This paper analyses the effects of the recent global economic crisis upon sovereign wealth funds (SWFs). Since mid-2007, SWFs have experienced significant portfolio losses, a decline in fund inflows, and enhanced scrutiny from their own governments. SWFs have been utilised for sovereign stabilisation programs and have helped finance troubled Western banks. SWFs and the IMF have also created a set of best practices known as the Santiago Principles. From these developments, many SWFs have moved to relatively shorter investment time horizons and more liquid holdings, revamped their transparency and management, experienced a temporary improvement in their images, begun to hold controlling stakes in major Western corporations, and have improved their coordination with institutional investors and other SWFs. Going forward, these changes, alongside the relatively strong post-crisis asset position held by SWFs in comparison to other asset vehicles, make SWFs well-positioned to play an even more prominent role in global finance.  相似文献

In India, cane is processed into sugar by cooperatives, public enterprises, and private (for‐profit) firms. The Indian government sets a unique floor price for each processor that is increasing in the firm's effectiveness in converting cane into sugar. The floor price binds for public and private firms but not for cooperatives, which rebate profits to members. We argue that this price floor policy creates a disincentive for private and public firms to be technically efficient in converting cane to sugar. In support of this hypothesis an analysis of 593 Indian sugar factories from 1992 to 2007 reveals statistically significant differences in technical efficiency, with cooperatives being the most efficient and public firms least efficient. We estimate welfare losses due to the technical inefficiency attributable to the price‐floor policy and argue that it can be eliminated by enacting policy to base price floors upon quality of the cane input received by a factory.  相似文献

In the context of the Partnership Agreements between the European Union (EU) and the African, Caribbean, and Pacific countries, this study estimates ad valorem tariff equivalents of European food safety standards on imports of key horticultural and fish products from Kenya, Tanzania, Uganda, and Zambia. The study uses an extension of the price‐wedge method to account for imperfect substitution and factor endowment in monopolistic competition. The estimated tariff equivalents are 55% and 98% for imports of fresh peas from Zambia to the Netherlands and the U.K., respectively. They range from 39% to 64% for imports of green beans and avocados from Kenya and from 63% to 270% for imports of frozen fish fillets in EU countries from the East African Community. We also observe large variations in tariff equivalents for the horticultural and fish products over time and EU importing countries.  相似文献

Challenges for land system science   总被引:3,自引:0,他引:3  
While considerable progress has been made in understanding land use change, land system science continues to face a number of grand challenges. This paper discusses these challenges with a focus on empirical land system studies, land system modelling and the analysis of future visions of land system change. Contemporary landscapes are contingent outcomes of past and present patterns, processes and decisions. Thus, empirical analysis of past and present land-use change has an important role in providing insights into the socio-economic and ecological processes that shape land use transitions. This is especially important with respect to gradual versus rapid land system dynamics and in understanding changes in land use intensity. Combining the strengths of empirical analysis with multi-scale modelling will lead to new insights into the processes driving land system change. New modelling methods that combine complex systems thinking at a local level with macro-level economic analysis of the land system would reconcile the multi-scale dynamics currently encapsulated in bottom-up and top-down modelling approaches. Developments in land use futures analysis could focus on integrating explorative scenarios that reflect possible outcomes with normative visions that identify desired outcomes. Such an approach would benefit from the broad and in-depth involvement of stakeholders in order to link scientific findings to political and societal decision-making culminating in a set of key choices and consequences. Land system models have an important role in supporting future land use policy, but model outputs require scientific interpretation rather than being presented as predictions. The future of land system science is strongly dependent on the research community's capacity to bring together the elements of research discussed in the paper, via empirical data collection and analysis of observed processes, computer simulation across scale levels and futures analysis of alternative, normative visions through stakeholder engagement.  相似文献

The European COST Action E45 on European Forest Externalities (EUROFOREX) participants developed a set of good practice guidelines for the non-market valuation of forests, elaborating on stated and revealed preference methodologies, as well as benefit transfer and meta-analytical procedures. This article presents a summary of the guidelines.  相似文献

In Sub-Saharan Africa (SSA), inland export transport costs and time delays are much higher for landlocked countries, vary substantially between different geographic corridors, and exhibit substantial uncertainty. Unit costs and costs of time for land transport of exports are high for many agricultural products relative to metals and other high-value products. We illustrate systemic uncertainty in land and maritime transport for exporting by use of simulation. Relationships among uncertainty, infrastructure quality, and other features of logistics systems are highly non-linear, and can be potentially used to identify priorities for trade facilitation.  相似文献

This paper examines the effects of the Economic and Monetary Union on demand for foreign reserves. The traditional theory on demand for international reserves assigns a pivotal role to imports. However, in a currency union part of imports are settled in the common currency, leaving no incentive for keeping foreign reserves. Moreover, the pooling of the demand for reserves in the currency union and an increasing role of a currency as an international reserve currency may also influence, among other things, the union demand for reserves. Based on estimated demand functions for reserves it is shown that the Economic and Monetary Union has reduced the demand for reserves substantially. It is argued that an enlargement with new member countries of the European Union will result in further savings of reserves. A simple calculation at the end of the paper illustrates the welfare gain associated with the reduced need of reserves in the Economic and Monetary Union.  相似文献

Funded social security programs are particularly vulnerable to economic and financial market shocks. As a consequence of the recent crisis, a large fraction of the Dutch pension funds had to submit restoration plans for the recovery of their buffers. Such plans will have to rely primarily on a mix of reduced benefit indexation and increased pension contributions. Hence, a discussion has emerged whether indexation should be differentiated across the various groups of participants in a pension fund. We investigate this issue numerically, developing an applied many-generation small open-economy OLG model with heterogeneous agents. The pension system consists of a first-pillar PAYG component and a second pillar with a pension fund. In our stochastic simulations, we hit the economy with a variety of unexpected demographic, economic and financial shocks. We compare uniform indexation of pension rights across all fund participants with alternatives such as status-contingent indexation in which pensions are protected against price inflation. While the aggregate welfare consequences are small, group-specific consequences are more substantial with the workers and future born losing and retirees benefitting from a shift away from uniform indexation. The exception is a scheme which links indexation directly to the fund’s asset performance. Under this scheme the retired benefit without other groups losing. The welfare effects are primarily the result of systematic welfare redistributions rather than of shifts in the benefits of risk sharing. Contribution rates always have to rise substantially from their initial levels to maintain the system’s sustainability. An increase in the retirement age that leaves existing pension rights untouched does little to avoid this rise with its adverse labour market consequences.  相似文献
