The objective of the analysis is to study the relationships between GDP, energy consumption, renewable energy production, and CO 2 emissions in some European transition economies in the period 1990-2018. We use the growth rates of per capita values, in a panel VAR approach where all variables are typically treated as endogenous, allowing some inference on the causality of the relationships. The decision to focus on European transition countries is motivated by the fact that a significant part of the future of the green economy in Europe depends on the environmental and energy policies that will be implemented by these countries. In the transition economies (and years) included in the analysis, our findings suggest that investing in energy efficiency is good for the competitiveness of economies (in terms of effects on GDP growth) and is good for the environment (in terms of diminishing CO 2 emissions). Finally, an increasing production of renewable energies reduces CO 2 emissions.

Continuously, the relation between education and economic development has been the focus of development researchers' studies that study long-term growth. While theoretical models recognize education as the key to a country's economic growth (Bassanini and Scarpetta, 2001;Fuente and Ciccone, 2003; Jones, 2005 Bassanini, 2007, the importance of education is very low in empirical models.The reason for this discrepancy is that for a long time education is measured by the years attended in school and not by the knowledge and skills gained, which according to an OSCE study, a student competences growth of 100 points (measuring unit) produces an increase of 2% of GDP per capita. Thanks to this identification, education is recognized as one of the main keys to development.Various empirical studies show that productivity can be increased through training (Barrett and O'Connell, 2001; Scrutinio et al., 2006). In sum, these studies show that pre university, university education and training courses positively affect the increase of production, which

Over the past decade, the air transport system has undergone profound changes, mainly driven by the evolution of reference legislation and markets globalization process. The primary cause also goes by the name of "deregulation", which has profoundly revolutionized the tariff methodology and air transport management.With deregulation, airlines have seen disappear of barriers and constraints that incentivized growth and development for many years (Arrigo, Giuricin, 2006; Postorino, 2009).The globalization of markets has also proved decisive in the growth of demand for air transport, which has become an irreplaceable means of transfer that allows the connection from one part of the terrestrial globe to another in a few hours. Impressive growth in air traffic and deregulation has at the same time led to millions of frequent passengers and unpleasant complications, such as delays. In the absence of a specific discipline in this area and with the desire to give balance to a situation partially unbalanced to the detriment of consumers/travelers, the European Union decided to take action to remedy it, equipping passengers with effective protection tools against these afore mentioned situations.The European Union has made the rules issued in 1991 on compensation and assistance to air passengers more rigid and afflictive for airlines by providing, at the same time, new provisions aimed at mitigating the inconvenience of passengers abandoned at airports due to canceled flights or of prolonged delays. The EU legislation covering these changes, which was preceded by the Passenger Rights White Paper, is contained in EU Regulation 261/1994, which came into force in February 2005, which sets out how and operational rules on assistance and reimbursement to air traffic users (Fraschina, 2009).The three different hypotheses of "denied boarding", cancelled flights and prolonged delays are the subject of regulation.In this study, however, we will mainly address the rights and reimbursement of passengers in the event of delays of air flights, in fact according to the new legislation, more protection will be provided to passengers who will face the painful and common circumstances of the delays. Community bodies believed that adequate assistance and reimbursement should be provided to passengers who were forced to long waits at airports due to a flight delay.

Attracting FDI is top priority to Albania not only to finance its budgets, but moreover to improve the economic development and standard of living. High inflow of FDI can increase efficiency of the production and introduce new products on the markets. Experience has shown that foreign direct investment has had a major impact on the economic growth of a country. Some of these benefits are: a) increase in competitive potential between domestic production enterprises. b) the entrance of advanced technology c) progress in knowledge of various fields of production resulting from contacts with foreign customers d) possibilities for the optimal utilization of human resources and help to increase their professional skills etc. In this paper we will analyze FDI on a national introducing three models: the first model is going to analyse the monetary policies, then fiscal policies and in the end
