UNDERSTANDING FARM-LEVEL TECHNOLOGY ADOPTION: LESSONS LEARNED FROM CIMMYT'S MICRO SURVEYS IN EASTERN AFRICA
Provedor de dados: 31
Autores: Doss,   Cheryl R.
Drawing on a series of technology adoption studies carried out by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with national agricultural research systems in Eastern Africa during 1996-98, this paper suggests alternative approaches for designing technology adoption studies to obtain as much useful information as possible. It describes the Eastern African studies and summarizes specific lessons learned, asks what can be learned from farm-level studies in a few communities, explores generic limitations of micro studies and a range of problems and issues faced in carrying out such studies, addresses challenges that arise in trying to put together a set of compatible micro studies, and lists overall conclusions and specific...

Are Household Production Decisions Cooperative? Evidence on Pastoral Migration and Milk Sales from Northern Kenya
Provedor de dados: 31
Autores: Doss,   Cheryl R.; McPeak,   John G.
Market-based development efforts frequently create opportunities to generate income from goods previously produced and consumed within the household. Production within the household is often characterized by a gender and age division of labor. Market development efforts to improve well being may lead to unanticipated outcomes if household production decisions are non-cooperative. We develop and test models of household decision-making to investigate intra-household decision making in a nomadic pastoral setting from Kenya. Our results suggest that household decisions are contested, with husbands using migration decisions to resist wives’ ability to market milk.

DO HOUSEHOLDS FULLY SHARE RISK? EVIDENCE FROM GHANA
Provedor de dados: 31
Autores: Doss,   Cheryl R.
Intrahousehold analyses provide new insights into how households make economic decisions.  Much of the work in economics has traditionally treated the household as a single economic actor, but a number of studies are providing evidence that the dynamics among household members affect the outcomes of household economic decisions. This paper contributes to our understanding of such models by incorporating the variability of individual incomes into the analysis of intrahousehold resource allocations, using detailed household survey data from Ghana.

WOMEN'S BARGAINING POWER IN HOUSEHOLD ECONOMIC DECISIONS: EVIDENCE FROM GHANA
Provedor de dados: 31
Autores: Doss,   Cheryl R.
In this paper, the percentage of assets held by women within the household is used as a measure of women's bargaining power. The assets used in this paper include land, savings, and business assets.  Using detailed household survey data from Ghana, I demonstrate that the share of assets owned by women has a significant impact on household expenditure decisions. This provides additional support for the notion that women's bargaining power can be measured, at least in some dimensions, and that women's bargaining power is an important determinant of household economic decisions.  It suggests that other measures  of women's bargaining power may also be useful for understanding household decisions.

The Maize Green Revolution in Kenya Revisited
Provedor de dados: 31
Autores: De Groote,   Hugo; Owuor,   George; Doss,   Cheryl R.; Ouma,   James Okuro; Muhammad,   Lutta; Danda,   Milton Kengo.
The maize green revolution, which increased maize yields through the use of improved varieties and fertilizer, has stalled since the mid-eighties in Kenya. This paper examines whether the stagnation of yields continued in the 1990s in spite of the implementation of the maize liberalization policies by the Kenya Government. Analysis of farm level surveys from 1992 and 2002 indicates slight increases in the use of improved maize varieties and fertilizer, but a substantial decrease in the intensity of fertilizer use. The econometric analysis suggests that the intensity of fertilizer use has a major effect on yield. The use of improved maize varieties, however, did not affect yield, suggesting that there are local varieties for some areas that do as well as...

EDUCATIONAL INVESTMENTS IN A SPATIALLY VARIED ECONOMY
Provedor de dados: 31
Autores: Mude,   Andrew G.; Barrett,   Christopher B.; McPeak,   John G.; Doss,   Cheryl R.
This paper presents a simple two-period, dual economy model in which migration options may affect the informal financing of educational investments.  When credit contracts are universally available and perfectly enforceable, spatially varied returns to human capital have no effect on educational investment patterns.  But when financial markets are incomplete and informal mechanisms subject to imperfect contract enforcement must fill the breach, spatial inequality in infrastructure or other attributes that affect the returns to education create spatial differentiation in educational lending and consequently, in educational attainment.  Although migration options can increase the returns to education, they can also choke off the informal finance on which...

MODELS OF INTRAHOUSEHOLD RESOURCE ALLOCATION: ASSUMPTIONS AND EMPIRICAL TESTS
Provedor de dados: 31
Autores: Doss,   Cheryl R.
This paper reviews and analyzes a literature that examines the  restrictiveness of focusing on households as single units of analysis.   In particular, this literature asks:  To what extent can we use the household as a unit of analysis, and when do we need to disaggregate the household and look at individual behavior within the household?  In this paper, I examine the different models of intrahousehold resource allocation and the empirical work they have generated.  Each of the models has a different set of assumptions about the four components of household decisions.  The assumptions and predictions of each of the main models of intrahousehold resource allocation are presented; then I discuss the empirical work that tests the validity of the assumptions...

