The following research is guided by the hypothesis, that products chosen on a shopping trip in a supermarket are an indicator of the preference interdependencies between different products or brands. The bundle chosen on the trip can be regarded as an indicator of a global utility function. More...

The paper describes our experience with the production of electronic textbooks. Electronic books are defined as supplements to usual printed textbooks. The first part of the paper describes the technical background of our electronic book system. In the second part we describe how this system can...

Many mathematical and statistical questions require the use of computational assistance. The proposed XploRe Quantlet Client (XQC) with it's combined CUI and GUI interface gives access to the XploRe software environment (XploRe Quantlet Server - XQS) with it's large number of available...

Because of its relation to economic growth, there is a policy interest in mea- suring social capital and average trust as its currently most important proxy. Thereby a main focus is determining its variation across groups with different individual characteristics. In this paper we combine the...

Nonparametric methods for estimating the implied volatility surface or the implied volatility smile are very popular, since they do not impose a specific functional form on the estimate. Traditionally, these methods are two-step estimators. The first step requires to extract implied volatility...

The use of electronic spreadsheets as the primary software tool for teaching management science modeling techniques and quantitative methods in economics and finance undoubtedly played a key role in the increasing impact of quantitative lectures given in graduate programs. Researchers suggest...

This paper combines an economic experiment with survey data to investigate determinants of trust and trustworthiness in the Dutch society. We contrast the inferences which can be made on the trust propensity using stated and revealed measures and we test for participation bias in our experiment....

In regression analysis there is typically a large collection of competing models available from which we want to select an appropriate one. This paper is concerned with asymptotic properties of procedures for selecting linear models, which are based on certain data-dependent criteria such as...

In this study we illustrate a Maximum Entropy (ME) methodology for modeling incomplete information and learning from repeated samples. The basis for this method has its roots in information theory and builds on the classical maximum entropy work of Janes (1957). We illustrate the use of this...

In some applications, the population characteristics of main interest can be found in the tails of the distribution function. The study of risk of extreme events will lead to the use of probability distributions and the scenarios that correspond to the tail of these distributions. Considering...
