Abstract:

Worsening environmental conditions threaten to undermine progress in reducing rural poverty. Little is known, however, about the prospects for farmer adaptations to mitigate this threat, in particular through opportunities for income diversification presented by recent non-agricultural growth. We study the effects of increasing water scarcity in India using quasi-random, geologically determined differences in access to groundwater. The drying up of wells results in a precipitous and persistent decline in farm income and wealth, with little evidence of agricultural adaptation. However, labor re

Abstract:

We model farmers as facing small fixed costs of purchasing fertilizer and assume some are stochastically present biased and not fully sophisticated about this bias. Such farmers may procrastinate, postponing fertilizer purchases until later periods, when they may be too impatient to purchase fertilizer. Consistent with the model, many farmers in Western Kenya fail to take advantage of apparently profitable fertilizer investments, but they do invest in response to small, time-limited discounts on the cost of acquiring fertilizer (free delivery) just after harvest. Calibration suggests that this

Abstract:

Introduction Due to recent changes in acute leukemia treatment, there is an urgent need for greater understanding of the factors affecting quality of life at different points in the journey of patients. The Acute Leukemia Advocates Network (ALAN) is running a multi-country survey to gather information on the experiences, quality of life and symptoms of adults (16+) with different types of acute leukemia. The study objectives were to: (1) investigate whether the HM-PRO scores differ according to disease state; (2) determine whether those with worse scores on Q13-Q18 (patient-reported experience

Abstract:

We examine the role of delivery of subsidized seeds and fertilizers in the form of agricultural minikits by local governments in three successive farm panels in West Bengal spanning 1982–1995. These programs significantly raised farm value added per acre, accounting for almost two-thirds of the observed growth. The estimates are robust to possible endogeneity of program placement, controls for farm and year effects, other programs of agricultural development, local weather, and price shocks. The effects of the kits delivery program overshadowed the effects of other rural development programs,

Why do developing countries fail to specialize in products in which they appear to have a comparative advantage?

The model highlights the importance of infrastructure in aligning production outcomes with comparative advantage and sheds lig

The TseTse fly is unique to Africa and transmits a parasite harmful to humans and lethal to livestock. This paper tests the hypothesis that the TseTse reduced the ability of Africans to generate an agricultural surplus historically.

These correlations are not found in the tropics outside of Africa, where the fly does not exist. The evidence suggests current economic performance is affected by the TseTse through

We addressed the functional consequences of aberrant Op18 expression in leukemias by analyzing the cell cycle of K562 cells either depleted of Op18 by expression of interfering hairpin RNA or induced to express wild-type or Q18E substituted Op18.

Abstract:

AbstractThis paper shows how the hedonic approach to vineyard site selection can be used in the adaptation of vineyard land to climate change, natural disasters or other exogenous events. The basic idea is that, if the relation between weather and grape quality is known for each grape type in existing growing areas, then it is possible to predict the quality of grapes that would be produced in other locations, or in the same location with a changed climate. This permits the optimization of grape type selection for a location and also provides an indication of the value that a particular planti

Abstract:

We constructed co-integration relation and Engle–Granger type error-correction models for the wholesale potato markets of three Indian regions. In addition to the standard result of the existence of error-correction mechanisms in Indian potato markets, the chosen setting allows for inspection of how these market areas differ in their return to the co-integrating relation. The northern area differed from the other market relations studied with its slower return to equilibrium, 8.0–8.6 weeks compared to 5.0–6.3 weeks. The result may indicate that the Delhi and Agra markets are central playing gr

This study measured the technical, allocative and economic efficiencies of maize production in the central rift valley of Ethiopia using cross sectional data collected from randomly selected 138 sample households. The estimated result showed that the mean technical, allocative and economic efficiencies were 84.87%, 37.47% and 31.62% respectively. Among factors hypothesized to determine the level of efficiency scores, education was found to determine allocative and economic efficiencies of farmers positively while the frequency of extension contact had a positive relationship with technical eff

Abstract:

Prices of agricultural commodities tend to be more volatile in comparison to other commodities. Volatility can result in inefficient allocation of the resources by the farmers, traders and consumers. Rice is the second major staple and export item of Pakistan. This study presents the trends in volatility of regional rice markets of Pakistan and analyses spatial differences in volatility across regional rice markets in Pakistan from 1994 to 2011, and also draws comparison of volatility with the international market. ARCH-LM tests are applied to check the presence of volatility and volatility cl

Abstract:

Following the post-1992 Common Agricultural Policy, organic farming has expanded rapidly in the European Union. This growth is often considered evidence of the success of a distinctive model of small-scale family-farm agriculture. However, I show that European organic farms display features (large farm size, low labor intensity, high prevalence of mechanization, and adoption of monocultures) that are characteristic of capitalist rather than peasant farms. These features raise doubts about whether European organic farming exemplifies repeasantization. JEL Classification: B50, O13, Q18

The intent is to demonstrate how a nonparametric regression based on a rank-based estimator can be used to estimate a Cobb-Douglas production function using data on maize production from Ghana. The nonparametric results are compared to common parametric specification using the ordinary least squares regression. Results of the study indicate that the estimated coefficients of the CobbDouglas Model using the Least squares method and the rank-ba

Abstract:

The literature on the capitalization of agricultural policies documents that government subsidies can increase farmland values with attesting empirical evidence found in a variety of agricultural programs. This study argues that the well-documented capitalization effect of agricultural subsidies on farmland prices may not be directly related to the agricultural disaster relief program (ADRP). On the one hand, disaster relief payments can positively capitalize into farmland prices. On the other hand, disaster shocks may result in farm income loss which can decrease farmland prices.

We draw on international time-series data from a large number of countries that experienced different patterns of climate change and influences of policy and demand shifts. We find systematic patterns that suggest that rising wine alcohol content may be a nuisance by-product of producer responses to perceived market preferences for wines having more-intense flav

Abstract T-prolymphocytic leukemia (T-PLL) is an aggressive T-cell leukemia characterized by the proliferation of prolymphocytes with a mature postthymic T-cell phenotype and commonly involves the blood, bone marrow, lymph nodes, liver, spleen, and skin. Leukemic cells appear as small to medium-sized prolymphocytes or small variant cells, occasionally with cerebriform nuclei. T prolymphocytes are CD2+, CD3+, and CD7+ and may express CD4+CD8−, CD4+CD8+, or CD4−CD8+ markers. The most frequent chromosomal abnormalities are t(14;14)(q11;q32), inv(14)(q11q32), t(X;14)(q28;q11), i(8)(q10), and t(8;8

Conjoint analysis was used to calculate average importance for the three attributes.
