The study of economic growth is concerned with long-run changes, and therefore, historical data should be especially influential in informing the development of new theories. In this review, we draw on the recent literature to highlight areas in which study of history has played a particularly prominent role in improving our understanding of growth dynamics. Research at the intersection of historical data, theory, and empirics has the potential to reframe how we think about economic growth in much the same way that historical perspectives helped to shape the first generation of endogenous growth theories.

Die globale Bankenkrise der Jahre 2008/2009 hatte weltweit signifikant negative Auswirkungen auf die Realwirtschaft, und in vielen Ländern fiel die folgende wirtschaftliche Erholung deutlich langsamer aus als in vorherigen Rezessionen. In den Monaten nach der Insolvenz der amerikanischen Investmentbank Lehman Brothers reduzierten Banken ihre Kreditvergabe an Unternehmen, was zu einem Anstieg der Arbeitslosigkeit, einem Rückgang an Investitionen und einer Verringerung der Produktivität führte. Während diese kurzfristigen Effekte in der bisherigen Forschung gut dokumentiert sind, sind die langfristigen Auswirkungen von Bankenkrisen bisher weit weniger gut verstanden. Zwei aktuelle Studien unter IWH-Beteiligung zeigen, dass Bankenkrisen generell negative langfristige Effekte auf das Wachstum von Firmen haben, dass die Rettung von schwachen Banken während der Krise mit Produktivitätsverlusten in späteren Jahren einhergeht, und dass diese negativen langfristigen Effekte durch die Existenz inflexibler Löhne verstärkt werden.

Reserve requirements, as a tool of macroprudential policy, have been increasingly employed since the outbreak of the great financial crisis. We conduct an analysis of the effect of reserve requirements in tranquil and crisis times on long-run growth rates of GDP per capita and credit (%GDP) making use of Bayesian model averaging methods. Regulation has on average a negative effect on GDP in tranquil times, which is only partly offset by a positive (but not robust effect) in crisis times. Credit over GDP is positively affected by higher requirements in the longer run.

Does private equity (PE) contribute to financial fragility during economic crises? The proliferation of poorly structured transactions during booms may increase the vulnerability of the economy to downturns. During the 2008 crisis, PE-backed companies decreased investments less than did their peers and experienced greater equity and debt inflows, higher asset growth, and increased market share. These effects are especially strong among financially constrained companies and those whose PE investors had more resources at the crisis onset. In a survey, PE firms report being active investors during the crisis and spending more time working with their portfolio companies.
