many trader types. It is shown that generic and persistent features of adaptive evolutionary systems with many trader types are well described by the large type limit....

This paper develops and solves a general equilibrium business cycle model with on-the-job search and wage rigidity arising from long-term labor contracts. Labor search models without these features have been criticized for failing to generate procyclical movements in job vacancies and...
