I am currently a Ph.D. candidate in economics at the University of Missouri and actively seeking job opportunities for the 2023-24 academic year, available for interviews. My primary research interests are in Applied Microeconomics, with a specific focus on Energy Economics and Industrial Organization. My research involves understanding how firms respond to environmental changes, including cost shifts, competitors' price change, and alterations in policies or market structures. Aside from my academic pursuits, I possess strong proficiency in working with large datasets, including data cleaning, summarization, visualization, and statistical modeling. I am enthusiastic about opportunities in both data science and economics.

Working Paper

• Unraveling Price Stickiness: Evidence from Daily Gasoline Prices in Seoul, Korea Job Market Paper
  Stickiness in retail prices has been well-documented empirically, while economic explanations of the phenomenon are still debated in macroeconomics and industrial organization. This study investigates price stickiness using daily prices of gasoline stations in Seoul, Korea. It finds that stations change prices infrequently and that the infrequent adjustments follow both state-dependent and time-dependent patterns. Stations with greater local market power tend to favor the time-dependent pricing rule, resulting in price changes at regular intervals. These empirical findings contribute to our understanding of price stickiness, offering insights from both the perspectives of industrial organization and macroeconomics.
