We develop an endogenous growth model to quantify how permanent structural policy changes that enhance the fiscal policy mix, markets' functioning, and public institutions' quality affect long-term growth and welfare. The reforms include increased public investment, reduced market power through...

This paper explores the long-run impacts of tax policy in a two-country model of endogenous growth with variable labor supply. We focus on international spillover effects of tax reforms under alternative trade structures. It is shown that if the instantaneous utility function of the...

Empirical evidence suggests that positive externalities from R&D exceed negative ones. According to conventional wisdom, this calls for R&D subsidies. This paper develops a quality-ladder growth model with overlapping generations which evaluates the positive and normative implications of R&D...

We reexamine the properties of optimal fiscal policy and their implications for implementable capital accumulation. The setup is a standard endogenous growth model with public production services, augmented by elastic labor supply. We show that, when a benevolent government chooses a distorting...

Since the financial crisis in 2008, slow growth has riddled Europe and the Covid-19 pandemic is amplifying the challenge. Promoting economic growth and transforming to a more knowledge-based industrial structure will be high on the agenda for the coming decades. We study how more and better...

We propose a theoretical framework to reconcile episodes of V-shaped and L-shaped recovery, encompassing the behaviour of the U.S. economy before and after the Great Recession. In a DSGE model with endogenous growth, negative demand shocks destroy productive capacity, moving GDP to a lower...

Climate mitigation policy should be imposed over a long period, and spur development of new technologies in order to make stabilization of green house gas concentrations economically feasible. The government may announce current and future policy packages that stimulate current R&D in...

Sustainability and efficiency are potentially conflicting social objectives in natural resource management. We propose a market mechanism to allocate use rights over a stochastic resource to private managers. The mechanism endogenously determines the maximal tenure length guaranteeing that the...

We study the effects of time-using rent-seeking activities on the macroeconomic allocation and the economic growth rate. We formulate a highly stylized three-sector general equilibrium model with overlapping generations of individuals. The production side features one sector producing the...

This paper shows that dynamic inefficiency can occur in dynamic general equilibrium models with fully optimizing, infinitely-lived households even in a situation with underinvestment. We identify necessary conditions for such a possibility and illustrate it in a standard R&D-based growth model....
