We document two facts. First, during the Great Recession, consumers traded down in the quality of the goods and services they consumed. Second, the production of low-quality goods is less labor intensive than that of high-quality goods. When households traded down, labor demand fell, increasing...

We study a model in which the effects of taxation on growth are highly non-linear. Marginal increases in tax rates have a small growth impact when tax rates are low or moderate. When tax rates are high, further tax hikes have a large, negative impact on growth performance. We argue that this...

We propose a model consistent with two observations. First, the tax rates adopted by different countries are generally uncorrelated with their growth performance. Second, countries that drastically reduce private incentives to invest, severely hurt their growth performance. In our model, the...

Recent empirical work suggests that small price changes are relatively common. This evidence has been used to criticize classic menu-cost models. In this paper, we use scanner data from a national supermarket chain and micro data from the Consumer Price Index to reassess the importance of small...

Aggregate and sectoral comovement are central features of business cycle data. Therefore, the ability to generate comovement is a natural litmus test for macroeconomic models. But it is a test that most existing models fail. In this paper we propose a unified model that generates both aggregate...

We explore the business cycle implications of expectation shocks and of two well-known psychological biases, optimism and overconfidence. The expectations of optimistic agents are biased toward good outcomes, while overconfident agents overestimate the precision of the signals that they receive....

We study the impact on the skill premium of increases in the quality of goods consumed by households ("trading up"). Our empirical work shows that high- quality goods are more intensive in skilled labor than low-quality goods and that household spending on high-quality goods rises with income....
