Six steps to writing a successful narrative Essay Example for Free

Six steps to writing a successful narrative Essay A narrative should be able to tell a story, whether it relates to fiction or non-fiction ideas. In writing any form of literary narrative, several steps should be followed to arrive at a coherent and consistent whole. The first step involves the identification of an appropriate topic, that which stirs the best interest of the target reader. It is in this first step that the attention of the reader will be established. Secondly, the major details that will be interwoven into the storyline must be gathered, included in which are the characters, setting, conflict and the events that make up the plot. Without this, the narrative may be exposed into several risks like, disorganized thoughts and missing details. It may further contribute confusion to readers since this part lays all the foundations of pre-creating a story. Subsequently, the results of the gathered information must undergo the assessment of an instructor or any learned narrative writer. This serves as a guide whether supplementary accounts must be added or eliminated. The fourth step, which necessarily deals with the construct of an outline, takes account of the introduction, the main events and the conclusion. Gathered details are coherently fabricated according to the writer’s choice of style, whether for a tone of whodunit, essay, poems etc. It is best to evaluate the details of this next step through sensory details. Moreover, transitions and dialogues must be properly observed to help guide the readers on the events the writer tries to show. For corrections to the written work, editing and proofreading courtesy of an instructor constitute the fifth step. Finally, the corrected story can now be shared among others to live up the ideas incorporated in it.

