Abstract

The labor share fluctuation has been widely scrutinized recently. Is the labor share of income falling as many have argued over the last few years? How do we measure labor income when the economy isopulated with those self-employed? What are the consequences of falling labor income? Rising inequality? Widespread adoption of robots? There are many methodological as well as empirical discussion to be addressed regarding how to measure labor income share and the cause and consequence of changing labor income share over time. Thisroject bravely titled “the labor income share and fluctuations” attempts to clarify some recent research on the related topic and analyzes the changing trend in the labor share in South Korea. Specifically, in Chapter 1, Facundoiguillem reviews the rich literature on the labor share over the last thirty years. He carefully examines the dispute over the fact that the labor share is globally declining, chronically reviewing the calculation of labor share, the associated criticism, andotential implications. In Chapter 2, Marco Diietro estimates a model with technology choice using South Korean data and shows that this model does a fairly good job of matching data moments in comparison to a standard mode with Cobb-Douglasroduction technology and a model with short- and long-run CES only. This model also does a good job of replicating the behavior of the labor share of income at short to medium-run frequencies. Finally, in Chapter 3, Sun-Bin Kim analyzes the changing trend of the labor share in South Korea and examines how much the decrease in the relativerice of investment goods can explain the changing labor share.
