Heterogeneous consumption in OLG model with horizontal innovations

Computation of Equilibria in OLG Models with Many Heterogeneous Households

This paper develops a decomposition algorithm by which a market economy with many households may be solved through the computation of equilibria for a sequence of representative agent economies. The paper examines local and global convergence properties of the sequential recalibration (SR) algorithm. SR is then demonstrated to efficiently solve AuerbachKotlikoff OLG models with a large number o...

The Diamond OLG Model

Labor Unions, Unemployment, and Inequality in an OLG-Model with Heterogeneous Agents

As a consequence of falling relative demand for low skilled labor in the OECD, people with no or minor qualification experience a deterioration of their economic situation. While flexible labor markets have led to higher wage differentials in the USA, the major problem of most European countries is the high rate of unemployment of the low skilled. To integrate currently discussed determinants o...

Technology Adoption in an OLG model with forward-looking agents

We investigate the effects of forward looking behaviour in technology adoption. The setup is an overlapping generation model where agents choose between two alternative networks taking in consideration the installed base as well as the expected base. In other words users not only keep into account the actions of previous players, but also form expectations over future generations’ choices befor...

Growth through heterogeneous innovations

We study how external versus internal innovations promote economic growth through a tractable endogenous growth framework with multiple innovation sizes, multi-product firms, and entry/exit. Firms invest in external R&D to acquire new product lines and in internal R&D to improve their existing product lines. A baseline model derives the theoretical implications of weaker scaling for external R&...
