Many recent descriptive studies find convex schooling-earnings profiles in developing countries. In these countries forward-looking students should attach option values to completing lower levels of schooling. Another option value may arise due to the uncertain economic environment in which the...

We play a one-shot public good game in rural India between farmers connected by an exogenous star network. Contributions by the centre of the star reach more players and have a larger impact on aggregate payoffs than contributions by the spoke players. Yet, we find that the centre player...

Standard models often predict that people should either demand to save or demand to borrow, but not both. We hypothesise instead that saving and borrowing among microfinance clients are substitutes, satisfying the same underlying demand: for a regular schedule of deposits and a lump-sum...
