This paper addresses the lack of connection between theory and empirics in most export diversification - economic development studies. We provide a Ricardian-based theoretical explanation of countries' relative export variety as a function of the level of technology and country size assessed...

The paper presents the dynamics of trade diversity with respect to stages of development in the European context. The analysis focuses on EU27 countries observed across the years 1988-2010 and compared to a sample of 136 international economies at all levels of income per capita. We use product...

This paper presents empirical evidence on the diversification process concerning Polish exports (1994-2010), compared to European and global samples of countries. It analyzes both the commodity structure of Polish trade and the geographical diversification of Poland's trading partners. The...

This paper contributes to trade diversification literature by comparing changes in relative (i.e. assessed in comparison with world patterns) heterogeneity of import and export structures in the process of economic development. In particular, by focusing on the diversification of imports, we add...

This paper evaluates the temporary VAT reduction introduced by the German government over the third and fourth quarter of 2020 as most controversial part of the COVID-19 stimulus package. Critics argue that VAT reductions are ineffective because of limited pass-through of temporary measures to...

This paper evaluates the temporary VAT reduction introduced by the German government over the 3Q2020:4Q2020 as a controversial part of the COVID-19 stimulus package. Critics argue that VAT reductions are ineffective because of limited pass-through to consumer prices and during lockdown....

This paper studies how investment tax incentives stimulate output in an estimated medium-scale dynamic stochastic general equilibrium model. We find that the horizon following a positive shock to investment tax incentives is crucial. The shock is highly expansionary in the long run, with the...

The system of capital taxation consists of two instruments, namely a tax on profits and a depreciation allowance on investment. We will show in this paper that by acting on both instruments simultaneously it is possible to achieve both a growth and a fiscal net revenue target even in cases when...

This paper studies how investment tax incentives stimulate output in a medium-scale DSGE model, which allows for a variety of fiscal financing mechanisms. We find that the horizon following a positive shock in investment tax incentives is crucial. The shock is highly expansionary in the long...
