ABSTRACT We show that sovereign debt impairments can have a significant effect on financial markets and real economies through credit ratings channel. Specifically, we find firms reduce their investment reliance due to rising cost of capital following rating downgrade. identify these effects by exploiting exogenous variation in corporate agencies' ceiling policies, which require firms' remain at or below the country domicile.

We document a striking decline of about 50% in the maturity newly issued municipal bonds from 1920 to 2020. Changes credit risk and issuance costs cannot account for this decrease. Instead, legislative changes limiting banks' access reducing federal income taxes play more prominent role. analyze shocks financing needs generated by natural disasters find that shorter significantly impairs local government's ability react unexpected expenditure spikes. Critically, shortages during emergencies...

Abstract We show that credit rating agencies can influence political elections. find incumbent parties experience an increase in their vote shares following municipal bond upgrades. The evidence is consistent with affecting elections indirectly by expanding local governments’ debt capacity and directly through impact on voters’ perceptions of the quality politicians. To identify these effects, we examine election outcomes within neighboring counties exploiting exogenous variation ratings due...

This paper proposes a new approach to study how corporate policies change upon the replacement of CEO. We employ empirical Bayes simultaneous tests on executive fixed effects and find significant heterogeneity in their styles. Furthermore, we implement measure that explores differences styles between exiting CEO incoming comparison reveals before after turnover. Moreover, some changes are not immediate, so estimate fast firm policy converges equilibrium. For most part, our results...

While forest formations are officially supported a monitoring program, significant portion of biome (6.6 % or ~280,000 km²) constituted non-forest (NF) phytophysiognomies (e.g., savanna, grasslands, flood lands) still unmonitored. To address this information gap, PRODES NF system was...

We use confidential regulatory data to investigate how banking relationships affect banks' municipal bond holdings and their repercussions for issuers. provide causal evidence that banks favor holding bonds from issuers with whom they share relationships, regardless of the issuer's creditworthiness. These also have crucial implications They enhance issuance characteristics in good times act as a stabilizer during adverse times. Our study provides insights into central role play shaping arm's...

The Brazilian Amazon Satellite Monitoring Program (PRODES Amazonia) tracks forest loss in the but excludes about 6.6% ( ~ 280,000 km²) of non-forest vegetation (NF). Here we developed PRODES NF system to address this gap by adapting well-established methodology Amazonia. Initial findings from show that lost 10.46% 30,000 area, mainly last two decades, with estates Mato Grosso, Roraima, and Amapá being primary hotspots losses. Savannas were most affected (13.3% their extent). strongly...
