Social Assistance Programs And Outcomes: Food Assistance In The Context Of Welfare Reform, Sonya Kostova Huffman, Helen H. Jensen Sep 2006

Social Assistance Programs And Outcomes: Food Assistance In The Context Of Welfare Reform, Sonya Kostova Huffman, Helen H. Jensen

CARD Working Papers

Food assistance programs play an important role in meeting the basic needs of low-income households. We consider the complex interactions among food stamps, labor force participation, and food insecurity status of low-income households under different program designs and economic conditions. The analysis uses data from the Survey of Program Dynamics to jointly estimate the role of participation in the Food Stamp Program (FSP), labor market participation and well-being, measured as food security, through the use of a simultaneous equation model. The results of our research suggest that food insecurity has a positive effect on FSP participation while labor force participation ...


Economies Of Feedlot Scale, Biosecurity, Investment, And Endemic Livestock Disease, David A. Hennessy Sep 2006

Economies Of Feedlot Scale, Biosecurity, Investment, And Endemic Livestock Disease, David A. Hennessy

CARD Working Papers

Infectious livestock disease creates externalities for proximate animal production enterprises. The distribution of production scale within a region should influence and be influenced by these disease externalities. Taking the distribution of the unit costs of stocking an animal as primitive, we show that an increase in the variance of these unit costs reduces consumer surplus. The effect on producer surplus, total surplus, and animal concentration across feedlots depends on the demand elasticity. A subsidy to smaller herds can reduce social welfare and immiserize the farm sector by increasing the extent of disease. While Nash behavior involves excessive stocking, disease effects ...


Optimal Design Of Permit Markets With An Ex Ante Pollution Target, Sergey S. Rabotyagov, Hongli Feng, Catherine L. Kling Aug 2006

Optimal Design Of Permit Markets With An Ex Ante Pollution Target, Sergey S. Rabotyagov, Hongli Feng, Catherine L. Kling

CARD Working Papers

In this paper, we examine the design of permit trading programs when the objective is to minimize the cost of achieving an ex ante pollution target, that is, one that is defined in expectation rather than an ex post deterministic value. We consider two potential sources of uncertainty, the presence of either of which can make our model appropriate: incomplete information on abatement costs and uncertain delivery coefficients. In such a setting, we find three distinct features that depart from the well-established results on permit trading: (1) the regulator’s information on firms’ abatement costs can matter; (2) the optimal ...
