TECHNOLOGY: The sum total of knowledge and information that society has acquired concerning the use of resources to produce goods and services. This technology often takes the form of scientific knowledge (the best combination of chemicals to make a long-lasting floor wax), but can also be plain old common sense (irrigate during a drought, not during a flood). Whether scientific or not, technology affects the technical efficiency with which resources are combined in production. An improvement in technology is thus an increase in the technical efficiency of production--more output with given inputs or fewer inputs for a given output. Technology is often embodied in capital goods. Bigger, better, faster, and less expensive computers are the result of advances in silicon chip technology. However, technology is also embodied in labor as human capital.

ASYMMETRIC INFORMATION Information is not equally available to everyone. Asymmetric information results because efficient information search inevitably stops short of compete information. Some people obtain more benefits from information than others, are willing to incur higher search costs, and thus end up knowing more. Or they incur lower information search costs and have easier access to the information. In a market, sellers tend to have more information about the good than buyers. Asymmetric information gives rise to adverse selection, moral hazard, and the principal-agent problem. These problems can be lessened through signalling and screening.
