We construct a simple model of education and growth in which children spend a fraction of their time and parents spend a fraction of their income on education. Both a strategic complementarity and an intergenerational externality are present. The interactions between each pair of consecutive generations lead to rich dynamics. We show that multiple growth equilibria arise, some of them periodic and some aperiodic. We also find a negative correlation between volatility and growth, without a one‐way causal relationship between the two being, necessarily, present. Rather, this negative correlation is driven by the structural characteristics of the economy.  相似文献

The centrality of cross‐functional integration (CFI) to supply chain theory and practice has long been recognized. Yet researchers continue to struggle with consistently defining or measuring the CFI construct, thus limiting the utility of CFI research. This research develops (1) a comprehensive definition of CFI that synthesizes previous supply chain research and (2) a valid set of scale items that measure the conceptual domain outlined by this definition. The goal is to build a common foundation for extending knowledge on CFI's antecedents and consequences, and ultimately to improve scholars’ ability to guide a broader practitioner community still struggling to achieve integration in their organizations.  相似文献

Construction prices are lower in developing countries in ICP 2005, which has raised these countries' capital/output ratio in Penn World Tables 7 and 8 and affected growth analyses. We estimate the Colombia/U.S. price ratio for office and apartment buildings in 2005 as a test of the validity of the ICP 2005 methodology for estimating these prices. Our estimate of the Colombia/U.S. price ratio is almost twice the ICP 2005 estimate. We confirm the validity of our results by estimating the cost of constructing office and apartment buildings using 2005 prices for construction materials, equipment, and labor in both countries.  相似文献

The pace, complexity, and globalization of change requires attention to the future. The change of millennia — the coming of the year 2001 — provides an opportunity, a psychological focus, for a global review of past achievements and problems and a unique chance to assess and reflect on future issues and opportunities.Unfortunately, there is as yet no mechanism or information utility to support a worldwide effort to study past achievements and problems or future issues and opportunities. Although there are many individual, isolated, special purpose, and one-time study efforts underway, there is no international system that can provide coherence or continuity to these studies, including feedback and sharing of information, and, in particular, the systematic exploration of future possibilities and policy alternatives. With growing interest in the future, the spread of instantaneous and global communications, the advent of powerful new nondeterministic modeling techniques, the ability to evoke, capture, and share information and perceptions with systematic questioning techniques and software, the proliferation of data bases, and knowledge visualization, it is now possible for futurists, scholars and others around the world to interact globally and take a fresh look at the future possibilities and policies in ways not previously possible.As the World Bank provides an ongoing system for research and feedback to improve economic policy, so too the United Nations University could provide an ongoing system for the improvement of futures research and its application to the policy process. According to a series of interviews, questionnaires, and meetings with leading futurists and scholars around the world, the proposed “Millenium Project” has the potential to become such a system.This study had as its principal objective determining the design of an information system that could effectively tap contributors, worldwide, to focus on lessons of the past that bear on world issues and the potential of future developments for intensifying or mitigating these and future issues. The first phase of the feasibility study was both methodological and substantive. Worldwide panels of experts contributed their judgments about the method or process of organizing the project; and the system that emerged from this interaction was applied in a prototype study to the issues of growing world population and the environment.During the first phase of the feasibility study, we found that:
1. 1. The Millennium Project is feasible and likely to be helpful to many institutions in examining and resolving policy issues at several levels. An overview of the project design and objectives appears in Section 2 of this article.
2. 2. Organizations that have an issues scanning function, or have a mandate to keep abreast of a broad range of futures thinking, have a need for access to a non-political, scholarly, and international system of future studies. Such organizations have requested continued participation in the second and third phase of this feasibility study, as well as establishing formal relations with the full Millennium Project.
3. 3. While several questions remain, the design features of a system to collect judgments using the Delphi process that were suggested by the international panel (outlined elsewhere in this report) form a straight forward operational system. Among the remaining questions are the design and use of international information systems and data bases, integration with quantitative techniques such as system modeling, the requirements for special study teams, and institutionalization and financial support. The design of the operational system is described in detail in Section 3 of this report.
4. 4. Cost estimates have been made for establishing international panels and collecting and analyzing information they provide using the Delphi process. Several assumptions are required. If a maximum of four topics are addressed in a particular year, each of the four panels consists of 150–200 people, the staff is kept to a base of three people with an additional 1.5 per panel, and advisors are paid an honorarium of $1.500, then the cost of this element of the full scale Project is likely to be approximately $900,000 per year. While communications modes are important in terms of timing and information access, the costs of communications are the smallest of the Project's cost elements. Detail of our cost estimates appear in Section 7 of this report.
This is not the final feasibility study report, but only a report on part of Phase I. As such, it contains our initial findings about how the Project might be organized. We welcome comments from the reader. Please consider this as work in progress.  相似文献

