The Unassuming Economist

From a paper by Liesel A. Ritchie, Susan L. Cutter, Nnenia Campbell, Melanie Gall:

“In the United States, segments of the population were suddenly and unexpectedly thrown into need during the COVID-19 pandemic and began to use food banks and other non-profit organizations providing food services. Here we examine the meaning of what we call the “new vulnerable.” The pandemic became a test of the entire food system, and clearly exposed the need for a re-examination of preparedness in the short run, and vulnerability and resilience in the long term. We explore whether the demographics associated with the drivers of vulnerability (e.g., ageism, racism, ethnocentrism) have changed. The lived experiences of vulnerable groups are defined by a form of epistemic and structural injustice—the dismissal of the knowledge of their own lives and needs that socially marginalized groups experience.”

From a paper by Sergio Julio Chión-Chacón and Kevin Antonio Álvarez García:

“This study empirically investigates the impact of Inflation Targeting (IT) on nominal interest rates over the past 40 years, focusing on 10 advanced and emerging economies. By using a Binary Regime Model embedded within a Backward-Looking Taylor, our findings confirm that IT adoption has significantly contributed to reducing interest rates, with the strongest effects observed in Latin American countries. To reinforce these results, we incorporate Smooth Transition Regression (STR) models, with and without instrumental variables, allowing for a more suitable representation of gradual policy transitions. The STR estimates consistently support our main findings, validating the robustness of the observed impacts. Furthermore, we show that, both before and after IT implementation, central banks display a stronger emphasis on responding to inflation than to the output gap, with this focus intensifying under IT regimes.”

From a paper by Emiliano Brancaccio, Fabiana De Cristofaro, and Raffaele Giammetti:

“The so-called ‘IMF-OECD consensus’ suggests that labour market deregulations increase employment and reduce unemployment. This paper presents a meta-analysis of research on this topic based on MAER-NET guidelines. We examine the relation between Employment Protection Legislation indexes on one hand, and employment and unemployment on the other. Among 53 academic papers published between 1990 and 2019, only 28 per cent support the consensus view, while the remaining 72 per cent report results that are ambiguous (21 per cent) or contrary to the consensus (51 per cent). The decline in support for the consensus view is particularly evident in the last decade. Our results are independent of the citations of papers examined, the impact factor of journals and the techniques used. A FAT-PET meta-regression model confirms these outcomes.”

From a paper by Marek A. Dąbrowski, Jakub Janus, and Krystian Mucha:

“In this paper, we propose a novel approach to classifying inflation-targeting (IT) economies based on fractionally integrated processes. Motivated by the rising prevalence and diversity of IT strategies, we leverage variation in the persistence of inflation rate series to identify four de facto IT strategies, or ‘shades’ of IT. Moving from negative orders of fractional integration, indicating anti-persistent behaviour, to more persistent long-memory processes, often associated with less credible policy frameworks, we classify countries into average IT, strict IT, flexible IT, and uncommitted IT categories. This framework sheds light on the differences between declarative and actual monetary policy strategies across 36 advanced and emerging market economies. Notably, we demonstrate that while most economies fall into the flexible IT category, extreme cases, including the uncommitted IT category, occur with marked frequency. Furthermore, we link our IT classification to institutional features of national monetary frameworks using ordinal probit models. The results suggest that differences across IT categories are related to variations in the maturity and stability of IT frameworks, with less pronounced connections to central bank independence and transparency.”

From a paper by Martin Boďa and Mariana Považanová:

“In order to canvass the state of the art of research on Okun’s law, the paper surveys 84 articles published in Web of Science™ journals between 1995 and 2020 occupied with estimating the relationship between unemployment and output in the spirit of an approach proposed by Okun (1962). A bibliometric analysis is conducted to identify the most influential works and authors, to establish links between them, and to outline research fronts with main paths of knowledge diffusion. Under a content analysis, the articles included in the survey are further classified by their leitmotif and research agenda as well as by their geographical scope. The basal methodological choices of the articles are overviewed and their temporal patterns are studied. An emphasis is put on the stylized facts constituting the research agenda of 57 of the surveyed applications of Okun’s law (such as instability over time, asymmetries, or age and gender specificity). A majority of studies estimated Okun’s law on the basis of a regression equation that may suggest that it is unemployment that responds to fluctuations in output and adopted the difference version of Okun’s law. In estimating the gap version, the Hodrick-Prescott filter has continued to be a preferred choice despite its well-known flawed statistical properties. Lotka’s law indicates an above-average level of research productivity of authors in this field. The findings provide insights into the intellectual structure of the empirics of Okun’s law and act as guidance for future research on cyclical unemployment-output fluctuations.”
