Monetary Policy Essay Example for Free

Monetary Policy Essay Introduction Monetary policy is the process by which the monetary authority of a country controls the supply of money, usually targeting a rate of the interest for the purpose of promoting economic grown and stability. ( Wikipedia ) In the short run, monetary policy affects the lever of output as its compositions can also affects the lever of output. An increase in money leads to a decrease in interest rates and a depreciation of the currency. Both of them can lead to an increase in the demand for goods and an increase in output. (Blanchard, 2009) There are two different ways of monetary policy, an increase in money supply is called monetary expansion and a decrease in the money supply is called monetary contraction. This essay express how monetary policy can rise the lever of aggregate demand in the short run based on money supply, interest rate, income and bond price. The relation between the nominal income and demand As we know thar the relation between the demand for money, nominal income and the interest rate is: Md =$Y L(i) (-) that means the interest rate has a negative effect on money, an decrease in the interest rate increases the demand for money. In other words, the demand for money increases in proportion to nominal income, and the demand for money depends negatively on the interest rate. According to the Figure1, the initial equilibrium is at point A. As increase in nominal income from $Y to $Y, increasing the level of transactions, which increases the demand for money at any interest rate. The money demand curve shifts from left to the right(Md to Md) the new equilibrium moves from A up to A, and the equilibrium interest rate increases from i to i. [pic] Figure 1: The effects of an Increase in Nominal Income on the Interest Rate. Source: Adapted form Blanchard 2009 Thus, an increase in nominal income can raise the level of demand for money in the short run. The relation between the money supply and demand When the money supply changes, the interest rate will changes in proportion to the supply. The relation between them shows in figure 2. [pic] Figure 2: The effects of an increase in the Money Supply on the Interest Rate Source: Adapted form Blanchard 2009 The initial equilibrium is at point A, the interest rate is i. An increase in the money supply, from Md=M to Ms=M, leads to a shift of the money supply curve to the right. The equilibrium moves moves from A down to A, the interest rate decreases from i to i. It indicate that an increase in the supply of money by the central bank leads decrease in the interest rate, thus can raise the level of demand for money in short run. At the same time, an increase of the demand for money needs more output in order to satisfy the high demand for money, then people will earn more money, in the end the level of aggregate demand would also increase. The relation between monetary policy and interest rate When analysis the IS-LM curve, a same answer can be got. For the IS curve, as the money supply does not directly affect either the supply of or the demand for goods, a change of M does not appear in the IS relation to shift it. For the LM curve, however, as we know that an increase in the money supply shifts the LM curve down, from LM to LM. In other words, an increase in money leads to a decrease in the interest rate. Take all factors into consideration, the economy moves along the IS curve, and the equilibrium moves from A to A, output increases from Y to Y, and the interest rate decreases from i to i. [pic] Figure 3: The effects of a Monetary Expansion Source: Adapted form Blanchard 2009 Therefore, increasing money supply, decreasing interest rate and increasing income can raise the level of aggregate demand(Blanchard 2009) Turn to consider about the effects of an open market operation. The price of the bond today is equal to the final payment divided by 1 plus the interest rate(Blanchard 2009). $PB=$F/1+i That means the higher the price of the bond, the lower the interest rate. So the central bank increases the money supply in open market operations by buying bonds lead to an increase in the price of bonds, a decrease in the interest rate, an increase in the level of aggregate demand in the short term. The relevance for the UK since 2009 For example, according to the figure 4, the level of GDP in UK has experienced a plunge since 2007 because of the crisis. At the same time, we can see from the figure5, the bank rate gradually increased since 2007, more and more companies do not willing to invest new projects, that leads to a lower output. However, since 2009 the level of GDP consistent rise and will continue this trend in the following years. The main reason is bank rate experienced a plummet, from 6% in 2007 to 0.8%.

