Organizational change typology of evolutionary and strategic changes

Organizational change typology of evolutionary and strategic changes Introduction: This assignment examines organizational change, focusing on the distinction of changes according to their scope and presenting a typology of evolutionary and strategic changes. Business in the new millennium will continue to increase in intricacy. More and more, this demanding environment forces executives and managers to deal with constant change. Globalisation, increased opposition, international development and reformation are just a few of the challenges faced daily. Success in dealing with these new challenges will depend to a great extent on the organisation’s ability to change and adapt. It will depend on how well these organisations can manage these situations by understanding the opportunities and challenges that accompany it. The organisations that will succeed are those that recognise and react the fastest to change. Therefore, the ability of an organisation’s staff to change can mean the difference between scraping just to get by or else becoming the industr y leader. In either case the results translates into millions of dollars in revenues, profits, or losses. It must therefore be accepted that change is an organisational reality. It is critical therefore for managers and executives in todays business environment to be equipped with the skills necessary to manage change. Ultimately it is people who make organisations, and if they do not change, then there is no organisational change. The challenge therefore is for managers and executives to not only know what to change but how to go about it especially in relation to people, products, processes and systems, marketing strategies etc. Just like the butterfly, organisations will have to change and undergo a metamorphosis before they can fly. If they do not, they will be doomed to live out their lives only as caterpillars, or worse still become dinosaurs. Litrature Review: Organizational change is an empirical observation in an organizational entity of variations in shape, quality or state over time (Van de Ven and Poole, 1995), after the deliberate introduction of new ways of thinking, acting and operating (Schalk, Campbell and Freese, 1998). The general aim of organizational change is an adaptation to the environment (Barr, Stimpert and Huff, 1992; Child and Smith, 1987; Leana and Barry, 2000) or an improvement in performance (Boeker, 1997; Keck and Tushman, 1993). This definition encompasses many situations that should be distinguished by applying certain dimensions to establish ‘typologies of change’. We will refer to the scope of change, because it is one of the most used variables in literature to design change typologies. That way, changes can be defined along a continuum starting in lowscope or evolutionary changes to high-scope or strategic ones. With the aim of making the use of this dimension (scope) easier, we will describe bot h extremes of the continuum, but we should always keep in mind that real changes are not a pure type but a mixture. First, we will describe evolutionary, incremental, or first order changes. These are small changes that alter certain small aspects, looking for an improvement in the present situation, but keeping the general working framework (Blumenthal and Haspeslagh, 1994; Goodstein and Burke, 1991; Greiner, 1972; Levy, 1986; Mezias and Glynn, 1993; Nadler and Tushman, 1989; 1990). The second type of changes arestrategic, transformational, revolutionary or second order ones. They are radical transformations, where the organization totally changes its essential framework (Blumenthal and Haspeslagh, 1994; Ghoshal and Bartlett, 1996; Goodstein and Burke, 1991; Marshak, 1993; Nadler and Tushman, 1989, 1990), looking generally for a new competitive advantage (Hutt, Walker and Frankwick, 1995) and affecting the basic capabilities of the organization (Ruiz and Lorenzo, 1999). Background to Change exits in HP Economic Movement: Managing change is one of the most important issues confronting information technology (IT) organizations today. By combining three powerful products—HP Service centre software, HP Change Control Management software and HP Universal Configuration Management Database (CMDB) software—HP Change Management Suite software gives IT managers, changer managers and change advisory boards (CABs) a complete solution for managing change within an IT environment. This tightly integrated solution enables IT departments to gain visibility into the IT environment and service dependencies, and manage the change process in a standardized manner to increase the number of effective, well-founded changes their companies undertake. It also provides decision support for the CAB by auto mating impact analysis to make change decisions based upon business impact and mitigates the risks inherent in instituting change. Strengths and Weaknesses of Change within an organisation in regards to HP: Strengths: Sole point of contact, high market consciousness, easier for customers to deal and cooperate. Easier to preserve functional skill, staffs tends to be more loyal to occupation, frequently has lower cost at the unit level. Highly combined work units, integrated functions, and backup skills. Easier harmonization, determined on the customer, more supple, minimal isolation, flatter, staff gain broader information of the business. Federal responsibility, higher quality, faster decision making, focused on the customer of each product/service group. Flexible resource planning, high practical knowledge exposed to diversity, forced collaboration service areas. Weaknesses: Less contribution/higher costs, more product or service changeability. Tends not to have end-to-end customer sight, practical priorities sometime are contradictory, more difficult to transform processes due to isolation of functions. Some laying-off of functions, lower sense of useful responsibility. Difficult to put into practice and maintain, requires cross functional expertise, long term management commitment. Comparison of alternative forms of organisational development: Digital change and organisational Development: It is been investigated the determinants of local governmental presence and the influence of