The term “secular stagnation” was coined by Harvard economist Alvin Hansen in the 1930s. Secular stagnation refers to a situation of chronic underselling of a country’s goods and services. The underselling is reflected in the fact that too little is invested compared to the amount of savings. For savings represent foregone consumption. If the private sector’s savings are higher that its investment, then the sum of investment and private consumption is too small to cover overall economic output. Problems for the economy can only be avoided if the public sector or foreign investors can absorb the savings overhang; in other words if they can compensate for the demand deficit. There is a heated debate over whether the world or Europe is currently in a state of secular stagnation.
