Trade,Determinants, and Causality: A Case of Hong Kong's Exports to The United States

This paper examines recent development in Hong Kong's exports to the United States. It explains the trade flows by estimating five demand-equations for exports. Besides, vector autoregressions are fitted to test the causal relationship among exports, exchange rates and income. Our study suggests that a sustained high growth rate of Hong Kong's exports of principal commodities to the United States contribute to the chronical bilateral trade surplus for Hong Kong. Variations in income and exchange rates, the major determinants of Hong Kong's exports, “cause” exports to change as indicated in the causality test. [420]     

Foreign output shock in small open economies: A welfare evaluation of monetary policy regimes

We examine the impact of negative foreign output shocks, which entail negative demand side effects by lowering exports and positive supply side effects by lowering oil prices, on the welfare of non-oil producing, small open economies under five exchange rate and monetary policy regimes. We use a dynamic stochastic general equilibrium model with parameter values calibrated for Hong Kong, Israel, Singapore, South Korea and Taiwan. We find that welfare levels among the five policy regimes depend on the economy's share of oil imports in world oil consumption. Hong Kong, Singapore and Israel, which have smaller shares, maximize welfare under the Taylor rule, which targets both CPI inflation and real output. South Korea, with higher shares, and Taiwan, with more rigid prices, maximize welfare under real output targeting. CPI inflation targeting, nominal output growth targeting and fixed exchange rate regimes generate lower welfare. However, optimal monetary policy, which generates the highest welfare, gives greater weight on real output than CPI inflation.     

影响中国电子行业出口决定因素的经验分析

本文利用中国电子工业子行业面板数据实证分析1999—2002年期间该行业出口的决定因素,特别是外商直接投资(FDI)的作用。我们发现FDI尤其是来自港澳台的FDI和规模经济对出口有正向作用。我们同时发现国有资本份额与出口负向相关,而资本密集度、研发和人力资本并不是影响中国电子行业出口的重要因素,表明中国的电子企业大多仍处于国际产品分工链的低端。本文有两个原创性贡献:第一是区分不同国别(地区)FDI对中国电子产品出口影响的差异,并发现港澳台地区资本较西方国家资本对中国电子产品出口影响更大;第二是发现劳动力成本水平因素影响FDI对出口作用程度的大小。这些结果具有重要的政策涵义。     

Exchange rate volatility and exports from East Asian countries to Japan and the USA

The purpose of this article is to investigate the impact of exchange rate volatility on exports in four East Asian countries (Hong Kong, South Korea, Singapore, and Thailand). Specifically, this article aims at determining whether the bilateral real exchange rate volatility between an East Asian country and its trading partner negatively affects the exports of the East Asian country. Considering the dominant roles of the USA and Japan as trading partners of those East Asian countries, this article focuses on the quarterly export volumes of East Asian countries to the US and Japan for the period from 1981 to 2004. Except for the case of Hong Kong's exports to Japan, cointegration tests and estimations of error correction models indicate exchange rate volatility has negative impacts on exports either in the short-run or in the long-run, or both. On the other hand, the real GDP of importing countries and depreciation of real bilateral exchange rates turn out, in general, to have positive effects. Of special interest is the finding that the impact of the exchange rate volatility does not show any stylized differences depending on whether the importing country is Japan or the USA, even though dollar invoicing dominates in East Asia.     

Exchange rate volatility and export growth in Nigeria

This article examines the impact of exchange rate volatility on Nigeria's exports to its most important trading-partner–the United States over the quarterly period January 1980 to April 2001. Using cointegration and vector error correction (VECM) framework, empirical tests indicate the presence of a unique cointegrating vector linking real exports, real foreign income, relative export prices and real exchange rate volatility in the long run. Furthermore, the results show that increases in the volatility of the real exchange rate raise uncertainty about profits to be made which exert significant negative effects on exports both in the short- and long-run. Our results also show that improvements in the terms of trade (represented by declines in the real exchange rate) and real foreign income exert positive effects on export activity. Most importantly, we found that the trade liberalization and economic reform policies implemented in the post-1986 structural adjustment period contributed to Nigeria's export performance. Overall, our findings suggest that Nigeria's exporting activities can be further boosted by policies aimed at achieving and maintaining a stable competitive real exchange rate.     

Exchange‐rate volatility and US–Hong Kong industry trade: is there evidence of a ‘third country’ effect?

