The case study discusses the impact of regulatory changes on Zara, a fashion retailer that expanded its operations to Australia. The removal of multiple layers of taxation and fixing GST at a revenue-neutral level reduced the tax burden on consumers, leading to an increase in sales and reaching targets in Australia. However, another regulatory change, the signing of a safety accord among apparel manufacturers by the world human rights organization, had a negative impact on Zara's business as some local Australian players refused to comply with the accord. This led to a decline in sales for several years, requiring Zara to invest heavily in promotional campaigns and brand-building exercises to regain its market share. The case highlights the importance of being agile and adaptable to regulatory changes that can have both positive and negative impacts on a business.
