A report by Open Europe argues that for the UK the cost of Brexit would be minor. The benefits might be minor as well. For interest groups could make it hard to reap the potential benefits of newly gained flexibility. … the path to prosperity outside the EU lies through: free trade and opening up to low cost competition, maintaining relatively high immigration (albeit with a different mix of skills), and pushing through deregulation and economic reforms in areas where the UK has...

In his blog, Ben Bernanke discusses the merits of “helicopter drops” as a monetary policy tool. [A] “helicopter drop” of money is an expansionary fiscal policy—an increase in public spending or a tax cut—financed by a permanent increase in the money stock. … the Fed credits the Treasury … in the Treasury’s “checking account” at the central bank, and those funds are used to pay for the new spending and the tax rebate. … it should influence the economy through a number of channels, making it...

Key figures from The Panama Papers.

The Economist reviews a new book—“Peak”—by Anders Ericsson and Robert Pool: Most notable is the “10,000 hour rule”: the idea that anyone can become an expert if they put in the time, a theme popularised by writers like Malcolm Gladwell. At the heart of Mr Ericsson’s thesis is that there is no such thing as natural ability. Not for Mozart, nor for Garry Kasparov. Traits favourable to a task, such as perfect musical pitch, help at the outset but confer no advantage at higher levels. Rather,...

A new book on inequality by Branko Milanovic adopts an international perspective. The Economist reviews the book: Like Mr Piketty, he begins with piles of data assembled over years of research. He sets the trends of different individual countries in a global context. Over the past 30 years the incomes of workers in the middle of the global income distribution—factory workers in China, say—have soared, as has pay for the richest 1% (see chart). At the same time, incomes of the working class...

The Economist reports about “outcome switching”—promoting empirical evidence collected in the context of a specific hypothesis test (that didn’t succeed) as support for a different hypothesis. Outcome switching is a good example of the ways in which science can go wrong. This is a hot topic at the moment, with fields from psychology to cancer research going through a “replication crisis”, in which published results evaporate when people try to duplicate them.

The Economist reports that regulation catches up with peer-to-peer lending: Meanwhile, a case working its way through the courts may subject P2P loans to state usury laws, from which banks with a national charter are exempt. That would prevent the P2P firms from lending to the riskiest borrowers in much of America. In addition, the Consumer Financial Protection Bureau, a federal agency, announced this month that it would begin accepting complaints about P2P consumer lending. Rates of...

The Economist reports about initiatives by commercial and central banks that aim at adopting the blockchain technology. For commercial banks, distributed ledgers promise various advantages—but they also cause problems: Instead of having to keep track of their assets in separate databases, as financial firms do now, they can share just one. Trades can be settled almost instantly, without the need for lots of intermediaries. As a result, less capital is tied up during a transaction, reducing...

In the Pro Market blog, (previous) industry insiders describe the extent of rent seeking activities in pharmaceutical companies (bribing doctors), finance (exploiting information asymmetries vis-à-vis clients).

In his blog, Ben Bernanke discusses the merits of longer-term interest rate targeting as a monetary policy tool. A lot would depend on the credibility of the Fed’s announcement. If investors do not believe that the Fed will be successful at pushing down the two-year rate … they will immediately sell their securities of two years’ maturity or less to the Fed. … the Fed could end up owning most or all of the eligible securities, with uncertain consequences for interest rates overall. On the...
