Money for Wine? Complementarities in the Provision of Private and Public Goods to Wine Producers

This paper evaluates the impact of two programs that provide public and private goods, in the form of irrigation canals and materials (such as hail nets). Using a twelve-year panel of wine producers from Mendoza and San Juan, Argentina, we find that the programs have had positive and significant impacts on production and yield. We also find that the programs present important complementarities, in the sense that being exposed to the two interventions increases the outputs more than the mere sum of the separate interventions.
