Large Sample Theory Geography. Ch. 36: Large Sample Estimation and Hypothesis Testing 2113 Abstract Asymptotic distribution theory is the primary method used to examine the properties of econometric estimators and tests. We present conditions for obtaining consistency, detailed introduction to large sample theory, focusing on modes of convergence, techniques for establishing asymptotic normality, and applications in parametric and non-parametric estimation and testing. Large sample theory for bootstrap approximations will be introduced as well..

This is a good book on large sample theory with lots of examples and background material. It is suitable for graduate level or researchers trying to get to grips with this tricky topic. The idea is that given a reasonably large dataset, the properties of an estimator even when the sample size is finite are similar to the properties of an estimator when the sample size is arbitrarily large. In these notes we focus on the large sample properties of sample averages formed from i.i.d. data.
