Data Sparseness and Variance in Accounting Profitability

__Abstract__ A central question in strategic management is why some firms perform better than others. One approach to addressing this question empirically is to decompose the variance in firm-level profitability into firm, industry, location, and year components. Although it is well established that data sparseness in variance decomposition studies can lead to overestimating particular variance components, little attention has been paid to sample size requirements in strategic management studies that have examined the nature of differences in firm profitability. We conduct a meta-regression and variance decomposition study and conclude that the variatio

The Location of Markets, Perceived Entrepreneurial Risk, and Start-up Capital of Micro Rural Firms

It is argued that when founders of SMEs perceive the probability of a successful and lucrative venture to be greater, they are more likely to provide a greater proportion of the start-up capital. This paper provides an empirical examination of two concurrent hypotheses. Firstly, that the size of the debt or equity is affected by factors influencing perceived entrepreneurial risk. Secondly, that the location of the market for the firm’s output is a major factor reducing perceived entrepreneurial risk and increasing equity of the start-up capital. A statistical analysis based on the simultaneous tobit model is used. Results show that significant factors influencing risk perception include the size of the new business and the sector of economic activity, as well as entrepreneurial experience and the location of the markets for the firm’s output. The results highlight implications for the design and implementation of rural development policies and especially for the instruments supporting rural business creation. Copyright Springer 2005
