International Climate Policy after Kyoto – Economic Challenges Ahead

Abstract
The signs are increasing that the gain in greenhouse gas emissions since the beginning of the 20th century causes the average global temperature to rise. Limiting the temperature rise to 2°C should at least avoid the worst consequences of global warming. This would require the greenhouse gas emissions to reach their maximum value by no later than 2015 and to be dramatically reduced worldwide from that time until 2050. From the economic perspective, there are a number of important questions: In the first place, how can the initial situation be described in economic categories? Therefore, the emissions should first of all be identified by region and sector and thereupon, the adjustment possibilities are to be outlined. Which costs and which revenues are associated with climate policy? The bandwidth of the estimated damage is between 5% and 20% of global gross domestic product (GDP) annually in the case of unmitigated climate change. These estimates are compared to around 1% of global GDP, which would be spent to stabilize the concentration of greenhouse gases in the atmosphere. How are the global targets to be distributed regionally and sectorally, and which economic instruments are recommended for this purpose? Obviously, tradable permits are preferred. Here, the initial assignment and the nature of the allocation on the one hand and the tradability on the other play a prominent role. What politico-economic conflicts arise and what recommendations can economists give to solve these conflicts goal-oriented? Finally, what is to recommend in terms of political economy in order to remain credible in particular in the sense of an international climate agreement?

The Transition to Post-industrial BMI Values Among US Children

NBER Working Paper No. 13898,
No. 13898,
2008
Abstract
In our opinion, the trend in the BMI values of US children has not been estimated accurately. We use five models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 born 1941-2006 on the basis of all NHES and NHANES data sets. We also use some historical BMI values for comparison. The increase in BMIZ values during the period considered was on average 1.3σ (95% CI: 1.16σ; 1.44σ) among black girls, 0.8σ for black boys, 0.7σ for white boys, and 0.6σ for white girls. This translates into an increase in BMI values of some 5.6, 3.3, 2.4, and 1.5 units respectively. While the increase in BMI values started among the birth cohorts of the 1940s among black females, the rate of increase tended to accelerate among all four groups born in the mid-1950s to early-1960s with the contemporaneous spread of TV viewing. The rate of increase levelled off somewhat thereafter. There is some indication that among black boys and white girls born after c. 1990 adiposity has remained unchanged or perhaps even declined. The affects of the IT revolution of the last two decades of the century is less evident. Some regional evidence leads to the speculation that the spread of automobiles and radios affected the BMI values of boys already in the interwar period. We infer that the incremental weight increases are associated with the labor-saving technological developments of the 20th century which brought about many faceted cultural and nutritional revolutions.

Measurement Matters — Alternative Input Price Proxies for Bank Efficiency Analyses
Michael Koetter
Journal of Financial Services Research,
No. 2,
2006
Abstract
Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But at the same time, most studies are based on cost and/or profit models that assume perfect input markets. Traditional input price proxies therefore contain at least substantial measurement error. We suggest here two alternative input market definitions to approximate exogenous input prices. We have access to Bundesbank data, which allows us to cover virtually all German universal banks between 1993 and 2003. The use of alternative input price proxies leads to mean cost efficiency that is significantly five percentage points lower compared to traditional input prices. Mean profit efficiency is hardly affected. Across models, small cooperative banks located in large western states perform best while large banks and those located in eastern states rank lowest.

A strategy view on knowledge in the MNE – Integrating Subsidiary Roles and Knowledge Flows
Björn Jindra
East-West Journal of Economics and Business,
1 & 2
2005
Abstract
We assume knowledge inflows endogenous to subsidiary roles. Integrating organisational and knowledge-based views we propose a new subsidiary typology based on MNE integration-subsidiary capability. We hypothesise that both dimensions are positively associated with knowledge inflows into the focal subsidiary. This prediction is tested with data for 425 subsidiaries. The key findings were: (a) the extent for knowledge inflows differs significantly across all subsidiary roles; (c) it diminishes in a anti-clockwise direction starting in the high integration-high capability quadrant of the IC taxonomy; thus (b) both MNE integration and subsidiary capability drive knowledge inflows, although, the balance shifts more towards integration.

Evaluationsbericht: Das Internet strategisch richtig nutzen
Albrecht Kauffmann, P. J. J. Welfens, M. Vogelsang
Diskussionsbeiträge des Europäischen Instituts für Internationale Wirtschaftsbeziehungen (EIIW), Universität Potsdam, Nr. 79,

Abstract
Using the internet and internetbased services is now common among medium and large firms in Germany. However, for smaller firms (SMEs) the use of internet application is a new challenge to which they still have to respond – this is crucial for remaining competitive. The project Adapt2 “Using the Internet in an adaquate and strategic way“ looks into the effects of SMEs' basic steps towards the internet. We focus on adequacy of government promotion of SME activities – specifically firms from the sector producing machinery and equipment are analysed. The project was led by ZENIT GmbH, Mülheim a.d. Ruhr; the whole project also involved participation of the European Institute for International Economic Relations (EIIW). As part of a broader evaluation EIIW also conducted surveys – both focussing on firms involved in the project and in other firms from the same sector. It turned out that specific measures of support indeed were helpful for SMEs; obviously, there is additional need for further practical support and research.
