After its introduction in 1978, Data Envelopment Analysis (DEA) has instantly been recognized as a useful methodology for measuring the relative efficiency of different entities, called Decision Making Units (DMUs), given multiple criteria. Up until nowadays, the popularity of DEA has been growing and a significant number of bibliographical items was published, reporting on both theoretical and empirical results. However, the main applicative area of DEA remained the performance measurement in economics and business. On the 40th anniversary of DEA, the aim of this paper is to present the DEA bibliography of Croatian scientists (up until June 2018). We consider six main categories of DEA-related publications, followed with key statistics and an overview of keywords and research areas. The whole list of DEA-related publications used in this analysis is published online. We believe this research will shed light on the state of DEA in Croatian science and motivate future researches.

We utilize two waves of the National Income Dynamics Study in South Africa to estimate the returns to education in 2010 and 2012. We find that during this time period the returns to education were approximately 18% per year of education and that the returns were higher for females relative to males and higher for those living in urban relative to rural areas. The policy implications include a suggestion to continue investment in educational infrastructure, especially in rural areas, so as to increase the returns to education in those areas.

Social media today represent a global community of different nationalities - the size of China in terms of population, and social networking sites are online venues where users can create and post content. Social networks have also become one of the most popular ways for people to socialize, connect with friends and family, purchase items and gather relevant information about current and political topics and views. The most popular and biggest social network is Facebook and its influence in every pore of our society is evident, e.g. potential misuse of its user’s data in different purpose including manipulation in political purposes. This paper will also cover the findings of a survey conducted in Croatia and Serbia about the perception of social media and social networks as a source of gathering relevant information.
Applying an extended IS-MP-AS model (Romer, 2000), this paper shows that real depreciation of the euro raises real GDP in Kosovo and that a lower real lending rate in the euro area, a higher real GDP in Germany, a lower real oil price, or a lower expected inflation rate would help increase real GDP. More government deficit spending as a percent of GDP does not affect real GDP.

The study examines firm’s investment behaviour sensitivity to cash flow before, during and after the recent global financial crisis using the data of 28 firms listed on the Nigerian Stock Market during the period from 2001 to 2012. The contribution of the study to the existing literature rests on using financial crisis as basis for classifying firms as either financially constrained or unconstrained. Employing the panel data and instrumental variable estimation techniques, the study finds that firms’ investment behaviour sensitivity to cash flow was higher during the financial crisis than before or after the financial crisis. In other words, Nigerian firms were highly financially constrained during the last financial crisis.
