Empirical studies analysing German import demand functions traditionally report implausibly high income and relative low price elasticities. Furthermore, estimation results strongly depend on the observation period. Minor variations in the estimation period typically lead to insignificant price...

We apply a quadratic expenditure system to estimate price and expenditure elasticities of residential energy demand (electricity and heating) in Germany. Using official expenditure data from 1993 to 2008, we estimate an expenditure elasticity for electricity of 0.3988 and of 0.4055 for space...

Considerable empirical research exists on donations in the US and their determinants, including estimations of the income and price elasticity of giving. By contrast, less is known about the determinants of countries with an extensive welfare state. We address this deficiency by studying the...
