若集合X上的映射ρ:X×X→[0,∞)满足:(1)ρ(x,y)≥0,ρ(x,x)=0;(2)ρ(x,z)≤ρ(x,y)+ρ(y,z),∀x,y,z∈X;则称ρ是非对称伪度量,(X,ρ)为非对称伪度量空间.若ρ还满足,(3)ρ(x,y)=ρ(y,x)=0⇒x=y,∀x,y∈X;则称ρ是非对称度量,(X,ρ)为非对称度量空间.非对称度量ρ的共轭度量记为,其中(x,y)=ρ(y,x),x,y∈X.ρs(x,y)=max{ρ(x,y),(x,y)}是X上的度量当且仅当ρ是X上的非对称度量,x,y∈X.例1 在实数集R上定义函数ρ(x,y)=max{x-y,0},则(R,ρ)是非对称度量,容易知道ρs(x,y)= |x-y|是实数集R上的欧氏距离.定义2[1]若序列具有依拓扑收敛到点x的收敛性,则称序列是ρ收敛的,记当且仅当定义3[2]设(X,ρ)是非对称度量空间,对于序列{xn}⊂X,如果存在a∈X使得并且,若b∈X,,则有ρ(a,b)=0,称序列是上收敛的,a是序列{xn} 的上极限,记作同理,如果存在a∈X使得,并且,若b∈X,,则有ρ(b,a)=0,称序列是下收敛的,a是序列的下极限,记作定义4[1]设(X,ρ)是非对称度量空间,对任意的x∈X,r>0,定义X上的开球和闭球如下:Bρ(x,r)={y∈X:ρ(x,y)<r} 开球,Bρ[x ,r]={y∈X:ρ(x,y)≤r} 闭球.注1 非对称度量空间(X,ρ)的拓扑τρ是指由非对称度量ρ诱导的拓扑,即对任意点x∈X的邻域族vρ(x):V∈vρ(x) ⇔存在r>0,使得Bρ(x,r)⊂V⇔存在r′>0,使得Bρ[x,r′⊂V] .由于一个空间有两个拓扑τρ和τ,所以非对称度量空间可以被看作为一个双拓扑空间[1].定理1[2]非对称度量空间(X,ρ)具有如下的拓扑性质:(1)非对称度量空间是T0空间,但不一定是T1空间.(2)非对称度量空间是A1(满足第一可数性公理)空间.(3)由于非对称度量空间未必是T2(Hausdorff)空间,所以其极限一般不具有唯一性.(4)因为非对称度量空间是T0、A1空间,所以非对称度量空间中,列紧、可数紧和序列紧之间是等价的.定义5 若集合X上的二元关系≤满足:(1)(自反性)∀x∈X,有x≤x;(2)(反对称性)∀x,y∈X,x≤y且y≤x,有x=y;(3)(传递性)∀x,y,z∈X,x≤y且y≤z,有x≤z.则称≤是X上的偏序.定义6 设(X,ρ)是非对称度量空间,在其上定义序关系为x≤ρy⇔ρ(x,y)=0.容易证明,≤ρ确实是X上的偏序关系.因此,每一个非对称度量都对应一个偏序关系,反之也成立.例2[4]设(X,≤)是一个偏序集,对于任意的x,y∈X,显然,ρ是一个非对称度量.由ρ诱导的拓扑τ(ρ)称为Alexandroff拓扑.例3[4] R+上的非对称度量ρ:R+×R+定义为:ρ诱导R上的T1拓扑τ(ρ)的基是由所有以x∈R为中心的开球Bρ(x,r)组成,其中0<r<1.拓扑空间(R,τ(ρ))称为Sorgenfrey线.定义7[2]设(X,ρ)是非对称度量空间,是非对称度量空间(X,ρ)中的序列.若对任意的ε>0,存在nε∈N,使得对任意的n,m∈N,且nε≤n<m,有ρ(xn,xm)<ε,则称{xn}是非对称度量空间(X,ρ)中的上柯西序列(在文献[1]中也称为左柯西序列).若对任意的ε>0,存在nε∈N,使得对任意的n,m∈N,且nε≤n<m,有ρ(xm,xn)<ε,则称{xn}是非对称度量空间(X,ρ)中的下柯西序列(在文献[1]中也称为右柯西序列).注2 依ρ收敛的序列不需要是左柯西序列,非对称度量空间比度量空间中的情形更为复杂.定义8[2]设A是非对称度量空间(X,ρ)的子集,如果A中任意上收敛序列的上极限属于A,称A是上闭集.定义9[2]如果非对称度量空间(X,ρ)中的每一个上(下)柯西序列都存在上(下)极限,则称(X,ρ)是上(下)完备的.定义10[1]如果非对称度量空间(X,ρ)中的每一个左(右)柯西序列都是依ρ收敛的,则称(X,ρ)是左(右)完备的.注3 在非对称度量空间(X,ρ)中,左ρ柯西序列与右柯西序列是等价的,而左ρ完备性与右完备性并不等价.