Abstract: |
This paper studies how the interplay between technological shocks and
financial variables shapes the properties of macroeconomic dynamics. Most of
the existing literature has based the analysis of aggregate macroeconomic
regularities on the representative agent hypothesis (RAH). However, recent
empirical research on longitudinal micro data sets has revealed a picture of
business cycles and growth dynamics that is very far from the homogeneous one
postulated in models based on the RAH. In this work, we make a preliminary
step in bridging this empirical evidence with theoretical explanations. We
propose an agent-based model with heterogeneous firms, which interact in an
economy characterized by financial-market imperfections and costly adoption of
new technologies. Monte-Carlo simulations show that the model is able jointly
to replicate a wide range of stylised facts characterizing both macroeconomic
time-series (e.g. output and investment) and firms' microeconomic dynamics
(e.g. size, growth, and productivity). |
