Macroeconomic Effects from Sovereign Risk vs. Knightian Uncertainty

Abstract
This paper compares macroeconomic effects of Knightian uncertainty and risk using policy shocks for the case of Italy. Drawing on the ambiguity literature, I use changes in the bid-ask spread and mid-price of government bonds as distinct measures for uncertainty and risk. The identification exploits the quasi-pessimistic behavior under ambiguity-aversion and the dealer market structure of government bond markets, where dealers must quote both sides of the market. If uncertainty increases, ambiguity-averse dealers will quasi-pessimistically quote higher ask and lower bid prices – increasing the bid-ask spread. In contrast, a pure change in risk shifts the risk-compensating discount factor which is well approximated by the change in bond mid-prices. I evaluate economic effects of the two measures within an instrumental variable local projection framework. The main findings are threefold. First, the resulting shock time series for uncertainty and risk are uncorrelated with each other at the intraday level, however, upon aggregation to monthly level the measures become correlated. Second, uncertainty is an important driver of economic aggregates. Third, macroeconomic effects of risk and uncertainty are similar, except for the response of prices. While sovereign risk raises inflation, uncertainty suppresses price growth – a result which is in line with increased price rigidity under ambiguity.

Economic Preferences for Risk-Taking and Financing Costs
Manthos D. Delis, Iftekhar Hasan, Maria Iosifidi, Chris Tsoumas
Journal of Corporate Finance,
June
2023
Abstract
We hypothesize and empirically establish that economic preferences for risk-taking in different subnational regions affect firm financing costs. We study this hypothesis by hand-matching firms' regions worldwide with the corresponding regional economic risk-taking preferences. We first show that higher regional risk-taking is positively associated with several measures of firm risk and investments. Subsequently, our baseline results show that credit and bond pricing increase when risk-taking preferences increase. For the loan of average size and maturity a one-standard-deviation increase in regional risk-taking increases interest expense by $0.54 million USD. We also find that these results are demand (firm)-driven and stronger for firms with more local shareholders.

The Place-based Effects of Police Stations on Crime: Evidence from Station Closures
Sebastian Blesse, André Diegmann
Journal of Public Economics,
March
2022
Abstract
Many countries consolidate their police forces by closing down local police stations. Police stations represent an important and visible aspect of the organization of police forces. We provide novel evidence on the effect of centralizing police offices through the closure of local police stations on crime outcomes. Combining matching with a difference-in-differences specification, we find an increase in reported car theft and burglary in residential properties. Our results are consistent with a negative shift in perceived detection risks and are driven by heterogeneous station characteristics. We can rule out alternative explanations such as incapacitation, crime displacement, and changes in police employment or strategies at the regional level. We argue that criminals are less deterred due to a lower visibility of the local police.
