If h$$rises $($the total hours available$)$ in the economy, summarize the direct effects on labor supply and labor demand, the direction of the indirect effect, the effect on key equilibrium variables, and state whether the resulting equilibrium is efficient.

I was wondering whether the PPF has a parallel shift outward or proportionately when h rises? Since h$$is an exogenous variable in the consumer's decision problem, I understand that it directly affects the labor supply curve. However, I$$m unsure about how this change would visually look on the one$-$period equilibrium model.
