Biology, Diseases, and Economics: An Epidemiological History of Slavery in the American South

The economic history of antebellum southern slavery has been and is the subject of ongoing debates among scholars. The literature includes assessments about the efficiency of slavery as well as about the adequacy of slave living standards and diets. Yet this literature under appreciates the important biologic and historical role that parasitic diseases played in the history of slavery. Recognizing the role of parasitic diseases calls into question some prevailing interpretations of slavery. Lacking direct evidence on slave diets, scholars turned to anthropometric evidence as proxies for the living standards of slaves, leading to the prevailing view that adult slaves were given adequate sustenance, but slave infants and children were severely malnourished. We argue it was not slave diets, but the combination of the plantation system and diseases that caused abnormally small slave children. The diseases that concern us, primarily hookworm and malaria, affected slaves ('blacks') and free labor ('whites') differently. Many slaves were concentrated on large plantations with infants and younger children crowded into 'nurseries.' This system allowed the maintenance and spread of diseases that adversely affected younger slaves. Southern white children however were less likely to be raised in conditions so conductive to parasitic diseases. The disease ecology of the antebellum South has implications for the prevailing view that slavery was more efficient than free labor. Biologic evidence indicates that people of tropical West African ancestry are more resilient to the effects of hookworm and malaria than European descendents. Thus when whites did contract these diseases, they were more afflicted than blacks. When slaves entered the adult work force they were taken from disease breeding grounds (slave nurseries) and sent into relatively (for blacks) healthy fields, while whites that went into the fields found a disease environment that was typically worse than that of their childhood. If black adults were more productive than were white adults because of a greater resilience to parasitic diseases, then part of any measured difference in productivity between slave and free farms should be attributed to the disease resistance of African descendents, rather than to any inherent efficiencies of slavery.     

A comparative study of slave societies

This essay focuses both on theoretical issues and empirical evidence concerning the inevitability of slavery as an economic stage over the course of development. Different types of slavery are described and a number of common hypotheses about the determinants of slave societies and/or slavery are discussed. Several new hypotheses are also proposed which focus upon family and social-structural variables and also upon political factors. The major hypotheses are tested, using a worldwide sample of 60 primitive and peasant societies arranged according to level of economic development. The various older theories are found to explain poorly the presence of slavery while the data give some support to the newly proposed causal relationships.     

Modern slavery,corruption, and hysteresis

We develop a model where firms profit from coercing workers into employment under conditions violating national law and international conventions and where corrupt public servants prosecuting violations of the rules are willing to turn cases down if bribed. Firms and public servants are heterogeneous. Firms benefit differently from the use of coerced labour whereas public servants have differing intrinsic motivations to behave honestly. Moreover, there is a socially determined warm-glow effect: honest public servants feel better if their colleagues are honest too. The determination of bribes is modelled via Nash bargaining between the firm and the corrupt civil servant. It is shown that multiple equilibria and hysteresis are possible. Depending on history, an economy may be trapped in a locally stable high-corruption, high-slavery equilibrium and major changes in government policies may be necessary to move the economy out of this equilibrium. Moreover, we show that trade bans that are effective in reducing slavery in the export industry tend to raise slavery in the remainder of the economy. It is possible that this leakage effect dominates the reduction of slavery in the export sector.     

The legacy of slavery on hate crime in the United States

Does slavery play a role in explaining why some areas are more prone to hate crimes? Using county-level data on slavery in 1860, I find evidence that U.S. counties with a higher share of slaves in the population more than 150 years ago are more likely to observe hate crime incidents today. One percentage point increase in the share of slaves in the population in 1860 is associated with 0.018 more hate crime incidents per 100,000 population directed at blacks today. Additionally, there is evidence that slavery is associated with more hate crime incidents directed towards Jews and LGBT population. This result supports previous studies which find persistence in cultural norms and racial attitudes.     

Recombinant Slave Equilibria and Their Cure: Living Wage Full Employment

Scapegoating and slavery are effects of ordinary necessitous interpersonal relations that are naturally selected, extant in all familial and societal hierarchal equilibria, and evolved from primordial parasitism through our primate cousins in order to manage uncertainty. As such, slavery predates and survives all legal strictures. Although social equilibria have progressed equitably in the developed world, it is suggested that slavery's modern cure will only be found by precluding the genetic proclivity to exclude with an actual living-wage, full-employment economy.     

Equilibria under deferred acceptance: Dropping strategies,filled positions,and welfare

We study many-to-one matching markets where hospitals have responsive preferences over students. We study the game induced by the student-optimal stable matching mechanism. We assume that students play their weakly dominant strategy of truth-telling.Roth and Sotomayor (1990) showed that equilibrium outcomes can be unstable. We prove that any stable matching is obtained in some equilibrium. We also show that the exhaustive class of dropping strategies does not necessarily generate the full set of equilibrium outcomes. Finally, we find that the ‘rural hospital theorem’ cannot be extended to the set of equilibrium outcomes and that welfare levels are in general unrelated to the set of stable matchings. Two important consequences are that, contrary to one-to-one matching markets, (a) filled positions depend on the equilibrium that is reached and (b) welfare levels are not bounded by the optimal stable matchings (with respect to the true preferences).     