Child labour in the global economy

Child labour in the global economy This report proposes to examine the key effects, elements and issues surrounding child labour in relation to the global economy. Through their thorough and convincing research, the authors, Eric .V.Edmonds and Nina Pavcnik (2005) estimate the number of economically active children between the ages of 5-14 years and claim that parental poverty is its main cause. However, they are hesitant to endorse the widely held belief that international policies are the solution to this global crisis; rather they suggest more domestic measures to limit it, such as affordable education and more job stimulation. They also argue that contrary to popular perception most working children engage in domestic/market work rather than in manufacturing establishments. Introduction The term Child Labour is a widespread phenomenon often equated to child abuse. In Erics footnote on What is Child Labour? He states the International Labour Organisations (ILO) definition of child labour which is defines an economically active child as a child labourer if she is under 12 and economically active for one or more hours per week, 12-14 and working more than 14hours per week or one or more hours per week in activities that are hazardous by nature or circumstance and if she is 15-17 and works in unconditional work forms of child labour (trafficked children, children in bondage or forced labour, armed conflict, prostitution, pornography, illicit activities)(ILO 2002, cited in Edmonds and Pavcnik 2005; pp.200). Edmonds asserts however that these forms of child labour are rare. He insists stating that children engage in activities which could either be harmful or beneficial depending on the type of activity and also the impact on the child should depend on what the child would be doing if not working (the childs alternative foregone). Household Survey evidence by the ILOs Statistical information and monitoring program on child labour (SIMPOC) also defines child labour as A child is defined as economically active if he or she works for wages (cash or in-kind); works in the family farm in the production and processing of primary products; works in family enterprises that are making primary products for the market, barter or own consumption; or is unemployed and looking for these types of work (ILO 2002,cited in Edmonds and Pavcnik 2005; pp.201). This is a more practical definition taking into account that most children work at home for their families; either on the farm or domestically. The rare hazardous forms of labour stated in the ILOs definition are difficult to make out in household surveys which the SIMPOC are based on thus specialized surveys are conducted by the ILO and other concerned organizations. As a result of these surveys, the ILOs SIMPOC (2002) estimates 8.4 million children engage in unconditional work forms of child labour and of these, 68 percent are in bonded or forced labour (forms of slavery). According to Edmond and Pavncik most child labourers are employed by their parents to work on the farm or domestically which goes against the widely held view that children work mainly in manufacturing establishments and other forms of employment. They argue that children also face risks in the simplest forms of labour as they get older, for example agriculture, due to exposure to toxic chemicals, harsh weather conditions, animals/parasites. Ashagrie (1997) agrees with this point stating that the self reported injury rate from child labour surveys of chi ldren working in agriculture is actually higher at 2 percent than the 9 percent level reported in manufacturing. (Ashagrie 1997 cited in Edmonds and Pavcnik 2005; pp.208) Edmonds and Pavnciks article posits an open research question as to whether the reasons children engage in these hazardous working conditions differs from the driving force of children working on their family businesses or domestic work. Literature review. Child labour in the global economy is estimated at 211million, ILO (2002), which accounts for 18 % of children, aged 5-14 worldwide. Of these, 60 % are in Asia and 23 % in sub Saharan Africa. Although Asia has a greater percentage of child labours Africa has a higher participation rate estimated at 30%. SIMPOC also estimates that 4 % of children work in transition economies (i.e. countries undergoing economic liberalization) and 2% in developed countries. The United Nations childrens educational fund (UNICEF) conducted three surveys in thirty-six less developed countries in 2000 and 2001 providing information on the participation rates in both domestic and market work for 124 million children. The first survey helps buttress Edmond and Pavcniks point on child workers engaging mainly in domestic/ market work rather than manufacturing establishments. Participation rates in various activities for 124million children 5-14 from 36 countries in 2000. All children 5-14 Age 5-9 10-14 Gender Male Female Location Urban Rural Market work (MAR) 25.0 15.3 35.2 26.6 23.3 18.9 30.5 Paid 2.4 1.0 4.0 2.8 2.0 2.2 2.5 unpaid 5.8 4.4 7.3 5.6 5.9 4.0 7.3 family 20.8 12.4 29.7 22.4 19.1 14.8 26.2 Domestic work (DOM) 64.6 50.8 79.2 59.3 69.9 60.7 67.4 Any work (MAR + DOM) 68.4 53.5 84.3 64.8 72.1 64.1 71.7 20 or more hours per week 20.7 10.3 31.8 19.4 22.1 14.1 26.4 40 or more hours per week 6.4 2.7 10.3 6.1 6.7 3.6 8.8 UNICEF End of Decade Assessment microdata, (2000). See Edmonds and Pavcnik (2005, JEP). From the table above it is evident that less than 3% of children work outside the household for pay and this is mainly the case in rural settlements rather than urban where manufacturing activities are dominant. Approximately 6% participate in unpaid work. Edmonds and Pavcnik interpret these unpaid children as those children who help their neighbours in the farm or business or could also be children receiving in-kind payments (food) as well as children who are indebted to their employees by their parents. However in contrast to this, 20.8% of children work in family businesses and of this figure, 26.2% are in rural areas and 14.8% in urban. The authors further research shows that there is an agreement with this UNICEF survey from other available data from countries like Nepal, South Africa, Vietnam, India as well as Bangladesh where child labour in its garment industry also had a figure of 1.2% unpaid children age 5-14 as cited in a 2002 child labour survey. According to the table ap proximately 65% of children work domestically and 68% work in both market and domestic work. There is a high participation rate pattern by older female children age 10-14 in rural areas. The table also shows that they tend to work longer hours than males. This is probably due to cultural domestic values. Agriculture takes the largest part of the employment sector in countries (e.g. Kenya 77% In 1998, Guatemala 63 %in 2000, Ethiopia 89% in 2001 etc) followed closely by domestic work and then manufacturing which is only a percentage of economically active children. Figures from the Food and Agricultural Organisation (FAO) 2004 (FOA 2004 cited in Edmonds and Pavcnik 2005)match with this indicating that most adults work in agriculture and since most children work with their parents they also work in agriculture. There is a trade off between work and school for child labourers. Most working children attend school and the UNICEF estimates in its second survey the total hours of work in relation to different types of work as well as school attendance. The data shows that on average, children