This paper examines a contractual settingwith unverifiable investment and a durable trading opportunity, in which trade can take place in any one of an infinite number of periods. The contractual setting features cross-investment, meaning that the seller’s investment affects the...

This paper examines a class of contractual relationships with specific investment, a non-durable trading opportunity, and renegotiation. FurtheringWatson’s (2007) line of analysis, trade actions are modeled as individual and trade-action-based option contracts are explored. Simple tools...

This paper examines a class of contractual relationships with specific investment, a non-durable trading opportunity, and renegotiation. Trade actions are modeled as individual and trade-action-based option contracts (“non-forcing contractsâ€) are explored. The paper identifies an...

This paper proposes a nonparametric test for conditional independence that is easy to implement, yet powerful in the sense that it is consistent and achieves root-n local power. The test statistic is based on an estimator of the topological "distance" between restricted and unrestricted...

In the classic Arrow-Debreu model, the existence of money is not accommodated. However, using trading post market segmentation and requiring budget balance in each pair-wise transaction the model can converge to monetary equilibrium. Uniqueness of the common medium of exchange (commodity money)...

The paper develops the Öxed-smoothing asymptotics in a two-step GMM framework. Under this type of asymptotics, the weighting matrix in the second-step GMM criterion function converges weakly to a random matrix and the two-step GMM estimator is asymptotically mixed normal. Nevertheless, the Wald...

The federal government offers an array of tax-based aid student aid programs designed to lower the cost of postsecondary attendance. Many taxpayers are eligible for more than one program, yet they are limited to one program per student per year. Analyzing a unique panel dataset of individual...

We develop a new asymptotic theory for autocorrelation robust tests using a vector autoregressive (VAR) covariance matrix estimator. In contrast to the conventional asymptotics where the VAR order goes to infinity but at a slower rate than the sample size, wehave the VAR order grow at the...
