In a sea of conservative media, two articles stood out this weekend which captures a debate that should be raging but will be quickly buried under the re-emerging neo-liberal hubris unless significant new alliances are formed. In recent weeks, as different economies are showing some signs of recovery, some key players within mainstream economics have been coming out in defence of the profession. They have been accusing critics of misunderstanding what economics is all about and saying that economists have actually saved the world. I covered some of this sort of positioning in Friday’s blog. In this blog I continue that theme but from a different angle. The conclusion is that if we want real change then “one should become more radical as one grows older”. We will see what that means as we go.

Welcome to 2010. Today, in the overcast summer that we are enduring here, in between other things I am finishing off, I was in my office reading about how mainstream economics actually saved us from a major depression over the last 2 years. Far from having to hang their heads in shame, the article indicated we had all embraced Keynes and glory be the day. I also read a counter to that which outlined what further needed to be done. I concluded neither writer really had grasped what has been going on and both would benefit from exposure to modern monetary theory. Not a lot has changed overnight. Happy new year!

The year and the decade are rapidly closing out (early evening Thursday AEST). It is been an incredible year to be an economist with some of the swings in aggregates not seen before in most of our lifetimes. The degree to which nation’s have gone backwards has been staggering. For a researcher like me it has opened up so many new lines of enquiry. I always worry that my major research angle – the study of unemployment – gives me a job as long as there are others without them. But someone has to keep the topic at the top of the agenda and that is what I have devoted my academic and public career to doing. I have also been staggered this year by the sheer audacity of the mainstream economists who went to ground when the crisis emerged because their theories were shamefully wrong – but who are now popping up again – in all their arrogance – leading the charge of the deficit terrorists and undermining the capacity of governments to fight the crisis effectively. They should have just stayed in their slime. Anyway, my final post for the year has some sad things to say … and then …

In the past, when I have advocated setting the central bank policy rate to zero and leaving it there several readers have suggested that this would set off uncontrollable asset price bubbles particularly in the housing sector. Indeed, the view among mainstream economists is that lax monetary policy in the US caused the sub-prime housing crisis. It is an intuitively attractive view for those who do not really understand how the monetary system operates and the complex distributional impacts that varying interest rates have. Today’s blog considers a US Federal Reserve research paper that has just been released which rejects the notion that “loose” monetary policy was to blame. It is an interesting research exercise.

Last weekend, the senior economics writer for the Sydney Morning Herald became a salesman. He has been seemingly recruited voluntarily into the marketing campaign for Mankiw’s economics textbooks which dominate the world supply. In his textbook the Principles of Economics, which is just palpable indoctrination, students are introduced at the outset to the 10 Principles of Economics. These principles resemble the hard sell you get from a salesperson who knows their product will not stand scrutiny but wants the commission nonetheless. But Gittins, knowing his power to influence the economic thinking among his readership, presents the principles as if they are all you need to know to understand economics. What a total con that is.

Several readers have E-mailed about the concept of a multiplier in macroeconomics particularly in light of comments I made yesterday about the current debate as to whether the deficits will be expansionary and whether it would be better to cut taxes rather than increase spending. There appears to be a lot of confusion about the most basic concepts involved so this blog seeks to address some of those issues. It is not a comprehensive literature review.

Tonight we consider the tale of two countries with some other snippets of good taste included for interest. In the last few days the Japanese government has announced the largest fiscal stimulus in its modern era (since records have been kept) while Ireland announced its 2010 budget which has been characterised as the harshest in the republic’s history. Both countries are mired in recession with only the most modest signs of any recovery. So on the face of it this is one hell of a juxtaposition. What gives?
