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...

In this paper we apply the wavelets methodology to the analysis business cycle fluctuations. The analysis is performed using the industrial production index in 6 developed countries between 1960-2002. We produce an orthogonal decomposition of industrial output series by time scale over six...

Standard macroeconomics, based on a reductionist approach centered on the representative agent, is badly equipped to explain the empirical evidence where heterogeneity and industrial dynamics are the rule. In this paper we show that a simple agent-based model of heterogeneous financially fragile...

In this paper, extending the framework originally put forward by Greenwaldand Stiglitz (1988, 1990, 1993), we have developed a theoretical framework in which the financial conditions affect the capital accumulation decisions of the firm. In contrast to Greenwald and Stiglitz we allow for an...

In macroeconomic models with financial constraints (see, for instance, Greenwald and Stiglitz, 1993; Bernanke, Gertler and Gilchrist,1998; Kiyotaki and Moore,1997) firms' supply decisions depend upon the degree of financial robustness/fragility, which is identifed and measured in different ways. In the...
