The purpose of this paper is to examine ways to improve ergonomics on the manufacturing shop floor. In particular, the impact of certain ergonomic practices on companies' economic and social objectives is investigated empirically. In order to do so, a survey has been conducted among manufacturing managers of 55 companies in the German automotive industry. The managers have been asked about their estimations on harmful tasks within the production process and on the effectiveness of various practices in the context of ergonomics and health. Worker-oriented and work-oriented practices of ergonomics are operationalized using factor analysis. By means of a cluster analysis, companies with a high degree of implementation of ergonomic practices are identified. The analysis shows that plants with a higher implementation degree of ergonomic practices show a better performance in terms of economic and social objectives. Furthermore, the results reveal that work-oriented practices lead to better performance with respect to the investigated economic and social objectives, whereas worker-oriented practices play a supporting role only. Finally recommendations for manufacturing companies with regard to the field of ergonomics are derived from the empirical results. 相似文献

Tse (1998) proposes a model which combines the fractionally integrated GARCH formulation of Baillie, Bollerslev and Mikkelsen (1996) with the asymmetric power ARCH specification of Ding, Granger and Engle (1993). This paper analyzes the applicability of a multivariate constant conditional correlation version of the model to national stock market returns for eight countries. We find this multivariate specification to be generally applicable once power, leverage and long-memory effects are taken into consideration. In addition, we find that both the optimal fractional differencing parameter and power transformation are remarkably similar across countries. Out-of-sample evidence for the superior forecasting ability of the multivariate FIAPARCH framework is provided in terms of forecast error statistics and tests for equal forecast accuracy of the various models. 相似文献

This paper explores the role of exchange rate regimes in explaining deviations from the classic theory of purchasing power parity. Examining a broad panel of countries, I find that developing countries with fixed exchange rate regimes have national price levels that are 20 percent higher than those with flexible regimes. For industrial countries, the relation between regimes and price levels is qualitatively similar but weaker. I investigate several explanations for this pattern, and find that exchange-rate overshooting in floats, inflation inertia in pegs and expansionary policies can explain only 5 percentage points of the observed differences. I also show that even though the observed pattern could be the outcome of a class of open economy models pioneered by Obstfeld and Rogoff, the data provides limited empirical support for the predictions of this model. 相似文献

Peer Group Formation in an Adverse Selection Model 总被引:1,自引:0,他引:1

This paper develops an adverse selection model where peer group systems are shown to trigger lower interest rates and remove credit rationing in the case where borrowers are uninformed about their potential partners and ex post state verification (or auditing) by banks is costly. Peer group formation reduces interest rates due to a 'collateral effect', namely, cross subsidisation amongst borrowers acts as collateral behind a loan. By uncovering such a collateral effect, this paper shows that peer group systems can be viewed as an effective risk pooling mechanism, and thus enhance efficiency, not just in the full information set up. 相似文献