In an effort to better understand the determinants of trade flows worldwide, researchers have recently incorporated external volatility (in addition to that of the partners’ bilateral exchange rate) into their models. The so‐called ‘third country’ effect is present if adding this term changes the bilateral volatility estimates that are found when external volatility is omitted. This study examines US exports to Hong Kong for 143 industries, and imports from Hong Kong for 110 industries, and finds two key results. First, expected inflation due to Hong Kong's dollar peg leads to increased US exports in a large number of industries. Second, comparing our results with those of a previous study shows strong evidence of a ‘third country’ effect, especially for US imports. Nonparametric tests suggest that these effects differ by sector: for both exports and imports. Manufacturing industries that enjoy a large trade share are less likely to experience this effect once external volatility is incorporated into the analysis.     

Exchange rates change,asset-denominated currency difference and stock price fluctuation

This paper examines differences in the connectedness between exchange rates and stock prices for companies with different asset currencies on the Hong Kong stock market, and it seeks to explain those differences by proposing a hypothesis on asset-denominated currency difference. Under a framework of investor heterogeneity, we establish a dynamic, discrete theoretical model to analyse the connectedness between exchange rates, the stocks of local Hong Kong companies, the stocks of companies from the mainland and foreign exchange interventions. Using monthly data from January 2000 to August 2018, we adopt the time-varying parameter vector auto-regression (TVP-VAR) model to empirically study the dynamic relationships between exchange rates and the prices of both Hong Kong-based and mainland-based stocks. The results show significant differences in the ways that exchange rates and prices for the two types of stocks are linked. The exchange rates are positively correlated with mainland stocks and negatively correlated with Hong Kong stocks. Moreover, foreign exchange intervention is found to be an effective means for stabilising exchange rates, although such intervention tends to increase stock volatility.

On the Transmission Mechanism of Monetary Constraints to the Real Side of the Economy

Contrary to the predictions of the theory underlying international finance, inflows of capital triggered by financial liberalisation have neither equalised real interest rates nor increased income growth in many emerging economies. We explain this puzzle by developing a model that combines the balance‐of‐payments constraint approach to economic growth with a less stringent version of the real interest rate parity hypothesis. The model’s foundations are based on robust empirical findings or well‐established macroeconomic models. We show that a perverse combination of income elasticities of demand for imports and exports generates slow income growth and high real interest rates. As domestic income grows and imports rise faster than exports, the real exchange rate is expected to depreciate in order to clear the balance of payments (or the foreign exchange rate market). An incipient capital outflow arises and interest rates increase. Faster adjustment in capital rather than in the goods market therefore generates a higher real interest rate differential between the domestic small open‐economy and the rest of the world. The long run analysis shows that a constant degree of risk aversion implies a positive equilibrium real interest rate differential that affects economic growth. A permanent increase in default risk driven by persistent current account imbalances thus impacts on long run growth. The model’s results are illustrated with evidence from the three major Latin America economies: Argentina, Brazil and Mexico.     

A DYNAMIC FACTOR MODEL OF ECONOMIC ACTIVITY IN HONG KONG

Abstract. This paper applies the single‐index dynamic factor model developed by J. H. Stock and M. W. Watson to construct (almost) real‐time estimates of economic activity in Hong Kong. The Hang Seng index, a residential property price index, retail sales and total exports are used as coincident indicators. Principal component analysis is first used to obtain an impression of the common component of the indicator series. This component and the dynamic factor identified by the Stock–Watson methodology are strongly correlated and seem to capture economic fluctuations in Hong Kong reasonably well.     

A Tale of Two Currencies: the Asian Crisis and the Exchange Rate Regimes of Hong Kong and Singapore

Hong Kong has maintained a pegged exchange rate since 1983, while Singapore has been on a floating regime since the early 1970s. This paper provides an interpretation of the different performance of the Hong Kong and Singapore economy that could be attributable to the differences in their exchange rate regime. We develop a model that can help to interpret the differences in both the longer run trends in inflation and real exchange rates in Hong Kong and Singapore as well as the short differences in macroeconomic and real exchange rate volatility. The difference in the response of the two economies to the Asian crisis is also consistent with our model.     

