However, with habit formation, the wealth effect outweighs the discouragement effect and induces an increase in LFP, resulting in a more significant decline in aggregate search intensity due to the expanded searcher pool.

Based on the results of the propensity score matching and difference-in-differences approach and mechanism analysis, SCF digitalization is found to inhibit corporate financial fraud by reducing a firm's relational transactions with its suppliers and customers.

When considering heterogeneities across types of debt, we observe that households adjust their spending faster in response to debt not associated with real estate assets. By exploiting explicit information on household credit constraints, we find no evidence suggesting that they play a significant role in shaping the debt-consumption nexus. We conclude that in a situation of high leverage and financial stress, debt overhang decreases household consumption.

This study uses China's Environmental Protection Tax (EPT) law as a quasi-natural experiment to explore whether and how such tax-based environmental regulations influence the productivity of heavily polluting firms. Using a difference-in-differences approach, we find that the EPT law has positively impacted firm productivity by fostering higher research and development investments and encouraging the substitution of labor with capital. The productivity-enhancing effect is more pronounced for state-owned enterprises, large firms, firms with fewer financial constraints, firms receiving more government subsidies, and firms operating in less competitive sectors.
