Problem Set 1: Unbiased Estimator of the Error Variance This assignment will guide you through the derivations needed to determine what is a unbiased estimator of the error variance in the context of a univariate linear regression. This assignment may be quite challenging. Good Luck! Consider the univariate linear regression model yt = α + βxt + ut , t = 1, . . . , T. (1) where the regressors are non-stochastic (fixed) and the disturbances have zero mean and are uncorrelated and homoscedastic

Econometric Analysis of the Daily Exchange Rate between the Dollar and the Yen By: Andrew Dupere Intro: The purpose of this model is to explain the variation in price of the USD/JPY currency pair by trying to understand how other financial markets such as stock indexes and other exchange rates affect the USD/JPY. I am personally interested in this study because I trade the USD/JPY along with many other individuals and institutions. An accurate model will provide insight how stock indexes affect

iCHAPTER 1 TEACHING NOTES You have substantial latitude about what to emphasize in Chapter 1. I find it useful to talk about the economics of crime example (Example 1.1) and the wage example (Example 1.2) so that students see, at the outset, that econometrics is linked to economic reasoning, if not economic theory. I like to familiarize students with the important data structures that empirical economists use, focusing primarily on cross-sectional and time series data sets, as these are what I cover
