Consider a game whose strategies are \"contributions\". A strategy profile is a Kantian equilibrium if no player would like all players to alter their contributions by the same multiplicative factor. Kantian equilibria are Pareto efficient. We characterize the allocation rules on several domains of environments that can be implemented as Kantian equilibria. The concept unifies the proportional solution on production economies and the linear cost-share equilibrium on public-good economies. We study Kantian equilibrium in the prisoner's dilemma, in a voting problem, and in a political economy where redistribution is the issue. The Kantian dictum engenders considerable but not unqualified cooperation.

Mid-rotation management practices for pine (Pinus spp.) plantations enrolled in cost-share programs have not been widely evaluated for wildlife. Mid-rotation pine plantations often have a substantial hardwood mid-story that limits growth of desirable understory forage species important to white-tailed deer (Odocoileus virginianus; deer). We treated with imazapyr herbicide and prescribed burning (HB) 11 thinned, 13–22-year-old loblolly pine (P. taeda) plantations in the Upper Coastal Plain (UCP; n = 5) and the Lower Coastal Plain (LCP; n = 6) of Mississippi, USA, enrolled in cost-share programs. We then sampled these plantations for production of important deer forages during July of 2003 and 2004, years 1 and 2 posttreatment. Deer foraging habitat was clearly improved by the HB treatment in both regions by year 2. Forb species of annual importance to deer increased in percent cover and biomass in the UCP and in biomass in the LCP. We estimated nutritional carrying capacity using a target diet quality of 14% crude protein; estimates in HB plots were 3 times greater than controls in the UCP and 19 times greater in the LCP. Although UCP sites had baseline carrying capacities nearly 8 times greater than LCP sites, the greater relative response to HB in the LCP eliminated the regional difference. Our results indicate that imazapyr herbicide treatment followed by prescribed fire is a beneficial tool for deer management in mid-rotation pine plantations.

Cover crops can generate both on-farm and water-quality benefits. However, their use in Iowa remains subdued, partly due to implementation costs faced by farmers. We tested the hypothesis that monetary incentives through cost-share programs are effective at increasing the area of farmland planted to cover crops in Iowa, as opposed to the alternative in which the participants of cost-share programs would have planted the same cover-crop acreage in the absence of payment. We found that cost-share payments induced a 15 percentage-point expansion in cover-crop acreage beyond what would have been planted in the absence of payment, among farmers who participated in cost-share programs. The estimated additionality rate was 54%, suggesting at least half of cost-share expenditures funded cover-crop acreage that would not have been planted without payment. Furthermore, we estimated the public cost to reduce nitrogen loads to Iowa waterways via cover crop, beyond what would have occurred in the absence of cost-share programs, to be$1.72–$ 4.70 lb −1 N ( $3.79–$ 10.36 kg −1 N). Farmers absorbed about 70% of those costs as private losses, and cost-share payments offset the remaining 30%. Although the additionality rate estimated in this study is less than what has been found in other states, the cost-share programs in Iowa have been relatively cost-effective, due to their lower payment rate.

Natural resource agencies in the United States continue to design and expand technical and financial assistance programs that benefit private landowners managing for wildlife. Cattle ranchers, one of the primary stakeholders, are well poised to benefit from these programs, especially if they can easily integrate wildlife management activities into cattle operations. A key component to implementing successful wildlife management programs on ranches is to understand how ranchers perceive wildlife management and assistance programs. It is also important that conservation agency personnel working with these ranchers are able to assess rancher perceptions of wildlife management accurately so they can tailor programs that meet rancher needs and foster strong working and interpersonal relationships. We surveyed 1,634 ranchers to understand their perceptions of wildlife benefits and problems, attitudes toward wildlife, and likeliness to participate in financial and technical assistance programs. We also surveyed 52 natural resource-agency personnel regarding their perceptions of ranchers on similar topics, to allow for direct comparison of responses. Rancher and agency responses were similar for many wildlife benefits and attitudes toward wildlife, yet agency personnel overestimated rancher perceptions of wildlife problems and the economic benefits of wildlife enterprises. We suggest ways conservation agencies can improve current assistance programs for cattle ranchers based on both rancher and agency employee perceptions of wildlife management. This includes emphasizing programs that feature preferred species and better integrating wildlife management with routine cattle operations.

This study focuses on the mixed-ownership reform of state-owned enterprises in an industry chain. By constructing an oligopoly model considering the proportion of state-owned shares and product differentiation, this study examines the impacts of the balance of state-owned shares and product differentiation in four scenarios, and analyzes the proportion of state-owned shares to maximize the social welfare of the industry chain. The results reveal a synergistic relationship between the balance of state-owned shares and product differentiation. The equilibrium results vary in different industry chain links and competition modes. The implementation of mixed ownership by upstream enterprises will help improve the overall efficiency of the industry chain. Complete nationalization may be optimal and an upstream monopoly can be realized under certain conditions.

