The Response of Consumption to Income Shocks: Evidence from the Indian Trade Liberalization

This paper uses the Indian tariff reforms of the early nineties to estimate how households responded to the negative income shocks caused by the tariff decreases. Households more hurt by the tariff reform decreased overall expenditure, but the response is not uniform across food items. In particular, households more hurt by the reform did not change their consumption of cereals, but decreased their consumption of all other food items. Although this coping mechanism helped maintain overall levels of calorie consumption, diet diversity and the associated benefits were sacrificed.Nutrition, Trade, Development, Food Consumption/Nutrition/Food Safety, Food Security and Poverty, International Development, D7, D8, H2, O2,

Growth and Equity Effects of Agricultural Marketing Efficiency Gains in India

Agriculture is the largest source of employment in India, and food accounts for about half of consumer expenditures. Moving agricultural products from the farm to consumers more efficiently could result in large gains to producers, consumers, and India’s overall economy. This analysis uses a computable general equilibrium model with agricultural commodity detail and households disaggregated by rural, urban, and income class to study the potential impacts of reforms that achieve efficiency gains in agricultural marketing and reduce agricultural input subsidies and import tariffs. More efficient agricultural marketing generates economywide gains in output and wages, raises agricultural producer prices, reduces consumer food prices, and increases private consumption, particularly by low-income households. These gains could help to offset some of the medium-term adjustment costs for some commodity markets and households associated with reducing agricultural subsidies and tariffs.India, agriculture, policy reform, marketing efficiency, tariffs, subsidies, households, computable general equilibrium model., Agricultural and Food Policy, Agricultural Finance, Crop Production/Industries, International Relations/Trade, Marketing,

Definition study for photovoltaic residential prototype system

A site evaluation was performed to assess the relative merits of different regions of the country in terms of the suitability for experimental photovoltaic powered residences. Eight sites were selected based on evaluation criteria which included population, photovoltaic systems performance and the cost of electrical energy. A parametric sensitivity analysis was performed for four selected site locations. Analytical models were developed for four different power system implementation approaches. Using the model which represents a direct (or float) charge system implementation the performance sensitivity to the following parameter variations is reported: (1) solar roof slope angle; (2) ratio of the number of series cells in the solar array to the number of series cells in the lead-acid battery; and (3) battery size. For a Cleveland site location, a system with no on site energy storage and with a maximum power tracking inverter which feeds back excess power to the utility was shown to have 19 percent greater net system output than the second place system. The experiment test plan is described. The load control and data acquisition system and the data display panel for the residence are discussed
