We analyze self- and joint procurement of countries with heterogeneous demand for a good offered by a price discriminating monopolist. We find that not only countries with low but also with high demand can benefit from committing to jointly procure equal quantities at a uniform price, even if...

In US vaccine markets, competing producers with high fixed, sunk costs face relatively concentrated demand. The resulting price and quality competition leads to the exit of all but one or very few producers per vaccine. Our empirical analysis of exits from US vaccine markets supports the...
