Before reporting the empirical results, a few discussions on the regression design are in order. First, although the regressions measure the contemporaneous responses of insurers' portfolios to the term structure factor changes over a one-year period, the measured re- sponses could well capture ...
This is a set of simultaneous first-order nonlinear ordinary differential equations. The solution of these equations first requires the determination of the constants α, β, γ, and δ, and the specification of boundary conditions. The latter could be either initial or final conditions. In popula...

3.1 Notation for ODEs Before we proceed to the further development of ODE integration algorithms, we will introduce some notation that is relatively standard in the field. A single first order ODE will be written as (3.1)dy/dt=f(y,t) with the initial condition (3.2)y(t0)=y0 Note that ...
First-Order Derivative The first order derivatives tell about the direction of the function whether the function is increasing or decreasing. The first derivative math or first-order derivative can be interpreted as an instantaneous rate of change. It can also be predicted from the slope of the ...
set of Fourier coefficients, therefore they are independent. In the language of circuit theory, by noticing thatf(x) andg(x) correspond with the characteristic curves of a resistive and a reactive element, respectively, the argument in the last sentence means that in a given first order ...
(X,≤X), meaningx≤Xywheneverx,y∈Xandx≤y. To facilitate notation we will denote≤Xsimply by≤when no confusion can arise. A quasiorder (often called preorder, in particular in the economic literature) is a reflexive and transitive relation. If we denote a quasiorder by≾thena≾...
