Over the last decades, significant improvements in life expectancy have been observed in most Western countries. More importantly, there is considerable uncertainty regarding the future development of life expectancy. This uncertainty imposes significant risk on pension providers and life...

We characterize the effects of different methods of taxing multinational income on productive efficiency in a competitive equilibrium. The efficient outcome is achieved when every firm that produces and sells domestically faces the same tax rate as a multinational firm selling into the same...

This paper develops a model of a firm's foreign investment decisions and characterizes its optimal investment and repatriation strategies. It then derives the theoretical relation between firm value and the book value of the deferred tax liability associated with such investments or, if no...

In this paper we consider an insurer who has incomplete information about the claim frequency of the risk process. He therefore calculates the premium on the basis of a prior distribution for the claim frequency. Future information might then reveal that it is no longer optimal for the insurer...

The rate of return earned on a deposit can depend on its term, the amount of money invested in it, or both. Most banks, for example, offer a higher interest rate for longer term deposits. This implies that if one individual has capital available for investment now, but needs it in the next...

This paper introduces the family of Weighted Aumann-Shapley values for piecewise linear fuzzy games. The regular Aumann-Shapley value is not well-defined in case some differentiability condition is not satisfied. As an alternative, we introduce a family of allocation rules inspired by the...

Existing literature regarding the natural hedge potential that arises from combining liabilities with different sensitivities focuses on the optimal liability mix, but does not address the question whether and how changes in the liability mix can be obtained. In the absence of a well-functioning...

We consider longevity risk hedging problems, where survivor swaps are available as hedging instruments. As objective functions we consider the mean-variance and the mean-conditional-value-at-risk of the hedged liabilities, evaluated using an estimated probability law governing the mortality...

Forecasted mortality rates using mortality models proposed in the recent literature are sensitive to the sample size. In this paper we propose a method based on Bayesian learning to determine model-specific posterior distributions of the sample sizes. In particular, the sample size is included...

Changing management accounting systems requires more than appropriate implementation. It is argued that structural characteristics of an organization, centralization in particular, should also be taken into account when deciding on a change. Centralization implies higher costs of communication...
