The purpose of this note is to correct an error in Baltrunas et al. (2004) [1], and to give a more detailed argument to a formula whose validity has been questioned over the years. These details close a gap in the proof of Theorem 4.1 as originally stated, the validity of which is...

In this paper we establish a local precise large deviation result for sums Sn, n=1,2,... of independent and identically distributed random variables X1,X2,... with O-regularly varying densities f. The asymptotic behavior of the probability is comparable, for fixed T, with quantities or...

type="main" xml:id="jscm12070-abs-0001" <p>We introduce a new type of critical supplier—the nexus supplier—that becomes evident when we consider suppliers from a network perspective. The extant literature focuses on the importance of strategic suppliers and identifies strategic suppliers as...</p>

With motivation from Tang et al. (2011), in this paper we consider a tractable multivariate risk structure which includes the Sarmanov dependence structure as a special case. We derive several asymptotic results for both the sum and the product of such risk and then present three applications...

To achieve agricultural sustainability, basic land planning would allocate more areas for specific land uses with high ecosystem service values. However, this has always failed because of its low economic interest. Paying farmers would be effective for its implementation. To overcome previous...

This paper deals with the asymptotic behavior for the tail probability of randomly weighted sums of subexponential random variables under a dependence structure, where the random weights and the corresponding summands are dependent.

Let {Sn:n≥0} be a random walk with negative drift and τ(x) be the first time when the random walk crosses a given level x≥0. This paper focuses on random walks with non-convolution equivalent increments. For this random walk, the uniform asymptotics of P(Sτ(x)−xy,τ(x)∞), as x→∞,...
