We investigate bunching at personal tax thresholds over a 40-year period. At kinks, where the marginal tax rate rises, we find bunching among company owner-managers and the self-employed, but not those with only employment income. Notches, where the average rate rises, provide compelling...

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,...

Der Mittelstandsbauch führt bei geringen und mittleren Einkommen zu einem schnell steigenden Grenzsteuersatz. Deshalb ist die Beseitigung des Mittelstandsbauchs im steuerpolitischen Diskurs ein bedeutendes Thema. Um diese Debatte mit Fakten zu unterstützen, hat das ifo Institut mögliche...

I explore labor supply responses to an unusually large and salient notch generated by the “Mini-Job” program in Germany. Using administrative data, I document three findings. First, despite the unusually large magnitude of incentives, earnings elasticities are modest, even after accounting...

There is a rising share of individuals spending at least some part of their working life abroad and acquiring pension rights. While the portability of pensions and other social benefits has received some analytical attention over the recent decade there is currently limited analytical guidance...
