Preliminary Impacts of a New Seasonal Work Program on Rural Household Incomes in the Pacific AgEcon
Gibson, John; McKenzie, David.
Seasonal work programs are increasingly advocated by international aid agencies as a way of enabling both developed and developing countries to benefit from migration. They are argued to provide workers with new skills and allow them to send remittances home, without the receiving country having to worry about long-term assimilation and the source country worrying about permanent loss of skills. However, formal evidence as to the development impact of seasonal worker programs is nonexistent. This paper provides the first such evaluation, studying New Zealand's new Recognized Seasonal Employer (RSE) program which allows Pacific Island migrants to work in horticulture and viticulture in New Zealand for up to seven months per year. We use baseline and...

Agricultural Technology Adoption and Rural Poverty: Application of an Endogenous Switching Regression for Selected East African Countries AgEcon
Asfaw, Solomon; Shiferaw, Bekele A..
Achieving agricultural growth and development and thereby improving rural household welfare will require increased efforts to provide yield enhancing and natural resources conserving technologies. Agricultural research and technological improvements are therefore crucial to increase agricultural productivity and thereby reduce poverty. However evaluation of the impact of these technologies on rural household welfare have been very limited by lack of appropriate methods and most of previous research has therefore failed to move beyond estimating economic surplus and return to research investment. This paper evaluates the potential impact of adoption of modern agricultural technologies on rural household welfare measured by crop income and consumption...

Synergistic Green and White Revolution: Evidence from Kenya and Uganda AgEcon
Jia, Xiangping.
Rising agricultural productivity in developing countries is crucial to ease the tension of increased population and haunting concern on food security. Nevertheless the soaring price of fertilizer and sluggish dissemination of improved seed varieties prohibit the poor to tap benefits from increased productivity. In the presence of the pressing button on food security, subsidizing fertilizer and seeds is recently voiced heavily. This study reveals that the adoption of improved maize variety in Kenya leads to higher yield than that in Uganda. By introducing livestock programs, the agricultural productivity in Kenya is sustained with a synergy between the “Green Revolution” and “White Revolution”. To tap agricultural potentials in Africa, subsidizing...

Evaluating the Effects of Farm Programs: Results from Propensity Score Matching AgEcon
Pufahl, Andrea; Weiss, Christoph R..
The paper applies a non-parametric propensity score matching approach to evaluate the effects of two types of farm programs (agri-environment (AE) programs and the less favoured area (LFA) scheme) on input use and farm output of individual farms in Germany. The analysis reveals a positive and significant treatment effect of the LFA scheme for farm sales and the area under cultivation. Participants in AE schemes are found to significantly increase the area under cultivation (in particular grassland), resulting in a decrease of livestock densities. Furthermore, participation in AE programs significantly reduced the purchase of farm chemicals (fertilizer, pesticide). We also find substantial differences in the treatment effect between individual farms...

Exploiting spatial and temporal variations in residential subdivision development to identify urban growth spillovers AgEcon
Towe, Charles A.; Klaiber, H. Allen; Wrenn, Douglas H.; Newburn, David A.; Irwin, Elena G..
Minimum lot size zoning requirements are a frequent policy tool used to restrict the density and location of residential development. Zoning regulations are typically instituted and adopted locally, often with limited input from surrounding jurisdictions. Autonomous local land use regulations that constrain some, but not all development within a region create discrete differences in the returns to development across otherwise similar locations and are hypothesized to lead to a lower density, more scattered land development pattern. We examine the rural down-zoning policy in Baltimore County, Maryland in 1976 and its potential effect on creating urban growth spillovers in the adjacent counties. Using propensity score matching methods combined with a...
