The World Economy’s Impossible Demand
Policymakers worldwide continue to focus on short-term demand management in the hope of resurrecting pre-2008 growth rates. But supply-side factors indicate that demand stimulus cannot be sustained over the longer term – or even serve as an effective short-term policy.
WARSAW – The global economy’s glory days are surely over. Yet policymakers continue to focus on short-term demand management in the hope of resurrecting the heady growth rates enjoyed before the 2008-09 financial crisis. This is a mistake. When one analyzes the neo-classical growth factors – labor, capital, and total factor productivity – it is doubtful whether stimulating demand can be sustainable over the longer term, or even serve as an effective short-term policy.
Consider each of those growth factors. Over the next 15 years, demographic changes will reverse, or at least slow, labor-supply growth everywhere except Africa, the Middle East, and South Central Asia. Europe, Japan, the United States, and eventually China and East Asia will face labor shortages.
Although large-scale migration from labor-surplus regions to deficit regions would benefit recipient economies, it would almost certainly trigger popular resistance, especially in Europe and East Asia, making it difficult to support. Increasing the labor-force participation rate, especially among women and the elderly, might ease tight labor markets, but this alone would be insufficient to counter the decline in working-age populations.
