In this paper, I examine an inter-temporal exchange economy with a complete financial market. The economy is populated by two heterogeneous investors who differ from each other in their attitudes towards risk. In such a model, a single representative agent can be created who generates the same...

Banking reform has proved to be one of the most problematic elements of economic transition in central and Eastern Europe. Therefore the paper considers the development of the Estonian banking sector and derives individual banks´ fragility scores during transition. To this end we use...

We consider optimal stopping problems for ambiguity averse decision makers with multiple priors. In general, backward induction fails. If, however, the class of priors is time-consistent, we establish a generalization of the classical theory of optimal stopping. To this end, we develop first...

The paper derives a valuation formula for the real option of a firm to undertake an irreversible investment in a foreign economy based on the endogenous dynamics of a stochastic macroeconomic framework with sluggish price adjustment. The option valuation formula is implemented to analyze the...

Capital flight has characterized the transformation process in Russia. Inflows of foreign direct investment have been minor and have been preceeded by inflows of portfolio capital. The paper shows that uncertainty about macroeconomic stabilization exhibits a strong negative effect on the volume...

In this article we use contingent-claim analysis to calculate the effective tax rate (ETR) under corporate debt finance. In particular, we deal with both pure debt and two of the most well-known hybrid securities, i.e., convertible, and reverse convertible bonds. We show that: 1) effective...

This paper considers the problem of model uncertainty in the case of multi-asset volatility models and discusses the use of model averaging techniques as a way of dealing with the risk of inadvertently using false models in portfolio management. In particular, it is shown that under certain...

Das Arbeitspapier behandelt die verschiedenen Möglichkeiten zur Optionspreisbestimmung. Es beginnt mit einer Abhandlung der theoretischen Grundlagen und stellt danach unterschiedliche Modelle dar, bspw. Black-Scholes-Modell; Cox-Ross-Rubinstein-Modell usw.

One of the central goals in finance is to find better models for pricing and hedging financial derivatives such as call and put options. We present a semi-nonparametric approach to risk-neutral density extraction from option prices which is based on an extension of the concept of mixture density...

Motivated by previous findings that discretization of financial time series can effectively filter the data and reduce the noise, this experimental study compares the trading performance of predictive models based on different modelling paradigms in a realistic setting. Different methods ranging...
