Schumpeter asserted that there were two types of business cycle theories: one in which cycles reflected dampened economic behavior and another in which cycles reflect explosive economic behavior. Both of these theories allowed that cycles could be either monotonic or oscillating. In this working...

In this paper we present the basics of a research program aimed at providing microfoundations to macroeconomic theory on the basis of computational agentbased adaptive descriptions of individual behavior. To exemplify our proposal, a simple prototype model of decentralized multi-market...

The firmly established evidence of right-skewness of the firms’ size distribution is generally modelled recurring to some variant of the Gibrat’s Law of Proportional Effects. In spite of its empirical success, this approach has been harshly criticized on a theoretical ground due to its lack...

Power law behavior is an emerging property of many economic models. In this paper we emphasize the fact that power law distributions are persistent but not time invariant. In fact, the scale and shape of the firms' size distribution fluctuate over time. In particular, on a log–log space, both...

This paper describes an empirical study of the implications of agents' heterogeneity for theories of macroeconomic fluctuations based on the role of financial variables. Models of explicit distribution dynamics are applied to company account data from a panel of US manufacturing firms to...

We developed a multi country agent based simulation model with endogenous incremental technological change. Macroeconomic dynamics derive from simple behavioral and interacting rules defining the actions of adaptive firms, banks and households (Delli Gatti et al., 2008; Riccetti et al., 2014; Caiani et...

Die zunehmende Vernetzung von Rechnern über das Internet lies die Vision von Application Layer Netzwerken aufkommen. Sie umfassen Overlay Netzwerke wie beispielsweise Peer-to-Peer Netzwerke und Grid Infrastrukturen unter Verwendung des TCP/IP Protokolls. Ihre gemeinsame Eigenschaft ist die...

In this paper the authors focus on credit connections as a potential source of systemic risk. In particular, they seek to answer the following question: how do we find densely connected subsets of nodes within a credit network? The question is relevant for policy, since these subsets are likely...

This paper is aimed at investigating the effects of government intervention through unemployment benefits on macroeconomic dynamics in an agent-based decentralized matching framework. The major result is that the presence of such a public intervention in the economy stabilizes the aggregate...
