Levels of and Changes in Life Satisfaction Predict Mortality Hazards: Disentangling the Role of Physical Health, Perceived Control, and Social Orientation

It is well documented that well-being typically evinces precipitous decrements at the end of life. However, research has primarily taken a postdictive approach by knowing the outcome (date of death) and aligning, in retrospect, how well-being has changed for people with documented death events.

Disappointed Hopes of Upward Mobility? A Study on Income Development in Germany 1995-2015

Similar to many other OECD countries, income inequality in Germany has increased over the past decades.

Local and Spatial Cointegration in the Wage Curve – a Spatial Panel Analysis for German Regions

The wage curve introduced by Blanchflower and Oswald (1990, 1994b) postulates a negative correlation between wages and unemployment. Empirical studies use different channels for a theoretical underpinning the relationship. Panel data models mostly draw on bargaining power or the efficiency wage hypothesis. Spatial econometric approaches can be rationalized by monopsonistic competition. However, the ...
