    Quality Strategies in Frictional Search Models
    (Wiley, 2025-05-05)
    Morganti, Paolo Riccardo  
    We explore quality-based strategies in frictional online markets using a targeted search model with vertical differentiation and heterogeneous agents. Firms self-select into high- or low-quality segments and compete in prices. We demonstrate that reduced search costs amplify the prominence of quality, leading to an increase in the market share of high-quality designs. While low-quality firms dominate when cost differentials are large, declining search frictions amplify the prominence of the quality attribute. The raised importance of quality triggers dual effects: a higher price sensitivity, leading to further price reductions across all products, and a boost in demand for high-quality designs. Our findings offer insights into the recent dynamics of online markets, explaining the expansion of high-quality segments and providing a strategic framework for firms to navigate evolving consumer preferences in increasingly transparent markets. ©The author ©Journal of Economics & Management Strategy ©Wiley.

    Achieving sustainable agri-food systems (SAS) requires the collaborative work of multiple participants. Using a systemic analytical approach, the limiting factors for the sustainable transition of the agri-food system (AS) of the Mexican avocado value chain (VC) were studied. International, national and government data sources were consulted and complemented by three case studies. Short-term policies, current VCand AS governance structures, inadequate infrastructure for the sustainable use of natural resources and insecurity limit the achievement of the SAS. Acceptable economic indicators for the sector should allow for social and environmental improvements by introducing more efficient irrigation systems and improving current working conditions. ©Universidad Nacional Autónoma de México, Instituto de Investigaciones Económicas
