Ovire za rast niso v ekonomiji, pač pa v politiki in ideologiji

Joseph Stiglitz:

The world faces a deficiency of aggregate demand, brought on by a combination of growing inequality and a mindless wave of fiscal austerity. Those at the top spend far less than those at the bottom, so that as money moves up, demand goes down. And countries like Germany that consistently maintain external surpluses are contributing significantly to the key problem of insufficient global demand.

There are huge unmet global needs that could spur growth. Infrastructure alone could absorb trillions of dollars in investment, not only true in the developing world, but also in the US, which has underinvested in its core infrastructure for decades. Furthermore, the entire world needs to retrofit itself to face the reality of global warming.

The only cure for the world’s malaise is an increase in aggregate demand. Far-reaching redistribution of income would help, as would deep reform of our financial system – not just to prevent it from imposing harm on the rest of us, but also to get banks and other financial institutions to do what they are supposed to do: match long-term savings to long-term investment needs.

But some of the world’s most important problems will require government investment. Such outlays are needed in infrastructure, education, technology, the environment, and facilitating the structural transformations that are needed in every corner of the earth.

The obstacles the global economy faces are not rooted in economics, but in politics and ideology. The private sector created the inequality and environmental degradation with which we must now reckon. Markets won’t be able to solve these and other critical problems that they have created, or restore prosperity, on their own. Active government policies are needed.

That means overcoming deficit fetishism. It makes sense for countries like the US and Germany that can borrow at negative real long-term interest rates to borrow to make the investments that are needed. Likewise, in most other countries, rates of return on public investment far exceed the cost of funds. For those countries whose borrowing is constrained, there is a way out, based on the long-established principle of the balanced-budget multiplier: An increase in government spending matched by increased taxes stimulates the economy. Unfortunately, many countries, including France, are engaged in balanced-budget contractions.