因为右完备性是指每一个左ρ柯西序列在(X,)中都是收敛的,而左ρ完备性是指每一个左ρ柯西序列在(X,ρ)中都是收敛的.定义 11[3]设 (X,d)是非对称伪度量空间,对x,y∈X,定义包含 x,y的 X的子集称x,yd是(X,d)的非对称伪度量区间.例4[3]考虑包含4个点的集合X={1,2,3,4},非对称度量q由如下矩阵定义:即qi,j=q(i,j),i,j∈X,可以验证q是X上的非对称伪度量.定义12[3]设(X,d)是非对称伪度量空间.(1)若集合 X中有限序列{x1,x2,…,xn},对任意i<j<k≤n,都有d(xi,xk)=d(xi,xj)+d(xj,xk),则称{x1,x2,…,xn}在(X,d)中是共线性的.(2)若存在一个元素y∈X,使得d(y,x)>0,且对于任意的z∈X,满足(y,x,z)在(X,d)中共线性,都有x=z,称元素x∈X是(X,d)的终点.(3)若存在一个元素y∈X,使得d(x,y)>0,且对于任意的z∈X,满足(z,x,y)在(X,d)中共线性,都有x=z,称元素x∈X是(X,d)的始点.定义13[3]设(X,d)是非对称伪度量空间,若(X,τ(ds))是序列紧致空间,则称(X,d)是间接序列紧致空间.引理1(Zorn′s引理)设P是一个偏序集,若偏序集P中任意的链(即全序子集)在P中都有上界,则偏序集P至少有一个最大元.设(X,ρ)是非对称度量空间,对于x,y∈X,定义连接 x和 y的ρ度量片段为[x;y]ρ={z∈X:ρ(z,x)+ρ(z,y)=ρ(x,y)}.定义14[1]若存在α,0<α<1,使得对每一个x∈X,f(x)≠x,存在z∈[x;f(x)]ρ,z≠x,使得ρ(f(x),f(z))≤αρ(z,x),则称映射f:X→X是一个有向压缩映射.定理2 设(X,ρ)是右完备的非对称度量空间,f:X→X是一个映射使得(i)对于每一个由不同的点组成的序列(ii)对于某一个α,0<α<1,f是一个α有向压缩映射,且对任意的x,y∈X,ρ(f(x),y)≤αρ(x,f(y)).则 f有一个不动点.证明定义函数g:X→R如下:设 {xn}⊂X是由不同的点组成的序列,且则由(i)知,因此,对任意n∈N,有对上述不等式两边同时取下极限得,即函数g在点x处是接近下半连续的.对某一个0<ε<1-α1,存在z0∈X,使得对任意x∈X\{z0},下面证明z0是 f的不动点.若f(z0)≠z0,则由(ii)知,存在z1∈[z0;f(z0)]ρ,z1≠z0,使得又令式(1)中的x=z1,得所以ρ(z0,f(z0))=0.又由f(z0)≠z0,知存在0<α2<1,z2∈[f(z0);z0]ρ,z2≠z0,使得因此,所以,于是,又(X,ρ)是非对称度量空间,知 f(z0)=z0,即z0是 f的不动点.注4 定理2在文献[1]的基础上通过增加说明ρ(f(z0),z0)=0,将文献[1]中的结论由T1非对称度量空间推广到一般的非对称度量空间上.定义15[5]设 f和g是非空集合X上的自映射.如果存在点x∈X,使得w=fx=gx,则称点x是 f和g的一致点,w是 f和g一致点.定义16[5]设 f和g是非空集合X上的自映射,如果 f和g在它们的一致点是可替换的,则称它们是弱一致映射.引理2[5]设 f和g是非空集合X上的弱一致自映射,如果 f和g有唯一的一致点w=fx=gx,则w是 f和g的唯一的公共不动点.定义17[6]设Γ0是所有连续函数F(t1,t2,…,t6):R6+→R的全体,且函数F满足下列条件:(A1) F关于变量t5是非单调增的,(A2)存在某一个函数h1使得对所有的u,v≥0,F(u,v,v,u,u+v,0)≤0,有u≤h1(v),(A3)存在某一个函数h2使得对所有的t,s>0,F(t,t,0,0,t,s)≤0,有t≤h2(s).用Ψ表示函数ψ:[0,∞)→[0,∞)的全体,且函数ψ满足下列条件:(ψ1):ψ是非单调增的,(ψ2):对每一个其中ψn是ψ的n次迭代.注5 容易看出,如果ψ∈Ψ,则ψ(t)<t对任意的t>0都成立.