We analyze the determinants of interest rate spreads of different loan categories in the Czech Republic during 2004–2011. We employ a detailed bank supervisory dataset that allows us to construct the actual spreads for four loan categories, namely small and large corporate loans, consumer...

This paper analyses problems within the asymmetric information models (principal agent models) where we replace standard assumption of maximisation of expected income by maximisation of probability of economic survival. This paper concentrates on two basic models - adverse selection model and...

This article shows that the altruism of the donator could have different forms. The specific form of his optimisation criterion significantly influences his decision making concerning the allocation of his resources among recipients. Moreover, even within one chosen criterion we could report...

The St Petersburg paradox could be used as an extreme demonstration of the utility function cardinalisation in case of stochastic utility. In this article we reassume the von Neumann and Mongernstern explanation to this paradox based on the risk aversion expressed by the strict concavity of the...

This paper is an attempt to grasp and model the problem of optimal strategy of a firm under conditions of unremitting increase of returns to scale and multiple threats of firm's downfall. The firm in our model has to pay high fixed costs to enter the market and its marginal costs are...

According to the effective market theory, the stock prize on an effective market is the best estimate of the stock's current value. This is the basic assumption for predictions using experimental markets. This article describes the first experimental market organised in the Czech Republic, the...

This article, based on an empirical analysis, discusses factors affecting property prices and tries to identify periods of property price overvaluation in the Czech Republic. To achieve this, the article uses both relatively simple approach using ratios related to the house prices (e.g....

This paper presents the results of a comparison of an original theoretical concept of modeling human decisions under risk with two well-known models. In the paper the demand function for insurance is constructed for the model of maximization of the probability of agent’s (economical) survival....

This paper analyses problems within the asymmetric information models (principal agent models) where we replace standard assumption of maximisation of expected income by maximisation of probability of economic survival. This paper concentrates on two basic models- adverse selection model and...

According to efficient markets theory, the stock price on a competitive market is the best estimate of the stock’s present value. This is the basic assumption for predictions using experimental markets. The first part of the paper describes the features of such an experimental market,...
