Business cycle models often abstract from persistent household heterogeneity, despite its potentially significant implications for macroeconomic fluctuations and policy. We show empirically that the likelihood of being persistently financially constrained decreases with cognitive skills and increases with overconfidence thereon. Guided by this and other micro evidence, we add persistent heterogeneity ...
This study provides the first absolute income mobility estimates for postwar Germany. Using various micro data sources, we uncover a steep decline in absolute mobility rates from 81 percent to 59 percent for children’s birth cohorts 1962 through 1988. This trend is robust across different ages, family sizes, measurement methods, copulas, and data sources. Across the parental income distribution, we ...
Following yesterday's Bundestag elections, DIW President Marcel Fratzscher commented on the results and the challenges facing the new German government:
Using a large-scale natural experiment in staggered billing dates for energy use in Germany and a unique billing dataset for multi-apartment buildings, this paper shows that the month of billing is a significant determinant of heat energy consumption. A large set of residential buildings demand significantly more heat energy annually, when the bill is issued during off-winter months. The paper finds ...

In this case study, we examine a novel aspect of data collected in a typical probability and a typical nonprobability panel: mobile app data. The data were collected in Great Britain in 2018, using the Innovation Panel of the UK Household Longitudinal Study and the Lightspeed online access panel. Respondents in each panel were invited to participate in a month-long study, reporting all their daily ...
German history over the past 125 years has been turbulent. Marked by two world wars, revolutions and major regime changes, as well as a hyperinflation and three currency reforms, expropriations and territorial divisions, it comprises extreme shocks to study the role of historical events, taxation, asset price changes, portfolio heterogeneity in affecting the wealth distribution in the long run. Combining ...
