Recommended Prior Learning

None, previous study at levels 1-2 may help but is not essential. 

Commerce at level 3 NCEA will allow students to complete an in depth study of microeconomic concepts (Theory behind business, particularly Marketing)  This involves free market economics including a study of Supply and Demand including Elasticity, Allocative Efficiency, Marginal Analysis and Market Failure.  Specific topics of interest could include the elasticities of demand in the coffee industry, housing supply and house prices, supermarkets and abuse of market power,  The economics of waste, compulsory vaccination, sugar tax, environmental economics and inequality.  

Motivated students can continue with a more practical Business Studies course or complete both Business and Economics by taking part in the YES program and carrying out a business activity, including completing a marketing plan and a full business plan. 

Economics and Business are both approved subjects* for University Entrance and can lead to further study in Commerce, Politics, Arts, Law and many other fields or may just be taken for interest.
