An Iterative Process for International Negotiations on Acid Rain in Northern Europe Using a General Convex Formulation

This paper proposes a game theoretical approach of internationalnegotiations on transboundary pollution. This approach is distinguished bya discrete time formulation and by a suitable formulation of the localinformation assumption on cost and damage functions: at each stage of thenegotiation, the parties assign the best possible cooperative state, giventhe available information, as an objective for the next stage. It is shownthat the resulting sequences of states converges from a non-cooperativesituation to an international optimum in a finite number of stages.Furthermore, a financial transfer structure is also presented that makesthe desired sequence of states individually rational and stategically stable.The concepts are applied in a numerical simulation of the SO₂transboundary pollution problem related to acid rain in Northern Europe.     

第五方物流的内涵及其研究进展

自21世纪初美国摩根斯坦利公司首次提出第五方物流概念并描画了第一方至第五方的物流金字塔图谱以来,第五方物流作为不拥有物流实物资产,却借助电子商务、网络以及信息技术对整个供应链进行整体协调和物流运作的新型供应链物流解决方案,得到了学界和业界的认同。国内外对基于信息服务的第五方物流的研究,在概念内涵、发展模式、作用前景、物流信息平台的构建和实现等方面取得了一定进展。     

Equity market and foreign capital

Abstract .  I present a model that demonstrates that the market mechanism is not always effective in stabilizing an open equity market. Foreign capital inflows create multiple equilibria in the equity market, which may simultaneously trigger a currency crisis as well as an equity market crash even if the equity market is well developed.     

Estimates of average marginal tax rates on factor incomes in Japan

In this paper, we estimate average marginal tax rates on factor incomes in Japan from 1963 to 2007. We adapt the method of D.H. Joines [Estimates of effective marginal tax rates on factor incomes. J. Bus. 54 (2), 191-226.] to the Japanese tax and social security system. Average marginal tax rates on labor incomes without social security premiums range from 14% to 21%, whereas the rates on incomes with social security have increased from 21% to 33%. Tax rates on capital incomes have fluctuated between 35% and 58%. We also compare our estimates with average tax rates and the wedges from business cycle accounting.

International Cooperation Behind the Veil of Uncertainty – The Case of Transboundary Acidification

The complexities of international environmental problems are only poorly understood. Hence, decision makers have to negotiate about abatement measures even though they do not know the 'true' model of the ecological system and have only a rough idea about the costs and benefits of their action. It will be analysed to what extent this kind of 'model uncertainty' – where players do not only have incomplete information about the payoff functions of the other players, but also about their own payoff function – affects the prospects of international cooperation. Using a simple game-theoretic model, it is shown how countries can use the veil of uncertainty to hide their distributional interests. The arguments are based on a deviation from the common prior assumption, which seems particularly questionable in a setting comprising various countries with different cultural and scientific backgrounds. Finally the model will prove useful to quantitatively and qualitatively illustrate the central role of model uncertainty in the negotiations of the first Sulphur Protocol signed to combat transboundary acidification.     

Non‐Parametric Modelling of CO2 Emission Quota

Dutch glasshouse firms are facing the introduction of a system of tradable CO₂ emission quotas. This paper employs a non‐parametric method for modelling tradable CO₂ emissions of Dutch glasshouse firms. The method is capable of generating shifts in CO₂ emissions across the sample of firms. Moreover, changes in volumes of outputs produced and inputs used are computed. Results show that firms using a conventional heating technology will be net purchasers of CO₂ emissions, whereas firms using more advanced heating technologies will sell part of their emission quota.

Sales recruiting—A major area of underinvestment

How does a firm decide whether the amount now being spent to generate sales force applicants is too much, not enough, or about right? This question can be answered by using information routinely generated by corporate activities and a relatively straight forward decision theory technique. To illustrate that technique, an analysis was conducted for a hypothetical but by no means atypical firm. The results suggest that many corporations could appreciably increase their overall profitability by spending more on sales force recruitment and selection.
