This paper analyses the duration of child poverty in Germany. In our sample, we observe the entire income history from the individuals’ birth to their coming of age at age 18.Therefore we are able to analyze dynamics in and out of poverty for the entire population of children, whether they...

Sample selection models, variants of which are the Heckman and Heckit models, are increasingly used by political scientists to accommodate data in which censoring of the dependent variable raises concerns of sample selectivity bias. Beyond demonstrating several pitfalls in the calculation of...

This paper examines the relative savings position of migrant households in West Germany, paying particular attention to differences between temporary and permanent migrants.Our findings reveal significant differences in the savings rates between foreign-born and German-born individuals. These...

The classical Heckman (1976, 1979) selection correction estimator (heckit) is misspecified and inconsistent if an interaction of the outcome variable and an explanatory variable matters for selection. To address this specification problem, a full information maximum likelihood estimator and a...

In this paper, a decomposition method for Tobit-models is derived, which allows the differences in a censored outcome variable between two groups to be decomposed into a part that is explained by differences in observed characteristics and a part attributable to differences in the estimated...

The behavioural response with respect to actuarial adjustments in the German public pension system is analysed. The introduction of actuarial adjustments serves as a source of exogenous variation to estimate discrete time transition rates into retirement. The analysis is conducted on...

The confluence of factors driving urban growth is highly complex, resulting from a combination of ecological and social determinants that co-evolve over time and space. Identifying these factors and quantifying their impact necessitates models that capture both why urbanization happens as well...

By the mid-19th century, following the Prussian mining reform, German miners‘ combined mutual health and pension funds took on the characteristics of social insurance and underwent a concentration process driven by mergers, liquidations, and unequal internal growth. This paper investigates the...

This study examines the determinants of urbanized area across a 10,000-mile square swath in central North Carolina, an area undergoing extensive conversion of forest and agricultural land.We model the temporal and spatial dimensions of these landscape changes using a database that links five...

This paper shows how revealed preference relations, observed under general budget sets, can be extended using closure operators which impose certain assumptions on preferences. Common extensions are based on the assumption that preferences are convex and/or monotonic, but we also consider...
