This paper develops a model based on Schumpeter's process of creative destruction. It departs from existing models of endogenous growth in emphasizing obsolescence of old technologies induced by the accumulation of knowledge and the resulting process or industrial innovations. This has both positive and normative implications for growth. In positive terms, the prospect of a high level of research in the future can deter research today by threatening the fruits of that research with rapid obsolescence. In normative terms, obsolescence creates a negative externality from innovations, and hence a tendency for laissez-faire economies to generate too many innovations, i.e too much growth. This "business-stealing" effect is partly compensated by the fact that innovations tend to be too small under laissez-faire. The model possesses a unique balanced growth equilibrium in which the log of GNP follows a random walk with drift. The size of the drift is the average growth rate of the economy and it is endogenous to the model ; in particular it depends on the size and likelihood of innovations resulting from research and also on the degree of market power available to an innovator.

From one of the world’s leading economists and his coauthors, a cutting-edge analysis of what drives economic growth and a blueprint for prosperity under capitalism. Crisis seems to follow crisis. Inequality is rising, growth is stagnant, the environment is suffering, and the COVID-19 pandemic has exposed every crack in the system. We hear more and more calls for radical change, even the overthrow of capitalism. But the answer to our problems is not revolution. The answer is to create a better capitalism by understanding and harnessing the power of creative destruction—innovation that disrupts, but that over the past two hundred years has also lifted societies to previously unimagined prosperity. To explain, Philippe Aghion, Céline Antonin, and Simon Bunel draw on cutting-edge theory and evidence to examine today’s most fundamental economic questions, including the roots of growth and inequality, competition and globalization, the determinants of health and happiness, technological revolutions, secular stagnation, middle-income traps, climate change, and how to recover from economic shocks. They show that we owe our modern standard of living to innovations enabled by free-market capitalism. But we also need state intervention with the appropriate checks and balances to simultaneously foster ongoing economic creativity, manage the social disruption that innovation leaves in its wake, and ensure that yesterday’s superstar innovators don’t pull the ladder up after them to thwart tomorrow’s. A powerful and ambitious reappraisal of the foundations of economic success and a blueprint for change, The Power of Creative Destruction shows that a fair and prosperous future is ultimately ours to make.

Leading social scientists explore pressing issues--monopoly and inequality, growth and innovation, climate change and fraying social safety nets--through the lens of creative destruction. Far more than a theory of capitalist dynamics, creative destruction proves an important idea for illuminating a wide range of social and political challenges.

Turning conventional wisdom on its head, a Senior Partner and an Innovation Specialist from McKinsey & Company debunk the myth that high-octane, built-to-last companies can continue to excel year after year and reveal the dynamic strategies of discontinuity and creative destruction these corporations must adopt in order to maintain excellence and remain competitive. In striking contrast to such bibles of business literature as In Search of Excellence and Built to Last, Richard N. Foster and Sarah Kaplan draw on research they conducted at McKinsey & Company of more than one thousand corporations in fifteen industries over a thirty-six-year period. The industries they examined included old-economy industries such as pulp and paper and chemicals, and new-economy industries like semiconductors and software. Using this enormous fact base, Foster and Kaplan show that even the best-run and most widely admired companies included in their sample are unable to sustain their market-beating levels of performance for more than ten to fifteen years. Foster and Kaplan's long-term studies of corporate birth, survival, and death in America show that the corporate equivalent of El Dorado, the golden company that continually outperforms the market, has never existed. It is a myth. Corporations operate with management philosophies based on the assumption of continuity; as a result, in the long term, they cannot change or create value at the pace and scale of the markets. Their control processes, the very processes that enable them to survive over the long haul, deaden them to the vital and constant need for change. Proposing a radical new business paradigm, Foster and Kaplan argue that redesigning the corporation to change at the pace and scale of the capital markets rather than merely operate well will require more than simple adjustments. They explain how companies like Johnson and Johnson , Enron, Corning, and GE are overcoming cultural "lock-in" by transforming rather than incrementally improving their companies. They are doing this by creating new businesses, selling off or closing down businesses or divisions whose growth is slowing down, as well as abandoning outdated, ingrown structures and rules and adopting new decision-making processes, control systems, and mental models. Corporations, they argue, must learn to be as dynamic and responsive as the market itself if they are to sustain superior returns and thrive over the long term. In a book that is sure to shake the business world to its foundations, Creative Destruction, like Re-Engineering the Corporation before it, offers a new paradigm that will change the way we think about business.
