Changing One's Mind when the Facts Change: Incentives of Experts and the Design of Reporting Protocols

Review of Economic Studies 2007 74(4), 1175-1194 open access
Experts often collect and report information over time. What reporting protocol elicits the most information? Here, a principal receives reports sequentially from an agent with privately known ability, who observes two signals about the state of the world. The signals differ in initial quality and, unlike previous work, differ in quality improvement. The paper finds that “mind changes” (inconsistent reports) can signal talent if a smart agent improves faster. Also, sequential reports dominate when the principal's decision is very sensitive to information; a single report dominates if the mediocre agent's signals improve faster or the agent is likely mediocre.

Government connections and financial constraints: Evidence from a large representative sample of Chinese firms

Journal of Corporate Finance 2015 32, 271-294 open access
We examine the role of firms' government connections, defined by government intervention in CEO appointment and the status of state ownership, in determining the severity of financial constraints faced by Chinese firms. We demonstrate that government connections are associated with substantially less severe financial constraints (i.e., less reliance on internal cash flows to fund investment), and that the sensitivity of investment to internal cash flows is higher for firms that report greater obstacles to obtaining external funds. We also find that those large non-state firms with weak government connections, likely the engine for innovation in the coming years in China, are especially financially constrained, due perhaps to the formidable hold that their state rivals have on financial resources after the ‘grabbing-the-big-and-letting-go-the-small’ privatization program in China. Our empirical results suggest that government connections play an important role in explaining Chinese firms' financing conditions, and provide further evidence on the nature of the misallocation of credit by China's dominant state-owned banks.

Discontinuous Distribution of Test Statistics Around Significance Thresholds in Empirical Accounting Studies

Journal of Accounting Research 2025 63(1), 165-206 open access
ABSTRACT Examining test statistics from articles in six leading accounting journals, we detect discontinuities in their distributions around conventional significance thresholds ( p‐ values of 0.05 and 0.01) and find an unusual abundance of test statistics that are just significant. Further analysis reveals that these discontinuities are more prominent in studies with smaller samples and are more salient in experimental than in archival studies. The discontinuity discrepancy between experimental and archival studies relates to several proxies for researcher degrees of freedom. Nevertheless, this evidence does not imply that experimental research is more prone to questionable research practices than archival studies. Overall, our findings speak to the concern of whether accounting researchers could exercise undisclosed discretion to obtain and report statistically significant results. Based on our results, a healthy skepticism of some just‐significant test statistics is warranted.

Asset Pricing with Cohort‐Based Trading in MBS Markets

Journal of Finance 2022 77(6), 3249-3287 open access
ABSTRACT Agency mortgage‐backed securities (MBSs) with diverse characteristics are traded in parallel through individualized specified pool (SP) contracts and standardized to‐be‐announced (TBA) contracts with delivery flexibility. This parallel trading environment generates distinctive effects on MBS pricing and trading: (i) Although cheapest‐to‐deliver (CTD) issues are present in TBA trading and absent from SP trading by design, MBS heterogeneity associated with CTD discounts affects SP yields positively, with the effect stronger for lower‐value SPs; (ii) high selling pressure amplifies the effects of MBS heterogeneity on SP yields; and (iii) greater MBS heterogeneity dampens SP and TBA trading activities but increases their ratio.

Implicit guarantees and the rise of shadow banking: The case of trust products

Journal of Financial Economics 2023 149(2), 115-141 open access
Implicit guarantees provided by financial intermediaries are a key component of China's shadow banking sector. We show theoretically that project screening by intermediaries, accompanied by their implicit guarantees to investors, can be the second-best arrangement and mitigate capital misallocation that favors state-owned enterprises (SOEs). Using a dataset of trusts’ investment products, we find, consistent with our model, that ex ante expected yields reflect borrower risks and implicit guarantee strength, and risk sensitivity is reduced by strong guarantees. Regulations in 2018 restricting implicit guarantees lead to a weaker relationship between yield spread and guarantee strength, and more credit rationing of non-SOEs.
