    STRATEGIC TRADE POLICY WITH INTERNATIONALLY OWNED FIRMS (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Bulletin of economic research 47 (1995), S. 0 
    Details
    ISSN: 1467-8586
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Economics
    Notes: The consequences of international firm ownership for strategic trade policy are examined both in a general and in a simple linear model of an international duopoly with two governments using production subsidies as policy instruments. At first sight, the case for strategic trade policy seems to be weakened, because international ownership reduces a government's incentive for rent-shifting. Closer inspection shows, however, that there are ownership structures leading to optimal policies which induce the duopolists to behave more collusively. This tends to resolve the conflict between national and international rationality in a policy game with retaliation and makes strategic trade policy look more attractive.

    Technology and Cost Efficiency in Universal Banking A “Thick Frontier”-Analysis of the German Banking Industry (1998)
    Springer
    Journal of productivity analysis 10 (1998), S. 63-84 
    Details
    ISSN: 1573-0441
    Keywords: Banking ; Translog Cost Function ; Economies of Scale ; Economies of Scope ; Inefficiency
    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract Using 1992 data of 1490 banks covering about 40% of German banking, we specify a multi-product translog cost function and follow the “thick frontier”-approach to control for cost inefficiency when evaluating the technology of banking. Scale economies are found to exist up to a size of about 5 billion DM of total assets, with diseconomies being caused by non-operating costs. There is hardly any evidence of economies of scope. Compared to cost inefficiency external factors play a surprisingly strong role in explaining cost differences between high-cost and low-cost banks. Smaller banks turn out to be more responsive to input prices.

    Mergers Among German Cooperative Banks: A Panel-based Stochastic Frontier Analysis (1999)
    Springer
    Small business economics 13 (1999), S. 273-286 
    Details
    ISSN: 1573-0913
    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract Based on an unbalanced panel of all Bavarian cooperative banks for the years of 1989--97, which includes information on 283 mergers, we analyze motives and cost effects of small-scale mergers in German banking. Estimating a frontier cost function with a time-variable stochastic efficiency term, we show that positive scale and scope effects from a merger arise only if the merged unit closes part of the former branch network. When we compare actual mergers to a simulation of hypothetical mergers, size effects of observed mergers turn out to be slightly more favorable than for all possible mergers. Banks taken over by others are less efficient than the average bank in the same size class, but exhibit, on average, the same efficiency as the acquiring firms. For the post-merger phase, our empirical results provide no evidence for efficiency gains from merging, but point instead to a leveling off of differences among the merging units.

    A note on the time inconsistency of strategic trade policy (1992)
    Springer

    ISSN: 1573-708X

    Source: Springer Online Journal Archives 1860-2000
    Topics: Economics
    Notes: Abstract In a simple three-stage model of an international Cournot duopoly, optimal strategic trade policy is shown to be time inconsistent. If the domestic government first announces a production subsidy, firms then irrevocably commit resources to R&D, and finally play their output game, there is an incentive for the government to revise its ex ante optimal policy once R&D decisions have been made. If private agents anticipate this revision and if the government does not have the power to commit itself to the ex ante optimal policy, a credibility constraint has to be imposed.

    Description / Table of Contents: On the Configuration of the Jaborosalactones, a New Degradation Scheme for WithanolidesThe 14α.17αH.20S-configuration in the Jaborosalactones was demonstrated by the degradation of Jaborosalactone D (4a) to known steroids. A new degradation scheme was used, the crucial steps of which were the hydrogenation of 6 to give 7, the hydrogenolysis of 9, and the ether cleavage in 15.
    Notes: Die 14α.17αH.20S-Konfiguration der Jaborosalactone wurde durch Verknüpfung von Jaborosalacton D (4a) mit bekannten Steroiden bewiesen. Es wurde ein neuer Withanolid-Abbau entwickelt, dessen entscheidende Schritte die Reduktion von 6 zu 7, die Hydrogenolyse von 9 und die Ätheröffnung bei 15 sind.

On the C-N-coupling Step in the Formation of Semidine DerivativesTetraarylhydrazines rearrange on heating to isomeric o- and (or) p-semidines. It was found, that these semidines are not formed form the intermediate diarylaminyl radicals via a radical substitution process.
    Notes: Es wurde nachgewiesen, daß die bei der Thermolyse von Tetraarylhydrazinen gebildeten isomeren o- und (oder) p-Semidine aus den intermediär auftretenden Diarylaminylen nicht durch homolytische aromatische Substitution entstehen.

    Description / Table of Contents: The Hydrogenolysis of Some 6β-Acetoxy- and 6β-Hydroxy-Steroid Δ4-OlefinsThe hydrogenolysis of the compounds 1, 4, 8, 9, and 10 with palladium as catalyst furnished a mixture of the corresponding Δ4- and Δ5-olefins. The results can be rationalized by assuming the formation of an intermediate π-allyl complex which is reduced to form the Δ4- and the Δ5-olefin. Hydrogenation of 8 with platinum in acetic acid gave the two 5β-steroids 6 and 7.
    Notes: Die Hydrogenolyse der Verbindungen 1, 4, 8, 9 und 10 über einem Palladium-Katalysator lieferte ein Gemisch der entsprechenden Δ4- und Δ5-Olefine. Die Ergebnisse können so interpretiert werden, daß intermediär ein π-Allyl-Komplex auftritt, der zum Δ4- und zum Δ5-Olefin reduziert wird. Über Platin in Eisessig ergab 8 die beiden 5β-Steroide 6 und 7.

    Description / Table of Contents: The Thermal Decomposition of Tetraphenylhydrazine. A Contribution to the Problem of the Non-catalysed Benzidine RearrangementThe thermal decomposition of tetraphenylhydrazine (4) affords besides diphenylamine only the o- and the p-semidine 6a and 7a, respectively, and compounds derived from them. None of the other possible rearrangement products, which were synthesized independently, is formed. The results are compared with previous work on the thermal benzidine rearrangement and its mechanism.
    Notes: Bei der thermischen Zersetzung des Tetraphenylhydrazins (4) entstehen neben Diphenylamin nur das o- und das p-Semidin 6a und 7a, sowie Folgeprodukte davon. Die Bildung der anderen denkbaren Umlagerungsprodukte von 4, die auf unabhängigen Wegen synthetisiert wurden, kann ausgeschlossen werden. Die Ergebnisse werden im Vergleich zu früheren Arbeiten über die thermische Benzidin-Umlagerung und Vorstellungen über ihren Mechanismus diskutiert.
