Using time-series cross-section data from the manufacturing sector of the 11West German 'Bundesl ¨ander' (Federal States) from 1970 to 1996, I examine the impact of public capital on private production. My econometric analysis explicitly takes into account four of the most frequent specification issues in the context of time-series cross-section data analysis: serial correlation, groupwise heteroscedasticity, ...

Using firm-level panel data from the German cost structure survey over the period 1992 to 2000, our empirical analysis shows that firms that increased material inputs relative to internal labor costs performed better in terms of gross operating surplus than other firms. However, firms that increased external services relative to internal labor costs, thus outsourcing service functions previously provided ...

We present a model of optimal government policy when policy choices may exacerbate socio-political instability (SPI). We show that optimal policy that takes into account SPI transforms a standard concave growth model into a model with both a poverty trap and endogenous growth. The resulting equilibrium dynamics inherit the properties of government policies and need not be monotone. Indeed, for a broad ...

This paper is an attempt to provide evidence on two questions: Why do companies sponsor art events, and where exactly does the money go? We analyse data collected on the revenue structure of cultural institutions in Berlin and Hamburg. This data set not only tells us where the money goes, it also allows us to draw conclusions with respect to donors' motives. We regress sponsorships received on the ...

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 significant explanatory variable for present consumption. This paper briefly surveys the empirical studies ...

DIW Discussion Papers 300 / 2002
A new method for constructing R&D capital stocks is proposed. Following Schumpeter, the development of R&D capital stocks is modelled as a process of creative destruction. Newly generated knowledge is assumed not only to add to the existing R&D capital stocks but also, by displacing old knowledge, to destroy part of that capital. This is in stark contrast to the perpetual inventory method, which postulates ...

This paper investigates the strategic value of the managerial incentive scheme in affecting firms' incentive in R&D investment and their product market activities. Firstly, we find that in Cournot-quantity competition, owners strategically assign a non-profitmaximization objective to their managers. Consequently, managers in a delegation game invest more in cost-reducing R&D, and have higher output, ...

Empirical work on price-cost margins often treats costs as exogenous. Allowing for endogenous costs when estimating price-cost margins is the topic of this paper. Methodologically, the endogenous cost model we propose leads to an additional equation that allows for the simultaneity in price setting in the product and the input market (labor in our case). In other words, the usual two-equation set-up ...

There are various reasons why humans may want to reduce their consumption of meat and other animal products. In the following, we lay out important stylized facts about individual meat consumption, and then discuss the challenges and puzzles surrounding effective behavior change toward more sustainable, plant-based diets.

Es gibt verschiedene Gründe dafür, den Konsum von Fleisch und anderen tierischen Produkten zu reduzieren. In diesem Beitrag stellen wir wichtige Fakten zum Fleischkonsum vor und diskutieren dann mögliche Wege und Herausforderungen in Bezug auf eine effektive Verhaltensänderung hin zu einer nachhaltigeren, weniger tierbasierten Ernährung.
