Pricing default swaps: Empirical evidence 总被引:1,自引:0,他引:1
In this paper we compare market prices of credit default swaps with model prices. We show that a simple reduced form model outperforms directly comparing bonds' credit spreads to default swap premiums. We find that the model yields unbiased premium estimates for default swaps on investment grade issuers, but only if we use swap or repo rates as proxy for default-free interest rates. This indicates that the government curve is no longer seen as the reference default-free curve. We also show that the model is relatively insensitive to the value of the assumed recovery rate. 相似文献

We compare the manipulability of different choice rules by considering the number of manipulable profiles. We establish the minimal number of such profiles for tops-only, anonymous, and surjective choice rules, and show that this number is attained by unanimity rules with status quo. 相似文献

This paper will present the analysis of data over 3 years (1998, 1999, and 2000) on the satisfaction of flex workers in the
context of a flex company’s service excellence programme, as an example of the use of measurements in relation to the change
process. The important issues related to the specific data of the flex workers’ satisfaction surveys are: (a) the relationships
between perceived satisfaction of flex workers and possible behavioural consequences, like making complaints and making use
of other flex companies; (b) the stability of factor constructs over time that identify the major dimensions of satisfaction
of flex workers; and (c) the satisfaction dynamics over time. 相似文献

It is broadly expected that customer satisfaction (CS) influences customer revenues (CR), but there is little evidence for the corresponding hypothesis. If CS influences CR, there must be a relation between CS at time t?=?0 and CR at time t?>?0. We developed a statistical model representing this relation, which we tested in a longitudinal study using person-level data (N?=?1682) from a Dutch retail bank. We found that CS had a positive effect on CR with 1-year and 2-year time lags. These results support the hypothesis that CS influences CR. 相似文献

This article examines the impact of participants’ age distribution on the asset allocation of Dutch pension funds, using a unique data set of pension fund investment plans for 2007. Theory predicts a negative effect of age on (strategic) equity exposures. We observe that a 1‐year higher average age in active participants leads to a significant and robust reduction of the strategic equity exposure by around 0.5 percentage point. Larger pension funds show a stronger age‐equity exposure effect. The average age of active participants influences investment behavior more strongly than the average age of all participants, which is plausible as retirees no longer possess any human capital. 相似文献

In a model with finitely many agents who have single-dipped Euclidean preferences on a polytope in the Euclidean plane, a rule assigns to each profile of reported dips a point of the polytope. A point $x$ of the polytope is called single-best if there is a point $y$ of the polytope such that $x$ is the unique point of the polytope at maximal distance from $y$ . It is proved that if the polytope does not have either exactly two single-best points or exactly four single-best points which form the vertices of a rectangle, then any Pareto optimal and strategy-proof rule is dictatorial. If the polytope has exactly two single-best points, then there are non-dictatorial strategy-proof and Pareto optimal rules, which can be described by committee voting (simple games) between the two single-best points. This also holds if there are exactly four single-best points which form the vertices of a rectangle, but in that case, we limit ourselves to describing an example of such a rule. The framework under consideration models situations where public bads such as garbage dumping grounds or nuclear plants have to be located within a confined region. 相似文献
