Economic growth depends on the ability of firms to expand their operations and adopt new technologies
Firms lacking sufficient funds to finance expansions and/or the adoption of new technologies may acquire funds from households through financial system
Financial system: the system of financial markets and financial intermediaries through which firms acquire funds from households.
Economics growth is impossible without a well-functioning financial system.
Financial markets: markets where financial securities, such as stocks and bonds, are bought and sold.
A financial security is a document that states the terms under which funds pass from the buyers of the security (the lender) to the seller (the borrower).

Firms do not receive funds from transactions (交易) in secondary markets.
Another type of financial market is the bond market.
Bond: a financial security that represents a promise to repay a fixed amount of funds
Firms and governments running budget deficits (spending more than they receive in tax revenue) can borrow funds by selling bonds in a primary market.
The seller of the bond promises to pay the buyer of the bond an interest payment each year for the term of the bond as well as a final payment of the amount of the loan (the principal) at the end of the term.
As with stocks, the original buyers

...Running Head: MACROECONOMICS TERM PAPER 1 Macroeconomics Term Paper MACROECONOMICS TERM PAPER 2 Abstract Using the required United States economic indicators the federal government uses to guide the economy, I researched and analyzed each indicator by comparing the data from 2010 to that of 2011. Even though a large number of economists are optimistic, my opinion is that while recovery is progressing, the pace at which we are moving is not fast enough to rejuvenate consumer confidence. Based on what I have read and have learned in the classroom over the last few weeks, I am even more concerned for our future than I was before I started to learn the world of economics. The comparisons of the economic indicators paint a very dismal picture to me. MACROECONOMICS TERM PAPER 3 Gross Domestic Product After learning what the Gross Domestic Product (GDP) is, I better understand the data I researched. Based on what I read on the Bureau of Economic Analysis website, Table 1 – Real Gross Domestic Product and Related Measures, the Gross Domestic Product for June of 2010 (Q3) was 2.5 percent compared to the Gross Domestic Product of 2.0 percent, only a year later in June of 2011 (Q3); a deficit of .5 percent between the two years.

...Fundamentals of Macroeconomics Paper Charles R. Davis Jr. ECO 372 November 12, 2014 Mike Garrison Fundamentals of Macroeconomics Paper The study of macroeconomics examines individuals on a very large scale. Society is constantly changing trends and behaviors that can be interpreted into number results. This paper will focus on and give examples of economic activities, such as purchasing groceries, massive layoffs of employees, and decrease in taxes. All of these things affect the government, households, and businesses in one way or another. Also I will describe the flow of resources from one entity to another for each activity as well as relate at least one current event to the activities. The GDP or the gross domestic product, nominal GDP, real GDP, inflation rate, unemployment rate, and interest rates all affect our economy. These areas will determine the influence over how we purchase groceries, whether layoffs are at an all time high or decrease in taxes. The definition of the GDP is basically the market value of services and goods that are produced in the country at any given time. Real GDP is the measure of the value of economic output that adjusts for price changes. Nominal GDP is a gross domestic product figure that has not been adjusted for inflation. Purchasing Groceries Purchasing groceries helps out mainly the government because of the tax revenue that it brings in. It helps businesses because of the money they receive of your purchase.

...Essay Plans Macroeconomic Policy Introduction Macroeconomic policies refer to policies directed at stabilising the aggregate level of economic activity or output. The fundamental rationale for government macroeconomic intervention is to stabilise fluctuations in the business cycle. Through the conduct of such ‘counter cyclical’ or ‘stabilisation’ policies the government seeks to achieve three major objectives. • Economic growth that is sustainable in delivering rising real incomes whilst minimising inflationary pressures and the current account deficit as a percentage of GDP; • Internal Balance, which is characterised by full employment and price stability; • External Balance, which involves financing import expenditure with export income, stability of the exchange rate, and minimising the levels of net foreign liabilities and net foreign debt as a percentage of GDP. Other objectives include ensuing that the benefits of economic growth are enjoyed by all groups of the population through an equitable distribution of income, as well as ensuring that economic growth and development is ecologically sustainable such that it meets the needs of present generations without compromising the ability of future generations to meet their own needs. Macroeconomic policies operate on the demand side of the economy since changes in the settings or stances of fiscal and monetary policies will impact on the growth of aggregate demand. • If AD exceeds AS at the full employment...

