The COVID-19 pandemic has caused large changes in consumer spending, including how people make their payments. We use data from a nationally representative survey of U.S. consumers collected before COVID in 2018 and 2019 and during COVID in 2020 to analyze changes in consumer payment behavior...

We construct an index theorem for smooth infinite economies that shows that generically the number of equilibria is odd. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria.

We study global properties of the equilibrium set of economies with a continuous consumption space. This framework is important in intertemporal allocation problems (continuous or infinite time), financial markets with uncertainty (continuous states of nature) and commodity differentiation. We...

The main contribution of this paper is to place smooth infinite economies in the setting of the equilibrium manifold and the natural projection map à la Balasko. We show that smooth infinite economies have an equilibrium set that has the structure of a Banach manifold and that the natural...

We propose that individuals consider future versions of themselves to truly be separate persons, not simply as a convenient modeling device but in terms of actual brain systems and decision]making processes. Intertemporal choices are thus quite literally strategic interactions between multiple...

We prove that the change in welfare of a representative consumer is summarized by the current and expected future values of the standard Solow productivity residual. The equivalence holds if the representative household maximizes utility while taking prices parametrically. This result justifies...

This paper introduces the concept of categorizing the amount and speed of a discounting procedure in order to generate well-characterized families of procedures for use in social project evaluation. Exponential discounting isolates the concepts of amount and speed into a single parameter that...

In aggregate, state appropriations are the largest revenue source for public higher education in the United States. However, these appropriations have significantly declined over past decades, drawing serious concerns about the potential negative impact on schools and students. This paper...

This paper evaluates the success of National Literacy Program (PNA) “Yo Si Puedo”. First, we evaluate whether the implementation of PNA is associated with a change in the level and trend of illiteracy, and if such changes were sufficient to reduce the incidence of illiteracy below 4% - a...

This paper assesses the impact of Bolivia’s school subsidy program, Bono Juancito Pinto (BJP), on school attendance. BJP is a relatively small cash transfer (less than 30 dollars per child per year) given conditional on being enrolled into a public school and on regular school attendance....
