n this paper I examine changes in self-employment that have occurred since the early 1980s in the United States. It is a companion paper to a recent equivalent paper that related to the UK. Data on random samples of approximately twenty million US workers are examined taken from the Basic...

Recent arguments that employment growth occurs disproportionately at small establishments are fundamentally misleading because they confuse regression to the mean with structural shifts in the size distribution of establishments and with an aging effect within cohorts. The net growth usually...

The extensive literature on knowledge management spans several fields, but there are remarkably few studies that address the basic question as to whether knowledge management practices improve organizational performance. I examine that question using a national probability sample of...

This paper shows that top management structures in large US firms radically changed since the mid-1980s. While the number of managers reporting directly to the CEO doubled, the growth was driven primarily by functional managers rather than general managers. Using panel data on senior management...

This paper investigates the divisional investment policies of diversified firms. We find that investment of the smallest division of diversified firms is significantly related to the cash flow of the other segments. We then show that the smallest division's investment is more sensitive to the...

In a simple model of capital budgeting in a diversified firm where headquarters has limited power, we show that funds are allocated towards the most inefficient divisions. The distortion is greater the more diverse are the investment opportunities of the firm's divisions. We test these...

Theories based on incomplete contracting suggest that small organizations may do better than large organizations in activities that require the processing of soft information. We explore this idea in the context of bank lending to small firms, an activity that is typically thought of as relying...

We examine a sample of over thirty thousand transactions by corporate and other venture organizations. Corporate venture investments in entrepreneurial firms appear to be at least as successful (using such measures as the probability of the portfolio firm going public) as those backed by...

What is the optimal form of firm organization during “bad times”? We present a model of delegation within the firm to show that the effect is ambiguous. The greater turbulence following macro shocks may benefit decentralized firms because the value of local information increases (the...

Hierarchies allow individuals to leverage their knowledge through others' time. This mechanism increases productivity and amplifies the impact of skill heterogeneity on earnings inequality. To quantify this effect, we analyze the earnings and organization of U.S. lawyers and use the equilibrium...
