The paper asserts, that macroeconomics is a field still undergoing constant revolution, citing 2008 financial crisis that led the abandonment of the Great Moderation consensus.
Macroeconomics focuses on the performance of the economy in its entirety. For a very long time, economists belonging to different schools of thought have attacked each other in a bid to prove that their approach is the best for emerging economic problems. However, each macroeconomic thought seems to be redundant when the world continues to encounter new economic problems demanding new thoughts all together
Prior to the Keynesian Revolution, the classical school of thought is the economic thought that dominated economic world. At that time, classical economist had not crafted any theory or model for macroeconomics. Macroeconomic thoughts were basically in the form of hypotheses.
The failure of classical macroeconomic postulates led to the emergence of Keynesian Revolution, which dominated global economic systems until mid 1960s. John Maynard Keynes steered this task in his ‘General Theory’, which formed the basis of macroeconomics.
Keynesian economics also began to exhibit flaws and this led to the development of other school of thoughts as mentioned in the paper.
The paper concludes that old theory and policies become obsolete because new macroeconomic events demand foe new approaches.
Introduction Macroeconomics focuses on the performance of the economy in its entirety. For a very long time, economists belonging to different schools of thought have attacked each other in a bid to prove that their approach is the best for emerging economic problems. However, each macroeconomic thought seems to be redundant when the world continues to encounter new economic problems demanding new thoughts all together. During 1930s, the United States capitalist system practically stopped working. The U.S free-market economy could not function at the desired level for over a decade (1929-1940). The Great Depression not only caused mayhem to the country’s economy, but to the entire world. The failure of classical economics to explain and provide solutions to the effects of the Great Recession of 1930s led to the birth of numerous economic thoughts aimed at providing answers to economic questions emanating from the underlying problems. This paper explores the classical economics and its failures that led to the development of new macroeconomic thoughts following the Great Recession of 1930s. The Classical Macroeconomics and the Great Depression Prior to the Keynesian Revolution, the classical school of thought is the economic thought that dominated economic world. At that time, classical economist had not crafted any theory or model for macroeconomics. Macroeconomic thoughts were basically in the form of hypotheses. Based on classical school of thought, free interaction of the forces of demand and supply will result into the following conditions: First, full employment will be achieved in the long-run (LR) and the problem of unemployment will only be experienced in the short-run (SR), if any. Second, there will be no overproduction or underproduction in the economy at the aggregate level. Third, the economy will ever be in equilibrium in the long-run (Dwivedi 13). However, the Great Depression of 1930s disapproved the claims of all the proponents of classical economic thought (Canterbery 11). The Great Recession “exposed the inadequacies of the theoretical foundations of the classical laissez-faire doctrine” (Dwivedi 13). At the time of Great Depression, there was unbelievably massive and high level of unemployment in almost all free-market industrial economies (Dwivedi 13). The Gross National Product (GDP) of such nations declined catastrophically (Dwivedi 13). For example, in the United States, the level of unemployment increased from 1929 3 percent to 25 percent level in 1933. Production level (of goods and services) fell by 30 percent while price level declined by 23 percent with business level falling to almost zero level (Dwivedi 13). According to Dwivedi, “the classical economics could offer neither an explanation nor a solution to the economic problems created by the Great Depression” (Dwivedi 13). Needless to say the Great Depression of 1930s brought down the classical macroeconomics. The Keynesian Revolution Following the downfall of classical econ ...Download file to see next pagesRead More

Main Ideas of the Politics of Representation

The reason for phenomenon is that art is not static, but rather interactive with its audience and the political and social ideas of the audience’s present as well as the symbols inherent in the particular forms used. The postmodern movement, with its emphasis on illuminating the sublime, brings these ideas to the forefront. “The political and the aesthetic are inseparable, simultaneously present, faces of the postmodern problematic” (Burgin, 1982). On examining the main ideas within the politics of representation I will draw on various philosophical ideas in relation to recent art practices and consider the topical question of visual representation as an instrument of control and power.

Evolution of the Law and Judicial Activism

In some instances, such fault had been the consequence of the inattention of the defendant. Accordingly, the courts associate fault with intentional offenses or carelessness of the parties involved. Moreover, courts determine the application of fault on wrongdoings or torts. Civil law determines fault in actions of parties where they had exercised less than reasonable care. This insufficient reasonable care would be sufficient to establish a prima facie fault. Previously, the courts had adhered to the principle of there being no liability without fault. Accordingly, a person could be held liable, only if he had committed some fault. This made it essential for a fault to exist. However, the commitment of a fault was not always suff...

