This paper studies a two-sector model of learning-by-doing that is partially transferable between sectors. There is a potential efficiency gain from intersectoral turnover when the sectors have different complementary production costs or learning curves of different steepness. If workers are...

The size distributions of many economic variables seem to obey the double power law, that is, the power law holds in both the upper and the lower tails. I explain the emergence of the double power law - which has important economic, econometric, and social implications - using a tractable...

We analyze a simple and tractable model of occupational choice in the presence of credit market imperfections. We examine the effect of parameters governing technology and transaction costs, and history, in terms of the initial wealth distribution, in determining the long-term wealth...

This paper will review the issue of heterogeneity of agents and incomplete markets in macroeconomics. Central idea of this paper is the notion that representative agent models were wrong turn for modern macroeconomics especially for general equilibrium model (some individuals are some are not...

We study the impact of market incompleteness and bounded rationality on the effectiveness of make-up strategies. To do so, we simulate a heterogeneous-agent New Keynesian (HANK) model with reflective expectations and an occasionally-binding effective lower bound (ELB) on the policy rate. Our...

This paper reviews recent approaches to modeling the labour market and assesses their implications for in.ation dynamics through both their effect on marginal cost and on price-setting behaviour. In a search and matching environment, we consider the following modeling setups: right-to-manage...

This paper analyzes whether differences in institutional structures on capital markets contribute to explaining why some OECD-countries, in particular the Anglo-Saxon countries, have been much more successful over the last two decades in producing employment growth and in reducing unemployment...
