Prior research mentions that there may be technology assimilation gaps in that a technology may be cumulatively assimilated over a period of time depending on knowledge and experience from initial usage. Thus, stages of partial assimilation are indicated that, if not accounted for, could lead to erroneous understanding of technology adoption and diffusion. However, the phenomenon has not received serious academic attention, and there is still a lack of understanding as to when and why partial assimilation may occur, its consequences to organizations, and remedial steps that could be taken to minimize it. We investigate these issues in the context of assimilation of third-party business-to-business (B2B) e-market by four small firms. Our findings reveal that partial assimilation occurred because of different perceptions of benefit and risk of the two different features of the B2B e-market—the informational (buyer/supplier and product information) and the transactional (auction, request for quote, price negotiation, message archiving, payment systems), arising from different moderating impacts of the organizational (relational norms and the type of business handled) and environmental (perceptions of competitive pressure and institutional norms of technology usage and work practices) contexts of deployment and usage of the two features. The consequences of partial assimilation were mixed; while it was found to be detrimental to firms with low relational norms with their clients, it proved to be gainful for firms with high relational norms. Theoretical and practical implications of the findings are discussed.  相似文献

Technologies can be not only contentious—overthrowing existing ways of doing things—but also morally contentious—forcing deep reflection on personal values and societal norms. This article investigates that what may impede the acceptance of a technology and/or the development of the field that supports or exploits it, the lines between which often become blurred in the face of morally contentious content. Using a unique dataset with historically important timing—the United States Biotechnology Study fielded just 9 months after the public announcement of the successful cloning of the first mammal (i.e., Dolly the sheep)—we find that microlevel factors (i.e., conservative Christianity) predict unfavorable judgments of the technology-field intersection while macrolevel representations [i.e., exposure to Science, Technology, Engineering, and Mathematics disciplines and media coverage] predict more favorable judgments.  相似文献

Modern theories of inflation incorporate a vertical long-run Phillips curve and are usually estimated using techniques that ignore the non-stationary behaviour of inflation. Consequently, the estimates obtained are imprecise and unable to test the veracity of a vertical long-run Phillips curve. We estimate a Phillips curve model taking into account the non-stationary properties in inflation and identify a small but significant positive relationship between inflation and unemployment. The results also provide some evidence that the trade-off between inflation and the rate of unemployment in the short-run worsens as the mean rate of inflation increases.  相似文献

This study utilises the stock market data provided by the Australian Equity Database to analyse the long-run relationship between Australian stock returns and key macroeconomic variables over the period 1926–2017. To measure the diverse risk factors in the stock market, we examine the possible determinants in four main categories: real, financial, domestic and international. Our results reveal that historical stock returns are strongly connected to financial and international factors as compared to real and domestic factors. Both the 1973–1974 OPEC Oil Price Crisis and 2007–2008 Global Financial Crisis had dampening effects on stock returns. There is a positive association between the US and Australian stock markets in the long-run. These findings on stock market dynamics and their linkages with domestic and international macroeconomic policy changes in the long-run have important implications for traders and practitioners.  相似文献

Agri-environmental schemes (AESs) are increasingly implemented to promote the adoption of environmentally friendly practices by farmers. We use a systematic review to explore the role of behavioural factors and opportunity costs in farmers' decisions to participate in AESs in Australia, Europe and North America. Behavioural factors influence how farmers value and perceive options, while opportunity costs relate to farmers' forgone utility when choosing to participate in schemes. We synthesise insights from 79 articles and over 700 factors explaining the participation in AESs. We find that a set of behavioural factors seem consistently connected to participation, including agricultural training, advice and having positive attitudes towards AESs. Moreover, several factors related to opportunity costs also have a rather consistent relationship with AES participation, including market conditions, implementation efforts, profitability, and management and contract flexibility. However, many relationships of behavioural factors and opportunity costs with AES participation are not as consistent and generalizable as sometimes portrayed and require context-specific interpretation. Those factors with mixed results can still provide insights into farmers' participation decisions as several of them are either ‘positively and insignificantly’ or ‘negatively and insignificantly’ related to participation, such as environmental attitude, trust and farm size. These results suggest that their relationship with AES participation depends on other factors or the setting, highlighting interactions and raising important new research questions. Overall, our results provide several entry points for both researchers and policy-makers, highlighting uncertainties in relationships between factors and participation that should be considered when designing policies.  相似文献

