- This study empirically analyzes the impact of digital financial
inclusion on the industrial structure in China. The following are
four empirical findings from the multiple regression model. First,
digital financial inclusion is associated with a substantial impact
on industrial structure optimization. Second, three sub-levels of
digital financial inclusion have a significant positive impact on
industrial structure upgrading. Third, government spending and
the GDP per capita have positive impact on the optimization of the
industrial structure. The effects of educational development vary
across the regions. Fourth, digital financial inclusion in eastern
China has a stronger promoting effect on industrial structure
advancement.

- This paper examines the effects of disability on labor income
taxation by incorporating disability into Mirelees¡¯s (1971) model.
Both labor productivity and disability status are asymmetric
information and different across workers. Without disability,
optimal marginal labor income tax rates (MLITR) are
non-negative. However, the disability risk can lower the optimal
MLITRs, sometimes to negative values, because workers could
over-report their productivity and claim as disabled later. This
behavior becomes more relevant with smaller productivity gaps
across workers. This finding suggests that the disability risk can
reduce the MLITRs, as labor productivity is continuously
distributed in the real world.

This study demonstrates that it is possible to achieve sustained
excess returns in the cryptocurrency market by constructing
portfolios of cryptocurrencies. To this end, 126 cryptocurrencies
were divided into the blockchain and DeFi sectors, and long-only
or long/short portfolios were constructed based on strategies such
as price momentum, price-to-sales ratio, and revenue growth, with
market capitalization or fixed weightings applied in each sector. The
risk-adjusted relative returns of each portfolio were derived against
the S&P 500. The results showed that the blockchain sector exhibited
significant excess returns against the S&P 500 and risk-free rates
across all factors in long-only portfolios, while in the DeFi sector,
portfolios performance is not robust as in the blockchain sector. The
findings of this study suggest the necessity of setting investment
strategies that take into account the unique characteristics of each
cryptocurrency sector.
