This paper compares the performance of three alternative models in forecasting housing supply in the Irish Republic. The results highlight key behavioural issues in the dynamics of housing supply that the OLS and VAR models fail to adequately capture due to the inclusion of fundamental variables in their specification. The behaviour of developers in delaying projects means that housing supply c...

Within the Internal Ratings-Based (IRB) approach of Basel II it is assumed that idiosyncratic risk has been fully diversified away. The impact of undiversified idiosyncratic risk on portfolio Value-at-Risk can be quantified via a granularity adjustment (GA). We provide an analytic formula for the GA in an extended singlefactor CreditRisk setting incorporating double default effects. It accounts...

We discuss linear regression approaches to the estimation of law-invariant conditional risk measures. Two estimation procedures are considered and compared; one is based on residual analysis of the standard least-squares method, and the other is in the spirit of the M-estimation approach used in robust statistics. In particular, value-at-risk and average valueat-risk measures are discussed in d...

We give a simple proof for Kaneko’s theorem which gives a su2cient and necessary condition for the existence of vertex disjoint paths in a graph, each of length at least two, that altogether cover all vertices of the original graph. Moreover we generalize this theorem and give a formula for the maximum number of vertices that can be covered by such a path system. c © 2004 Elsevier B.V. All righ...

Analysis of images involving humans is of significant interest in computer vision because problems such as detection, modeling, recognition, and tracking are fundamental to model interactions between people and understand highlevel activities. Visual information contained in images is generally represented using feature descriptors. Many general classes of descriptors have been proposed focusin...

We prove that if G is a graph of order at least 5k with k ≥ 2 and the minimum degree of G is at least 3k then G contains k disjoint cycles of length at least 5. This supports the conjecture by Wang [Australas. J. Combin. 54 (2012), 59–84]: if G is a graph of order at least (2d+1)k and the minimum degree of G is at least (d+1)k with k ≥ 2 then G contains k disjoint cycles of length at least 2d+ 1.
