The model specification problem is perhaps the Achilles heel of applied econometrics. Rather than test down to a single model as is usually done, we estimate 72 different demand systems and use Bayesian averaging procedures over all 72 systems to generate meta estimates of the parameters (e.g.,...

Consistent aggregation assures that behavioral properties, which apply to disaggregate relationships also, apply to aggregate relationships. The agricultural economics literature is reviewed which has tested for consistent aggregation or measured statistical bias and/or inferential errors due to...

The language of economics is the language of models. Understanding the structure of this language offers many benefits. Unfortunately, the structure is ubiquitous in implementation but absent in documentation. This paper documents the structure of models in the context of the theory reduction...

One of the most important principles in any science is testing and consequently confirmation and falsification. In agricultural economics, the equilibrium displacement model is a popular modeling approach that presently is not testable and consequently cannot be confirmed or falsified. This...

Consistent aggregation ensures that behavioural properties which apply to disaggregate relationships apply also to aggregate relationships. The agricultural economics literature which has tested for consistent aggregation or measured statistical bias and/or inferential errors due to aggregation...
