    Do corporately organized wine producers cope better with unfavorable weather conditions than private wine estates? Hedonic pricing models for South African wines

    In our research we want to estimate the effect of changing weather conditions on south African wine prices for both, small wine estates and corporately organized producers and to compare these results. We assume that the latter cope better with unfavourable weather conditions than private wine estates, whereas beneficial weather will be favourable for both of them. We focus on the South African domestic wine market, as prices on export markets are additionally influenced by other factors, such as marketing strategies, certifications, mark ups of wholesalers or retailers etc.

    We assume that each region has its own competitive advantage in growing certain grape varieties, as all varieties have different capabilities to cope with specific weather or climate conditions. In this paper we first analyze the effects of annual weather changes on yields in order to find, which weather is advantageous for which grape variety. This analysis should lead to some kind of ideal weather scenario for each grape variety (like dry and sunny with small rain etc.). In as second step the changing weather conditions in each region are reconciled with these scenarios in order to give recommendations where different grape varieties should be grown. In the third step we compare our recommendations with the distribution of grape varieties in South African wine regions and the uprooting and planting behavior of grape growers.