spend 26 hours on market work weekly. Children that work for their families and are unpaid spend 27hours weekly. Paid employment takes up more hours in a week and by older children. Children that take part in domestic work spend 16 hours per week .Edmonds and Pavcnik further stated that these figures should not imply that domestic work is insignificant because on average, majority of the hours spent on market work is indeed domestic work. However children that attend school spend less hours working than those who do not attend school. The third survey below by the UNICEF reports the school attendance of children aged 5-14. From the table we observe that approximately 70% of children in that age range attend school and this attendance is mainly in favour of older male boys, in urban areas. School attendance conditional on work status accounts for 74%. There is a 14% likelihood that children who do not work do not attend school but this is reflected mainly in younger children. Less than 5 % of the 30% of children that do not attend school work in market work only and we see that domestic work is more popular in this case as 32% of the 30% participate in it alone. Thus Edmonds states that in ignoring this figure of domestic work researchers would lose out on one of the segments of children not attending school. A large fraction of children, 42%, well known as idle attend neither school nor work Work and schooling status for 124million children 5-14 from 36 countries in 2000 All children 5-14 Age 5-9 10-14 Gender Male female Location Urban rural Attend school 69.5 58.9 80.8 70.768.3 75.1 63.9 Attendance rates conditional Any work Not work 73.9 60.0 64.1 80.6 52.9 82.2 75.7 72.3 61.6 57.8 80.1 68.3 64.9 52.8 Conditional on nonattendance Domestic only Market only 32.0 4.5 30.8 34.9 2.8 8.3 27.1 36.6 6.3 2.7 31.8 32.0 4.9 4.3 Both market and domestic Not work 22.0 41.5 13.1 42.2 53.3 14.6 20.3 23.5 46.2 37.1 12.8 26.6 50.6 37.1 UNICEF Multiple Indicator Cluster Survey End of Decade Assessment microdata.(2002) Child labourers face consequences on schooling attainment because time spent working gives less time for extracurricular activities and might weaken their school performance. Orazem and Gunnarsson (2004) find that third and fourth graders who attend school but never work in market or domestic work perform 28 % better on mathematics tests and 19% better on language tests than children who attend school and work. Empirical evidence of this is given in an example by Beegle, Dehejia and Gatti (2004) wherein after five years of working and schooling they examined the status of young adults in Vietnam. They observed that a one standard deviation increase in the hours worked by children attending school is equated to a 35% decrease in educational attainment. Edmonds and Pavcnik however are of the school of thought that this negative correlation between working and grade advancement might reflect that low performing students engage in work rather than that work generates low-performing stude nts. Parents send their children to work not by choice but as a result of economic necessity thus Child labour is caused fundamentally by poverty and as far back as data show, there have been several policies proposed with the aim of fighting against child labour worldwide. Have these legislative acts helped solve the problem of child labour? To answer this question Edmonds and Pavncik give two examples, firstly the US Congress enacted laws prohibiting the importation of goods made by children and as a result of these sanctions, Bangladesh was said to have released over 10,000 paid child workers below the age of 14 from its garment industry in the mid 1900s. Evidently this is not drastic as the figures are a tenth of the percentage of child workers in Bangladesh. Furthermore Moehling (1999) finds little evidence that minimum wage laws in manufacturing sectors put into practice between the years 1880 and 1910 contributed to the decline in child labour during this period. In addition, the a uthors state that more recent studies show that the US House of Representatives have discussed the Child labour elimination act which would enforce punitive measures, alter financial support, and order US oppositions from multilateral development banks to 62 developing countries affected by child labour. Edmonds and Pavcnik argue that although these policies might help reduce child labour, they are not guaranteed to be successful in less developed nations where they are targeted at for these reasons enumerated in their article: Lack of available resources to implement policies (i.e. bans) mainly in cases where the children engage in market work for their parents wherein the end product contributes to the family income. Child labour policies are seen as a case of multiple equilibrium, Basu and Van (1998), whereby children that work at low wages are at one equilibrium and increased adult wages when children do not work are at another therefore defeating the purpose of the ban. Moreover according to Basus example (2003), if firms are fined for child labour, the cost of the fine increases the demand for cheap child labour as opposed to high earning adult workers in order to make more profit to offset the fine which in turn makes child labour necessary. Children that are prohibited from working legitimately might move into more hazardous forms of child labour or non exporting sectors of the economy such as prostitution however there is no scientific evidence of this. Since Poverty is the main cause of child labor it would be logical to combat child labor by A) Improving the standard of living of families i.e. increasing adult income which in turn does the following Diminishes the marginal utility of income which decreases the value of marginal contribution because as more income comes into the family form parents it eliminates the satisfaction derived from the income contribution of the child. Brings about the purchase of alternatives used in place of child labour (e.g. washing machines) Increases a childs productive level in schooling (human capital) because the family is now able to afford necessary materials (e.g. textbooks) B) Encouraging credit markets to give loans to poor households is another suggestive method because child labor has been said to be a result of credit market imperfections. Baland and Robinson 2000; Ranjan, 2001 agree with this stating Several theoretical studies emphasize that if credit markets allowed households to borrow against future earnings child labor could be much reduced C) Providing affordable education because parents would be willing to contribute to improve their childrens long run chances yet, are however left with no choice but to send their children to work due to the perceived returns to schooling. Policies have been adopted to reduce chid labour through educational subsidies. An example of such is the Progresa program in Mexico which is predominately used in many countries worldwide. It gives parents an incentive to keep their child in school. Parents are paid if the school certifies that the child has been attending school regularly. Thus it is a demand approach aimed at reducing the cost of schooling, which varies with age of the child, and increasing family income. Conclusively relying on laws and their enforcement as discussed previously, is a necessary but unsatisfactory solution to child labour. Overall, economic development interventions relevant to the underlying cause are more effective policy tools to reduce the incidence of child labour.

