    This paper quantitatively examines by simulation the extent to which plot exchange can consolidate fragmented farmland. We first show that individual, decentralized, one-to-one plot exchanges, which are currently conducted by some leading farmers, cannot accomplish sufficient consolidation. This is because occurrences of "double-coincidence-of-wants" necessary for voluntary exchange are too few. We then propose a collective, centralized approach, based on the top trading cycle algorithm by Shapley et al., in which many farmers simultaneously exchange plots. This approach mitigates the restriction of "double-coincidence-of-wants" and can raise the consolidation rate to more than twice that of the individual-decentralized exchange. We also find that the consolidation rate improves dramatically as more farmers participate in the exchange. Our results suggest that it is essential to attract as many farmers as possible and to conduct collective and centralized allocation of plots in order to attain better consolidation.

    This study investigates the relationship between female labor participation and social customs in a rural area of Mediterranean Turkey, and examines how and to what extent existing social customs restricting female labor supply would constrain the effects on agricultural production and farm behavior of Turkey’s accession to the European Union (EU). Based on the results obtained in a field survey, a household model incorporating social customs is constructed that demonstrates the effects of divergence from standard female labor participation rates in crop production. Using this model, computable general equilibrium simulation analyses of Turkey’s accession to the EU are conducted. The results show that although social customs may restrain agricultural production by limiting female labor participation in crop production, their restraining effects are not as large as the effects of the changed production circumstances that would be caused by Turkey’s accession to the EU.
