Economics is more than just a way to see patterns or to unravel puzzling anomalies. Its fundamental concern is with the material standard of living of society as a whole and how that is affected by particular decisions made by individuals and institutions. One of the ways of doing this is to look at economic policies and economic systems in terms of the incentives they create, rather than simply the goals they pursue. This means that consequences matter more than intentions--and not just the immediate consequences, but also the longer run repercussions of decisions, policies, and institutions.
