Фирма, находясь в условиях совершенной конкуренции, имеет функцию общих затрат ТС=140+10Q+40Q2. При каком выпуске прибыль фирмы будет максимальна, если цена установилась на уровне 250 ден. ед.? Определить размер прибыли фирмы.
MR (прибыль)=TR(общая выручка)-TC(общие издержки)=P*Q-TC=P*Q-140-10Q-40Q^2=250Q-140-10Q-40Q^2=-140+240Q-40Q^2→max
Q=3 – точка максимума (определяется при подстановке в производную значений меньших и больших трех, при прохождение с + на – получается точка максимума)
Ответ: 220 д.е.

The Critical Path: Inventing an Automobile and Reinventing a Corporation The story of how Chrysler's minivan team created an automobile that captured the 1995 Motor Trend Car of the Year and other major awards - and reinvented a perilously entrenched corporation in the process - is as dramatic and inspiring a story as any in business today. Brock Yates, one of the most respected writers in the auto world, was given unprecedented access to Chrysler - every planning session, presentation, budget review, test drive, assembly line start-up, and marketing launch. The result is a book that unveils the mysteries of modern car-making, revealing how cars are shaped through countless interlinked decisions ranging from size and power to door configurations, color selections, and innumerable other interconnected details. It also capturesthe complex process by which the thousands of separate pieces that make up a car are designed, tested, manufactured, and marshaled into place at the exact moment they are needed. For any reader who cares about cars, this is the most...

Shipyard in Maine: Percy & Small and the Great Schooners Towards the end of the nineteenth century, a new firm was established in Bath, Maine, at a time when established yards in the City of Ships were turning to steel construction. Percy & Small would set unrivaled records for wooden shipbuilding and ship management, launching 22 giant five- and six-masted schooners (along with 16 four-masters) in two decades. Not just builders, Percy & Small also demonstrated an unusual knack for making money as managing owners of a large fleet of schooners, and the stories of their ships are told in these pages in wonderful detail, from the wooing of potential shareholders and the elaborate launching festivities (with one schooner stuck on the ways) to deeply laden coal schooners struggling to stay off the lee shore, daring captains navigating treacherous shoals, and the perils of collisions, dismastings, fires, and enemy submarines. At sea in a storm, a giant six-master heavy with coal needed great strength to survive. Percy & Small developed...
Diversification, Refocusing, and Economic Performance During the 1980s a dramatic change in the evolution of the modern corporation took place. The phenomenon, which has been labelled "refocusing," "de-diversifying," "de-conglomerating," or simply "getting back to basics," has changed the terrain of American business. Diversification, Refocusing, and Economic Performance empirically examines the causes and consequences of this phenomenon from a corporate strategy perspective, uncovering the full scope and effects of corporate refocusing, its strategic logic, and the resultant managerial implications. Two key findings are that every firm has its own limit for diversification, beyond which profits will decline, and that there are certain similarities among those companies who choose to refocus. Starting right after the Second World War, many companies diversified widely, primarily in areas unrelated to their core businesses. In the 1980s, however, as corporate acquisitions and hostile takeovers ran rampant, this trend...

A CEO is celebrated on the covers of BusinessWeek, Forbes, and Fortune. Soon after, the company is in the midst of a disastrous merger or some other fiasco. What goes wrong in these cases?
