Matching Algorithm

less than 1 minute read

Published:

This is a matching simulation using Deferred Acceptance algorithm for the real-world scenario of random divorce and rematching. Results are evaluated by metrics including fairness between genders, average matching rank (of boys, girls and total) as well as matched pairs and blocking pairs. Seminar Presentation codes

Impulse Response of Economy Policy Unstability Dynamics to Monetary Policies: VAR Model Analysis

1 minute read

Published:

The study investigates the impact of monetary policy on economy policy uncertainty with VAR for time series to discuss the policy implications for China. Results show that EPU (Economic Policy Uncertainty) responses the most strongly to itself and the impact lasts the shortest, showing that the EPU of last period has the most important influence to EPU of the current period. EPU responses least strongly to the currency amount but the influence continue the longest. Fullwork codes

Does Digitalization Spillover Negatively Influence the Economy? Empirical Evidence from Japan

1 minute read

Published:

This paper investigates impacts of digitalization development and digitalization spillover on economic performance, using PCA and OLS regression with fixed effects. Results from OLS regressions with fixed effects show that in general, digitalization development positively influences the overall prefectural economic behavior, but the spillover effect negatively impacts overall production and production per capita. Population aging and geographical closeness to countries with advanced digitalization worsen the negative influences of the spillover effect, but entertainment and life-related service industry development mitigate instead.

The Impact of Housing Prices on Family Stability in China

Published:

This research investigates how changes in housing prices influence divorce rates, using a policy shift in China as a natural experiment. The study employs a Regression Discontinuity Design (RDD) based on a 2010 policy that reduced taxes and down payments for small housing units (≤ 90m²). Results indicate that the policy indirectly affected divorce rates through its impact on housing prices. Although the policy increased housing wealth, it introduced new dynamics in marital stability. The analysis suggests that macroeconomic conditions, such as housing prices, play a significant role in marital decisions.Proposal Proposal Slides Empirical Results Slides

Soda Tax, Health Outcomes and Taxation Analysis in Mexico (Joint Work with Oscar Galvez-Soriano and George Chou)

Published:

This research examines the health effects of sugar-sweetened beverages (SSBs) and the 2014 soda tax in Mexico, introduced to mitigate consumption and improve public health. It highlights the substitution between water and SSBs, driven by limited access to clean water in Mexico. Despite mixed research findings, the tax led to a 6% decrease in SSB purchases, particularly among low-income households. The study also explores the ad valorem nature of the tax, its advantages in targeting lower-priced products, and its regressive impact on low-income individuals. The research aims to contribute by examining soda and water demand in Mexico and comparing the regressiveness of the tax to wealthier countries like the UK and the US. Brief

Schooling, Internship and Human Capital

Published:

This research explores the trade-offs between internships and education in the context of the Ben-Porath human capital model. It examines how individuals allocate their time to accumulate both general and industry-specific human capital to maximize their lifetime earnings. Internships offer industry-specific experience, while education provides general knowledge. The study also highlights how different industries value these two types of human capital, and how individuals optimize their time investment based on wage rates, costs of education and internships, and the productivity of each. By understanding this balance, the research aims to shed light on the decision-making processes of individuals as they navigate schooling and internships, contributing to broader discussions on labor market outcomes and human capital accumulation. slides for Oct 18 Presentation
