This paper presents the results of an investigation into the determinants of retirement planning behaviour and differences among three age groups: 21‐ to 39‐year‐olds, 40‐ to 59‐year‐olds and those aged 60 years and older. A national survey of 911 individuals from households with incomes of $75 000 or greater was conducted in the US. The significance of socio‐demographic variables, the ability to recover from loss, behavioural tendencies and perceived or actual personal control were investigated; together with their role in the prediction of maximization of retirement contributions and ownership in the personal individual retirement account (IRA) or Keogh accounts. The results identified several significant variables in the prediction of ownership in a personal IRA or Keogh, including age, sources of financial information, being an early investor and investor activity. The results also identified several significant variables in the prediction of the maximization of retirement contributions, including employment, income, savings activity, ex ante research, review of investment performance, early investor, investor activity, such as planning for financial future, setting up automatic deposits and reviewing financial information in the mail.  相似文献

Recent technological changes in many industries have generated numerous complementary technologies. A key implication of complementary technologies is that the demand for related services has tended to change both qualitatively and quantitatively. While the economics literature has examined various aspects, the effects of technological complementarity have not been fully flushed out. Using a simple model, this paper examines the implications of technological complementarity. How have firms’ pricing abilities changed with complementary technologies? What implications do complementary technologies have for regulation? Results show that technological complementarity has the potential to increase the market power of firms, possibly increasing prices to unprecedented levels. This holds whether demand elasticity is constant or variable. Policy implications are discussed.  相似文献

Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible.  相似文献

This paper focuses on the integrative and pervasive use of microcomputers in marketing research and managerial decision making. The marketing research process is conceptualized as consisting of six phases. At each phase, microcomputer applications and illustrative software are identified as implications for the practice of marketing research discussed. Next the paper illustrates the use of microcomputers in selected application areas such as market segmentation, sales forecasting, new product development, pricing and decision support and expert systems. Guidelines for the selection of microcomputer software in specific situations are provided. The paper concludes with some observations on the future applications of microcomputers in marketing research and decision making.  相似文献

People have planted trees in rural places with increasing frequency during the past two decades, but the circumstances in which they plant and the social forces inducing them to plant remain unclear. While forests that produce wood for industrial uses comprise an increasing number of the plantations, most of the growth has occurred in Asia where plantations that produce wood for local consumption remain important. Explanations for these trends take economic, political, and human ecological forms. Growth in urban and global markets for forest products, coupled with rural to urban migration, may spur the conversion of fields into tree farms. Government programs also stimulate tree planting. These programs occur frequently in nations with high population densities. Quantitative, cross-national analyses suggest that these forces combine in regionally distinctive ways to promote the expansion of forest plantations. In Africa and Asia plantations have expanded most rapidly in nations with densely populated rural districts, rural to urban migration, and government policies that promote tree planting. In the Americas and Oceania plantations have expanded rapidly in countries with relatively stable rural populations, low densities, and extensive tracts of land in pasture. If, as anticipated, the growing concern with global warming spurs further expansion in forest plantations in an effort to sequester carbon, questions about their social and ecological effects should become more pressing.  相似文献

Sowing phases of French serradella (Ornithopus sativus Brot.) pasture between extended cropping sequences in the Western Australian wheatbelt can sustain grain production through restoring soil fertility and reducing selective herbicide use. The objective of this article is to investigate the profitability of rotations involving this pasture under a variety of weed management scenarios to obtain greater insight into its value for mixed farming systems in this region. A stochastic search procedure, compressed annealing, is used to identify profitable sets of weed management strategies in a simulation model representing a large number of potential combinations of chemical and non‐chemical forms of weed control. In contrast to a continuous‐cropping sequence, the inclusion of a serradella phase in a rotation is profitable at high weed densities and with increasing levels of herbicide resistance. A single year of pasture in the rotation is optimal if resistance to Group A selective herbicides is present at the beginning of the planning horizon, but a three‐year phase is required if resistance to multiple herbicide groups is observed. Sowing a serradella pasture twice over a two‐year phase is also shown to be economically attractive given benefits of successive high weed kills.  相似文献

Little research attention has been devoted to the impact of salesperson failure and recovery management on customer relationship development. This paper develops a theoretically anchored and externally validated sales recovery audit for the purpose of assessing sales organization performance in these matters. Results based on a survey of 177 sales managers indicate that practice of sales recovery efforts lags behind their perceived importance as they relate to organizational success. The sales recovery audit presented here can be a useful tool to continuously evaluate and enhance sales recovery efforts for the purpose of building a stronger relationship selling organization.  相似文献

Despite the ongoing search for the so-called silver bullet that provides the ultimate competitive advantage, there is no roadmap showing the “right” way to perform new product development (NPD). What's more, it is highly unlikely that such a formula could be developed. Given the diversity of firms and industries as well as the complexity of the NPD process, no single set of NPD activities or steps can be defined that will be appropriate for all firms. However, Roger J. Calantone, Shawnee K. Vickery, and Cornelia Droge propose that it is possible to develop such a framework within the confines of a specific industry. They suggest that successful companies within an industry are likely to focus on certain essential NPD activities that allow them to achieve the best possible results within the constraints of their market. Their research is directed toward identifying the relationship between the performance of specific innovation-related activities and overall business performance in the furniture industry. This study also assesses the relationship between a firm's performance on an NPD activity and the importance assigned to that activity by the firm's chief executive officer (CEO). With the current emphasis on cross-functional teams, the study also seeks to determine whether performance on a given NPD activity is related to the assignment of responsibility for that activity. The following NPD activities were evaluated for their effect on corporate performance: customization, new product introduction, design innovation, product development cycle time, product technological innovation, product improvement, new product development, and original product development. Compared to their competitors, top performers consistently put more strategic emphasis on each of these activities. All of these activities have a strong positive influence on return on investment (ROI) and ROI growth. What's more, most of the activities also clearly relate to stronger market share, market share growth, return on sales (ROS), and ROS growth. The vision and focus on these essential NPD activities must begin with CEOs who recognize their strategic value. Such leaders will direct appropriate staff and technical resources toward performance of the necessary activities. They will also ensure that the organization is sufficiently flexible to accept the changes in responsibilities for coordination and leadership that are necessary during different stages in the NPD process. To gain the product flexibility necessary for competing in numerous market segments, top performers require greater input and leadership from design, engineering, and manufacturing.  相似文献

This paper investigates the international transmission of fiscal shocks between two closely‐linked, open economies. We estimate impulse response functions using a semi‐structural vector auto regressive (VAR) model and quarterly data from Australia and New Zealand for the period 1973:3–2008:4. We compare our empirical results with impulse response functions from a calibrated two‐country international real business cycle model with habit formation and adjustment costs to investment. We show that a positive shock to Australian government consumption leads to an increase in Australian output initially and then to a decline in the medium term, while the New Zealand output is negatively affected both in the short and medium term. This result is in line with the recent literature that reports beggar‐thy‐neighbour effect of positive government spending shocks.  相似文献
