On 1 July 2020, value added tax (VAT) rates were reduced in Germany to fight the economic consequences of the Corona pandemic. The VAT rate reduction is temporary as rates will return to their previous level on 1 January 2021. We study the effects of the temporary VAT rate cut on German...

This paper is the first to provide evidence of efficient taxation of groups with heterogeneous levels of 'tax morale'. We set up an optimal income tax model where high tax morale implies a high subjective cost of evading taxes. The model predicts that 'nice guys finish last': groups with higher...

We examine how trade openness influences income inequality within countries. The sample includes 139 countries over the period 1970-2014. We employ predicted openness as instrument to deal with the endogeneity of trade openness. The effect of trade openness on income inequality differs across...

Die Initiative Neue Soziale Marktwirtschaft (INSM) hat das ifo Institut mit der Erstellung einer Studie zum sogenannten Mittelstandsbauch im deutschen Einkommensteuertarif beauftragt. Der Mittelstandsbauch führt bei geringen und mittleren Einkommen zu einem schnell steigenden Grenzsteuersatz,...

Die Studie untersucht vier Reformoptionen, die zu einer Entlastung geringer und mittlerer Einkommen bei gleichzeitig moderater Belastung höherer Einkommen führen. Der Solidaritätszuschlag wird abgeschafft. Der Grundfreibetrag und der Eingangssteuersatz bleiben in allen Varianten unverändert....

Because of endogeneity problems very few studies have been able to identify the incidence of corporate taxes on wages. We circumvent these problems by using an 11-year panel of data on 11,441 German municipalities' tax rates, 8 percent of which change each year, linked to administrative matched...

The success of the flat rate tax in Eastern Europe suggests that this concept could also be a model for the welfare states of Western Europe. The present paper uses a simulation model to analyse the effects of revenue neutral flat rate tax reforms on equity and efficiency for the case of...

This paper estimates the incidence of corporate taxes on wages using a 20-year panel of German municipalities. Administrative linked employer-employee data allows estimating heterogeneous worker and firm effects. We set up a general theoretical framework showing that corporate taxes can have a...
