The module Principles of Economic Analysis I introduces students to basic concepts of Economics. Economics is a social science that studies the ways in which people interact with each other and make decisions in a world with limited resources. The aim of the course is to provide you with the basic tools "to think like an economist", that is, to be able to use the basic economic principles to ask and answer questions about how the world works or what the consequences of economic policies are.  The module will cover topics such as how individuals or businesses make decisions about the demand for or supply of a particular product, how we can assess market efficiency, and how we can assess the costs and benefits of government intervention in the market. The module is an introduction to microeconomics and covers, among others, topics such as supply and demand, consumer theory, the concept of elasticity and producer theory.
