Approximating the Distribution of the Instrumental Variables Estimator when the Concentration Parameter is Small. [PDF]
This paper presents a new approximation to the exact sampling distribution of the instrumental variables estimator in simultaneous equations models. It differs from many of the approximations currently available, Edgeworth expansions for example, in that

Blowup solutions and their blowup rates for parabolic equations with non-standard growth conditions
Electronic Journal of Qualitative Theory of Differential Equations, 2011 This paper concerns classical solutions for homogeneous Dirichlet problem of parabolic equations coupled via exponential sources involving variable exponents. We first establish blowup criteria for positive solutions.

"A New Light from Old Wisdoms : Alternative Estimation Methods of Simultaneous Equations with Possibly Many Instruments" [PDF]
We compare four dffierent estimation methods for a coefficient of a linear structural equation with instrumental variables. As the classical methods we consider the limited information maximum likelihood (LIML) estimator and the two-stage least squares ...
