Independent regulatory authorities are a basic prerequisite for a successful liberalization process. However, contrary to what is expected, both graphical analyses and OLS regressions for a small sample of electricity and gas regulators operating in 16 European countries reveal a negative...

Inconsistent voting behavior is defined as a changing preference on the preferred interest rate voiced in the policy go-around relative to the interest rate preference cast in the formal...

This paper provides a multivariate score-type test to distinguish between true and spurious long memory. The test is based on the weighted sum of the partial derivatives of the multivariate local Whittle likelihood function. This approach takes phase shifts in the multivariate spectrum into...

The transportation processes for patients, personnel, and material in large and complex maximum-care hospitals with many departments can consume significant resources and thus induce substantial logistics costs. These costs are largely determined by the allocation of the different departments...

This paper presents results from a randomized evaluation of a home visiting program for disadvantaged first-time mothers and their families implemented in three German federal states. I analysis the impact of the intervention on maternal employment, school attendance, child care use, fertility,...
