Overall, our study is the first to demonstrate that nightlight data constitutes a relevant proxy for economic activity in SIDS, a group of territories characterized by a scarcity of economic data.

We hypothesize that enterprises in civil law countries, where legal frameworks are codified and regulations are prescriptive, are more likely to invest in new product/service innovation due to the predictability and stability of their legal environments. Conversely, enterprises in common law countries, with their flexible and adaptive legal systems, are expected to prioritize process innovation, driven by the need to optimize operations and navigate regulatory changes more easily. Using data from the World Bank Enterprise Surveys covering private enterprises in 113 countries between 2010 and 2024, we find strong evidence supporting these hypotheses. Enterprises in civil law countries show a higher propensity for product/service innovation, while those in common law countries focus more on process innovation.

By leveraging a quasi-natural experiment derived from publicly disclosed information of listed commercial banks, we employ a staggered DID model to investigate the impact of bank transparency on liquidity hoarding and its transmission channels.

This is mainly because disclosure enhances public trust in banks, thereby lowering banks’ interest expense on customer deposits. At the same time, banks increase the issuance of corporate loans and mortgages, and reduce holdings of trading financial assets. The inhibitory effect of information disclosure on liquidity hoarding is more pronounced in the following three types of banks: high-risk banks, banks holding high liquidity assets, and banks located in provinces with stronger financial regulatory intensity.</div></div>","PeriodicalId":11468,"journal":{"name":"Economics Letters","volume":"254 ","pages":"Article 112419"},"PeriodicalIF":2.1,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More specifically, our findings suggest that remittances are growth-friendly only when the country is experiencing rapid economic growth. During normal periods, changes in remittances have little to no impact or are counterproductive.
