What This Case Teaches About Shock Incidence

Portugal’s community-pharmacy reforms answer the series’ central question in a qualified way: an industry shock can create two-tier wages instead of an immediate collapse in employment when the value of the sector falls, bargaining rules permit a cheaper path for new hires, and a continuing supply of occupation-specific workers keeps the workforce available. The result is not a painless alternative to layoffs. It is a different incidence pattern. The adjustment is shifted across cohorts and across time, with current employment preserved at the cost of lower pay for entrants and a possible decline in the profession’s future appeal.

The case is valuable because it connects outcomes that are often analyzed separately. Prescription-drug reforms reduced pharmacy margins. Value added per pharmacist fell. Collective bargaining changed the price and timing of experience. The average wage declined mainly as lower-paid cohorts became a larger share of the workforce. Employment nevertheless grew because entries and job changes outweighed exits. Later, pharmacy lost ground relative to nursing and medicine, and the academic standing of applicants and enrollees declined even though the graduate inflow remained above replacement. Taken together, these are not disconnected facts. They are stages in one process of shock incidence.

The full chain: from margin compression to cohort wages

The upstream condition was a common reduction in the value created by retail pharmacies. Portugal’s regulated system constrained wholesale prices and dispensing markups, and reforms during 2010–2014 also encouraged generic substitution and changed reference-price and patent-expiry rules. The average margin per filled prescription fell from €2.14 in 2010 to €1.24 in 2014, a 42 percent nominal reduction. The study reports a roughly 48 percent reduction in the price component of real value added after consumer-price changes, while its broader measures show value added per pharmacist falling by about one-third during the central reform period.

Those numbers define the pressure facing the sector, but they do not yet identify who paid. A smaller margin can be absorbed through lower profits, reduced employment, altered staffing, lower wages, or a combination. The fact that the service remained necessary does not guarantee that the old price of pharmacist labor could be maintained. Pharmacies still needed qualified workers to operate, but the value available to distribute across workers and owners was lower.

The bargaining system supplied the next link. Most pharmacists were covered by a sectoral agreement that set experience-based wage floors. Actual pay also included cushions above those floors and various premiums or supplements. Before the crisis-era changes, pharmacists generally progressed through the ordinary floor sequence after about a year at each level. The 2010 agreement relabeled categories and changed the treatment of additional hours; the authors also find evidence of some reshuffling into lower categories. These changes created room for adjustment without requiring one identical percentage cut for every established worker.

The 2012 agreement made the distributional channel explicit. New hires were placed on a lower schedule with a new entry level, floors about 10 percent below the main tier, and an entry floor about 24–25 percent below the earlier entry floor. Promotion slowed from one year per level before 2012 to two years and then longer periods in later agreements. Some incumbents could move to the lower schedule in exchange for extra holidays. The design therefore changed both the starting price of labor and the time required for experience to produce higher pay.

That is why two-tier bargaining matters as an incidence mechanism. It did not simply record that new hires happened to earn less. It established a rule under which a common loss in sector value could be assigned more heavily to people entering after a cutoff. An incumbent could experience inflation and category reshuffling while remaining closer to the older schedule. A new pharmacist could start lower, spend longer at each level, and receive a smaller cushion. The wage system translated a sector-wide shock into a difference between career paths.

The next link was composition. By 2018, more than 60 percent of pharmacists in the study were covered by the lower-tier arrangements. As new graduates entered and workers changed employers, the lower-paid group became a larger share of the population whose average wage was being calculated. The average could therefore fall for two reasons at once: some workers lost real pay within their group, and the workforce contained more people on the lower path.

The study’s decomposition shows how important that second channel was.
