We utilise several asset pricing models that allow for discontinuities in the returns and volatility time series in order toobtain estimates of Value-at-Risk (VaR). The first class of model that we use mixes a continuous diffusion processwith discrete jumps at random points in time (Poisson Jump...

The mean residual life function (mrlf) of a subject is defined as the expected remaining (residual) lifetime of the subject given that the subject has survived up to a given time point. It is well known that under mild regularity conditions, an mrlf determines the probability distribution...

The objective of this paper is to explore how the demand of germplasm held by CGIAR genebanks changed over time in order to assess the possible influence of the 1994 In Trust Agreements on germplasm demand. The proposed theoretic model motivates the realistic hypothesis that the consequences of...

Most existing empirical evidence on the impact of profit taxationon multinational firm activity is based on cross-country data. One majordrawback of such data is that countries differ not only with regardto taxes but along other dimensions which might be hard to captureby means of observable...

This research assesses the performance of over-dispersed Poisson regression model and negative binomial model with count data. It examines the association between price plan features of mobile phone services and the number of people who adopt the plan. Mobile service data is used to estimate the...
