This data can be found from the World Health Organization (WHO). For the average price of alcoholic beverage, we use the Harmonized Index of Consumer Prices (HICP) of alcoholic beverage, which is supplied by eurostat, as the proxy. For the retail sales and price variables of other commodities (household equipment; textiles, clothing, footwear, and leather goods; books and stationary; motor cars; and total retail sales) we use the Retail Trade Turnover Index (RTTI) of each sector as the proxy of the amount of retail sales, while we use the Harmonized Index of Consumer Prices (HICP) as the proxy of the average price of each commodity. All data on the Retail Trade Turnover Index (RTTI) and Harmonized Index of Consumer Prices (HICP) is provided by eurostat.
