*Do fertility plans influence marriage? Children can be part of the marital capital that individuals seek to maximise when they marry. We use variations in policy implementation of the One-Child Policy in China and its relaxation to capture the effect of the possible number of children on marriage. We find that men who benefit more from the relaxation as they gain the right to have a second child are more likely to get married after the end of the One-Child Policy. We argue that this is because due to a skewed sex ratio, some men are unable to find a spouse. When given a choice, women choose the spouse who can bring them the most children. The effect is concentrated among less educated men. Investigating the effect on who marries whom, we find that while treated men are more likely to get married they marry less educated women.

**In pursuit of food security, several governments in Sub-Saharan Africa (SSA) have recently turned to policies that stimulate the domestic production of a critical agricultural input – mineral fertiliser – while simultaneously raising trade barriers that discourage imports of these inputs. Yet it is unclear whether such import substitution policies achieve their intended goal of expanding access to fertilisers because of the presence of domestic trade frictions that separate farms from markets. With internal trading frictions, reductions of production costs at the factory gate may not automatically translate to increased adoption rates and improved crop yields among smallholder farms in remote regions. To shed light on these effects, this paper examines an industrial policy in Nigeria that led to the entry of 22 large-scale fertiliser manufacturing and processing facilities between 2015 and 2019. Using household panel surveys and geocoded data on plant locations, I measure the regional effects of plant entry on patterns of fertiliser retail prices, adoption rates, and crop yields. I take advantage of the fact that farm-households were differentially exposed to plant entry based on the transport costs they face, as well as regional variation in the geological conditions that permit fertiliser production. Preliminary findings suggest that farms further away from factories face higher retail prices, use less fertiliser and have lower crop yields. To rationalise these findings, I intend to develop a quantitative model of economic geography that takes into account input choices and the spatial heterogeneity of smallholder agriculture.
