Alpha's labour force is underemployed and Omega workers place a higher value on leisure than those in Alpha. more of Alpha's labour force is unemployed and Omega workers place a lower value on leisure than those in Alpha. more of Omega's labour force is unemployed or Omega workers place a lower value on leisure than those in Alpha
