We demonstrate that the tendency to treat the natural rate as near-constant would explain the surprisingly low slope of the Phillips curve. We observe that evidence is weak about this basic point—the evidence neither comes close to rejecting the conventional view nor does it reject a very different view in which fluctuations in the natural rate are associated with a substantial fraction of cyclical volatility. We show that the natural rate may have closely tracked the actual rate during the long recovery that began in 2009 and ended in 2019. We explain how the common finding of research in the Phillips-curve framework of low — often extremely low — response of inflation to unemployment could be the result of fairly close tracking of the natural rate and the actual rate in recoveries. Our interpretation of the data contrasts to that of many Phillips-curve studies, that conclude that inflation has little relation to unemployment.</div></div>","PeriodicalId":46094,"journal":{"name":"Research in Economics","volume":"79 4","pages":"Article 101092"},"PeriodicalIF":1.3,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145094591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study argues for a Cap-and-Levy scheme as a more comprehensive and efficient alternative. By directly addressing supply, consumption, and state tax revenues, a Cap-and-Levy approach offers a broader impact on smoking prevalence including existing smokers, while potentially mitigating the unintended consequences of a sales ban, such as fuelling the illicit trade and reducing tax revenues. This analysis suggests that a Cap-and-Levy mechanism warrants consideration as a policy instrument that could outperform the GSB in achieving significant and immediate reductions in smoking-related harm, without the unintended consequences that the GSB would produce.</div></div>","PeriodicalId":46094,"journal":{"name":"Research in Economics","volume":"79 4","pages":"Article 101084"},"PeriodicalIF":1.3,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145048382","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the growth literature lacks the comprehensive empirical evidence on the convergence of institutional quality and its implications for growth convergence particularly in terms of countries’ heterogeneities. This study aims to empirically investigate three types of convergence hypotheses both in economic growth and institutional quality. Moreover, it is examined whether the convergence of institutional quality leads to growth convergence? The empirical analysis is based on sample of 120 countries for 1984–2015 period. The findings reveal striking evidence of disparities in speed of growth and institutional quality convergence. The speed of growth convergence is highest in East Asian, transition, and advanced economies; however, the speed of institutional quality convergence is lowest in these countries. Developing countries show the reverse pattern with highest institutional convergence and lowest growth convergence. Such decoupling empirical dynamics between growth and institutional quality convergence indicate the path dependence and lock-in patterns of developing countries. This study empirically shows that higher speed of institutional convergence alone is unable to foster the growth catch-up process.</div></div>","PeriodicalId":46094,"journal":{"name":"Research in Economics","volume":"79 3","pages":"Article 101079"},"PeriodicalIF":1.2,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144687230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model presents the possibility of ‘Dutch disease’ in the informal sector. Distinguishing between goods and services in terms of marketing and transport costs, the model reveals how resources—especially skilled labour—are allocated between service and manufacturing sectors. Furthermore, it outlines two scenarios for the informal sector, independent and integrated with manufacturing, in exploring how these configurations affect trade and production.
