Populist politicians, among others, have claimed in recent years that monetary policy is too easy and that it is hurting ordinary workers.   But raising interest rates is not the way to address income inequality.It is a strange claim for anyone to make, but especially for populists.  Low interest rates are good for debtors, of course, and bad for creditors. Throughout most of US history, populists have supported easy monetary policy and low interest rates, to help the little guy, against bankers, who had hard hearts and believed in hard money.

I recently visited Algeria and Morocco.  Like so many other developing countries, they are dealing with the sharp decline in global commodity prices that has taken place over the last few years.  In meetings in Algiers and Casablanca, I offered four concrete ideas for policies to help commodity-exporting countries deal with global price volatility.  The four proposals, very briefly, are: (1) hedging with options (as Mexico does), (2) commodity bonds, (3) countercyclical fiscal institutions (like Chile’s), and (4) central bank targeting of a currency-plus-commodity basket.

As the G-7 Leaders gather in Ise-Shima, Japan, on May 26-27, the still fragile global economy is on their minds.  They would like a road map to address stagnant growth. Their approach should be to talk less about currency wars and more about fiscal policy.Fiscal policy vs. monetary policyUnder the conditions that have prevailed in most major countries over the last ten years, we have reason to think that fiscal policy is a more powerful tool for affecting the level of economic activity, as compared to monetary policy.

The ITC Wednesday released its mandated report on the economic effects estimated to result from the TransPacific Partnership.  As is usual in standard trade models, the estimated welfare gains may sound small: on the order of ¼ % of income.  But that would still be way worth doing.    Furthermore the ITC study, by design, leaves out a lot.  For example, the Petri-Plummer study from the Peterson Institute estimates income gains from TPP that are twice as large, in part because it takes into account Melitz-style opportunities for  more productive firms to expand.

This is the third and final installment of an interview on the outlook for the New Year.Part 3. Forecasts for International Currency and Commodity MarketsQ – What is your forecast for the U.S. dollar? Do you think maintaining the strong dollar could ultimately help the U.S. economy, or hurt it?A – The appreciation of the dollar against the euro and the yen in 2014 was precisely what we should have expected from the economic fundamentals: the strengthening of the US recovery at the same time that the euro and Japanese economies have been slumping and the end of US monetary easing at the same time that the ECB and the Bank of Japan have redoubled their efforts at monetary stimulus.

Those worried about the future of the earth’s climate are hoping that this year’s climate change convention in Lima, Peru, December 2014, will yield progress toward specific national commitments, looking ahead to an international agreement at the make-or-break Paris meeting to take place in December 2015.The precedent of the Kyoto Protocol negotiated in 1997 is more discouraging than encouraging. It was an encouraging precedent in that countries were politically able to agree on legally binding quantitative limits to their emissions of Greenhouse Gases, to be achieved with the aid of international trading and other market mechanisms.

On October 14, the Mo Ibrahim PrizeCommittee announced, for the second year in a row, that it had not found anyone to whom to award its Prize for Achievement in African Leadership.The Prize is given to a recently-retired Executive Head of State or Government in Africa who satisfies the criteria of having been democratically elected, having left at the end of his or her constitutionally mandated term, and having demonstrated exceptional leadership.  The winner receives $5 million paid over ten years, followed by $200,000 annually for life, which makes it the world’s most valuable annually awarded prizeThe Mo Ibrahim Foundation supports other valuable activities as well, especially the annual rating and ranking of countries in the Index of African Governance, which was also released October 14.

An amazing thing has happened over the last five years.   Against all expectations, American emissions of carbon dioxide into the atmosphere, since peaking in 2007, have fallen by 12%, back to 1995 levels.  (As of 2012. US Energy Information Agency).   How can this be?   The United States did not ratify the Kyoto Protocol to cut emissions of greenhouse gases below 1997 levels by 2012, as Europe did.Was the achievement a side-effect of reduced economic activity?   It is true that the US economy peaked in late 2007, the same time as emissions.

I have arguedthat the best way to think of “black swan” events is as developments that, even though low-probability, can in fact be contemplated ahead of time.  Even if they are the sort of thing that has never happened before within an analyst’s memory, similar things may have happened before in the distant past or in other countries.What current possible shocks have probabilities that, even if fairly low, are high enough to warrant thinking about now?  Some have been discussed ad infinitum, others hardly at all.

Throughout history, big economic and political shocks have often occurred in August, when leaders had gone on vacationin the belief that world affairs were quiet.   Examples of geopolitical jolts that came in August include the outbreak of World War I, the Nazi-Soviet pact of 1939 and the Berlin Wall in 1961.  Subsequent examples of economic and other surprises in August have included the Nixon shock of 1971 (when the American president enacted wage-price controls, took the dollar off gold, and imposed trade controls), 1982 eruption in Mexico of the international debt crisis, Iraq’s invasion of Kuwait in 1990, the 1991 Soviet coup, 1992 crisis in the European Exchange Rate Mechanism, Hurricane Katrina in 2005, and US subprime mortgage crisis of 2007.
