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.

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.
Release date: 1994-11-16 - 3. Have Small Firms Created a Disproportionate Share of New Jobs in Canada? A Reassessment of the Facts ArchivedArticles and reports: 11F0019M1994071Geography: CanadaDescription:
The statistical observation that small firms have created the majority of new jobs during the 1980s has had a tremendous influence on public policy. Governmentshave looked to the small firm sector for employment growth, and have promoted policies to augment this expansion. However, recent research in the US suggeststhat net job creation in the small firm sector may have been overestimated, relative to that in large firms. This paper addresses various measurement issues raised inthe recent research, and uses a very unique Canadian longitudinal data set that encompasses all companies in the Canadian economy to reassess the issue of jobcreation by firm size. We conclude that over the 1978-92 period, for both the entire Canadian economy and the manufacturing sector, the growth rate of (net)employment decreases monotonically as the size of firm increases, no matter which method of sizing firms is used. The small firm sector has accounted for adisproportionate share of both gross job gains and job losses, and in that aggregate, accounted for a disproportionate share of the employment increase over theperiod. Measurement does matter, however, as the magnitude of the difference in the growth rates of small and large firms is very sensitive to the measurementapproaches used. The paper also produces results for various industrial sectors, asks whether the more rapid growth in industries with a high proportion of smallfirms is responsible for the findings at the all-economy level, and examines employment growth in existing small and large firms (ie excluding births). It is found thatemployment growth in the population of existing small and large firms is very similar.

The Random Group Method for sampling with probability proportional to size (PPS) is extended to sampling over two occasions. Information on a study variate observed on the first occasion is used to select the matched portion of the sample on the second occasion. Two real data sets are considered for numerical illustration and for comparison with other existing methods.
