Currently the Obama administration is talking about finding new ways to create jobs and stimulate growth. However, it has proved to be unsuccessful, as the only policy that will really help is an increase in aggregate demand. The article explains that aggregate demand simply means spending: "spending by households, businesses and governments for consumption goods and services or investments in structures, machinery and equipment." At the moment, businesses should not to invest because there is lack of consumer demand. The federal government could increase aggregate spending by directly employing workers or undertaking public works projects yet this proves to be difficult. The author explains that the most important thing is for policy makers to stop focusing on debt and attempt instead to raise aggregate demand.

THis article talks about how the recession has effected America and what America really needs is an increase in aggregate demand. That is the increase in consumption, investments, exports etc. They say that a direct solution to increase aggregate demand would be an increase in aggregate spending by employing citizens in public projects controlled by the government and if that isnt enough then its all up to the citizens. It then talks about how consumer confidence significantly effects spending. that is if house holds feel that they are rich, then they dont feel the need to save and as a result of that they spend the money they were going to spend and vice versa.

If aggregate demand were to expand, would there be sufficient spare capacity to allow aggregate supply to expand to meet the additional demand? This is the question addressed by the podcast and article below.

This article talks about how the unemployment is affecting the United States and how it is related to a decrease in the aggregate demand of the country. And how this possibly causes the real GDP being 6 percent under the trend path.

This article tells us how the recession in the United States has affected the unemployment rate; people consume less thus the aggregate demand is lower and remains like this as unemployment increases. I also found important something that is mentioned: "During a deep recession, more workers move into the category of those who take a long time to find new jobs, and so the decline in unemployment across the labour force as a whole is quite slow" Factors mentioned in this article are what determine the real GDP to be 6% under the trend path.

This article talk about how technology is improving at a rapid pace and thus leading to unemployment in the manufacturing sector. Since these manufacturing industries comprise three quarters of the 20- sub industry sectors, the level of unemployment is considered quite large. Some of these sub industries are leather tanning, paper mills, fertilizer factories, glass products etc. Another influencing factor in the drop of aggregate demand in the U.S is the shift in the age of the labor force. According to statistics, by 2020, people over 55 will compose of more than 25% of the labor force in manufacturing.

This article shows how the environment can influence the aggregate supply in the economy. The article states that heat stress from global warming may be having an impact on outdoor work productivity in hot regions like northern Australia, Southeast Asia and the southern US. And the calculation tells us thatin temperate regions, people work continuously, but in the hottest places, the working day is split between 80% work and 20% rest. Therefore, people and government should pay attention to the environment problems nowadays because it will lead to a change in nation's GDP. And economists also should consider environment as a determinant of aggregate supply.

This article talks about how global warming is causing a decrease in work productivity, which would lead to a decrease in production. It states that in the hottest months of the year, labour capacity decreases by around 10%. They estimate that by 2050 the temperature would have risen by 1.8 degrees. At this temperature labour capacity would decrease by 20%. So overall this could have huge effects on the economy as production will decrease, and therefore there will be over aggregate demand. this then would cause inflation.

Singapore's labour productivity- defined as average output per period of time- fell by 2.6 percent in 2012. This includes the manufacture sector, construction sector, and service sector. Only the information and communicators sector show a positive increase. Labour productivity has been decreasing continuously. In the fourth quater of last year, labour productivity fell by 2.5 percent, which is the fifth consecutive quater showing a decline. The numbers attribute to the slower economic growth in the past two years. The government has been trying to increase productivity in certain sectors that see the most potential increase. Not only that, nominal wages- wages not yet adjusted for inflation- shows a 2.3 percent increase. Unemployment rate is 2%. The article can be related to aggregate supply. If labour productivity sees a decrease, it is likely that aggregate supply falls as well since labour is one of the factor of production. If the country sees a fall in its output then this suggests a decrease in the growth of the economy or may even reflect in the country's GDP value. Not only that, an increase in wages will also increase firms' cost of production, and therefore contribute to a fall in aggregate supply. However, on a good note, its unemployment rate is at 2%, which is considered as quite a good rate. This may suggest a quite full working capacity of the economy.

This article talk about the price of a gallon of 95 octane will increase 22 cents to $4.54. The price of 91 octane will increase 20 cents to $4.16. Diesel prices will go up 15 cents to $4.08. I´ve found this article and I think that is related to our actual topic aggregate supply because an increase in the price of the natural gas will have an impact on all industries, as oil is widely used in a lot of production processes. This will lead to a shift of the aggregate supply curve because the factors of production will be more expensive and at higher level price the producer will reduce the total amount of goods and services

The article does not talk about the whole aggregate demand, but rather focus on one component that contributes to aggregate demand. The article talks mainly about exports in Spain, contributing to its nation's economic growth. Spain's exports figures have increased despite the recession phase. The exports have broke a record of the least trade deficit since 1998. Exports increase to 222.6 billion euros in 2012 from 215.2 billion euros in 2011, which is the highest exports since 1971. Spain's trade deficit decreased 34% as imports fell 2.8%. This is due to changes in exchange rate and improvements in competitiveness. Apart from that, measures like labor law changes have improved investors' confidence.

The cement company Lafarge, says that UK faces a 200 million tonnes shortfall due to slow planning procedures. There is an extremely high demand currently in the UK. If this continues or increases, then the countries capacity to supply will begin to decline after 10 years. Out of the 200 million tonnes, only 60 is recyclable which leaves the rest to be extracted from primary sources. Since the procedure to quarry materials from primary sources requires authority permission, the process is very slow. This slow process is going to create the shortfall says Lafarge.