定义18 设Γ是所有连续函数F(t1,t2,…,t6):R6+→R的全体,且函数F满足下列条件:(F0)F(t1,t2,…,t6)=0当且仅当t1=t2=…=t6=0,(F1) F关于变量t5是非单调增的,(F2)存在某一个函数h1∈Ψ使得对所有的u,v≥0,F(u,v,v,u,u+v,0)≤0,有u≤h1(v),(F3)存在某一个函数h2∈Ψ使得对所有的t,s>0,F(t,t,0,0,t,s)≤0,有t≤h2(s).这里h1和h2的假设与定义17中不同,下面关于上述定义给出两个具体例子[8].例5 F(t1,t2,…,t6)=t1-at2-bt3-ct4-dt5-et6,其中a+b+c+2d+e<1,a,b,c,d,e≥0.(F1)显然成立.设u,v≥0,F(u,v,v,u,u+v,0)=u-av-bv-cu-d(u+v)≤0,则即存在函数使得u≤h1(v),(F2)成立.设t,s>0,F(t,t,0,0,t,s)=t-at-dt-es≤0,则有,即存在函数使得t≤h2(s),(F3)成立.例6 F(t1,t2,…,t6)=t1-kmax{t2,t3,…,t6},其中(F1)显然成立.设u,v≥0,F(u,v,v,u,u+v,0)=u-kmax{u,v,u+v}≤0,则有即存在函数使得u≤h1(v),(F2)成立.设t,s>0,F(t,t,0,0,t,s)=t-kmax{t,s}≤0.如果t>s,则t(1-k)≤0,矛盾.因此t≤s,于是t≤ks,即存在函数h2(s)=ks使得t≤h2(s),(F3)成立.定理3 设(X,ρ)是非对称度量空间,函数f,g:(X,ρ)→(X,ρ)使得其中F∈Γ.(fx表示 f(x),gx表示g(x),其他的以此类推).如果 f(X)⊆g(X),g(X)是(X,ρ)的完备的非对称度量子空间且F(t1,t2,…,t6)关于第一个变量非递减,那么函数 f和g存在唯一的一致点.特别地,如果函数 f和g还是弱一致映射,那么 f 和g存在唯一的公共不动点.证明设x0是集合X中的任意一个点,由 f(X)⊆g(X),可以选出点x1∈X使得fx0=gx1.类似地,可以选出x2,x3,…,xn,…,使得 fxn=gxn+1.由(2)式,有于是,由定义18中的性质(F1)和非对称度量的三角不等式知,由定义18中的性质(F2)可以得到如上述重复进行下去,可以得到因此,对于任意的m>n,由非对称度量的三角不等式,可以得到当n,m→∞时,有ρ(gxn,gxm)→0,即{gxn}是左柯西序列.类似地,由(2)式,有于是,由定义18中的性质(F1)和非对称度量的三角不等式知,由定义18中的性质(F2)有如上重复下去有因此,对于任意的n>m与非对称度量的三角不等式有当n,m→∞时,ρ(gxn,gxm)→0,即{gxn}是右柯西序列.因此,{gxn}是柯西序列.由于g(X)是(X,ρ)完备的非对称度量子空间,所以存在点q∈g(X)使得gxn→q=gp,n→∞.下面证明 fp=gp.由(2)式,令x=xn-1,y=p,有即当n→∞时,有由定义18中的性质(F2)知,ρ(gp,fp)=0.同理,由(2)式,令x=p,y=xn-1,有即当n→∞时,有由ρ(gp,fp)=0和(3)式知由F(t1,t2,…,t6)关于第一个变量非递减和(4)式可得因此,F(ρ(fp,gp),0,0,0,0,0)=0.由定义17中性质(F0)知,ρ(fp,gp)=0.故ρ(gp,fp)=ρ(fp,gp)=0,由非对称度量空间的定义知,fp=gp.因此w=fp=gp是函数 f和g唯一的一致点.此外,如果函数 f和g还是弱一致映射,由引理2可知,w是 f和g的唯一的公共不动点.注6 定理3是在本文定义的非对称度量空间下(不同于文献[7]中的非对称度量空间)研究映射的公共不动点问题,它是文献[7]中定理2的推广.推论1 设(X,ρ)是非对称度量空间,函数f,g:(X,ρ)→(X,ρ)使得对任意的x,y∈X,成立,其中如果 f(X)⊆g(X),g(X)是(X,ρ)的完备的非对称度量子空间,那么函数 f 和g存在唯一的一致点.特别地,如果函数 f和g还是弱一致映射,那么 f和g存在唯一的公共不动点.证明取F是例6中的F,即F(t1,t2,…,t6)=t1-kmax{t2,t3,…,t6},其中显然,F(t1,t2,…,t6)关于第一个变量是非递减的,由定理3知结论成立.[1]CHEN S B,TIAN S P,MAO

