1. Suppose the labour force in an economy is 100, its long run employment rate is 95% and its labour productivity (GDP/E) is 100. If current GDP is 850, the economy is in long and short run equilibrium.

2. If an aggregate production function exhibits diminishing marginal product and constant returns to scale then an increase in the labour force leads to a decrease in output per worker.
