In addition, its heterogeneity and mechanism are also analyzed. The results show that (1) city innovation ability is significantly improved by the BC policy, and this is still valid after robustness tests.

Discriminatory tariffs lead to Cournot competition, whereas uniform tariffs lead to diverse competition modes. If exporters are identical in production costs, all the trading countries are better off under the uniform rather than discriminatory tariff regime, which suggests a possibility that countries reach an agreement on the most-favored nation (MFN) as a preferred tariff regime. For asymmetric costs among exporters; however, the competition mode determined endogenously under the uniform tariffs does matter for the welfare comparison. If Cournot competition emerges, then each country's preference is consistent with conventional wisdom. That is, the importing country and high-cost exporters prefer a discriminatory tariff while low-cost exporters have a uniform tariff regime. However, if the uniform regime leads to either Bertrand or asymmetric competition mode, then the cost gap between exporters would be the determinant factor. Only when the cost gap is sufficiently small, the uniform tariff, required by the MFN clause of the World Trade Organization, can be beneficial to all trading countries.</p>","PeriodicalId":46233,"journal":{"name":"Bulletin of Economic Research","volume":"76 1","pages":"95-120"},"PeriodicalIF":0.8,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46953807","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}

Hence, this study attempts to investigate the level of loyalty demonstrated by rural microfinance borrowers toward their respective service providers. To accomplish this, an unbalanced panel data, comprising 1101 unique MFIs and spanning the timeframe 2010–2018, were obtained from the World Bank database and thereafter subjected to conventional econometric techniques and a series of robustness tests, including endogeneity-corrected methods, alternative proxies, and sub-sample analyses.

In recent research, a new debate has arisen as a result of the shift of day-to-day activities to virtual platforms, which has augmented concerns related to smart (data) access and smart (data) protection. This study examines the economic, social, and psychological indicators of welfare gain within the context of the COVID-19 pandemic and examines their impact on smart access and smart protection using the data of Survey of Health, Ageing and Retirement in Europe and real-time Google Trends from June to August 2020. The findings indicate a negative relationship between smart access and economic crisis caused by COVID-19, while households with sufficient resources support smart protection. Psychological effects including nervousness and anxiety are highly related to smart access. Likewise, being helpful in a time of uncertainty, societal contact, and social measures (hygiene and face mask) significantly and positively impact smart protection.

Independently of the method used, our findings offer strong evidence of an inverted U-shaped relationship between housing finance and inequality. The current level of development of housing finance in SSA, which is at its very early stage, is not yet an effective tool for reducing economic inequality; however, beyond a given threshold, housing finance becomes effective in reducing inequality. Indeed, higher values of housing finance depth above a certain threshold of 6.35% reduce inequality, whereas values below 6.35% and very high values have no significant impact. In addition, there is a slightly positive relationship between housing finance and labor productivity growth in SSA. Results also show that the way housing finance impact inequality is highly dependent on their ability to implement effective crisis fight policies. Controlling for countries’ income levels, legal origin, and regional proximity revealed relative benchmarking, typology, and characteristics of SSA housing finance. These findings suggest some policies to stimulate the development of housing finance in SSA. As a bonus, this paper also highlights several other pillars that can be used to support shared prosperity in SSA.</p>","PeriodicalId":46233,"journal":{"name":"Bulletin of Economic Research","volume":"76 1","pages":"5-40"},"PeriodicalIF":0.8,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42788873","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}

The objective of this study is to examine the relationship between the Medicaid expansion implemented in the context of the Affordable Care Act and consumer bankruptcy, overall and by chapter filing.

We constructed a panel dataset from 2008 to 2017 with states’ data using data from various sources on insurance, bankruptcy filings, and characteristics that may affect bankruptcy, such as income and ethnicity. The outcomes were the annual rates of consumer bankruptcies overall and by chapter at the state level. Between 2008 and 2017, the overall unadjusted bankruptcy filing rate fell from 0.36% to 0.24%. We found that the expansion was associated with a decrease in overall consumer bankruptcy varying between 0.035 and 0.039 percentage points and that the intensity of the effect was modulated by the intensity of the treatment.
