In this paper, we examine the importance of year, industry, corporate‐parent, and business‐specific effects on the profitability of U.S. public corporations within specific 4‐digit SIC categories. Our results indicate that year, industry, corporate‐parent, and business‐specific effects account for 2 percent, 19 percent, 4 percent, and 32 percent, respectively, of the aggregate variance in profitability. We also find that the importance of the effects differs substantially across broad economic sectors. Industry effects account for a smaller portion of profit variance in manufacturing but a larger portion in lodging/entertainment, services, wholesale/retail trade, and transportation. Across all sectors we find a negative covariance between corporate‐parent and industry effects. A detailed analysis suggests that industry, corporate‐parent, and business‐specific effects are related in complex ways. © 1997 by John Wiley & Sons, Ltd.

Inclusive innovation, which we define as innovation that benefits the disenfranchised, is a process as well as a performance outcome. Consideration of inclusive innovation points to inequalities that may arise in the development and commercialization of innovations, and also acknowledges the inequalities that may occur as a result of value creation and capture. We outline opportunities for the development of theory and empirical research around this construct in the fields of entrepreneurship, strategy, and marketing. We aim for a synthesis in views of inclusive innovation and call for future research that deals directly with value creation and the distributional consequences of innovation.

This paper explores innovation, experimentation, and creativity in the public domain and in the public interest. Researchers in various disciplines have studied public entrepreneurship, but there is little work in management and economics on the nature, incentives, constraints, and boundaries of entrepreneurship directed to public ends. We identify a framework for analyzing public entrepreneurship and its relationship to private entrepreneurial behavior. We submit that public and private entrepreneurship share essential features but differ critically regarding the definition and measurement of objectives, the nature of the selection environment, and the opportunities for rent seeking. We describe four levels of analysis for studying public entrepreneurship, provide examples, and suggest new research directions.

In this paper, we analyze the variance of accounting profitability among a broad cross-section of forms in the American economy from 1981 to 1994. The purpose of the analysis is to identify the importance of year, industry, corporate-parent, and business-specific effects on accounting profitability among operating businesses across sectors. The findings indicate that industry and corporate-parent effects are important and related to one another. As expected, business-specific effects, which arise from competitive positioning and other factors, have a large influence on performance. The analysis reconciles the results of previous studies by exploring differences in method and data. We also identify the broad contributions and limitations of the research, and suggest avenues for further study. New approaches are necessary to generate significant insights about the relationships between industry, corporate-parent, and business influences on firm profitability.performance, sustainability, industry structure, corporate strategy
