The study presents alternative measures for measuring the welfare of a country in the context of identifying relationships generated by the impact of changes in the income level, measured by gross domestic product (GDP), related to other welfare, measured by the Happy Planet Index (HPI). The analysis was conducted in Romania, during the period from 2012 to 2016. The research methodology involves simple linear regression and welfare descriptive variables such as GDP, GDP/capita, HPI and its subcomponents’ indicators, namely life satisfaction, life expectancy and ecological footprint. Identification of aspects that have an impact on the welfare of citizens allows to compare levels of wellbeing experienced worldwide and to identify the main areas at the national level on which improvements can be made. The results indicate that, although there is no correlation between GDP and HPI, GDP/capita has great influence on both life satisfaction and life expectancy. Also, GDP has influence on the ecological footprint. Given these considerations, the main conclusion of the research is that, although the level of welfare, quantified using GDP, changes positively, this change is due to the increased life expectancy, life satisfaction, reduced ecological footprint rather than to changes in income levels.
The effective attraction of investments to the national economy is a key factor, which provides favourable conditions to perform structural changes in the national economy, regional development as well as promotes technical progress. Therefore, investments in the public and the private sectors conduce development of the national economy and provide conditions to increase the overall competitiveness of a country. The purpose of research is to evaluate investment processes in Latvia before and after the global financial crisis, revealing investment-related problems. Also, to calculate the level of the desired investment, which would ensure the Latvia’s average GDP growth of 5% per year, according to the target set by the NDP. The analysis employs different qualitative and quantitative analysis methods, such as: scientific literature and empirical research analysis, modelling tables, charts and schemes, calculations of average and relative values, grouping, comparison and other. Publications on investment and research by Latvian and international scholars are analysed seeking to define the investment role on the economic growth process. The authors use the data available in the Central Statistical Bureau of the Republic of Latvia and Eurostat data bases, reports by the Ministry of Economics of the Republic of Latvia, the World Bank, the OECD and other studies of international organizations, as well as information provided in the Internet. As a result of research there have been defined the investment policy directions and essential obstacles that delay investment attraction in Latvia.
