    Legătura dintre populație și dezvoltarea durabilă la nivelul economiei românești
    (INCE, 2022) Savu, Mihaela; Delia, Teselios
    The paper aims to present the link between population and sustainable development, through specific indicators: the number of the population and the human development index. In the last 20 years, at the level of Romania, a continuous reduction in the number of the population can be observed, which leads to the aging of the population, with a strong impact on the economy. Using correlation and regression, two statistical methods for highlighting the link between variables, we analyze the existing relationship between the number of the population and the human development index at the level of the Romanian economy, over a period of 10 years. The analysis of the two indicators is carried out with the help of the Excel spreadsheet program, Data Analysis. The results provided by Excel after entering the values recorded by the number of the population and the human development index demonstrate that there is a strong relationship between these indicators. The value of the human development index provided by the official data is recorded for 2 or 3 years ago, so we can compensate for this shortcoming through the regression function. The obtained results allow us to present the existing regression function between the indicators and to be able to determine the value of the human development index knowing the number of the population, because this information is provided at the beginning and in the middle of each year.

    The relationship between the average monthly net wage and permanent emigrants in Romania.
    (2023) Savu, Mihaela; Teselios, Delia
    The paper aims to present the relationship between the average monthly net wage and permanent emigrants at the level of our country for a period of 12 years. At the level of Romania, in the last 30 years, the trend of emigration has been observed, especially for obtaining higher incomes than those that could be earned in the country. In (the year) 2021, the top three countries chosen by permanent emigrants were Spain, Germany and Italy. They keep their place in the top three countries chosen for emigration in the last five years of the analyzed period. We consider that the presentation of the two indicators will allow us to observe the relationship between them, using one of the non-parametric methods for establishing the link between statistical variables, namely the Kendall coefficient. The analysis of the two indicators is carried out with the help of the rank method, a statistical method, which involves establishing the ranks (position) for the values of the two indicators for the entire analyzed period. The values recorded by the average monthly net salary and permanent emigrants are official data, provided by the National Institute of Statistics. The result obtained after calculating the Kendall coefficient demonstrates that there is a link between these indicators, it is direct and of medium intensity. These information allows us to conclude that the level of salary earnings in Romania is one of the decisive factors in making the decision to emigrate.
