    Can the full employment GDP increase over time, when there are increase in technology-leading to higher productivity in the economy, increase in supply of labour and capital, increase in efficiency?

      Yes, full-employment GDP is the potential GDP = Total Hours Worked x Labor productivity. I believe it's called sustainable growth when the potential GDP grows over time, which can be driven by either increase in labor force, or increase in labor productivity. Labor productivity (Y/L) can be further determined by Capital-to-labor ratio(K/L) and technology advancement (A) given we assume aggregate production function as Y=A*f(L,K) and the function is hom*ogeneous to degree one. But solely increase in the input of capital won't help sustain growth, especially when capital per worker is already very high in most developed countries, because of the diminishing return. To answer your question, I believe tech advance and increase in labor supply will certainly drive full employment GDP, as for increase in capital, it depends. Hope it helps.

    1.) The economic reason that the aggregate supply curve slopes us is because when the price level for outputs increases while the price level of inputs remains fixed, the opportunity for additional profits encourages more production.
    2.) The components of the aggregate demand curve are: Consumption, Investment, Government Spending, and Net Exports.
    3.) The economic reasons that the aggregate demand curve slopes down because it shows the relationship between the price level for outputs and the quantity of total spending in the economy.
    4.) The near-horizontal shape of the aggregate supply curve on its far left represents real GDP—that is, the level of GDP adjusted for inflation.
    5.) The near-vertical shape of the aggregate supply curve on its far right represents the price level which is an index number, like the GDP deflator.
    6.) Potential GDP is the maximum quantity that an economy can produce given full employment of its existing levels of labor, physical capital, technology, and institutions.

    "The interest rate effect explains that as outputs rise, the same purchases will take more money or credit to accomplish. " How does this follow? If outputs rise, shouldn't prices fall?

      As the outputs rise the price levels will also rise(refer to short-term supply curve ).So far the interest rate is concerned the central banks would impose more interest rate for lending the money as there will be more demand for money now (since price level have gone up and more money is required for making a purchase at the current price levels)
      So as the interest levels rise, businesses and households will be unwilling to take loans at such an increased interest rate which affects the Investment (I) and also the Consumption(C) components of the aggregate demand.

      The answer belongs to this paragraph

      "The economic intuition here is that if prices for outputs were high enough, producers would make fanatical efforts to produce: all workers would be on double-overtime, all machines would run 24 hours a day, seven days a week. Such hyper-intense production would go beyond using potential labour and physical capital resources fully to using them in a way that is not sustainable in the long term. Thus, it is indeed possible for production to sprint above potential GDP, but only in the short run."

      That means, the production just condusively taking a long-run if they are stay in the potential GDP and taking rest the energy to another they. If the company pursue the production into long-run AS or the real AS possibility, they just can take it a short-run because the labour factor can't stay handle it in long-run.

      The long-run aggregate supply curve is more leftward than the potential GDP/Full-employment GDP line because the LRAS curve represents the standard production level of a healthy economy, No it doesn't.

    1. What is the economic reason that the aggregate supply curve, or short run aggregate supply curve, slopes up?
    ~ The aggregate supply curve slopes up because when the price level for outputs increases while the price level of inputs remains fixed, the opportunity for additional profits encourages more production.

    2. What are the components of the aggregate demand curve?
    ~ Aggregate demand includes all four components of demand: Consumption
    Investment; Government spending; Net exports—exports minus imports

    3. What are the economic reasons that the aggregate demand curve slopes down?
    ~ This downward slope indicates that increases in the price level of outputs lead to a lower quantity of total spending.

    4. Briefly explain the reason for the near-horizontal shape of the aggregate supply curve, or short run aggregate supply curve, on its far left.
    ~ The far left of the aggregate supply graph is nearly flat because its listing when the economy is far below its potential GDP (maximum quantity that an economy can produce.

    5. Briefly explain the reason for the near-vertical shape of the aggregate supply curve, or short run aggregate supply curve, on its far right.
    ~ This happens when unemployment is practically zero, and all factories are running at full capacity.

    6. What is potential GDP?
    ~ Potential GDP is the maximum quantity of an economy can produce given full employment of its existing levels of labor, physical capital, technology, and institutions.
