In this paper, we examine the effect of Section 1031 tax deferred payment on Texas agricultural land price. To analyze the effects, we estimate the market equilibrium price function using the dynamic panel model and Texas agricultural land sales for 1965-2007. We argue that Section 1031 increases both demand and supply of agricultural land by its tax reducing effect. Our empirical estimation shows that Section 1031 decreases the market price which means the supply curve shifted to the right more than the demand curve.
