Using a microbased superpopulation approach (see Cassel and Lundquist (1991), (1990))the question of optimal predictors of a population total of AR(1) series is analysed. Only a sample of the individual timeseries in the population is observed. From the sample the population total is predicted....

An estimator of population parameters for cross sectional analysis is suggested. The estimator is basically the generalised regression estimator (TGR) but with an adjustment derived from optimal predictors of AR(1)-series. The P- properties of the estimator are studied and the efficiency of the...

This paper explains the internationalization process of small firms using the theory of performance relative to aspiration levels. The study complements prior theory by explaining why and how small firms are triggered to engage in internationalization despite not reaching maturity in their home...

This paper investigates the long-term survival and performance of new entrepreneurial firms, comparing firms located within regional clusters with those located outside of clusters.We use matched employee-employer databases to investigate all Swedish firms started in the telecom and consumer...

This paper investigates the role of knowledge in the evolution of new financial services ventures in Sweden between 1990 and 2002. Drawing upon economic theories of human capital and spin-out entrepreneurship, we investigate if knowledge from prior employment in the financial and technological...

The question of minimizing the bias due to the survey sampling error when estimating the autocorrelation function of aggregated AR(1) processes is studied.

Entrepreneurship is largely ignored or treated in a highly simplified way in endogenous growth theory. Still, it is now widely recognized that the supply of entrepreneurial talent is likely to be important for economic growth, innovation and job creation. In this study we provide an in-depth...

Using a microbased superpopulation approach some aspects of optimal prediction of aggregated AR(1) processes are studied.

We analyze the development of the Swedish ownership model after WWII. The controlling ownership in Swedish firms is typically concentrated to one or two owners. Often, but not always, the controlling owners are Swedish families. Thus, the model resembles the typical corporate control model of...

Analysts using data from official statistical authorities often neglect the fact that data frequently are collected using sample surveys. In this paper the impact of sampling error on the estimation of the autocovariance and the autocorrelation function is studied under a micro based...
