Theoretical Appendix for "Estimating the Effects of a Time Limited Earnings Subsidy for Welfare-Leavers"

This is a an appendix specifying the theoretical model outlined in the text.

Additional Figures for "Estimating the Effects of a Time Limited Earnings Subsidy for Welfare-Leavers"

1. Extra-figureA shows the SSP impacts (treatment minus control group means) for IA for all individuals and for 2 subgroups: those with less than a high school education, and those with a high school education or higher.  This is created by treat_byed.sas reading from wide54r data set 2. Extra-figureB shows the simulated SSP impacts from the normal heterogeneity model (column 4 of Table 6) for two "types": people with a random effect equal to the 20th percentile of the heterogeneity distribution (which is N(0, 1.18)); and  people with a random effect equal to the 80thpercentile of the heterogeneity distribution.   See sim8020.sas   3.  Extra-figureC shows the actual hazard rate into SSP eligibility, and the predicted rate from the the normal heterogeneity model (column 4 of Table 6). See extra-figc.xls

Supplementary Material to "Robust Mechanism Design"

In this appendix to ?Robust Mechanism Design? we provide a set of sufficient conditions which encompass the quasilinear environment. With these conditions, we can generalize the equivalence results presented in Proposition 4 for common prior full support payoff type spaces. The first condition replaces the compactness condition, the second and third conditions generalize the important features of the quasilinear utility model. The appendix ends with an example which is meant to illustrate that the conditions, in particular, the condition on bounded allocation differences, is not easily dispensed with.

Additional Example and Description of Programs for: "Using Asset Prices to Measure the Persistence of the Marginal Utility of Wealth"

This supplement contains an additional example that illustrates Proposition 4 in the paper. We also describe the programs and data used to derive the empirical results.
