Price Volatility, Competitiveness, And Innovation In The South African Wine Industry
The South African wine industry is the eighth largest producer of wine in the world. Despite its progress since the 1990s, the industry has come under increased competition from other wine producers. The wine industry grew rapidly from 1994 until 2005 when it started to face major challenges that led to only a quarter of wine farmers producing at financially sustainable levels, reductions in the number of grape farmers and the area of vineyard under cultivation, and job cuts, low pay, and low prices. The most immediate constraints to the competitiveness of the wine industry are global competition, inadequate innovation, and volatile input costs of production. Therefore, this thesis contributes to the debate on these issues by (i) examining South Africa's wine competitiveness against other Southern Hemisphere New World (SHNW) producers; and (ii) investigating wine consumers' perceptions of and willingness to pay for product innovation by the South African wine industry; and (iii) investigating the impact of energy price volatility on South African wine prices. The main research questions/contributions are addressed in Chapters 3, 4, 5 and 6 as follows: Chapter 3 investigates the competitiveness of South African wines against rivals in the SHNW, and the determinants of their performance in the global wine market. The aim is to identify priority areas to focus on to enhance South Africa's competitiveness and sustain the industry. Global competition, especially among the SHNW producers, has been cited as one of the causes of the poor performance by the South African wine industry (Esterhuizen and Van Rooyen, 2006; Van Rooyen et al., 2011; Van Rooyen and Boonzaaier, 2018). The export market is critical for South African wines considering that half of its annual production is sold abroad (SAWIS, 2020). Also that exports attract higher earnings for the industry. Therefore, comparing the degree of South African wine competitiveness with other SHNW producers and investigating factors influencing specialisation will help identify priority areas to focus on to enhance South Africa's competitiveness and sustain the industry. The 1990 to 2018 panel data from Global Wine Markets is used for the analysis. Trade specialisation and their determinants are determined through (i) the computation of the Revealed Comparative Advantage, (ii) estimation of the Galtonian regression model and (iii) estimation of the panel regression model. The findings reveal that all countries migrated to higher price points with variable degrees of success. As a result, South African wines were relatively less competitive than their rivals. The study reveals the relative position of the South African wine industry and draws inferences on priority areas for enhancing competitiveness. Chapter 4 investigates wine consumers' perceptions of and willingness to pay for product innovation by the South African wine industry. The aim is to elicit information on whether consumers are ready to pay for wines made with natural preservatives (Rooibos & Honeybush), organic production, and a higher quality score. Determining whether consumers choose such wines is crucial as it would reveal whether wine players can exploit this source of avenue to save the struggling industry. It contributes to knowledge by being the first study to estimate the premium price for not having added SO2 in wine by substituting the conventional wine preservative with Rooibos and honeybush — a natural preservatives. The Discrete Choice Experiment (DCE) approach elicited willingness to pay for the innovative alternative. Consumers' preferences for organic wine, wine quality, and cost were also examined. Results from the mixed logit model indicate that consumers are willing to pay additionally R60.40 per bottle of wine with natural preservatives, while they are ready to pay R19.45 more for organic wine and R1.55 for each point on quality score. Chapter 5 investigates the robustness of the empirical estima
