This paper measures the urban shape of Chinese prefecture-level cities and examines the impacts of its fragmentation on local innovation activity. Using a harmonized satellite nightlight dataset from 1999 to 2021, we delineate urban areas as polygons formed by adjacent bright grids at night. We decompose changes in a city's urban shape into two components: the dispersion of individual polygons, and the fragmentation characterized by the growing spatial separation between these polygons. Our empirical analysis reveals that deteriorating urban shape, which typically results in longer commutes for individuals to meet, is associated with fewer local patent grants, with urban fragmentation being the primary driver. Mechanism analysis reveals that intensified urban fragmentation disproportionately impedes collaborative innovation, primarily by elevating communication costs within inventor teams. These findings highlight the pivotal role of optimized urban spatial structures in fostering face-to-face interactions and knowledge spillovers essential for innovation ecosystems.

This study investigates the evolution of wealth polarization throughout the 21st century, using data from the Chinese Household Income Project (CHIP) and the Top Incomes in China (TIC) database. Our findings reveal a significant increase in polarization from 2002 to 2013, followed by a period of stabilization and signs of moderation by 2018. Decomposing polarization into alienation and identification, we observe that alienation (between group inequality) continues to rise from 2002 to 2018, while identification (within group cohesion) increases until 2013 but declines thereafter. The underrepresentation of rich households leads to an underestimation of alienation and an overestimation of identification. While these counterbalancing effects contribute to higher polarization levels, they do not alter the trend during the period. However, as the mitigating effect on identification diminishes and the growing effect on alienation intensifies, it suggests potential challenges in accurately tracking future changes in wealth polarization using survey data.

This paper exploits the reform of China's Budget Law, which restricts the rollover of fiscal surplus across years, to examines the impact of UILI (use-it-or-lose-it) budget rules on year-end spending spikes. We analyze the universe of public procurement contracts from 2014 to 2021 and develop a method to assess contract quality. We show substantial surges in procurement contracts at the end of the year, which are more likely to be of low quality. The difference-in-difference model indicates that after the reform, local governments award 25.8 % more procurement contracts and double spending on procurement in the last month of the year. The year-end spending surges concentrate on goods and construction projects procurement, high-value contracts, and favor local suppliers. It is likely that UILI rules intensify budgetary uncertainty embedded in hierarchical allocation of fiscal fund.

This paper examines how global monetary policy shocks (MPS) transmitted through trade networks affect supply chain adaptation of Chinese firms. When exposed to higher supplier-side MPS, firms experience significantly higher separation rates and lower foreign entry rates. Our findings remain robust across a range of alternative MPS measures. In response, firms shift their sourcing from high-interest-rate countries to low-interest-rate countries, but they do not re-shore. We show that trade credit and price adjustment by suppliers are important for explaining the restructuring. The disruption is more likely driven by customer decisions. Moreover, heterogeneities show that firms with stricter credit constraints are more sensitive to MPS, while longer-duration supply chain relationships show greater resilience. The supply chain adaptation induced by MPS also leads to adverse real economic outcomes for imports, exports, and profitability.

Using staggered-implemented Incorporating-Counties-into-Prefectures Policy as an exogeneous shock, this paper explores how urbanization promotes entrepreneurial activities. A battery of specifications verifies a positive effect of ICIP policy on firm entry. Mechanism analysis implies expanded market demand, increased supply of higher-quality production factors, and improved institutional environment help explain the phenomenon. Unlike market-driven urbanization in Western countries, this paper emphasizes the role of government-led urban expansion policies in developing nations, highlighting their potential to accelerate urbanization, industrial upgrading, and entrepreneurships in underdeveloped regions.

Food recall is an important measure in food safety management. This study investigated the impact of food recall strategies on repairing consumer trust in food products. We examined three food recall strategies (voluntary, mandatory, and no recall) adopted by firms after discovering food defects. We designed a scenario-based experiment and used difference-in-differences (DID) models to analyze how these strategies influence consumer trust repair. Furthermore, we examined the moderating roles of trust violation type (competence vs. integrity) and consumer trust disposition. Our results show that both voluntary and mandatory recalls significantly enhance consumer trust in terms of competence, benevolence, and integrity. These findings contrast with previous studies and common consensus that food recalls tend to damage consumer perceptions. We also find that voluntary recalls are more effective than mandatory recalls for repairing consumer trust. Additionally, trust violation type and trust disposition moderate the effects of recall strategies on trust repair. These findings can help firms adopt the most effective trust repair strategies after discovering food defects, and assist regulators in restoring consumer confidence in food quality and safety.

This paper examines the role of background ambiguity in intertemporal choice. Using natural variation in background ambiguity from the uncertainty surrounding summer vacation and a within-subject difference-in-differences experimental design, we find that individuals tend to avoid allocating money to the summer period, leading to nonmonotonic changes in discount rates. To investigate the underlying mechanism, we exogenously increase summer planning efforts and find that this reduces perceived background ambiguity about summer and increases individuals' willingness to allocate money to that period. These findings suggest that background ambiguity plays an important role in shaping intertemporal preferences.

Unlike central banks in developed economies, the People's Bank of China (PBC) does not explicitly use forward guidance but rather provides explanatory information about monetary policy. The PBC has mainly used quarterly written reports and non-periodic oral channels to communication with the market, but there are significant differences in the institutional objectives and textual structures of these two types of communication. This paper investigates the real effects of the PBC's narrative on the macroeconomy. Our results show that the PBC's policy-related information can also guide inflation expectations and have a direct impact on the macroeconomy. The different macroeconomic effects between oral communication and written communication lies in their differences in timeliness, semantic complexity and ambiguity. Meanwhile, such explanatory communication can help the public understand policy stance, resist the negative impact of economic policy uncertainty, and thereby enhance monetary policy effectiveness. Finally, we find that oral communication has an increasingly significant impact on inflation expectations through variance decomposition.

We investigate political budget cycles in prefecture-level cities in China by leveraging cross-province variation in the timing of the Provincial Congress of the Communist Party, which is the most significant event for promoting and reappointing prefecture leaders. Our findings reveal strong evidence of a cyclical pattern, characterized by an increase in government spending leading up to the Congress, followed by a decrease afterward. This trend is particularly pronounced for infrastructure spending, which is a crucial driver of economic growth in China. Additionally, we examine China's multi-layer government hierarchy and explore heterogeneity across prefectures. Our analysis shows that these cycles are especially evident when promotion opportunities for prefecture leaders are most prominent. In terms of revenue sources, we do not observe significant cyclical patterns for in-budget revenues; however, we do find evidence of cycles in revenues from land sales, a vital source of off-budget revenues. Our study contributes to the literature by examining both the size of government and the allocation of public funds in order to uncover distinct political budget cycles at the prefecture level in China and highlighting the vertical incentives within the multi-layer government hierarchy.
