Within a Kaleckian framework, Harrodian instability and a constant long-run utilization rate are reconciled with the principle of effective demand by endogenizing the capacity output-capital ratio. Its change over time is argued to be a positive function of the utilization rate. As stabilizing...

The main task of this work is to develope a model able to encompass, at the same time, Keynesian, demand-driven, and Marxian, profit-driven determinants of fluctuations. Our starting point is the Goodwin's model (1967), rephrased in discrete time and extended by means of a coupled dynamics...

We show that an otherwise standard one-sector real business cycle model with variable capital utilization and mild increasing returns-to-scale is able to generate qualitatively as well as quantitatively realistic aggregate fluctuations driven by news shocks to two formulations of future...

Post-war US data show that consumption growth Granger causes output and investment growth. This is puzzling if technology is the driving force of the business cycle. I ask whether general equilibrium models with information frictions and non-technology shocks can rationalize the observed causal...

The paper recognizes that expectations and the process of their formation are subject to standard decision making and are determined as a part of equilibrium. Accordingly, the paper presents a basic framework in which the form of expectation formation is a choice variable. At any point in time...

Recessions are often accompanied by spikes of corporate default and prolonged declines of business credit. This paper shows that credit and default cycles can result from variations of self-fullling beliefs about credit market conditions. We develop a tractable macroeconomic model in which...

This paper presents the business cycle model that Trygve Haavelmo developed as part of his research program in macroeconomic and monetary theory. Driven by a mismatch between the marginal return to capital and the rate of return required by capital owners, this model generates endogenous cycles....

We add agency costs as in Carlstrom and Fuerst (1997) into a two-country, two-good international business-cycle model. In our model, changes in the relative price of investment arise endogenously. Despite the fact that technology shocks are uncorrelated across countries, the relative price of...

Big technological improvements in a new, secondary sector lead to a period of excitement about the future prospects of the overall economy, generating boom-bust dynamics propagating through credit markets. Increased future capital prices relax collateral constraints today, leading to a boom...
