Suggested Answer: C

In the linear model, the bi's represent the unknown p parameters. The estimates for these unknown parameters are chosen so that, on average, the model provides a reasonable estimate of a person's income based on age and education. In other words, the fitted model should minimize the overall error between the linear model and the actual observations. Ordinary Least Squares (OLS) is a common technique to estimate the parameters

I think it might be the Rate Anticipation with Maturity Mismatch. We discussed it in class, but I'm not 100% sure if it specifically applies to both investors and speculators.

The answer has to be in one of the categories shown in Exhibit 1, since that's what the question is asking about. I'm leaning towards C, Keywords, but I'll double-check the other options just to be sure.
