Development of macroeconomic modelling methods: Incorporating ex-post heterogeneity to Dynamic Stochastic Generel Equlibrium Models

realization time: 09.2012-04.2016

The aim of the project was to develop a novel mathematical method that will facilitate the introduction of heterogeneity of economic agents into otherwise standard macroeconomic general equilibrium models. The method was rather flexible and it was possible to use it to study a wide array of problems, ranging from changes in income inequality in the business cycle to  the role of liquidity contraints in the financial sectore in the propagation of recessions.  In the context of the project, we developed a heterogeneous firm model with on-the-job search and financial frictions which will be used to analyze labour market flows.   This project has received funding from the National Science Centre under decision no DEC-2011/03/B/HS4/05895

2016-05-20 Business cycles and on the job search
authors:    /   / 
We study steady state and business cycle properties of a model with heterogeneous firms and on-the-job search in the spirit of Moscarini and Postel-Vinay (2012). We extend the setup by including capital in the production function and show how this change influences model properties. The ...
2016-05-19 On the job search and working capital
authors:    / 
We study the steady-state effects of working capital channel on the distribution of wages and reallocation of workers across employers. We first show that in a simple Burdett-Mortensen on-the-job search model, working capital channel matter for wage offers distributions of firms and wage distribution of ...
