An assessment of the economic and environmental potential of biomass production in an agricultural region

The establishment of deep-rooted perennial species and their processing for biomass-based products such as renewable energy can have benefits for both local and global scale environmental objectives. In this study, we assess the potential economic viability of biomass production in the South Australian River Murray Corridor and quantify the resultant benefits for local and global scale environmental objectives. We model the spatial distribution of economically viable biomass production in a Geographic Information System and quantify the model sensitivity and uncertainty using Monte Carlo analysis. The total potentially viable area for biomass production under the Most Likely Scenario is 360,728 ha (57.7% of the dryland agricultural area), producing over 3 million tonnes of green biomass per annum, with a total Net Present Value over 100 years of A$ 88 million. The salinity in the River Murray could be reduced by 2.65 EC (μS/cm) over a 100-year timeframe, and over 96,000 ha of land with high wind erosion potential could be stabilised over a much shorter period. With sufficient generating capacity, our Most Likely Scenario suggests that economically viable biomass production could reduce carbon emissions by over 1.7 million tonnes per annum through the production of renewable energy and a reduced reliance on coal-based electricity generation. Our analyses suggest that biomass production is a potentially viable alternative agricultural system that can have substantial local scale environmental benefits with complimentary global scale benefits for climate change mitigation.     

Incentives and disincentives for diversified agroforestry systems from different actors’ perspectives in Bolivia

Even though diversified agroforestry systems can provide sustainable livelihoods and a resilient production of different goods, adoption remains limited in Bolivia. We examine major obstacles to agroforestry adoption and possible incentives proposed by farmers and civil-society organizations, and relate them to governance and international mechanisms that might play a role in agroforestry adoption. Market access for produce from diversified agroforestry remains difficult, as does its processing and transport. Moreover, farmers have difficulties in achieving the quantities and homogenous quality demanded by markets in the major cities. But most importantly, farmers and civil-society organizations saw little government support, although ‘ecological production in harmony with Mother Earth’ is prescribed by law and the constitution. Agroforestry farmers needed support most urgently in the initial phase, when investment costs are high and returns low. They suggested affordable credits, subsidies for diversified farming systems, and insurance against fire. We identified important albeit small steps towards developing markets for agroforestry products, but government support – mostly in the form of diesel subsidies, materials, and infrastructure – mainly benefitted large-scale monocultures and cattle ranching. In response to this, interviewees opted for strengthening farmers’ organizations, for demanding support with the help of civil-society organizations, and for disseminating best practices.

A Graphical Approach to the Standard Principal-Agent Model

An obstacle to the teaching of principal-agent theory is the technical complexity and intractability of the general model. Even in academic studies strong assumptions are often imposed so as to derive an analytical solution. The author describes a graphical approach to the standard principal-agent model. Characterizing equilibrium in the contract space defined by the incentive parameter and insurance component of pay under a linear contract, this approach provides a simple and intuitive method for analyzing the principal-agent problem, which can be easily understood by students of economics with basic knowledge of algebra and differentiation. The approach has shown to be convenient and rich for comparative statics analyses.     

Strategic R&D investment,competitive toughness and growth

We show, within a single industry, the possibility that R&D‐investment is non‐monotonically related to competitive toughness: increasing when competition is soft and decreasing when competition is tough. This possibility results from the combination of a Schumpeterian markup squeezing effect discouraging innovation, and a concentration effect spurring innovators. It is obtained in a sectoral model where the number of innovators is random and where non‐successful investors may remain productive. The result is extended to a multisectoral stochastic endogenous growth model with overlapping generations of consumers and firms, the number of which is endogenously determined in the capital market.     

South Africa's economics of education: A stocktaking and an agenda for the way forward

This paper reviews some of the existing economics of education literature from the perspective of South Africa's education policymaking needs. It also puts forward a suggested research agenda for future work. The review is arranged according to five areas of research: rates of return, production functions, teacher incentives, benefit incidence analysis and cross-country comparisons. Production functions, especially if translated to cost-effectiveness models, can point to important policy solutions. Teacher incentives is a policy area that is in need of a better theoretical and empirical basis. Rates of return are difficult for policymakers to interpret, but suggest a need for a qualification below the Grade 12 level. While benefit incidence analysis can demonstrate large improvements in the equity of public financing, cross-country comparisons reveal that not only is the distribution of schooling outcomes particularly unequal, on average it is well below what the country's level of development would predict.     

商业银行股权激励的特殊意义与现实问题分析

银行业普遍存在的管制,使银行面临着有限的控制权市场和接管威胁,从而大大降低了市场约束银行管理者的能力,因此对银行而言,通过股权激励机制协调股东和管理者的利益、降低代理成本显得尤为重要.我国商业银行实施股权激励不应盲目照搬西方国家的范例,应慎重选择股权激励的实施范围,目前最好只局限在高级管理人员,通过对股权激励机制的合理设计来充分发挥其长期激励效应,切不可盲目扩大激励范围,将股权激励演变成一种新的福利措施.应尽快建立起以经济资本为核心的业绩考核体系,在经济资本的约束下实现业务发展模式和盈利模式的转变.股权激励机制的有效实施离不开完善的银行治理结构.     

股权激励对上市公司的影响及投资策略分析

本文探讨了我国上市公司实施股权激励的环境条件，分析了股权激励对管理层、股东影响的内在机制，分析了实施股权激励对上市公司价值和业绩的影响。对股权激励类上市公司上涨因素的定量化分析显示，其上涨与公司现有的各项财务指标没有必然联系，而与公司的市场地位、行业发展趋势和关联交易之间存在明显的关系。本文认为，我国上市公司已基本具备实施股权激励的环境条件，实施股权激励有利于解决管理层和股东利益一致性问题，通过价值转移和价值创造，持续、有效地促进上市公司价值和业绩的提高，从而有效推动上市公司股价的上升，给投资者以强有力的信心和巨大的投资机会。     

Employee Perceptions of Award and Incentive Programs

Abstract

Employee award and incentive programs have become standard practice in the business world and in many nonprofit organizations. A study was conducted to measure employee beliefs about meeting management's objectives and employee satisfaction with award/incentive programs. It was found that employee motivation-in terms of liking awards, willingness to encourage others, and willingness to work hard for awards-was the most important factor contributing to employee satisfaction with the programs and employee perception that management's objectives were satisfied by these programs.     

Increasing Charitable Giving: What Can We Learn from Economics?*

There is growing policy interest in charitable giving in the UK. As part of its Big Society agenda, the current government is keen to encourage a higher level of donations, highlighting new technologies, new social norms and tax incentives as potential mechanisms for raising giving. In the 2012 Budget, however, the Chancellor also proposed limiting tax relief on donations to £50,000, sparking an intense discussion about the effectiveness and desirability of tax incentives for major donors. This paper brings together recent evidence relevant to the ongoing policy debates.
