HUMAN CAPITAL AND EMPLOYMENT SUCCESS: THE ROLE OF PERSONALITY TRAITS by Savelieva Zoia A thesis submitted in partial fulfillment of the requirements for the degree of MA in Economic Analysis Kyiv School of Economics 2020 Thesis Supervisor: Professor Kupets Olga Approved by ___________________________________________________ __________________________________________________ __________________________________________________ __________________________________________________ Date ___________________________ Kyiv School of Economics Abstract HUMAN CAPITAL AND EMPLOYMENT SUCCESS: THE ROLE OF PERSONALITY TRAITS by Savelieva Zoia Thesis Supervisor: Professor Kupets Olga Over a long period of time IQ and educational levels were treated to be the main determinants of employment success. The aim of this study is to show that personality traits (patterns of thoughts, feelings, and behaviors) do play an important role in employment status, occupation position, and economic sector choice. Using cross-section data from the STEP survey of the urban working-age population in Ukraine we found out that emotional stability and openness to experience play a key role in explaining probability to be employed, occupy a managerial position, or being employed in a certain industry. Family background factors were shown to be a significant mediator of the relationship between personality traits and employment characteristics. The obtained results might be used for further policy decisions in pre-school, primary, secondary, and higher education as well as in workplace training programs. TABLE OF CONTENTS CHAPTER 1.
