Insuring against the shortfall risk associated with real options

We would like to insure against the risk that a geometric Brownian motion, correlated with the price process of a certain traded asset, is in a set E at time T. In this paper it is shown that the best action one can take to insure against this risk is to buy a binary option on the traded asset. We give explicit formulas in the case that E is an infinite interval. The setting of all our investigations is the Black-Scholes model.

Analyzing a panel of seasonal time series: Does seasonality in industrial production converge across Europe?

In this paper we consider deterministic seasonal variation in quarterly industrial production for several European countries, and we address the question whether this variation has become more similar across countries over time. Due to economic and institutional factors, one may expect convergence across business cycles. When these have similar characteristics as seasonal cycles, one may perhaps also find convergence in seasonality. To this aim, we propose a method that is based on treating the set of production series as a panel. By testing for the relevant parameter restrictions for moving window samples, we examine the hypothesis of convergence in deterministic seasonality while allowing for seasonal unit roots. Our main empirical finding is that there is no evidence for convergence in seasonality.     

External wealth, the trade balance, and the real exchange rate

We examine the link between the net foreign asset position, the trade balance and the real exchange rate. In particular, we decompose the impact of a country's net foreign asset position (‘external wealth’) on its long-run real exchange rate into two mechanisms: the relation between external wealth and the trade balance; and, holding fixed other determinants, a negative relation between the trade balance and the real exchange rate. We also provide additional evidence that the relative price of nontradables is an important channel linking the trade balance and the real exchange rate.     

Financial crisis in Southeast Asia: dispelling illusion the Minskyan way

This paper extends Minsky's financial instability hypothesisto the case of the open, ‘liberalised’, economy,making it possible to put forward a specifically Minskyan accountof the road to the financial crisis in Southeast Asia (1997/1998).The analysis suggests that the threats to growth and employmentemanating from the financial sector which Minsky identifiedin the closed economy setting are much intensified in open,liberalised, developing economies. Financial liberalisationis an important key factor in this process. Rival explanationsof the crisis are examined and rejected in favour of the extendedMinskyan explanation. The policy implications are derived anddiscussed.     

Ombudsman schemes in the United Kingdom's financial sector: The insurance ombudsman,the banking ombudsman,and the building societies ombudsman

The problems facing consumers in pursuing complaints against suppliers through the courts are well known and have given rise to the development of alternative strategies. This paper considers the development and use of one such strategy — the ombudsman — in dealing with the complaints of consumers against insurers, banks and building societies. The decisions to create these schemes can be seen against a background of the radical changes in the financial markets during the 1980s. However, the practice of the different ombudsmen is also influenced by the history, rules, practices and commercial contexts of their respective industries. It is argued, for instance, that the ombudsmen have developed standards of fairness which enable them to step outside established law and practice. However, the extent to which each is willing to do this may depend on the history and legal context of the relationships which a particular sector has had with its customers.

Ombudsmann-Regelungen im Finanzsektor Grobritanniens: Die Ombudspersonen für Versicherungen, für Banken und für Wohnbaugenossenschaften

Zusammenfassung Die Schwierigkeiten, die Konsumenten haben, wenn sie Beschwerden gegen Anbieter auf gerichtlichem Wege klären lassen wollen, sind gut bekannt und waren Anla\ für die Entwicklung alternativer Strategien. Der Beitrag behandelt eine dieser Alternativen — den Ombudsmann — bei der Behandlung von Verbraucherbeschwerden gegenüber Versicherern, Banken und Wohnbaugenossen-schaften. Die Entscheidungen, die zur Schaffung dieser Regelung geführt haben, sind vor allem vor dem Hintergrund der starken Veränderungen auf den Finanzmärkten in den 80er Jahren zu sehen. Dabei wird das praktische Vorgehen der Ombudspersonen von der Entstehungsgeschichte, von Gewohnheiten und Praktiken und vom wirtschaftlichen Zusammenhang ihrer jeweiligen Branche beeinflu\t. So haben die Ombudspersonen zum Beispiel Richtlinien für Fairne\ entwickelt, die ihnen auch Möglichkeiten au\erhalb der etablierten Bereiche des Rechts und der Praxis eröffnen. Allerdings hängt die Bereitschaft des einzelnen Ombudsmannes, solche Möglichkeiten zu ergreifen, von der Geschichte und dem rechtlichen Kontext der Beziehungen ab, die seine Branche mit ihren Kunden gehabt hat.
