Outsourcing of research and development (R&D) activities has become a major management issue for R&D and technical managers within firms. It has also been of growing concern to academics who are trying to chart the implications of the increasingly distributed nature of research and innovative activities in advanced economies. This study is based on a survey of research-based pharmaceutical companies operating in the United Kingdom conducted in 2004–2006. The aim of this paper is to outline the main reasons for pharmaceutical firms to outsource R&D and the management practices followed by such companies in relation to outsourcing. The research results provide interesting findings in relation to, for example, the reasons behind outsourcing, the decision-making processes behind such practices and barriers to outsourcing arrangements. These issues are evaluated together with the characteristics of the firms and the specific project outsourced.  相似文献

This paper examines the admissibility of some selection criteria in the light of European public procurement law. It also points out the opportunity of using such criteria through an economic analysis. The main aspect to be dealt with is the numerical selection criteria, which may hinder firms not fulfilling them from participating in the award procedure. These criteria refer, according to the European Union directives on public procurement, to the economic, financial, and technical capacity of the candidate firms. In our analysis, the legal appreciation should be confronted with an economic analysis of the numerical selection criteria. This analysis is based on an arithmetic approach which focuses on relative rather than absolute values. Thus, through a series of performance indicators, an alternative approach to the above criteria is presented. This paper does not reflect the official position of the Commission of the EU.  相似文献

The purpose of this article is to study relative trends in total factor productivity (TFP) between the Australian and New Zealand manufacturing sectors from 1986 to 1996. Since 1984 both economies have undergone major structural changes with varying degrees of speed and intensity. We use the Malmquist index to measure TFP growth and decompose it into an efficiency change and a technical change component. This decomposition provides extra insight on assessing relative productivity trends during a period of economic reform. The results indicate the Australian manufacturing sector exhibits better rates of individual factor productivity performance while multifactor productivity is estimated to be higher in New Zealand manufacturing. TFP growth in New Zealand is driven by technical rather than efficiency change. In fact, the New Zealand manufacturing average rate of efficiency change is estimated to be negative over the sample period.  相似文献

In this paper, we seek to demonstrate the predictability of stock market returns and explain the nature of this return predictability. To this end, we introduce investors with different investment horizons into the news-driven, analytic, agent-based market model developed in Gusev et al. [Algo. Finance, 2015, 4, 5–51]. This heterogeneous framework enables us to capture dynamics at multiple timescales, expanding the model’s applications and improving precision. We study the heterogeneous model theoretically and empirically to highlight essential mechanisms underlying certain market behaviours, such as transitions between bull and bear markets and the self-similar behaviour of price changes. Most importantly, we apply this model to show that the stock market is nearly efficient on intraday timescales, adjusting quickly to incoming news, but becomes inefficient on longer timescales, where news may have a long-lasting nonlinear impact on dynamics, attributable to a feedback mechanism acting over these horizons. Then, using the model, we design algorithmic strategies that utilize news flow, quantified and measured, as the only input to trade on market return forecasts over multiple horizons, from days to months. The backtested results suggest that the return is predictable to the extent that successful trading strategies can be constructed to harness this predictability.  相似文献

This study investigates the dynamic relationship between crude oil and retail gasoline prices during the last 21 years and determines that, in February 1986, the relationship had drastically changed. Since that date, the results show that gasoline prices include higher profit margins, respond substantially less to changes in crude oil prices(but still within one month), and are more volatile. Also discussed are the developments in crude oil and gasoline markets that have led to the above changes.  相似文献

In the past two decades, Brazil, South Africa and China have designed closer economic and political ties. Since the early 2000s, China has become a key economic partner for both countries. International trade and foreign direct investment between the three nations have expanded, and closer political ties have also evolved. This article elaborates on the increasing economic interdependence between Brazil, China, and South Africa addressing challenges and opportunities for all three countries involved.  相似文献

In this paper we investigate the existence of profit opportunities in the Greek market for the 6/49 Lotto. Under the assumption of random number selection we find evidence suggesting that the market is efficient. Because number selection is found to deviate from randomness, we further investigate the existence of profit opportunities due to number unpopularity. The evidence suggests that although unpopular numbers exist, they are not sufficiently unpopular so as to generate positive expected payoffs.  相似文献

This essay studies the diffusion/adoption of Web 2.0 technologies in small and medium sized enterprises (SMEs)’ innovation strategies and particularly in research, development, design and other innovation activities. It looks at the effects of these technologies on the evolution and the dynamics of firm's innovation capabilities and the implications of entrepreneurial turnover on the adoption of said technologies. The study is based on original fieldwork with some 130 SMEs. The author finds that a consistent share of SMEs is actively trying to fill the knowledge gap and integrate Web 2.0 technologies in their innovation strategies. SMEs are managing this integration by progressively adjusting their behaviour in reaction to the opportunities offered by the technology and balancing the dependence of the business from the web. Barriers to the adoption of such technologies are also discussed.  相似文献

This paper reports an experimental test of the relative efficiency of a whistleblowing-based audit scheme compared to a random-based audit scheme. We design a between-subjects laboratory experiment with two treatments: a benchmark with a random-based audit scheme and an alternative treatment in which taxpayers can blow the whistle. Compared to the benchmark, the whistleblowing-based audit scheme (i) improves the targeting of evaders, (ii) decreases the monetary amount of tax evasion, and (iii) raises the tax levy.  相似文献
