We generalize the parametric quadratic-Gaussian framework employed by Bojilov and Galichon (2016) and Lindenlaub (2017), which relies on joint normality of observed characteristics. We allow unrestricted distributions of characteristics and show identification of the production technology and the equilibrium wage and matching functions using optimal transport theory. Given identification, we propose efficient, consistent, and asymptotically normal sieve estimators. We revisit Lindenlaub’s empirical application and show that, between 1990 and 2010, the U.S. economy experienced much larger technological progress favoring cognitive abilities than the original findings suggest. Furthermore, our flexible model specifications provide a significantly better fit for patterns in the evolution of wage inequality. 2026-07-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/218430 Title: Buy-sell imbalances on and around round numbers in cryptocurrencies Authors: Han, SeungOh; Lee, Albert J. Abstract: This paper examines buy-sell imbalances in the cryptocurrency market, focusing on prices on and around round numbers. Using a high-frequency intraday dataset for 18 cryptocurrencies, we find abnormally high buy (sell) pressure just below (above) round number prices, consistent with the existence of psychological biases. Further, we show that cryptocurrencies with higher mining activities, higher average price, and larger average trade size exhibit smaller imbalances. Our findings contribute to the literature by exploring these effects and their implications for market efficiency in digital assets. 2026-07-01T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/218536 Title: Fixed-Smoothing Uniform Inference for Quantile Regression Authors: 윤정모 2026-06-23T00:00:00Z https://scholarworks.bwise.kr/hanyang/handle/2021.sw.hanyang/218286 Title: Inter- and Intra-generational Redistributive Effects of the National Pension System in Korea Authors: 전영준 2026-05-29T00:00:00Z
