Purpose: The authors observed few sectors with many connections and many sectors with few connections, “in the Brazilian input-output network,” which meant that sectoral idiosyncratic shocks may lead to aggregate fluctuations. Design/methodology/approach: The authors considered the...

Casey Mulligan suggested in The Economists' Voice that this recession was caused by "something [that] made real wages high and employment low." This coincides with his own view of the causes of the Great Depression. The similarity inevitably brings back General-Theory-Keynes, according to Da...

Die Rolle der Devisenmarktintervention im Chaotischen Dornbusch-Modell Modelle von De Grauwe und Dewachter (1992) und De Grauwe, Dewachter und Embrechts (1993), in denen der Wechselkurs im Rahmen des Dornbusch-Modells chaotischen Tendenzen unterliegen kann, zeigen, daß starke...

Purpose: A recent population-wide study for Germany, where credit lines on current accounts are available to 80 percent of the population, finds that overdraft debt is more likely for people who give intuitive but incorrect answers on a cognitive reflection test. This suggests that those...

I argue that it is microeconomics that needs foundations, not macroeconomics. Preferences need to be built on biology, and, in particular, on neuroscience. In contrast, macroeconomics could benefit from rationalizations of aggregate economic phenomena by non-equilibrium statistical physics. --

We investigate how loss aversion and entitlement influence lying. We conducted an online experiment with a cheating task in which participants drew and reported a number. Participants are instructed to report their draw honestly, but they may cheat by saying a different number in order to earn a...

If stock markets are complex, monetary policy and even financial regulation may be useless to prevent bubbles and crashes. Here, we suggest the use of robot traders as an anti-bubble decoy. To make our case, we put forward a new stochastic cellular automata model that generates an emergent stock...

Because sports are stylized combat, sports may follow power laws similar to those found for wars, individual clashes, and acts of terrorism. We show this fact for football (soccer) by adjusting power laws that show a close relationship between rank and points won by the clubs participating in...