organizational presence using econometric scrutiny, supported by qualitative information from the review. The variables included in these regressions and the hypotheses about the impacts of explanatory variables are discussed in a later section. In all regressions, the coefficients and standard errors were corrected for sampling weights, stratification, and the total number of communities in the central region (StataCorp 1997). The results are thus agent of the province as a whole. Standard mistakes were approximate using the Huber-White estimator, and are thus robust to general forms of heteroskedasticity (White 1980). A pathways of enlargement found in the region, were included as descriptive factors in the analysis (along with other factors).10 A development pathway is defined as a common prototype of change in livelihoods and resource management, and thus represents a particular set of ec onomic opportunities and constraints (Pender, Scherr, and Duron 1999). Using data on occupations and changes in profession and land use since the mid-1970s, six pathways of development were acknowledged. Basic grain (maize, beans and sorghum) production is the most or second most important profession in all but one of the sample communities. Other factors were therefore more determinate in characteristic the pathways. The pathways include villages where 1) basic grain production is the dominant economic activity and has been expanding during the past 20 years (basic grains expansion pathway), 2) basic grains production is the dominant economic activity though production has been sluggish or failing (basic grains stagnation pathway), 3) horticultural (mainly vegetable) production has amplified and has become the first or second most important activity (horticultural expansion pathway), 4) coffee production has increased and is the first or second most important activity (coffee expan sion pathway), 5) forestry performance are the first or second most important activity (forestry specialization pathway), and 6) non-farm employment has increased and become the first or second most important source of income (non-farm employment pathway). Involvement of Stakeholders in the Introduction of Change in an Organisation: Stakeholders, including NGOs, investors, and activists, as well as communities, labour, and consumers, are playing an increasingly important role in improving corporate behaviour. Some NGOs are using tactics of direct confrontation. Others have been working for years to create partnerships with companies in order to help them green their production, often in ways that actually save them money. As well, the investor community is taking an increasingly active role in encouraging corporations to consider not just the next quarter’s earnings but also the long-term financial risks of failing to address broader social and environmental issues. Together, these are proving key strategies in compelling corporations to internalize the environmental and social costs that are often ignored in the mad race for profit. Analysis and Evaluation of the Strategies: Corporate managers face many daily pressures, and improving social and environmental records (often in ways that don’t directly enhance the bottom line) is not generally their highest priority—until their corporations suddenly become the targets of bad publicity from a coordinated group of activists. With corporations spending a half trillion dollars each year to create positive images through advertising, a sudden storm of negative publicity from the actions of thousands of coordinated activists can swiftly raise environmental issues to the top of managers’ action-item lists. This fear of public shaming—and the connected loss of profit and stock value—are what makes these â€Å"corporate campaigns† so successful. Unlike traditional campaigns against companies, such as boycotts, labour strikes, and litigation (which remain important but often have limited objectives), corporate campaigns treat the targeted company more as a lever of change th an as an end in itself. When a coalition of NGOs and investors led by the Rainforest Action Network (RAN) targeted Citigroup, the goal was to reduce overall exploitation of natural resources. But RAN didn’t target mining and logging companies—which are not in the public eye and depend on continued extraction to survive—pouncing instead on the financial institutions that capitalize the mining and logging companies. Unlike them, banks spend billions to maintain strong brands and customer bases. These assets are essential, and thus exploitable vulnerabilities.And exploit RAN did. In 2000, RAN asked Citigroup to adopt a green lending policy.While the company initially refused, after more than three years of protests, shareholder actions, and other irritating tactics, Citigroup finally recognized that lending to unsustainable industries would be more costly than profitable, while not lending to them would be worth its weight in free advertising. Once Citigroup yielde d, its antagonistic relationship with RAN evolved into a collaboration to ensure adherence to its new standards—a partnership that provided much free publicity to Citigroup. Meanwhile, RAN quietly drafted a letter to Bank of America asking managers to adopt a similar policy. Bank of America, having witnessed the disruption that committed activists can cause by chaining themselves to bank doors, quickly realized that it was better to join the ranks of ecofriendly banks. Bank of America’s capitulation then left JPMorgan Chase as the next target, and it soon followed suit. Conclusion: It can be argued that the booming management of change is vital to any organisation in order to endure and succeed in the present highly economical and endlessly evolving business environment. However, theories and approaches to change management currently available to academics and practitioners are often clashing, mostly deficient pragmatic evidence and supported by undisguised hypotheses concerning the nature of fashionable organisational change management. The reason of this assignment was, therefore, to provide a significant review of some of the main concepts and methodologies to organisational change management as an important initial step towards implementing a new framework for managing change.