偏好凸向原点的英文

偏好凸向原点的英文

偏好凸向原点的英文## Convex Preferences and the Origin.In economics, a preference relation is a binaryrelation that represents an individual's preferences over a set of alternatives. A preference relation is said to be convex if it satisfies the following condition:> For any three alternatives x, y, and z, if x is preferred to y and y is preferred to z, then x is preferred to any convex combination of y and z.In other words, a preference relation is convex if, for any two alternatives x and y, the individual prefers any weighted average of x and y to any alternative that is not on the line segment connecting x and y.Convex preferences have a number of important implications. First, they imply that the indifference curves of an individual are convex. An indifference curveis a curve that represents all of the alternatives that an individual is indifferent between. If an individual's preferences are convex, then their indifference curves will be bowed outward, as in the following diagram:[Image of a convex indifference curve]Second, convex preferences imply that the demand curve of an individual is downward sloping. A demand curve is a curve that shows the relationship between the price of a good and the quantity of the good that an individual demands. If an individual's preferences are convex, then their demand curve will be downward sloping, as in the following diagram:[Image of a downward sloping demand curve]Third, convex preferences imply that the utility function of an individual is quasi-concave. A utility function is a function that represents an individual's preferences over a set of alternatives. If an individual's preferences are convex, then their utility function will bequasi-concave, which means that the level sets of theutility function will be convex.Convex preferences are a common assumption in economic models. This is because convex preferences are consistent with a number of reasonable assumptions about human behavior. For example, convex preferences are consistent with the assumption that individuals are risk-averse.## Applications of Convex Preferences.Convex preferences have a number of applications in economics. For example, convex preferences can be used to explain why individuals demand more of a good when its price decreases. This is because, when the price of a good decreases, the individual can afford to purchase more of the good without giving up any other goods.Convex preferences can also be used to explain why individuals are willing to pay more for a good when its quality increases. This is because, when the quality of a good increases, the individual's utility from consuming thegood increases.Finally, convex preferences can be used to explain why individuals are more likely to choose a risky option when the expected value of the option is high. This is because, when the expected value of a risky option is high, the individual's expected utility from choosing the option is also high.## Conclusion.Convex preferences are a powerful tool for understanding human behavior. Convex preferences can be used to explain a wide range of economic phenomena, including the shape of indifference curves, the slope of demand curves, and the behavior of individuals under uncertainty.。

