Agricultural Household-Firm Units: Adjustments to Change AgEcon
Findeis, Jill L.; Swaminathan, Hema; Jayaraman, Anuja.
This paper assesses agricultural household-firm unit models to determine a useful typology for agricultural policy assessment that draws upon their use. Both standard and bargaining models for analyzing household decisions, including production, consumption, labor, credit, fertility and child schooling, intergenerational transfer, among other key behaviors of households are discussed, as well as data and estimation issues often encountered with household models. Relevant dimensions of a country or region typology are then suggested, focusing on (1) the extent to which markets, particularly labor markets, are perfect, missing or mixed; (2) relevant intra-household and key demographic considerations; and (3) the differentiation of particular household-firm...

Allocation Effects of Policy Reform: A Micro-Simulation of Macro-Model Results for the United States AgEcon
Hopkins, Jeffrey W.; Hanson, Kenneth; Somwaru, Agapi; Burfisher, Mary E..
By changing marginal prices and therefore production incentives, removal of government payments will result in a re-allocation of factors of production as farm households pursue alternative economic opportunities. At the economy-wide level these impacts are small, but closer inspection reveals that some household-level impacts will be larger and other households will be affected little if at all. The underlying heterogeneity of the agricultural sector results in variable adjustment along two dimensions. First, survey data show that payments are not evenly distributed so their removal does not have a uniform impact across the sector. Second, even if payments were evenly distributed, factor endowments are not, so that ability to enter into alternative...

China’s water pricing reforms for irrigation: effectiveness and impact AgEcon
Liao, Yongsong; Gao, Zhanyi; Bao, Ziyun; Huang, Qingwen; Feng, Guangzhi; Xu, Di; Cai, Jiabin; Han, Huijing; Wu, Weifeng.
Irrigation occupies a central position in China’s crop production. However, due to low per capita water resources, much worse, unevenly distributed over regions and time and the rapid increase of water diversions to non-irrigation sectors, irrigation water shortages have become a very serious problem. Without the adoption of effective measures this problem may even threaten China’s food security. Currently, irrigation efficiency is very low in general, irrigation water prices cannot fully recover water supply costs, and irrigation facilities are aging due to the lack of funding for O&M (operation & maintenance). Since water prices are regulated by the government, and not determined by the market, water prices did not work effectively in water...

Designing REDD+ Schemes to Address Permanence Concerns: Empirical Evidence from Kenya AgEcon
Veronesi, Marcella; Schlondorn, Tim; Zabel, Astrid; Engel, Stefanie.
Reducing Emissions from Deforestation and Forest Degradation (REDD+) is an important topic in the debate on policies to mitigate climate change. This is the first study to test and compare the environmental impact of different REDD+ payment schemes in the field, and provide some insights on the effectiveness of different policies with respect to the permanence of forest-based emission reductions. This study implements a stated preference experiment of time allocation in the unique setting of the Kasigau Corridor REDD+ Project in Kenya, where charcoaling is a major source of forest degradation. The impact on time allocation is analyzed under the presumption that a hypothetical agricultural policy or an eco-charcoaling policy was introduced. We find that a...

Determining Educational Needs: A Focus Group Approach AgEcon
Eberspacher, Beth; Jose, H. Douglas.
The first step in planning and delivering a successful program is to identify the needs and interests of the target audience. The North Central Risk Management Education Center, which provides grants for educational programs for producers in the 12 north central states in the US, conducted a series of focus groups with producers. The goals of the focus groups were to: 1) determine the impact of funded programs; 2) assess risk management education needs of producers; 3) assess preferred delivery methods; and 4) determine program characteristics that will enhance participation. The participants had an average age of 45 which is about 12 years younger than the average age of all farmers. With 1,861 acres of owned and rented land, they had slightly larger...

Effects of contracts and work relationships on salaries and income distribution of workers in the Chilean agricultural sector, 1996 and 2006 Ciencia e Investigación Agraria
Campos,Jorge; Foster,William.
During the past thirty years the Chilean economy generally and agriculture specifically have grown considerably, raising both per capita GDP and observed real wages of salaried workers. There has been, however, a concern about the country's persistent unequal distribution of income. Among the possible factors associated with income inequality is the relatively infrequent use of contracts in seasonal and occasional work, both strongly present in agriculture. Based on Chilean household surveys (CASEN) for 1996 and 2006, impacts of contracts and work relationships (permanent, seasonal, etc.) on salaries, and their possible contributions to inequality, were measured, accounting for schooling, ethnicity, work experience, geographic zones, and other variables...

Implications of Immigration Policies for the U.S. Farm Sector and Workforce AgEcon
Devadoss, Stephen; Luckstead, Jeff.
We develop a theoretical model using migration and trade theory to examine the effects of domestic and border enforcement policies on unauthorized workers and the U.S. agricultural sector. The theoretical results show that heightened immigration policies increase the illegal farm wage rate, and reduce the employment of unauthorized farm workers and exports. The empirical analysis show that increased domestic enforcements curtail the number of undocumented farm workers by an average of 8947 and commodity exports to Mexico by an average of $180 million. The tighter border control curbs illegal farm workers by 8147 and reduces farm exports by $181 million.

Intersectoral Migration in Southeast Asia: Evidence from Indonesia, Thailand, and the Philippines AgEcon
Butzer, Rita; Mundlak, Yair; Larson, Donald F..
Using time-series data spanning three decades, we examine the determinants of sectoral migration in Indonesia, Thailand, and the Philippines. We used a principal-components algorithm to address the problems associated with trended and intercorrelated explanatory variables. Migration rates in the three countries are low relative to other developing countries, with the consequence of persistent intersectoral income differentials. Even so, the rate of migration has been responsive to the income ratios in each country. The migration rates were also affected by the absorbing capacity of nonagriculture, as indicated by several measures. In contrast to other studies, policy variables consisting of indicators of physical and human capital had little impact on...

Intravaginal progestagen for estrus and parturition control in sows Repositório Alice
GASPERIN, B.G.; FRELING, G.F.; FERREIRA, R.; OLIVEIRA, J.F.C. de; BORDIGNON, V.; GONÇALVES, P.B.D..
The objective of this work was to evaluate the use of intravaginal devices (IVD) for the control of reproductive events in swine. Sows at 112 days of pregnancy received an injection of PGF2á (control, n = 15) or PGF2á plus an IVD containing medroxyprogesterone acetate (IVD group, n = 14) for 48 hours. Sows initiated labor 27.7±1.6 and 82.3±3.8 h after PGF2á aplicaction, in control and treated groups, respectively. Regarding control of estrus cycle, ten sows received IVD for 12 days starting immediately after weaning, and estrus was confirmed 17.25±0.17 days after weaning, in comparison to 4.00±0.25 days for the control group. Intravaginal devices with progestagen can be applied for the control of reproduction in swine.
