Many developing countries around the world apply progressive water tariffs, often structured in the form of discretely increasing block tariffs (IBTs). These tariffs have been criticized in the welfare economic literature due to their perceived inefficiency: many of the prices charged under IBTs...

This note explores the relationship between the price elasticity of demand and the R&D intensity of the product. We introduce the concept of R&D intensity into a standard Dixit-Stiglitz/Krugman-type setting. R&D activity is treated as a fixed cost of production. Within this framework, sectors...

We analyze the properties of progressive water tariffs that are often applied in the sector in the form of discretely increasing block tariffs (IBT). We are particularly interested in water tarification in a poverty context where a subsistence level of water has to be allocated to each...

This paper analyzes a modified yardstick competition mechanism (MYC), where the yardstick employed consists of a tariff basket and total costs. This mechanism has a significant information advantage: the regulator "only" needs to observe total costs and output of all firms. The modified...

Like other data quality dimensions, the concept of accuracy is often adopted to characterise a particular data set. However, its common specification basically refers to statistical properties of estimators, which can hardly be proved by means of a single survey at hand. This ambiguity can be...

In this paper R2-type measures of the explanatory power of multivariate linear and categorical probit models proposed in the literature are reviewed and their deficiencies are discussed. It is argued that a measure of the explanatory power should take into account the components which are...

It is argued that the observed return rates on capital at firm-level have an upward bias if firms are producing with unobserved intangible capital. Using EUKLEED, a comprehensive firm level data base for Germany, this theoretical preposition is proved empirically. Furthermore, making unobserved...

With the 2008 reform of business taxation (Unternehmensteuerreform 2008) a preferential treatment of retained earnings for non-incorporated companies was introduced: Earnings may be retained at a preferential tax rate (29.8%) and will be subjected to supplementary tax (26.4%) when they will be...

Becker and Murphy (1988) constructed, in a well-known paper, a model of rational addiction in which people solve a dynamic optimization problem, choose an optimal timepath of drug consumption and thereby maximize lifetime utility. The model leads to the hypothesis that future consumption is a...

We estimate the elasticity of corporate taxable income with respect to the effective corporate tax rate on the basis of a pseudo-panel constructed from corporate tax return micro data for the period 1998-2001, a period which saw the introduction of a major corporate tax reform in Germany....
