This research examines several modellers of immigration flows deployed within the European Union (EU), as well as their economic consequences upon the most targeted ten migrant receiving countries. The paper's aim is to identify specific ways in which migrants can contribute to host countries' sustainable development through positive spillover upon natives, labour market performance, and the overall economic activity. A set of methods and macro-econometric models, based on country fixed effects, spatial analysis, and structural equations modelling, was applied on a balanced panel formed by ten EU host economies. We analysed distinctly the labour and humanitarian (asylum seekers) migration flows, considered throughout two separate time periods, namely 2000-2015 and 2000-2019 (2019 being the deadline for Brexit negotiations). The results highlight that the immigration flows were mainly shaped by labour market outcomes, while the primary positive immigration impact was induced upon the gross domestic product (GDP) per capita and employment levels, both for natives and the foreign population.

Public food organizations have come in a relatively short period of time to operate in a highly complex business environment. As a result, quality and especially food safety became elements with new values, in a multidimensional approach of economy consumption. Simultaneously, the globalization of economic and social life has highlighted the need for a unitary approach on how to produce quality and safe products for the final consumer. For this reason, at the international level a series of standards have emerged that organizations have to follow to design, implement and certify food quality and safety management systems that benefit all parties involved. The present paper aims at carrying out a comparative study of certification schemes of food safety management systems in an attempt to give organizations the opportunity to understand what type of quality management system is appropriate to the organizational framework in which they are located, according with established objectives. The research is based on a comprehensive study of specific literature, articles and reference papers, the collection of data being carried out through comparative analysis of international standards, private certification schemes for food safety management products and systems, in the desire to clarify the different approaches but also the similarities and differences between them.

This paper aims at providing a different approach to international migration analysis, beyond classical models previously proposed by specialized literature. Chaos theory is getting more and more applied into macroeconomics once traditional linear models or even previous dynamic analysis become less suitable. Modern science sees chaos as unpredictable evolution, maybe even disorder. Still, chaos has got its own rules and can describe many dynamic phenomena within our world. Thus, we test whether international migration data falls under the rules of chaos and whether recent developments within the "European migration crisis" (the total daily migration inflows towards the coasts of Italy, by sea,

Based on the data series on environmental protection expenditure and the evolution of the GDP, this research examines the congruent influence of the environmental protection expenditure in Romania on the economic growth. The first section of the research includes the experimental part, with a brief presentation of the data used and the methodology. The following section presents the outcomes, the debate and the conclusions. The research provides evidence of the influence of environmental spending by different producer groups in order to explain some fluctuations in the GDP growth in Romania.

The academic literature analyzes the fiscality concern from all points of view, and the question which pressed upon the theoreticians and also the practitioners of the last decades remains: which is the adequate level of the fiscality? The difficulty in answering the question consists in opposite interests: on one hand, the government is willing to acquire the highest level due to the ascendant tendency of public expenses; on the other hand, the tax payers long for a much reduced level in order to dispose of more financial funds. Considering the theory of Arthur Laffer as well as the premise that the taxation structure (flat or progressive tax) is less important than the general level of taxation (tax burden), the purpose of this paper consists in the empirical analysis of the correlation between the tax pressure rate, GDP and the tax incomes flux within two States which adopt different tax systems: Romania and Turkey. For this purpose, we have described the methodology of creating the Laffer curve for Romania and Turkey and we have applied the methods concerning the analysis between the GDP and real tax systems, as well as those methods which estimate the empirical tendency of the fiscality rate within the two States, mentioned above, taking into account the parameters which determine it. The conclusion indicates the existence of a correlation between the real GDP and the real tax incomes, strongly
