The in-hospital mortality rates of slaves and freemen: evidence from Touro infirmary, New Orleans, Louisiana, 1855 - 1860
Pritchett, Jonathan; Yun, Myeong-Su - 2008
Using a rich sample of admission records from New Orleans Touro Infirmary, we examine the in-hospital mortality risk of free and enslaved patients. Despite a higher mortality rate in the general population, slaves were significantly less likely to die in the hospital than the whites. We analyze...

The evolution of the racial gap in education and the legacy of slavery
Bertocchi, Graziella; Dimico, Arcangelo - 2011
determined by the initial gap. We obtain these results with 2SLS estimates where slavery is used as an instrument for the initial … gap. The excludability of slavery is preliminarily established by instrumenting it with the share of disembarked slaves … initial racial gap in education and that slavery affects growth indirectly through this channel. …

The aggregate Le Chatelier Samuelson principle with Cournot competition
Koebel, Bertrand M.; Laisney, François - 2010
This paper studies the aggregate substitution and expansion effects triggered by changes in input prices, in a context where firms supply a homogenous commodity and compete in quantities à la Cournot. We derive a sufficient condition for the existence of a Cournot equilibrium and show that this...

Interaction and non-neutral effects of factors in Chinese wheat production
Selim, Sheikh; Parvin, Naima; Patel, Vasita - 2010
In this paper we examine the role of the interaction between labour productivity and the use of factors in explaining the recent (1998-2007) 11% decline in wheat production in China. We employ a non-neutral stochastic production frontier approach that enables us to identify the interaction and...

The Elasticities of Complementarity and Substitution
Broer, Peter - 2004
This paper argues that the conventional definition of the elasticity of complementarity is not well suited to deal with the case of increasing returns. It proposes a slightly different formula, that uses a distance function formulation instead of a production function. The proposed definition...

Using firm optimization to evaluate and estimate returns to scale
Gorodnichenko, Yuriy - 2008
At the firm level, revenue and costs are well measured but prices and quantities are not. This paper shows that because of these data limitations estimates of returns to scale at the firm level are for the revenue function, not production function. Given this observation, the paper argues that,...

Returns-to-scale properties in DEA models: The fundmantal role of interior points
Krivonozhko, Vladimir; Førsund, Finn R. - 2009
Attempts can be found in the DEA literature to identify returns to scale at efficient interior points of the production possibility set on the basis of returns to scale at points of the corresponding reference sets. However, an opposite approach is put forward in this paper, advocating that...

Slave prices, geography and insolation in 19th century African-American stature
Carson, Scott Alan - 2007
The use of height data to measure living standards is now a well-established method in the economic literature. Moreover, while much is known about 19th century black legal and material conditions, less is known about how 19th century institutional arrangements were related to black stature....
