But most econometric studies predict that cattle prices will peak some time in February.

One of the alternative approaches involves unit root tests and the cointegration technique in econometric studies.

Many econometric studies in recent years have supported the view that development aid has no effect on the speed with which countries develop.

There have been many econometric studies intended to quantify those gains.

There are also econometric studies using panel data on individuals' labour supply, wages and personal circumstances.

These tend to be estimated from econometric studies, with 95% confidence intervals.

For this reason, econometric studies have been used to explore actual behaviour.

Yet a variety of econometric studies have failed to prove this, Professor Borjas said.

They have initiated an econometric study that will rebut it.

In addition, he has been involved in many important applied econometric and statistical studies.
