External borrowing,capital formation and growth in developing countries

Since the summer of 1982 the banking community has been faced with an international debt crisis of unprecedented dimensions. The debt rescheduling agreements that have been negotiated since then involve sums totalling no less than $ 100 billion. However, they give the international financial system no more than a breathing-space. The following two articles deal with different aspects of this crisis. Rainer Erbe examines the question as to what growth effects were associated with external borrowing. Can a lack of growth effects be made responsible for the crisis or were other factors more important? This is followed by an article by Anton Konrad who discusses the proposals which have been made for long-term crisis management. What are their chances of success?     

Markov chain Monte Carlo analysis of underreported count data with an application to worker absenteeism

A new approach for modeling under-reported Poisson counts is developed. The parameters of the model are estimated by Markov Chain Monte Carlo simulation. An application to workers absenteeism data from the German Socio-Economic Panel illustrates the fruitfulness of the approach. Worker absenteeism and the level of pay are unrelated, but absence rates increase with firm size.     

Incentives of Stock Option Based Compensation

We introduce explicitly the effort as a choice variable in a continuous time utility maximisation framework of an executive who is partly compensated with stock options. We solve the model in the case where the executive is not allowed to trade in the company’s stock but is able to achieve a partial insurance through trading in a correlated market portfolio. We define the executive’s value of the options through a certainty equivalence approach both in the case of European call options and non-standard capped stock options and study the behaviour of the reservation price as relevant parameters change.JEL Classification: G13, G30, G32, J33, M12     

Income thresholds of dissaving in Germany: empirical evidence from the recent sample survey of income and expenditure (EVS 2008)

Saving of private households monotonically increases with income. If the regression lines, which represent the ‘demand for saving’, assume negative values, saving turns into dissaving, i.e. dissolving assets or going into debt. The zeros of the demand functions for saving are called ‘dissaving thresholds’. Dissaving thresholds for Germany are determined econometrically using the Sample Survey of Income and Expenditure. Dissaving thresholds turn out to be far higher than social assistance amounts. Implications for economic, social and consumer policy in Germany are discussed.     

Antecedents and consequences of effectuation and causation in the international new venture creation process

The selection of the entry mode in an international market is of key importance for the venture. A process-based perspective on entry mode selection can add to the International Business and International Entrepreneurship literature. Framing the international market entry as an entrepreneurial process, this paper analyzes the antecedents and consequences of causation and effectuation in the entry mode selection. For the analysis, regression-based techniques were used on a sample of 65 gazelles. The results indicate that experienced entrepreneurs tend to apply effectuation rather than causation, while uncertainty does not have a systematic influence. Entrepreneurs using causation-based international new venture creation processes tend to engage in export-type entry modes, while effectuation-based international new venture creation processes do not predetermine the entry mode.     

Konjunktur- und Strukturkomponenten der Länderhaushalte

Deutschland hat im August 2009 eine Schuldenregel im Grundgesetz verankert. Die Bundesl?nder müssen bis 2020 ihre Ausgaben grunds?tzlich ohne Kredite fi nanzieren. Konjunkturbedingte Defi zite sind weiterhin m?glich, die in konjunkturell guten Zeiten ausgeglichen werden müssen. Das RWI hat ein Verfahren entwickelt, wie die Konjunktur- und Strukturkomponenten der Landeshaushalte berechnet werden sollten.

Ein versicherungsmathematischer Ansatz zur Berechnung von Marktwerten der Deckungsrückstellung in der Lebensversicherung

Based on well-known actuarial calculation principles for the determination of the liabilities for life insurance contracts, we present a method for the calculation of fair values of liabilities. This method is consistent with the Solvency II requirements. The main principle is the discounting of probability weighted future cash flows, including assumptions on interest rates, costs and lapse for the calculation of actuarial present values. In addition to the mathematical framework, we discuss some numerical results that compare the traditional liabilities with the fair value approach. The presented principles are also relevant for the IFRS directives, which are at the moment available as exposure draft.
