This article analyzes important changes in technological innovation in the upstream petroleum industry. It provides evidence that shifts in sectoral patterns of innovation over the petroleum industry's lifecycle from the 1970s up to 2005 were dependent on the dynamics of knowledge base complexity (KBC), a key dimension of an industry's technological regime. Accordingly, observed shifts in innovation patterns are understood to be the aggregated strategic response of industry innovators to changes in the technological regime. The article proposes a quantitative method for exploring KBC and Schumpeterian patterns of innovation, and interactions between the two at the industry level. As the industry evolved, its knowledge base moved to higher orders of complexity creating a shift in the Schumpeterian pattern of innovation. Increased KBC was found to alter Schumpeterian patterns from Mark I toward a ‘modified’ Mark II. Instead of coming predominantly from ‘traditional’ established oil operators, technological innovation was increasingly triggered by a new class of emergent integrated service companies – ‘second tier’ systems integrators of the upstream sector able to cope with increased KBC. 相似文献

Farmers’ motivations,risk perceptions and risk management strategies in a developing economy: Bangladesh experience 总被引:1,自引:0,他引:1
Dewan Ali Ahsan 《Journal of Risk Research》2013,16(3):325-349
Aquaculture farmers’ risk perceptions and risk management strategies have still received little attention in agricultural research. Therefore, an exploratory study has been undertaken to provide empirical insight into Bangladeshi coastal shrimp farmers’ risk perceptions and risk management responses. Data from our study show that 95% of farmers have no formal training in shrimp aquaculture. Shrimp farmers’ cooperative societies operate in only 13.3% of the studied areas and only 15% of shrimp farmers are involved with these cooperative societies. The results reveal that shrimp diseases, price and availability of quality shrimp seeds, exploitation by intermediaries and uncertainty about the future demand for shrimp in foreign markets are perceived as the most important sources of risk. On the other hand, prevention of disease, timely supply of shrimp seeds, elimination of middlemen from the supply chain and farm management training are considered among the best methods to manage the risks in the shrimp‐farming business. We also observe some disparities in farmers’ perceptions. For instance, farmers mentioned that removal of influence of middlemen from supply chain is essential for the betterment of their business. However, they did not consider market monitoring, direct contract with processors and improved marketing facilities as important risk management strategies, although these factors play a significant role in reducing the influence of intermediaries and private money lenders. 相似文献

This research paper aims to explore the role of FDI inflows and stock market development on the promotion of renewable energy consumption. Furthermore, study investigates the effect of renewable energy consumption on CO2 emissions and economic output across a panel of Brazil, China, India, and South Africa. Study utilizes annual data from 1990 to 2012 and employs various robust panel econometric techniques. The findings confirm that both FDI inflows and stock market development play an important role in promoting renewable energy consumption. The results also reveal that renewable energy consumption helps to mitigate the growth of CO2 emissions and promotes economic development. 相似文献

This paper examines the behavior of the risk premium component of currency forward rates. Analyzing forward rates of one, two and three-month maturity, we find that the power of forward rate as a predictor of future spot rate decreases with the length of contract maturity. Further, we find that the proportion of the variance of the forward premium which is due to the variation of the risk premium is larger than the proportion due to the expected spot rate change for all currencies except for the Canadian dollar. This proportion also increases with the length of maturity. 相似文献

This study examines whether it is ever rational for analysts to post biased estimates and how information asymmetry and analyst experience factor into the decision. Using a construct where analysts wish to minimize their forecasting error, we model forecasted earnings when analysts combine private information with consensus estimates to determine the optimal forecast bias, i.e., the deviation from the consensus. We show that the analyst??s rational bias increases with information asymmetry, but is concavely related with experience. Novice analysts post estimates similar to the consensus but as they become more experienced and develop private information channels, their estimates become biased and deviated from the consensus. Highly seasoned analysts, who have superior analytical skills and valuable relationships, need not post biased forecasts. 相似文献

The aim of this study was to evaluate the attitude of Iranian auditors toward balance between auditing and marketing with respect to two important components of audit process such as business environment of auditing and corporate governance. The analysis is based on survey data from 257 respondents. To achieve the research aims, we specified four hypotheses based on social theories. The results of this study show that the auditors having positive attitude toward marketing and those who consider it as significant are able, to a large extent, balance spent time for inherent auditing tasks and marketing activities. In addition, the results show that an increase by a unit for the attitude toward business environment results in 0.489 unit increase in attitude toward balance of time spent on marketing and auditing activities, of which 0.396 is direct impact and 0.093 is indirect impact. 相似文献

Business continuity planning is an important element of business continuity management and is regarded as a fundamental step towards reducing the negative impacts of business disruptions caused by internal and external hazardous events. Many businesses are not prepared for such events, and very few studies have tried to examine and model the factors that contribute to business continuity management planning by various companies. In this paper we propose and develop a feed‐forward neural network for modelling businesses continuity planning by businesses based on a dataset of 283 businesses operating in the Greater Toronto Area in Ontario, Canada. The fully connected neural network applied was trained on 65 % of the dataset records using different subsets of input variables. In order to preserve the generalization ability of the trained network, 15 % of the dataset records were used as a validation set for early stopping during the network's training process. Prediction capability of the trained networks was evaluated on 20 % and never‐seen records of the dataset. The classification ability of the networks was then analysed using receiver operating characteristic and detection error trade‐off curves, where the results obtained were promising. The equal error rate for the best models was 12 %, which reflects a very good accuracy of these models in predicting the existence of business continuity planning for a generic company.

Several twin crises occurred in the Turkish economy in the last three decades. In this article, we aim to analyze the link between banking and currency crises and to illustrate the essential determinants of these twin crises by developing a multivariate logit model for the period 1990–2013. The empirical findings show that Turkish currency crises are mainly due to excessive fiscal deficits, rises in short-term external debt, overvaluation of Turkish lira, and external adverse shocks; banking crises are primarily caused by excessive money supplies and bank short positions. The empirical findings also indicate that banking crises lead to currency crises, and vice versa. 相似文献

The Growing Relationship Between China and Sub-Saharan Africa: Macroeconomic, Trade, Investment, and Aid Links 总被引:2,自引:0,他引:2
China's economic ascendance over the past two decades has generatedripple effects in the world economy. Its search for naturalresources to satisfy the demands of industrialization has ledit to Sub-Saharan Africa. Trade between China and Africa in2006 totaled more than $50 billion, with Chinese companies importingoil from Angola and Sudan, timber from Central Africa, and copperfrom Zambia. Demand from China has contributed to an upwardswing in prices, particularly for oil and metals from Africa,and has given a boost to real GDP in Sub-Saharan Africa. Chineseaid and investment in infrastructure are bringing desperatelyneeded capital to the continent. At the same time, however,strong Chinese demand for oil is contributing to an increasein the import bill for many oil-importing Sub-Saharan Africancountries, and its exports of low-cost textiles, while benefitingAfrican consumers, is threatening to displace local production.China poses a challenge to good governance and macroeconomicmanagement in Africa because of the potential Dutch diseaseimplications of commodity booms. China presents both an opportunityfor Africa to reduce its marginalization from the global economyand a challenge for it to effectively harness the influx ofresources to promote poverty-reducing economic development athome.