CFA一级笔记-第八部分 固定收益证券

CFA一级笔记-第八部分 固定收益证券

CFA一级考试知识点第八部分固定收益证券债券五类主要发行人超国家组织supranational organizations,收回贷款和成员国股金还款主权(国家)政府sovereign/national governments,税收、印钞还款非主权(地方)政府non-sovereign/local governments(美国各州),地方税收、融资、收费。

准政府机构quasi-governments entities(房利美、房地美)公司(金融机构、非金融机构)经营现金流还款Maturity到期时间、tenor剩余到期时间小于一年是货币市场证券、大于一年是资本市场证券、没有明确到期时间是永续债券。

计算票息需要考虑付息频率,未明确的默认半年一次付息。

双币种债券dual-currency bonds支付票息时用A货币,支付本金时用B货币。

外汇期权债券currency option bongds给予投资人选择权,可以选择本金或利息币种。

本金偿还形式子弹型债券bullet bond,本金在最后支付。

也称为plain vanilla bond(香草计划债券)摊销性债券amortizing bond,分为完全摊销和部分摊销。

偿债基金条款sinking found provision,也是提前收回本金的方式,债券发行方在存续期间定期提前偿还部分本金,例如每年偿还本金初始发行额的6%。

票息支付形式固定票息债券fixed-rate coupon bonds,零息债券会折价发行,面值与发行价之差就是利息,零息债券也称为纯贴现债券pure discount bond。

梯升债券step – up coupon bonds票息上升递延债券deferred coupon bonds/split coupon bonds,期初几年不支付,后期才开始支付票息。

(前期资金紧张或研发型项目)实物支持债券payment-in-kind/PIK coupon bonds票息不是现金,而是实物。

统计学专业名词(中英对照)

统计学专业名词(中英对照)

统计学专业名词·中英对照我大学毕业已经多年,这些年来,越发感到外刊的重要性。

读懂外刊要有不错的英语功底,同时,还需要掌握一定的专业词汇。

掌握足够的专业词汇,在国内外期刊的阅读和写作中会游刃有余。

在此小结,按首字母顺序排列。

这些词汇的来源,一是专业书籍,二是网上查找,再一个是比较重要的期刊。

当然,这些仅是常用专业词汇的一部分,并且由于个人精力、文献查阅的限制,难免有不足和错误之处,希望读者批评指出。

计量经济学(重要名词解释)

计量经济学(重要名词解释)

——名词解释将因变量与一组解释变量和未观测到的扰动联系起来的方程,方程中未知的总体参数决定了各解释变量在其他条件不变下的效应。

与经济分析不同,在进行计量经济分析之前,要明确变量之间的函数形式。

经验分析(Empirical Analysis):在规范的计量分析中,用数据检验理论、估计关系式或评价政策有效性的研究。

确定遗漏变量、测量误差、联立性或其他某种模型误设所导致的可能偏误的过程线性概率模型(LPM)(Linear Probability Model, LPM):响应概率对参数为线性的二值响应模型。

没有一个模型可以通过对参数施加限制条件而被表示成另一个模型的特例的两个(或更多)模型。

有限分布滞后(FDL)模型(Finite Distributed Lag (FDL) Model):允许一个或多个解释变量对因变量有滞后效应的动态模型。

布罗施-戈弗雷检验(Breusch-Godfrey Test):渐近正确的AR(p)序列相关检验,以AR(1)最为流行;该检验考虑到滞后因变量和其他不是严格外生的回归元。

