    Political Background and Household Financial Asset Allocation in China
    (Taylor & Francis (Routledge), 18/01/2021) Ge Y; Chen H; Zou L; Zhou Z
    Political background is an important factor in determining the household economic behavior. Using 2014–2018 households panel data from the China Family Panel Studies (CFPS), we investigate the effects of political background on China’s household asset allocation behavior. We find that political background has a significant positive impact on the financial market participation. Mediation analysis indicates that political background leads to higher household wealth, better social capital, and fewer credit constraints, thus promotes households investments. Further analysis shows that the marginal impact of political background on household investment behavior is more significant in Eastern and urban areas. Our results contribute to the existing literature on the relationship between the political background and the household investment behavior, also enhancing the understanding of the household portfolio heterogeneity.

    Reprocessable Epoxy-Anhydride Resin Enabled by a Thermally Stable Liquid Transesterification Catalyst.

    Introducing dynamic ester bonds into epoxy-anhydride resins enhances the reprocessability of the crosslinked network, facilitated by various types of transesterification catalysts. However, existing catalysts, such as metal salts and organic molecules, often struggle with dispersion, volatility, or structural instability issues. Here, we propose to solve such problems by incorporating a liquid-state, thermally stable transesterification catalyst into epoxy resins. This catalyst, an imidazole derivative, can be uniformly dispersed in the epoxy resin at room temperature. In addition, it shows high-temperature structural stability above at least 200 °C as the synergistic effects of the electron-withdrawing group and steric bulk can be leveraged. It can also effectively promote transesterification at elevated temperatures, allowing for the effective release of shear stress. This property enables the thermal recycling and reshaping of the fully crosslinked epoxy-anhydride resin. This strategy not only enhances the functionality of epoxy resins but also broadens their applicability across various thermal and mechanical environments.
