| We hypothesize two sources for sheepskin effects signaling, and diplomas tied to jobs with downwards rigid wages. These theories have implications for diploma effects not only in the first, but also the second moments of the Mincerian earnings distribution that we are able to identify using a flexible econometric specification. Idiosyncrasies in Mexican labor market and educational institutions offer a natural experiment on which to train this methodology and test these theories. Correcting for heterogeneity in diplomas, we find no evidence of sheepskin effects, except on graduation from primary school. We find compelling evidence that returns to education (in both moments) are linked with labor market institutions and job-specific diplomas in the manner... |

| We develop a semi-structural price vector autoregression to capture coffee price dynamics over various time horizons. The presence of the International Coffee Agreement is permitted to alter supply responses to price signals through yield and planting effects. In the short run, the ICA caused Brazilian farm prices to become disconnected from international prices. In the long run, the ICA promoted supply response by providing a stable environment in which producers could use current price information to predict future prices. In the intermediate run, it muted supply response by necessitating an institutional price wedge between wholesale and farm level prices. In net, the ICA created a price cycle that does not exist in non-ICA periods. Oxfam's proposal to... |

| We develop a reduced-form model of price transmission in a vertical sector, allowing for refined asymetric, contemporaneous and lagged, own and cross price effects. The model is used to analyze wholesale-retail price dynamics in the US butter market. The analysis provides strong evidence of asymmetric price transmissions. It documents the complex nature of nonlinear price dynamics in a vertical sector and its implications for the distribution of future prices. It finds evidence that the asymmetric response to shocks is stronger in the sort run for retail prices, and in the longer run for wholesale prices. |
