On June 14, Maksim Obrizan, a Professor of the Kiev School of Economics, gave a presentation entitled “The Impact of War on Happiness: The Case of Ukraine” at ISET. According to Mr. Obrizan, his work was influenced by cases and papers described in Frey and Stutzer (2002) and Stutzer and Frey (2012), and the impact of wars according to Blattman and Miguel (2010). This has become a particularly poignant topic for Professor Orbizan, as more than 100 Ukrainian soldiers have committed suicide since coming off the front line in the ongoing war against Russian-backed separatists. Previous papers on war and happiness suggest that in 44 countries, the intensity of the war reduces happiness (Welsh 2008).

On Thursday June 9th, Professor Bruce Boghosian of Tufts University gave a presentation entitled "The Statics and Dynamics of Wealth Distribution", a fascinating topic which detailed the use of an innovative approach to investigate inequality dynamics. Professor Boghosian first reviewed the history of measuring inequality, and discussed the works of well-known scholars of the field such as Pareto, Gibrat, Lorenz, and Gini, and then shared his own fascinating research with the audience. Though the mathematical rigour of the models was interesting, the results were fascinating; Boghosian showed that under certain conditions (when total wealth is unchanged and transactions between economic agents are conducted with few mistakes), societies are consistently prone to wealth concentration and Gini coefficient trends increase.

Congestion in electricity transmission systems is a common problem all around the world, Georgia included. Two types of congestion are observed in the power sector; physical and economic. Physical congestion occurs when a transmission system is not adequate to supply an increasing amount of electricity. Economic congestion appears when prices in one region are different from those in another region, while cheaper electricity cannot be sold to the region at high prices.

On Tuesday, May 24, Dr. David Ubilava from the University of Sidney gave a presentation entitled "The El Niño Southern Oscillation and Economic Growth”. Dr. Ubilava started the presentation with the definitions of such phenomena such as climate anomalies and weather and emphasized the importance of weather as a factor in agricultural production.

Looking down from the famous cross-path of the Georgian Military Highway, you will notice a beautiful little lake that was not there six years ago. The lake is a small reservoir that supplies power to the 8 MW Aragvi HPP. On May 19, the ISET community and guests from professional circles in the energy sector heard the story behind this hydropower plant in a seminar entitled “Small Hydropower – what’s special about it and how to implement it?” delivered by Hanness Posch, a civil engineer and entrepreneur working on hydropower projects in Georgia.
