Is the deodorant market an oligopoly or monopolistic competition and why? According to some, supplier power and substitution power in the industry is very low. Are they correct? Please briefly explain/defend your position. Lastly, which of Porter's five forces (i.e, supplier power, buyer power, competitive rivalry, threat of substitution, threat of new entry) worries you the most if you are a CPG manufacturer considering entering the deodorant market? Thank you.