Algorithmic traders use their advantage of speed to execute a large number of small-sized trades in a very short time. In the presence of a minimum trading unit (MTU) restriction, they are forced to trade at the smallest possible sizes, often restricted by the MTU. Using a novel data set of single stock futures market obtained from the National Stock Exchange of India, we show that the MTU restriction acts as a binding constraint for traders while optimizing trade sizes. Contrary to expectation, we find weak evidence that liquidity is positively impacted by the contract size revision.  相似文献

The authors present a semester-long game to teach the role of economics in natural resources management. The game is framed within a fisheries context: multiple student fisheries harvest fish to maximize yield/profit, which is measured using a piecewise linear function. There are prizes for both the student and the group with the highest semester-long catch, which brings forth the social dilemma associated with dynamic stock externalities in fisheries. The game can be played in large classes, is robust to student attrition, and requires 5–10?minutes per class period. Given its features, it can be used to teach behavioral economic principles in resource management, incentives versus command-and-control regulations, role of cheap talk, social preferences, punishment, and community management as well as solutions such as aquaculture.  相似文献

This paper examines the important determinants of the decision to remit and of the amount remitted by migrants in Delhi to their place of origin. The findings are compared with those obtained for Kenya by Knowles and Anker. The comparative exercise helps us to identify universal patterns of remittance behaviour from those which are time, place and sample specific. The paper also throws light on the validity of infering technological change in agriculture in rural areas from data on uses of remittances.  相似文献

Past studies on laboratory corruption games have not been able to find consistent evidence that subjects make “immoral” decisions. A possible reason, and also a critique of laboratory corruption games, is that the experiment may fail to trigger the intended immorality frame in the minds of the participants, leading many to question the very raison d’être of laboratory corruption games. To test this idea, we compare behavior in a harassment bribery game with a strategically identical but neutrally framed ultimatum game. The results show that fewer people, both as briber and bribee, engage in corruption in the bribery frame than in the alternative and the average bribe amount is lesser in the former than in the latter. These suggest that moral costs are indeed at work. A third treatment, which relabels the bribery game in neutral language, indicates that the observed treatment effect arises not from the neutral language of the ultimatum game but from a change in the sense of entitlement between the bribery and ultimatum game frames. To provide further support that the bribery game does measure moral costs, we elicit the shared perceptions of appropriateness of the actions or social norm, under the two frames. We show that the social norm governing the bribery game frame and ultimatum game frame are indeed different and that the perceived sense of social appropriateness plays a crucial role in determining the actual behavior in the two frames. Furthermore, merely relabelling the bribery game in neutral language makes no difference to the social appropriateness norm governing it. This indicates that, just as in the case of actual behavior, the observed difference in social appropriateness norm between bribery game and ultimatum game comes from the difference in entitlement too. Finally, we comment on the external validity of behavior in lab corruption games.  相似文献

In this paper, we extend the classical single period newsvendor model in an environment of customer balking, which occurs when customers are reluctant to buy a product if its available inventory falls below a threshold level. Since failure to make a sale usually results in a cost penalty, in addition to the opportunity cost of lost sales, we incorporate such costs in our model. Furthermore, we extend our model to include fixed ordering costs. Our analysis is based on the assumption that only the mean and the variance of the distribution of demand are known, without assuming any specific distributional form. We illustrate the concepts developed here through simple numerical examples and demonstrate the effectiveness of our approach by solving a set of 1000 randomly generated test problems.  相似文献
