We investigate how stochastic asset price dynamics with herding and financial constraints explains the presence of a <italic>period of financial distress</italic> (PFD) following the peak and preceding the crash of a bubble [Charles P. Kindleberger, <italic>Manias, Panics, and Crashes: A History of Financial Crisis</italic>, 4th...

In this paper, we investigate the presence of rationalherding on asset price dynamics during the intra-day trading withheterogeneous interacting agents, whose information set is notcomplete. In the model, individual probability measures offinancial investment strategies are defined using...

In this paper we show how a simple modification of a well-known multiplicative process of firms' growth, taking into account common and idiosyncratic elements, allows to reconcile an old aggregate-sector puzzle (Quandt, 1966) on firms'' size distribution reported in the literature.

The purpose of this paper is to give some insights about the debate between Aivazian and Callen (1981, 2003) and Coase (1981) regarding the empty core problem. In particular our analysis concerns the role played by transaction costs in the debate. By maintaining the Aivazian-Callen transaction...

This paper investigates some central issues of monetary policy by offering a model in which a central bank tries to stabilize fluctuations in aggregate output and inflation in an adaptive complex economy. We resort to evolutionary algorithms to model the central bank behaviour under discretion,...

Our analysis, conducted using the GDP and the GDP deflator time series (OECD source; 1960–2001) for the G7 countries, shows the robustness of the negative covariance between the GDP and its deflator, but only over long run horizons. Through wavelet decomposition we evaluate the price–output...
