What causes economic growth in the LR?

The Long run trend rate of economic growth measures the average sustainable rate of economic growth over a period of time.
The Long Run trend rate will depend upon the growth of productive capacity in the economy and therefore the growth of LRAS. The below diagram shows an increase in LRAS and therefore an increase in potential growth:
Diagram: Long Run Economic Growth

The growth of potential output could increase due to 2 main factors: * 1. An increase in resources land, labour and capital * 2. An increase in the efficiency of these resources i.e. improved labour or capital productivity.
Firstly if there is improved technology, e.g if robots were used more effectively in factories, this will enable higher output and lower costs. An important factor is labour productivity; if there is improved education and training then workers will be more productive and this will increase the LRAS.
If the country had an increase in Raw materials e.g. finding a new source of oil this would increase LRAS.
Also, if there is an increase Capital, such as, investment in new factories and machines LRAS will increase.
The growth rate could increase if there was an increase in the size of the labour force. This could caused by higher population growth or an increase in the participation rate.
The Long run trend rate could be increased by successful government supply side policies. Supply side policies attempt to increase productivity in the economy through greater efficiency and productivity. For example, in the UK Supply side policies have involved privatisation and reducing the power of trades unions. Supply side policies can be either, free market, or interventionist. Privatisation is an example of a free market policy because it increases efficiency by removing the role of government in industries. It is argued the private sector are more efficient because they have a profit motive. This increased efficiency can increase long run growth

...conclusions together to formulate his strategic plan. (2) If McGraw chooses a strategic direction that favors only one department, what negative effects could this have on other departments? How can McGraw mitigate the damage? If McGraw would use a strategy that favours only one department, the brands of the other departments would lose. Sales for the other divisions would also decline probably causing a consequent collapse and closure of these divisions as suggested by Eric Stanger, VP on OM products. The foundation of the OM brand, for example was eroding rapidly due their attempt to underwrite the new line of LR trademarks. It would also cause a slippage in value and trust among their customer franchise and a decline in sales and share. To mitigate the damage, McGraw would also need to pump finance into the advertising and promotion of the other divisions and not only LR or any other single division, for that matter.

The Effects of Macroeconomic Evils on Property and Violent Crimes in Malaysia

...Recent deliberation on whether “Malaysia is a safe haven for travel and investment?” was frequently asked by the international tourists and foreign investors owing to the increasing trend of crime rates in Malaysia. From the visual inspection in Figure 1, both property and violent crime rates in Malaysia has increased quite significantly between 1970 and 2006. Over a decade from 1970 to 1980, both property and violent crime rates in Malaysia increased more than two folds. The property crime rate increased drastically from 25 thousand cases in 1970 to 66 thousand cases in 1980. In the similar vein, violent crime rates increased from approximately 3 thousand cases in 1970 to approximately 8 thousand cases in 1980. During the period of economic recession in the 80s (see Figure 1), the property crime rate dropped about 36 per cent and the violent crime rate reduced about 8 per cent over the period of 1980 to 1989....

The topic given me is current, topical and emotional. Food prices are always controversial, either too high for consumers or too low for farmers and often unstable. The paper is divided into four parts: the first places the current situation in historical context; the second identifies some competing explanations for high food prices; the third analyzes in more detail the Structural Change/Shock story; and the fourth notes the consequences, especially for Developing Countries. The paper closes with the big question - When the bubble breaks, will long run real prices be on a higher level with a stable or increasing trend or will we back to “Business as Usual” with real prices dropping down to the previous level and continuing their 150 year downward trend? THE CURRENT SITUATION IN HISTORICAL CONTEXT FAO’s price index of all foods in dollar terms has more than doubled since last three years of the 20th century, and the real food price index has increased by over sixty percent (Figure 1.).

...7/7/2014 Evernote Export Modern Welfare Criteria Created: 5/22/2012 9:12 PM General Equilibrium and Perfect Competition General Equilibrium of Exchange and Consumption 1. We assume that there is no production and the economy is a pure exchange economy. There are 2 individuals and 2 goods, who will exhaust the goods together. Naturally they will consume until (MRS x,y )A = (MRS x,y )B. But we don't know beforehand what will be the exact equilibrium. But if we know the initial distribution, we can define the boundary within which the equilibrium solution will lie. 2. Thus the initial distribution of goods and their relative bargaining strengths will determine the equilibrium position. This general equilibrium determines not only the final distribution of goods but also the rates of exchange or relative prices. Note that however, we can't determine absolute prices from here, we can only determine relative prices. Show that in PC, General Equilibrium can exist 1. This ca be shown using the fact that under PC, relative prices which A is facing will be same as relative prices which B is facing and hence MRS x,y for both will be same. General Equilibrium of Production 1. We assume that all labor is homogenous, receives equal wages, total quantity of each factor (L and K) is fixed, the production function is continuous and twice differentiable and the technology is given which together with factor endowments limits the production possibilities.

