We generalize the concept of the natural rate of interest (Laubach and Williams, 2003; Woodford, 2003) by defining and estimating the natural yield curve (NYC) – the term structure of natural interest rates. Our motivation stems i.a. from the observation that at times when central banks attempt to directly affect long-term interest rates (e.g. via quantitative easing) the gap between the short-term real and natural rate is no more a good indicator of the monetary policy stance. We estimate the NYC on US data, document its main properties and show i.a. that in the period 2008 to 2011 the NYC allows to better capture the US monetary policy stance than the short-term natural rate. 相似文献

Selection of a Representative Value Function for Robust Ordinal Regression in Group Decision Making 总被引：1，自引：1，他引：1
In this paper, we introduce the concept of a representative value function in a group decision context. We extend recently proposed methods UTAGMS-GROUP and UTADISGMS-GROUP with selection of a compromise and collective preference model which aggregates preferences of several decision makers (DMs) and represents all instances of preference models compatible with preference information elicited from DMs. The representative value function is built on results of robust ordinal regression, so its representativeness can be interpreted in terms of robustness concern. We propose a few procedures designed for multiple criteria ranking, choice, and sorting problems. The use of these procedures is conditioned by both satisfying different degrees of consistency of the preference information provided by all DMs, as well as by some properties of particular decision making situations. The representative value function is intended to help the DMs to understand the robust results, and to provide them with a compromise result in case of conflict between the DMs. 相似文献

In this article, we test to what extent the food aid granted by the U.S. during the Cold War was strategically motivated and used to promote U.S. interests. Using the data for the period 1971–1990, we investigate whether U.S. wheat aid had an effect on recipient countries’ total import of American products. The evidence we provide suggests a positive and robust relationship and thus it is consistent with the argument that U.S. food aid helped to create larger markets for U.S. producers. 相似文献

We consider the portfolio choice problem for a long‐run investor in a general continuous semimartingale model. We combine the decision criterion of pathwise growth optimality with a flexible specification of attitude toward risk, encoded by a linear drawdown constraint imposed on admissible wealth processes. We define the constrained numéraire property through the notion of expected relative return and prove that drawdown‐constrained numéraire portfolio exists and is unique, but may depend on the investment horizon. However, when sampled at the times of its maximum and asymptotically as the time‐horizon becomes distant, the drawdown‐constrained numéraire portfolio is given explicitly through a model‐independent transformation of the unconstrained numéraire portfolio. The asymptotically growth‐optimal strategy is obtained as limit of numéraire strategies on finite horizons. 相似文献

Rising gas production from nonconventional deposits in North America and the possibility of growth in the rest of the world pose a serious challenge to Russian energy interests. Although Russia has the largest proven gas reserves and is the number one exporter of fossil fuels, its position as a dominant gas supplier to the European Union (EU) is diminishing. This article examines the main problems of Russia's gas sector in the context of the shale gas revolution and the liberalization of the EU gas market. The article also analyses the perspectives of Russia's energy relations with EU countries and formulates some recommendations for them. 相似文献

This study measures hypothetical bias in CVM-based estimates of willingness to support a forest protection and restoration program in Poland. It does so in two parallel ways: within- and between-subjects. To this end, participants are asked to vote in a referendum on an NGO-led reforestation project for various per-capita cost levels. They do so either directly or, as a surprise continuation, after a hypothetical analogue. Both methods deliver a similar (and substantial) level of hypothetical bias – it is slightly higher, but not significantly so, in the between-subject comparison. This suggests that hypothetical bias in this context is not primarily driven by such factors as consistency seeking or impression management. 相似文献