Proper use of Pesticides :: Chemistry Chemical Pesticide Essays

Proper use of Pesticides Storage of chemicals Store pesticides in a locked and posted facility where children or other untrained people cannot get to them. Read the labels on pesticide containers for correct storage procedures. Select a storage site high enough that damage from flooding will be unlikely and downwind and downhill from sensitive areas such as houses, play areas and ponds. Pesticide storage facilities should also be located away from homes and livestock facilities to avoid or minimize contamination in case of fire.Pesticide and expended pesticide containers are best stored in a separate building, room, or enclosure, depending on the size of the pesticide inventory. The storage area should be on the first floor to minimize contamination from a possible leaky container, and the storage area must keep the pesticides dry, cool and out of direct sunlight. The latter requirements are necessary because some pesticides are rendered useless if they become too hot or damp, if they freeze, or if they are exposed to ultrav iolet radiation from the sun.Sacks, cartons and fiberboard boxes containing pesticides should be stored on wooden pallets or on shelves off the floor. Securely lock all possible entrances to the storage area. Hang or mount weatherproof signs stating "Danger — Pesticides, Keep Out!!" or similar warnings over every entrance to the facility. An exhaust fan for ventilation should be used in storage rooms to reduce the temperature and high concentration of toxic fumes.An adequate supply of water and detergent or soap is essential in the storage area. We recommend routine use of these cleaning agents by people who work with pesticides or pesticide-related materials or equipment. Also, water is a quick first aid in a poisoning emergency. Materials such as activated charcoal, vermiculite, absorbent clay, pet litter, ground corncobs or sawdust need to be readily available at the storage site to soak up spills and leaks. Hydrated lime and sodium hypochlorite (chlorinated household blea ch) can be used to neutralize pesticides in an emergency. A shovel, dust pan, broom, and proper type of fire extinguisher are other essential items.Do not store pesticides near food for human consumption, animal feed, fertilizer, seed, veterinary supplies, or other stored products. To prevent contamination or to avoid accidentally using the wrong pesticide, store different pesticides in separate locations within the storage area.Store pesticides only in the original container, with the label plainly visible. Never store pesticides in anything used as a food or drink container, even for a short time.

Peace in Mindanao

The peace process in Mindanao still needs a lot of work. The path to peace on the Bangsamoro sector. The establishment of compromising and reaching of the meeting of minds has been conducted. What I want to see is how this will all played out. It is one big step and a giant leaf to a very narrow treacherous process to surpass from but the president assures that it will be done or happen when our countrymen will be willing to help them in their quest for peace.The people itself will have to give justification on the stipulation and not only must the president himself will be the one to fight for peace but also the people itself that must be as well involve for this is their nation to bring about the prospering of peace in the land. We all do want peace. But there is no real peace. Then has always been conflict. What action can we take in the name of peace? Can both sides change the politics of anger and resentment into a policy of cooperation?The Filipino’s lack of discipline e ncompasses several related characteristics. We have a casual and relaxed attitude towards time and space which manifest itself into lack of precision and compulsiveness, in poor time management and in procrastination. We are impatient and unable to delay gratification or reward, resulting in the use of shortcuts, in skirting the rules (pasulot syndrome) and foolhardiness. We are guilty of ningas cogon, starting out projects with full vigor and interest which abruptly die down leaving things unfinished.Our lack of discipline often results in inefficient, wasteful work system, violation of rules leading to more serious transgression and a casual work ethic leading to carelessness and lack of follow-through. The path to peace is always a sensitive topic to obtain. In life there are no shortcuts and so we must be conscious not to show our weakness in character when we mean business. I just hope in this modernize world by while walking on the road with the right determination and enduran ce that it eventually lead to the right path and that is the path to peace.There is no need for haste because peace does not come out automatically, after all people do have safety precautions labeled on each one of us that trust does not easily be gain but you work for it. As the saying goes â€Å"hastes makes wastes†. Filipinos do have strength in characters as well. One of that is the pakikipagkapwa-tao where Filipinos are open to others and fell one with others. We regard others with dignity, respect and deal with them as fellow human beings.It is manifested in a basic sense of justice, fairness and concern for others. It is demonstrated in the ability to empathize with others, helpfulness and generosity in times of need (pakikiramaray), in the practice of bayanihan and the famous Filipino hospitality. Throughout human history, mankind has seemingly always been able to solve problems. So there is a possibility that this dilemma can be surpassing despite the obstacles that awaits it.

