Measuring Competition Through Subsidies in Sierra Leone's Cocoa Market
In order to measure the level of competition among traders in Sierra Leone’s cocoa market, researchers conducted a randomized evaluation to test the impact of delivering subsidies to cocoa traders on prices that traders paid to cocoa farmers. While the bonus payments did not affect the prices paid to farmers, it did lead the traders to more frequently offer credit through advance payments to farmers. These results suggest that Sierra Leone’s agricultural trading sector was competitive, meaning that all traders offered similar prices to farmers.
