Effects of Capacity Acquisition Policcies

Each year more than 400,000 new enterprises are formed, of which only 41% survive beyond their fifth birthday. Of the failures, 52% are due entirely to managerial incompetence and another 40% to lack of experience. Clearly the growth period presents company management a most difficult managerial task. This book studies the interaction between a company's capacity-acquisition policy and the growth rate of its new product: it demonstrates how different policies of acquiring manufacturing capacity can either suppress or facilitate this growth rate.

A General Hypothesis and a Test Model of a Grassland

Natural ecosystems such as lakes, grasslands, and forests undergo succession from their early stages of development to maturity, when the community of plants and animals achieves a condition of equilibrium with its physical environment. Because ecosystems succeed in response to either natural or man-made disturbances, it is important to understand how successional behavior arises and how to control it to avoid permanent deterioration of systems indispensable for our survival.
