    Description:

    We present a formal model based sampling solution to the problem of estimating list frame size based on capture-recapture sampling which has been widely used for animal populations and for adjusting the US census. For two incomplete lists it is easy to estimate total frame size using the Lincoln-Petersen estimator. This estimator is model based with a key assumption being independence of the two lists. Once an estimator of the population (frame) size has been obtained it is possible to obtain an estimator of a population total for some characteristic if a sample of units has that characteristic measured. A discussion of the properties of this estimator will be presented. An example where the establishments are fishing boats taking part in an ocean fishery off the Atlantic Coast of the United States is presented. Estimation of frame size and then population totals using a capture-recapture model is likely to have broad application in establishment surveys due to practicality and cost savings but possible biases due to assumption violations need to be considered.

    Description:

    This paper uses job turnover data to compare how job creation, job destruction and net job change differ for small and large establishments in the Canadian manufacturing sector. It uses several different techniques to correct for the regression-to-the-mean problem that, it has been suggested, might incorrectly lead to the conclusion that small establishments create a disproportionate number of new jobs. It finds that net job creation for smaller establishments is greater than that of large establishments after such changes are made. The paper also compares the importance of small and large establishments in the manufacturing sectors of Canada and the United States. The Canadian manufacturing sector is shown to have both a larger proportion of employment in smaller establishments but also to have a small establishment sector that is growing in importance relative to that of the United States.

    Description:

    A regression weight generation procedure is applied to the 1987-1988 Nationwide Food Consumption Survey of the U.S. Department of Agriculture. Regression estimation was used because of the large nonresponse in the survey. The regression weights are generalized least squares weights modified so that all weights are positive and so that large weights are smaller than the least squares weights. It is demonstrated that the regression estimator has the potential for large reductions in mean square error relative to the simple direct estimator in the presence of nonresponse.
