$$
(1+r) c^{\prime}\left(T^{-}\right)=s \alpha \beta<(1-s) \alpha+s \beta \alpha
$$
The left-hand is the marginal cost of training. The right-hand side is the marginal gain from training, which is realized only if the pair remain together. So $\overrightarrow{T^{h}}<\hat{r}$. The gain to the pair from choosing to adopt the technology and train the worker is
$$
(1-s) a T^{-h}-(1+r)\left(\bar{\delta}+c\left(\bar{T}^{h}\right)\right)
$$

ECON20022T/ECON20512T COURSE NOTES ：

Using a circumflex over a variable to represent percentage change in it, we can now get
$$
\hat{D}=a \hat{p}+b
$$
where $a=M \eta-N(1-\eta)$, with $M=I_{z} / D, N=I_{1}, x_{w} / D, M \geq N$, and $\eta$ is the (positively defined) price elasticity of demand for import in the poor country (with an overbar for the rich country); and
$$
b=M e_{c} \hat{y}-N \bar{e}_{m} \bar{y}+M \hat{L}-N \bar{L}
$$
with $\ell$ as the income elasticity of demand for the good denoted by the subscript.