Dracula and Kenneth Essay

The high angle shot and extreme long shot looking down at Dracula and Harker crossing through the hall. This shot draws attention to Dracula’s extremely long red cape streaming out behind him like a trail of blood. The low angle shot shows Dracula looming over Harker and makes him look powerful, like he is in control. Many two shots are used to allow the audience to make comparisons between the two characters. The low angle shot is also used to emphasize the shadow’s movements. The low lighting helps with casting Dracula’s shadow which is again typical of horror. Dracula’s eerie shadow moving in the gloom is very effective for scaring the audience as the combination of shadow with candle light works exceptionally well for this scene. This candle light makes the gloomy aspect more present as the castle is immense and there are not very many candles so most of the entrance hallway would be beyond the reach of the light and in darkness, which makes it very scary as you do not know what lurks in the gloom. There is orchestral music played by the strings which go low and slow to create a sinister atmosphere. This music adds to the feeling of tension, the feeling that something is going to happen. The music gets louder and quicker when Harker offends Dracula by laughing and Dracula gets furious and pulls out a sword. This combined with the change of pace and volume of the music makes the audience become afraid, a typical trick of horror. There are many different sound effects in this scene from Dracula. There is the howling of the savage wolves, which scares the audience and makes the element of horror and wildness of the setting more clear. There was the thunder, which is typical of a horror movie. The clanging of the huge, metal gates emphasizes the feeling of the strength and inescapability of the castle and that Harker will not be able to escape and this will be his prison for the rest of his life. Harker’s costume is typical of a man of those times. He wears a suit and is very neatly presented. He has his hair combed very carefully. Dracula’s is very different. He wears a huge red robe which trails out behind him like blood. His hair is curled up high and is white and it mixes with the skin on the back of his neck which makes him look weird and scary. His skin is white and wrinkled like an old man and this creates the effect that he has been drained of all his blood and that helps you to understand his lust for blood and the way he talks about the preciousness of blood. It makes him look very scary and effective, almost dead in a way. It also makes him look exotic and abnormal. He would stand out in a crowd of normal people. There were quite a few similarities between the film extract and the text; both were set in a huge, Gothic castle with a vast courtyard. The stone was ‘massively carved’ and the door was old and studded. Both had creeping shadows and lanterns. In both the film extract and the text, Dracula is portrayed as having hairy palms (abnormal), profuse hair, an â€Å"extraordinary pallor† as he is very pale, he is portrayed as being an old man in both and he is also similarly portrayed as speaking with a ‘strange intonation’ (foreign accent). The similarities between the film extract and the text with Harker is that in both they portray his feelings of anxiety and his crossing of the threshold is made significant. The differences are that in the text, Dracula is described as having bushy eyebrows and a moustache whereas in the film extract he has a plain face. In the text, Dracula is dressed in all black while in the film he is dressed in white which emphasizes his paleness with a red cape that is more powerfully visual as looking like blood flowing behind him. Also in the text Dracula is portrayed as having a red mouth with protuberant, pointed teeth while in the film he is shown as having a pale mouth and normal teeth. The director uses this look in order to make Dracula look like a normal human, adding to the feeling of mystery surrounding him, and to make him different from the stereotypic image of Dracula. Summary These two films engage a modern audience in the way the films use clever tricks to give suspense, which can be overlooked in some of the newer horror films that rely on the amount of blood that comes out rather than clever filming and jumpy moments. In short, Dracula and Frankenstein were very similar in the way that they portrayed the typical horror tricks and consisted of similar camera angles to each other point out various bits. I thought that Dracula, both the written extract and the film extract fitted the horror genre a bit better than Frankenstein as it was more believable for me. I also thought that the film extract was much more scary, although Frankenstein wasn’t bad and had its moments of fright. My final views were that Dracula was on the whole filmed better than Frankenstein as it used the different camera angles more effectively in my opinion.