布罗施-帕甘检验(Breusch-Pagan Test)/(BP Test):将OLS 残差的平方对模型中的解释变量做回归的异方差性检验。

若一个模型正确,则另一个非嵌套模型得到的拟合值在该模型是不显著的。

因此,这是相对于非嵌套对立假设而对一个模型的检验。

在模型中包含对立模型的拟合值,并使用对拟合值的t 检验来实现。

回归误差设定检验(RESET)(Regression Specification Error Test, RESET):在多元回归模型中,检验函数形式的一般性方法。

它是对原OLS 估计拟合值的平方、三次方以及可能更高次幂的联合显著性的F 检验。

怀特检验(White Test):异方差的一种检验方法,涉及到做OLS 残差的平方对OLS 拟合值和拟合值的平方的回归。

这种检验方法的最一般的形式是,将OLS 残差的平方对解释变量、解释变量的平方和解释变量之间所有非多余的交互项进行回归。

基于 Barrodale 和 Roberts (1973,以下简写为 BR)提出的单纯形法 (simplex algorithm),Koenker 和 D’Orey(1987)提出一种估计分位数回归 系数的方法。EViews 中应用的是 BR 算法的改进形式。

式(1)求极小的一阶条件是 E( yt ) = 0,即 2F() -1 =0, F() 0.5 。这意味着等于中位数
对于不同分位数回归函数如果回归系数的差异很大,说明在不同分位 数上解释变量对被解释变量的影响是不同的。

1 Introduction
This paper deals with weighted quasi-arithmetic means of an interval. Weighted quasi-arithmetic means are important tools in subjective estimation of data in decision making such as management, artificial intelligence and so on ([3–5]), and it is also strongly related to utility and stochastic risk in economics ([6]). Kolmogorov [9] and Nagumo [10] studied the aggregation operators and Acz´el [1] developed the theory regarding weighted aggregation. Yoshida [12–15] has studied weighted quasi-arithmetic means of an interval by utility functions and weighting functions from viewpoint of subjective decision making. In relation to decision making, a weighted quasi-arithmetic mean is defined as follows. For a continuous strictly increasing function f : [a, b] → (−∞, ∞) as decision maker’s utility function and for a continuous function w : [a, b] → (0, ∞) as weighting function, a weighted quasi-arithmetic mean on a closed interval [a, b] is given by

Abstract. This paper discusses weighted quasi-arithmetic means from viewpoint of a combined index of utility functions and weighting functions, which represent stochastic risk in economics. The combined index characterizes decision maker’s attitude and background risks in stochastic environments by conditional expectation representations of weighted quasi-arithmetic means. The first-order stochastic dominance and risk premium are demonstrated using weighted quasi-arithmetic means and aggregated mean ratios, and they are characterized by the combined index. Finally, examples of weighted quasi-arithmetic mean and aggregated mean ratio for various typical utility functions are given.
In Section 2, we give the definitions of weighted quasi-arithmetic means and aggregated mean ratios of weighted quasi-arithmetic means by interior ratios, and we show the relation among weighted quasi-arithmetic mean, aggregated mean ratio and decision maker’s preference/attitude based on his utility and weighting. In economics, decision maker’s attitudes, for example risk neutral, risk averse and risk loving, are characterized by Arrow-Pratt index of utility functions([2, 11, 7, 8]), and risks in stochastic environments are given as an index of weighing functions. In Section 3, this paper characterizes weighted quasiarithmetic means and mean ratios by not only utility functions but also weighing functions as a combined index. Next we investigate properties of weighted quasiarithmetic means and aggregated mean ratios regarding combinations of utility functions and weighting functions. Representing weighted quasi-arithmetic means by conditional expectations, we investigate relation between the index for stochastic risks and risk premium in economics. We also discuss the firstorder stochastic dominance using weighted quasi-arithmetic means. Finally, in Section 4, we show a lot of examples of the weighted quasi-arithmetic means and the aggregated mean ratios with various typical utility functions, and we demonstrate their relations with the classical quasi-arithmetic means.
