In dieser Studie wird untersucht, inwieweit die Lebensbedingungen in der Kindheit und das Ausmaß sozialer Ungleichheit die individuelle Chance beeinflussen, erfolgreich, das heißt gesund und aktiv, zu altern. Europaweite Daten, die im Rahmen der SHARELängsschnittstudie erhoben wurden,...

Personen aus wohlhabenden Haushalten haben in Deutschland im Alter von 65 Jahren eine höhere Lebenserwartung als Personen mit niedrigen Einkommen. Bei Männern macht diese Differenz fünf Jahre, bei Frauen dreieinhalb Jahre aus. Die Analyse auf Basis des Sozio-oekonomischen Panels (SOEP) legt...

This paper examines the consequences of using self-reported measures of BMI when estimating the effect of BMI on income for women using both Irish and US data. We find that self-reported BMI is subject to substantial measurement error and that this error deviates from classical measurement...

We propose simple modifications for the Kakwani tax progressivity measure that make it suitable for evaluating access inequality for medical services. Our modification is to measure inequality using the ratio of the concentration index to the Gini coefficient instead of the difference between...

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...
