We examine how irreversible capital reduces the possibility of a duopoly to sustain implicit collusion by grim strategies, when the product is homogenous and firms compete in quantities. Compared with the case of reversible capital, there are two countervailing effects: Deviation from an...

This paper analyzes how monetary policy in an overlapping generations model can be designed to avoid inflationary consequences of anticipated changes of monetary policies. Avoiding these inflationary consequences will require a once and for all increase (decrease) in monetary growth immediately...

Collective consumption decisions taken by the members of a household may prove inefficient. The impact on market performance depends on whether household inefficiencies are caused by inefficient net trades with the market or by inefficient distribution of resources within households. Inefficient...

We present a new approach to endogenizing technological spillovers. Firms choose levels of a cost-reducing innovation from a continuum before they engage in competition for each other's R&D-employees. Successful bids for the competitor's employee then result in higher levels of cost reduction....

We examine wage-bargaining in a two-sector economy when employers and labor unions in each sector are not always aware of all general equilibrium feedback effects. We show analytically that if agents only consider labor demand effects, low real wages and low unemployment result. With an...

We develop a product market theory that explains why firms invest in general training of their workers. We consider a model where firms first decide whether to invest in general human capital, then make wage offers for each others' trained employees and finally engage in imperfect product market...

We examine economic growth, inequality and education when the wellspring of growth is the formation of human capital through a combination of the quality of child-rearing and formal schooling. The existence of multiple steady states is established, including a poverty trap, wherein children work...

In this paper we study how promoting product market competition by reducing mark-ups or by increasing productivity are able to complement labor market reforms. We use a simple general equilibrium model with different types of labor. The bottom-line of the paper is that product market reforms...
