This paper investigates the extent dynamics and factors influencing technical efficiency (TE) and capacity utilization (CU) in small-scale fisheries (SSF) using a two-stage data envelopment analysis (DEA) approach covering the period 2010“2012. A considerable extent of boat-level technical inefficiency capacity underutilisation and scale inefficiency were evident. On average TE and CU levels under the constant returns to scale (CRS) and variable returns to scale (VRS) models declined over time. The TE and CU scores of 2010 remained unaltered with the addition of fishing time as an input to the model. The proportion of boats with unitary scale efficiency (SE) decreased from 26 in 2010 to 12 in 2012. The underutilisation rates of the inputs crew and fishing time ranged from 15.5 to 31.6 and 15.8 to 28.6 respectively. Among the species category the extent of excess capacity was 70 to 156 and 47 to 119 under the CRS and VRS models respectively. The second-stage DEA results indicated that the explanatory variables fishing location catch per unit of effort (CPUE) fuel costs and crew share significantly influenced CU under the CRS model. In contrast the significant influence of subsidies and other operating costs were noted under the VRS model. For the TE case age education subsidy and CPUE were found to be significant under the CRS and VRS models. Other significant variables were found in the study under CRS and VRS models. Finally the results from the descriptive and empirical analysis under the two-stage DEA model are discussed together with policy implications.

Abstract

This paper investigates the extent dynamics and factors influencing technical efficiency (TE) and capacity utilization (CU) in small-scale fisheries (SSF) using a two-stage data envelopment analysis (DEA) approach covering the period 2010“2012. A considerable extent of boat-level technical inefficiency capacity underutilisation and scale inefficiency were evident. On average TE and CU levels under the constant returns to scale (CRS) and variable returns to scale (VRS) models declined over time. The TE and CU scores of 2010 remained unaltered with the addition of fishing time as an input to the model. The proportion of boats with unitary scale efficiency (SE) decreased from 26 in 2010 to 12 in 2012. The underutilisation rates of the inputs crew and fishing time ranged from 15.5 to 31.6 and 15.8 to 28.6 respectively. Among the species category the extent of excess capacity was 70 to 156 and 47 to 119 under the CRS and VRS models respectively. The second-stage DEA results indicated that the explanatory variables fishing location catch per unit of effort (CPUE) fuel costs and crew share significantly influenced CU under the CRS model. In contrast the significant influence of subsidies and other operating costs were noted under the VRS model. For the TE case age education subsidy and CPUE were found to be significant under the CRS and VRS models. Other significant variables were found in the study under CRS and VRS models. Finally the results from the descriptive and empirical analysis under the two-stage DEA model are discussed together with policy implications.
