Luxuries, Necessities, and the Allocation of Time
Households enjoy utility from activities that require a combination of time and goods. We classify activities into two types: luxuries and necessities. Luxuries (necessities) are activities for which time and expenditure shares rise (decline) with income. We develop and estimate a model with nonhomothetic preferences and find that time and goods are substitutable in producing activities. Activities are also substitutable among themselves. Hence, wage and price changes cause large reallocations of time and expenditures across activities. This effect is quantitatively important for welfare ...

Bundling Time and Goods: Implications for Hours Dispersion
We document the large dispersion in hours worked in the cross-section. We account for this fact using a model in which households combine market inputs and time to produce a set of nonmarket activities. To estimate the model, we create a novel data set that pairs market expenditures and time use at the activity level using data from the Consumer Expenditure Survey and the American Time Use Survey, respectively. The estimated model can account for a large fraction of the dispersion of hours worked in the data. The substitutability between market inputs and time within an activity and across a ...

Growing Electric Vehicle Adoption: Implications for Infrastructure Maintenance and the Tax Burden on Families of Different Funding Policies
This paper examines the distribution of the gasoline tax burden in the presence of increased electric vehicle adoption. Automobile manufacturers and even some states have ambitious goals to phase out gas-powered cars. However, in spite of these plans, the primary source of automobile infrastructure funding in the United States continues to be gasoline taxes. Less demand for gasoline threatens this source of revenue for maintaining roads and further shifts the burden of the tax toward consumers who can’t afford the still relatively expensive electric vehicles. The analysis here illustrates ...

Scarcity and Intertemporal Choice
Scarcity is a ubiquitous experience, and existing evidence largely suggests that people become more myopic when they feel their resources are scarce. Importantly, evidence for this proposition comes primarily from contexts in which scarcity threatens needs that require resources imminently. The current work examines instances in which scarcity threatens needs along a broader time horizon. Archival data from the Federal Reserve Bank of Philadelphia’s Consumer Finance Institute and five pre-registered studies (N = 7,728) show that the time horizon of threatened needs is an important ...

Why Does Consumption Fluctuate in Old Age and How Should the Government Insure it?
In old age, consumption can fluctuate because of shocks to available resources and because health shocks affect utility from consumption. We find that even temporary drops in income and health are associated with drops in consumption and most of the effect of temporary drops in health on consumption stems from the reduction in the marginal utility from consumption that they generate. More precisely, after a health shock, richer households adjust their consumption of luxury goods because their utility of consuming them changes. Poorer households, instead, adjust both their necessary and luxury ...

Optimal Monetary Policy Under Bounded Rationality
Optimal monetary policy under discretion, commitment, and optimal simple rules regimes is analyzed through a behavioral New Keynesian model. Flexible price level targeting dominates under discretion; flexible inflation targeting dominates under commitment; and strict price level targeting dominates when using optimal simple rules. Stabilizing properties and bounded rationality-independence generally affect the regime's optimality. The policymaker's knowledge of an agent's myopia is decisive, whereas bounded rationality is not necessarily associated with decreased welfare. Several forms of ...

Welfare Evaluation in a Heterogeneous Agent Model: How Representative is the CES Representative Consumer?
The present paper investigates the impact of asymmetric price changes on welfare in a model with heterogeneous consumers. I consider consumer heterogeneity a la Anderson et al. (1992). The standard welfare equivalence between the CES representative consumer and the discrete choice model breaks down in presence of asymmetric price changes. In fact, asymmetric variation in prices produce differential gains among heterogeneous consumers. I show that there exists no feasible Kaldor-Hicks income transfer such that the gains are equally redistributed. Intuitively, in presence of decreasing marginal ...

Market Power and Asset Contractibility in Dynamic Insurance Contracts
The authors study the roles of asset contractibility, market power, and rate of return differentials in dynamic insurance when the contracting parties have limited commitment. They define, characterize, and compute Markov-perfect risk-sharing contracts with bargaining. These contracts significantly improve consumption smoothing and welfare relative to self-insurance through savings. Incorporating savings decisions into the contract (asset contractibility) implies sizable gains for both the insurers and the insured. The size and distribution of these gains depend critically on the insurers? ...

Portfolio choice with house value misperception
Households systematically overvalue or undervalue their houses. We compute house value misperception as the difference between self-reported and market house values. Misperception is sizable, countercyclical, and persistent. We find that a 1 percent increase in house overvaluation results, on average, in a 4.56 percent decrease in the share of risky stock holdings for those households that participate in the stock market. We then build a rational inattention model in which households make decisions based on their perceived level of housing wealth. Numerical simulations generate the effects of ...
