David Andolfatto: Macro Mania

David Andolfatto, Vice President of the St. Louis Fed, created MacroMania as a resource for people wanting a better understanding the Fed’s marcoeconomic policy. His commentary is incisive and thorough, particularly his thoughts on Bitcoin and blockchain technology.

Inflation and Unemployment (Part 2)

In my previous post (Inflation and Unemployment), I reviewed what I thought was a fair characterization of the way the Federal Reserve Board staff organize their thinking about inflation and unemployment, as well as how this view of the world was at least partly responsible for the "hawkish" overtone of current Fed policy. I also suggested that the inflation and unemployment dynamic might be better understood through the lens of an alternative theory that emphasized the supply and demand...

Inflation and unemployment

The FOMC decided on March 21 to increase the target band for the federal funds rate by 25 basis points, to a range of 1.50-1.75%. This despite inflation running persistently below the Fed's 2% target, only moderate wage growth, and inflation expectations firmly anchored. What is the FOMC thinking here? To be more precise, what is the dominant view within the FOMC that is driving the present tightening cycle? Remember, the FOMC is made up of 12 regional bank presidents plus 7 board of...

What anchors inflation?

Conventional wisdom is that a central bank can anchor the long-run rate of inflation to a target of its own choosing. This belief is evident where ever a government has charged its central bank with a "price stability" mandate (commonly interpreted nowadays as keeping a consumer price index growing on average at around 2% per annum over long periods of time). What exactly is the mechanism by which a central bank is supposed to control the long-run rate of inflation (the growth rate of the...

The recession of 2012-13 and the taper tantrum

I admit this is a rather strange title for a post, but bear with me. Every once in a while I reflect back on the so-called "taper tantrum" event in the summer of 2013 when Fed Chair Ben Bernanke made an off-the-cuff remark that the FOMC was thinking of maybe slowing down the pace QE3 asset purchases (see here). The stock market had a temporary sell-off, which turned out to be no big deal. What I find more interesting is how long bond yields rose sharply and persistently. Even more...

U.S. GDP Expenditure Components

One way to decompose the GDP is in terms of its expenditure components, Y ≡ C + I + G + NX. I like to write "≡" instead of "=" to remind myself that this decomposition is measurement, not theory.   In what follows, consumption is measured in terms of nondurables and services only--I add consumer durables with private investment. The data is inflation-adjusted, quarterly, and I report year-over-year percent changes. I'll start with recent history (since 2010) and then later look at a longer...

Fiscal theories of the price-level

This post is me thinking out loud about how fiscal considerations may influence the price-level.  The question of what determines the price-level is an old one. It's a question that economists struggle with to this day. To begin, what do we mean by the price-level? Loosely, the price-level refers to the "cost-of-living," where cost is measured in units of money. Living refers to the flow of services consumed (destroyed) for the purpose of survival/enjoyment. (Note that the cost-of-living...

Blockchain: what it is, what it does, and why you probably don’t need one

Dilbert - by Scott AdamsInterest in blockchain is at a fever pitch lately. This is in large part due to the eye-popping price dynamics of Bitcoin--the original bad-boy cryptocurrency--which everyone knows is powered by blockchain...whatever that is. But no matter. Given that even big players like Goldman Sachs are getting into the act (check out their super slick presentation here: Blockchain--The New Technology of Trust) maybe it's time to figure out what all the fuss is about. What...

Lowflation: Then and Now

The term "lowflation" was initially coined by economists at the IMF in 2014 (see here). It refers to an inflation rate that is persistently low (relative to some target) but positive. Here is what lowflation looks like in the United States: How should we think about lowflation? I've written a bit on the subject here and here. Is the phenomenon unusual? Is it something we should worry about?As it turns out, the phenomenon is not unusual even in recent U.S. monetary history. The following...

Fedcoin and blockchain

I see Campbell Harvey promoting the idea of Fedcoin here: "Bitcoin is Big. But Fedcoin is Bigger." I'm not sure I agree with his pitch for the idea.Let's start with Harvey's claim that "Bitcoin and other cryptocurrencies are based on a complicated technology known as blockchain, which acts like a digital ledger of all transactions completed with the currency." Complicated? Well, yes and no. As I explain here "Why the blockchain should be familiar to you," there's a sense in which...

My perspective on the Bitcoin Project (collected works)

It's true, I really did say that.It's Christmas time and I'm in a giving mood. So I thought I'd collect all my writings and talks related to Bitcoin and blockchain in one easy-to-access spot. Like many people, I first took notice of Bitcoin in 2013, after its price soared to over $1000, before plummeting significantly. Thank goodness I didn't buy any back then (D'oh!). Many economists dismissed the phenomenon as just another bubble/scam. This was my initial instinct as well, but after...
