Capital and labour markets - COFFEE-TEA
The macroeconomic closure assumes full employment of the factors of production (capital and labour). Savings equals investment in the general equilibrium, but regionally the imbalances are closed by a surplus (or deficit) in the current account. An endogenous real exchange rate clears the current accounts and the capital account decreases exougenously in the long-run. Capital stock evolves at each period with the formation of new capital that depends on the investment level in that period and the capital depreciation rate, as described in Equation 2
where:
$K{_{r,t}}$ is the capital stock in region $r$ and time $t$;
$I{_{r,t}}$ is the investment in new capital goods in region $r$ and time $t$; and
$\delta{_r}$ is the depreciation rate of capital in region $r$.
