In this study we compare the traditional OLS approach applied to the log-linear form of the gravity model with the Poisson Quasi Maximum Likelihood (PQML) estimation procedure applied to the non-linear multiplicative specification of the gravity model. We use the trade flows for all products, for all manufacturing products as well as for manufacturing products broken down by three-digit ISIC Rev.2 ...

This paper expands Shleifer's (Rand J Econ 16:319-327, 1985) theory of yardstick competition and develops 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, prices and output of all firms. The MYC mechanism can ensure a socially ...

It widens the conventional focus on technological innovations to encompass organisational and behavioural innovations. The investigation builds on five empirical studies of recent developments ...

Does tax policy affect entrepreneurial choice? We use two tax reforms in Germany as "natural experiments". These reforms reduced the marginal income tax rate for entrepreneurs with income above a certain threshold, with the exception of freelance professionals. The two conditions for belonging to the treatment group allow us to apply a "difference-in-difference-in-difference" identification strategy ...

We model competition between two unregulated mobile phone companies with price-elastic demand and less than full market coverage. We also assume that there is a regulated full-coverage fixed network. In order to induce stronger competition, mobile companies could have an incentive to raise their reciprocal mobile-to-mobile access charges above the marginal costs of termination. Stronger competition ...

When potential income tax reforms are debated, the suspected impact on entrepreneurship is often used as an argument in favour of or against a certain policy. Quantitative ex-ante evaluations of the effect of certain tax reform options on entrepreneurship are very rare, however. This paper estimates the ex-ante effects of the German tax reform 2000 and of two hypothetical flat-rate tax scenarios on ...

In Deutschland stehen für Fragen der empirischen Bildungsforschung bislang überwiegend Querschnittserhebungen zur Verfügung, die ergänzt werden durch länderspezifische bzw. gruppenspezifische Längsschnitterhebungen. Zudem sind diese in der Regel auf einzelne Übergänge im Bildungssystem fokussiert. Die Herausforderung einer lebensverlaufstheoretischen Bildungsforschung liegt jedoch in der Analyse von ...

We analyze the distribution of market income in Germany in the period 1992 to 2003 on the basis of an integrated dataset that encompasses the whole spectrum of the population, from the very poor to the very rich. We find a modest increase of the Gini coefficient, a substantial drop of median income and a remarkable growth of the income share accruing to the economic elite, which we define as the richest ...

This paper studies the determinants of the unusually high and volatile price differential between common (voting) shares and preferred (nonvoting) shares in Russia's emerging stock market. It focuses on three potential explanations for the price spread between these two classes of stock: the control contest model of the voting premium, the inferior liquidity of preferred shares, and the risk of expropriation ...

In Europe, two market designs are discussed for electricity trade and transmission. We argue that their performance in the presence of market power can be represented by two models from the literature. In contrast to examples for simple two-node networks, we show that in more complex networks a general ranking of both designs is not possible. Hence, computational models are required to evaluate the ...
