Despite anecdotal examples and widespread media coverage, there is limited empirical evidence on the broader role of package size reductions in inflation measurement. This paper quantifies how changes in package size among packaged food products influence measured inflation and investigates the mechanisms behind these size changes. Using U.S. retail scanner data from 2012 to 2019, we document that the average package size (measured in grams per UPC) declined by 14.6% over the period. We show that these size reductions are not the result of downsizing in the conventional sense-i.e., shrinking of the same product-but are instead driven almost entirely by product turnover: newly introduced products tend to be smaller than the products they replace. To isolate the impact of package size on food inflation, we compute two hedonic price indices: one that adjusts for size and other attributes and a counterpart that omits size. We find that when size is omitted from the hedonic model, annual inflation is understated each year. As a result, over the entire period, accumulated inflation would be 3.7 percentage points lower if size changes were not accounted for. Finally, we explore heterogeneity in size reductions. We find they are more pronounced among products purchased by high-income households, in states without unit pricing regulations, in sugary products, and in non-bulky goods. This suggests that product shrinkage may result from consumer inattention and market segmentation strategies. We benchmark our findings against official inflation statistics and methodological practices to highlight key similarities and differences.</div></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":"105 ","pages":"Article 103261"},"PeriodicalIF":1.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146079220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite numerous studies investigating the relationship between cartel activity and productivity, there has been no systematic analysis of how cartel recidivism affects productivity growth within an industry. This paper aims to fill this gap by quantifying the relationship between cartel recidivism and productivity growth. For this reason, we have used data drawn from US manufacturing cartel cases over the period 1966-2016. In particular, we focus on firms that repeatedly engage in cartel activity (“true recidivists”) and their impact on industry-level productivity growth.. Our empirical analysis employs classical econometric techniques (OLS) alongside quantile regression methods. Our primary finding indicates a robust negative relationship between recidivism and productivity growth in nearly all empirical specifications. By contrast, in non-colluding markets, the absence of multiple and single offenders is positively associated with productivity growth. Finally, we find that higher recidivism rates are associated with patterns consistent with lower observed effectiveness of anti-cartel enforcement. These findings suggest an important link between cartel recidivism, competition policy effectiveness, and productivity growth.</div></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":"105 ","pages":"Article 103267"},"PeriodicalIF":1.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the legal profession, specifically how a district-specific bar exam impacts occupational licensing and labor mobility across districts. Licensing regulation brings unintended consequences: extreme heterogeneity across districts in licensing exam difficulty, unfair admission procedures, and inefficient mobility of exam candidates and workers. We leverage a policy change in the grading procedure of the exam, transitioning from grading within the local district to grading in a randomly assigned different district, and find that exam fairness is substantially restored following this reform. A theoretical model of occupational licensing, labor mobility, and strategic interaction among licensing boards supports our findings. This study provides the first evidence of regulatory competition driven by such interactions. Understanding how to regulate these uneven standards in bar exams can help inform the regulation of other professions where fairness and efficiency in professional licensure are critical issues.</div></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":"105 ","pages":"Article 103270"},"PeriodicalIF":1.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146173131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate this policy’s impact, we estimate a two–stage empirical model. In the first stage, we estimate a structural model applied to air transport; in the second stage, we estimate the link between passenger flows and regional tourism flows. In this way, we use exogenous aviation shocks (subsidies to LCCs) to analyze the causal effect on tourist arrivals. This model is estimated using data on aviation and tourist flows from European to Italian regions during 2016–2018. Counterfactual analyses consider different regimes for implementing the policy, i.e., a subsidy adopted by a benevolent central planner and/or by sub–national institutions. Our simulations show that subsidies to LCCs are effective in stimulating tourism and that a centralized regime is more effective than a decentralized one. In fact, the latter generates externalities in regions that do not implement the subsidy, making the decentralized policy economically suboptimal.</div></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":"104 ","pages":"Article 103242"},"PeriodicalIF":1.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145839500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
