Intertemporal Capital Asset Pricing Model (ICAPM). Comments on the CAPM and ICAPM. Arbitrage Pricing Theory (APT). develop, on my website soundofheaven.info research /Papers . Intertemporal Capital Asset Pricing Model (ICAPM) Article (PDF Available) in Journal of Economic Behavior . What Cochrane does in Asset Pricing, very intelligently, convincingly, with great.

Regards Conwyn. The left hand variable is the forward-spot spread in the Fama Bliss regression. I will block comments with insulting or abusive language. The cross-sectional regression with an intercept sets the average pricing error to zero. In my case, I first began with John's lecture notes and nice! This online course is a wonderful companion to the classic textbook, Asset Pricing, by you, Professor Cochrane.

A risk free asset is on the conditional frontier. It is only on the unconditional frontier if it is constant. If the risk free rate is not constant, it is not of this form. The frontier is a line in mean-standard deviation space, but a parabola in mean-variance space. This is really the same question. Put another way, the unconditional mean-variance frontier will not intersect the vertical axis. This happens all the time. The 3 month T bill rate is nominally conditionally risk free. Yet a plot of the unconditional mean-variance frontier will not intersect the vertical axis since the T bill rate varies over time.

Even if there is a conditionally risk free rate, if it is not constant, the unconditional representation will need a zero-beta rate. Unless, of course, everything is i. Intuitively, there are no arbitrage portfolios of stocks — portfolios that dominate in every state of nature.

Problems like this generate arbitrage bounds in option pricing problems. In option pricing, though, there are strictly dominating portfolios; a call option is better in every state of nature than the portfolio that holds the stock and borrows the strike payment. No, it has to be the risk free rate, or a zero-beta rate. The question is whether we can do this on the right hand side too. Can we write the CAPM in terms of an excess return on the right hand side?

Once posed, you can see that the answer is no. Betas are not linear in the denominator. Though the riskiness of the T bill rate does not matter for the left hand side, it does for the right.

If the series is i. Of course, you can calculate standard errors without mean zero, and without i. The general formula: Yes, even if returns are predictable.

Betas add in the left hand variable, but not in the right hand variable. The GRS test requires factors that are returns. Pricing errors can be correlated with betas with time-series regressions. Not with a cross-sectional OLS regression. Cross-sectional regressions set the right hand variable — betas — orthogonal to the error term — alphas. They can again be correlated with a GLS cross-sectional regression. The cross-sectional regression with an intercept sets the average pricing error to zero.

The pricing error of the equally weighted portfolio is, of course, the average pricing error. This regression does not necessarily pass through the origin or risk free rate. It is best to reserve d for the d matrix, and the two are no longer equal. The general formula?? T S21 S22 The bottom right element is thus 1 S Next, we want to test the pricing errors.

Since the E f moment is zero in every sample, the last K diagonal elements of cov gT are zero. This is natural, since the E f moments are set to zero in each sample.

A factor that is a return will have a single regression beta of one on itself, but will also have nonzero single regression betas on the other correlated factors.

This intuitively appealing procedure is exactly a cross-sectional regression. But it would be ad-hoc, not ML. You might want to exercise American puts early.

Thus, we multiply both terms of the Black-Scholes formula by 1, which does not change them. From Go back to the derivation on p. However, b The results will depend on the information set you choose. Fama and Bliss See the term structure chapter for notation. Now, to express the same idea formally.

This should remind you of the Campbell Shiller identity that you can discount a stock price by its ex-post returns. The left hand variable is the forward-spot spread in the Fama Bliss regression.

The right hand term is the change in one year yield, and the holding period return on two year bonds. The left hand side is 1 — forward spot on forward spot. See Fama and Bliss for the general case — longer maturities.

Imagine simulating out a huge number of data points from the VAR. Then, take only the return data, ignoring data on other variables. Run a regression of returns on lagged returns. You just have to go through and do for prices what we did for returns.

The equation for prices is, from Now, look through the cases on p. Returns are i. Bond prices are stationary, because the only reason a bond price changes is that interest rates change. You could see this in the VAR too. Using the numbers on the top of p. Here we go again. You need a negative correlation between expected return and actual return shocks to generate uncorrelated returns.

First, the long run variance of a stationary series must be zero. See Hodrick for lots of calculations like this. Many models predict too much variation in the conditional mean discount factor, or too much interest rate variation. This problem guides you through a simple example. But if you want to start with review of regular calculus, I highly recommend "Applied Intertemporal Optimization" by Klaus Walde This e-book is free of charge and available at http: In my case, I first began with John's lecture notes and nice!

And I could get the intuition "What's going on? Then I read Walde's and finally Chang's. In this way, now I can use stochastic calculus in my research.

Hope this helps, Mizuki. Module 1 Homework 1 [practice]: Horizon Effects in Returns: On canvas. It is showing urls back to canvas. I have tried with edge, firefox and chrome.

Hi Nina I created a test. I can not show my example because this input box objects to it but in essence your server is missing a body statement. Regards Conwyn. The canvas. Hi Nina It is still not fixed on the quiz. The quiz looks fine as soon as you open it fresh. If you have already attempted the quiz earlier before it was fixed , the best is to access the course from a new profile. Hi Nina I am proceeding through the course slightly slower than a snail almost finished module 3.

Does the course continue to be available into the immediate future approximately snail units. Are there any plans to produce a transcript of what John delivers.

Comments are welcome. Keep it short, polite, and on topic.

Thanks to a few abusers I am now moderating comments. I welcome thoughtful disagreement.

I will block comments with insulting or abusive language. I'm also blocking totally inane comments. Try to make some sense.

I am much more likely to allow critical comments if you have the honesty and courage to use your real name. Friday, September 8, Online Asset Pricing is back! Posted by John H. Cochrane at 5: Finance , Thesis topics.
