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...

Analysis (DEA) have become very popular in the analysis of productive efficiency. This paper undertakes a comparison of the SFA and the constant returns to scale (CRS) and variable returns to scale (VRS) output-oriented DEA models, based on a sample of 165 dairy farms in Greece. However, the aim...

This study compares activity-based costing (ABC) model and traditional costing method in Malaysia. Activity based costing (ABC) which was developed into the manufacturing/service sectors in Malaysia. It calculates the cost and performance of activities, resources and cost objects. It can be...

Die Befristung von Arbeitsverträgen hat in den letzten Jahren zunehmend an Bedeutung gewonnen. In der Folge wird auch intensiv über die positiven wie negativen Effekte dieser Beschäftigungsform diskutiert. Die Debatte beschränkt sich jedoch im Wesentlichen auf Arbeitsmarktaspekte und die...

Die industrielle Forschung hat in den vergangenen zehn Jahren expandiert. Sowohl die Zahl der forschenden Unternehmen als auch die Beschäftigung in Forschung und Entwicklung und die finanziellen Aufwendungen in diesem Bereich haben deutlich zugenommen. Zuwächse gab es vor allem bei Unternehmen...

The purpose of this study is to develop a methodology in measuring productivity growth by decomposing it into technical change and technical efficiency change in India's paper industry. The prime objective of this article is to assess the impact of liberalization on productivity growth of...