I Corinthians 6:12-13 :: Christianity Christian Biblical Essays

I Corinthians 6:12-13 "Everything is permissible for me" — but not everything is beneficial. "Everything is permissible for me" — but I will not be mastered by anything. "Food for the stomach and the stomach for the food" — but God will destroy them both. The body is not meant for sexual immorality, but for the Lord, and the Lord for the body (NIV). The broadest of freedom is being able to do what you want, when you want to do it, and wherever and however you want to do it. Freedom is being able to control our lives to do what pleases us, or what we think is going to give us the highest amount of pleasure. It is the freedom to choose anything, without any restrictions, and it is what every single person wants. But there is a more narrow form of freedom, the freedom to choose, not just anything, but the right thing. I believe this was the case in the church in Corinth concerning this passage. The church in Corinth was a young church that Paul established when he was there and was having problems with their new-found freedom. The Corinthian Christians were not sure which laws, if any, applied to them because of the freedom from the law they have in Jesus. The letter was written to the church to advise them on how to handle the problems. Some problems were spiritual arrogance, wrong-doings against other believers, sexual immorality, and misunderstanding on Christian beliefs. In these two verses, 1 Corinthians 6:12-13, Paul is addressing the immorality of their sexual practices. The city of Corinth is a sex-crazed society, where sex outside marriage is lawful, but not in God's law. Mathew Henry comments, "the maxim of lawful liberty to countenance the sin of fornication, though it might be allowed by the Corinthian laws, was a trespass upon the law of nature, and utterly unbecoming a Christian" (page #). Their freedom is under a new standard of law. Our bodies are the only thing we have 100 per cent control of when it comes to what we do with our bodies, not even God has control of it. In this passage Paul is saying that I can choose to do whatever I want, regardless, but not everything I choose is good for me. I have control over all my choices, but I won't allow my choices to control me. Paul makes an analogy of the food and its relationship to the

The Origin Of Language Essay -- essays research papers fc

There has been considerable historical discourse over the nature of language. Most contend that thought and language are two interrelated criteria. Just how these criteria relate to the controversy over whether animals have language capabilities and even more specifically to the Sapir-Whorf human language thought debate, however, is not always clear. From a human context we know that language is a skill which allows us to communicate our thoughts to others and in so doing to attain desired "biological, cognitive, and social/behavioral feedback" (McDonnell, 1977). The question as to whether language is a skill that human beings are born with or whether it is a skill that is acquired is a complex one and not one in which all researchers are in agreement. Neither are researchers in agreement about whether animals have the capability of language. To resolve these controversies we must look to both human and animal research. The linguistic relativity theory known as the Sapir-Whorf hypothesis was developed by Benjamin Lee Whorf (a linguist and anthropologist) and Edward Sapir. The theory argues that language is a finite array of lexical and grammatical categories that group experiences into usable classes which vary across cultures but influence thought. The theory maintains that a concept cannot be understood without an appropriate word for that concept. To explore this theory and the animal language controversy we must first accept that both animals and humans have the capacity for language. The next task then would be to determine whether that capacity is innate or acquired. A characteristic which is innate is an instinctual behavior and most often one which one was born with. An innate or instinctual behavior is often associated with an organism's genetic propensity to behave or react in a certain way. Innate language ability or our genetic makeup, under the Sapir-Whorf hypothesis, would serve to limit the conceptual ability of an individual for without words concepts could not be understood according to this hypothesis. There are numerous points which can serve to discredit this hypothesis. The interaction between genetic makeup and behavior or reaction is an interesting one. Some researchers contend that basic linguistic organization, or grammar, is a one, which is built into the human brain (McConnell, 1977). These researcher believe that humans... ... is, inarguably, a tremendously important part of linguistic development and refinement. Obviously it is social interaction which determines the particulars of our language. It could be contended therefore that because animals have not been presented with the appropriate stimulus which would require the refinement of their language, they have not refined language skills to the degree which is evidenced in humans. This does not mean that animals are incapable of language, or that they lack an understanding of concepts due to their lack of words for those concepts, just that they presently lack the degree of refinement which is observable in human language.

