The long run aggregate supply curve (LRAS) is determined by all factors of production – size of the workforce, size of capital stock, levels of education and labour productivity. If there was an increase in investment or growth in the size of the labour force this would shift the LRAS curve to the right.

What makes the LRAS shift left?

Other Supply Shocks An extreme example might be an overseas war that required a large number of workers to cease their ordinary production in order to go fight for their country. In this case, SRAS and LRAS would both shift to the left because there would be fewer workers available to produce goods at any given price.

What are shifters of long run growth?

The position of the long-run aggregate supply curve is determined by the aggregate production function and the demand and supply curves for labor. … Other developments that could produce an upward shift in the curve include an increase in the capital stock or in the availability of natural resources.
