Question:In Porter’s five forces model, which of the following would not constitute a ‘barrier to entry’?
  A.Scale economies available to existing competitors
  B.High capital investment requirements
  C.Low switching costs in the market
   Answer:C
         Rationale: Low switching costs means that it will be easy for customers to change from existing suppliers to a new supplier: this would facilitate entry to the market. The other options should clearly pose difficulties to a new entrant: not yet big enough to benefit from economies of scale (against competitors who are); high start-up costs; high degree of recognition of and loyalty to existing brands.
