Asymptotic results are obtained for several conditional measures of association. The chosen random variables are the first two order statistics and the total sum within a random sum. Many of the results have confirmed the “one-jump” property of the risk model. Non-trivial limits are...

Consider a renewal risk model in which claim sizes and inter-arrival times correspondingly form a sequence of independent and identically distributed random pairs, with each pair obeying a dependence structure described via the conditional distribution of the inter-arrival time given the...

Consider the randomly weighted sums , n=1,2,..., where {Xk,k=1,2,...} is a sequence of independent real-valued random variables with common distribution F, whose right tail is regularly varying with exponent -[alpha]0, and {[theta]k,k=1,2,...} is a sequence of positive random variables,...

The switching of health insurance plans and health care utilization are potentially correlated with both observable and unobservable information. This paper presents a two-period model of health care utilization, and attempts to account for unobserved heterogeneity that simultaneously affects...

In this paper, we used the production function method and the Van Norden method to estimate China's output gap (and potential output) from 1985 to 2009 year,and comparise the two methods. The results showed that: (1) the results of different methods are basically consistent with our economic...

Since reform and open to the outside world, foxtail millet planting area in Hebei Province has constantly reduced, and its planting region has changed from the whole province into some regions, with obvious changes. In this paper, by using qualitative and quantitative approaches like chart...
