This essay and the following commentaries address the use of theory in operations management. While much is said about theory in the typical journal article, theory, as science defines it, is not at the center of much of our research. The discipline had fallen into some bad habits. This essay and its commentaries appeal for more attention to what theory can mean for our understanding of operations management.  相似文献

We study repeated water allocation decisions among small scale irrigation users in Tanzania. In a treatment replicating water scarcity conditions, convexities in production make that substantial efficiency gains can be obtained by deviating from equal sharing, leading to an equity–efficiency trade‐off. In a repeated game setting, it becomes possible to reconcile efficiency with equity by rotating the person who receives the largest share, but such a strategy requires a longer run perspective. Correlating experimental data from an irrigation game with individual time preference data, we find that less patient irrigators are less likely to use a rotation strategy.  相似文献

Stochastic integer programming is more complicated than stochastic linear programming, as will be explained for the case of the two-stage stochastic programming model. A survey of the results accomplished in this recent field of research is given.  相似文献

Do unfettered markets produce too many or too few entrepreneurs? Two seminal papers [ Stiglitz and Weiss (1981) and de Meza and Webb (1987) ] obtained ambiguous answers to this question based on different assumptions about the character of information asymmetries in credit markets. The present paper approaches the same question but using a labor market model in which income is determined by ability and individuals derive utility from income and occupational group status. Occupational group status for entrepreneurs depends on the average entrepreneurial income (due to ex post screening by banks), whereas status for wage employees depends on their own income and ability (due to ex ante screening by employers). Thus, individuals create externalities through their occupational choice. It is shown that there can be too many or too few entrepreneurs in equilibrium depending on the marginal returns to ability in entrepreneurship relative to paid employment; this enables the researcher to use independent evidence about occupational marginal returns to identify the relevant equilibrium likely to arise in practice, together with the likely appropriate policy responses. Based on this approach, we suggest that there may be too many (low ability) entrepreneurs in the USA.  相似文献

Based on the examination of 239 “best products” (all those on Business Week's annual lists from the past decade), this article tests and validates a conceptual framework identifying six ways in which new products open new markets and/or encroach on original products. Three of these six scenarios involve high‐end encroachment (the new product first opens a new high‐end market, or enters at the high end of an existing market, and then diffuses down‐market), and three scenarios involve low‐end encroachment (encroachment starts at the low end, followed by diffusion up‐market). As illustrated in a 2 × 3 matrix, high‐end encroachment ensues when the new product enhances performance with regard to the market's core attribute (low‐end encroachment ensues when this performance is diminished). The three high‐end sub‐types and three low‐end sub‐types are determined by the strength of performance along an ancillary attribute dimension. If the ancillary attribute performance is week, then the encroachment of the new product on the old market is immediate (corresponding to immediate high‐end encroachment and immediate low‐end encroachment, respectively). If the ancillary performance is moderate, then the new product expands the market at the high or low end (corresponding to new‐attribute high‐end encroachment and fringe‐market low‐end encroachment, respectively). If the ancillary performance is strong, then the new product first opens an entirely new market at the high or low end (corresponding to new‐market high‐end encroachment and detached‐market low‐end encroachment, respectively). The reliability and comprehensiveness of the encroachment framework is tested by asking a panel of eight judges to categorize each of the 239 products. Results show inter‐judge reliability of 98%, with all products falling within one of the six encroachment categories. Each of the encroachment types has unique implications on product positioning and pricing, as further discussed in the paper. Thus the model helps firms identify and analyze the various possible strategies that they might choose from when introducing new products.  相似文献

The present study examined employee‐involvement climate (i.e., information‐sharing and decision‐making climate) as a moderator of the relationship between pay‐level satisfaction and employee outcomes (i.e., job satisfaction, affective commitment, and turnover intention). Survey data were collected from 22,662 Belgian employees, representing 134 organizations. The hypotheses derived from distributive justice theory and from research on the meaning of pay received partial support. Multilevel analyses revealed that a decision‐making climate buffered the negative effects of low pay‐level satisfaction, and that an information‐sharing climate exacerbated the negative effects of low pay‐level satisfaction. Theoretical and practical implications of this differential moderating effect are discussed.  相似文献

Isolated single‐month, one‐off export transactions (observed once in a 49‐month window) turn out to be the dominant spell length in granular firm–product–destination trade data. Moreover, on average, for an export‐active firm, such one‐off events generate a significant part of foreign sales. These patterns cannot be explained by the lumpiness of trade (e.g., seasonal shipments), nor do they sit well with available trade models. To reconcile theory with the data, we introduce passive (i.e., unsolicited buyer‐side driven) exporting in addition to proactive exporting. Our empirical investigation establishes novel stylized facts on firm and destination characteristics associated with one‐off exporting.  相似文献

In this paper a corporate social responsibility audit is developed following the underlying methodology of the quality award/excellence models. Firstly the extent to which the quality awards already incorporate the development of social responsibility is examined by looking at the Malcolm Baldrige National Quality Award and the European Quality Award. It will be shown that the quality awards do not yet include ethical aspects in relation to social responsibility. Both a clear definition of social responsibility and an improved audit instrument are required. A definition and an audit instrument are developed which stimulate movement in that direction and help organisations to reflect on their position in relation to social responsibility.  相似文献
