2018-11-10 22:06解釋里說As spreads widened, the exogenous spread approach would reflect this in higher liquidity adjusted VaR, but the constant-spread approach would not. constant-spread approach不也是spread增加,LVaR增加么。另一句說In the endogenous price approach, a higher value for the price elasticity of demand would result in higher VaR. Elasticity增加不應(yīng)該LVaR減少么

同學(xué)你好,constant spread approach假設(shè)spread是一個恒定的值,如果spread在變的話,那么它影響的是random spread approach的計算
彈性E=(ΔP?P)/(ΔN?N),彈性本身是一個負值,如果彈性增加的話,根據(jù)公式"LVaR"=VaR×(1-ΔP/P)=VaR×(1-E×ΔN/N),LaR應(yīng)該增加才對