S. Sujit1 and B. Rajesh Kumar2 Abstract: The dynamic and complex relationship among economic variables has attracted the researchers, policy makers and business people alike. This study is an attempt to test the dynamic relationship among gold price, stock returns, exchange rate and oil price. All these variables have witnessed significant changes over time and hence, it is absolutely necessary to validate the relationship periodically. This study takes daily data from 2nd January 1998 to 5th June 2011, constituting 3485 observations. Using techniques of time series the study tried to capture dynamic and stable relationship among these variables using vector autoregressive and cointegration technique. The results show that exchange rate is highly affected by changes in other variables. However, stock market has fewer roles in affecting the exchange rate. In this study we tested two models and one model suggests that there is weak long term relationship among variables.

...certain reforms under a new reform minded administration. Prior to the present democratic rule, Nigeria's former military rulers failed to diversify the economy away from its overdependence on the capital-intensive oil sector, which provides 20% of GDP, 95% of foreign exchange earnings, and about 80% of budgetary revenues. The largely subsistence agricultural sector has failed to keep up with rapid population growth - Nigeria is Africa's most populous country - and the country, once a large net exporter of food, now must import food. Following the signing of an IMF stand-by agreement in August 2000, Nigeria received a debt-restructuring deal from the Paris Club and a $1 billion credit from the IMF, both contingent on economic reforms. Nigeria pulled out of its IMF program in April 2002, after failing to meet spending and exchange rate targets, making it ineligible for additional debt forgiveness from the Paris Club. In 2003, the government began deregulating fuel prices, announced the privatization of the country's four oil refineries, and instituted the National Economic Empowerment Development Strategy. In November 2005, Abuja (the federal capital territory) won Paris Club approval for a debt-relief deal that eliminated $18 billion of debt in exchange for $12 billion in payments - a total package worth $30 billion of Nigeria's total $37 billion external debt. The deal requires Nigeria to be subject to stringent IMF reviews. GDP rose strongly in 2007,...

Electricity Demand Side Management (Dsm) in India – a Strategic and Policy Perspective Electricity Demand Side Management (Dsm) in India – a Strategic and Policy Perspective Electricity Demand Side Management in India

...ELECTRICITY DEMAND SIDE MANAGEMENT (DSM) IN INDIA – A STRATEGIC AND POLICY PERSPECTIVE S. PADMANABAN & ASHOK SARKAR Office of Environment, Energy and Enterprise US Agency for International Development, New Delhi, India. Overview The Indian power sector has more than tripled its installed capacity, from 30,000 MW in 1981 to over 100,000 MW in 2001. Despite this growth in supply, its power systems are struggling to overcome chronic power shortages and poor power quality. With demand exceeding supply, severe peak (around 18%) and energy (around 10%) shortages continue to plague the sector. Shortages are exacerbated by inefficiencies in power generation, distribution and end-use systems. The inefficiencies in the end-use systems is due to irrational tariffs, technological obsolescence of industrial processes and equipment, lack of awareness, nascent energy services (ESCO) industry, and inadequate policy drivers (such as energy efficiency standards and labeling system, financial incentives) in India. The elementary problem being faced by the power sector is the poor financial conditions of the State Electricity Boards (SEBs) or successor entities in most states. Over the years, the SEBs have been causing an increasingly larger drain on the State Government budgets, contributing to 10-15% of the state fiscal deficits adversely impacting much needed investments in the social sectors of health and education. The power sector is operating with very low or no returns...

Malnutrition: a Major Threat

...affecting our economy. This paper will illustrate the impact of malnutrition on businesses and economies, and how it has altered my outlook towards life. Malnutrition is not only an urgent global health issue; it is also a hitch to productivity, economic growth and poverty reduction. We again end up asking the unchanged question, who is responsible? Definition UNICEFii defines malnutrition as a broad term commonly used as an alternative to undernutrition but technically it also refers to overnutrition. People are malnourished if their diet does not provide adequate calories and protein for growth and maintenance or they are unable to fully utilize the food they eat due to illness (undernutrition). They are also malnourished if they consume too many calories (overnutrition). Words like GDP and GNP which was covered in the class, provided me with a different perspective to the situation. I took time to review the effect of malnutrition in my country, India. I found that malnutrition was causing a loss as high as 3 to 4% to my country’s growing GDPiii. Even though the overall GDP of the country has been rising, the amount of loss caused by malnutrition is also increasing. Effect of Malnutrition on Economy  Malnutrition indicates poor economic policies of the country, deprived agricultural conditions and also...

The study aimed to test and confirm the effectiveness of the common determinants of commercial banks lending behaviour and how it affects the lending behaviour of commercial banks in Nigeria. The model used is estimated using Nigerian commercial banks loan advance (LOA) and other determinants or variables such as their volume of deposits (Vd), their investment portfolio (Ip), interest (lending) rate (Ir), stipulated cash reserve requirements ratio (Rr) and their liquidity ratio (Lr) for the period; 1980 – 2005. The model hypothesizes that there is functional relationship between the dependent variable and the specified independent variables. From the regression analysis, the model was found to be significant and its estimators turned out as expected and it was discovered that commercial banks deposits have the greatest impacts on their lending behaviour. The study then suggests that commercial banks should focus on mobilizing more deposits as this will enhance their lending performance and should formulate critical, realistic and comprehensive strategic and financial plans. Keywords: Lending, Deposits, Investment, Portfolio, Liquidity, Solvency, Interest rate. 1. Introduction Lending which may be on short, medium...
