An interesting feature of Battalio et al.’s (1981) results is that taxing the highest wage pigeons in their experiment (by taking away a fraction of the food they earn) actually increases the amount of work the pigeons do. This contrasts with some economists’ claims that cutting taxes on high-earning workers will incentivize them to work harder. In your opinion, do Battalio et al.’s results have any relevance to human tax policy? Why or why not?
