In this paper I study the optimal control path for a (capital or pollution) stock which accumulates time with a lag to its control. It is shown that the optimal control path is non-monotonic and cyclical in general, but it is monotonic if the objective function is additively separable in the...

An analytical framework is developed to study the repercussions between endogenous capital- and labor-saving technical change and population aging. Following an intuition often attributed to Hicks (1932), I ask whether and how population aging aff ects the relative scarcity of factors of...

Empirische Untersuchungen über die Auswirkungen der Transformation im ländlichen Alltagsleben der Ukraine sind nur selten zu finden. Makroökonomische und finanzpolitische Betrachtungen dominieren die Fachliteratur. Daher ist das Bild über die Veränderungen im ländlichen Raum auch noch...

This paper develops a general-equilibrium model of skill-biased technological change that approximates the observed shifts in the shares of wage and non-wage income going to the top decile of U.S. households since 1980. Under realistic assumptions, we find that all agents can benefit from the...

This paper is about “Capital in the Twenty-first Century” by Thomas Piketty. It identifies his central macroeconomic claims and examines them, arguing that the contentions are theoretically and empirically unwarranted.

We characterize the Laffer curves for labor taxation and capital income taxation quantitatively for the US, the EU-14 and individual European countries by comparing the balanced growth paths of a neoclassical growth model featuring ”constant Frisch elasticity” (CFE) preferences. We derive...

This paper presents a new model of endogenous wage and capital dispersion where heterogeneity is driven by entrepreneurial incentives to pay higher wages in order to attract and retain workers. The main contribution of this model is to provide a framework with microeconomic foundations that give...
