Undergraduate econometrics syllabus

This video provides an overview of the subject of econometrics at undergraduate level, and surveys the topics which this online course will cover.

Also, see a part of the transcript below.

In this video I want to provide a description of the syllabus which we are going to cover in the undergraduate course. So at the back of our minds within the undergraduate course, and actually at the graduate level as well. The idea is that there is some population and within the population there might be countries, there might be individuals, there might be firms. And the idea is that we don't actually have the whole population data set you only have a sample from that population. So perhaps we have the just the figures which I'm highlighting here in purple, and these individuals form a sample data set. And the idea with econometrics is that we want to use some sort of tool, some sort of statistical or mathematical tool on that sample, to enable us to make some inference about what's going on in the population or to make some estimation of some sort of population parameter. So what exactly do I mean by estimating the population parameter? So there might be a relationship between the level of wage an individual obtains and their level of education, which is given by the relationship here which I've drawn mathematically. And the idea here is that the coefficient beta might represent the effect of one-year extra of education on an individual's average level of wages. And that would be defi

What is econometrics?

This video provides an introduction to the subject of econometrics, using a few examples to explain the sorts of question which are likely to be encountered.



In this video I want to talk about what actually do we mean by econometrics. So econometrics is in general a statistical tool set which helps us to evaluate some sort of relationship of interest. An example might be we're interested in, for individuals, what is the effect of an individual's level of education on the average wage which that individual might expect to obtain. So if an individual's level of education increases we might expect that the level of wages which an individual obtains on average might increase. So if I was to plot a graph of the level of education of individuals on the x-axis, against the wages which a group of individuals have obtained on the y-axis, then we might hope to see some sort of positive correlation between these two variables. That's not to say that is necessarily a causal relationship only that there is some sort of positive relationship between these two variables. Econometrics help us to quantify this degree of correlation by in a sense drawing a line through the centre of all those points. And by drawing a line through the centre of all those points we are hoping to capture what is the average effect of education on wages. So on average an individual who has years of education, might expect to obtain a wage which is let's say four hundred dollars. Whereas an individual perhaps if

Econometrics vs hard science

This video describes the similarities and differences between econometrics and 'hard' science. The example given is attempting to quantify the effect of military spending on lifetime income. A great paper on this subject is given by Angrist (1990), who uses IV estimation to estimate the effect.

Quite excitingly (for me at least), I am about to publish a whole series of new videos on Bayesian statistics on youtube.

Natural experiments in econometrics

This video provides an example of a 'Natural Experiment' and how they can be put to use in econometrics. The example given is how the Vietnam was lottery draft system was used as a means to estimate the effect of military participation on lifetime earnings in Angrist's 1990 seminal paper.
