AR模型不就违反了模型错误中的 Including lagged dependent variables as independent variables in regressions with serially correlated errors. 将滞后变量作为自变量 这一条嘛
已回答R25课后题第一题D计算已实现的超额收益。超额收益是用内在价值IV减去市场价格MP。但每次涉及用required return 和realized return算超额收益时就搞不清谁减谁。是要先区分哪个收益率用来算内在价值,哪个收益率用来算市场价格吗? 那么算内在价值是用required return来折现的吧,那么为何不用required return- realized return呢?

- Q3:解析里面Team Purple’s conclusion (the externalities associated with human capital is the most important determinant in predicting the occurence of convergence) implies that the production function is a straight line, and is compatible with non-convergence.这段话中 externalities associated with human capital具体是什么?怎么得到the production function is a straight line这个结论呢?
- Growth due to capital deepening 是αΔK/K还是ΔK/K
- 这题为什么是选C?
- 请老师讲解一下这个题目
- 老师,第二题可以在解释一下原理吗?
- 老师,第三题答案的意思是:1.因为宽松的货币政策,导致加元利率下跌,导致加元贬值?2.但是,如果利率下跌,也就是分母上的百分比下降,不是会导致价格上升吗?。3.从而短期看是depreciation,但是长期来看,会回归到均值,所以是appreciation?
- CDS的long和short是不是反过来的?就是long CDS代表看涨目标公司credit,所以是卖出一份CDS合约?
- 很迷惑到底是long call+ short stock还是long stock+short call构建无风险资产
