In this paper we apply the wavelets methodology to the analysis of the industrial production index of the G-7 countries between 1961:1-2005:5. The analysis is performed using a multi-scaling approach which decomposes the variance of the industrial production index and the covariance between the...

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...

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...

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...

With this paper we provide, for the first time to our knowledge, micro-level evidence on the negative linkage between firm complexity and volatility. A higher sophistication level of a firm's export basket reduces its output fluctuations. When focusing on a sample of exporting and non exporting...

We explore the dynamics of default cascades in a network of credit interlinkages in which each agent is at the same time a borrower and a lender. When some counterparties of an agent default, the loss she experiences amounts to her total exposure to those counterparties. A possible conjecture in...

Borrowing from our experience in agent-based computational economic research from `bottom-up', this paper considers economic system as multi-level dynamical system that micro-level agents' interaction leads to structural transition in meso-level, which results in macro-level market dynamics with...

In this paper we present a macroeconomic microfounded framework with heterogeneous agents – households, firms, banks – which interact through a decentralized matching process presenting common features across four markets – goods, labor, credit and deposit. We study the dynamics of the...
