中国和东盟人民币贸易结算的经济学分析

本文构建了一个三经济体的贸易模型,从贸易损失的角度分析中国和东盟地区采用人民币进行贸易结算对中国和东盟,以及对世界其他主要经济体的福利影响。分析结果表明:中国和东盟地区结成货币联盟对世界主要经济体都将产生正面效应;由于东盟地区整体技术稍低,中国和东盟结成货币联盟将使东盟贸易损失下降更多和产出增加更大,从而提升东盟地区的整体福利;中国和东盟进行人民币结算对各经济体而言,属于帕累托改进,符合激励相容原则,具备理论上的可行性;中国和东盟进行货币联盟的优势在于两大经济体之间的地缘优势和生产技术类似。     

Inflationary Financing of Government Expenditure in an Endogenous Growth Model

This paper analyses the role of inflation in economies with endogenous growth and congestion in public services. Optimal policy rules are derived for public services and investment. The other findings are as follows. Monetary policy should maximize economic growth. The more inefficient the public sector is, the higher the growth‐maximizing inflation rate is. If a currency union accepts a new member with an inefficient public sector, this will boost inflation in the union and decrease growth and welfare in all member economies of the union.     

China's Profits and Losses from Currency Intervention, 1994–2011

China's currency policy has been criticized for its apparent pursuit of mercantile advantage by artificially stimulating exports, with potential adverse effects on other economies. While China's currency policy may have positive output effects, there may be additional profits or losses. This paper computes the annual and cumulative accounting profits from currency intervention since 1994 when China began its currency intervention. It is shown that profits initially were positive but since 2007 China has lost a massive amount from the currency market.     

Deleveraging,deflation and depreciation in the euro area

During the post-crisis period, economic performance has been highly heterogenous across the euro area. While some economies rebounded quickly after the 2009 output collapse, others are undergoing a protracted further decline as part of an extensive deleveraging process. At the same time, inflation has been subdued throughout the whole of the euro area and intra-euro-area exchange rates have hardly moved. We interpret these facts through the lens of a two-country model of a currency union. We find that deleveraging in one country generates deflationary spillovers which cannot be contained by monetary policy, as it becomes constrained by the zero lower bound. As a result, the real exchange rate response becomes muted, and the output collapse—concentrated in the deleveraging economies.     

Is East Asia an optimum currency area?

This paper assesses the empirical desirability of the East Asian economies to an alternative exchange rate arrangement (a monetary union) that can potentially enhance the exchange rate stability and credibility in the region. Specifically, the symmetry in macroeconomic disturbances of the East Asian economies is examined as satisfying one of the preconditions for forming an Optimum Currency Area (OCA). We extend the existing literature by improving the methodology of assessing the symmetry shocks in evaluating the suitability of a common currency area in the East Asian economies employing the Bayesian State-Space Based approach. We consider a model of an economy in which the output is influenced by global, regional and country-specific shocks. The importance of a common regional shock would provide a case for a regional common currency. This model allows us to examine regional and country-specific cycles simultaneously with the world business cycle. The importance of the shocks decomposition is that studying a subset of countries can lead one to believe that observed co-movement is particular to that subset of countries when it in fact is common to a much larger group of countries. In addition, the understanding of the sources of international economic fluctuations is important for making policy decisions. The falling share of country specific factor and the rising role of region factor indicate that East Asia has become increasingly favorable for a monetary union. However, the share of country-specific factor that is still significant implies that it could be costly to renounce individual currencies to advance into a monetary union in East Asia.     

Financial Development and Economic Activity in Advanced and Developing Open Economies: Evidence from Panel Cointegration

This study considers the effects of financial development on output in a panel cointegration framework, focusing on the implications of trade and financial openness. Our analysis indicates that after controlling for cross‐sectional dependence, the typical relationship between finance and output does not hold in the long run. This relationship, however, is re‐established once we account for economic openness. While trade openness emerges as more important for developing countries, financial openness is more important for advanced economies. In the long run, causality runs from financial development to output in the advanced economies, while in developing economies causality is bidirectional. There is no short‐run causality between financial development and output, however.     

Optimum currency areas and the European experience

Across nations or regions, the debate on optimum exchange rate cum monetary policies is not yet resolved on three levels. First is the optimum domain of fixed exchange rates versus keeping them flexible. Second is the subordinate debate on whether one needs full monetary union (as in continental Europe) to secure an optimum currency area's internal domain; or, whether virtually fixed exchange rates — where national currencies remain in circulation — can be sufficient. Third is whether a regional grouping of economies with close trade ties (as in East Asia) gain by collectively pegging to an outside currency such as the US dollar. Using an axiomatic approach, which limits the set of cross‐country financial claims to what is feasible, I analyse how best to both share and reduce macroeconomic risks on these three levels.

