    •    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.
