Typos in Math of "Information and Consumption Smoothing"

[spspitze]

Small issues in the math of Information and Consumption Smoothing.

• It says

which confirms that {a_t} is a serially uncorrelated process with variance
σ^2_a=β^{−1}σ^2_ε.

when this should be β^{−2}.

• For the alternative calculation of σ^2_a, it says "σ^2_ε + ..." when I think this should be "σ^2_ε \times ...". This also should equal β^{−2}σ^2_ε

Hope this helps. Thanks.

Many thanks @spspitze . Will investigate when I have a bit of time.

(If you're willing to put in a PR that corrects those typos we would be very grateful.)
