Do we make choices based on income or prices?

/0 Comments/in /by

Last time we noted the following regarding thinking about NGDP level targeting:

To understand what is going on we need to ask what expectations are being “set”, what is the “target” and how do these reflect what a central bank can “do”?

Expectations: We know they can be adaptive (backward looking) or rational (forward looking), but what do they refer to? Are people making choices based on expected prices, or are they making choices based on expected incomes? Do they view shocks as permanent or temporary?

Target: Is the goal to anchor the price level, or to anchor the level of expected nominal income growth? Is it to limit variability in prices and output?

What they do: If a central bank wants to increase prices can it, if it wants to increase nominal incomes can it?  If they can do both, how does this influence their ability to “close output gaps”?

Here I want to discuss a little more about expectations.

Small town dynamics

/0 Comments/in , , /by

By international standards, New Zealand is a small town economy. True, Auckland now has more than 1.5 million people, but by global metrics this is not very large. In 2010 there were 449 cities with more than 1 million residents, and Auckland was ranked 307 in terms of population. Small beans indeed – even if Auckland is four times as large as the next two biggest cities in New Zealand.

So how does this small size influence outcomes for New Zealanders?

How does nominal income targeting work?

/0 Comments/in , /by

Thanks to Dr. Kirdan Lees for prompting me to write today’s post. Today’s topic of discussion is nominal income targeting.

What is nominal income targeting? 

Nominal income targeting is usually viewed as an alternative monetary strategy to inflation targeting, and has never explicitly been applied in practice by any central bank. However, there is an overwhelming amount of literature discussing this monetary policy tool and how it compares to the flexible (inflation) targeting.

Land taxes and the Zero-Carbon Act

/0 Comments/in , /by

The Zero-Carbon Act means New Zealand is to accelerate the transition to an economy that uses fewer carbon-fossil based energy sources. Given what we know about the problems of global warming, a future in which most energy is renewable is to be welcomed. (As a life-long bicycle commuter, I also hope this future involves fewer cars, to raise the probability I shall live long enough to see it.) 

However, such a transition may require public investment and redistribution to help certain groups who suffer disproportionately from the changes – implying that feasible externality taxes may not be enough. If so there may be a case for land taxes to help fill this gap.

Randomized control trials and economic models: friends or foes?

/0 Comments/in , , , /by

Randomized control trial (RTC) studies are getting more and more attention among policymakers in the last few decades. In addition, the RCT is one of the core experimental methodologies used by the recent nobel prize laureates in economics Duflo, Kremer and Banerjee. 

Given the excitement around these methods, Chicago University has recently run the IGM Economic Experts Panel asking economic experts on whether the “ Randomized control trials are a valuable tool for making significant progress in poverty reduction”. The results of the poll are summarized in the graph below. 

The chart above highlights respondents’ agreement distribution. What struck me most from the results was Angus Deaton’s strong disagreement with the statement – especially given that he is an expert in the field.

Measuring “OK Boomer”

In a sense OK Boomer has a history as long as the lives of Baby Boomers themselves – at least if we relate such things to the overlapping generations models in economics.
