Imitation, Entrepreneurship, and Long-Run Growth
构建了一个内生创业活动驱动经济增长的模型，强调模仿而非直接知识生产是增长的关键，并分析了创业活动的外部效应。
Despite the widespread belief that entrepreneurship is a key factor in economic development, there have been few attempts to develop formal models to analyze the phenomenon. This paper presents a model in which endogenous entrepreneurial activity is a key determinant of economic growth. The theory also differs from standard models in that growth is driven by the imitative activities of entrepreneurs. Previous theories have focused on the direct production of knowledge, underemphasizing the importance of imitation in the growth process. The paper also examines external effects arising from these entrepreneurial activities--effects distinct from those studied by Paul Romer. Copyright 1989 by University of Chicago Press.