Race,Gender, and Familial Status: Discrimination in One US Mortgage Lending Market

This paper, using data from the 1992 Boston Federal Reserve study of mortgage lending, reports preliminary evidence of patterns of gender and familial status discrimination that differ markedly by race in the US. White couples with children experienced familial status discrimination if the female partner was in the labor market, but not if she was at home raising her children. However, African-American or Hispanic couples with children suffered familial status discrimination if she stayed home to raise her children, but much less so, if at all, if she was in the labor market. This pattern of racial differentiation may reflect social norms dating back to slavery that have favored labor force participation for African-American and Hispanic mothers but not white mothers. On the other hand, it was true across racial groups that single women, more than single men, were disadvantaged in the mortgage market by children.     

Induced Preferences, Nonadditive Beliefs, and Multiple Priors

We study a decision maker who follows the Savage axioms. We show that if he or she is able to take unobservable actions that influence the probabilities of outcomes, then it can appear to an outsider as if his or her subjective probabilities are nonadditive. Implications for multiperiod decision are explored. We extend the model to include a second individual who is also able to take a hidden action. We show that this may induce uncertainty-averse preferences over some class of acts, even if the second individual acts to help the decision maker with high probability.     

The Impact of Power Equality,Income, and the Environment on Human Health: Some Inter‐Country Comparisons

Economic studies on environmental degradation generally have a narrow focus on per capita income as an explanatory variable, and often fail to distinguish among the various types of environmental quality or damage. This paper addresses both problems by examining the effect of relative equality in the distribution of power on environmental outcomes, and making a clear distinction between health‐related environmental outcomes and so‐called ‘environmental amenities,’ only the latter of which should correlate strongly with income. This paper introduces a national index of power equality that is derived from related socioeconomic variables, and studies its effects on individual country achievement in addressing environmental quality and population health. This model is applied to a data set of 180 countries, as well as to subgroups of the entire country set. Employing disability‐adjusted life expectancy and the population child mortality rate as two health proxies, this paper finds that power equality in most cases positively influences population health, and that power equality is in every case no worse and in some cases better than per capita income at explaining population health.     

Pure numbers effects, market power, and tacit collusion in posted offer markets

This paper studies the effects of seller concentration and static market power on tacit collusion in extensively repeated laboratory posted-offer markets. Contrary to the implications of some earlier research, we find that tacit collusion does not become pervasive with extensive repetition. In a ‘strong no-power’ design persistently competitive outcomes are observed in markets with three or four sellers. Even duopolies are frequently competitive in this design. Unilateral market power raises prices, as predicted. However, static Nash predictions fail to organize outcomes across power treatments, because tacit collusion moves inversely with concentration. Excess capacity appears to explain observed tacit collusion levels.     

Does the road to serfdom lead to the Servile State?

Hilaire Belloc's The Servile State is often seen as an antisocialist tract arguing that “socialism is slavery.” It is typically assumed that an appreciation and defense of free market capitalism, as well as a general dislike of government intervention must motivate the its thesis. Nevertheless The Servile State is an argument against what Belloc saw as unbridled capitalism not collectivism. Belloc defines capitalism to mean a state in which there is a skewed distribution of wealth in society where the majority of people are dispossessed, proletariat, and a minority makes up the capitalist, property owning class. For Belloc capitalism is an inherently unstable system and servile measures arise to ameliorate insecurity and instability.     

Noxious Facilities, Environmental Damages, and Efficient Randomized Siting

This paper considers the efficient siting of a noxious facility that causes environmental damages (for example, increased pollution) in the host community. The analysis shows that there can be multiple efficient locations without transfers, and that an efficient location need not have the smallest WTA or WTP. In general, there exist randomized outcomes that are ex ante efficient and that Pareto dominate efficient outcomes. The analysis also shows that a community’s most preferred lottery never provides full insurance. Under some conditions, lotteries with no host compensation are Pareto superior to those with compensation.     

Public financing of health expenditures,insurance, and health outcomes

The effects of public financing of health expenditures, insurance coverage and other factors on health outcomes are examined within health production models estimated using 1960–1992 data across 20 OECD countries. Mortality rates are found to depend on the mix of health care expenditures and the type of health insurance coverage. Increases in the publicly financed share of health expenditures are associated with increases in mortality rates. Increases in inpatient and ambulatory insurance coverage are associated with reduced mortality. The effects of GDP, health expenditures and age structure on mortality are similar to those in previous studies. Tobacco use, alcohol use, fat consumption, female labour force participation, and education levels are also significantly related to overall mortality rates. Increases in income inequality are associated with lower mortality rates, suggesting that the negative relationship between inequality and health outcomes suggested by some previous studies does not remain when a more complete model is estimated. The result that increases in public financing increase mortality rates is robust to a number of changes in specifications and samples. Thus, as countries increase the level of their health expenditures, they may want to avoid increasing the proportion of their expenditures that are publicly financed.     

