内容摘要：This paper documents a negative relationship between households’ marginal propensity to consume (MPC) and the price stickiness of goods they purchase. Households with larger MPC consume goods whose prices are on average more flexible. This group of households experience higher inflation after an expansionary monetary policy shock. We embed this negative relationship into a tractable multi-sector Two-Agent New Keynesian (TANK) model, and show analytically that it dampens the potency of monetary policy. Quantitatively, the real effects of monetary policy are 15 percent less compared to a benchmark model with homogeneous consumption baskets. The optimal monetary policy differs qualitatively from what it would be in its TANK counterpart. Introducing heterogeneous consumption baskets leads to intrinsically inefficient flexible-price equilibrium, and generates a new type of sta- bilization v.s. redistribution tradeoff.
