Françoise Carré and Chris Tilly emphasize the relationship between the low level of regularly scheduled work hours and low job quality in a new Upjohn Institute Policy Paper (and more detailed Working Paper). Focusing on U.S. workers in the retail sector, they compare hours and institutional environments with those in Canada and Mexico and show that institutional constraints lead retailers in the United States and Canada to reduce hours and expand part-time jobs, whereas in Mexico they lead to lengthening hours.
