This paper, provides some support for the latter approach by showing that it may be possible to analyze some relationships between socio-economic variables using web-based surveys consistently. In such cases cost-effective web-based surveys can be used to inform policy decisions in timely fashion. Using 10 years of Dutch data, we show that there exists an established segment of predominantly junior workers from which the respondents of the WageIndicator survey are disproportionally drawn. In consequence, the composition of WageIndicator sample tends to retain key characteristics over the years, even though it lacks a probabilistic sampling frame. We show that the estimates produced on the basis of an extended Mincerian earnings model using the two data sources are qualitatively similar. In line with much of the literature, however, the two sets of estimates do not pass the formal statistical test of equality. Nonetheless, when we examine only the subsample of junior workers, the statistical testing does not detect a statistically significant difference between the two datasets in many instances. To our knowledge, ours is the first paper showing such statistical evidence for comparability of a web survey based with a widely used representative data source.