Internationalisation of the Renminbi as an Investing and a Funding Currency: Analytics and Prospects

This paper develops a three‐currency model to study the determinants of the demand for assets and liabilites denominated in an international currency and to shed light on the prospects for the renminbi as a budding international currency. We show that interest rate differentials would be only one of the factors shaping the renminbi's position, while other factors, including the correlation between foreign countries' economic growth and their bilateral exchange rates against the renminbi, and the correlation between exchange rates of the renminbi with other international currencies, would also be important. A broad interpretation of these findings is that the renminbi will likely be attractive to investors from high‐income economies and fund‐raisers from emerging market economies.     

The Rise of China and Its Implications for the Global Economy: Evidence from a Global Vector Autoregressive Model

This paper studies empirically the role of China in the world economy. We examine both the way the Chinese economy reacts to exchange rate shocks and the repercussions for the world economy of an output shock emanating from China. Based on a global vector autoregressive model and a new data set that excels in country coverage and covers the most recent time period including the global financial crisis, our results are threefold: First, we show that a +1% shock to Chinese output translates to a permanent increase of 1.1% in Chinese real GDP and a 0.1% to 0.5% rise in output for most large economies. Second, to benchmark the shock to Chinese output, we examine the response to a +1% shock to US GDP. The results show that the US economy remains dominant in the world economy, as output rises in other advanced economies by 0.6 to 1%. By contrast, China seems to be little affected by the US shock. Finally, we are the first to assess the impact of a real appreciation of the renminbi versus the US dollar in a global model. Our results indicate that real appreciation of the renminbi decreases the level of Chinese GDP slightly and the long‐run effect is also negative for many countries exporting (e.g. raw materials) to China.     

The 1997 Asian Currency Crisis,Financial Linkages,and the Monetary Policy of Japan

The evidence is examined that excessively liberal monetary policy by the Bank of Japan, before and after the financial collapse of Japan in 1992, may have led other East Asian economies into “over‐borrowing” and speculative investments, prior to the currency crisis in 1997–98. The authors test for cointegration and Granger causality between Japanese money supply M1 and the domestic investment of eight East Asian economies and Australia. US and German money supplies are also used as a benchmark. There is strong evidence that there are long‐ and short‐run causal relationships between the Japanese money supply and the domestic investment of the Asian crisis‐inflicted economies prior to 1997.     

THE J CURVE: CHINA VERSUS HER TRADING PARTNERS

The short‐run effects of currency depreciation are said to be different from its long‐run effects. In the short run, the trade balance deteriorates and improvement comes after some time; hence, the J‐curve phenomenon. Previous studies that tested the response of the trade balance to exchange rate changes in China employed aggregate trade data and provided mixed results. Indeed, most of them concluded that real depreciation has no long‐run impact on the Chinese trade balance. In this paper, we disaggregate the data by country and using recent advances in time series modelling estimate a trade balance model between China and her 13 major trading partners. We show that real depreciation of the Chinese currency has a favourable impact on her trade balance with a few partners, especially the USA. Not much support is found for the J‐curve hypothesis.     

SYNCHRONIZATION OF ECONOMIC SHOCKS BETWEEN GULF COOPERATION COUNCIL AND UNITED STATES,EUROPE, JAPAN,AND OIL MARKET: CHOICE OF EXCHANGE RATE REGIME†

Using a structural vector autoregression (SVAR) with block exogeneity, this study examines the impacts of external shocks originating from the United States, the European Union, Japan, and the oil market as well as those of the regional shocks, on the oil‐rich countries of the Gulf Cooperation Council (GCC), viewed as a prospective monetary union. It takes into account the implications of the shock impacts for selecting an appropriate common exchange rate arrangement. The SVAR variance decomposition and impulse response analyses strongly underscore the relative impacts of the global shocks over the regional ones. The findings imply that the world's two major currencies, the U.S. dollar and the euro, should figure highly in a GCC's common basket of currencies. Accordingly, a transitional movement to a more flexible exchange rate arrangement such as a basket peg may be desirable for these trade‐dependent economies in the long run, as is argued in the optimal currency literature for developing countries.

Is there a “reform fatigue” in the euro area?

The absence of monetary policy within a currency union increases the need for structural reforms that make the participating economies more flexible. However, the absence of exchange rate risk with respect to the other members of the union may reduce the urgency for such reforms. A number of other considerations also suggest that theory is ambiguous about the impact of participating in a currency union on progress in structural reforms. This paper addresses this issue empirically for the euro area. The results suggest that reforms in the euro area seem to have decelerated following the introduction of the euro, but from a fast pace. The paper discusses a number of possible explanations, including “reform fatigue,” the absence of “market punishment,” and “good-times” complacency. Estimates from an empirical growth model suggest that the slowing of reforms may slow down annual output growth by up to 0.2%. However, the results are preliminary and depend on the area of reform considered. Furthermore, the reform dynamics may change with the euro area starting slowing at the end of 2007.     

