Environmental externalities call for the use of environmental taxes to get prices right and thereby reduce environmental pressures. To date, however, the Spanish government makes only limited use of environmental taxes. One major reason for the policy reluctance are concerns on the regressive...

Using administrative employer-employee data from Germany, we investigate the relationship between wages and past and present labor market conditions. Furthermore, we revisit recent findings of greater wage cyclicality of new hires. Overall, we find strong evidence for history dependent wages,...

Renewable energy (RE) policies are widely used to decarbonize power generation and implemented at various governance levels. We use an analytically tractable two-level model to study the effects of overlapping RE policies from the federal and state governments. We find that there are contrasting...

This paper studies market segmentation that arises from the introduction of a price ceiling in the market for rental housing. When part of the market faces rent control, theory predicts an increase of free-market rents, a consequence of misallocation of households to housing units. We study a...

Sovereigns' public capital influences sovereign debt crises and resolution. We compile a dataset on public expenditure composition around restructurings with private external creditors. We show that during restructurings, public investment experiences severe decline and slow recovery, differs...

This work seeks to answer the "population question," i.e. the effect of population growth on production per capita. This question has lingered in economic thought for centuries and to this day two general lines of thought can be identified, which might be marked as the "optimist" and the...

In spite of two centuries of extensive debate, a consistent framework of the classical theory of population on which economists can universally agree has not been established. This means that either the theory lacks consistency or it has been misunderstood in important ways. This paper attempts...

Machine learning is increasingly applied to time series data, as it constitutes an attractive alternative to forecasts based on traditional time series models. For independent and identically distributed observations, cross-validation is the prevalent scheme for estimating out-of-sample...

In this paper, we revisit the empirical observation that prices rise like rockets when input costs increase but fall like feathers when input costs decrease. The analysis draws on a novel dataset that include daily retail prices of gasoline and diesel from virtually all fuel stations in Germany...

Nach den Berechnungen der Autoren mit dem vom Stabilitätsrat verwendeten Aggregierten Quotierungsverfahren (AQV) konnten im Jahr 2017 schon 14 Bundesländer strukturell mindestens ausgeglichene Haushalte erzielen. In der aktuellen Niedrigzinsphase überzeichnet das AQV jedoch die erzielten...
