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...

The era of US state branching deregulation started in 1970 and ended up with the enactment of the Riegle Neal Act of 1994. One of the purposes of the branching restriction was to avoid bank concentration. The following paper addresses the influence of the state deregulation on commercial...

This paper analyzes entry deterrence strategies at sequential multi-unit Englishtype repeated auctions, motivated by entry deterrence observed at a series of yearly auctions of fishing rights occurring since the early 1990s in the Chilean Sea Bass industrial fishery. It analyzes parametric...

The recent crisis of 2008 has revealed several challenges for the economic science, sparking a considerable amount of debate regarding the profession of economists and the role of macroeconomics and monetary policies. The first question that arose was why there was a lack of anticipation of the...

In this paper we attempt to determine whether the Chinese foreign exchange reserves have been too large. We empirically analyzed the foreign exchange reserves first by using the rate analysis method and then using the cost-profit method. Using the rate analysis method we found that the Chinese...

In recent years the issue of the role of asset prices in monetary setting has become increasingly topical since booms and busts in asset market are associated with the fluctuations in overall economic activity through its impacts on aggregate spending. In this study, we use Smooth Transition...