The Evolution of a Multi-faceted VET Practitioner

It all depends on the kind of training asked for. In the past, the Technical and Further Education (TAFE) fielded practitioners to groups needing trainers. However, currently, agencies and various groups have developed their own pool of VET trainers.

VET practitioners, in order to be efficient, need to be patient and compassionate to those they serve. Flexibility to adjust to their students or various circumstances is also key. Ethical awareness and recognition of the equality of educational provision reflect a commitment to education. Socially, having a healthy respect for individual differences and knowing when to give merit to those deserving of it earns them the trust of others. Their self-confidence, openness, and...

The Evolution of Human Resource Management

The employee was sent to HR for a final briefing where he mentioned that he had been requesting a change in the shift for the last few weeks he has to attend to his ailing father. His superior continuously ignored the request. The employee was skill and aptitude tested and reassigned to a different project.
This is a small incident where an HR professional can play a vital role. An organization is also constantly looking for such solutions from its Human Resource Department. It is this expertise and skill, which a budding professional from any institute should be equipped.
Such valuable certification programs initiated by the Human Resource Department surely help build a successful organization. The Human resource depart...

The Evolution of Public Media

To instigate one to a category can now just as easily break out into a full-on discussion that may exhaust time and brain cells and yet still remain undefined.
In so much so that censorship and other restrictions, imposed by governments, critiques, audiences and other artists may condone a certain message of restraint that could bring about a new sense or in some cases lack thereof of artistic freedom. It is no longer a matter of identifying the genre and then moving along with the idea. Today’s global world will continue to embark and expand to involve all who are part of this world to be within the grasp of criticism or acclaim.
This categorizing and boxing up is now becoming obsolete as more and more works show...

Evolution of the Concept of Childhood

Philosophers, psychologists and educationists have attempted to approach and analyse the issues of childhood from either their socio-cultural perspectives or from their respective disciplines (Richards & Light, 1986; Burman, 1994a; Woodhead, 1999). A look at the theories suggests that the concept of childhood and the position of children has evolved down the ages into a child or childhood-centric view. In the research works of both Elizabeth Coates from the discipline of Education and Wataru Takei from Psychology, the child-centric model of research is apparent. This aspect of their research has not only made it interesting but at the same time palpable.
Coates’ research on children and their learning response in an...

Macroeconomics and Trade Policys

Keynes argued that prices and wages do not determine the level of employment, as many classical economists suggested, but instead the level of aggregate demand for goods and services (Case & Fair 683). Keynes realized as well during the Great Depression that the government could intervene in the economy to attain specific employment and output goals by either increasing or decreasing taxes and government spending.

For example, raising taxes will decrease the disposable income of households and thus effectively decreasing consumption. When the government decreases consumption, the household demand for goods and services decreases thus it would only seem reasonable that the amount of output that the economy would also...

What Is Macroeconomics

While microeconomics is concerned with the factors underpinning the economic life of individual entities like families and small businesses, macroeconomics looks into the various elements that move or determine the economy in its entirety or what some call an aggregate economy. Macroeconomics is useful because it allows a predictive view of how market forces affect the economy and advises governments appropriate economic policies and gives private individuals and business entities a glimpse of what the future holds economically.
The term macroeconomics did not exist prior to the Great Depression but there was a collective set of theories that were used to study the various workings that influenced the aggregate economy. Econo...

The Evolution of Australia Terrestrial Vertebrates

Marsupial species including diprotodons and a giant reptile, the Megalania, a goanna species measuring up to 7 meters in length, disappeared within a relatively short time. Australia suffered greater extinction rates than other continents with an estimate of over 85% of all vertebrates over a bodyweight of 40 kilograms becoming extinct (Roberts et al, 2001).
Australian megafauna during the Pleistocene included marsupial mammals, birds, and reptiles, with marsupial herbivores weighing up to 1,500 kilograms. Kangaroo species reached weights of up to 1,000 kilograms and the largest bird, Geyornis newton, weighed an estimated 100 kg (Hiscock, 2008).
The tendency to evolve into larger species (gigantism) is a product of natur...

Intermediate Macroeconomics and Macroeconomic Coordination

...CHAPTER 04 (MACROECONOMIC COORDINATION) We know that when GDP, APE & ASF are unequal, than an interplay occurs (Macroeconomic coordination process) which bridges the gap between these variables. If there is a disparity between ADF & ASF, there will be an automatic reaction among money users & suppliers which restores the magnitude of these variables to equality generally known as funding adjustment. Similarly, if there is a difference in the values of GDP & APE, it will trigger the suppliers of goods & services to act together and bring the figure close to equality. This process is called output-price adjustment. The purchasers of the domestic output can be classified into three groups. Group 1 involves individuals having sufficient money...
