Exchange rate shocks and the current account under monopolistic competition: An intertemporal optimization model

This paper examines the current-account effect of a devaluation in a Chamberlinian model where both saving and investment are based on intertemporal optimization. It shows that devaluation tends to deteriorate the current account along the time horizon, leading to a reduction of the stock of foreign assets permanently. In contrast to recent work, these real effects do not rely on short-run disequilibrium in the goods or labor market. Besides, a temporary devaluation may generate hysteresis effects on both micro- and macro-economic aspects of a small economy.     

Bilateral Trade Balances: Evidence from Malaysia*

This study examines the impacts of real exchange rates on the bilateral trade balances of Malaysia with the USA, Japan and Singapore. The results for the long‐run cointegrating vectors show that depreciation or devaluation of real exchange rates will improve bilateral trade balances. In the short run, there is some evidence of the J‐curve phenomenon. Changes in real money supply contribute greatly to changes in real exchange rates. Generally, changes in real exchange rates contribute significantly to changes in bilateral trade balances. Monetary policy can be used to influence bilateral trade balances.     

On budgetary policies, growth, and external deficits in an interdependent world

We investigate the effects of budgetary policies in a two-country model of overlapping generations and endogenous growth. In the presence of capital mobility, endogenous growth rates are equalized, but output levels do not converge. A worldwide rise in the public debt to GDP ratio or the share of government consumption reduces savings and growth. A relative rise in one country's debt to GDP ratio or its GDP share of government consumption results in a fall in external assets and its relative savings rate. In the short run, the fall in the savings rate is higher, and the country experiences higher current account deficits as a percentage of GDP.     

The elasticities approach in general equilibrium: Real shock dynamics

This paper constructs a general equilibrium model that embodies: the elasticities approach to the trade balance in the long run, but allows for inelastic short run demand; and an asset market approach to the capital account, with uncovered interest parity and consistent expectations.Two policies are examined: increased government expenditure and an increased import tariff. The effects of these policies on net exports, the exchange rate, and other variables are determined. A phase diagram demonstrates the dynamic adjustment paths of the exchange rate and the trade balance, and provides a general equilibrium explanation for overshooting and the J-curve as a result of real shocks. Extensions are made to account for policy pre-announcement, the Laursen-Metzler effect, and large-country effects.     

The Effect of Exchange Rate on Bilateral Trade Balance: New Evidence from Malaysia and Thailand

This paper attempts to identify the major economic factors that influence the bilateral trade balances of Malaysia and Thailand with the US and Japan. To this end, an unrestricted VAR model was estimated using quarterly frequency data from 1980: I to 1996: IV. The Johansen results indicate a stable long-run relation between trade and three macro variables: exchange rate, domestic income and foreign income. The main findings of this paper are: (i) the real effective exchange rate is an important variable in the trade balance equation and devaluation improves the trade balances of both economies in the long-run; (ii) the other important variables that determine trade balance include domestic and foreign incomes; (iii) the results indicate no J-curve effect and causal run from exchange rate to trade balance, (iv) the real effects of devaluation are distributed over a period of eight to nine quarters.     

Robust Monetary Framework for China

I. Introduction China has made tremendous gains in terms of economic growth in the last 15 years, by inviting foreign direct investment and increasing manufacturing production and exports. The currency unification (devaluation of the official rate and unification of the official and market rates) in 1994 also contributed to the efficiency in the monetary and foreign exchange systems. China was not severely affected by the Asian currency crisis of 1997–1998, and instead China helped the regio…     

Effects of Government Spending on the Current Account with Endogenous Time Preference

This paper extends a previous model to set up a small open economy with perfect capital mobility, and examines the effects of an unanticipated permanent rise in public spending on the optimal rates of private consumption and the current account. The novelty of the paper is consideration of the relationship between private and public consumption in the household's utility function as well as endogenous rates of time preference. It is found that the key factor determining the adjustment patterns of private consumption and the current account is the marginal utility of private consumption and of public spending, which results from endogenous recursive preferences.     

