This study provides a partial equilibrium approach to quantifying the effect of the Highly Pathogenic Avian Influenza (HPAI) outbreak that occurred in the United States in late 2014 and early 2015. The quarterly model provides an estimate of egg prices that would have occurred over this period without the HPAI outbreak. This research also provides sensitivity analysis around the estimated retail demand elasticity based on a review of the literature surrounding the retail demand for eggs in the United States.
