This paper introduces a new cost dataset for a commercial aircraft firm and uses this data to analyze the dynamics of learning in commercial aircraft production. This dataset is found to be inconsistent with the simple learning hypothesis, and particularly the prediction that a firm's unit cost...

This paper deals with processes that require several complementary inputs subject to improvements in quality. If after a quality upgrade one of these inputs requires a period of learning before it can be used effectively, then in general it will pay to purchase the inputs at different dates --...

We study an ambiguity-averse agent with uncertainty about income dynamics who chooses what aspects of the income process to learn about. The agent chooses to learn most about income dynamics at the very lowest frequencies, which have the greatest effect on utility. Deviations of consumption from...

One of the productive activities engaging the work force is reorganizing. When factors of production are better matched, productivity is higher. The probabilistic matching model of Diamond, Mortensen, and others provides a way to make the idea of reorganization precise. Because the flow of...

Some previous analyses have suggested that the smoothing of tax rates over time would be a desirable guide for public debt management. One implication of this viewpoint is that future changes in tax rates would be unpredictable based on current information. This proposition is tested by...

Complementing existing work on firm organizational structure and productivity, this paper examines the impact of organizational change on workers. We find evidence that employers do appear to compensate at least some of their workers for engaging in high performance workplace practices. We also...

There is increasing empirical evidence that creative destruction, driven by experimentation and the adoption of new products and processes when investment is sunk, is a core mechanism of development. Obstacles to this process are likely to be obstacles to the progress in standards of living....

There are significant differences in the dynamics of employment over the business cycle between young and old manufacturing plants. Young plants are more sensitive to aggregate disturbances, and they respond to them along different margins. We interpret these differences as reflecting greater...