HOW DOES GENDER AFFECT THE ADOPTION OF AGRICULTURAL INNOVATIONS? THE CASE OF IMPROVED MAIZE TECHNOLOGY IN GHANA
Provedor de dados: 31
Autores: Morris,   Michael L.; Doss,   Cheryl R.
Why do men and women adopt agricultural technologies at different rates? Evidence from Ghana suggests that gender-linked differences in the adoption of modern maize varieties and chemical fertilizer are not attributable to inherent characteristics of the technologies themselves but instead result from gender-linked differences in access to key inputs.

TWENTY-FIVE YEARS OF RESEARCH ON WOMEN FARMERS IN AFRICA: LESSONS AND IMPLICATIONS FOR AGRICULTURAL RESEARCH INSTITUTIONS; WITH AN ANNOTATED BIBLIOGRAPHY
Provedor de dados: 31
Autores: Doss,   Cheryl R.
Based on an extensive review of the literature on women farmers in Africa, this paper explores the potential reasons why women farmers have not adopted improved maize technologies and discusses the implications for agricultural research. Women farmers are often constrained by their lack of access to labor, land, and inputs. In addition, women may prefer different outputs than men. Finally, the dynamics of household decision-making affects technology adoption; roles and responsibilities within the household are often renegotiated when new technologies are adopted, and women may be reluctant to provide labor if they do not receive some of the benefits. Each section of this paper includes a number of questions that may provide insights into the gender roles...

THE INFLUENCE OF WETLAND TYPE AND WETLAND PROXIMITY ON RESIDENTIAL PROPERTY VALUES
Provedor de dados: 31
Autores: Doss,   Cheryl R.; Taff,   Steven J.
Using detailed residential housing and wetland location data, we determine relative preferences for proximity to four broad classes of wetlands, as expressed through housing values. Implicit prices for proximity to open-water and scrub-shrub wetlands are relatively higher than those for emergent-vegetation and forested wetlands.

Interpersonal, Intertemporal and Spatial Variation in Risk Perceptions: Evidence from East Africa
Provedor de dados: 31
Autores: Doss,   Cheryl R.; McPeak,   John G.; Barrett,   Christopher B.
This study investigates variation over time, space and household and individual characteristics in how people perceive different risks. Using original data from the arid and semi-arid lands of east Africa, we explore which risks concern individuals and how they assess their relative level of concern about these identified risks.  Because these assessments were gathered for multiple time periods, sites, households and individuals within households, we are able to identify the degree to which risk perceptions vary across time, across communities, across households within a community, and across individuals within a household.  We find the primary determinants of risk rankings to be changing community level variables over time, with household specific and...

MEN'S CROPS? WOMEN'S CROPS? GENDER PATTERNS OF CROPPING IN GHANA
Provedor de dados: 31
Autores: Doss,   Cheryl R.
Three issues regarding gender patterns of cropping in Ghana are examined to disentangle whether observed patterns are based on gender or on factors correlated with gender. First, can "men's" and "women's" crops can be distinguished in household survey data? Second, is gender is a determinant of crop choice?  Finally, which women grow "men's crops"?

Milk Money and Intra-Household Bargaining: Evidence on Pastoral Migration and Milk Sales from Northern Kenya
Provedor de dados: 31
Autores: Doss,   Cheryl R.; McPeak,   John G.
In this study, we investigate the impact of new market opportunities on Gabra nomadic pastoralists living in an arid climate in northern Kenya. The Gabra have recently experienced growth of milk marketing opportunities, and this change has caused a renegotiation of intrahousehold arrangements that affect households' location and migration decisions. We model three different outcomes of the household bargaining processes and test them empirically. Our results are consistent with a contested model of the household in which husbands locate households farther from towns in order to limit milk marketing opportunities.

Perceptions of Risk within Pastoralist Households in Northern Kenya and Southern Ethiopia
Provedor de dados: 31
Autores: Doss,   Cheryl R.; McPeak,   John G.; Barrett,   Christopher B.
Perceptions of risk may vary within households as well as across households and communities.  In this paper, we take advantage of panel survey data collected quarterly over a period of 2 ½ years to see how perceptions of risk vary across individuals over time. The surveyed households are in pastoralist communities in Northern Kenya and Southern Ethiopia and the survey period coincides with a severe drought in this region and the beginning of the recovery. We identify the structural heterogeneity of the perceptions of risk of these individuals.  Because of the nature of panel data, we can also test how the perceptions of risk are affected by shocks in previous periods.  In particular, we ask how an individual's risk perceptions change when shocks happen to...

ADOPTION OF MAIZE AND WHEAT TECHNOLOGIES IN EASTERN AFRICA: A SYNTHESIS OF THE FINDINGS OF 22 CASE STUDIES
Provedor de dados: 31
Autores: Doss,   Cheryl R.; Mwangi,   Wilfred; Verkuijl,   Hugo; De Groote,   Hugo.
This paper synthesizes the findings of 22 micro-level studies on technology adoption carried out by the International Maize and Wheat Improvement Center (CIMMYT) with national agricultural research systems in Ethiopia, Kenya, Tanzania, and Uganda from 1996-1999. The authors found that technology adoption is taking place across Eastern Africa but considerable scope remains to improve the productivity of smallholder agriculture in higher potential regions with high levels of adoption. Extension was the variable most highly correlated with technology adoption, and extension services continue to play an important role in disseminating information on new varieties and how to manage them. Despite the usefulness of the micro-study results, especially for priority...
