1. Markets and marketplaces : Essays on access and transformation in remote rural economies
- Abstract
Market access and agricultural intensification: Remotely-sensed evidence from Mozambican river crossings Many believe that high transport costs are a significant constraint to agricultural intensification in rural Africa. Empirical evidence is limited, however, because areas with high agricultural potential may see more infrastructure improvements and data is rarely available at the necessary granularity. We use satellite imagery to measure agricultural outcomes in Mozambique, where inadequate river crossings create discrete jumps in travel costs between banks. We find that better-connected banks have 4.1% more land under cultivation than worse-connected counterparts. Improved access thus leads to intensified land use, albeit at the potential cost of lost natural lands. Remotely-sensed market activity as a high-frequency economic indicator in remote rural areas Effective targeting of social policies and their rigorous evaluation require relevant and accurate data. With the majority of the world's poor depending on agriculture and informal businesses for their livelihoods, information on these sectors is particularly valuable. I use high-frequency satellite imagery to map rural marketplaces across large geographies and track activity within them in real-time. Measured activity not only displays intuitive variation with respect to exogenous shocks, but also deepens the temporal and geographical detail at which remote sensing-based analyses are possible. Rural marketplaces and local development Marketplaces are an age-old way to connect geographically separated producers and consumers, and they remain widespread in low-income countries. How do these gatherings shape development around them? To address long-standing data gaps, I combine historical sources with novel satellite-based methods to map marketplaces and measure local population density, establishing three stylized facts for Kenya over the last five decades. First, while rural population quadrupled, two third
