The experiment in macroeconometrics
نویسندگان
چکیده
This paper examines the experiment in macroeconometrics, the different forms it has taken and the rules that have been proposed for its proper conduct. Here an ‘experiment’ means putting a question to a model and getting an answer. Different types of experiment are distinguished and the justification that can be provided for a particular choice of experiment is discussed. Three types of macroeconometric modelling are considered: the Cowles (system of equations) approach, the vector autoregressive model approach and the computational experiment.

Model Evaluation in Macroeconometrics: from Cowles foundation to DSGE models
This paper reconsiders the developments of model evaluation in macroeconometrics over the last forty years. Our analysis starts from the failure of Cowles foundation models. The different diagnosis of this failure are then analyzed to classify them in two groups: explanations related to problems in the theoretical models that lead to problems in the identification of the relevant econometric mo...
متن کاملPersonal Research Statement
I am a macroeconomist with both theoretical and empirical interests. My research concentrates on two main areas: monetary economics and applied macroeconomics or macroeconometrics. I also have a few less closely related papers resulting from ideas generated while working on my core research areas. Section 1 of this research statement focuses on my work in monetary economics. I start by providin...
متن کاملThe Use of the New Macroeconometrics for Policy Formulation
Could a credible plan to reduce the government budget deficit stimulate the economy in the short run? If so, what speed of deficit reduction is required? Should the central bank alter its responsiveness to the state of the economy because of a credible deficit-reduction plan? Should the path of deficit reduction be contingent on the future state of the economy? These particular questions-all of...
متن کاملTime Series Simulation with Quasi Monte Carlo Methods
This paper compares quasi Monte Carlo methods, in particular so– called (t,m, s)–nets, with classical Monte Carlo approaches for simulating econometric time–series models. Quasi Monte Carlo methods have found successful application in many fields, such as physics, image processing, and the evaluation of finance derivatives. However, they are rarely used in econometrics. Here, we apply both trad...

Counterfactual Analysis in Macroeconometrics: An Empirical Investigation into the Effects of Quantitative Easing This paper is concerned with ex ante and ex post counterfactual analyses in the case of macroeconometric applications where a single unit is observed before and after a given policy intervention. It distinguishes between cases where the policy change affects the model’s parameters an...
