Abstract
Systematic risk, or beta, measures stock price variability in the overall stock market. A considerable body of literature focuses on estimating beta. To the best of our knowledge, there is, however, a lack of definitive research on the impact of income elasticity of demand on stock market beta. This study is the first to examine this relationship using 659 publicly traded firms from 47 industries in South Korea from 2001 to 2020. To estimate the value of the stock market beta, we employ an econometric model with a fixed effects-two stage least squares approach and use industry concentration as an instrumental variable to deal with the endogeneity problem in the estimation. The overall objective of this study is to investigate the influence of income elasticity of demand on stock market beta.
