We provide a Keynesian growth theory in which pessimistic expectations can lead to very persistent, or even permanent, slumps characterized by unemployment and weak growth. We refer to these episodes as stagnation traps, because they consist in the joint occurrence of a liquidity and a growth trap. In a stagnation trap, the central bank is unable to restore full employment because weak growth depresses aggregate demand and pushes the interest rate against the zero lower bound, while growth is weak because low aggregate demand results in low profits, limiting firms' investment in innovation. Policies aiming at restoring growth can successfully lead the economy out of a stagnation trap, thus rationalizing the notion of job creating growth.

This paper describes the stylized facts characterizing periods of exceptionally large capital inflows in a sample of 70 middle-and high-income countries over the last 35 years. We identify 155 episodes of large capital inflows and find that these events are typically accompanied by an economic boom and followed by a slump. Moreover, during episodes of large capital inflows capital and labor shift out of the manufacturing sector, especially if the inflows begin during a period of low international interest rates. However, accumulating reserves during the period in which capital inflows are unusually large appears to limit the extent of labor reallocation. Larger credit booms and capital inflows during the episodes we identify increase the probability of a sudden stop occurring during or immediately after the episode. In addition, the severity of the post-inflows recession is significantly related to the extent of labor reallocation during the boom, with a stronger shift of labor out of manufacturing during the inflows episode associated with a sharper contraction in the aftermath of the episode.
