This paper studies the impact of COVID-19 outbreak on health inequality from the perspective of risky behaviors. We adopt the novel synthetic difference-in-differences approach based on longitudinal data in China. The uniqueness of China’s COVID-19 outbreak in 2020 helps disentangle the demand-side reasons from supply-side restrictions. Results show that people with more advantaged backgrounds reduced cigarette and alcohol consumption following the pandemic, while the disadvantaged were little affected. The disparities in risky behaviors are unlikely driven by unequal income reduction and we find null pandemic effect on mental health. However, there is suggestive evidence of heterogeneous responses in social activities and health attention. While social activities may eventually return to the pre-pandemic level, enlarged gap in attention to personal health likely persists, leading to widened health inequality.</div></div>","PeriodicalId":48183,"journal":{"name":"Journal of Comparative Economics","volume":"53 3","pages":"Pages 856-881"},"PeriodicalIF":3.1,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144852333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To answer this, we run a large-scale experiment in China to estimate the cost-effectiveness of influenza and pneumococcal vaccines on elderly patients with chronic obstructive pulmonary diseases (COPD). Vaccinated patients – relative to the control group – experienced improvements in their COPD condition, which led to a substantial decrease in their medical expenditure (public medical insurance reimbursements and out-of-pocket expenses). Our conservative difference-in-differences estimates imply that every dollar spent making vaccination freely available reduced public medical insurance reimbursements by at least 10 to 33 dollars, and reduced total medical expenditure by 15 to 46 dollars. Comparing across beneficiaries, we find that patients aged 70 and above, those with more severe COPD symptoms, and those residing in rural areas, benefitted the most from immunization. Our results shed light on the long-run viability of public immunization programs, and for whom should immunization be prioritized.</div></div>","PeriodicalId":48183,"journal":{"name":"Journal of Comparative Economics","volume":"53 3","pages":"Pages 816-833"},"PeriodicalIF":3.1,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144852331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, instead of the state funding justice, justice funds the state. The cost to the King was a loss of control over the judiciary and biased legal decisions. We develop a model of judicial venality and build on this model to provide an analytical narrative of the rise and decline of judicial venality in Old Regime France. Historically, judicial venality enhanced legal capacity whereas the French kings faced with limited opportunities to raise taxes and to borrow. Lack of control over the judiciary, however, led to overly costly and time-consuming trials, resulting in its final demise during the 1789 Revolution.</div></div>","PeriodicalId":48183,"journal":{"name":"Journal of Comparative Economics","volume":"53 3","pages":"Pages 704-726"},"PeriodicalIF":3.1,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144852326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I find that the provision of bonuses leads to much lower quality than in a control group where bonuses are not given. However, offering a bonus while also making work visible to peers motivates the judges to increase both quantity and quality.

For men, this reduction primarily stems from a decrease in consumption quantity, while for women, both a reduction in quantity and a shift toward more environmentally friendly consumption play a role. The effect is more pronounced among individuals with higher educational attainment, indicating that socioeconomic factors influence the environmental impact of retirement.

This finding is extremely robust to a variety of robustness tests, including instrumental variable, propensity score matching, alternative balancing methods that combine weighting and regression, potential omitted variables, restricted samples, alternative measures of credit constraints, different specifications such as Linear Probability, Logit, and Probit models, and clustering standard errors at the country level. Heterogeneity analysis reveals that the detrimental impact of past informality lessens with firm size, firm age, and better structural factors like regulatory quality, trade openness, entrepreneurial dynamism, and public spending.

The WTO accession enhanced international trade between China and the rest of the world by reducing trade barriers. The booming of the export-oriented manufacturing located in coastal and urban areas led to unprecedented rural-to-urban migration in human history. We find that migration leads to large income benefit. We also find that sons from wealthy and better-educated families in rural areas are more likely to grab the job opportunities brought about by the WTO accession and are more likely to migrate, compared with sons from less-wealthy and less-educated families.

Exposure to increased birthplace diversity leads to more households providing financial assistance to friends and strangers, but not to relatives. The favorable impacts stem primarily from within-group diversity and fractionalization, rather than from between-group diversity and polarization. Economic interdependence and broader inclusiveness, as opposed to social trust or outgroup threat, likely drive these effects.
