Note that in the case of repeated roots of the denominator, a pole of multiple order contributes only a single residue. To evaluate F(s)ds by integrating around a closed contour enclosing the entire left half plane, note that if F()0 faster than-for large s, the integral along the curved part of the contour is zero

Economic growth‖ Is there some action a government of India could take that would lead the Indian economy to grow like Indonesia's or Egypt's? If so, what, exactly? If not, what is it about the \nature of India that makes it so? The conse- quences for human welfare involved in questions like these are simply stag- gering: Once one starts to think about them, it is hard to think about Robert E. Lucas, Jr

In late 1990, executives, engineers, and financial advisors working for Amoco Corporation and Apache Corporation began serious discussions about the sale to Apache of MW Petroleum Corporation, a wholly-owned subsidiary of Amoco Production Company. Amoco had transferred to MW certain of its own assets that it regarded as non-strategic. MW,s size, location, and operations were all very attractive to Apache, which had grown nearly 30% per year since the mid-1980s