This article talks about the possibility of deflation in the US. Deflation would be a problem for a number of reasons: first, deflation would make it more difficult to engineer an economic recovery; second, deflation could result in a "death spiral" like what happened (according to one interpretation) during the early 1930s. This article suggests that unlike times of good economic state, the policy that should be taken during a crisis should be decreasing supply instead of increasing it, this would be the easiest way to stop deflation.

This article talks about how the government is trying to Real GDP of the country by lowering the taxes on exporting oil prices. By doing this the governmnet has enevitably increased the Real GDP because siince the oil firms FOP cost less they can now supply more oil, also the price will rise from 42$ per barrel to 70$ per barrel meaning that the oil firms will even make more of a profit. Again since the taxes have decreased it will cause foreign investments in the oil industry of Argentina since they just discovered that Argentina is setting on one of the biggest oil deposits. so overall, the long term aggregate will shift to the right, an increase in the real GDp

Argentina has devised a new system of export taxes on oil shipments that will cut taxes, as the government seeks to encourage investments to revive production. The change means energy companies will receive $70 per barrel of exported oil, up from $42 previously. Argentina controls the price of oil exports in order to guarantee domestic supply. The reform means that the state will only retain the difference between the market prices, meaning increased revenue for oil companies that export crude. The long run aggregate supply is expected to shift the right, an increase in the real GDP.

This article talk about how the Anti-japanese riots in China attack Japanese suppliers. If you take Japanese cars, people in China will be less likely to buy a Japanese car, because due to the riots, they will be assaulted and destroyed. This will lead to a decrease in the aggregate supply of these cars in China, since suppliers know that people will be less likely to buy these cars during the riots.

What this article talks about is the two points of view, which are completely different in nature, to why the US economy is failing. The one point of view is that there is too little aggregate demand and an excesive supply of wasted potencial. The other view is that there is too much government intervention. It talks about how the recession has effected investments and aggregate demand and therefore decreased the average wages of the country. The article states that a solution to the problem would be the fiscal policy where the governmnet would lower percentage taxes in order for the rich to start investing again. This would then promote the recovery of the economy.

The article talks about the overall German economy. The economy ministry states that although there is weak development in industrial output to the point where there is contraction the GDP during the fourth quarter of 2012, there are many signs that indicate the growing economy. He states that the economy has reached its lowest point already. The country sees a growth of 0.8 percent in industrial orders as there is an increase in euro zone. Furthermore, many surveys indicate that many businesses, investors, and consumers are becoming more optimistic. Data has shown that there is increase in exports, international trade, and as well as a decrease in unemployment. Contribute by a narrowed US trade deficit indicates an increase in global demand. This article can be related back to the business cycle. As you can see, by description, German's economy is in a trough phase and with evidences indicating that it is leading towards the recovery phase. This shows that there is a lowest point in the phase where the economy can not get any worse. There is a point that there is still consumption. We can also see that during the recession, GDP decreases, aggregate output decreases, aggregate demand decreases, and unemployment increases. This clearly reflects the business cycle.

Foreign direct investment in Mexico has increased 178 percent in 2013 from the the $12.7 billion seen in 2012. The increase in foreign direct investment was stimulated through economic reforms in industries ranging from telecoms to energy, which was pushed through Congress by President Enrique Pena Niet. The economic reforms has lured in many investors. Increase in foreign direct investment can help stimulate aggregate demand in Mexico, since there are an increase in capital inflows into Mexico. With an increase in aggregate demand, the country GDP can increase, and therefore contribute to economic development. The article also states that the investment was largely made into manufacturing sector. This could help contribute to research and development for machines or technology.

It is an article about the recession and unemployment in Spain. The unemployment is a very serious problem in Spain because the rate of unemployment is about 25% or more so is a lot. This article report that the Spanish situation is stabilizing but we can´t assume that is the end of the recession and the start of the new business cycle. The business cycle is the periodic fluctuations in economic activity measured by changes in real GDP. Output cannot continue to fall for ever as there will always be some people with jobs to maintain a given level of consumption, foreigners will demand exports, governments will continue to spend by running budget deficits, and people will be able to use savings to finance their consumption. Additionally, the low demand for money for investment will result in lower interest rates. Thus, aggregate demand will pick up, the economy will enter the recovery phase, and the cycle will repeat itself. So after the recession the national economy of Spain will suffer an economic growth, the amount of the goods and services produced by an economy over time will increase.

LISBON: The Portuguese economy is set to contract by 2.3 per cent this year due to a sharp fall in domestic demand and disappointing export growth

This article basically talks about the decreasing growth of the Portuguese economy. It states that the Portuguese economy will contract by 2.3% this year due to a steep fall in aggregate demand and exports. This can only lead to negative consequences as the firms will start to sell less/produce less and therefore earn less of a profit or no profit at all. SO what these firms will start to do is cut costs of FOP which basically means lay off workers, raising unemloyment, further worsening the economy, because then the people laid off will buy less from other firms and the same process will occur over and over again untill you get to the economic situation of Greece.

Central Bank of Russia will continue to cut interest rates to 8% at which central bank lends to commercial banks. This target is to be completed in early May. This action is done in the hope to boost Russia's economy after a slow down. In addition, inflation rates are beginning to decline. Lower interest rates will lower costs of saving and thus encourage people to invest or get a loan to consume goods such as houses. This will move aggregate demand outwards and as well ad economy's potential output. This, in turn, will encourage economic growth. As such, this method can be classified as a part of an expansionary monetary policy or reflationary policy.

It is an article about the important of fiscal policies in the emergent economies, where the fiscal policies remain very conservative. The fiscal policy would be very helpful to continue the economic growth and create jobs. The fiscal policy is a very good method to encourage greater consumption or investments, and as when know, when there is an increase in investments or consumption there will be an increase in the aggregate demand. Axa Framlington fund manager Julian use as example the Mexico's economy that is demonstrating a strong economic growth because they use efficiently the fiscal policy.