Financial crises,Asian stock indices,and current accounts: An Asian-U.S. comparative study

This paper investigates the effects of financial crises-based exchange rate, real interest rate, and personal consumption expenditure on stock market indices and balances of current account in four Asian countries/areas, and the U.S. from 1997 to 2010. Results obtained from Sims's first-order DSGE representation suggest that two policy variables – changes in the exchange rate and changes in the real interest rate lagged by one quarter – act as stabilizers for contemporaneous changes in stock indices for Thailand, Malaysia, and the U.S., but as destabilizers for Taiwan and Hong Kong. However, changes in personal consumption expenditure lagged by one quarter only play a destabilizing role in Hong Kong. For contemporaneous changes in the current account balance, all three policy variables become destabilizers for all five countries except the one-quarter lagged change in real interest rate, which acts as a stabilizer in Malaysia.     

Is devaluation expansionary or contractionary: Evidence based on vector autoregression with sign restrictions

The purpose of the paper is to examine the impact of real exchange rate changes – real devaluation or real depreciation – on outputs in 16 countries that fall within one of the three groups: Latin American countries, Asian countries, and non-G3 developed countries. For the first time in the contractionary devaluation literature, the analysis is based on a Vector Autoregression (VAR) model with sign restrictions method by Uhlig (2005) and Fry and Pagan (2011). The exchange rate shock is identified by imposing restrictions on the signs of impulse responses for a small subset of variables. The findings are as follows: (1) whether output increases after a real devaluation or not has little to do with whether the current account improves or not; (2) Latin American countries are quite homogenous in that the current account generally improves while output decreases after real devaluation; and (3) contractionary devaluation could happen in developed countries as well as in developing countries.     

The global macroeconomics of NAFTA

Previous empirical studies of NAFTA have commonly used trade models that do not allow international capital flows to adjust to changes in regional trade arrangements such as NAFTA. This paper explores the dynamic implications of NAFTA with particular focus on the short-run and longer-run adjustment of financial capital. This adjustment affects the global allocation of physical capital and therefore changes the growth prospects for a country such as Mexico. Our results suggest that Mexico and the world economy gain more from NAFTA than merely a static reallocation of production possibilities. In the short run, the adjustment of financial capital affects nominal and real exchange rates. This adjustment is far more important for the short-term allocation of trade flows than partial equilibrium adjustment of trade based only on changes in long-term price differentials.     

Why does the current account matter?

Summary Professor Lamfalussy discusses the nature and significance of the current account of the balance of payments. After a general analysis he applies his reasoning to the problems connected with the oil-price explosion and their effects on the pattern of current-account positions of various groups of countries. He arrives at two conclusions. The first is probably not very controversial: the international distribution of current-account imbalances deserves to remain in the centre of economic analysis because they are the vehicle for transferring real resources and because the position of its current account may have far-reaching consequences on each country's exchange rate, domestic price developments, income distribution and growth prospects. The second is that for these very reasons policy makers cannot disregard the structure of the balance of payments — even if they will have to realise that it is often not in their power to achieve what would seem to be an optimum structure.     

Fiscal policy, distortionary taxation, and direct crowding out under monopolistic competition

A simple macroeconomic model with monopolistic competition onthe goods market is developed which displays Keynesian features.The model is used to study the effects of a rise in public spendingon national income. The model extends the literature in twodirections. Fust, we assume that the government balances itsbudget by employing distortionary income taxation. Second, weallow for direct crowding out since public consumption entersprivate utility in a non-separable fashion. With upward dopinglabour supply, an increase in public spending depresses nationalincome, more so in the long run than in the short run.     

Dynamics of parallel and official exchange rates: The experience of hungary

This paper provides empirical evidence on the dynamics of dual markets in Hungary during the 1980–93 period using cointegration and error correction methodologies. The results suggest that the official and parallel markets were cointegrated. Short-run dynamics of these rates resulted from the overshooting and adjustment by the parallel rate to shocks, without any adjustment by the official rate. A devaluation had no significant impact on the parallel market premium in the long run. Although the premium declined in the short run, it was relatively small and sluggish. One lesson for the design of stabilization programs in other countries is that a devaluation is not a powerful policy tool to reduce the premium effectively.     

Boom and Bust Cycle of the Stock Market, and Economic Growth in a Vintage Capital Model

We construct a growth model of overlapping generations with vintage capital. There exists an equilibrium that converges to the balanced growth path through endogenous fluctuations of investment, consumption, and output in terms of the growth rate. When the technological change arrives and a rise in productivity is embodied only in newly invested capital, the economy converges to a new balanced growth path with a higher growth rate of output, but when we interpret the price of existing old capital as the stock market capitalization, the rise in productivity is accompanied by an initial decline in the stock market. Oscillatory equilibria are supported as perfect-foresight equilibria in the present framework with finitely lived agents and capital. Any oscillatory equilibrium is associated with the regime switch from an economy with both young and old capital in use into one with only old capital in use.     