Cassegrain Antenna : Report

R. V. COLLEGE OF ENGINEERING, BANGALORE DEPARTMENT OF TELECOMMUNICATION ENGINEERING Radiating System :Report on Cassegrain Antenna Under the guidance of: Dr K. ShreeLakshmi Submitted by: Santosh H. R [1RV09TE047] Kishore B [1RV09TE025] Mayank [1RV09TE030] Kirthi K [1RV09TE024]Table of Contents : ContentsPage no. 1)Introduction to Cassegrain antenna. 01 2)Geometry of Cassegrain antenna. 02-03 3)Advantages and Drawback of Cassegrain antenna. 04 4)Applications of Cassegrain antenna . 05-06 5)Conclusion. 07 6)References. 08 Introduction: The two-reflector system invented by Nicholas Cassegrain has been used extensively in optical telescopes, primarily to achieve a long effective focal length with a convenient physical configuration. During the late 1950s, widespread interest developed in the use of this type of system for microwave frequencies.Axially symmetrical dual-reflector antennas (Cassegrain) classical or shaped) are of interest in radio astronomy and in Earth-station antenna t echnology. The design of such systems is often restricted by some mechanical constraints, the type of feed horn used, and the budget of the project (closely related to the size of the reflectors). Taking into account all of the above, various sets of input parameters, representing various solutions, are considered. From these input parameters, the overall geometry of the antenna is derived in closed form. †¢What is a Cassegrain antenna?In telecommunication and radar use, a Cassegrain antenna is an antenna in which the feed radiator is mounted at or near the surface of a concave main reflector and is aimed at a convex subreflector. Both reflectors have a common focal point. Energy from the feed unit (a feed horn mostly) illuminates the secondary reflector, which reflects it back to the main reflector, which then forms the desired forward beam. Cassegrain antenna is a double reflector system which has many interesting features such as high efficiency, low noise temperature perfor mance, and easy accessibility to electronic equipment. 1 Photo: Cassegrain antenna 02 Geometry: The classical Cassegrain geometry, shown in the below fig, employs a parabolic contour for the main dish and a hyperbolic contour for the sub dish. One of the two foci of the hyperbola is the real focal point of the system, and is located at the center of the feed; the other is a virtual feed point which is the real focal point of the system, and is located at the center of the feed; the other is a virtual focal point which is located at the focus of the parabola.As a result, all parts reflected from both surfaces, travel equal distances to a plane in front of the antenna. Fig: Geometry of Cassegrain Antenna Geometrical parameters for selected Cassegrain antenna Type Cassegrain Focal length fm=1. 5meter Aperture size X Dx=2meter Aperture size Y Dy=2meter Magnification M=5 Interfocal length fs=1. m 03 Advantages: 1. Less prone to back scatter than simple parabolic antenna. 2. Much more co mpact for a given f/d ratio. 3. Reduction in spill over and minor lobe radiation. 4. Ability to place the field in a convenient position. 5. Capability of the scanning and broadening of the beam by moving one of the reflector surfaces. Drawback of Cassegrain antenna: Antenna,which whether transmits or receives correct signal or not is our main care and our direction,is an important part in any communication systems.Because of the characteristics of laser different from radio,the antenna system of point-to-point laser communication system must be designed strictly. Newton system,Green system and Cassegrain system are accepted commonly in optical antenna systems as field lens which include refraction system,inflection system and refraction-and-inflection system. In this paper,Cassegrain antenna is discussed. However,the potential problem of sheltering ratio in Cassegrain system leads to a loss of effective power of the optical system so called vignette phenomena.The other is related t o optical aberration,because Cassegrain antenna sacrifices sight field for perfect image. 04 Applications: 1)ASTRO-G/VSOP-2 off-set Cassegrain telescope The VSOP-2 satellite has an offset Cassegrain antenna. The antenna consists of a 9-m mesh-surface paraboloid main reflector, a solid hyperboloid sub-reflector, and three feed horns. The satellite has 8. 0, 22, 43 GHz band receivers. The main reflector is consisting Of 7 hexagonal modules. The radial rib structure is newly adopted for the modules to shape a surface with accuracy of 0. mm-rms. And three band feed horns are juxtaposed at the Cassegrain focus. 05 2)Cassegrain Antenna With Hybrid Beam Steering Scheme for Mobile Satellite Communications. A hybrid antenna (HA) with a modified beam steering method is proposed. This antenna has a Cassegrain structure composed of two reflectors and a feeder. The parabolic-shaped main reflector is designed for high gain, while the subreflector is rotational and flat. The feeder is a phased arr ay with arbitrary shaped aperture and 20 element antennas.The HA is capable of two-dimensional beam steering by means of two operations: rotation of the subreflector and phase control of the feed array. The subreflector is small in size and weight, so it can provide rapid beam scanning. Designed to be loaded in vehicles, the HA and can communicate with satellites on the move by tracking the beam control of the feed array. A prototype of the HA is fabricated with aluminum using a machining center operated by computerized numerical control. The prototype is operated at Ka-band for TX and K-band for RX with gains of 47 dBi and 44. dBi, respectively, at a steering angle of 0 . The two-dimensional beam steering within +/- 2 degrees with respect to 45 elevation is realized by the subreflector and feed array. All radiation patterns in the beam steering zone meet ITU-R s. 465-5 regulations. 06 Conclusion: This report contains the information of what is a Cassegrain Antenna and its design pa rameters. We learnt of how the parabolic reflector and hyperbolic subreflectors are designed based on the geometry of the Cassegrain Antennas. We have shown some of the advantages of this antenna over other antennas and the principle drawback of this antenna.We have shown two major applications of this Antenna which deals with the design of Cassegrain telescope and a beam steering scheme for mobile satellite telecommunications. 07 References: 1.

