PROOF OF PROPOSITION 1 (CONSTANT PARAMETERS) To derive optimal budget and allocation, we solve the HJB equation (6) (A-1) Differentiating the right hand side of (A-1) with respect to R i , we get the first-order conditions (FOCs) for each region i: 1 1 () 0 2 i i i V R       , (A-2) which upon rearrangement yields the implicit optimal ad expenditures(More)
DDE and the o,p' and p,p' isomers of DDT were assayed in 94 human biopsy fat samples from hospitals in Delhi by gas chromatography. DDT was present in all except 2 samples at concentrations from 0.17 to 176.5 mg per kg of body fat. The average total DDT content was 21.8+/-2.9 mg/kg, of which 45.9% was DDE. The average value reported in a similar study in(More)
