Intuitively core inflation is understood as a measure of inflation where noisy price movements are avoided. This is typically achieved by either excluding or downplaying the importance of the most volatile items. However, some of those items show high persistence, and one certainly does not want to disregard persistent price changes. The non-equivalence between volatility and (the lack of) persistence implies that when one excludes volatile items relevant information is likely to be discarded. Therefore, we propose a new type of core inflation measure, one that takes simultaneously into account both volatility and persistence. The evidence shows that such measures far outperform those based on either volatility or persistence. The latter have been advocated in the literature in recent years.
Fintech has become one of the most popular topics among policymakers and experts. It usually comes with the qualifier "disruptive". Thus, the hype is easy to understand: fintech would upend the financial system due to its disruptive nature, as it would allow financial services to be completed faster, cheaper, and more efficiently. Indeed, many have predicted that the remittances market was on the verge of being disrupted as remittances are considered too costly while remittance service providers inefficient, opaque, and outdated. Therefore, there seems to be no better setting for assessing the allegedly disruptive effects of fintech. Against that background, this paper investigates how those predictions have fared so far. Contrary to expectations, it found that instead of disrupting incumbents fintechs have increasingly been entangled with them. Therefore, not only there is no evidence of disruption, but it is unlikely to occur in the foreseeable future. Even so, the paper argues that fintechs play an important role in the remittances market.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