We survey managers of Nasdaq firms that consistently pay cash dividends to determine their views about dividend policy, the relationship between dividend policy and value, and four common explanations for paying dividends. The evidence shows that managers stress the importance of maintaining dividend continuity and widely agree that changes in dividends affect firm value. Managers give the strongest support to a signaling explanation for paying dividends, weak to little support for the tax-preference and agency cost explanations, and no support to the bird-in-the-hand explanation. The study provides new evidence about how managers view dividend life cycles and residual dividend policy. The authors would like to thank two anonymous referees for helpful comments and suggestions, and Maheshan Fernando and Sumeet Chawla for providing research assistance.  相似文献

It is well known that a nonlinear recursive equation can produce a chaotic sequence at certain values of the parameter. Furthermore, in the chaotic regime, extremely small changes in the initial value or in the value of the parameter produce very large changes in the sequence. It is surprising therefore that a short segment of a chaotic sequence can be used to reconstruct large portions of the sequence and to forecast future values of the sequence over short ranges. Furthermore, while the accuracy of the forecasts is dependent on the precision of the data, the relationship is much less sensitive than might have been expected. This is demonstrated by fitting a two-parameter model to two different types of chaotic equations: one a polynomial and the other a trigonometric function. This leads to the expectation that under certain circumstances, it may be possible to forecast values in a chaotic series over limited ranges, even if initial data are somewhat degraded.  相似文献

Managers with different cultural backgrounds and under different circumstances have different views on what is acceptable ethical behaviour. This study attempts to determine whether major companies in Hong Kong share the same views as North American academics on what management ethical standards ought to be, and if so, whether any control mechanisms have been established to instill ethical behaviour within their organizations. Notable differences between the practice in these companies and those from a similar survey conducted in North America are identified and explained. The management accountant's role in the development and implementation of such mechanisms is investigated.  相似文献

This paper addresses the joint optimization of capacity investments and toll charges imposed on multi-group users in monopolistic private highways within general road networks. A game-theoretic formulation is provided that leads to a nonconvex bilevel program. The proposed modeling framework handles several complex issues raised in realistic applications, such as regulations on the levels of tolls and service, and the discrete nature of highway capacity, using a genetic optimization technique. Real-application results show the importance of considering the spatial heterogeneity of prices, and the tradeoff between investments and pricing strategies in regulated private highways.  相似文献

An evaluation of SFAS No. 130 comprehensive income disclosures   总被引:3,自引:0,他引:3  
In this study, we provide evidence on the pricing of other comprehensive income (OCI) that differs from most evidence in prior research. Prior archival research has largely concluded that OCI is not priced by investors. In contrast, we provide evidence in the post-SFAS 130 period that OCI is priced on a dollar-for-dollar basis as is predicted by economic theory for transitory income items. We attribute this finding to our use of post-SFAS 130 as-reported measures of OCI rather than pre-SFAS 130 as-if estimates of OCI measures. Furthermore, we document that two components of OCI, foreign currency translation adjustment and unrealized gains/losses on available-for-sale securities, are priced by investors. In the post-SFAS 130 period, we also find that the type of financial statement in which firms report OCI and its components affects pricing, consistent with the conclusions of prior experimental research. However, our evidence suggests that investors pay greater attention to OCI information reported in the statement of changes in equity, rather than in a statement of financial performance. This could be attributed to investors becoming more familiar in the post-SFAS 130 period with the predominant reporting of OCI and its components in the statement of changes in equity. These findings may be relevant to both the Financial Accounting Standards Board and the International Accounting Standards Board, which jointly are undertaking a new project that, in part, is addressing financial statement presentation of OCI items.
