Is the Spanish economy positioned at its optimal progressivity level in personal income tax? This article quantifies the aggregate, distributional, and welfare consequences of moving toward such an optimal level. A heterogeneous households general equilibrium model featuring both life cycle and...

With capital-skill complementarity, the secular decline in the price of capital equipment due to equipment-specific technological progress (ESTP) keeps pushing up the demand for skilled relative to unskilled labor and raising the skill premium. This paper quantitatively characterizes the...

Fertility rates are declining in many countries. But are fertility rates inefficiently low? This paper addresses this question by exploring the efficiency properties of equilibria in an overlapping generations setting with endogenous fertility and dynastic parental altruism, using a particular...

This paper investigates the relationship between economic growth in Poland and selected elements of fiscal policy and private spending on education. We use the Mankiw-Romer-Weil model, augmented with learning-by-doing and spillover-effects and with concepts from the literature on optimal fiscal...

This paper investigates the relationship between economic growth in Poland and four types of taxes and human capital investment. We primarily rely on an exogenous growth model that merges the Mankiw-Romer-Weil model, augmented with learning-by-doing and spillover-effects, with selected elements...

Debt Overhang is a controversial issue in the eurozone countries and is considered as one of the factors which created the current economic crisis. How to deal with sovereign debt has been debated both at the theoretical and policy making level. This paper looks at the Greek debt and four...

Large and growing levels of public debt in the United States, United Kingdom, Japan and the Euro Area raise new interest in the cross-country effects of a large open economy's deficits. The authors consider a dynamic optimising model with costly tax collection and exogenously given public...

Based on a quantitative, heterogeneous agent general equilibrium model, we compute the optimal tax rates for labor and capital incomes for the Korean economy. According to our model, a more progressive income tax schedule along with a higher capital tax rate can increase average welfare by as...

Climate policies, including removing fossil fuel subsidies or imposing carbon prices, can be designed in a way that is both efficient in addressing climate change and results in a fair distribution of the associated costs.
