Macroeconomic models often invoke consumption “habits” to explain the substantial persistence of aggregate consumption growth. But a large literature has found no evidence of habits in microeconomic datasets that measure the behavior of individual households. We show that the apparent...

The largest economic cost of the COVID-19 pandemic could arise from changes in behavior long after the immediate health crisis is resolved. A potential source of such a long-lived change is scarring of beliefs, a persistent change in the perceived probability of an extreme, negative shock in the...

Dynamically and statically optimal Pigouvian subsidies on durables will differ in a growing economy. For durables with positive externalities, such as sanitation, statically optimal subsidies will typically grow. However, in a dynamic game, governments can most cheaply induce optimal purchasing...

We estimate the degree of amp;apos;stickinessamp;apos; in aggregate consumption growth (sometimes interpreted as reflecting consumption habits) for thirteen advanced economies. We find that, after controlling for measurement error, consumption growth has a high degree of autocorrelation, with a...

We investigate the relationship between (a) official information on COVID-19 infection and death case counts; (b) beliefs about such case counts, at present and in the future; (c) beliefs about average infection chance—in principle, directly calculable from (b); and (d) self-reported...

Questionnaire surveys undertaken in 1988 and annually from 2003 through 2014 of recent homebuyers in each of four U.S. metropolitan areas shed light on their expectations and reasons for buying during the recent housing boom and subsequent collapse. They also provide insight into the reasons for...

How significant are individual differences in self-control? Do these differences impact wealth accumulation? From where do they derive? Our survey-based measure of self-control provides insights into all three questions: 1.There are individual differences in self-control not only of a...

The appropriateness of many high-cost loan regulations depends on whether demand is driven by financial conditions (“misfortunes”) or imperfect decisions (“mistakes”). Bank records from Iceland show borrowers are especially illiquid just before getting a loan, but that some spend the...

In recent years, numerous U.S. cities have enacted taxes on sweetened beverages, but there is relatively little evidence about the effects of these taxes on purchases and consumption. In this paper, we examine the effects of the beverage tax of 1.5 cents per ounce that was implemented in...

The intermittency of payment for many goods creates a disconnect between paying and consuming such that the marginal price is not always salient when consumption decisions are made. This paper derives optimal dynamic corrective taxes when there are externalities as well as internalities from...
