We analyze the extent of participation over an 11-year time period using correlated random effects and diff-GMM models and explain the hazards of dropping out of the export chain based on a multi-spell cox duration model. The empirical results suggest that small-scale farmers' exit from the export sector is accelerated by hold-ups experienced in the past and that family ties play an important role in farmers' marketing decisions. Negative external shocks – such as the global financial crisis starting in 2007 that was associated with the bankruptcy of the main buyer in our case study – represent a major threat towards the sustainability of smallholder inclusion in high-value chains}, url = {http://ageconsearch.umn.edu/record/209961}, doi = {https://doi.org/10.22004/ag.econ.209961}, }
