    Description:

    Non-response in longitudinal studies is addressed by assessing the accuracy of response propensity models constructed to discriminate between and predict different types of non-response. Particular attention is paid to summary measures derived from receiver operating characteristic (ROC) curves and logit rank plots. The ideas are applied to data from the UK Millennium Cohort Study. The results suggest that the ability to discriminate between and predict non-respondents is not high. Weights generated from the response propensity models lead to only small adjustments in employment transitions. Conclusions are drawn in terms of the potential of interventions to prevent non-response.

    Description:

    This paper develops two Bayesian methods for inference about finite population quantiles of continuous survey variables from unequal probability sampling. The first method estimates cumulative distribution functions of the continuous survey variable by fitting a number of probit penalized spline regression models on the inclusion probabilities. The finite population quantiles are then obtained by inverting the estimated distribution function. This method is quite computationally demanding. The second method predicts non-sampled values by assuming a smoothly-varying relationship between the continuous survey variable and the probability of inclusion, by modeling both the mean function and the variance function using splines. The two Bayesian spline-model-based estimators yield a desirable balance between robustness and efficiency. Simulation studies show that both methods yield smaller root mean squared errors than the sample-weighted estimator and the ratio and difference estimators described by Rao, Kovar, and Mantel (RKM 1990), and are more robust to model misspecification than the regression through the origin model-based estimator described in Chambers and Dunstan (1986). When the sample size is small, the 95% credible intervals of the two new methods have closer to nominal confidence coverage than the sample-weighted estimator.

    Geography: Canada
    Description:

    This paper adds to our understanding of the contributions made to the economy by small, medium-sized, and large businesses in Canada. It does this by examining the shares of gross domestic product (GDP) produced by each of these size groups in the business sector.

    Previous studies relied predominately on employment, an input to the production process, rather than on a measure of output. This study overcomes this problem by focusing directly on GDP.

    Description:

    This article uses the concept of expected working life, developed in a previous article, and expands it to include involuntary retirements based on certain scenarios. We also examine the effect of level of education on expected working life.

    Description:

    Based on data from the Infertility Component of the 2009/2010 Canadian Community Health Survey, this study estimated the prevalence of help-seeking among couples trying to get pregnant. The association between seeking help and the couples' socio-demographic characteristics was examined, as were the methods they used to try to achieve pregnancy.

    Description:

    This Economic Insights article presents new income data on Canadian households from the revised Canadian System of National Accounts (CSNA12). It is one of a series of Economic Insights articles designed to emphasize key aspects of the new national accounts data and their utility for analyses of the Canadian economy.

    The Canadian System of National Accounts had for many years combined the incomes and expenditures of non-profit institutions and certain other institutions with those of households. Over the years, this has led users to ask whether the economic picture of Canadian households would be similar if the data on non-profit institutions were no longer combined with the household data. One of the important changes with the current revisions is that data based on a "pure" measure of the household sector are now available.

    The new data, which provide more detail on the transactions of households with other sectors of the economy, tell fundamentally the same story as to the evolution and composition of household incomes and expenditures.
