We study the mobile phone-based money transfer system in Kenya. Based on aggregate data, we estimate that the velocity with which units of e-money are transferred among users is approximately four times per month, and that the average number of transfers undergone by a unit of e-money between...

In 2010, the number of consumer payments increased nearly 9 percent from 2009 as economic activity began to rebound from the financial crisis and recession. Cash payments by consumers, which had increased sharply in 2009, did not fall back but rather grew another 3 percent in 2010. However, the...

The Reserve Bank of Australia's third Survey of Consumers' Use of Payment Methods was conducted in November 2013. The survey used a diary and end-of-survey questionnaire to collect data on the use of cash, cards and a range of other payment methods, both at the point of sale and via remote...

In 2012, the number of consumer payments did not change significantly from 2010 as the economy settled into steady expansion following the financial crisis and recession. After increasing by 28 percent from 2008 to 2010, cash payments by consumers fell back by 10 percent from 2010 to 2012, while...

This paper considers the interaction between the microeconomic decisions facing households and the macroeconomic environment in a setting where households have 'real-world' mortgage contracts. In particular, we consider the possible consequences of the important changes in the framework for...

We examine the effects of presentation and information on the take-up of financial subsidies for retirement saving in a large randomized experiment carried out with H&R Block. The subsidies raise take-up and contributions with larger effects when the subsidy is characterized as a matching...

Experimental subjects allocate $10,000 across four S&P 500 index funds. Subject rewards depend on the chosen portfolio's subsequent return. Because the investments are not actually intermediated by the fund companies, portfolio returns are unbundled from non-portfolio services. The optimal...

Retirees confront the difficult problem of how to manage their money in retirement so as to not outlive their funds while continuing to invest in capital markets. We posit a dynamic utility maximizer who makes both asset location and allocation decisions when managing her retirement financial...

We examine the effects of collateralized borrowing in a realistically parameterized life-cycle portfolio choice problem. We provide basic intuition in a two-period model and then solve a multi-period model computationally. Our analysis provides insights into life-cycle portfolio choice relevant...

We show how standard consumer and producer theory can be used to estimate welfare in insurance markets with selection. The key observation is that the same price variation needed to identify the demand curve also identifies how costs vary as market participants endogenously respond to price....
