Smoother labor incomes alleviate credit constraints by reducing workers' desire to borrow, and prospects of upward income mobility have smaller beneficial effects for currently poor workers when borrowing constraints are binding. These simple theoretical insights are consistent with the...

Over the last three decades, average income for the bottom half of the US distribution increased by 8% while their average saving rate decreased by eight percentage points. Over the same period the US experienced a substantial increase in inequality and a continuous decrease in the aggregate...

Feldstein [1985] posed the questions of what would be the optimal level of retirement benefit, and what would be the optimal mix between the pay-as-you-go system and the funded pension system under the assumption of an exogenous interest rate. We reconsider the problem with the addition of a...

Individuals frequently face intertemporal decisions. For the purposes of economic analysis, the preference parameters assumed to govern these decisions are generally considered to be stable economic primitives. However, evidence on the stability of time preferences is notably lacking. In a large...

Standard economic analysis assumes that people make choices that maximize their utility. Yet both popular discourse and other fields assume that people sometimes fail to make optimal choices and thus adversely affect their own happiness. Most social sciences thus frequently describe some...

We study consumption and welfare inequality by analyzing how households allocate resources—market expenditures and the value of time—to the production of activities. The share of resources allocated to an activity rises or falls with wages, classifying them into luxuries or necessities,...
