Do economic incentives govern information diffusion in markets? Using international banks’ advisory activities in corporate takeovers as their source of private information, we show in supervisory data that banks with closer ties to the target, but not the acquirer, advisor trade profitably in the target’s stock prior to the deal announcement. This trading behavior is associated with a higher premium paid by the acquirer without compromising the deal success. As the incentives of informed traders are aligned only with those of the target shareholders, which are represented by the target advisor, our evidence suggests strategic information transmission among these banks.

This paper examines how political networks influence insider trading in China. Using biographical data to construct chairman–politician social networks, we find that firms with stronger political networks engage in significantly less insider trading. The effect is stronger for non-state-owned enterprises (non-SOEs) and for long-standing or high-ranking connections. The muted trading persists during periods when insiders possess valuable private information, including prior to M&A announcements and major policy events. The evidence suggests that personal political networks function as informal governance mechanisms that discipline managerial opportunism when formal governance through state ownership is absent.

We study the procurement patterns of non-listed firms and examine how these often-overlooked, yet pivotal players in global supply chains adjust their sourcing when they anticipate accountability for externalities beyond their organizational boundaries. Using granular customs data and a surprise information release about the German Supply Chain Due Diligence Act, product-level regressions reveal that importing firms are 3.5 percentage points less likely to source a product from countries where the relevant production sector exhibits elevated ESG-related risks, suggesting that firms tend to cut ties with higher-risk suppliers. The effects are concentrated among firms with well-diversified supplier networks for a product and higher profitability, suggesting they have the necessary flexibility to respond quickly to anticipated regulatory pressure. Our findings suggest that mandates requiring firms to incorporate broad sustainability considerations into their operational decisions may have limits, particularly for non-listed firms.

Drawing on detailed career and biographical data of Chinese politicians, this study builds a dynamic social network for all political elites in China and examines the selection process of provincial-level politicians. Using regression and tree-based machine learning techniques and leveraging individuals’ global centrality within political networks, we unveil the relative importance of economic performance, political networks, and career trajectory in determining the selection of provincial leaders. Our findings highlight the critical role of network embeddedness.

We investigate the relationship between county-level social capital in the U.S. and asymmetric earnings timeliness (accounting conservatism). We measure social capital by the strength of civic norms and the density of social networks in a community. We find that firms headquartered in regions with higher social capital have earnings that reflect bad news more quickly than good news. Two potential mechanisms driving this connection are evident in our findings. First, the positive link between social capital and asymmetric earnings timeliness is more pronounced in firms with weaker external oversight, suggesting that social capital compensates for weaknesses in these mechanisms by discouraging managers from delaying the recognition of bad news. Second, we illustrate that firms in high social capital regions are more likely to recruit senior executives with higher asymmetric earnings timeliness coefficients. This result implies a preference for managers who adopt more conservative accounting practices. We find similar results using an international sample of firms from 21 countries. Our findings offer new insights into how local social norms influence corporate financial reporting.

Climate policies do not operate in isolation but propagate through global production networks, affecting industries beyond national borders. This paper combines international input-output data with a granular instrumental variable approach to capture how foreign regulations transmit through upstream and downstream linkages. Distinguishing between market-based policies, non-market regulations, and technology support, the analysis shows that foreign climate policies can enhance domestic productivity, with effects shaped by industry characteristics and operating through technological adjustment along supply chains. The results underscore the importance of accounting for international spillovers when evaluating the economic impact of environmental regulation.
