The basic idea when evaluating the companies on the basis of the cash-flows expected to e generated in the future consists of up-dating the available cash-flows at an appropriate rate of the expected yield. However, the matter gets complicated if considering the fact that we can utilize both the...

In this paper, we give the mathematical theory of the credibility model incorporating risk volumes. In the simple model of Section 1, we assumed that the risk volume was the same for all years. Often, in particular in reinsurance, one wants to allow for varying risk volumes, and for that purpose...

The analyzed models are grounded on macroeconomical variable, having the following common factors: inflation, interest rate, interest differences between risk bonds and interest without risc, interest differences between long tems bonds and short terms bond, the economical increase of the...

The idea of considering regression credibility models originated from Hachemeister. Just like in the case of classical credibility models, we will obtain a credibility solution in the form of a linear combination of the individual estimate (based on the data of a particular state) and the...

In many cases there is more than one risk factor dividing the portfolio in different subclasses or sectors. One could for instance consider a first subdivision in industrial fire insurance and fire insurance covering private households. Other risk factors may be used to further classify the...

Intangible assets are the most important sources of competitive advantage. According to the new perspective supported by endogenous growth theory, the traditional factors of production have diminished the importance. Simultaneously, increased the importance of intangible assets, which is an...

The evolution of Accounting during the transition to a market economy has demonstrated the existence of a special methodology of gathering, processing and providing information related to modern Accounting, based on specific informational system. Accounting may offer a model, as a means of...

This is an original paper, which analyses some practical insurance problems of non-life insurance, with applications in the actuarial calculations that can be solved by means of credibility theory. Examples of the credibility results for the linearized premiums, as other applications for the...

In this paper, we give the mathematical theory of the hierarchical credibility model, which consists of a portfolio of contracts, for homogeneous linear credibility estimators. The theorem obtained (see section 1) shows that this happens to give the optimal unbiased homogeneous liniarized...

In this paper, the authors measure, with the help of a multiple regression model, the links between the value of average social insurance pension, as resultant variable, and as factorial variables, gross average salary, annual inflation ratio and the annual evolution of GDP. The model is applied...
