Using bank-level data from more than 30 countries, we find that natural disasters affect negatively the liquidity creation in the region. The cumulative effect over the three years following a disaster is economically significant, amounting to a total reduction of 4 % in the average liquidity generated. This impact is mainly channeled through the asset-side activities of banks. We also find heterogeneous impact of natural disasters on bank liquidity creation based on the size of banks, the magnitude of disasters and the income level of countries. Moreover, these effects are mainly observed when disasters strike on a large-scale. On the contrary, there is no significant difference depending on whether or not the disaster is climatic in origin. Additional tests show that foreign ownership of banks as well as monetary policy change do not qualitatively alter our primary findings. These results support bank regulation policies taking into the specificities of banks operating in environments prone to frequent natural disasters. Specifically, we recommend that central banks implement targeted regulatory measures such as stress-testing or resilience programs. As natural disasters are likely to increase in the coming years due to climate change, we suggest that microprudential policies be further strengthened and adapted to incorporate climate change considerations.</div></div>","PeriodicalId":47962,"journal":{"name":"Quarterly Review of Economics and Finance","volume":"100 ","pages":"Article 101959"},"PeriodicalIF":2.9,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143129718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each economic agent is concerned about the relative performance of other agents in terms of their average terminal wealth and intermediate consumption. The goal is to find the optimal investment–consumption strategy that is robust under the worst-case scenario of adverse probability measures. The competitive and ambiguity-averse agents can invest in an incomplete financial market composed of a risk-free asset, an equity index, and a single equity depicted by a class of generically non-Markovian multivariate stochastic covariance models, under which the market prices of risks hinge on a multivariate affine-diffusion factor process. The unified modeling framework includes some state-of-the-art stochastic covariance models as particular cases. A backward stochastic differential equation approach coupled with the martingale optimality principle addresses the robust non-Markovian stochastic differential game. Closed-form solutions are derived to the robust Nash equilibrium investment–consumption policies, the probability perturbation processes associated with the well-defined worst-case scenarios, and the corresponding value functions. Under certain technical conditions, we verify the admissibility of the solutions. Finally, we performed numerical experiments to showcase the impact of model parameters on robust investment–consumption strategies.</div></div>","PeriodicalId":47962,"journal":{"name":"Quarterly Review of Economics and Finance","volume":"100 ","pages":"Article 101949"},"PeriodicalIF":2.9,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143130273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A standard answer from the public choice literature points to non-benevolent states, emphasizing the importance of constraints on their power. This paper challenges this view by investigating the role of culture and examining whether the relative cost-efficiency of public versus private provision varies across cultures. We build a representative database for contracting choices of municipalities in Switzerland and exploit the discontinuity at the Swiss language border at <em>identical</em> actual set of policies and institutions to analyze the causal effect of culture on the choice of how public services are provided. We find that French-speaking border municipalities are 60% less likely to contract with the private sector than their adjacent German-speaking counterparts. Technical dimensions are much smaller by comparison and their effects do not vary with culture, ruling out cultural bias in municipality choices. We further document that public provision, compared to private provision, increases cost-efficiency within French-speaking Swiss municipalities. These results resonate with the literature emphasizing that public bureaucracies are mission-oriented organizations whose organizational efficiency is enhanced through mission matching, but they also unveil that this mission matching is culturally determined.</div></div>","PeriodicalId":47962,"journal":{"name":"Quarterly Review of Economics and Finance","volume":"99 ","pages":"Article 101899"},"PeriodicalIF":2.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143152262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also show that the influence of largest shareholders on corporate risk-taking is conditional on shareholder identity; whereas family and government control is associated with lower corporate risk-taking, foreign control has the opposite influence. Finally, our results show that when the two largest shareholders are families, they align their interests to support conservative decisions and that when the largest shareholder is a family but the second is an institutional investor, contesting control attenuates suboptimal risk policies. Our results contribute to the literature by reporting evidence to disentangle the heterogeneity within blockholders and the bivalent relationship between controlling and non-controlling large owners.