Animal Testing Should Be Banned - 1300 Words

In today’s cosmetics industry, many ordinary animals, such as dogs, cats, rabbits, and monkeys, are being subjected to animal testing on products that could potential benefit a person’s complexion. Such animals are often chosen, because their DNA is genetically very similar to humans, and thus could be used for testing. The extensive procedures to testing various merchandises could potentially harm the animals during the process, because there are multiple trials to see whether or not the product is safe to use on humans. Of these trials, many animals suffer from intensive allergic reactions that could have long-term affects on them or potentially kill them. American cosmetic industry today are harming innocent animals, specifically rabbits, through testing procedures and instead should be using human cells to make synthetic cells that could be tested on rather than on live animals. Laboratory rabbits are being abused to fit the needs of the cosmetic industry. In skin i rritation experiments, the rabbit’s back are shaven and cosmetic ingredients are applied to the raw skin. The rabbits are not given any pain relief to these toxic chemicals that will often burn the skin, and thus leading to tissue damaged. Once the experiment is over, the rabbits are killed. Also, rabbits are subject to eye irritation experiments. John H. Draize, Ph.D, is a scientist at the United States Food and Drug Administration (FDA).

In the mean time, I am able to gain computer skills during the studies because computers are the only tool to run analysis and tweak components or electrical circuits. Consider that the modern world is run by computers, I am sure that having great computer skills will be the most advantage of having a job in the future. The biggest benefit of having electrical engineering is surely the increase of the job opportunity. Although there are various of jobs are provided to the electrical engineers, the types and details of jobs are still unclear. As I mentioned earlier, electrical engineers are extremely versatile because the work can be related with many engineering disciplines or natural science disciplines.

Malcolm X As Notorious For The Fear He Caused White America

Malcolm X is unjustly viewed as notorious for the fear he caused White America. The controversy he caused was bigger than ever before, and most of his simple actions were skewed and twisted by the media. Malcolm X grew up persecuted by what was America and stayed persecuted as he fought against the systematic oppression that based the way the U.S treated African-Americans. Malcolm X (also known as Malcolm Little or El-Hajj Malik El-Shabazz) was born May 19th 1925 in Omaha, Nebraska. He was born to the parents Earl Little, and Louise Norton Little. Earl Little was a carpenter, but his reputation to the town came from him being a civil rights activist and outspoken member of the MGUNIA, or the Marcus Garvey Universal Negro Improvement Association. Earl followed closely with the beliefs and ideas of Marcus Garvey, who was a black separatist, which caused Earl to get death threats from racist organizations such as Black Legion and the Ku Klux Klan. Despite his efforts to elude the threat s, in 1929, his enemies prevailed and burned their Lansing, Michigan home to the ground. Two years after, Earl’s body was found on the trolley tracks of Lansing. He died shortly after he was found.

