In this work we study the granular origins of business cycles and their possible underlying drivers. As shown by Gabaix (2011), the skewed nature of firm size distributions implies that idiosyncratic (and independent) firm-level shocks may account for a significant portion of aggregate...

The total output of an economy usually follows cyclical movements which are accompanied by similar movements in stock prices. The common explanation relies on the demand side. It points out that stock market wealth drives consumption which triggers production afterwards. This paper focuses on...

Do fiscal stabilization policies affect the long-term growth of the economy? If so, are the long-term effects growth-enhancing or growth-reducing? These questions have again become relevant to the political and academic debate since governments have been forced to spend considerable funds for...

The paper presents a new method to solve DSGE models with a great number of heterogeneous agents. Using tools from systems and control theory, it is shown how to reduce the dimension of the state and the policy vector so that the reduced model approximates the original model with high precision....

We propose an agent-based computational model defining the following dimensions of structural change - organisation of production, technology of production, and product on the supply side, and income distribution and consumption patterns on the demand side - at the microeconomic level. We define...

This paper presents an Agent-Based Model (ABM) that seeks to explain the concordance of sluggish growth of productivity and of real wages found in macro-economic statistics, and the increased dispersion of firm productivity and worker earnings found in micro level statistics in advanced...

The aggregate saving indicator does not directly reflect changes in individuals' microeconomic behavior. From the official statistics' point of view, households choosebetween spending, which generates additional income and consumption in the economy, and setting money aside, which does not....

This paper extends the endogenous-growth agent-based model in Fagiolo& Dosi (2003) to study the finance-growth nexus. We explore industries where firms produce a homogeneous good using existing technologies, perform R&D activities to introduce new techniques, and imitate the most productive...
