| Summary: | This paper investigates the impact of environmental constraints on efficiency of Bangladeshi rice (AUS, AMAN and
BORO) using data from year 1989 to year 2008.Constant Returns to Scale (CRS) and Variable Returns to Scale (VRS)
Data Envelopment Analysis (DEA) efficiency scores indicate technical efficiencies.The results show that technical
efficiency (TE) of AUS in both CRS and VRS DEA is lowest in 2004.But for AMAN and BORO in case of CRS DEA, TE is
lowest in 1998 and 1992.We applied a Tobit model to evaluate the effects of environmental constraints on
technical efficiencies.We regressed TE of AUS, AMAN and BORO with environmental constraints Rainfall, humidity
and temperature to weigh up the impact on TE.For AUS and AMAN, humidity is found positive and significant whereas rainfall and temperature are observed negative but not significant.For BORO, humidity and rainfall are recorded positive effect but temperature is found to be negative. |