The History and Domestication of Cassava

Cassava (Manihot esculenta), also known as manioc, tapioca, yuca, and mandioca, is a domesticated species of tuber, a root crop originally domesticated perhaps as long ago as 8,000–10,000 years ago, in southern Brazil and eastern Bolivia along the southwestern border of the Amazon basin. Cassava is today a primary calorie source in tropical regions around the world, and the sixth most important crop plant worldwide. Fast Facts: Cassava Domestication Cassava, commonly called manioc or tapioca, is a domesticated species of tuber, and the sixth most important food crop in the world.  It was domesticated in the southwestern Amazon of Brazil and Bolivia some 8,000-10,000 years ago.  Domesticate improvements include traits which must have been added by means of clonal propagation.  Burned tubers of manioc were discovered at the classic Maya site of Ceren, dated to 600 CE.   Cassava Progenitors The progenitor of cassava (M. esculenta ssp. flabellifolia) exists today and is adapted to forest and savanna ecotones. The process of domestication improved the size and production level of its tubers, and increased the photosynthesis rate and seed functionality, by using repeated cycles of clonal propagation—wild manioc cannot be reproduced by stem cuttings. Archaeological macro-botanical evidence of cassava in the little-investigated Amazon basin has not been identified, partly because root crops do not preserve well. Identification of the Amazon as the point of origin was based on genetic studies of cultivated cassava and all various possible progenitors, and the Amazonian M. esculenta ssp. flabellifolia was determined to be the wild form of todays cassava plant. Amazon Evidence: The Teotonio Site The oldest archaeological evidence for manioc domestication is from starches and pollen grains from sites outside the Amazon.  In 2018, archaeologist Jennifer Watling and colleagues reported the presence of manioc phytoliths attached to stone tools at the southwestern Amazon Teotonio site in Brazil very near the Bolivian border. The phytoliths were found in a level of dark earth (terra preta) dated to 6,000 calendar years ago (cal BP), 3,500 years older than any terra preta anywhere else in the Amazon to date. The manioc at Teotonio was found alongside domesticated squash (Cucurbita sp), beans (Phaseolus), and guava (Psidium), indicating that the inhabitants were early horticulturalists in what is becoming recognized as an Amazonian center of domestication. Cassava Species Around the World Cassava (Manihot esculenta), root and ground for dinner.   Rodrigo Ruiz Ciancia / Moment / Getty Images Cassava starches have been identified in north-central Colombia by approximately 7,500 years ago, and in Panama at Aguadulce Shelter, about 6,900 years ago. Pollen grains from cultivated cassava have been found in archaeological sites in Belize and Mexicos Gulf coast by 5,800–4,500 bp, and in Puerto Rico between 3,300 and 2,900 years ago. Thus, scholars can safely say that the domestication in the Amazon had to happen before 7,500 years ago. There are numerous cassava and manioc species in the world today, and researchers still struggle with their differentiation, but recent research supports the notion that they are all descended from a single domestication event in the Amazon basin. Domestic manioc has larger and more roots and increased tannin content in the leaves. Traditionally, manioc is grown in the field-and-fallow cycles of slash and burn agriculture, where its flowers are pollinated by insects and its seeds dispersed by ants. Manioc and the Maya The Pompeii of North America, Joya de Ceren, was buried in a volcanic eruption in August 595 CE. Ed Nellis Members of the Maya civilization cultivated the root crop and it may have been a staple in some parts of the Maya world. Manioc pollen has been discovered in the Maya region by the late Archaic period, and most of the Maya groups studied in the 20th century were found to cultivate manioc in their fields. The excavations at Ceren, a classic period Maya village that was destroyed (and preserved) by a volcanic eruption, identified manioc plants within the kitchen gardens. Manioc planting beds were discovered some 550 feet (170 meters) away from the village. The manioc beds at Ceren date to approximately 600 CE. They consist of ridged fields, with the tubers planted on the top of the ridges and water allowed to drain and flow through the wales between the ridges (called calles). Archaeologists discovered five manioc tubers in the field which had been missed during harvesting. Stalks of manioc bushes had been cut into 3–5 foot (1–1.5 meter) lengths and buried horizontally in the beds shortly before the eruption: these represent preparation for the next crop. The eruption occurred in August of 595 CE, burying the field in nearly 10 ft (3 m) of volcanic ash. Sources Brown, Cecil H., et al. The Paleobiolinguistics of Domesticated Manioc (Manihot esculenta).
