As Conceived By The Founders Of The Econometric Society, Econometrics Is A Field That Uses Economic Theory And Statistical Methods To Address Empirical Problems In Economics. It Is A Tool For Empirical Discovery And Policy Analysis. The Chapters In This Volume Embody This Vision And Either Implement It Directly Or Provide The Tools For Doing So. This Vision Is Not Shared By Those Who View Econometrics As A Branch Of Statistics Rather Than As A Distinct Field Of Knowledge That Designs Methods Of Inference From Data Based On Models Of Human Choice Behavior And Social Interactions.
