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...

The goal of the paper consists in investigating if comovements in some selected time series are common to various countries and periods of time. To do so, we use 18 economic time series (GDP and demand components, employment and wages, money and prices, interest rates and stock prices) between...

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...

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, we model an agent-based economy in which heterogeneous agents (firms and a bank) interact in the financial markets. The heterogeneity is due to the balance sheet conditions and to size. In our simulations, at the aggregate level, output displays changes in trend and volatility...

This book deals with the application of wavelet and spectral methods for the analysis of nonlinear and dynamic processes in economics and finance. It reflects some of the latest developments in the area of wavelet methods applied to economics and finance. The topics include business cycle...

Aggregate empirical evidence on the financial accelerator effect is highly debated. In this study, we apply multiresolution analysis, based on the continuous wavelet transform, to investigate the relationship between aggregate net worth and credit market variables in the commercial and...
