Comparison of MSACD models
(2003)
We propose a new framework for modelling time dependence in duration processes on financial markets. The well known autoregressive conditional duration (ACD) approach introduced by Engle and Russell (1998) will be extended in a way that allows the conditional expectation of the duration process to depend on an unobservable stochastic process which is modelled via a Markov chain. The Markov switching ACD model (MSACD) is a very flexible tool for description and forecasting of financial duration processes. In addition, the introduction of an unobservable, discrete valued regime variable can be justified in the light of recent market microstructure theories. In an empirical application we show that the MSACD approach is able to capture several specific characteristics of inter trade durations while alternative ACD models fail. JEL classification: C22, C25, C41, G14

The Markov switching ACD model (MSACD) is a flexible tool for description of financial duration processes. The introduction of a latent information regime variable can be justified in the light of recent market microstructure theories.

The Arab-Israeli wars

The European Strategy on Invasive Alien Species T-PWS(2002) 8 mandates intensified research by member nations on invasive species. This research will not be restricted solely to the biology and remediation of invasive species, but will also evaluate their adverse health effects and economic impact. Previous studies of these issues have only been carried out in the Unites States of America, or in a limited, regional manner. Consequently, 20 plant and animal species from various problem areas (species which pose a threat to public health; losses to agriculture, fisheries, and forestry; damage to public roads and waterways; costs associated with the protection of native species threatened by non-native species as mandated by Recommendation 77 of the Bern Convention were assessed in Germany nation-wide. The accruing costs were sorted into 3 categories: a) direct economic losses, such as those caused by destructive pest species; b) ecological costs, in the form of extra care and protection of native taxa, biotopes, or ecosystems threatened by invasive species; c) costs of measures to combat invasive species. Because of the nature of available data, as well as the different biology and ecology of the invasive species, each had to be treated individually, and the associated costs vary greatly from species to species. Moreover, not all of the species investigated cause economic losses. Accordingly, a nuanced approach to alien species is essential. Cost assessment of losses deriving from ecological damage was only possible in a few cases. Ongoing, multi-year studies incorporating cost/benefit analysis will be necessary to resolve remaining issues.
In this paper I discuss the properties of particle verbs in light of a proposal about syntactic projection. In section 2 I suggest that projection involves functional structure in two important ways: (i) only functional phrases can be complements, and (ii) lexical heads that take complements and project must be inflected. In section 3, I show that the structure of particle verbs is not uniform with respect to (i) and (ii). On the one hand, a particle always combines with an inflected verb; in this respect, particle verbs look like verb-complement constructions. On the other hand, the particle is not a functional phrase and therefore is not a proper complement, which makes the combination of the particle and the verb look more like a morphologically complex verb. I argue that syntactic rules can in fact interpret the node dominating the particle and the verb as a projection and as a complex head. In section 4, I show that many of the characteristic properties of particle verbs in the Germanic languages follow from the fact that they are structural hybrids.
