Abstract The purpose of the thesis has been to investigate the relation between human capital and economic growth in developing countries around the world. The main research question is how the human capital impact on the economic growth in developing countries during the period of 2010 -2015.The world is mainly divided into two major groups, which are Developed & Developing countries, as well as poor & rich countries. In this thesis mainly concern only developing and poor countries and their role of the economic growth. The key factors of economic growth are GDP/capita, per capita income, birth rate, death rate, population growth rate, life expectancy at birth, working age population, education, literacy rate and investment in technology. The world is populated day by day such has never been before. In the past history it look back to 123 years to increased from one billion to two billion from 1804 to 1927.Then, next billion took 33 years. The following two billions took 14 years and 13 years, respectively (Ray, Development Economics).             The data has been taken from the Developing countries around the world which is taken a cross sectional data set and data has been analysed with multiple liner regressions model with ordinary least squares (OLS). For this purpose which applied the difference tools & theory which are human capital and technology development, economic growth, norms, externalities and human social capital.   The previous studies is examined the most important factors of economic development that is economic growth and human capital investment. Similarly, the theoretical discussion is described the Solow model, human capital theory, technological progress, demographic transition and social capital. For examine the data is divided into two groups which are dependent and independent variables. Economic growth GDP/capita, GDP/capita growth rate are dependent variable and Ln. GDP initial, life expectancy at birth, population growth rate, education, working age population and investment in technology are independent variables.   This analysis shows the majority of the variables in the study have positive significant relation to the GDP/capita growth. This result furthermore support the developing countries provides insight on the world economic development status towards the independents variables.

In this thesis we aim to examine the economic impact of peacekeeping provided by the United Nations (UN) in conflict-affected countries around the globe. The main interest of this thesis is to estimate the possible economic impact that UN peacekeeping operations may have had on conflict-affected countries’ economies between 1989-2019. We aim to do this by investigating if there is a positive causal relationship between UN peacekeeping operation (PKO) and GDP/capita. This is done by examining previous research and conducting an empirical analysis using a difference-in-differences method. Our model examines the change in GDP/capita levels for both a treatment and non-treatment group, defining PKO as treatment. Data on the conflicts, UN peacekeeping operations and other relevant variables was collected from well-established open sources. The results imply that PKO has a positive impact on GDP/capita development, but that the effect most likely goes through the effect that PKO has on our mediator variables, that in turn positively affect GDP levels. Furthermore, our results indicate that the size of the mission, in terms of military strength, does seem to increase the economic effect.

The purpose of the thesis has been to investigate whether there is a link between trade liberalism and economic growth in the Asian countries. Previous research has pointed out that correlation exists between these variables, but there have also been other researchers who criticized such a relationship. We discovered that economic growth studies had previously been conducted where countries in Asia were included. This motivated us to carry out our study as our research hopefully helps to replenish existing knowledge gap. In the study, we have used cross-sectional regression analysis for 30 Asian countries where data were collected for 1990-2000. Our dependent variable in our regression is average GDP per capita, which also defines growth. We have used two independent variables as main variables, trade volume and economic freedom index. Our analysis shows that the majority of the variables in the study have a positive significant relation to economic growth.
