Abstract: Empirical studies suggest that cost-share programs are unlikely to reduce exploitation of ground water and nonpoint-source pollution. By introducing an induced irrigation technology in our model, we find theoretically that the optimal amount of irrigation water and nitrogen fertilizer increases (decreases) when the increased rate of the marginal net economic benefits from their use with an induced irrigation technology exceeds (is less than) an increase in the rate of irrigation efficiency. Our results suggest that producers should use relatively more irrigation water and fertilizer when greater quantities of high-value crops are grown because producers will adopt improved irrigation technologies for such crops.