Light Reactions and Plant Pigments Free Essays

The Effect of Light Reactions on Plant Pigmentation Alyssa Martinez AP Biology 4th pd E. Perkins Abstract In this lab, we were to separate pigments and calculate Rf  values using plant pigment chromatography, describe a technique to determine the photosynthetic rate, compare photosynthetic rates at different light intensities using controlled experiments and explain why rate  of photosynthesis varies under different environmental conditions. In the second part of the lab, we used chloroplasts extracted from spinach leaves and incubated then with DPIP and used the dye-reduction technique. We will write a custom essay sample on Light Reactions and Plant Pigments or any similar topic only for you Order Now When the DPIP is reduced and becomes  colorless, the resultant increase in light transmittance is measured over a  period of time using a spectrophotometer. If pigments are separated, then Rf values can be determined. Introduction Paper chromatography is a  useful technique for separating and identifying pigments and other molecules from cell extracts that contain a  complex mixture of molecules. As solvent moves up  the  paper, it carries along any  substances dissolved in it. The more soluble, the further  it travels and vice-versa. Beta carotene is  the most abundant carotene in plants and is  carried along near the solvent front since it is very soluble and  forms no hydrogen bonds with cellulose. Xanthophyll contains oxygen and is found further from the solvent front since it  is less soluble in the solvent and is  slowed down by hydrogen  bonding to cellulose. Chlorophyll a is  primary photosynthetic pigment in plants. Chlorophyll a, chlorophyll b, and carotenoids capture light energy and transfer it to  chlorophyll a at the reaction center. Light is  part of a continuum of radiation or energy waves. Shorter wavelengths of energy have greater amounts of energy. Wavelengths of light within the visible spectrum of  light power  photosynthesis. Light is absorbed by leaf  pigments while electrons within each photosystem are boosted to a higher energy level. This energy level is  used to produce ATP and reduce  NADP to NADPH. ATP and  NADPH are then used to  incorporate CO2 into organic molecules. In place of  the electron accepter, NADP, the compound DPIP  will be substituted. It changes chloroplasts from blue to colorless. Methodology Obtain a 50 ml graduated cylinder which has about 1 cm of solvent at the bottom. Cut a piece of  filter paper which will be long enough to reach the solvent. Draw a line about 1. 5 cm from the bottom of the paper. Use a quarter to extract the pigments from spinach leaf cells and place a small section of leaf on top of the pencil line. Use the ribbed edge of the coin to crush the leaf cells and be sure the pigment line is on top of the pencil line. Place  the chromatography  paper in the cylinder and cover the cylinder. When the solvent is about 1 cm from the top of the paper, remove the paper  and immediately mark the location of the solvent front before it evaporates. Mark the bottom of each pigment band and measure the distance each pigment migrated from the  bottom of the pigment origin to the bottom of the separated pigment band and record the distances. Then, turn on the spectrophotometer to warm up the instrument and set the wavelength to 605 nm. Set up an incubation area that  includes a light, water flask, and test tube rack. Label the cuvettes 1, 2, 3, 4, and 5, respectively. Using lens tissue, wipe the outside walls of each cuvette. Using foil paper, cover the walls and bottom of cuvette 2. Light should not  be permitted inside cuvette 2 because it is a control for this experiment. Add 4 mL of distilled water to cuvette 1. To 2, 3, and 4, add 3 mL of distilled water and  1 mL of DPIP. To 5, add 3  mL plus 3 drops of distilled water and 1mL of DPIP. Bring the spectrophotometer to zero by adjusting the amplifier control knob until the meter reads 0% transmittance. Add 3 drops of unboiled chloroplasts and cover the top of cuvette 1 with Parafilm and invert to mix. Insert cuvette 1 into  the sample holder and adjust the  instrument to 100% transmittance. Obtain the unboiled chloroplast suspension, stir to mix, and transfer 3 drops to cuvette 2. Immediately cover and mix cuvette 2. Then remove it from the foil sleeve and  insert it into the spectrophotometer’s sample holder, read the percentage transmittance, and record it. Replace cuvette 2 into the foil sleeve,  and place it into the incubation test tube rack and turn on the flood light. Take and record additional readings at 5, 10, and 15  minutes. Mix the cuvette’s contents before each reading. Take the unboiled chloroplast suspension, mix, and transfer 3 drops to cuvette 3. Immediately cover and mix cuvette 3 and insert it into the spectrophotometer’s sample holder, read the percentage transmittance, and record. Replace cuvette 3 into the incubation test tube rack. Take and record additional readings at 5, 10, and  15 minutes. Mix the cuvette’s contents just prior  to each readings. Obtain the boiled chloroplast suspension, mix, and transfer 3 drops to cuvette 4. Immediately cover and mix cuvette 4. Insert it into the spectrophotometer’s sample holder, read the percentage transmittance, and record it. Replace cuvette 4 into the incubation test tube rack and take and record additional readings at 5, 10, and  15 minutes. Cover and mix the contents of cuvette 5 and insert it into the spectrophotometer’s sample holder, read the percentage transmittance, and  record. Replace cuvette  5 into the incubation test tube rack and take and record additional readings at 5, 10, and 15 minutes.

