The author identifies three principal economic phenomena, which are explained: long run productivity growth as the central driver of increasing economic activity, short-term and long-term debt cycles. The latter two are explained to some detailed with reference to money creation, central banking and long term crisis tendencies. With regards to the long run debt cycle, which leads into deleveraging and recession, some policy measures which can smoothen the crisis are discussed.

In this keynote speech, Roger Backhouse gives a historical overview of theories on secular stagnation: how it evolved from a description of the economic situation, especially in the U.S. of the 1930s to an analytical tool and then lost importance until its current revival. Backhouse touches upon the contributions of J. A. Hobson, Alvin Hansen, Evsey Domar and Paul Samuelson.

Carsten Dreher starts with a historical perspective on the development of evolutionary economics by mentioning the difficulties of neoclassical economics to explain economic growth and by referring to the work of Joseph Schumpeter. Then some concepts such as business cycles, path dependencies are shortly explained. Dreher continues by introducing two different approaches in evolutionary economics, a micro centred approach that is associated with Nelson and Winter's work and a macro institutional and historical approach that has been pursued amongst others by Chris Freeman. Lastly the policy implications of treating economies as innovation systems are discussed and a summary of the differences of neoclassical and evolutionary economics is provided.

In diesem Workshop zeigt Christian Proaño die Kritik an der Neuen Neoklassischen Synthese aus Sicht der Behavioral Macroeconomics. Für Fortgeschrittene gibt er einen Einblick in Behavioral Macroeconomics und zeigt Modelle mit heterogenen Erwartungen (De Grauwe 2012), den Aggregate Sentiments Approach (Franke 2012) sowie den Learning Aproach (nach Evans, Honkapohja 2001). Kritiker könnten der Behavioral Macroeconomics Forschung vorwerfen, dass sie im Grunde Neoklassische Konzepte repariert, das wissenschaftstheoretische Fundament aber nie verlässt und sich damit selbst begrenzt.

The world is coping with a global disaster, as the new Coronavirus takes a toll on many lost lives and a severe impact on economic activity. To provide a long-run perspective, this column documents the international response to a variety of disasters since 1790. Based on a new comprehensive database on loans extended by governments and central banks, official (sovereign-to-sovereign) international lending is much larger than generally known. Official lending spikes in times of global turmoil, such as wars, financial crises or natural disasters. Indeed, in these periods, official capital flows have repeatedly surpassed total private capital flows in the past two centuries. Wars, in particular, were accompanied by large surges in the volume of official cross-border lending.
