The birth and death of firms is one of the main features of the business cycle. Yet mainstream DGSE macroeconomic models mostly ignore this phenomenon, thereby excluding any potential impact of economic policy on the probability of the birth and death of firms. Those DGSE models that do allow for this phenomenon do so at the cost of drastic simplifications, which effectively rule out causal links between the strategic interaction of industrial firms and the macroeconomy. This innovative new book develops a bottom-up, agent-based framework that shows how strategic interactions at the level of oligopolistic firms, and even at the level of individuals, affect entire industrial sectors and the equilibrium of the macroeconomy. It will appeal to academic researchers and graduate students working in computational economics, agent-based modelling and econophysics, as well as mainstream economists interested in learning more about alternatives to DGSE models in macroeconomics.

This book relates the literatures of finance, industrial economics and investment to the theoretical framework of the 'credit view'. Firstly it is assumed that banks' decisions concerning their assets are seen as at least as relevant as their decisions concerning their liabilities. Secondly, securities and bank credit are considered to be highly imperfect substitutes. In this regard it is important to investigate the way industrial and financial sectors interact. In particular, how is the macroeconomy affected by the phenomenon of 'securitization' and by exogenous changes in the industrial structure of the credit market. The interactions between real and financial sectors are also analysed from the point of view of the industrial firm, in a model where the investment and financial decisions of the firm are taken simultaneously.
