The paper deals with non-linear dynamics of an extended Kaldor model including not only production and capital stock dynamics but also the interest rate and price dynamics with an adaptive expectation of inflation. Presented structure of the model is described by the system of the five...

This paper aims at contributing to the research agenda on the sources of price stickiness, showing that the adoption of nominal price rigidity may be an optimal firms' reaction to the consumers' behavior, even if firms have no adjustment costs. With regular broadly accepted assumptions on...

Over the years, optimal taxation has been extensively discussed, and a major focus has been on the question of whether the optimal capital income tax rate is zero in long-run equilibrium. This paper addresses this issue in the context of a model of vintage capital with technical change and the...

This paper explores the role that recessions play in resource allocation. The conventional cleansing view, advanced by Schumpeter in 1934, argues that recessions promote more efficient resource allocation by driving out less productive units and freeing up resources for better uses. However,...

Recent empirical findings have emphasized post entry growth of survivors, as opposed to exit of inefficient and small firms, as the main source of growth over time in the average size of a cohort of entering firms. In this paper, as an explanation for the significant growth of survivors, we...

In this paper we study the effects of social networks on wage inequality and aggregate production. In particular, we consider a simplified version of the model by Calvò-Armengol and Jackson (2003), with good and bad jobs and skilled and unskilled workers. Our findings are: i) increasing the...

In this paper we study how some characteristics of the topology of social networks affect the dynamics of output and inequality. Our main findings are: I) symmetric networks with ``strong ties'' produce higher output and lower inequality than asymmetric networks; II) the introduction of ``weak...

An agent-based Keynesian laboratory is built with a twofold purpose; to further investigate the ideas of Keynes and check them for internal consistency, and secondly to investigate the stability of a Keynesian world and explore the scope for economic policy. The laboratory is developed in Swarm...
