The President's Commission to Strengthen Social Security proposed three reform plans. Two, analyzed here, restore actuarial balance in the absence of individual accounts. One achieves this balance solely through benefit reductions. The other uses new dedicated revenue to cover one-third of the...

General Motors was once regarded as one of the best managed and most successful firms in the world, but between 1980 and 2009 its share of the US market fell from 62.6 to 19.8 percent, and in 2009 the firm went bankrupt.

Economists have often argued that "pay for performance" is the optimal compensation scheme. However, use of the simplest form of pay for performance, the piece rate, has been in decline in manufacturing in recent decades. We show both theoretically and empirically that these changes are due to...

Over the last 20 years, the success of Japanese manufacturing firms has brought renewed attention to the importance of cost reduction on existing products as a source of productivity growth. This paper uses survey data and field interviews from the auto supply industry to explore the...

Using an original data source, this paper investigates the circumstances under which firms adopt computer numerical control (CNC), an important type of flexible automation which can significantly increase productivity, product variety and quality. The paper shows that arms'-length...

While the Sharpe ratio is still the dominant measure for ranking risky assets, a substantial effort has been made over the past three decades to find a way to account for non-Normally distributed risks. This paper derives a generalized ranking measure which, under a regularity condition,...
