Protectionism, recession, recovery: looking back and looking forward

In thinking of protectionism, the Great Depression, the Great Recession, and what might come next, here are two interesting angles.

Governments with their backs against the wall

 

Ideally, stabilisation using monetary and fiscal policy, alongside actions by the private sector, should restrain the decline in consumption, and yield conditions which are not too harsh for households. At the time of the Great Depression, much less was known of economics. Pegging the currency to gold meant giving up monetary policy autonomy; the US Fed succumbed to contractionary monetary policy once you take into account the closure of banks; the fiscal policy response at the time was miniscule.

It has been argued that the the Smoot-Hawley Tariff Act came about in the US in June 1930, at a point in time where the politicians were coming under enormous pressure to do something. After seven months of inaction by macro policy, with mounting difficulties in the economy, the politicians succumbed to protectionism. This appears to have been of decisive importance in sending the world down the destructive path of competitive trade barriers and cometitive devaluation. In the graph made famous by Barry Eichengreen and Kevin H. O'Rourke, at month 7 there was almost no decline in world trade. Douglas A. Irwin is worth reading on this.

Protectionism adversely impacts the recovery

 

Greg Mankiw and Scott Sumner point out one more channel through which Smoot-Hawley damaged prospects for the recovery was through the impact of protectionism on confidence.

The private sector saw protectionism as symbolising government backing away from responsible thinking in economics, and responded with a weakening of investment demand. This served to exacerbate the downturn.

Will this time be different?

 

The bulk of world GDP is now endowed with inflation targeting central banks. This ensures that monetary policy will be counter-cyclical: under bad business cycle conditions, inflation forecasts will drop below targets, and central banks will use every trick in their book to push inflation back up to target.

Fiscal policy has responded well this time around, thanks to better understanding of business cycles when compared with 1929. But there is little headroom to go further.

The world has as little ability to rein in some players engaging in competitive devaluation (e.g. China) today, as was the case in 1930. But with the bulk of world GDP being placed with inflation targeting central banks, the extent to which such tactics will be used will be relatively limited.

So far, we have had an upsurge of protectionism, but nothing on the scale of that seen from 1930 onwards. This could partly reflect the dramatic actions which governments have undertaken through monetary and fiscal policy, through which politicians have been able to reduce the domestic political difficulties that go along with business cycle downturns. But if, in coming months, the world economy remains mired in recession, then we could get fresh pressure to do something. In a recent voxEU post, Jeffrey Frieden points out that the path of adjustment of macroeconomic imbalances and currency distortions will involve political pain along the way, which could spillover into protectionism.

Some protectionist decisions could reflect bargaining tactics aimed at getting China to reduce or end their market manipulation of the currency market. But if there is an upsurge of protectionism beyond this, it will further damage the recovery by hurting investment, giving a spiral of bad economy -> protectionism -> reduced investment demand -> worse economy.

  1. Sir I am again posting my comment after a correction:

    Dear Sir,
    Had little difficulty in understanding the article. If China can devalue its currency to benefit its exports (I hope I am right up to this point) then what prevents others from doing so and how China could be forced to reverse this policy ?

    Wishing you and your family a very happy New Year 2010.

  2. Dear Mr. Shukla,

    Hope you will find this blog to be useful. A lot of these issues surface often here.

    In a nutshell, the tradeoff is as follows. All modern economies move into substantial capital account openness. Burma can be closed, India cannot. Once there is substantial capital account openness, the pursuit of currency policy comes at the expense of monetary policy.

    So every modern country has to choose between the short-term goal of stabilisation through monetary policy versus export promotion through exchange rate mercantalism.

    The bang-for-the-buck in exchange rate mercantalism is limited in the medium term, because we do not control the real rate in the medium term. RBI buys dollars to try to subsidise exporters -> local interest rates go down -> in the medium term inflation goes up -> exporters lose the subsidy. So the gains for exporters are only in the short run.

    In short, the choice to make is between stabilising the macroeconomy through monetary policy vs. a short-term gain from export promotion.
