In this paper we have studied the dependence between pollution and economic results, taking Romania as study case. Among the pollution level indicators we have chosen greenhouse gas emissions, and as economic results indicator we have chosen the GDP per capita. We started by explaining the...

This paper uses a neoclassical open economy general equilibrium model to determine the effects of the budget deficit and national debt on some key domestic variables while examining the interdependence and repercussion effects between the U.S. economy and the rest of the world. The empirical...

Linear regression model involves the identification of variables for defining specification for variable and model residuals; the context in which the regression model is used. Analysis of chronological (time) using a temporal function which, in essence, is also a regression, with a variable...

This article analyzes the evolution of the gross domestic product per inhabitant correlated with the variation of the employment rate by participation in economic activity in the eight development regions of Romania in 2000-2012 period. To achieve the correlation between the two indicators, the...

This paper estimates the welfare-optimal market share of wind and solar power; explicitly taking into account their output variability. We present a theoretical valuation framework that consistently accounts for output variability over time; forecast errors; and the location of generators in the...

На основании анализа действующей практики учета рассмотрены основные рекомендации по управленческому учету затрат в птицеводческих организациях. Предложены...

This article shows the evolution of the main macroeconomic indicators of results, Gross Domestic Product correlated with variation of final consumption in our country in the years 1990 to 2011. The values of the two macroeconomic indicators have been deflated using the consumer price index with...

Nowadays the Romanian society determines substantial changes in its structures working by the whole international integration mechanisms adopted by the European Union. The agricultural policy represents an appropriate expression of the integration principles as well as the efforts involved in...

OLS is considered to be, by far, the most popular and well-known method for estimating parameters of multiple regression. In this case, however, it is important to underline that there is no warranty as to the fact that OLS estimators will be, in one way or another, some “perfect” estimators.

Las realidades y las necesidades modernas demandan la urgencia de cambios en las prácticas educativas en la enseñanza de idiomas para alcanzar resultados superiores en poco tiempo y con costos accesibles. El impacto de las nuevas tecnologías educativas en la enseñanza posibilita el empleo de...

Marketing experiment is a set of operations, performed in a well defined and controlled environment, in which intentionally and repeatedly changes are caused among the factors of influence, identifying and then measuring the changes recorded by the effects.

In this paper, the authors present some considerations regarding the use of the multifactorial regression model in the statistical analysis of economical phenomenon. The paper comprises the steps necessary t determine the parameters of the model, the testing of model and the interpretation of...

This paper presents the results of the researches performed by the author regarding the evolution of Gross Domestic Product. One of the main aspects of GDP analysis is the correlation with the final consumption, an important macroeconomic indicator. The evolution of the Gross Domestic Product is...

This paper uses a unique data set on more than 600,000 mortgagecontracts to estimate a credit supply function which allows for risk-heterogeneity. Non-linearity is modeled using quantile regressions. Wepropose an instrumental variable approach in which changes in the taxtreatment of housing...

Logistic regression is a multivariate analysis method of marketing information becoming more and more used because the number of conditions that must be achieved are lower than, for example, in the case of discriminant analysis. The purpose of this paper is to obtain information using logistic...

In this paper we describe how you can implement a multi-agent computational model of trade using NetLogo. We did a number of 12 computer experiments. The first five experiments are dealing with the case when resources are renewable and trade is opened. The next five computer experiments are...

This paper ranks within the field of marketing research, being primarily aimed at identifying differences between the attitude of Romanian tourists as compared to that of foreign tourists with respect to hotel room arrangement - in which they were housed during their staying – respectively the...

Any activity or economic effort is based on a number of unknown and uncertain factors or opportunities simply because its subject is located in the future. All decisions or actions that will lead to a production process or act of foreign trade is inevitably initiated or taken in circumstances of...

In this paper we intend to present some theoretical approaches regarding measuring of the main determinants influence on inflation and based on these determinations to present the developments observed in the Romanian economy. Inflationary process is in the spotlight of all the world...

Many methods of multivariate analysis are based on metric variables. In the case of questionnaire-based surveys qualitative data usually prevail, measured nominally or ordinal. This paper contains the discriminant analysis from data recorded from a sample of 100 respondents, with regard to:...

In diesem Beitrag wird mit Galtungs Konzept der „Suche und Brechung von Invarianzen“ einin der betriebswirtschaftlichen Diskussion um die Kausalanalyse kaum beachtetes Konzeptzum Umgang mit festgestellten Wirkungszusammenhängen vorgestellt. Dabei wirdinsbesondere die Rolle der...

The object of research - absorption, variable, activity-based and backflush cost accounting systems.The aim of research – after the comparison of cost accounting systems will be performed, with reference to data received from questionnaires, to reveal the appliance of cost accounting systems...

The subject of the research is production costs classification used in the Lithuanian manufacture enterprises and farmers’ farms.The goal of the work is to reason the expedience of selection of the classification features in practice and to measure the adaptation opportunities of the selected...

In this paper we examine the concept of “vulnerability” within the context of incomemobility of the poor. We test for the dynamics of vulnerable households in the UKusing Waves 1 - 12 of the British Household Panel Study and find that, of threedifferent types of risks that we test for,...

I derive the exact small sample properties of the instrumental variables estimator using a trigonometric approach. The distribution for the estimation error is decomposed into a product of three components - each with an intuitive interpretation. This approach helps the discussion on what...

This paper illustrates the application of functional-equations results in population ethics.In an intertemporal framework, we provide characterizations of several classes of variablepopulationsocial orderings that may depend on individual lengths of life in addition tolifetime utilities...

Vorliegendes Arbeitspapier zeigt die experimentelle Untersuchung von drei ausgewählten Einflußfaktoren bei einer für das integrationsorientierte Reengineering typischen Aufgabenstellung.

Health diagnosis indicators used as explanatory variables in econometric models often suffer from substantial measurement error. This measurement error can lead to seriously biased inferences about the effects of health conditions on the outcome measure of interest, and the bias generally spills...

Convex output set is a common hypothesis in production theory and especially in empirical applications. This often seems to be taken for granted without any reference to returns to scale. However increasing returns to scale have implied a necessary and fundamental revision of general equilibrium...
