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,

DBQ: Document-Based Quarantine

This paper presents how one school and one special library handled the first months of quarantine and remote teaching and learning as COVID-19 hit the United States in spring 2020. While teaching with archives has long been a part of the professional discourse within the archival and special collections community, changes in methodology in teaching remotely and modifications to the Advanced Placement United States History (APUSH) exam’s document-based question (DBQ) called for experimentation and innovation. The collaboration between APUSH teachers at Woodbridge Senior High School in Virginia and the Friends Historical Library at Swarthmore College in Pennsylvania provided one solution to preparing students for the modified AP exam. The authors of this paper explore the background and context of the work of teachers and archivists, describe the actions taken in spring 2020, and analyze the results and impact. Lessons learned and future opportunities for collaboration are then examined. The paper concludes with a proposal that similar relationships and activities are not just possible but also beneficial for all involved

Variables affecting the distributive impact of employment in new manufacturing industry in rural Tennessee

This study utilizes primary data collected from a sample of new rural Tennessee manufacturing plants and employees to investigate the extent to which changes in the family and wage incomes of new employees are affected by individual, family, plant, and community characteristics. The sample data are also used to estimate the primary round impact of new manufacturing employment on the distribution of income and the alleviation of poverty in the sample counties. Multiple regression analysis is used to identify the relationship between changes in family income resulting from employment in the sample plants and worker, family, plant, and community characteristics hypothesized to influence these changes. The most important variables are those measuring changes in the labor force participation of family members which coincide with employment in the sample plants. Gains in public assistance and other incomes, years of education, plant relative size, and plant relative wage levels have significant direct relationships with income changes, while losses of public assistance and other incomes, county rates of underemployment, return migrant status, and, unexpectedly, plant skill requirements have significant inverse relation ships. Correlations with family labor force participation patterns are identified as explanations for the insignificance of worker age and sex and commuter and migrant status. Multiple regression analysis is also used to explore the relationship between worker, plant, and community characteristics and changes in employee annual wage earnings. Change in worker employment status at job entry is the most significant determinant of overall wage changes. Employee sex and years of education, change in family size, plant relative size and relative wage levels, plant skill requirements, county rates of unemployment and underemployment, and commuter and return migrant status are also significant determinants of changes in wage earnings. Variations in the degree to which workers are underemployed in previous jobs and in jobs in the sample plants are identified as a consistent explanation for the insignificance of some variables as well as the unexpected inverse relationship between plant skill requirements and income changes. The primary round distributive impact of employment in new manufacturing plants is described by comparing the incomes of sample families before and after employment in the sample plants to the estimated distribution of family incomes in the sample counties. While the frequencies of families in the middle quintiles of the distribution increases after employment, relatively few of the families are in the lowest income quintile before employment. Local workers compete extensively for income gains with migrating and, especially, commuting workers. Employment in the sample plants enables most previously poor families to escape poverty, but the vast majority of sample families are not previously poor. The results of the analysis indicate that factors affecting the participation of family members in the manufacturing workforce and the underemployment of rural workers are key determinants of how new manufacturing industry changes incomes and the distribution of incomes in rural communities. The characteristics of new manufacturing plants appear to affect family labor force participation patterns and the opportunities rural workers have to become more fully employed
