JOB AMENITY AND THE INCIDENCE OF DOUBLE WORK

The hypothesis that workers in jobs associated with an amenity are mor e prone to moonlighting is derived and tested. If earnings fall for su ch jobs, it is rational to have two jobs while for jobs with no amenit y a fall in earnings causes a rational worker to leave the sector alto gether. An amenity can be expected for instance for workers in primary sectors and evidence that farmers at an increasing rate have double o ccupations are provided. The comparative statics on the models shows, among other things, that wage increases outside the amenity sector may have different effects than wage decreases inside the sector. The mod els are tested on data on farmers and to some extent the regressions s upport the theoretical models.
