Only agents know their potential to generate benefits. We prove that if the more "productive" agents are also more risk-tolerant (as holds in the sample of individuals we surveyed), the principal can screen agents and bolster target efficiency by offering a choice between a nonrandom budget and a two-outcome risky budget. When, at very low allocations, the ratio of the more risk-averse type's marginal utility to that of the other type is unbounded above (e.g., as with CRRA), the first-best is approached. -- A biblical opening enlivens the analysis.
