When there are many attributes, experiments with Conjoint Analysis include problems of information overload that affect the validity of such experiments. The impact of these problems can be avoided or reduced by using Hierarchical Information Integration (HII). The present work aims to...

Using the maximum likelihood method, in order to estimate Half-Normal stochastic frontier production models, entails several practical di±culties that, perhaps, have not been su±ciently emphasised. In employing FRONTIER software, we analyse the case in which the estimation obtained suggests...

The paper intends to measure the daily Value-at-Risk (VaR) for Rial-Euro exchange rate fluctuations risk. Since in this case we deal with a single risk factor, so we will not use the Monte Carlo simulation method to measure the VaR and we will only use the parametric and historical simulation...

Insurance companies have to estimate reserves and provisions to cover the payment of either unreported claims or unsettled claims. In this paper, we apply the Chain-Ladder method to obtain a point estimate of reserves, and then we use the bootstrap technique to estimate the margin of error and...

In some circumstances a decision maker, expert, in a group decision making problem cannot express his/her preferences with a unique linguistic fuzzy preference because he/she is dubious into some preferences. In this paper, we present a consensus model for group decision making problems with...

Contemporary research documents various psychological aspects of economic thought and decision-making. The main goal of our study is to analyze the role of the hindsight bias (Fischhoff [20]) and the anchoring bias (Tversky and Kahneman [53]) in perceiving economic and financial information,...

In October 2002, a substitution reform was introduced in the Swedish pharmaceuticals market. In this paper, the effects of increased price competition due to the reform on the entry of new pharmaceutical products were studied. The results show that the reform did affect the entry behavior of...

Das amerikanische Politmagazin Foreign Policy befragte zwischen August und September 2012 insgesamt 62 bekannte US-Ökonomen, worin sie die Hauptursache für die schleppende Erholung des Arbeitsmarkts sehen. Am häufigsten genannt wurde "Unsicherheit" (31 Prozent). Was ist mit diesem Begriff...

Disclosure of private medical information allows insurance companies to better predict medical expenditures. The premiums the companies charge the insured employees reflect these expenditures. This paper studies incentives of employees to disclose their medical information. I find that healthier...