This paper explores the interaction between the energy costs/GDP ratio, energy prices, energy efficiency, “quality of energy’’, and economic growth. The relationships between the first three were formulated by the author back in 2007 in the form of three laws of energy transitions. The paper provides additional empirical evidence and theoretical support to these laws and looks into their implications for economic growth and climate mitigation policies. It argues for launching effective energy costs accounting at the national level to support such policies. It also argues that escalation of energy prices driven only by the growing share of higher quality energy resources does not impede, but stimulates economic growth. The paper shows, that improving energy efficiency results in the removal of the ‘limits of growth’ – affordability, resource and environmental limitations; but as it faces the ‘limits of change’, the trade-off between maximizing economic growth and minimizing GHG emissions is inevitable.

Information is critical for environmental governance. The rise of digital mapping has the potential to advance private-land conservation by assisting with conservation planning, monitoring, evaluation, and accountability. However, privacy concerns from private landowners and the capacity of conservation entities can influence efforts to track spatial data. We examine public access to geospatial data on conserved private lands and the reasons data are available or unavailable. We conduct a qualitative comparative case study based on analysis of maps, documents, and interviews. We compare four conservation programs involving different conservation tools: conservation easements (the growing but incomplete National Conservation Easement Database), regulatory mitigation (gaps in tracking U.S. Fish and Wildlife Service’s endangered species habitat mitigation), contract payments (lack of spatial data on U.S. Department of Agriculture’s Conservation Reserve Program due to Farm Bill restrictions), and property-tax incentives (online mapping of Wisconsin’s managed forest tax program). These cases illuminate the capacity and privacy reasons for current incomplete or inaccessible spatial data and the politics of mapping private land. If geospatial data are to contribute fully to planning, evaluation, and accountability, we recommend improving information system capacity, enhancing learning networks, and reducing legal and administrative barriers to information access, while balancing the right to information and the right to privacy.

Abstract The largest concentration of state-level forest cost-share programs in the United States can be found in the southern states. Since the inception of the first programs in the 1970s, the state-level forest cost-share programs in the US South have acted as models for the rest of the country. Cost-share programs compensate landowners through direct reimbursements to address barriers such as limited owner capital and cash flow in the initial years of investment. Through a review of the literature and progress reports from southern state forestry agencies, we qualitatively assessed state-level cost-share programs and their status in the southern states. We identified the common themes in the literature related to cost-share programs: market, nonmarket, and landowners’ perceptions and knowledge. Many of the programs enacted between the 1970s and 1980s aimed to ensure a sustainable timber supply, a market good, from private forestlands. A few of the programs enacted more recently compensate landowners for nonmarket benefits such as forest health or soil and water conservation. Two of the nine available programs are practically inactive in recent years because of a lack of funding. We discuss current prospects regarding funding, partnerships, and broadening the focus of incentives to cover forest-based ecosystem services. Study Implications Regionally, cost-share programs in the US South differ in eligibility criteria, funding source and status, and resource management objectives. The majority of state-level cost-share programs in the US South were enacted 30 to 50 years ago. The first cost-share programs were designed to support a continued timber supply from private forestlands, but a few recent programs have expanded their objectives to protect forest health and soil and water quality. Forest-based ecosystem service markets, specifically reforestation to capture atmospheric carbon dioxide and provide clean air and water, have become more prevalent in recent years. Funding for forest commodity incentive programs is a continual challenge. New funding sources and new programs are crucial to meet demands for incentives for landowners to provide both timber and ecosystem services outputs.

This study used panel data models with spatial error correlation to analyze private tree planting in the US South from 1955 to 2003. Controlling for statewide, fixed effects allows us to disentangle the effect of spatial interaction from that of state heterogeneity and omitted variables. The results show that there is significant spatial interdependence among the southern states in private tree planting. Harvest rates, softwood sawtimber price, income levels, cost of capital, and federal and state cost-share programs are important factors affecting nonindustrial private (nonindustrial private forestland [NIPF]) tree planting. Harvest rates, softwood sawtimber and pulpwood prices, and planting cost are important factors affecting forest industry (FI) tree planting. Finally, the Soil Bank Program has had substitution effects on southern FI tree planting and nonsubsidized NIPF tree planting.

Development of energy policy is often informed by economic considerations via aggregate production functions (APFs). We identify a theory-to-policy process involving APFs comprised of six steps: (1) selecting a theoretical energy-economy framework; (2) formulating modeling approaches; (3) econometrically fitting an APF to historical economic and energy data; (4) comparing and evaluating modeling approaches; (5) interpreting the economy; and (6) formulating energy and economic policy. We find that choices made in Steps 1–4 can lead to very different interpretations of the economy (Step 5) and policies (Step 6). To investigate these effects, we use empirical data (Portugal and UK) and the Constant Elasticity of Substitution (CES) APF to evaluate four modeling choices: (a) rejecting (or not) the cost-share principle; (b) including (or not) energy; (c) quality-adjusting (or not) factors of production; and (d) CES nesting structure. Thereafter, we discuss two revealing examples for which different upstream modeling choices lead to very different policies. In the first example, the (kl)e nesting structure implies significant investment in energy, while other nesting structures suggest otherwise. In the second example, unadjusted factors of production suggest balanced investment in labor and energy, while quality-adjusting suggests significant investment in labor over energy. Divergent outcomes provide cautionary tales for policymakers: greater understanding of upstream modeling choices and their downstream implications is needed.
