Understanding Schmidt and Woodford on Neo-Fisherianism

I think this is roughly what is going on in their model (pdf). I'm not 100% sure I'm right. And I'm not even trying to be 100% right. I'm trying to get the intuition (reverse-engineer) for those bits of their results I find most interesting. Suppose you are really bad at algebra. You can't solve […]

Euro MOA+MOE plus Drachma MOE

Suppose your country (call it "Greece") is in recession, because there is an excess demand for money (call it "Euros"). And suppose that the Euro is both Medium of Account (prices are quoted in Euros) and Medium of Exchange (all other goods are bought and sold for Euros). Now suppose your government introduces a new […]

It’s the (absence of) trust, Simon

Simon Wren-Lewis ruins (for me) what would otherwise be a very good sensible keynesian post about Greece ("sensible keynesian" is a school of thought, to which Simon belongs) by leaving out trust. Or, if you want to be techie about it, the "time-consistency problem". If you give me one apple today, and I give you […]

Bad news on GDP vs good news on employment

Here is a macro exam question: Q. You are the New Keynesian governor of an inflation targeting central bank. Two bits of information arrive simultaneously: GDP is lower than you expected; employment is higher than you expected. Relative to what you had otherwise planned to do, how do you respond to the news? Do you […]

Thoughts on the news from Greece

This is just to record my thoughts, so I can look back on this and see what I got right and what I got wrong. Or at least, what I changed my mind about. The Euro was a mistake. I hoped (and still hope)  to see the Euro dissolved. But the Euro is now stronger […]

Bank of Canada Governors and Economic Performance: A Canada Day Celebration

Another Canada Day, another year of Confederation – we are now 148 years old– and another opportunity for taking a historical look at some economic aspects of Canada. For your Canada Day musings, I decided to take a look at economic indicators according to the tenure of Bank of Canada Governors since 1934 (the legislation […]

The Bank of Canada’s “stitch in time”

Steve Poloz is good at economics, but not always so good at finding the best metaphor. Greg Quinn says "Bank of Canada Governor Stephen Poloz said his “controversial” decision to cut interest rates in January could be compared to life-saving surgery for the economy and any resulting increase in household debt should be viewed as […]

Seigniorage transfers and runs on common currencies

Two identical countries A and B share a common (paper) currency C. The demand for currency is 5% of annual (Nominal) GDP. Suppose B decides to quit the currency union and print its own currency. There are two different ways it could do this: 1. Convert and destroy. The people in B convert their C […]

Fiscal policy and indifference about the size of government

Suppose I were totally indifferent about the size of government. Because I thought that the government was always equally good (or equally bad) at spending money as private households and firms. And not just at the margin, but everywhere. Never better, never worse, but always exactly the same. Whether G is 1% of GDP, or […]

Mark Sadowski’s correlations deserve a response

They are just simple correlations, but a sample of 34 (split into two groups) beats a sample of the one country the economist just happens to live in. Correlations of data are themselves data, and it is our job to try to interpret (or explain) the data. This is how I (tentatively) interpret those correlations: […]
