The current extensive literature on irreversible investment decisions usually makes the assumption of constant interest rate. In this paper we study the impact of interest rate and revenue variability on the decision to carry out an irreversible investment project. Given the generality of the...

The paper analyses the impacts of occupational choice and entrepreneurial effort on the structure of wage, profit and capital taxation. Entrepreneurial effort is unobservable and therefore not tax-deductible. The optimal profit tax is less than unity even if individual entrepreneurial effort is...

The paper addresses the classical question how to lead the economy from a recession back to full employment in an open economy. In a recession caused by an adverse demand shock, optimal policies crucially depend on whether the income multiplier related to a policy is bigger than unity. This...

Central concerns of research and innovation policies under uncertainty and systemic complexity are market and systemic failures, i.e. both market corrections as well as co-ordination and coherence are essential elements of policy making. Therefore, policy making cannot be based on the notions of...

This paper studies a revenue-neutral green tax reform that substitutes energy for wage taxes in an open economy with unemployment. As long as the labour tax rate exceeds the energy tax rate, such a reform will increase employment, reduce the domestic firms' unit cost of production and hence...

We analyze housing taxation from a political economy perspective. Our aim is to understand why the US tax system favors owner housing with respect to business capital despite the efficiency losses involved. The starting point of our analysis is the observation that housing wealth is much more...

We use the Hartman rotation model to study behavioral and social welfare effects of forest tax progression. The following new results are shown for harvest and timber taxes. First, a tax-revenue neutral increase in the timber tax rate, compensated by a higher tax exemption, will shorten the...

This paper analyzes the socially optimal forest taxation in the rotation framework when the government has a binding tax revenue requirement. In the Faustmann model the optimal design of taxation consists of non-distortionary taxes, such as site productivity tax, site value tax or profit tax. A...

An employer-employee panel is used to study whether the movement of workers across firms is a channel of unintended diffusion of R&D-generated knowledge. Somewhat surprisingly, hiring workers from others’ R&D labs to one’s own does not seem to be a significant spillover channel. Hiring...
