In the context of the classical stochastic growth model, we provide a simple proof that the optimal capital sequence is strictly bounded away from zero whenever the initial capital is strictly positive. We assume that the utility function is bounded below and the shocks affecting output are bounded. However, the proof does not require an interval shock space, thus, admitting both discrete and continuous shocks. Further, we allow for finite marginal product at zero capital. Finally, we use our result to show that any optimal capital sequence converges globally to a unique invariant distribution, which is bounded away from zero.  相似文献

Using a sample of U.S. firms over the period 1996–2014, this paper examines whether insider trading profitability increases with high board co-option. Indeed, we find that firms with a higher level of co-opted directors exhibit higher insider trading profitability, largely due to a lower level of managerial ability and analyst coverage. Co-opted boards are also unlikely to implement self-imposed insider trading restrictions, exacerbating this relationship. This positive association is mitigated by a higher level of external monitoring by institutional investors and if the CEO receives more performance-based incentives. Overall, co-opted directors demonstrate aligned interests with CEOs and corporate insiders rather than performing their role as monitors. As a result, a more co-opted board is positively associated with exploitative behaviour of insiders.  相似文献

The effects of monetary policies remain always an important topic in macroeconomics. In the literature (closed and open economy), there is no theoretical as well as empirical consensus regarding the effects of monetary policies. In this paper we examine the real effects of inflation in an open economy. Australia is a classic example of a small open economy and is known to exercise inflation targeting. Using quarterly data from Australia and employing vector autoregressive (VAR) analysis, we provide evidence that inflation, both in the short and long run, negatively affects durable and non‐durable consumption and investment, and has a positive effect on the current account. Further, we show that consumption of durable goods is more sensitive than the consumption of non‐durables during the initial periods following inflationary shocks.  相似文献

I develop a principal-agent model of environmental regulation in which the regulator can acquire two costly signals of the firm’s abatement effort. Acquisition of the second signal is conditioned on the observed value of the first, emissions signal. The optimal contract takes the form of an emissions standard when only the emissions signal is acquired, and a set of contingent emissions standards when both signals are acquired; the standards are coupled with uniform, maximal penalties for noncompliance. Acquisition of the second signal may be optimal when intermediate values of the first signal are observed but not when extreme values are observed.   相似文献

In this paper we show that inflation, both in the short and long run, negatively affects durable and non-durable consumption and output, and positively influences the current account balance. In particular, the impact of inflation is more pronounced on durable relative to non-durable goods. Using quarterly data from Canada, the UK and the USA, we demonstrate that these findings are consistent and robust across different econometric specifications. An open economy model with durable and non-durable consumption, households with labor/leisure choice and money introduced through cash-in-advance (CIA) constraint on consumption expenditure alone could meaningfully explain these empirical observations. Our empirical findings of non-neutral and negative effects of inflation on real growth are significant for many economic models in the asset pricing literature that support a negative co-movement of stock prices and expected inflation. Moreover, such positive inflation premium in our model could provide economic explanation for a positive slope of the nominal term structure in the data.  相似文献

A steady demand for green products from concerned consumers has led companies to introduce new product lines that match or exceed consumer environmental concerns. Nonetheless, not all the organizations were able to achieve significant returns on their investments in green products. These failures are generally attributed towards companies’ inability to overcome consumer scepticism towards the performance of functional and green attributes of their brands to generate a positive green image and green value in consumers mind. Therefore, the question arises that does the success in promoting green brand image and value depend on consumer existing perceptions about the brand quality and credibility? This study analyzes the influence of brand perceive quality and credibility on consumer perceptions towards a brand green image, green value and green equity. A theoretical model with hypothesized relationships is developed and tested to answer these research questions. Data have been collected from the consumers of electrical and electronic goods. The hypothesized relationships were tested with the help of structural equation modeling procedure. The results suggest that brand perceived quality and its overall credibility does have a significant influence on generating a greener image, green perceive value and green brand equity.  相似文献

The concept of drone usage for commercial purposes by retailers worldwide is still in its early stages, and unheard of in Pakistan. Moreover, research on consumer perceptions regarding commercial drones in Pakistan and around the world is very sparse. The purpose of this paper is to gauge the level of acceptability and concerns Pakistani consumers may have in accepting the drone delivery technology. This study offers new insights that retailers and delivery companies can use to penetrate target markets in early stages. The authors have executed a quantitative analysis through the means of a survey. A sample of middle‐ and upper class residents of two cities in Pakistan was selected on which purposive sampling technique was applied. A total of 307 responses were collected and these responses were analysed in SPSS. Various analysis techniques were applied including Cronbach’s alpha, the Pearson correlation analysis, regression analysis and cluster analysis. The results show that consumers in Pakistan perceive privacy issues as a primary concern in relation to drone delivery. The results also throw light on the profile of consumer segments that can be targeted by retailers who may desire to use the drone delivery technology in the near future. Using these findings, retailers using the drone delivery mechanism can address consumer’s fears and ambiguities. Retailers can resolve consumer concerns by designing pro‐privacy parameters in the initial service design stage and the infrastructure deployment of drones.  相似文献

Set in the context of internationalization of the global division of labor, this article provides a deeper exploration of qualitative themes of conflicting accounts of employees’ reasons to quit and managerial strategies to prevent employee turnover in six business process outsourcing firms operating in India. Such differences in cognition and action between the two constituencies suggest that the decision to quit is not a linear and rational process as highlighted in most extant models of employee turnover. Our findings suggest that employees are attached more to a place or people they work with rather than the organization per se. Intergenerational differences between Generation Y knowledge workers and Generation X managers and the ineffectiveness of espoused human resource practices suggest the presence of “push” human resource management (HRM) systems. Our findings have implications for employee turnover models, intergenerational theory and high‐commitment HRM, and practitioners. © 2015 Wiley Periodicals, Inc.  相似文献

Literature has highlighted but not explored links between knowledge sharing and learning at inter‐firm and intra‐firm levels. Using the single case of an aviation refuelling company as the basis for our research methodology and collecting data through 34 semi‐structured interviews, we develop a framework that integrates knowledge sharing and learning at inter‐firm and intra‐firm levels. We show that intra‐firm knowledge sharing capabilities facilitate the diffusion of inter‐firm learning within organizations. Moreover, inter‐firm trust manifests in different forms that affect individual and organizational learning. The purpose of collaboration determines what a firm learns or discards. The findings are important for organizations facing a shortage of skills. © 2018 ASAC. Published by John Wiley & Sons, Ltd.  相似文献
