Geometric Asian option pricing in general affine stochastic volatility models with jumps

In this paper, we present some results on Geometric Asian option valuation for affine stochastic volatility models with jumps. We shall provide a general framework into which several different valuation problems based on some average process can be cast, and we shall obtain closed form solutions for some relevant affine model classes.     

Missing the Popular Vote: Pitfalls in US Democracy and Reform Proposals

Intereconomics - Only a few years ago, it was a widespread belief that globalisation would trigger processes of democratisation worldwide. However, even old and established democracies such as the...     

Can Singapore maintain its competitive edge in manufacturing productivity vis-à-vis China and Malaysia?

This article investigates whether Singapore can maintain its competitive advantage in manufacturing from a labour productivity perspective vis-avis China and Malaysia, which are generally viewed as Singapore's competitors in manufacturing. We also investigate the extent to which China is closing the labour productivity gap with Singapore and Malaysia in technology-intensive segments of manufacturing. Our analysis reveals that China has the potential to develop a high labour-productivity and low-wage manufacturing sector. In terms of manufacturing labour productivity, China is moving towards convergence with Malaysia. Compared with Singapore, China's manufacturing labour productivity is still far behind, especially in key technology-intensive industries like electronics and chemicals, such that it is unlikely for China to catch up with Singapore within a decade.     

Rentenreform — mit welchem Fokus?

The demographic imbalance is aggravating, and by 2060 the old-age dependency ratio will double to approximately 70%. This development has consequences for the state pension system: growing contribution rates to social security coupled with lower pension levels, but at the same time a higher retirement age. The German pension scheme is mandatory for all wage and salary earners, but since 2001, no reasonable indicator for measuring the pension level exists any more. As a consequence of this, old-age pension has lost its traditional function as a replacement for earnings. The recent pension reforms have dropped the pension level sharply. Further reductions have been announced with the consequence of increasing old age poverty. Against this background it is proposed to raise the pension level so that the pensioners can maintain their standard of living. But any pension reform involves issues of distribution between and often also within generations, which cannot be addressed without explicit equity criteria. Some authors consider the past reforms as a mistake, others suggest adjustments.     

Der US-Dollar als Leitwährung – alternativlos?

The importance of the industrialized countries – including the USA – for world production has been declining for a long time. By contrast, China’s share in particular has increased significantly. Nevertheless, the US dollar has largely fulfilled the criteria for a leading currency function so far, even if this is increasingly criticised due to the protectionist rhetoric of the US. Accordingly, central banks worldwide hold their reserves primarily in US dollars and transactions are largely conducted in US currency. This position brings great advantages–such as making it easier for the US to monitor and enforce sanctions, among other things–and therefore great incentives for the US to maintain its position as the leading currency. Whether other currencies, especially the renminbi, will be able to fulfil the lead currency function is questionable. Similarly, it does not seem realistic that market participants will be able to engage in a global currency.     

Model-independent bounds for option prices—a mass transport approach

In this paper we investigate model-independent bounds for exotic options written on a risky asset using infinite-dimensional linear programming methods. Based on arguments from the theory of Monge–Kantorovich mass transport, we establish a dual version of the problem that has a natural financial interpretation in terms of semi-static hedging. In particular we prove that there is no duality gap.     

The advantages of a small European Monetary Union

The question whether European Monetary Union should include all the EC countries from the start or should initially be limited to a few core countries is again being discussed more intensely. What advantages would a small EMU have from an economic point of view? Which countries should be its founder members?
