This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form of blocking patents. We show that patent...

This study analyzes how patent protection affects innovation in an R&D-based growth model with elastic labor supply. We find that increasing patent breadth may generate an inverted-U effect on innovation depending on whether the model features the knowledge-driven or lab-equipment innovation...

We work out the mechanism that makes public debt affect the allocation of resources in the long-run. To do so we analyze an AK growth model with elastic labor supply and a government sector. The government levies a distortionary income tax and issues bonds to finance lump-sum transfers and...

This paper analyzes the public debt situation in Japan, Germany and the United States by reflecting their respective debt history and by analyzing whether the governments pursue a sustainable debt policy. Starting point of the analysis are theoretical considerations about conditions guaranteeing...

We analyze the general-equilibrium e§ects of alternative regimes of access rights over renewable natural resources ñnamely, open access versus full property rights ñon the pace of development when economic growth is endogenously driven by both horizontal and vertical innovations. Resource...

We analyze the general-equilibrium effects of alternative regimes of access rights over renewable natural resources – namely, open access versus full property rights on the pace of development when economic growth is endogenously driven by both horizontal and vertical innovations. Resource...
