7.1 INTRODUCTION
In this unit we study the economics of information. This area
of study is becoming increasingly important in economics - and
deservingly so. The unit begins by examining the economics of
search: search costs, the process of searching for the lowest price
of the product, and the information content of advertising. The unit
goes on to discussing asymmetric information
and the market for
lemons (i.e. defective products), the insurance market and adverse
selection, market signalling, moral hazard,
the principal-agent
problem, and the efficiency wage theory.
