Before 2004 South Africa was the dominant steam coal exporter to the European market. However a new market situation with rising global demand and prices makes room for a new entrant: Russia. The hypothesis investigated in this paper is that the three incumbent dominant firms located in South...

The study is an endeavor to test the validity of convergence hypothesis in Indian sugar Industry. For inferential purpose, data for 12 major sugar-producing states over the period 1974/75 to 2004/05 has been used. The technical efficiency and scale efficiency scores have been computed using the...

Nuclear is considered as a valuable option for the decarbonization of the power generation, as it is a no-carbon, yet commercially consolidated technology. However, its real prospects are uncertain: if some countries, especially in the non-OECD area, have been extensively investing in nuclear,...

The payoff of many credit derivatives depends on the level of credit spreads. Inparticular, credit derivatives with a leverage component are subject to gap risk, a riskassociated with the occurrence of jumps in the underlying credit default swaps. Inthe framework of first passage time models, we...

This paper suggests spatial models as an alternative to the Armington approach to model bilateral trade. While the use of spatial models has been accepted for decades, they are rarely chosen for such analyses. However, problems inherent in the application of the Armington approach can be...

In der WTO-Agrarhandelsrunde von Doha geht es neben dem Abbau von Exportsubventionen und der Abschaffung von Marktzugangsbeschränkungen auch um die weitere Reduktion von internen Subventionen, die als produktions- und damit handelsverzerrend eingestuft sind. Eine Gruppe von Ländern, darunter...

We propose a simple and implementable model of credit contagion where we in-clude macro- and microstructural dependencies among the debtors within a creditportfolio. We show that, even for diversified portfolios, moderate microstructuraldependencies have already a significant impact on the tails...

We present a multi-period mean-variance optimization program which allows for a joint optimization of the balance and off-balance sheet. Our first finding is the proof of a conjecture of Li and Ng (cf. [LN00]), Leippold, Trojani and Vanini (cf. [LTV04], [LTV03]) about the equivalence of the...

In this paper operational risk are considered from a purely business or profitability point of view. We show for quantifiable operational risk that the three basic figures for profitability management - value, costs and risks - can be modelled such that an integrative point of view on...

Credit limit management is of paramount importance for successful short-term credit-risk management, even more so when the situation in credit and financial markets is tense. We consider a continuous-time model where the credit provider and the credit taker interact within a game-theoretic...
