What drives productivity growth, how should we measure automation, and why does inflation remain persistent?
These are the questions explored in Chek Yin Choi's doctoral thesis, Input Market, Automation, and Inflation: Essays in Macroeconomics.
The thesis finds that:
• Better access to suppliers can increase productivity while also strengthening the position of the most productive firms.
• The way automation is defined has a major impact on conclusions about its labour market effects.
• Firms' decisions about when to adjust prices can help explain why inflation often remains elevated over time.
An interesting contribution to ongoing discussions about productivity, technological change and inflation.
Chek will defend his thesis on September 21.
