The standard approach to modelling consumption/saving problems is to assume that the decisionmaker is solving a dynamic stochastic optimization problem However under realistic descriptions of utility and uncertainty the optimal consumption/saving decision is so difficult that only recently...

This paper introduces a method for solving numerical dynamic stochastic optimization problems that avoids rootfinding operations. The idea is applicable to many microeconomic and macroeconomic problems, including life cycle, buffer-stock, and stochastic growth problems. Software is provided.

In the United Kingdom, money demand deviates from the convex relationship suggested by monetary theory. Limited commitment of borrowers via banks can explain this observation. Our finding is based on a microfounded monetary model, where a money market provides insurance against idiosyncratic...

Cash users withdraw money from automated teller machines (ATMs) to finance cash payments. However, most ATMs in the United States dispense only multiples of $20 bills. The paper first constructs a consumer's optimization model showing how the precise denomination of dollar bills available from...

The emergence of cashless stores has led several cities and states to ban such stores. This paper investigates this issue by characterizing consumers who pay cash for in-person purchases and consumers who do not have credit or debit cards. I construct a model of consumer payment choice and use...

Overwhelming evidence from the cognitive sciences shows that, in simple discrimination tasks (determining what is louder, longer, brighter, or even which number is larger) humans make more mistakes and decide more slowly when the stimuli are closer along the relevant scale. We investigate to...

This paper has two objectives. First it provides a correlation between internal and external barriers to energy efficiency and consumer behaviour related to two domains. It evaluates behaviour related to energy curtailment, which represents routine, repetitive effort to decrease consumption on a...

The paper investigates the degree to which buyers choose to diversify their use of payment methods for in-person purchases. Some buyers use only one payment instrument. Others combine the use of mostly cash, credit, debit cards, and a few paper checks and prepaid cards. To each survey...

Low-income consumers are not only constrained with spending, but also with the type and variety of payment methods available to them. Using a representative sample of the U.S. adult population, this paper analyzes the low possession (adoption) of credit and debit cards among lowincome consumers...

Players may categorize the strategies available to them. In many games there are different ways to categorize one's strategies (different frames) and which ones players use has implications for the outcomes realized. This paper proposes a model of agents who learn which frames to use through...
