The elementary theory of the Frobenius automorphisms
, 2004
"... We lay down some elements of a geometry based on difference equations. Various constructions of algebraic geometry are shown to have meaningful analogs: dimensions, blowingup, moving lemmas. Analogy aside, the geometry of difference equations has two quite different functorial connections with ordin ..."

of discrete valuation rings. The central application and motivation is the determination of the elementary theory of the class of Frobenius difference fields (algebraically closed fields of characteristic p> 0,
An elementary theory of comparative advantage
 Econometrica
"... Abstract. Comparative advantage, whether driven by technology or factor endowment, is at the core of neoclassical trade theory. Using tools from the mathematics of complementarity, this paper o¤ers a simple, yet unifying perspective on the fundamental forces that shape comparative advantage. The ma ..."

The Elementary Theory of Dedekind Cuts
"... this article we do the model theoretic groundwork of the first order theory of cuts, relative to a given ominimal structure expanding real closed fields. This means the following. Let M be an ominimal structure in the language L , expanding a real closed field. Let D be a new unary predicate and l ..."

"... Transfer theorem: Let θ be an elementary statement about fields. Set A(θ) = {p ∈ P (Q)  θ is true in Fp} S(θ) = {σ ∈ Gal(Q)  θ is true in ˜ Q(σ)} Then A(θ) has a Dirichlet density δ(A(θ)), S(θ) is Haar measurable and δ(A(θ)) = ..."

Better Schools Matter? Parental Valuation of Elementary Education,” Quarterly
 Journal of Economics
, 1999
"... The evaluation of numerous school reforms requires an understanding of the value of better schools. Given the difficulty of calculating the relationship between school quality and student outcomes, I turn to another method and use house prices to infer the value parents place on school quality. I lo ..."

look within school districts at houses located on attendance district boundaries; houses then differ only by the elementary school the child attends. I thereby effectively remove the variation in neighborhoods, taxes, and school spending. I �nd that parents are willing to pay 2.5 percent more for a 5
