老师 请问 答案中more less表示什么意思呢

解释里说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。另一句说In the endogenous price approach, a higher value for the price elasticity of demand would result in higher VaR. Elasticity增加不应该LVaR减少么
