Land Tenure and the Adoption of Conservation Practices 总被引:7,自引:0,他引:7
Meredith J. Soule Abebayehu Tegene & Keith D. Wiebe 《American journal of agricultural economics》2000,82(4):993-1005
We use a logit adoption model with data on 941 U.S. corn producers from the 1996 Agricultural Resource Management Study to analyze the influence of land tenure on the adoption of conservation practices. We extend previous analyses by distinguishing renters according to lease type and by distinguishing practices according to the timing of costs and returns. We find that cash-renters are less likely than owner-operators to use conservation tillage, but share-renters are not. Both cash-renters and share-renters are less likely than owner-operators to adopt practices that provide benefits only over the longer term (grassed waterways, stripcropping, and contour farming). 相似文献

Freight on Transit (FOT) refers to an operational strategy where public transit vehicles and/or infrastructure are used to move freight. Examples include moving goods alongside passengers on buses, attaching cargo trailers to transit vehicles, and operating freight vehicles between trains on subway lines. This paper describes the methods and results of a three-round Delphi study engaging 34 transportation experts to explore challenges and opportunities of FOT and to conceptualize and evaluate potential FOT operations in Toronto. Traditional Delphi methods were used for the exploration of FOT challenges and opportunities, and a modified approach was formulated to integrate experts' opinions and develop new FOT concepts for Toronto. The results support previous claims that technical challenges of FOT may be easier to overcome than institutional barriers. Evaluation of potential FOT operating strategies in Toronto suggests that while the current public transit network does not have capacity to support additional movements, there may be realistic opportunities to include freight service in future projects as a means of offsetting operating costs and reducing the impacts of goods movements. 相似文献

ABSTRACTPotential biofuel demand in South Africa is estimated to increase to 1550 million litres by 2025 due to mandatory blending rates. Land and water constraints, however, limit the ability for domestic production. Zambia, due to its abundance in land, suitable climate, supportive set of bioenergy incentives and close geographical location to South Africa, has the potential to meet this increase in demand. Using a dynamic recursive computable general equilibrium model, we estimate the macro- and socio-economic impacts of bioethanol production in Zambia from three potential crops: sugarcane, cassava and sweet sorghum. The results show that the development of a single product bioethanol industry has the potential to increase economic growth without negatively affecting overall food security. Further expansion of the industry to multiple products results in larger gains to growth and welfare. 相似文献

Ethical dilemmas involving tax issues were identified by members of the American Institute of Certified Public Accountants
as posing the most difficult ethical problem for them (Finn et al., Journal of Business Ethics
7(8), pp. 607–609, 1988). The KPMG tax shelter fraud case proves that the tax profession has not gone untainted in the age
of numerous accounting and corporate scandals, such as the Enron débacle (Sikka and Hampton, Accounting Forum
29(3), 325–343, 2005). High-profile scandals serve to highlight the problems caused by differences in ethical judgement among
accountants and tax practitioners and the issue of ethics has been brought publicly to the forefront of the profession. Nevertheless,
the nature and dimension of ethical issues in tax practice have been largely unexplored (Erard, Journal of Public Economics
52(2), 163–197, 1993; Marshall et al., Journal of Business Ethics
17(12), 1265–1279, 1998; Frecknall Hughes, Unpublished PhD Thesis, The University of Leeds, 2002). This research aims to contribute
to the debate on ethics in tax practice by reporting interview data on tax practitioners’ perceptions of ethics in the jurisdictions
of Ireland and the United Kingdom and exploring the link or equation of ethics with risk management. 相似文献

Researchers have investigated a number of different psychological constructs that occur as a result of advertising exposure and that contribute toward the formation of attitudes toward the ad (Aad) and brand (Ab). The dual mediation model (DMM), which defines hypothesized interrelationships among these constructs, has been well supported in previous research, but fails to empirically distinguish between the quantitative versus qualitative effects that can occur as a result of increased elaboration. To address this issue, the author incorporates cognitive resource matching theory into the DMM framework, arguing that construct means, the relative proportions of those means, and the links among model constructs are moderated by level of processing motivation. The results of empirical testing of a modified version of the DMM under alternate resource conditions are consistent with this theoretical explanation. © 2005 Wiley Periodicals, Inc. 相似文献

This paper estimates the degree of risk aversion from one of the most popular TV gameshows ever. The format of the show is straightforward; it involves no strategic decision making; we have a large number of observations; and the prizes are cash, which is paid immediately and covers a large range: from £100 up to £1 million. We provide non‐parametric estimates of the utility function and then we test some parametric restrictions. We find that, although the restriction to CRRA utility is statistically rejected, a log function approximates the utility function quite well over a large range of potential winnings.

This paper summarises the results of a detailed examination of the contents of explanatory notes of Statements of Standard Accounting Practice. The presentation of argument in the explanatory notes is discussed in the light of recent writings on rhetoric, and the Accounting Standards Committee is assessed in terms of its performance as a persuader rather than by reference to the substantive requirements of SSAPs. The paper suggests that changes in the structure of future accounting standards would be desirable, and concludes by linking the rhetorical perspective to the notion of a conceptual framework. 相似文献

Explicit matrix representations of solution concepts in a graph model of a multiple-decision-maker conflict with preference
uncertainty are developed. In a graph model, the relative preferences of each DM over the available states are crucial in
determining which states are stable according to any stability definition (solution concept). Unfortunately, it is often difficult
to obtain accurate preference information in practical cases, so models that allow preference uncertainty can be very useful.
In this work, stability definitions are extended to apply to graph models with this feature. The extension is easiest to implement
using the matrix representation of a conflict model, which was developed to ease the coding of logically-defined stability
definitions. Another benefit of matrix representation is that it facilitates modification and extension of the definitions. 相似文献

Causal inference using statistical models plays a central role in many areas of behavioral science, but the underlying metatheory
of causal explanation remains poorly developed. Mulaik’s work on causation offers a useful foray into this topic. Evaluation
of two negative arguments applied to a broad range of theories of causation offer overdue critical assessment of this contribution.
More broadly, the critical evaluation of Mulaik’s arguments speak to the need for better integration of substantive theories
and statistical models in causal research. 相似文献
