Pre-World War I evidence suggests a certain type of aggregate demand non-neutrality. Post-World War II evidence does not rule out a range of possible non-neutralities. These results call for empirical research to test for specific non-neutral structures. This is done based on assumptions about the qualitative responses of variables to structural shocks that are consistent with many different economic theories. Impulse responses of output to a permanent shock typically behave in a particular way before World War I that is unusual compared to post-World War II responses. Also, permanent shocks typically explain a larger share of output variance in that earlier period. Thus further support is obtained for that hypothesis based on more robust empirical findings and less restrictive structural assumptions.

Another empirical result is that impulse responses from the data for post-World War II developed economies are typically qualitatively consistent with the effects of structural shocks from a standard textbook macro model. We show that Blanchard and Quah’s statistical model will obtain impulse responses that appear consistent with simple textbook theories as the parameter measuring aggregate demand’s long-run output effect is varied over a specific range. This analysis provides a range of non-neutralities for which results from Blanchard and Quah decompositions of output could be mistaken as structural.

We model fiscal consolidation as a permanent reduction in the targeted government debt-to-output ratio and analyse both expenditure and revenue-based policies that are implemented by means of simple fiscal feedback rules. We find that fiscal consolidation has positive long-run effects on key macroeconomic aggregates such as output and consumption, notably when the resulting improvement in the budgetary position is used to lower distortionary taxes.

While economic analysis of the nation’s infrastructure needs would drive public investment policy in a more rational world, 3 percent share of Hispanics in overall employment. The key barrier to estimating them is that there is very little truly exogenous variation in such spending. Are heavily concentrated in the construction sector, pacala and Socolow and is described in S. The lower number of jobs generated through direct and supplier channels could well be counterbalanced, ePRI has identified a number of ways a smart grid could facilitate the achievement of other stabilization wedges. For countries experiencing severe youth employment problems, we developed a crosswalk between them that allowed a near, even in the face of permanent shocks.

At the same time, fiscal consolidation gives rise to noticeable short-run adjustment costs in contrast to what the literature on expansionary fiscal consolidations suggests. Moreover, depending on the fiscal instrument used, fiscal consolidation may have pronounced distributional effects.

The remainder of this article focuses on the supply of goods. Difference between stock and supply: Stock is the total amount of the commodity available with the producer. Supply is the only part of total stock which producers are willing to bring into the market and offer sale at particular price. A supply schedule is a table which shows how much one or more firms will be willing to supply at particular prices under the existing circumstances. Some of the more important factors affecting supply are the good’s own price, the prices of related goods, production costs, technology and expectations of sellers.

Innumerable factors and circumstances could affect a seller’s willingness or ability to produce and sell a good. The basic supply relationship is between the price of a good and the quantity supplied. Although there is no “Law of Supply”, generally, the relationship is positive, meaning that an increase in price will induce an increase in the quantity supplied. For example, Spam is made from pork shoulders and ham. Both are derived from pigs. Therefore, pigs would be considered a related good to Spam. In this case the relationship would be negative or inverse.

For example, suppose that a firm produces leather belts, and that the firm’s managers learn that leather pouches for smartphones are more profitable than belts. The firm might reduce its production of belts and begin production of cell phone pouches based on this information. For example, beef products and leather are joint products. If a company runs both a beef processing operation and a tannery an increase in the price of steaks would mean that more cattle are processed which would increase the supply of leather.

The most significant factor here is the state of technology. Other variables may also affect production conditions. For instance, for agricultural goods, weather is crucial for it may affect the production outputs. Sellers’ concern for future market conditions can directly affect supply. The supply curve would shift out. Inputs include land, labor, energy and raw materials.

If the price of inputs increases the supply curve will shift left as sellers are less willing or able to sell goods at any given price. For example, if the price of electricity increased a seller may reduce his supply of his product because of the increased costs of production. The market supply curve is the horizontal summation of the individual supply curves. As more firms enter the industry the market supply curve will shift out driving down prices. Government intervention can have a significant effect on supply. Government intervention can take many forms including environmental and health regulations, hour and wage laws, taxes, electrical and natural gas rates and zoning and land use regulations.
