The economics and politics of women's rights

Women’s rights and economic development are highly correlated. Today, the discrepancy between the legal rights of women and men is much larger in developing compared to developed countries. Historically, even in countries that are now rich women had few rights before economic development took off. Is development the cause of expanding women’s rights, or conversely, do women’s rights facilitate development? We argue that there is truth to both hypotheses. The literature on the economic consequences of women’s rights documents that more rights for women lead to more spending on health and children, which should benefit development. The politicaleconomy literature on the evolution of women’s rights finds that technological change increased the costs of patriarchy for men, and thus contributed to expanding women’s rights. Combining these perspectives, we discuss the theory of Doepke and Tertilt (2009), where an increase in the return to human capital induces men to vote for women’s rights, which in turn promotes growth in human capital and income per capita

IL-22 Is Produced by Innate Lymphoid Cells and Limits Inflammation in Allergic Airway Disease

Interleukin (IL)-22 is an effector cytokine, which acts primarily on epithelial cells in the skin, gut, liver and lung. Both pro- and anti-inflammatory properties have been reported for IL-22 depending on the tissue and disease model. In a murine model of allergic airway inflammation, we found that IL-22 is predominantly produced by innate lymphoid cells in the inflamed lungs, rather than TH cells. To determine the impact of IL-22 on airway inflammation, we used allergen-sensitized IL-22-deficient mice and found that they suffer from significantly higher airway hyperreactivity upon airway challenge. IL-22-deficiency led to increased eosinophil infiltration lymphocyte invasion and production of CCL17 (TARC), IL-5 and IL-13 in the lung. Mice treated with IL-22 before antigen challenge displayed reduced expression of CCL17 and IL-13 and significant amelioration of airway constriction and inflammation. We conclude that innate IL-22 limits airway inflammation, tissue damage and clinical decline in allergic lung disease

The lion’s share. An experimental analysis of polygamy in Northern Nigeria

Using samples of polygamous and non-polygamous households from villages in rural areas south of Kano, Northern Nigeria we test basic theories of household behaviour. Husbands and wives play two variants of a voluntary contributions game in which endowments are private knowledge, but contributions are public. In one variant, the common pool is split equally. In the other treatment the husband allocates the pool (and wives are forewarned of this). Most partners keep back at least half of their endowment from the common pool, but we find no evidence that polygynous households are less efficient than their monogamous counterparts. We also reject a strong form of Bergstrom’s model of polygyny in which all wives receive an equal allocation. In our case, senior wives often receive more from their husbands, no matter what their contribution. Thus the return to contributions is higher for senior wives compared to their junior counterparts. When they control the allocation, polygynous men receive a higher payoff than their monogamous counterparts. We speculate on the implications of this pattern of investment and reward for the sustainability of polygynous institutions
