What Individual Investors Say Matters to Them

Big Data and High-Performance Computing
Deepening the Study of Financial Economics

Over the last decade, researchers have gained access to datasets on transactions in financial markets that make it possible to study market mechanisms in more detail, and at higher resolution, than ever before. Because these data sets are often far larger than those traditionally used by financial economists, analyzing them requires new strategies for data management and analysis. The advent of high-performance computing facilitates research using these datasets. With support from the National Center for Supercomputing Applications, the NBER convened a meeting in July at which researchers discussed potential uses of the new data resources, loosely called "big data," and experts on supercomputing provided an overview of available tools and resources.

Also in this issue of the monthly Digest are summaries of research analyzing the lingering effects of the crack crisis, calculating the influence of probability weighting on household investment decisions, comparing the competitiveness of markets in the United States and the EU, and measuring the growth in Chinese research, and examining the effect of pride in national sports teams on ethnic tensions in African countries.

The Lifetime Medical Spending of Retirees
Evolves In Counterintuitive Ways as They Age

Properly estimating a household's lifetime medical costs is an essential element of financial retirement planning. A study summarized in the current edition of the NBER's Bulletin on Aging and Health documents the medical history of retirees over a 20 year period and finds that in many cases total future medical expenses actually rise with age until around age 90, even though the subjects have less time to live. Also in this edition of the Bulletin on Aging and Health: A historical exploration of the male-female life expectancy gap, and a glimpse into the cutting edge application of machine learning in the field of healthcare.
