The Paper examines real and nominal wage rigidities. We estimate a switching regime model, in which the observed distribution of individual wage changes, computed from West German register data for 1976-97, is generated by simultaneous processes of real, nominal or no wage rigidity, and...

Based on a large employer-employee matched dataset, the Paper investigates the effects of variable enforcement of German dismissal protection legislation on the employment dynamics in small establishments. Specifically, using a difference-in-differences approach, we study the effect of changes...

High-temperature PCM is a key component for storing latent heat. This is necessary for efficient energy storage in connection with the two-phase heat transfer fluid water/steam. Due to the low thermal conductivity of the nitrate salts used for high-temperature PCM storage, it is necessary to...

For sensible thermal energy storage (TES) in liquids in the temperature range from 250°C to 550°C, a mixture of 60wt% sodium nitrate (NaNO3) and 40wt% potassium nitrate (KNO3), known as Solar Salt, is commonly utilized. At the time of writing, TES technology for concentrating solar power is...

Deutschland befindet sich in einem harten internationalen Wettbewerb um qualifizierte Arbeitskräfte. Dabei steht der aktuelle Fachkräftemangel nur scheinbar im Gegensatz zu einer anhaltend hohen Arbeitslosigkeit von Geringqualifizierten. Gewichtige demographische Argumente sprechen für eine...
