国际金融Chapter 4 重要知识点

国际金融Chapter 4 重要知识点

Chapter 4 重要知识点The measurement of all international economic transactions between the residents of a country and foreign residents is called the balance of payments (BOP).BOP data is also important1.An indication of pressure on a country’s foreign exchange rate2. A signal of the imposition or removal of controls in various sorts of payments3. A forecast of a country’s market potential (especially in the short run)The BOP must balance.The measurement of all international transactions in and out of a country over a year is a daunting task. Mistakes, errors, and statistical discrepancies (统计误差)will occur. The primary problem is that double-entry bookkeeping is employed in theory, but not in practice. Current, financial, and capital account entries are recorded independently of one another, not together as double-entry bookkeeping would prescribe. Thus, there will be serious discrepancies between debits and credits.Net Errors and Omissions. As previously noted, because current and financial account entries are collected and recorded separately, errors or statistical discrepancies will occur. The net errors and omissions account ensure that the BOP actually balances.The balance of payments is composed of three primary subaccounts: the current account, the financial account, and the capital account. In addition, the official reserves account tracks government currency transactions, and a fifth statistical subaccount, the net errors and omissions account, is produced to preserve the balance in the BOP.The BOP is a flow statement, summarizing all the inter- national transactions that occur across the geographic boundaries of the nation over a period of time, typically a year.The current account consists of four subcategories:Goods trade. The export and import of goods are known as the goods trade. Merchandise trade is the oldest and most traditional form of international economic activity.Services trade. The export and import of services is known as the services trade.Income. This is predominantly current income associated with investments that were made in previous periods. Additionally, wages and salaries paid to nonresident workers are also included in this category.Current transfers. The financial settlements associated with the change in ownership of real resources or financial items are called current transfers.The capital and financial accounts of the balance of payments measure all international economic transactions of financial assets.The capital account is made up of transfers of financial assets and the acquisition and disposal of nonproduced/nonfinancial assets.The financial account consists of three components: direct investment, portfolio investment, and other asset investmentsOfficial Reserves Account.The Official Reserves Account is the total reserves held by official monetary authorities within a country. These reserves are normally composed of the major currencies used in international trade and financial transactionsA nation’s balance of payments interacts with nearly all of its key macroeconomic variables. Interacts means that the balance of payments affects and is affected by such key macroeconomic factors as the following: Gross domestic product (GDP)、Exchange rate、Interest rates、Inflation ratesA nation’s GDP can be represented by the following equation: GDP = C + I + G + X - MThus, a positive current account balance (surplus) contributes directly to increasing the measure of GDP, but a negative current account balance (deficit) decreases GDP. In a dynamic (cash flow) sense, an increase or decrease in GDP contributes to the current account deficit or surplus. As GDP grows, so does disposable income and capital investment. Increased disposable income leads to more consumption, a portion of which is supplied by more imports. Increased consumption eventually leads to more capital investment.A country’s BOP can have a significant impact on the level of its exchange rate and vice versa.The effect of an imbalance in the BOP of a country works somewhat differently depending on whether that country has fixed exchange rates, floating exchange rates, or a managed exchange rate system.The overall level of a country’s interest rates compared to other countries has an impact on the financial account of the balance of payments. Relatively low real interest rates should normally stimulate an outflow of capital seeking higher interest rates in other country currencies.A country’s import and export of goods and services is affected by changes in exchange rates. The transmission mechanism is in principle quite simple: changes in exchange rates change relative prices of imports and exports, and changing prices in turn result in changes in quantities demanded through the price elasticity of demand. The J-Curve Adjustment PathIn the first period, the currency contract periodThe second period of the trade balance adjustment process is termed the pass-through period.The third and final period, the quantity adjustment period, achieves the balance of trade adjustment that is expected from a domestic currency devaluation or depreciation.。

语言学Chapter4课后练习答案(20200602074319)

Chapter 4 Revision Exercises1. What is syntax?Syntax is a branch of linguistics that studies how words are combined to form sentences and the rules that govern the formation of sentences.2. What is phrase structure rule?The grammatical mechanism that regulates the arrangement of elements (i.e. specifiers, heads, and complements) that make up a phrase is called a phrase structure rule.The phrase structural rule for NP, VP, AP, and PP can be written as follows: NP→(Det) N (PP) ...VP→(Qual) V (NP) ...AP→(Deg) A (PP) ...PP→(Deg) P (NP) ...We can formulate a single general phrasal structural rule in which X stands for the head N, V, A or P.The XP rule: XP→(specifier) X (complement)3. What is category? How to determine a word’s category?Category refers to a group of linguistic items which fulfill the same or similar functions in a particular language such as a sentence, a noun phrase or a verb.To determine a word's category, three criteria are usually employed, namely meaning, inflection and distribution. The most reliable of determining a word’s category is its distribution.4. What is coordinate structure and what properties does it have?The structure formed by joining two or more elements of the same type with the help of a conjunction is called coordinate structure.It has four important properties:1)there is no limit on the number of coordinated categories that can appearprior to the conjunction.2) a category at any level a head or an entire XP can be coordinated.3)coordinated categories must be of the same type.4)the category type of the coordinate phrase is identical to the categorytype of the elements being conjoined.5. What elements does a phrase contain and what role does each element play?A phrase usually contains the following elements: head, specifier and complement. Sometimes it also contains another kind of element termed modifier.The role each element can play:Head:Head is the word around which a phrase is formed.Specifier:Specifier has both special semantic and syntactic roles. Semantically, it helps to make more precise the meaning of the head. Syntactically, it typically marks a phrase boundary.Complement:Complements are themselves phrases and provide information about entities and locations whose existence is implied by the meaning of the head.Modifier:Modifiers specify optionally expressible properties of the heads.6. What is deep structure and what is surface structure?There are two levels of syntactic structure. The first, formed by the XP rule in accordance with the head's subcategorization properties, is called deep structure (or D-structure). The second, corresponding to the final syntactic form of the sentence which results from appropriate transformations, is called surface structure (or S-structure).7. Indicate the category of each word in the following sentences.a) The old lady got off the bus carefully.Det A N V P Det N Advb) The car suddenly crashed onto the river bank.Det N Adv V P Det Nc) The blinding snowstorm might delay the opening of the schools.Det A N Aux V Det N P Det Nd) This cloth feels quite soft.Det N V Deg A8.
