When Is Efficiency Separable from Distribution in the Provision of Club Goods?

Using the homogeneous of degree zero inverse congestion (“quality”) function employed most frequently in the literature, we characterise completely the families of utility functions which are then necessary and sufficient for break-even utilitarian welfare maximising provision of club goods with self-selection to be separable from distribution. Two types of separation—involving, alternatively (a) the price and quality; (b) the price, quality, facility size and total utilisation—are considered. When separation is possible, utility functions and optimal decisions take simple, intuitive forms. Our results extend the scope of separation results previously obtained only for pure public goods.

The future of the uplands

Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible.     

Wireless digital advertising: nature and implications

The convergence of the Internet and wireless telecommunications in the late 1990s has opened the way for a plethora of data services for the mobile handset user. One potential area of development is wireless advertising. The personal, always-at-hand nature of devices, along with the ability to assess context dependence (e.g. time and location), presents a rich platform for wireless advertising. Using a range of wireless platforms, operators will be able to offer very different advertising services that go beyond those of the wired Internet. The purpose of this paper is to review the emerging technologies, applications and research issues associated with wireless advertising. It concludes with some predictions on the future role of wireless advertising.

On the determinants of yield spreads between mortgage pass-through and Treasury securities

Yield spreads between mortgage pass-through and U.S. Treasury securities may reflect differences in taxation, phenomena affecting relative supply and demand, and compensation for default, call, and marketability risks on mortgage instruments. Our research empirically models differences in yields between pass-throughs and comparable-maturity Treasuries. We find that interest-rate volatility and the term structure of rates, factors often cited in the mortgage pricing literature as affecting the mortgage call premium, are the primary determinants of movements in these spreads. Moreover, these effects have grown in importance in recent years as exercise of the prepayment option has increased. We also find evidence that liquidity and credit concerns affect the pricing of pass-through securities.