This can be used to identify the pigments that are used in the  process of  photosynthesis. Photosynthesis is the process by which plants use light energy to produce chemical  energy in the form of food. This is where plant pigments come into play because they are the reason why the plant is able to absorb light. Chlorophyll a is one such  pigment. These pigments along with many others are contained in organelles known as chloroplasts. One of the problems encountered during the course of this lab included human error when using the spectrophotometer. The student made slight errors when setting the transmittance to the required levels. On a few occasions, the group accidentally introduced light into a cuvette where the variable being tested was the absence of light. This might have caused some error when taking measurements of the percentage  of transmittance. This resulted in skewed data, which meant that the experiment had to be repeated once more. During the first part of the  lab, the group made an error by allowing some part of the pigment  to be in the solvent. This did alter our results in the end. Topics for Discussion 4A: Plant Pigment Chromatography 1. What factors are involved in the separation of the pigments? The factors involved in the separation of the  pigments  from the  spinach plants  are the pigments’ solubility in the solution, how much they bind to the paper based on their chemical structure, and the size of the pigment particles. . Would you expect the Rf value of a pigment to be the same if a different solvent were used? Explain. No I would not expect the Rf values to be different because the pigments will dissolve differently in different types of solvents. For example, chlorophyll b is very soluble in hydrophobic solutions, so if the crushed spinach cells on the paper were put in a hydrophobic s olution, the chlorophyll b would move the highest and probably be right on the solution front, while the other pigments will move much less. 3. What type of chlorophyll does the reaction center contain? What are the roles of the other pigments? Chlorophyll a is in the reaction center, and the other pigments are able to absorb light from the other wavelengths that chlorophyll a cannot absorb light from, and then they transfer the energy harvested from the other wavelengths to the chlorophyll a, providing more energy to be used in photosynthesis. 4B: Photosynthesis/The Light Reaction 1. What is the function of DPIP in this experiment? DPIP is the electron acceptor in this experiment (instead of NADP which is what is normally used in plants). The electrons boosted to high energy levels will reduce the DPIP, which will change its color from blue to clear as more high energy electrons are absorbed by it. 2. What molecule found in chloroplast does DPIP â€Å"replace† in this experiment? It replaces NADP molecules that are found in chloroplasts. 3. What is the source of the electrons that will reduce DPIP? The electrons come from the photolysis of water. 4. What was measured with the spectrophotometer in this experiment? The light transmittance was measured, which really was the measure of how much the chloroplasts reduced the DPIP 5. What is the effect of darkness on the reduction of DPIP? Explain. Darkness will restrict any reaction to occur. 6. What is the effect of boiling the chloroplasts on the subsequent reduction of DPIP? Explain. By boiling chloroplasts, we denature the protein molecules, ending the reduction of DPIP. 7. What reasons can you give for the difference in the percent transmittance between the live chloroplasts that were incubated in the light and those that were kept in the dark? The percent transmittance grew to steadily higher numbers as the experiment progressed because the light reaction was able to occur. However, the dark cuvettes had stable levels of transmittance because light is necessary to excite electrons, which, in turn, reduces the DPIP. 8. Identify the function of each of the cuvettes. Cuvette 1: Used as the control Cuvette 2: Used to observe the rate of photosynthesis without light Cuvette 3: Used to observe the rate of photosynthesis with light Cuvette 4: Used to observe the rate of photosynthesis in boiled chloroplasts Cuvette 5: Used to observe the rate of photosynthesis How to cite Light Reactions and Plant Pigments, Papers

