These impacts are larger for cities with acidic water and older pipeline systems that allow higher lead levels to leach into drinking water. Further, we show that the impacts are almost exclusively concentrated on the lead status of the birth-city and not the city of residence later in life. An instrumental variable strategy suggests reductions in longevity associated with birth-city lead status of about 9.6 months.

Using pre-industrial rural Estonia as an example, the article studies fertility response to short-term economic stress in a manorial society in eastern Europe. It considers whether the fertility response to rye price fluctuations was deliberate and whether it was socially differentiated. It appears that an increase in the price of rye resulted in the drop of conceptions within the next year and the magnitude of the impact on fertility was roughly similar to that in several other European settings in the 19th century. As long as the manorial system was maintained, farmers were more sensitive to price hikes than the landless, but with the decline of the mutual economic dependence between manors and farms, the landless laborers became more vulnerable to price increases. Our analysis of the timing of the fertility response reveals no deliberate postponement of conceptions immediately before or after the low harvests or price increases. Instead, conceptions dropped only in the spring and summer season of the next year, indicating a non-deliberate and spontaneous response.</div></div>","PeriodicalId":47413,"journal":{"name":"Explorations in Economic History","volume":"96 ","pages":"Article 101653"},"PeriodicalIF":2.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"历史学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We study family reconstitutions of the region linked to information about socioeconomic status, detailed reports of the flood damage, and information on crop prices for the entire study period. We innovate on the literature through our reconstruction of property damage at the parish level, as well as of the economic development in the region, combined with family reconstitutions. We investigate the short-term impact of the flood on marital fertility and child mortality, as well as the long-term impact on age at first childbirth and age at first marriage of individuals who experienced the flood early in life. We use Cox proportional hazard models to study mortality. The timing and the likelihood of transitions are investigated with the help of mixed parametric cure models. We find that child mortality, but not infant mortality, increased in the flood aftermath, but that this increase in mortality was not attributable to the flood-related damage. Furthermore, we find no evidence of changes in the timing of first childbirth or marriage among the affected individuals.

The importance of obtaining high-quality training data for the performance of the record linkage algorithm largely, however, remains unknown. This paper comprehensively examines the role of training data, and—by extension—improves our understanding of best practices in supervised methods of probabilistic record linkage. First, we compare the speed and costs of building training data using different methods. Second, we document high rates of conditional accuracy across the training data sets, rates that are especially high when built with access to more information. Third, we show that data constructed by record linking algorithms learning from different training-data-generation methods do not substantially differ in their accuracy, either overall or across demographic groups, though algorithms tend to perform best when their feature space aligns with the features used to build the training data. Lastly, we introduce errors in the training data and find that the examined record linking algorithms are remarkably capable of making accurate links even working with flawed training data.</div></div>","PeriodicalId":47413,"journal":{"name":"Explorations in Economic History","volume":"96 ","pages":"Article 101656"},"PeriodicalIF":2.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143553003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"历史学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This decline was driven primarily by stagnation among the top 1 % of earners and significant wage growth at the lower end of the income distribution. However, the relative underperformance of the top earners was largely influenced by a major compositional shift triggered by unprecedented increases in corporate and personal income tax rates. These tax changes led to a shift in business preferences toward partnerships, resulting in a substantial transition from salaried employment to self-employment. This shift, previously overlooked in inequality studies, resulted in a 30 % overestimation of wage compression, significantly altering the wage distribution dynamics of the 1940s.</div></div>","PeriodicalId":47413,"journal":{"name":"Explorations in Economic History","volume":"96 ","pages":"Article 101651"},"PeriodicalIF":2.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"历史学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use individual-level longitudinal data from 1813 to 1967 for a rural/semi-urban area in southern Sweden with similar economic development, occupational structure, life expectancy and fertility to the country as a whole. We found that during the first part of the 19th century, when agriculture was reformed and grain became an export product, workers, but not farmers and other social groups, deliberately postponed births in response to rising food prices. Despite these efforts to maintain consumption, workers and their families suffered increased mortality risks during years of high food prices, indicating that they lived close to the subsistence margin and could not save to ensure consumption in bad times. In the second half of the 19th century, rising real wages improved workers’ living conditions and the mortality response to economic stress decreased. By the 20th century, as the economy progressed and welfare systems emerged, the mortality response disappeared entirely.

Both areas faced the challenge of population pressure due to high fertility and falling mortality. Between them was a textile town, Verviers, which was one of the cradles of industrial revolution in continental Europe. Young people in rural areas engaged in circular migrations with the goal of marrying and establishing new households, which became increasingly difficult in communities with growing populations and diminishing opportunities. Moving from farm to farm also increased as the ownership of farmland became more concentrated and unequal. Those who did not succeed in the countryside moved to Verviers and rarely returned to their rural roots. Instead, they entered a different migratory system within the urban-industrial agglomeration. When urban economic conditions were bad, migrants from Ardennes and the Pays de Herve did not leave Verviers for other industrial areas. They preferred to remain close to kin living in the villages.
