According to the authors the traditional laws of economics are still very much applicable to the tech businesses. To drive home their point, they cite similarities between the evolution of railroads, telephone and tech industries. Essentially the authors try to convey that traditional concepts like economies of scale and network effects are hardly unique to information economy, and fundamental principles of economics are relevant in an information economy too. In fact many information goods businesses have huge fixed costs in such as high R&D, and infrastructure costs in the case of telecommunications systems. Information is costly to produce but inexpensive to reproduce because some tech businesses have high fixed cost and low marginal costs. If a company lays fiber optic cable, buys switches and puts on a telecommunications system which are all fixed costs, after that it costs next to nothing for signals to be sent. One of the properties peculiar to information technology businesses is that they are subject to large increasing returns to scale on both the supply and demand side. Market outcomes in these markets tend to be concentrated and require standardization.

Traditional manufacturing industries had supply side economies of scale but often it ran into natural limits on the supply side, whereas a business like Microsoft not only has supply side economies of scale but it maintains absolute dominance is because of the demand side economies of scale. Microsoft’s customers value its operating systems because they are widely used and are the de facto industry standard. Unlike the supply side economies of scale, demand side economies of scale don’t dissipate when the market gets large enough. In fact it becomes a winner-take-all market. For investors willing to evolve and learn more about the economics of tech business this is a must read book.