Turgot: a critic of physiocracy? An analysis of the debates in Éphémérides du Citoyen and in correspondence with Dupont

Abstract

Anne-Robert-Jacques Turgot (1727–1781) is one of the few French economic theorists who led a political career and held ministerial office. He continues to intrigue both historians and historians of economic thought where his relationship with the physiocrats is concerned. Does Turgot fully share their belief system, or does he only borrow a few elements from it? Is he a critical author of this school of thought? To date, no agreement has been reached on this subject. This paper attempts to answer some of these questions in an objective manner, drawing on the evidence provided by texts and therefore minimising the interpretations. The sources we will primarily refer to are the Éphémérides du citoyen and Turgot's correspondence with Dupont. We will revisit the economic themes of large- and small-scale farming, as well as savings, and discuss Turgot's views on slavery and the “sectarian spirit” of the physiocrats.     

Gender,Decent Work,and Global Production Sharing in Indonesian Manufacturing

Abstract:

Global commodity chains reflect and affect gendered labor markets. This article uses the Decent Work framework from the International Labour Organization to analyze employment outcomes for Indonesian workers in manufacturing. This research investigates trends in feminized manufacturing sectors in variously sized firms. Regression analyses is used to evaluate how firm characteristics related to global production sharing effect decent work outcomes for women and men, as well as female share of employment itself. The results suggest that exports and FDI affect men and women differently and that feminization and decent work outcomes depend on how the sector is positioned along the global value chain.     

Schumpeter,Keynes and the theory of economic evolution

The contribution deals with a nonlinear dynamic macro-economic model which is used for simulation runs. Conditions and model specifications allowing for global stability are investigated and tested. Based on this some well-known facts as Schumpeterian long-wave phenomena, Keynesian unemployment, productivity growth effects are simulated. Moreover specifying an instrumental variable for state interventions policy issues are also discussed. With this runs it is shown that minor changes of parameters may provide totally different outcomes and different economic developments.     

The relative efficiency of slave agriculture: a comment

In their book Time on the Cross, Fogel and Engerman (FE) present evidence that average factor productivity was greater for larger Southern slave farms in 1860 than for both free farms and smaller slave farms. In a recent article, Field (1988) lends support to the FE theory by finding that an upward shift in the production function occurs for slave farms at 15 slaves, the size at which FE propose that gang labour became feasible. In a more recent article, Grabowski and Pasurka (GP) contradict both FE and Field by finding that there was no relationship between the size of slave farms and their efficiency. The present paper extends both GP's and Field's work and refines a point made by FE. We distinguish between a technological advantage due to the gang labour system and revenue inefficiency due both to the incentive structure of slavery and the repugnance of gang labour, two factors which foster rational shirking and resistance by slaves. That is, we propose that relative to small slave farms, large slave farms may have enjoyed a higher revenue frontier but that actual output and revenue fell farther below their frontier. Our construction is consistent with the historical view that emphasizes the harshness of slavery, the repugnance of the gang labour system, and the rational resisting behaviour of the slaves. We test this hypothesis with the stochastic frontier function approach as did GP. However, our findings contradict them. We find, consistent with both FE and Field, that large slave farms exhibited superior technology over small farms. More importantly, we find empirical confirmation of our theory that large slave farms suffered greater revenue inefficiency than smaller slave farms.     

Admission standards,student effort,and the creation of skilled jobs

We consider the implications of expanding enrollment through lower standards in a model with human capital externalities and a market failure. Workers and firms make uncoordinated investment choices prior to random matching. Investment choices depend on the expected productivity of the counterpart in production. The setting generates a potential human capital externality as a more skilled labor force induces more skilled job openings. Exploiting the externality is complicated by a market failure which may cause some workers to earn a degree but not put forth the effort required to become highly skilled. We show that beyond a threshold, increased enrollment through low standards can be poor policy. Policies which increase returns to agents and firms in best matches can improve outcomes.     

Sorting,peers, and achievement of Aboriginal students in British Columbia

Abstract We examine the contribution of differences in school environments to the gap in education outcomes between Aboriginal and non‐Aboriginal students. We find both substantial school‐level segregation of Aboriginal and non‐Aboriginal students and a substantial gap in test scores. Conventional achievement gap decompositions attribute roughly half of the grade 7 test score gap to between‐school differences and half to within‐school differences. The segregation of Aboriginal students suggests that peer effects might explain some of these between‐school achievement differences. However, we find that peer effects associated with a greater proportion of Aboriginal peers, if anything, improve value‐added exam outcomes of Aboriginal students.     

Child cash benefits and family expenditures: Evidence from the National Child Benefit

Income may improve child outcomes through two mechanisms: as a direct input into health and education, or indirectly, by reducing household financial stress. We exploit policy‐induced changes in refundable tax benefit income in Canada to study these two potential mechanisms. Our findings suggest that additional income may improve outcomes through both mechanisms: some benefit income is spent on direct education inputs, while some is spent on everyday items likely to improve the general conditions children face. Additionally, some families reduce spending on risky behaviour items. Spending responses to benefit generosity appear to vary by income and by child age.
