Abstract

The paper identifies the sources of changes in energy consumption and GHG emissions in India using Input-Output Structural Decomposition Analysis (SDA) during the period 1993-1994 to 2003-2004. The result shows that changes in final demand structure and volume of changes in final demand are the key factors responsible for changes in energy requirements and GHG emissions respectively. It further develops few simulation exercises to estimate the energy requirements and GHG emissions during the Twelfth Plan. The implications of these scenarios provide a better insight for the derivation of future policy towards reduction in energy consumption resulting in climate change impact.

Abstract

The Government of India has enacted National Food Security Act, 2013 (NFSA). This paper measures the impact of implementing this Act on production structure of the economy. It applies modified Leontief and Ghosh models in Input-Output framework. A price model was also attempted to see the impact on sectoral prices. Results reveal that few sectors need to move in tandem to keep balance with food grain production. Overall, the country needs to gear up in terms of food grain productivity, otherwise NFSA must be supplemented by import which would entail a heavy burden on the exchequer.

Abstract

India's economic reform was initiated in mid 1991 by the Government of India. Some strategies for energy sector were adopted. This paper investigates the pattern of energy consumption changes during reform period i.e., 1991-92 to 1996-97and various factors responsible for these changes based on Input/Output model. Here we develop a Structural Decomposition Analysis. Six different factors have been identified here: (i) Technical changes, (ii) Changes in final demand structure, (iii) Changes in the interaction term of technical changes and final demand structure, (iv) Changes in energy exports, (v) Changes in energy imports, (vi) Changes in energy change in stock. Then we separate technical changes and final demand structure again, which explain the energy consumption changes. The most significant role as revealed from the empirical results have been played by the final demand structure, technical changes and interaction term between final demand structure and technical changes.
