    A randomised controlled trial of email versus mailed invitation letter in a national longitudinal survey of physicians
    Harrap, B ; Taylor, T ; Russell, G ; Scott, A ; Alahdab, F (PUBLIC LIBRARY SCIENCE, 2023-08-22)
    Despite their low cost, the use of email invitations to distribute surveys to medical practitioners have been associated with lower response rates. This research compares the difference in response rates from using email approach plus online completion rather than a mailed invitation letter plus a choice of online or paper completion. A parallel randomised controlled trial was conducted during the 11th annual wave of the nationally representative Medicine in Australia: Balancing Employment and Life (MABEL) longitudinal survey of doctors. The control group was invited using a mailed paper letter (including a paper survey plus instructions to complete online) and three mailed paper reminders. The intervention group was approached in the same way apart from the second reminder when they were approached by email only. The primary outcome is the response rate and the statistical analysis was blinded. 18,247 doctors were randomly allocated to the control (9,125) or intervention group (9,127), with 9,108 and 9,107 included in the analysis. Using intention to treat analysis, the response rate in the intervention group was 35.92% compared to 37.59% in the control group, a difference of -1.66 percentage points (95% CI: -3.06 to -0.26). The difference was larger for General Practitioners (-2.76 percentage points, 95% CI: -4.65 to -0.87) compared to other specialists (-0.47 percentage points, 95% CI: -2.53 to 1.60). For those who supplied an email address, the average treatment effect on the treated was higher at -2.63 percentage points (95% CI: -4.50 to -0.75) for all physicians, -3.17 percentage points (95% CI: -5.83 to -0.53) for General Practitioners, and -2.1 percentage points (95% CI: -4.75 to 0.56) for other specialists. For qualified physicians, using email to invite participants to complete a survey leads to lower response rates compared to a mailed letter. Lower response rates need to be traded off with the lower costs of using email rather than mailed letters.

    Australia's superior skilled migration outcomes compared with Canada's
    Harrap, B ; Hawthorne, L ; Holland, M ; McDonald, JT ; Scott, A (WILEY, 2022-10-01)
    Abstract Australia and Canada are global exemplars of skilled migration policy, designed to have important effects on economic growth. This article assesses the development and outcomes of their permanent migration programmes for a range of regulated professions. We compare the matched census data from both countries in 2016 and then examine the key drivers of the major differences found through qualitative interviews. Although the trends in numbers and source countries and characteristics of skilled migrants are similar, their earnings relative to equivalent native‐born earnings are far lower in Canada than in Australia. This reflects the Australian government's greater power to initiate and drive policy reform agendas, early strategies designed to enhance foreign credential recognition and a heightened role for employers including through two‐step migration. Canada has recently announced significantly expanded migration intakes. These seem unlikely to lead to strong economic growth, unless entry requirements are tightened and more targeted support provided.
