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...

Grey system theory can powerfully deal with incomplete and uncertain information. In this paper, we introduced an improved grey GM(1,1) model that integrates residual modification with Markov chain model. By this model, we improved the forecast accuracy of original grey forecast model and...

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...

In this paper I examine a taxpayer utility function determined by the extended set of variables - i.e. consumption, labor and tax-evasion propensity. This constitutes the main framework for the analysis of taxpayer's decision making process under assumption that in the economy there exist two...

Die hohe Mobilität der Bevölkerung trägt zur Teilhabe am Arbeitsmarkt und am gesellschaftlichen Leben bei. Dabei ist der Mobilitätsbedarf stark von der Lebenssituation abhängig; so haben Studenten und Erwerbstätige die höchste Verkehrsnachfrage. Anders als in früheren Jahrzehnten wächst...

Our paper assesses the accuracy of individuals ́tax perceptions. Based on personal interviews, we aim to find out how tax complexity affects the capability of respondents to calculate income tax liability. Tax complexity is measured by interacting multiple tax rates, applied to one or more tax...

Creation of optimal tax and budget systems is one of the Difficult problems of economic science. One of the most important areas of tax reform is to develop a tax code in the aspect of optimal tax gravity. The new tax code - a step to improvement, since a number of reduced taxes and simplified...

Tax burden is one of the important determinants in attracting foreign direct investment (FDI). In the case of Vietnam, the tax burden is considered a powerful tool that Vietnam has used to create a competitive advantage compared to other countries in the area to attract FDI flows. In addition to...