Renminbi Case

662, Case 3 1. Do you think the Renminbi is overvalued against the US Dollar? 2. Why does the Chinese government want to keep its currency at an artificially low level against the US Dollar? What is the risk for China? For the US? 3. What would be the consequences of a 20% revaluation (increase in the value of the Renminbi) for China, western countries, Japan, and developing countries? How would it impact workers, exporters, and importers in China? Various studies have suggested that the RMB is undervalued, with recent estimates ranging from 15-50 percent. The greatest beneficiary from a gradual RMB revaluation, accompanied by measures to stimulate demand, will be China itself. Its growth is likely to be more balanced and resilient, and that will have a positive spillover on the rest of the world, including by reducing currency and trade tensions. RMB revaluation causes a loss to consumers outside China since they will confront higher prices of goods imported from China. These losses have to be offset against those of producers who will gain competitiveness. Moreover, China’s trading partners are more likely to gain from RMB revaluation if it comes with measures that accelerate China’s domestic demand relative to its GDP. Indeed, without those measures, the effect of RMB revaluation on China’s current account surplus is likely to be marginal or even to widen it. In the very long run, a revaluation of the RMB could help commodity-exporters to diversify into basic manufacturers. However, over the next few years, RMB revaluation is unlikely to affect these countries’ exports significantly because the prices of their commodity exports are determined in global markets (and denominated in dollars). However, the dollar prices of China’s exports to those countries are likely to rise, reflecting small profit margins in those sectors and the fact that China, as the biggest exporter of those goods, is the price-setter. Some middle-income manufacturing exporters running a trade surplus with China will benefit, too. Other middle-income exporters that import a lot from China could be net losers from the hike in China’s export prices in the short term, but gain as their export volumes expand at China’s expense. Low-income commodity exporters will generally be net losers from RMB revaluation alone and will only benefit if China’s growth accelerates because of accompanying measures taken by the Chinese authorities. Some high-income countries, such as Germany and Japan, which have an initial small trade deficit with China, may lose or gain a little from RMB revaluation alone. However, countries such as Italy and the United States—whose initial trade deficits with China are large and whose exports are not competitive with China’s—will very likely lose, and their lower-income consumers will suffer most as the price of Chinese goods rises. This conclusion does not imply a judgment that a large bilateral trade deficit in Italy and the United States with China is good or bad. It only implies that RMB revaluation is not the way to fix the deficit problem. Instead, increasing national savings rates in Italy and the United States, and increasing consumption in China would be more effective. Given China’s high dependence on price-sensitive exports, a large one-time RMB revaluation may carry unacceptable risks to its growth and stability. In the event of a sharp slowdown in China, those countries that are likely to lose from RMB revaluation anyway, starting with the United States.
