Venice, December 29 - Fuel and electronic goods prices fell while fruit and vegetable prices rose in 2015, according to research released Tuesday by CGIA Mestre, which represents small and medium-sized businesses. The report pointed to steep drops in prices for methane gas (-17.8%), car diesel fuel (-12.3%), heating gas (-11.8%), computers and tablets (-11.7%), cell phones (-10.1%), and car petrol (-9,8%). At the same time, drought on the production end drove up the prices of oranges (+10.8%), vegetables (+9,7%), berries (+8.9%), other citrus fruits (+7.4%) and olive oil (+6.1%). Families spent more on fruits and vegetables (an average of 97.40 euros a month) than on meat (97.20 euros a month). This was due to summer heat, and healthier Italian eating habits, with spending on animal protein falling steadily since 2011, the CGIA report said. However speculation by intermediaries in a highly fragmented distribution system also drove prices up 500% in some cases, CGIA said. Prices this year fell in three out of 12 spending sectors, according to the CGIA Mestre report. Transportation prices fell 2.6%, communications fell 1.3%, and the aggregate of housing, electricity and fuel fell 0.9%. Hotel and restaurant prices added 1.2%, education rose 1.8%, and alcohol and tobacco rose 2.7%, the report said.
