An integrated framework that combines spatial and biophysical attributes of land with a hydrological model and an economic model is developed to identify cropland for enrollment in the Conservation Reserve Enhancement Program. Sediment deposition coefficients are determined endogenously depending on the land-use decisions on other land parcels. Application of this framework to a watershed in Illinois demonstrates that highly sloping land adjacent to water bodies should be selected for retirement. A marginal value rental payment scheme can achieve program goals of 20% sediment abatement at 39% lower cost than a productivity-based rental scheme.  相似文献

Stochastic dynamic programming is used to investigate optimal holding of primary tropical forest in humid Costa Rica when future nonuse benefits of forest conservation are uncertain and increasing. The quasi-option value of maintaining primary forests is included as a component of investment in natural capital. Although the impact of uncertainty on conservation incentives is substantial, our results indicate that a rising trend in future benefits and compensation by the international community for beneficial spillovers are more important factors in determining optimal holdings of forest stocks. Without compensatory payments, however, further deforestation may be warranted.  相似文献

Existing tax policies have many complex features that make distinctions across goods, factors, and financial structures that distort economic allocations. Their importance is ignored when tax policy is summarized by an “effective” tax rate. In fact, the losses due to asymmetries are often larger than the losses due to the level of taxation.  相似文献

In this study, we examine whether the public debt market prices information on off‐balance sheet debt arising from operating leases and postretirement plans. We find that bond‐rating agencies price off‐balance sheet debt arising from operating leases and the coefficient on off‐balance sheet debt measure of operating leases is similar to that of capital leases on the balance sheet. Regarding postretirement benefit plans, we find that bond‐rating agencies do price postretirement benefit obligations that are reported in balance sheet but do not price such obligations disclosed in footnotes. We find similar results when we examine corporate bond yields on new debt issues.  相似文献

提高直接融资比重,大力发展债券市场是十二五资本市场发展的一大重点。本文首先对企业在银行贷款和公开发行债券之间的取舍做了理论文献回顾,然后以2005年初至2010年底公开发行债券的上市公司及未发行债券的匹配公司为样本,从企业融资决策的角度,实证检验我国企业债务融资方式的主要影响因素。发现与国外债券市场情况相似,企业发展前景、财务状况和企业规模是影响企业债务融资决策的重要因素。  相似文献

Increasingly, public sector organizations (PSOs) outsource the delivering of important welfare services. This gives rise to important questions of how PSOs can control their suppliers. The purpose of this paper is to show how PSOs manage cooperation hazards of low contractibility transactions, i.e., activities expected to be difficult to govern. The paper applies a taxonomic configuration approach which means we apply a holistic view on the governance of suppliers and search for internally congruent governance packages that also are adapted to the context of the transactions. We find indications of the importance of internal congruence in governance packages in order to effectively deal with cooperation hazards. We also notice that the intensity in and types of controls in inter-organizational relationships are affected by the amount of cooperation hazards. A conflict between a relational and a bureaucracy-based governance package in one of the configurations is argued to be the main driver behind lower expectations about positive behaviour from suppliers.  相似文献

We present a portfolio decision model for banks that permits us to estimate the costs associated with the need to collateralise loans from the central bank. This allows us to calibrate the difference between a restrictive collateral eligibility framework for open market operations, such as that applied by the FED, with a more flexible approach such as that of Eurosystem. We also document that there could potentially appear relevant cost differences between the various collateral mobilisation procedures (pooling and earmarking) that currently coexist in the eurozone.  相似文献