日元升值与人民币升值的比较分析

人们通常会将中国的现实汇率升值与20世纪80年代中期日元施压升值联系起来。从长期来看，人民币升值是调整国内经济与国际经济秩序的关系的需要，不能简单认为是西方国家的“阴谋”。中国必须采取措施解决国际和匐内的经济失衡问题——国际收支的双顺差与过度投资而消费不足。但人民币兑美元升值不能一步到位，一方面是一次性大幅升值将沉重打击出口产业及就业，另一方面存在汇率走势逆转的可能性。运用从紧货币政策强行控制通货膨胀是难以达到理想效果的，因为引发通货膨胀的很大一部分原因在于美元的泛滥，控制增发货币的闸口并不完全在中国人氏银行掌握之中。要从根本上解决消费不足问题，对资本账户实施非对称的开放。     

Endogenous Growth and External Balance in a Small Open Economy

This paper puts forward an intertemporal model of a small open economy which allows for the simultaneous analysis of the determination of endogenous growth and external balance. The model assumes infinitely lived, overlapping generations that maximize lifetime utility, and competitive firms that maximize their net present value in the presence of adjustment costs for investment. Domestic securities are assumed perfect substitutes for foreign securities and the economy is assumed small in the sense of being a price taker in international goods and assets markets. It is shown that the endogenous growth rate is determined solely as a function of the determinants of domestic investment, such as the world real interest rate, the technology of domestic production and adjustment costs for investment and is independent of the preferences of domestic households and budgetary policies. The preferences of consumers and budgetary policies determine the savings rate. The current account and external balance are functions of the difference between the savings and the investment rates. The world real interest rate affects growth negatively but has a positive impact on external balance. The productivity of domestic capital affects growth positively but causes a deterioration in external balance. Population growth, government consumption and government debt affect the current account and external balance negatively, but do not affect the endogenous growth rate.     

Patents,foreign direct investment and economic growth in Australia, 1860–2010

We examine the long run relationship between innovation and economic development in Australia, using 150 years of data on patenting activity, and aggregate and sectoral economic indicators. Our initial results point to several important causal relationships, particularly the effects of patents on real GDP and of private capital formation on patents. We delve deeper at the sector level and find important causal relationships of patents with real foreign direct investment (FDI) since World War II. Australia's dependence on FDI for private capital formation served as an important stimulus for knowledge creation in key sectors including manufacturing, agriculture and mining.     

跨境资本流动对银行风险的影响--基于风险累积效应和风险传染效应的视角

从风险累积效应和风险传染效应两个视角揭示跨境资本流动对银行风险的影响机理,并基于2000年第一季度至2020年第四季度时间序列数据进行经验检验,结果表明:跨境资本流动、跨境资本流入、跨境资本流出均显著增加了银行风险,且三者对银行风险的影响均存在显著的风险累积效应;跨境资本流动、跨境资本流入、跨境资本流出均通过影响金融机构人民币各项贷款余额同比增速、金融机构外币各项贷款余额同比增速、金融机构本外币各项贷款余额同比增速以及境内住户中长期消费贷款同比增速等信贷渠道显著提高银行风险承担水平,实现银行风险累积,从而增加银行风险;跨境资本流动、跨境资本流入、跨境资本流出均显著提高了股票价格、房地产价格和实际汇率的波动水平,且跨境资本流动通过股票市场、房地产市场和汇率市场将波动水平传染至银行系统,增加了银行风险,股票市场、房地产市场和汇率市场更是强化了这种传染效应。     

Overshooting adjustment to tariff liberalization

The article analyzes the dynamic effects of tariff liberalization on a small open economy. The primary focus is on nonmonotonic adjustment patterns of net lending such as overshooting or opposite short-and long run effects. When capital accumulation tilts wage income toward the future in the early transition periods, present generations perceive life-cycle type savings disincentives which create a transitory shortfall in savings. In the long run, wage profiles become flat again, and the savings deficiency vanishes. The transitory savings component may give rise to overshooting or opposite short- and long-run adjustment in the total stock of savings and net foreign assets.
