    Content: This paper investigates the reasons for the low application of external fertilizers on farms in Kenya and Uganda. The analysis uses a large panel of household data with rich soil fertility data at the plot level. The authors control for maize seed selection and household effects by using a fixed-effects semi-parametric endogenous switching model. The results suggest that Kenyan maize farmers have applied inorganic fertilizer at the optimal level, corresponding to the high nitrogen-maize relative price, in one of the two survey years and also responded to the price change over time. In Uganda, even the low application of inorganic fertilizer is not profitable because of its high relative price. The authors conclude that policies that reduce the relative price of fertilizer could be effective in both countries, while the efficacy of policies based on improving farmers' knowledge about fertilizer use will be limited as long as the relative price of fertilizer remains high

    Content: In Africa, most development strategies include efforts to improve the productivity of staple crops grown on smallholder farms. An underlying premise is that small farms are productive in the African context and that smallholders do not forgo economies of scale-a premise supported by the often observed phenomenon that staple cereal yields decline as the scale of production increases. This paper explores a research design conundrum that encourages researchers who study the relationship between productivity and scale to use surveys with a narrow geographic reach, when policy would be better served with studies based on wide and heterogeneous settings. Using a model of endogenous technology choice, the authors explore the relationship between maize yields and scale using alternative data. Since rich descriptions of the decision environments that farmers face are needed to identify the applied technologies that generate the data, improvements in the location specificity of the data should reduce the likelihood of identification errors and biased estimates. However, the analysis finds that the inverse productivity hypothesis holds up well across a broad platform of data, despite obvious shortcomings with some components. It also finds surprising consistency in the estimated scale elasticities

    Series Statement: Background Paper for the World Development Report 2013
    Content: This paper reviews the relative importance of different components of rural labor markets, examining how their functions differ across geographical locations and change over time, and inquiring into the difference in the contribution to poverty reduction among different jobs (i.e., agricultural wage employment, formal and informal nonfarm wage jobs, and nonfarm self-employment). Improving rural investment climate through investment in infrastructure and provision of credit will be helpful, because in all likelihood, increased access to nonfarm jobs, in general, and formal jobs in particular, will become a key factor affecting the improvement of living standards and poverty reduction in Sub-Saharan Africa (SSA), a phenomenon particularly visible in Asia from the mid-1980s to late-2000s which has started to appear in Africa. The development of agriculture stimulates the growth of nonfarm sectors through production and consumption linkages. Furthermore, increased farm income tends to be invested in schooling of children, who later look for nonfarm jobs, as seen in the Asian experience. Supply of such educated labor force to nonfarm sectors must have contributed to their development, and balanced development strategy for both farm and nonfarm sectors is clearly needed in SSA for achieving the twin goals of improving living standards and reducing rural poverty.

An underlying premise is that small farms are productive in the African context and that smallholders do not forgo economies of scale—a premise supported by the often observed phenomenon that staple cereal yields decline as the scale of production increases. This article explores a research design conundrum that encourages researchers who study the relationship between productivity and scale to use surveys with a narrow geographic reach in order to produce more reliable results, even though results are better suited for policy decisions when they are based on data that are broadly representative. Using a model of endogenous technology choice, we explore the relationship between maize yields and scale using alternative data. Since rich descriptions of the decision environments that farmers face are needed to identify the applied technologies that generate the data, improvements in the location specificity of the data should reduce the likelihood of identification errors and biased estimates. However, our analysis finds that the inverse-productivity hypothesis holds up well across a broad platform of data, despite obvious shortcomings with some components. It also finds surprising consistency in the estimated scale elasticities.
