This article presents first-hand evidence about land distribution and the impact of land markets in central Uganda. This area is characterized by unequal distribution of land inheritance, rural-rural migration, and active land markets. We show that land markets, and particularly land purchases, tend to reduce the initial inequality in the initial (inherited) distribution of land. Land purchases by landless farmers in their native village represent an important part of this adjustment.

In the context of growing societal demands for land-based products, crop production can be increased through expanding cropland or intensifying production on cultivated land. Intensification can allow sparing land for nature, but it can also drive further expansion of cropland, i.e. a rebound effect. Conversely, constraints on cropland expansion may induce intensification. We tested these hypotheses by investigating the bidirectional relationships between changes in cropland area and intensity, using a global cross-country panel dataset over 55 years, from 1961 to 2016. We used a cointegration approach with additional tests to disentangle long- and short-run causal relations between variables, and total factor productivity and yields as two measures of intensification. Over the long run we found support for the induced intensification thesis for low-income countries. In the short run, intensification resulted in a rebound effect in middle-income countries, which include many key agricultural producers strongly competitive in global agricultural commodity markets. This rebound effect manifested for commodities with high price-elasticity of demand, including rubber, flex crops (sugarcane, oil palm and soybean), and tropical fruits. Over the long run, strong rebound effects remained for key commodities such as flex crops and rubber. The intensification of staple cereals such as wheat and rice resulted in significant land sparing. Intensification in low-income countries, driven by increases in total factor productivity, was associated with a stronger rebound effect than yields increases. Agglomeration economies may drive yield increases for key tropical commodity crops. Our study design enables the analysis of other complex long- and short-run causal dynamics in land and social-ecological systems.

This article proposes an original theory of marriage payments based on insights gained from firsthand information collected in the Senegal River valley. This theory postulates that decisions about the bride-price, which are made by the bride's father, take into account the likely effects of the amount set on the risk of ill-treatment of the wife and the risk of marriage failure. Based on a sequential game with three players (the bride's father, the husband, and the wife) and a matching process, it leads to a number of important predictions that are tested against Senegalese data relating to bride-prices and various characteristics of women. The empirical results confirm that parents behave strategically by keeping bride-prices down so as to reduce the risk of marriage failure for their daughters. Other interesting effects on marriage payments and the probability of separation are also highlighted, stressing the role of the bride's bargaining power in her own family.