...MACROECONOMICS UNISA SP2 2012 ASSIGNMENT 2 Q1. The consumption schedule shows the various amounts households plan or intend to consume (spend) at various possible levels of their disposable income (Jackson, et al., 2011). Disposable income that isn’t spent is called ‘savings’. Consumer confidence measures the degree of optimism that consumers feel about the state of the economy and their personal finances, to forecast future spending. Figure 1.1 Source: Jackson et al, 2011 When people expect their real income to increase, they spend more of their current income (saving less), increasing current consumption and the aggregate demand curve shifts rightwards. Conversely, when people expect their real income to decrease, they spend less of their current income (saving more), decreasing current consumption and the aggregate demand curve shifts to the left.

Guyana one the poorest and tiniest country in South America has made great strides in becoming independent.

Also, Guyana is considered a part of the Anglophone Caribbean; the independent English-speaking Caribbean region (about.com, 2012). Today Guyana is deemed as a republic with an executive branch of government filled by the president and the prime minister. Some of the concerns with the economy are that The Guyanese economy displayed modest economic progression in recent years and is centered mainly on agriculture and extractive industries (state.gov, 2011).

...Macroeconomic Picture of Agriculture sector in Indian Economy Theodore Schultz began his acceptance speech for the 1979 Nobel Prize in Economics observing: “Most of the people in the world are poor, so if we knew the economics of being poor we would know much of the economics that really matters. Most of the world's poor people earn their living from agriculture, so if we knew the economics of agriculture we would know much of the economics of being poor” (Shultz, 1979). Existing empirical evidence on the impact of macroeconomic variables on agriculture remains mixed and inconclusive. This paper re-examines the dynamic relationship between monetary policy variables and agricultural prices using alternative vector auto regression (VAR) type model specifications. Directed acyclic graph theory is proposed as an alternative modeling approach to supplement existing modeling methods. Similar to results in other studies, this study Â’s findings show that over the time period analyzed (1975–2000), changes to money supply as a monetary policy tool had little or no impact on agricultural prices. The primary macroeconomic policy instrument that affects agricultural prices is the exchange rate, which is shown to be directly linked to interest rate, a source of monetary policy shock. The Transmission of Exchange Rate Changes to Agricultural Prices (July 2009) provides empirical evidence that price and exchange rate transmission for agricultural products is low in most developing...

...Macroeconomics in Terms of GDP and Economic Events There is deference in terms used to describe the gross domestic product and different aspects of the GDP. The GDP is useful to decide how the economy is growing or declining on an annual basis. Changes in the GDP cause other changes in interest rate, Nominal GDP, unemployment rate, and inflation. Understanding what these terms are is the first step to understanding the economy and current events. Gross Domestic Product (GPD) is the total monetary value of both products and services produced in a country of a specific period and calculated annually. The GDP comprises of private and public consumption, government outlays, exports and exempting imports within a defined area or territory, and investments. Real GDP, referred to as inflation, is an adjusted measure reflecting the value of products and services in a given year. The Real GDP accounts for changes in price level, giving a more accurate figure for the year. Nominal GDP is gross domestic product that is adjusted for changes in price levels or inflation. The unemployment rate is the percentage of total labor force not employed but is willing to work and seeking employment. Inflation rate is the rate general level of prices of goods and services rise reducing in long-term purchasing power.

Unemployment is at a steady high, there’s a staggering inflation and the recession continues to effect people after so many years. The 2008 Financial Crisis had a more detrimental impact on advanced economies like the US than on developing economies like China and India, leading to wider projected disparities between the future GDP growth rates of the advanced and developing economies. According to Trading Economics, “The Gross Domestic Product (GDP) in the United States expanded 2.70 percent in the third quarter of 2012 over the previous quarter. Historically, from 1947 until 2012, the United States GDP Growth Rate averaged 3.2 Percent reaching an all-time high of 17.2 Percent in March of 1950 and a record low of -10.4 Percent in March of 1958.Unemployment Rate in the United States decreased to 7.70 percent in November of 2012 from 7.90 percent in October of 2012”. The recovery of the US job market has not taken off as many had expected and recently the economy added a disappointing number of available jobs. With the lack of jobs, unemployment rates continue to be an issue. The economy has lost more jobs...
