In many traditional financial and economic models, economic agents are assumed to make decisions using expected lifetime utility under rational expectations, where rational expectations are assumed to be formed on the basis of sufficient knowledge of the data generating process. But the mere...

Most recent studies of dynamic macroeconomic relationships focus on models derived from optimising behaviour by economic agents. In most of these models, the eigenvalues of the associated dynamical system are real-valued and so the time-path of the system exhibits monotonic or near-monotonic...

This notes proposes an approximation to the consumption function in the buffer-stock model.

This paper extends Gertler's (1999) tractable overlapping generations model by allowing for imperfect labour markets and distortionary taxation. Furthermore, we allow for stochastic variation in demographic structure. The model is then used to study demographic change in a small open economy of...

We present a quantitative analysis of the effects of population aging and pension reform on international capital markets. First, demographic change alters the time path of aggregate savings within each country. Second, this process may be amplified when a pension reform shifts old-age provision...

Investment decision-making is modeled by means of a Kohonen neural net, whose neurons represent firms as decision-makers. Thus, the network reconstructs collective decision-making by the productive system. This model focuses on the decision to invest in novel fields of activity, which requires...
