Maximum-likelihood estimation of an agency-based structural econometric model of worker choice yields elasticities ranging from 0.413 to 1.507. These estimates are smaller than, but qualitatively similar to, those reported in Paarsch and Shearer, suggesting that their model has perhaps more general applicability than their British Columbia tree-planting example.</style></abstract></record></records></xml>
