摘要:This paper analyzes the productivity convergence in the cashew nut sector of the Ceará State, Brazil. Instruments of spatial econometrics are applied since the hypothesis of spatial dependence cannot be rejected. From the significant results of Moran's I and LISA, we highlight that municipalities with high productivity are generally located close to others with high productivity. In turn, low-productivity municipalities are generally near low-productivity ones. The data also show that the convergence hypothesis cannot be rejected in any analyzed period. Under these conditions, convergence rates of 6.49%, 4.96% and 7.71% per year were estimated for the periods 2000-2007, 2008-2015 and 2000-2015, respectively. Finally, considering the period 2000-2007, it was identified that it would take about 13 years to eliminate 50% of the productivity gap separating this sector from its steady state. Regarding the periods 2008-2015 and 2000-2015, it would be necessary about 16 and 14 years, respectively.
