Since the credit crisis began, governments around the world have passes many stimulus packages to restart stalled economic growth. For example, today the government of Malaysia announced a second a stimulus package of US$16.3B just after announcing the first stimulus four months ago. In the US, many stimulus packages have been announced during the past and the present administrations. On Feb 13, the US Congress approved a new package of $787B which is 5.6% of GDP. The initial impact of this package will be seen in the years 2009-11. Other countries such the UK, Germany, Canada, etc. have also announced stimulus packages. I wanted to find out how these packages compare across the countries.

My research led me to a paper titled “The Size of the Fiscal Expansion: An Analysis for the Largest Countries” released by IMF last month. The following are some interesting takeaways from this paper.

Of all the large countries that have passed stimulus packages, the US stimulus is the largest in terms of GDP during 2008-10.

Comparison of Stimulus Packages in Large Countries

The US package amounts to a cumulative 4.8% of GDP during 2008-10. According to Wikipedia, the 2008 US GDP is estimated to be $14.3 Trillion. India and Italy have the lowest packages at less than 1% of their GDP.

Next to US, China has the largest stimulus. Though UK is one of the worst affected countries, the package in the same period is less than Germany’s figures.

Infrastructure spending by the US is a small portion of the overall packages. As per U.S. CBO and IMF staff estimates, just $32B will be spent on infrastructure projects in 2009 and $47B each in 2010 and 2011.Countries with high public debt have passed smaller fiscal stimulus packages (India, Italy as referenced above). Of the nine countries listed above, only Canada, U.S. and Japan are providing tax benefits to both companies and individuals. The rest of them provide tax benefit only to individuals. One common theme across these countries is that all are planning to invest more in infrastructure project.

One of the fiscal implications of the current financial crisis is the effect on funded pension plans in many OECD countries. Some of the countries’ pension fund portfolios have high exposure to equities and mutual funds. Many of the mutual funds in these countries are also heavily invested in equities.

The stripped circles in the above figure shows that 16 countries have pension fund investments in equities and mutual funds greater than 10% of GDP. The countries with high exposure to stocks are Australia, the U.S., Canada, Iceland, The Netherlands, Switzerland, Denmark, and the U.K. Of the emerging market countries South Africa, Chile, and Brazil are more exposed. Countries such as Mexico, Argentina and Norway have limited exposure to the equity markets.

In the US, the asset base of pension plans for the various government workers is huge. At the end of October 2008, the $4 Trillion assets held by these plans had fallen by roughly $1 Trillion. As these plans are defined-benefit plans, the governments will make efforts to fill the gap in the future years either by raising the contributions from current employees or by raising taxes. However this does not affect the social security plan since those assets are not invested in the markets.

If employers go under taking the defined-pension plans with them, then the Federal agency Pension Benefit Guaranty Corporation (PBGC) guarantees payment to plan participants. However this creates a huge liability for the federal government.

According to a Mercer study in the US, the pension plans of the S&P 1500 companies have lost half a Trillion $ in 2008, of which 80% was lost in the last quarter.
