Scott Sumner has famously proposed that the Fed stabilize monetary policy by pegging nominal GDP futures contracts in such a way to ensure that expectations for nominal income growth remain steady. For more details, see here; the merits (and demerits) of this proposal are not the subject of this post (but will be the [...]
The efficient market hypothesis says that you can’t pick out which stocks are undervalued versus which are overvalued. Likewise, I claim that you can’t pick out which restaurants are underpriced versus which restaurants are overpriced.
Think you’ve found a great company, so that their stock will outperform on a risk-adjusted basis? Nope, someone [...]
Most people are probably somewhat overconfident. Most people – myself surely included – probably typically overestimate their own talents, and they (we) are overly confident in the precision of their estimates, underestimating uncertainty.
The Efficient Market Hypothesis (EMH) was famously defined by Fama (1991) as “the simple statement that security prices fully reflect all available information.”
That is, you can’t open the Wall Street Journal, read a news article from this morning about Google’s great earnings numbers that were just released, and make money by buying Google [...]
Update: Selgin points out in correspondence and Sumner points out in comments below that, the below discussion is implicitly using variables in per capita terms.
I. Marx vs. Smith and food banks
When Heinz produces too many Bagel Bites, or Kellogg produces too many Pop-Tarts, or whatever, these mammoth food-processing companies can donate their surplus food to Feeding America, a national food bank. Feeding America then distributes these corporate donations to local food banks throughout the country.
Behavioral economists have a concept called loss aversion. It’s almost always described something like this:
“Loss aversion implies that one who loses $100 will lose more satisfaction than another person will gain satisfaction from a $100 windfall.”
– Wikipedia, as of December 2015
Sounds eminently reasonable, right? Some might say so reasonable, in [...]
Until very recently – see last month’s WSJ survey of economists – the FOMC was widely expected to raise the target federal funds rate this week at their September meeting. Whether or not the Fed should be raising rates is a question that has received much attention from a variety of angles. What I [...]
I comment on Josh Hendrickson's interesting post. While it certainly is hard for me to believe that the natural rate of interest could be negative, it's difficult to find a satisfying alternative explanation for the sustained output gap of the past seven years coexisting with the federal funds rate at the zero lower [...]
JP Koning makes the case that even if Greece were to leave the Eurozone and institute a new currency (call it the New Drachma), Athens would still not have independent monetary policy: if households and firms continue to post prices in Euros rather than New Drachmas, Greek monetary policy would not be able to [...]
