A growth model, in which economic growth is driven by R&D activities, is constructed to analyse issues related to the riskiness of R&D. It is shown that when R&D are risky strongly-risk-averse behaviour may suffocate the potential growth of a closed economy if risk-sharing arrangements are...

This paper studies the cross-country patterns of risky innovation and growth through the lens of international trade. We use a simple theoretical framework of risky quality upgrading by firms under varying levels of financial development to derive two predictions. First, the mean rate of quality...

How does risk or uncertainty in the productivity of research affect the growth rate of the economy? To answer this question, a model of endogenous technological change is used where sustained growth stems from intentional investments in R&D from profit-maximizing firms. The uncertainty arises...

This review article tries to answer four questions: (i) what are the stylized facts about uncertainty over time; (ii) why does uncertainty vary; (iii) do fluctuations in uncertainty matter; and (iv) did higher uncertainty worsen the Great Recession of 2007-2009? On the first question both macro...

This paper combines the Aiyagari/Huggett–type standard incomplete markets model with the Arrow/Romer approach to growth to analyze feedback effects between growth and inequality, both endogenously determined in equilibrium. We derive conditions on existence/ nonexistence of balanced growth...

In this paper the impacts of income and consumption taxes are analyzed within a model of stochastic endogenous growth with congestion. It is shown that the optimal amount of governmental input diminishes with uncertainty and that the optimal financing depends on the relation between the degrees...

Der vorliegende Beitrag analysiert den Einfluß von aggregierten Produktivitätsschocks auf die intertemporale Entscheidung risikoaverser Agenten. Dabei stehen insbesondere die Auswirkungen auf das langfristige Wachstum der Ökonomie im Vordergrund der Betrachtungen. Es wird gezeigt, daß neben...
