MILAN – The global economy is experiencing a major growth challenge. Many advanced countries are attempting to revive sustainable growth in the face of a decelerating global economy. But the challenges across countries are not the same. In particular, the tradable and non-tradable parts of a range of economies differ in important ways.
In the non-tradable sector (60-70% of the economy in advanced countries), the main growth inhibitors are weak demand, as in the United States following the financial crisis, and structural and competitive impediments to productivity, as in Japan. In the tradable sector, growth depends on a country’s productivity relative to incomes and competitiveness. At the global level, there can also be a shortage of aggregate demand on the tradable side.
