To RMB or not to RMB? Lessons from Currency History

China is the world’s largest trader and (on a purchasing power parity basis) is about to surpass the United States as the world’s largest economy. China already accounts for about 10% of global trade in goods and services, and over 15% of global economic activity.

So, as China takes its place as the biggest economy on the globe, will its currency, the renminbi (RMB), become the most widely used international currency as well? Will the RMB supplant the U.S. dollar as the leading reserve currency held by central bankers and others, or as the safe-haven currency in financial crises?

Do U.S. Households Benefit from the Great Moderation?

Something odd has happened to the U.S. economy over the past 30 years. Aggregate income (measured by real GDP) has become more stable (even including the 2007-2009 Great Recession). But, at the household level, the volatility of income has gone up. Put differently, families face greater income risk than in the past despite generally fewer or smaller economy-wide wobbles. What should we make of this?

How much is our distant future worth?

In the first Superman movie, released in 1978, Lex Luthor, the supervillain played by Gene Hackman, buys up large swaths of real estate in the deserts of eastern California and Nevada. His plan is to hijack a nuclear missile and use it to cleave off coastal California into the Pacific Ocean, leaving him with newly valuable beach-front property. Well, maybe all Lex really needed was patience, not a nuclear device...

Should I buy or should I sell?

The U.S. stock market dropped last week, but the S&P 500 index is still 13% above its year-ago level and a whopping 181% above its March 2009 trough. If you are an investor, your goal is to buy low and sell high. Looking at the stock market, what would we do today? Are prices too high? Are they too low? Or, are they just right?

Has paper money outlived its purpose?

Serious people have been suggesting that we think hard about eliminating paper currency. Paper money facilitates criminality and creates the zero lower bound (ZLB) for nominal interest rates. So, why not just get rid of it and replace it with electronic money?

Inflation Expectations: How Credibility Pays Off

Monetary policymakers always worry about inflation expectations. They can’t directly observe what households and business anticipate for the future path of prices, so they construct estimates from market prices and surveys. Why do they care so much? The reason is simple: keeping inflation expectations low and stable is the first step to keeping inflation low and stable. It also makes the economy more resilient in the face of adverse shocks...

Regulating Money Market Mutual Funds: An Update

The SEC has finally acted. On July 23, the SEC issued 859 pages of new rules for the operation of some money market funds. (You can find a mercifully short description here.) To summarize our reaction: we are underwhelmed! It is hard to see how the new rules will reduce systemic risk in any meaningful way...

How big can the U.S. current account stay?

In the past few years, the U.S. current account deficit has shrunk from over 6% of GDP in mid-2006 to less than 3% today. Since these current account deficits reflect capital account surpluses, many people view them as a symptom of the problems that led to the crisis. That is, funds from abroad were fueling the credit boom in the United States, which in turn fed the boom in housing prices, etc.

Over the past three decades the U.S current account has been in surplus only briefly in the first half of 1990. Since then, it has been continuously in deficit. How is it that the United States can keep borrowing without a collapse in the currency or a surge in borrowing costs? Is there some sort of limit?

Truth or consequences: Ponzi schemes and other frauds

In the financial world, the real scandal is often what’s legal, but you still have to watch out for fraudsters. If you don’t pay the costs of screening and monitoring your financial counterparties, you may lose your house.

The never-ending need for financial vigilance came to mind recently when we noticed that the 1920 home of Charles Ponzi was for sale in Lexington Massachusetts. It’s a very large house – 7 bedrooms, 6 bathrooms, 7000 square feet of space (650 square meters) on nearly an acre of land (0.4 hectares).(You can see a picture here.) ...

Debt, Great Recession and the Awful Recovery

Debt has been reviled at least since biblical times, frequently for reasons of class (“The rich rule over the poor, and the borrower is slave to the lender.” Proverbs 22:7). In their new book, House of Debt, Atif Mian and Amir Sufi portray the income and wealth differences between borrowers and lenders as the key to the Great Recession and the Awful Recovery (our term). If, as they argue, the “debt overhang” story trumps the now-conventional narrative of a financial crisis-driven economic collapse, policymakers will also need to revise the tools they use to combat such deep slumps...
