Virtually all models of the household assume that the allocation of resources is Pareto efficient. Within many African households, agricultural production occurs on many plots controlled by different members of the household. Pareto efficiency implies that factors should be allocated efficiently across these plots. I find, in contrast, that plots controlled by women are farmed much less intensively than similar plots within the household controlled by men. The estimates imply that about 6 percent of output is lost because of inefficient factor allocation within the household. The paper suggests a new approach to modeling intrahousehold allocation consistent with the empirical results.

Development economics has been the beneÞciary of a rich tradition of Þeld research. Within this broad tradition there is a huge variety of methods, from short qualitative studies in which the primary interaction between the researcher and the participants is relatively unstructured conversation to large-scale surveys designed by and perhaps loosely supervised by economists. In this note, however, I focus on one point in this broad space of research methodologies iterative Þeld research in which the collection of data through surveys is combined with detailed observation and conversation to elicit knowledge about institutions. A highly artiÞcial, but I hope useful typology is provided in Figure 1. Typically, empirical work in economics relies on existing data. However, it is becoming more common in development economics to complement existing data with relatively short, often less structured visits to the Þeld site in order to clarify aspects of the data, to better deÞne the economic environment, or to collect limited amounts of complementary data. For example, ICRISAT hosted and provided institutional support for a series of visiting scholars during the collection of the Village Level Surveys. This proved to be a relatively inexpensive mechanism that generated an important sequence of insights regarding economic institutions India (Rosenzweig (1998 EJ), Pender (1996) are examples of papers emerging from this

Countries? ” If there exist aggregate production functions representing approximately the same technology across countries, then the vastly higher output per worker in richer countries implies that capital per worker must be much higher in these countries, and diminishing returns implies a much lower rate of return to capital in rich than in poor countries. The details of the calculation depend, of course, on specific assumptions. However, the magnitudes are sufficiently large that the absence of massive capital flows to the poorest countries is properly seen as a fundamental puzzle. Lucas considers the possibility that capital market imperfections permit the existence of a gap in the returns to capital across countries, but argues that this cannot account for most of the difference implied by his calculation. He, therefore, raises the possibility that there are huge differences in human capital across countries, and externalities associated with these differences imply that returns to physical capital are not so different across countries with even large differences in physical capital per worker. Accordingly, there is no mystery about the lack of physical capital flows. In contrast, Abhijit V. Banerjee and Esther C. Duflo (2005) review a good deal of evidence, mostly from India, showing widely varying and often very high real interest rates.

We examine empirically the generalizability of internally valid micro-estimates of causal effects in a fixed population over time when that population is subject to aggregate shocks. Using panel data, we show that the returns to investments in agriculture in India and Ghana, small and medium non-farm enterprises in Sri Lanka, and schooling in Indonesia fluctuate significantly across time periods. We show how the returns to these investments interact with specific, measurable, and economically relevant aggregate shocks, focusing on rainfall and price fluctuations. We also obtain lower-bound estimates of confidence intervals of the returns based on estimates of the parameters of the distributions of rainfall shocks in our two agricultural samples. We find that even these lower-bound confidence intervals are substantially wider than those based solely on sampling error that are commonly provided in studies, most of which are based on single-year samples. We also find that cross-sectional variation in rainfall cannot be confidently used to replicate within-population rainfall variability. Based on our findings, we discuss methods for incorporating information on external shocks into evaluations of the returns to policy.

Insecure property rights over land have multiple ramifications for agriculture and the organization of rural economic activity (Besley and Ghatak 2009). The risk that land will be expropriated deters investment. Insecure property rights reduce the ability of borrowers to pledge land as collateral and thus tighten credit constraints. Ill-defined property right over land can inhibit land transactions – rentals or sales – and potential gains from trade are lost. Scarce resources, like labor, may be devoted to protecting one’s insecure rights over plots (Field 2007). In Ghana, land rights are typically gained by virtue of membership in a corporate group (e.g., extended family), but a robust market is emerging for land purchases and rentals, particularly in urban and periurban areas. Informal land markets in Ghana are beset with a number of problems including land conflicts, protracted litigation and adjudication failures, documentation bottlenecks and uncertainty. Land legislation in Ghana is perceived as incoherent, conflicting and often outdated. An unwieldy public land sector dominates the documentation of land rights, revenue collection and distribution. Land conflicts are becoming more frequent, judicial processes are overburdened, authority is overcentralized and corrupt. Conflict over multiple claims to particular plots occasionally becomes violent. Goldstein and Udry (2008) document the large investment disincentive effects of insecure tenure in agriculture in Ghana. Almost 80% of Ghana’s land is held by customary landowners, mainly families, clans and traditional authorities (Kasanga and Kotey, 2001). These owners often do not record transactions; indeed, many are clothed in secrecy. As land transactions gradually move away from their familial/corporate base to short term rental for commercial purposes, multiple simultaneous transactions on the same plot have be-

Standard measures of productivity display enormous dispersion across farms in Africa. Crop yields and input intensities appear to vary greatly, seemingly in conflict with a model of efficient allocation across farms. In this paper, we present a theoretical framework for distinguishing between measurement error, unobserved heterogeneity, and potential misallocation. Using rich panel data from farms in Tanzania and Uganda, we estimate our model using a flexible specification in which we allow for several kinds of measurement error and heterogeneity. We find that measurement error and heterogeneity together account for a large fraction of the dispersion in measured productivity.

We examine the impact of ambiguous and contested land rights on investment and productivity in agricultural in Akwapim, Ghana. We show that individuals who hold powerful positions in a local political hierarchy have more secure tenure rights, and that as a consequence they invest more in land fertility and have substantially higher output. The intensity of investments on different plots cultivated by a given individual correspond to that individual’s security of tenure over those specific plots, and in turn to the individual`s position in the political hierarchy relevant to those specific plots. We interpret these results in the context of a simple model of the political allocation of land rights in local matrilineages.

We look at the effects of rainfall forecasts and realized rainfall on equilibrium agricultural wages over the course of the agricultural production cycle. We show theoretically that a forecast of good weather can lower wages in the planting stage, by lowering ex ante out-migration, and can exacerbate the negative impact of adverse weather on harvest-stage wages. Using Indian household panel data describing early-season migration and district-level planting- and harvest-stage wages over the period 2005-2010, we find results consistent with the model, indicating that rainfall forecasts improve labor allocations on average but exacerbate wage volatility because they are imperfect.