Economic Equilibrium System of Markets - MyAssignmenthelp.com

Question: Discuss about the Economic Equilibrium System of Markets. Answer: Introduction: The term equilibrium stands for equal balance. According to physics, an object is referred to be in the state of balance when two forces of equal magnitude working in opposite direction balance each other. This concept of physics is not limited to it but is also applicable to economics and, the economists term it as equilibrium economics. Equilibrium is a state where any further change is not possible or applicable and two acting forces are not able to influence each other (Ponnusamy, 2017). Stable equilibrium - In stable equilibrium, if the economy of a company gets disrupted due to the change in any of its determining factors, it resumes back to the original point after self-adjustment and the original equilibrium is stored again. There is no net change in the initial and final equilibrium state of the company. This equilibrium can be observed when the demand price is equal to the supply price and there is no tendency of increase in the total amount produced. At this stage, the stable equilibrium is maintained. It can be compared to the pendulum as well which comes back to its original position just after it gets displaced (Conspecte.com, 2017). Concept of Stable Equilibrium In macroeconomics, when aggregate demand = aggregate supply, the stable equilibrium is established for the country. The factors that influence aggregate demand can be written as- C + I + G + Nx = increase or decrease in DD Where, P - price Q - quantity of good S - supply D - demand P0 - price of market balance A - surplus of demand - when PP0 B - surplus of supply - when PP0 In the above plotted graph between Price and quantity of the consumer product. This is a classical stable equilibrium example in economics. SS stands for a positively sloped demand curve and DD stands for a negatively sloped demand curve. Point E is the point of equilibrium where the supply and the demand are balanced. At this point only, OP (the equilibrium Price) and OQ (the equilibrium quantity) are determined. In a case when the supplied quantity is more than the quantity demanded, the surplus quantity will be to the level of AB. This forms a downward pressure on the price in the market. This pressure is kept applied downwards until the state of equilibrium is attained, i.e., the quantity demanded equals the quantity supplied - (Surplus) In a case when supplied quantity is less than the demanded quantity, it leads to shortage of the product in the market. This applies an upward pressure on the price of the product in the market and it pushes up the price to the level of equilibrium where the supplied quantity equals the demanded quantity - (Deficit) (Sharov, 1996) The economy of Australia is quite stable and resilient. It does not face major changes either progressive or regressive and comes back to its original value with minor alterations. Following the trend of GDP growth in Australia from the last 2-3 years, the GDP growth rate has remained to a value between 2.1% to 2.8%. This shows a stable yet growing trend of Australian economy. This stability is due to the following three reasons - housing, shopping, and mining (Jericho, 2016). The economy of Australia hit a recession in 1991 - 92 and from then, Australian economy has been recession free for last 26 years. The Australian economy is the second largest world economy that has not hit a recession for the longest time after Netherlands. The policies of RBA have kept Australia in such intact position. The RBA keeps the likelihood of financial instability reduces by keeping the inflation low (Reserve Bank of Australia, 2017). For this, the bank assesses a diverse range of aggregate economic and financial data to understand the stability of financial system. RBA also ensures the safety of the payment systems. It shares its views with CFR, APRA, and The Treasury on a regular basis. RBA controls the interest rate through its monetary policy. The monetary policy involves setting the interest rates in the market which, in turn, affects the inflation rate. In case of change in the interest rate, RBA controls the supply of the money (Hutchens, 2017). A comparison between interest rate and inflation rate of Australia Year Interest Rate Inflation rate 2012 3.00% 1.8% 2013 2.50% 2.5% 2014 2.50% 2.5% 2015 2.00% 1.5% 2016 1.50% 1.3% Conclusion Australia has maintained a stable equilibrium since the time it last hit recession. The policies designed by RBA are so effective and efficient that control the interest and the inflation rate. The increase in the interest rate eventually leads to inflation and the policies designed by Australian Reserve Bank have coped up with such problems well since last 25 years.
