We document novel evidence on the spillover effect of a corporate control regulation on local mortgage markets. We find that banks directly targeted by the Sarbanes-Oxley Act (SOX) to rectify their internal control weaknesses reduce mortgage originations following the regulation’s enactment. This causes mortgage credit to be reallocated toward other banks in the same local markets: while competing public banks expand lending to safer borrowers, private banks increase lending toward risky applicants. Consequently, loans originated by private banks in spillover counties report higher default rates. (JEL E51, G21, G38)

We exploit an exogenous change in the coverage of insured deposits following the passage of the Emergency Economic Stabilization Act (2008) to investigate the impact of deposit insurance on the volume, composition and quality of credit union lending. Using a difference-in-difference approach, we find changes in the volume, composition and riskiness of credit union lending. Specifically, we find that affected credit unions increase total and unsecured lending, leading to a decline in loan quality. Overall, our results suggest that an increase in the maximum coverage of insured deposits induces credit unions to lend more at the expense of loan quality.

A chronic helminth infection can alter host immune response and affect malaria infection. We conducted a systematic review and meta-analysis to find the impact of anthelmintic treatment on malaria prevalence, incidence, and parasitemia. Nine and 12 electronic databases were searched on 28 th July 2015 and 26 th June 2020 for relevant studies. We performed meta-analysis for malaria prevalence, incidence, parasitemia, and a qualitative synthesis for other effects of anthelmintic treatment. Seventeen relevant papers were included. There was no association between anthelmintic treatment and malaria prevalence or change of parasitemia at the end of follow up period (pooled OR 0.93, 95% CI: 0.62, 1.38, p-value=0.71 and SMD -0.08, 95%CI: -0.24, 0.07, p-value=0.30 respectively) or at any defined time points in analysis. Pooled analysis of three studies demonstrated no association between malaria incidence and anthelmintic treatment (rate ratio 0.93, 95%CI: 0.80, 1.08, p-value=0.33). Our study encourages anthelmintic treatment in countries with high burden of co-infections as anthelmintic treatment is not associated with change in malaria prevalence, incidence, or parasitemia.
