Smallholder farm management under evolving land institutions
In Zambia, clearing land for cultivation is a reported mechanism for making land claims in contexts of uncertain rights and expropriation risk, and leaving land fallow is less common for those with weaker land rights. When only some farmers in a village obtain land title, the land security of untitled landholders, particularly women, can become less secure in contexts where there are fears that chiefs can reallocate land away from untitled smallh…
A Bayesian triple-hurdle model of maize market participation in Zambia
Smallholder participation in agricultural markets is vital for rural development, yet various constraints impede potential gains. We study the subject and make two contributions. First, we introduce a Bayesian triple-hurdle model as an alternative to the frequentist approach, providing researchers with a flexible approach. Second, we analyze determinants of market participation in Zambia, focusing on maize – a staple crop using a Bayesian triple-…
The impact of site-specific soil-test-based extension advice on farm management in Malawi
Does subsidizing legume seeds improve farm productivity and nutrition in Malawi
Disparate access to quality land and fertilizers explain Malawi’s gender yield gap
Nitrogen efficiency by soil quality and management regimes on Malawi farms
Maize is the primary economic and dietary staple crop for most poor farmers in Southern Africa, yet low yields have persisted in the region for decades. Intensifying maize production in a sustainable way using the same land will be increasingly important as virgin land becomes scarcer and fallowing becomes less common. This study investigates the sustainability of intensification underway in the African smallholder sector using a uniquely detaile…

Understanding fertilizer adoption and effectiveness on maize in Zambia
Increased fertilizer use will likely be crucial for raising and sustaining farm productivity in Africa, but adoption may be limited by ineffectiveness under certain conditions. This article quantifies the impacts of soil characteristics on maize response to fertilizer in Zambia using a nationally representative sample of 1453 fields, combining economic, farm management and soil analysis data. Depending on soil regimes, average maize yield respons…
The Quiet Rise of Large-Scale Trading Firms in East and Southern Africa
The share of smallholder-produced maize sold to large-scale traders (LSTs) has increased from virtually nil 10 years ago to 12 per cent and 37 per cent in Zambia and Kenya, respectively. We examine the causes and consequences of this transformation. LST investment has responded to growing market demand as well as to changes in farm structure and has been especially prominent in areas where medium-scale farms are concentrated. After controlling fo…
Female access to fertile land and other inputs in Zambia
Spatial equilibrium and price transmission between Southern African maize markets connected by informal trade
Pathways into and out of Poverty
This study identifies the factors associated with smallholder farm households that have risen out of poverty or descended into poverty between 1997 and 2007 in Kenya. The study uses data from a nationwide balanced panel of 1,275 households and data from detailed retrospective ‘life history’ survey of 84 households that had experienced either an appreciable improvement or decline in their asset wealth over the 10-year panel period. The results ind…
Facilitators and Challenges to Conducting Interdisciplinary Research
BACKGROUND: Complex, interconnected issues challenge the United States health care system and the patients and families it serves. System fragmentation, limited resources, rigid disciplinary boundaries, institutional culture, ineffective communication, and uncertainty surrounding health policy legislation are contributing to suboptimal care delivery and patient outcomes. METHODS: These problems are too complex to be solved by a single discipline.…
Fitting and Interpreting Cragg's Tobit Alternative using Stata
In this article, I introduce the user-written command craggit, which simultaneously fits both tiers of Cragg's (1971, Econometrica 39: 829–844) “two-tier” (sometimes called “two-stage” or “double-hurdle”) alternative to tobit for corner-solution models. A key limitation to the tobit model is that the probability of a positive value and the actual value, given that it is positive, are determined by the same underlying process (i.e., the same param…

The Short Form of the Geriatric Depression Scale
The Geriatric Depression Scale (GDS) exists in both short and long forms. The original 30-item form of the GDS has been shown to be an effective screening test for depression in a variety of settings. However, its utility in patients with demen tia of the Alzheimer type (DAT) is questionable. The short, 15-item version of the GDS was developed primarily for brev ity and, in particular, for use in populations such as the medically ill or those wit…
