Although it had a a lower income level than India in 1980, China's 2006 per capita gross domestic product stands more than twice that of India's. This paper investigates the role of the business environment in explaining China's productivity advantage using recent firm-level survey data. The...

This paper investigates the compound Poisson risk model with debit interest. The model assumes that the company is allowed to borrow at some debit interest rate when the surplus turns negative. We obtain the Laplace-Stieltjes transform (LST) of the hitting time of the risk process with constant...

In this paper we investigate the distribution function and the Laplace-Stieltjes Transform(L-S-T) of the first [beta] point of the surplus process {U(t),t[greater-or-equal, slanted]0} using its strong Markov property and the theory of renewal measure. We find the distribution function of in some...

We consider scheduling for heterogeneous server systems, where tasks arrive according to a Poisson process, with their processing requirements following a discrete distribution with finite support. For a system with a dispatcher and several heterogeneous servers, we propose an optimized...
