Do-it-yourself activities are, by definition, those for which a choice must exist between doing it oneself or hiring someone else. This means they typically involve the own account production of services, but whereas it is customary to include most goods produced on own account in GDP services are conventionally excluded. In principle, however, it is possible to envisage a comprehensive and unique measure of the total final output of all the goods and services produced within an economy whether for sale or own use. Such a measure would be better than GDP as an indicator of long term changes in economic welfare, being independent of any shifts in the ratio of market to non-market production. Moreover, it would be a homogeneous measure with clearly defined limits in contrast to improvised indices of welfare which mix economic and non-economic variables in arbitrary and subjective ways. However, the need for a measure of market output, or something very close to it such as GDP, is still as strong as ever as soon as attention is switched from measurement of long term growth to problems associated with market disequilibria, such as unemployment and inflation. 相似文献

The effects of multicollinearity upon the risk improvement provided by Stein-like estimators over the maximum likelihood estimator in the normal regression model are investigated via Monte Carlo methods. Risk gains are found to degenerate rapidly given moderate degrees of multicollinearity. 相似文献

We present results from an artefactual field experiment conducted in rural Peru that considers whether observing non-reciprocal behavior influences an individual's decision to reciprocate. Specifically, we consider the behavior of second movers in a trust game, assessing whether their decision to reciprocate is influenced by the observed reciprocity of others. In documenting the impact of an external shock to observed reciprocity, this paper shows that small increases in non-reciprocal behavior result in an unraveling of the norm of reciprocity. Survey data is used to explore mechanisms by which this occurred. Results are not consistent with learning effects, suggesting that preferences may be changed by observing others deviating from a norm of reciprocity. These results suggest that investing in encouraging trustworthy behavior can have large benefits in situations where individuals are observing each other's behavior, such as may be the case in a new market institution. 相似文献

Process improvement programs such as Six Sigma, Lean, and Lean Sigma are very important and deserve serious academic research
attention. However, definition problems make it difficult to study any specific type of process improvement program. Therefore,
this study defines two organizational level program management factors, Strategic Project Selection (SPS) and Project Management
Infrastructure (PMI), that are independent of any specific process improvement program. Drawing upon current literature, this
study develops and tests theoretical models that relate SPS and PMI to operational performance improvement and to each other.
Using empirical data collected from 53 supplier plants of one large high-tech firm, this study finds that at the plant level,
SPS mediates the relationship between PMI and operational performance improvement. This insight contributes to both theory
development and practice, suggesting that a viable strategy for a process improvement program’s success is to focus on PMI
in order to enhance SPS and ultimately improve performance.
