The development of rural infrastructure is an important component in improving the standard of living in developing countries. In India, the government has taken up numerous measures to contribute toward the development of rural infrastructure, thereby initiating the Bharat Nirman Yojana (BNY). In this research study, the Malmquist model of input‐oriented DEA has been conducted to determine the efficiency of six schemes of the BNY for the time period of 2013–2015. The input variables selected were; designated investment and total amount released by the central government against the output variable of number of villages covered or achieved. The analysis of the data observed that only the telecommunication scheme has constant efficiency of 1.000 for all the years. On the other hand, the least efficiency from the Constant Return to Scale model was found for Accelerated Irrigation Benefit Programme (AIBP) (0.014 for 2013; 0.026 for 2014 and 0.007 for 2015). Again, the Variable Return to Scale model indicated technical efficiency for the electrification scheme and telecommunication for all the years. Further, in terms of technical efficiency, all the schemes had decreasing change where Pradhan Mantri Gram Sadak Yojana (PMGSY) showed the highest change with 99.98% and the telecommunication scheme reflected the least change. Furthermore, the productivity index was found to be highest for Telecommunications (1.443) followed by AIBP (1.312), and the lowest productivity index was found for Rajiv Gandhi Gramin Vidyutikaran Yojana (RGGVY) (0.353). Thus, it was interpreted that among all the schemes, telecommunications scheme was the most efficient. [ABSTRACT FROM AUTHOR]

Economists have argued that role of agriculture is pivotal for economic development of the nation. Worldwide studies have shown that agriculture sector is more effective in reducing hunger and poverty than other sectors. This study is an attempt to ascertain the importance of agriculture in the economic growth of West Bengal. Agriculture, being the source of livelihood and supplier of raw material to various industries, triggers economic growth of the nation. This paper exhibits how agriculture has contributed to West Bengal's economic excellence using empirical data and a cointegration analysis. The role of agriculture is examined on four contributions: (a) product contribution (forward linkage), (b) market contribution (backward linkage), (c) factor contribution, and (d) foreign exchange contribution. The composition and growth of the sectors and its association with other sectors is analyzed using time series analysis. Findings of the study revealed that agriculture sector has appeared as an important contributor to drive West Bengal economic growth even after declining share in gross state domestic product over the years. Empirical analysis reveals that agriculture is having long run causal linkages with industry, services, and overall economic growth in West Bengal. [ABSTRACT FROM AUTHOR]
