Aplicarea aparatului matematico-statistic în scopul estimării indicatorilor de creştere inovaţională
(IEFS, 2012) Susu-Turcan, Aurelia; Naval, Elvira
Existenţa unui sistem informaţional statistic coerent în domeniu inovării în Republica Moldova este o sarcină stringentă a societăţii, deoarece numai în acest caz este posibilă prognozarea calitativă a creşterii economice. În prezentul articol este prezentată o abordare în vederea evaluării statistice şi estimării indicatorilor inovaţionali. Oferta este modelată prin funcţia de producere tipul Cobb-Douglas. Productivitatea Totală a Factorilor nu depinde de factorii de producere, dar de alţi indicatori socio-economici.
Application of the econometric apparatus for estimating some parameters in the field of gender equality on the Moldovan labour market
(Performantica, 2019) Naval, Elvira; Colesnicova, Tatiana
The main goal of thisarticle is to evaluatethe perception ofgender inequality based on the selected data from the questionnaireon gender problems (latest results), elaborated by the team of the STCU project. From the twenty-eight indicators of this questionnaire there were selected five, namely: the perception of existence of inequality in the workplace, gender, age, the level of educationand the sector of economic activity. Using the obtained data, gender inequality in the workplace has been estimated in the paperwith the fourremaining indicators. As a result, a regression function was defined. The determined regression function was estimated and analyzed.

Dinamica răspândirii epidemiei virusului Omicron în Republica Moldova
(INCE, 2022) Naval, Elvira
New strain of the Coronavirus infection Omicron is more contagious than precedent one Delta. In the Republic of Moldova at this moment the number of infected achieves more than five thousand cases. Such situation affects health care system creating crises in hospitalisation. While the number of lethal cases are less than earlier, life of the human is threatened. To surpass such situation it is necessary to extend the number of disponible spaces to quarantine a portion of susceptible, exposed, and infected population, intending to reduce the spread of the coronavirus. The dynamic modelling of Omicron spread dynamic will be shown. The dynamic system of Omicron spread without optimal control will be formulated, aimed to minimize the number of infected population.
Evoluția virusului Omicron şi a virusului gripal în Moldova
(INCE, 2023) Naval, Elvira
New strain Omicron of the Coronavirus infection together with influenza virus is more contagious than only Omicron by itself. While numbers of lethal cases are less than earlier, life of the human is threatened, especially, in case of the children of an early age. Pontryagin Maximum Principle will be applied to the dynamic modeling of Omicron and Influenza virus in order to determine optimal solution aimed to minimize the number of infected population and control measures.
Impactul diminuării discriminării de gen asupra creşterii sustenabile în Republica Moldova
(INCE, 2018) Colesnicova, Tatiana; Naval, Elvira
The main goal of this article is referred to evaluating of a production function depending of two factors of production: capital and labor, labor being separated into man and woman involved in production processes. Optimization problem was formulated and solved. It is necessary to maximize Gross Domestic Product supposed to labor restriction.
Inovarea şi creşterea economică în Republica Moldova
(IEFS, 2011) Naval, Elvira; Timus, Angela
Modelul de creştere endogenă de tipul Paul Romer, ce permite comensurarea cunoştinţelor şi inovaţiilor a fost adaptat la condiţiile Republicii Moldova. În acest model sectorul Cercetare-dezvoltare este examinat în calitate de sector de producţie separat, care utilizează cunoştinţele ca factor de producere pentru sporirea productivităţii marginale. În acest model se arată că o creştere economică echilibrată este determinată de randamentul brevetului de invenţie şi rata de discont dar şi de parametri politicii statului în domeniul inovaţiilor.
Modelarea creşterii economice bazate pe cercetare-dezvoltare
(IEFS, 2011) Naval, Elvira
In this paper endogenous growth models bazed on the R&D are discassed. Starting with the argumentation that ideas or knowledge are one type of the public goods, which are non-reval and non-excludable, imperfect competition is necessary condition for technical progress appearence. The existence of monopoly rents incentivize private agents to do research, resulting in the creation of new products and production processes. Two types of the models are examined. The quality-ladder model of growth in which technological advancement is built on the process of creative destruction. And the model of variety expansion where increasing of inputs drives long-run growth. The problem of its models adaptation to the Moldavian economy are examined. Conclusions and proposals are given.

The multiple criteria optimization model for the Republic of Moldova
(Performantica, 2020) Naval, Elvira
The main goal of this article is to present optimization model for Moldova with multiple criteria, based on the input-output and computable general equilibrium approaches. Here demand and supply models are studied as integrated one composite input-output model. Such presentation carries on the fact that input-output models have dual presentation in demand and supply models. Based on this principle, computable general equilibrium model was examined. Simultaneously, balanced prices between demand and supply were determined. Multiple criteria non-linear programming is applied to balance between output and as well as the prices of demand and supply. Equilibrium is obtained as optimal solution among multiple criteria non-linear programming solutions.

Some approaches to gender problem examination in Republic of Moldova
(Artifex, 2020) Naval, Elvira; Colesnicova, Tatiana
In this article four approaches to gender problem examination in Republic of Moldova were proposed and discussed. First of them is referred to Gross Domestic Product maximization in respect with women and men labor force used. Second approach deals with Mincer`s “Human capital earnings function” approach to evaluation of the budget employees from one research institute. Stat data about wages payments for all categories of employees were used. Third approach represents an attempt to apply Markov chain for gender problem solving. Diagonal transition matrix was constructed. Problem of eigenvalues finding was solved and national economy stability problem was discussed. And the last approach considers gender inequality based on the selected data from the questionnaire on gender problems. Five indicators, namely: the perception of existence of inequality in the workplace, gender, age, the level of education and the sector of economic activity were selected. Regression function was defined, estimated and analysed.
Theoretical and methodological approaches on the evaluation of business incubatorst
(,,Victor Slăvescu” Centre For Financial And Monetary Research, 2014) Doga-Mirzac, Mariana; Naval, Elvira
The experience of developed countries on business incubators reveal that these establishments enable the entrepreneurs to focus on business development, job creation, and help foster interactions between entrepreneurs in a dynamic and innovative environment, which ultimately leads to the creation of small and medium sustainable entreprises. The incubator’s intensity and successful promotion of viable businesses depends on their level of development and quality. Therefore, for the evaluation of business incubators it is required to use certain indicators in order to detect factors that hinder their effectiveness. The success of a business incubator is its value to the economic environment and the ability to react quickly to changing external conditions.
