Finance Leases: In the Shadow of Banks

Review of Finance 2022 26(3), 721-749 open access
By analyzing a hand-collected transaction-level dataset on the finance leases of China’s public firms for the period 2007–19, this article sheds light on China’s leasing market, the second largest in the world. We find that banks use their affiliated leasing firms to provide credit to clients in order to circumvent the government’s targeted credit tightening policy. In contrast to conventional view of regulatory arbitrage, our evidence shows that, rather than hiding risk and gambling for profit, banks-affiliated leasing firms have prudent risk control and efficient pricing. These bank-affiliated institutions are used by banks to play strategic role in relationship banking. Moreover, the ownership of the lessor also matters for the financing choice of the lessee.

Speed of convergence to market efficiency for NYSE-listed foreign stocks

Journal of Banking & Finance 2010 34(3), 594-605
This paper contributes to the cross-listing literature by documenting the speed of convergence to market efficiency for foreign stocks listed on the NYSE. We find that, on average, it takes 30–60minutes for a foreign stock to achieve market efficiency. For a comparable US stock, it takes only 10–15minutes. The significant difference between foreign and US stocks remains robust when the speed is measured by the number of transactions rather than in calendar time. After relevant firm characteristics are controlled for, the time that it takes for foreign stocks to reach efficiency is significantly negatively related to the quality of their home country institutions. We find that one possible channel through which institutions affect the speed is through their impact on information asymmetry.

The Effect of Financial Resources on Fertility: Evidence from Administrative Data on Lottery Winners

Journal of Labor Economics 2026 open access
This paper utilizes wealth shocks from winning lottery prizes to examine the causal effect of financial resources on fertility. We employ extensive panels of administrative data encompassing over 0.4 million lottery winners in Taiwan and implement a triple-differences design. Our analyses reveal that a substantial lottery win can significantly increase fertility, the implied wealth elasticity of which is around 0.06. Moreover, the primary channel through which fertility increases is by prompting first births among previously childless individuals. Finally, our analysis reveals that approximately 25% of the total fertility effect stems from increased marriage rates following a lottery win.

Windfall gains and stock market participation: Evidence from shopping receipt lottery

Journal of Banking & Finance 2025 172, 107378 open access
This paper utilizes receipt lotteries in Taiwan, along with comprehensive administrative data, to examine the effect of cash windfalls on stock market participation and portfolio diversification, which can help us understand whether wealth levels serve as the explanation for the limited participation and under-diversification puzzles in stock markets. The results indicate that each million TWD (approximately 33,000 USD) windfall gain from winning receipt lotteries increases the probability of stock market participation by 1.09 percentage points. This effect is primarily driven by individuals who were not participating in the stock market prior to winning. For existing participants, each million TWD windfall increases the total value of stocks by 142,552 TWD, attributed to both an increase in their number of shares and higher average prices of the stocks they hold. Additionally, we find that individuals do not significantly diversify their portfolios after winning the lottery, suggesting that wealth level is not the primary reason for under-diversification.
