Efficiency analysis of Italian wine producers

Efficiency of wine grape growers at farm level: a case study

“…The second step studies the determinants of the inefficiency on farms alongside a brief econometric analysis with a Tobit model that can be expressed by equation (3) [19]. (3) where is the efficiency level of the j-th farm obtained by DEA, is the estimated coefficient for the intercept, is a matrix assembled by the explanatory variables of the respective vectors, β is a vector of the estimated coefficients, and is the stochastic error.…”

“…Marta-Costa et al [12], Freitas [13], Coelli and Sanders [14], Moreira et al [15] and Henriques et al [16] put their efforts into studies that aim the efficiency calculation of the grape producers, while Sellers-Rubio et al [17], Sellers-Rubio & Más-Ruiz [18] and Aparicio et al [10] studied the efficiency at the wineries level. Urso et al [19] acquaint the efficiency of grape and wine producers in the same paper. Tóth & Gál [20] research the efficiency of wine producers at a country level and Vidal et al [21] study the efficiency of the different denomination of origin (DO) existing in Spain.…”

“…Tóth & Gal [20], Coelli & Sanders [14], Moreira [15] and Freitas [13] studied the quantity of output produced, while Marta-Costa et al [12], Urso et al [19], Sellers-Rubio et al [17], Sellers-Rubio & Más-Ruiz [18], Aparicio et al [10], Vidal et al [21] and Henriques et al [16] studied the value of output that was produced. Regarding the input variables, there are three variables mostly used in the precedent articles: labour, capital and land.…”

“…The variables used to determine the causes of inefficiency in the wine sector are not consensual. Some are related to inner characteristics, such as the size of the farm and the farmer's gender, age education [16,19,22]. Meanwhile other efforts pointed out other features such as the diversification/specialization of products [14,16], irrigation [14,16,22], credit access, quality of human capital and per capita wine consumption [23].…”

Antioxidant Species in Grapes and Wines via Spectrophotometric Methods: No Quenching Effects by Copper(II) and Yeast Derivative Treatments

“…e costs of production, storage, marketing, care for consumers' health increased significantly, because the beverage requires an extreme care for each stage of production: from vines and grapes growths throughout commercialization. Wine market has a relevant role for financial budgets for several countries, and it is estimated to sum up to many tens of billions Euro/year [3,4].…”