Fiscal consolidation under imperfect credibility

This paper examines the effects of expenditure-based fiscal consolidation when credibility as to whether the cuts will be long-lasting is imperfect. We contrast the impact limited credibility has when the consolidating country has the means to tailor monetary policy to its own needs, with the impact when the country is a small member of a currency union with a negligible effect on interest rates and on nominal exchange rates of the currency union. We find two key results. First, in the case of an independent monetary policy, the adverse impact of limited credibility is relatively small, and consolidation can be expected to reduce government debt at a relatively low output cost given that monetary policy provides more accommodation than it would under perfect credibility. Second, the lack of monetary accommodation under currency union membership implies that the output cost may be significantly larger, and that progress in reducing government debt in the short and medium term may be limited under imperfect credibility.     

The optimality of a gulf currency union: Commonalities and idiosyncrasies

A high degree of shared national elements that drive the bulk of observed output volatility between countries is generally seen as a necessary prerequisite for the formation of a successful monetary union. This is because countries in a monetary union accept a one-size-fits all, resigning regions to policies that are based on some aggregate macroeconomic target rather than a country-specific one. For this reason, the cost of monetary union membership depends on the incidence of asymmetric (nation-specific) shocks rather than symmetric, or common shocks. This criteria is examined for the Gulf Cooperation Council (GCC) countries, who reaffirmed plans for the implementation of a single currency. This paper quantifies, using structural factor models with common factor restrictions, changes in output synchronisation, the importance of common factor or idiosyncratic shocks between the regions, and the synchronisation of these shocks across the GCC as well as the implications for GCC-wide macroeconomic policy at short-to-medium term horizons. Despite current difficulties in fulfilling the convergence criteria goals to monetary union, the results show the synchronisation of output growth fluctuations between economies of the GCC to have increased over the past 25 years. This paper also finds that a fairly sizeable proportion of output fluctuations in business cycle frequencies are driven by a common component that, to some degree, reflects U.S. monetary policy and U.S. demand shocks as well as changes in crude oil prices.     

Macroprudential policy and the inward transmission of monetary policy: The case of Chile,Mexico, and Russia

This paper studies whether domestic macroprudential policy may attenuate the inward transmission of monetary policy shocks from the United States to domestic bank lending growth in three emerging market economies—Chile, Mexico, and Russia. Identification relies on banks’ heterogeneous exposure to prudential policies and the fact that foreign monetary policy shocks are exogenous from the perspective of these economies. After analyzing the effects of the aggregate domestic prudential policy stance, we focus on specific prudential policies targeting mortgage and consumer loans, as well as foreign‐currency deposits. Although our overall results are mixed, we find evidence that the strength of international monetary policy spillovers varies depending on the stance of domestic macroprudential policy. In particular, a tighter reserve requirement stance over foreign‐currency deposits in Chile dampens the effect of an international monetary policy shock on domestic local‐currency lending, but reinforces that on foreign‐currency lending, whereas in Russia, it dampens the effect on both local‐currency and foreign‐currency lending, although to different degrees. Prudential policies targeting the asset side of banks’ balance sheets, such as mortgage loans or consumer credit, are found to amplify international monetary policy spillovers in some cases and attenuate it in others, depending on the country context.     

CURRENCY UNION WITH OR WITHOUT BANKING UNION

We build a symmetric two‐country monetary model with credit to study the interplay between currency integration and credit markets integration. The currency arrangement affects credit availability through default incentives. We capture credit markets integration by the extra cost incurred to obtain credit for cross‐border transactions and, with the euro area context in mind, label as banking union a situation where this cost is low. For high levels of the cross‐border credit cost, currency integration may magnify default incentives, leading to more credit rationing and lower welfare. The integration of credit markets restores the optimality of the currency union.     

The Success of Currency Reforms to End Great Inflations: An Empirical Analysis of 34 High Inflations

Abstract. The estimation of an ordered probit model for currency reforms attempting to end 31 hyperinflations and three huge inflations of the twentieth century shows that the introduction of an independent central bank and the adoption of a credibly fixed exchange rate are crucial for the success of a currency reform. In addition, currency reforms are demonstrated to be more difficult in centrally planned economies than in market economies.     

What Does the Taylor Rule Say About a New Zealand–Australia Currency Union?*

It has been suggested that the New Zealand economy may have similar characteristics and face similar shocks to some Australian states, so lowering the costs of a trans‐Tasman currency union. We test this, under the assumption that differences in Taylor rule‐implied interest rate paths for different regions give an indication of differences in aggregate shocks that hit different economies. We compare implied Taylor rule interest rates for each of the Australian states to implied Taylor rule rates for New Zealand. We also compare them to realised 90‐day rates. We find that the Taylor rule‐implied rates in Australian states and in New Zealand are similarly correlated with actual Australian interest rates.     

Commitment and the adoption of a common currency*

In contrast to Mundell's inquiry on the optimality of currency areas, this article aims to understand under what circumstances a Pareto‐dominant monetary union will be established. Using a multicountry overlapping generations model, we highlight gains from monetary union arising from reduced transactions costs and lower inflation. Despite these gains, countries acting independently will impose barriers to exchange through local currency restrictions, thereby creating transactions costs and providing an incentive for inflation. Therefore, the gains from monetary union are most likely to be lost without collective effort.
