This paper explores the contemporaneous effects of Confederate monuments dedicated in the Post-Reconstruction South. I combine monument, election, and census data to create an election-year panel dataset of former Confederate counties between 1878–1912, then exploit the temporally staggered and geographically distributed dedication of monuments using a generalized difference-in-differences design. I find that monuments caused increases in Democratic Party vote share and decreases in voter turnout, with less robust decreases in Black population share. I find some evidence that more intense monument-building is associated with a decrease in Black lynchings. I also find varying effects based on the era of monument dedication, the intensity of monument-building, and monument characteristics. To address potential mechanisms, I present evidence that monuments were associated with increased use of famous Confederate names for children and show that decreases in voter turnout occurred exclusively in areas with larger Black population shares. Overall, my results suggest monuments promoted a distorted view of Civil War history that primarily persuaded southern whites, but also contributed to Black political suppression. The findings have implications for current debates over Confederate monuments in the United States.

While piece rates were a common form of payment in manufacturing, historians have rarely tried to understand the cross-sectional structure of piece-rate prices. This paper examines piece rates paid to weavers at a US cotton factory and demonstrates that in most cases expected daily earnings were constant across different piece rates. While some rates did result in higher daily earnings, there is no evidence of gender discrimination in the assignment of such rates.

This paper delves into infrastructure projects initiated during the dictatorship in Spain, particularly the construction of reservoirs and dams. These projects were instrumental in bolstering support for right-wing factions advocating for Franco’s regime over the years. However, our research reveals a notable trend: areas where dams were erected by the regime demonstrate diminished political backing for right-wing parties in the post-dictatorship era. We present evidence suggesting that this phenomenon is driven by the use of forced labor in dam construction by the regime, as inferred from the proximity to concentration camps. To address endogeneity concerns, we instrument dam construction with river gradient suitability.

The study revisits trends and drivers of wealth inequality and accumulation since the onset of industrialization. Empirical analysis reveals that Western countries are both wealthier and more equal today than a century ago. Wealth concentration has declined in all countries over the past century, remaining at historically low levels in Europe, while rising in the United States. These trends are largely driven by new wealth accumulation among the lower and middle classes, primarily through housing and pension savings, rather than a decline in the fortunes of the affluent. The findings challenge the view that unregulated capitalism inevitably leads to extreme wealth concentration and question the idea that wealth equalization requires shocks to capital, such as wars or progressive taxation. Instead, the evidence emphasizes the equitable effects of economic and political institutions that enable ordinary individuals to build personal wealth.

The average white male born in 1900 earned 2.6 times more labor income over their lifetime than the average Black male. This gap is nearly twice as large as the more commonly studied cross-sectional Black–white earnings gap because 48% of Black males born in 1900 died before the age of 30 as compared to just 26% of white males. We calibrate a model of optimal consumption in a world with mortality risk to data describing the life-cycle earnings and survival probabilities of Black and white males born between 1900 and 1970. We find that convergence in Black and white mortality rates led to a 50% reduction in Black–white welfare gaps between the 1900 and 1920 birth cohorts, even as cross-sectional Black–white income gaps for those cohorts remained relatively constant. However, the Black–white welfare gap stagnated for the 1920 to 1970 birth cohorts as gaps in Black–white life expectancy and income remained stable and large.

The Malthusian trap is a well recognized source of stagnation in per capita income prior to industrialization. However, previous studies have found mixed evidence about its exact strength. This article contributes to this ongoing debate by estimating the speed of convergence for a panel of 9 preindustrial European economies over a long period of time (14th–18th century). The analysis relies on a calibrated Malthusian model for England and -convergence regressions. I find evidence of significant differences in the strength of the Malthusian trap between preindustrial European economies. The strongest estimated Malthusian trap is in Sweden, with a half-life of 20 years. The weakest estimated Malthusian trap is in England, with a half-life of about 230 years. This implies that some preindustrial economies were able to experience prolonged variations in their standards of living after a shock, while still being subject to Malthusian stagnation in the long run.

What explains the emergence of centralized fiscal institutions and information-intensive monetary taxation? This is the first study to estimate the effect of state capacity expansion on labor coercion as taxation, a practice known as corvée labor. To do so, I construct a new database covering eighteen Indonesian residencies over thirty-two years (1874–1905) during the period of Dutch colonial rule. I document the wide use of corvée labor and find that national-level policy centralized state finances by gradually replacing corvée with a head tax. At the same time, a residency-level panel data analysis shows that local state capacity expansion, primarily indigenous officials working as agents for the state, slowed the movement away from corvée. These estimates are supported by an IV strategy that uses effective distance to the capital as an instrument for local state capacity. The relationship between state capacity expansion and fiscal modernization therefore depends on what part of the state is expanding and whether interests across types of taxation differ within the state bureaucracy. Opposing interests of different state actors can be key in understanding fiscal modernization and public labor coercion.

The article presents a novel method that enables the formation of historical patent families. Patent families are useful for studying the value of inventions and identifying key technologies, as they indicate geographic diffusion and higher patenting costs. The concept of patent family has not been employed in historical contexts as historical sources generally lack information about priority rights. The article provides a definition of a historical patent family, where patent families incorporate patents with the same invention core. The method is applied and evaluated by constructing Swedish patent families in 1885–1914 with historical patent data from Finland and the United States. Moreover, the article introduces the Patent Diffusion Index (PDI), which is an indicator of historical patent families which can be used to study the sequence and pace of market entry. The article exemplifies how historical patent families open novel perspectives on patent value and technology diffusion in contrast to current indicators, such as patent fees, which usually are bound to national contexts. The method is applicable to any national patent data, and patent drawings are suggested as an effective way to form historical patent families.

This paper explores the prevalence of in-kind wages in medieval labour markets and the underlying reasons for their use. Using a new dataset of agricultural labourers in medieval England, we demonstrate that, until the late fourteenth century, wages were recorded anonymously and most remuneration was done through in-kind payment. From the 1370s, however, labour remuneration shifted increasingly to cash and workers began to be named individually in the accounts which recorded their wages. We argue that these changes reveal a fundamental shift in labour relations in late medieval England, providing new empirical insights into the ‘golden age of labour’ that followed the Black Death.

The issue of how elites as a social group form, maintain their position, and influence the society they control is central to the debate on inequality. This paper studies one of the most extremely unequal societies ever recorded — the sugar-based economies in the West Indies — by focusing on the island of St. Croix in the Danish West Indies and examines the emergence and persistence of its economic elite. The study relies on a novel dataset that covers the entire population of the island over 154 years, allowing for a long-run analysis of elite persistence and the effects of significant economic, institutional, and social changes. Our study shows that elite persistence remained high in global comparison throughout the period of interest, despite several 'critical junctures'. These junctures only had a temporary effect. We contend that this result can be attributed to three mechanisms of persistence: inheritance, institutional co-optation and limited franchise. Finally, we find that although the Crucian elite maintained its relative standing, it came at the cost of severe impoverishment in absolute terms.
