Grosová S., Masár M., Kutnohorská O., Kubeš V. (2017): Demand for beer in the Czech Republic: understanding long-term on-and off-trade price elasticities. Czech J. Food Sci., 35: 165-170.We provided estimates of price, cross-price, and income elasticities for on-and off-trade beer consumption using econometric models on time series data from 1994 to 2014. The empirical results indicate that the most important determinants of on-trade demand are the price of off-trade beer, the price of substitutes and past consumption, while the income elasticity was not found to be important. The most important determinants of off-trade beer demand were the price of on-trade beer and the price of substitutes. In the Czech Republic, there is a long tradition of beer consumption in pubs and restaurants. According to Vinopal (2007), beer drinking is often a social affair, so some prefer to drink beer in pubs compared to solitary household consumption of bottled beer. This shift in beer consumption from restaurants and pubs to retail or households could have a significant impact on traditional Czech pubs. In order to determine an optimal course of the reaction, it is necessary to find the causes of these phenomena. There are some reasons for this shift, one of them are changing relative prices. The real price per litre of on-trade beer has risen by 23% from 1994 to 2014; the real price of off-trade beer has fallen by 12% in the same time period. The fall of off-trade prices is largely caused by strong competition and heavy discounts of beer products in supermarkets. The other causes may stem from income changes and food-related life-style changes.
