| The analysis proposed in this paper is concerned with the welfare effects of self-regulation by Producer's Organizations (PO) as an alternative to market or public intervention. Using the advances of the economics of incentives, it studies the interaction of asymmetric information and the democratic process in the quality choices of a group of heterogenous producers. With a simple model of adverse selection it presents the pricing rules and the quality provision in a group of producers facing an opportunity to gain from their collective capacity to establish a reputation for their quality products. This paper explicitly considers the democratic process through which quality-based reward schemes are decided upon and enforced in the PO. It distinguishes... |

| We consider the welfare impact of the mandatory and voluntary labelling to inform consumers on GMOs content in foods. With a model of vertical differentiation in competitive markets, we evaluate the effects on price equilibrium and welfare levels. We find that the mandatory labelling scheme would be optimal in those countries with more GMO-averse consumers and no-GMOs practices producers. Voluntary labelling would instead optimally be chosen in those countries where producers are using GMOs and consumers are more concerned about the costs savings resulting in this technology adoption. |

| In this paper we consider the role for collective action in advertising investments needed to compete on foreign markets and/or to enter into new markets. We model the choices facing producers in regions where both AO (high quality) and table (low quality) wines are produced. By joining forces with producers of other regions to invest in advertising, producers may penetrate into new markets. We show that it is profitable to enter into the new markets when, other things being equal, the size of the new market is relatively big, when the traditional market is relatively small, and when the size of the fixed investment in advertising is relatively small. We discuss the policy implications of the results, examining possible modifications of the AO system... |

| In this paper we propose a methodology to measure the characteristics and composition of intermediate products using productivity indicators based on directional distance functions. We evaluate how quality attributes interact with the quantity level in grapes production, and find evidence of a trade-off between quantity and aggregate quality for Chardonnay. |
