The role of production technology for sustainable economic growth and resource management in the multispecies renewable resources industries is a neglected issue, particularly in complex tropical ecosystems. Given the still rudimentary understanding of biological interactions among species, even in most temperate ecosystems, the importance of under-standing the technological and economic interactions is heightened for sustainable economic growth and public regulation. This paper evaluates these interactions for the multiproduct gill net fisheries of Peninsular Malaysia. Standard price and quantity controls may have little promise. Gear regulations, a policy of constant escapement, and managing the entire mix of species as a single stock for economic rather than biomass yield appear the most promising management tools given the limited regulatory options. 相似文献

Here we consider the record data from the two-parameter of bathtub-shaped distribution. First, we develop simplified forms for the single moments, variances and covariance of records. These distributional properties are quite useful in obtaining the best linear unbiased estimators of the location and scale parameters which can be included in the model. The estimation of the unknown shape parameters and prediction of the future unobserved records based on some observed ones are discussed. Frequentist and Bayesian analyses are adopted for conducting the estimation and prediction problems. The likelihood method, moment based method, bootstrap methods as well as the Bayesian sampling techniques are applied for the inference problems. The point predictors and credible intervals of future record values based on an informative set of records can be developed. Monte Carlo simulations are performed to compare the so developed methods and one real data set is analyzed for illustrative purposes. 相似文献

In this article, a new numerical procedure is used to compute the equilibrium of a vintage capital growth model with nonlinear utility, where the scrapping time is nonconstant. We show that equilibrium investment and output converge nonmonotonically to the balanced growth path due to replacement echoes. We find that the average age of capital is inversely related to output, which is consistent with recent micro evidence reinforcing the importance of the embodied question. We also find that an unanticipated permanent increase in the rate of embodied technological progress causes labor productivity to slowdown in the short run. 相似文献

The present study sought to ascertain the perceptions of anti‐money laundering and counter‐financing of terrorism (AML/CFT) compliance officers of banks in Malaysia in order to develop an understanding of how well they understand the risks and how well they have implemented the obligations imposed by the regime. We examine these issues for the first time in the literature via the theory of crying wolf. A structured questionnaire survey of compliance officers of banks in Malaysia was followed by focus group discussions held at the Malaysian Institute of Bankers. We expect that the industry would consider suitable steps to improve the compliance culture, particularly in Islamic banks, and the regulators would watch such banks more diligently. Banks considered avoiding penalties, improving brand image and improving customer perceptions to be the rationale for implementing the AML/CFT legislation. Most conventional bank officers considered their organisations’ compliance culture to be high or very high, while this was not found to be the case in Islamic banks. 相似文献

It has been recently shown that rough volatility models, where the volatility is driven by a fractional Brownian motion with small Hurst parameter, provide very relevant dynamics in order to reproduce the behavior of both historical and implied volatilities. However, due to the non‐Markovian nature of the fractional Brownian motion, they raise new issues when it comes to derivatives pricing. Using an original link between nearly unstable Hawkes processes and fractional volatility models, we compute the characteristic function of the log‐price in rough Heston models. In the classical Heston model, the characteristic function is expressed in terms of the solution of a Riccati equation. Here, we show that rough Heston models exhibit quite a similar structure, the Riccati equation being replaced by a fractional Riccati equation. 相似文献

The use of Robotic Process Automation (RPA) is rapidly growing in the professional services sector such as auditing. Despite the great benefits RPA can offer, RPA failure rates are still high. In this research, we draw on socio-technical systems theory to examine the challenges of using RPA in the various phases of auditing and how auditors address these challenges. By interviewing experienced partners and auditors in auditing firms and technology companies, we show that challenges arise when there is a lack of fit between the technical requirements of the RPA tool (technical subsystem) and the skills and knowledge of the auditors and clients (social subsystem). We discuss our findings and provide valuable practical implications and opportunities for future research. 相似文献

Endogenous growth theory is based on a misperception of how science and technology are acquired and diffused. In particular, it is incorrect to assume that knowledge is freely available. Any knowledge which has economic value has to be accessed via the brains of experts who are members of the relevant 'invisible college' and are rivalrous.It therefore has the characteristics of a private good which can be left to conventional economic incentives to supply. 相似文献

Since acculturation is the process of acquiring the customs of an alternative society we assume that adapting to consumers from various cultures will be a fundamental task for African and Caribbean (A&C) companies in Britain. This study investigates market orientation of A&C service companies and their processes of cultural learning and adaptation using ethnicity as a basis for an exploratory study of the British market. The findings indicate that A&C companies serve as bicultural mediators, both accommodating their consumers and working to alter their consumption patterns to bring them into line with their own ethnic and British national market customs. The adaptation of A&C service companies to the cultural characteristics and needs of their customers results in changes to their companies, consumers and the British marketplace. 相似文献

This study compares the shopping habits for national and ownlabel brands to establish if there are differences in personal characteristics and purchase behaviour between those who buy national brands and those who buy own-labels in the UK. While statistical research could quantify how British grocery shoppers felt about food brands, it usually cannot explain why shoppers had the opinions they did, hence this study. It is thus an investigation, through the eyes of grocery shoppers, to answer the ‘WHY’ questions. Two distinct markets were found to exist. These grocery shoppers differ in terms of socio-economic status, personal characteristics and shopping behaviour. The findings provide information useful to both retailing and manufacturing interests as retail marketing strategies are developed in the face of intensifying competition for shoppers' food expenditure in the market-place. 相似文献

The Masakhane Campaign in South Africa has received a fair amount of criticism, largely because its high media profile has not been accompanied by delivery and improvement of services at the local level. Contrary to this generally negative perception, there are a number of local authorities that have greatly improved the situation in their areas through pragmatic strategies and programmes under the banner of Masakhane. This article presents information on the current status of the campaign in a sample of local authorities, and attempts to interpret this information so as to ascertain those factors that influence on the success or failure of local authorities as service providers. 相似文献