影响中国出口贸易的主导因素分析

本文采用自回归分布滞后模型和边限检验方法,利用1997年1季度至2008年4季度的数据估计了中国进出口贸易需求的收入弹性、价格弹性和汇率弹性,结果发现国外收入变化是影响中国出口的主要因素,产品价格对出口的影响较小,而人民币汇率波动对出口的影响不确定。因此,如果采取低价格促进出口的措施,不仅是低效的,而且是得不偿失的。转向以内需驱动为主的经济增长方式,是中国经济发展的必然战略选择。     

Exchange rate and foreign GDP elasticities of Swiss exports across sectors and destination countries

This article uses a detailed breakdown of Swiss trade flows to identify how the impact of the two main determinants of Switzerland’s exports – foreign demand and the real exchange rate – varies across sectors and export destinations. Our main findings are that (i) both foreign demand and exchange rate elasticities vary substantially across both export sectors and export destinations. (ii) Foreign demand trends are more important for structural considerations than the exchange rate. This is due to the fact that exports of the two largest export sectors are relatively sensitive to long-run foreign demand developments while they are relatively insensitive to changes in the exchange rate. (iii) The sectoral structure of Switzerland’s exports has shifted towards goods that have a lower short-run demand elasticity and a higher long-run demand elasticity. Goods exports are thus less influenced by business cycle fluctuations while they benefit more from long-term growth trends. (iv) The export share of sectors with a relatively low exchange rate elasticity has increased. However, this result is mainly driven by the strong rise in exports of chemicals and pharmaceuticals as well as precision instruments and watches, which are also the two important sectors responsible for the Swiss trade surplus.     

International trade and macroeconomic dynamics: The case of U.S. bilateral trade with G-7 countries

The short- and long-run effects of exchange rates, income, interest rates and government spending on U.S. bilateral trade with the other G-7 countries are investigated using an autoregressive distributed lag (ARDL) model. The primary contribution of this study is to consider separating the analysis of exports and imports in an integrated model that empirically encompasses four major schools of thoughts – elasticity, Keynesian income, absorption and monetary approaches – in order to identify macroeconomic linkages to U.S. bilateral trade with the other G-7 countries accurately. Results suggest that, in both the short- and long-run, U.S. imports and exports are highly sensitive to changes in U.S. and foreign income, while U.S. imports and exports are relatively insensitive to changes in bilateral exchange rate. It is also found that both exports and imports are more responsive to changes in government spending than changes in interest rates in both the short- and long-run.     

Dynamic linkages between exchange rates and stock prices: Evidence from East Asian markets

This study examines dynamic linkages between exchange rates and stock prices for seven East Asian countries, including Hong Kong, Japan, Korea, Malaysia, Singapore, Taiwan, and Thailand, for the period January 1988 to October 1998. Our empirical results show a significant causal relation from exchange rates to stock prices for Hong Kong, Japan, Malaysia, and Thailand before the 1997 Asian financial crisis. We also find a causal relation from the equity market to the foreign exchange market for Hong Kong, Korea, and Singapore. Further, while no country shows a significant causality from stock prices to exchange rates during the Asian crisis, a causal relation from exchange rates to stock prices is found for all countries except Malaysia. Our findings are robust with respect to various testing methods used, including Granger causality tests, a variance decomposition analysis, and an impulse response analysis. Our findings also indicate that the linkages vary across economies with respect to exchange rate regimes, the trade size, the degree of capital control, and the size of equity market.     

MACROECONOMIC VOLATILITY AND COUNTERFACTUAL INFLATION‐TARGETING IN HONG KONG

The present paper evaluates macroeconomic adjustment in Hong Kong with an estimated dynamic stochastic general equilibrium (DSGE) model under a fixed exchange rate regime. We find that exports and world inflation shocks are the dominant sources of GDP volatility, with the risk premium taking on importance during the Asian crisis after 1997. A counterfactual simulation, assuming a flexible exchange rate regime with inflation targeting, shows that inflation would have decreased slightly, but interest‐rate volatility would have increased significantly. The welfare gains from switching out of the currency board system appear to be marginal.     

Long–run price and income elasticities of demand for Hong Kong exports: a structural cointegrating VAR approach

This article revisits a system of export volume and price equations to estimate the long–run price and income effects in the demand for Hong Kong's exports. Using a recently developed restricted cointegrating VAR approach it tests theorybased restrictions and obtains estimates of the long–run structural coefficients. The estimation results provide supporting evidence for the theory–based restrictions and suggest that the demand for Hong Kong's exports is both price and income elastic. This article is therefore able to present a long–run model of Hong Kong's exports that is both theory and data consistent, and long–run elasticities that are economically interpretable. The short–run properties of the model are illustrated by means of persistence profiles, which confirm the cointegrating vectors tendency of convergence.     

Structural changes in exports of an emerging economy: Case of Turkey

This paper indicates that Turkish exports are subject to structural changes as Turkey integrates into global production networks. Integration, which leads vertical specialization in production and changes in the commodity composition of Turkish exports in favor of non-traditional commodities, paces up during economic reform periods. As the export shares of non-traditional commodities, which have higher import and income sensitivity but lower real exchange rate elasticity, increases, coefficients of the aggregate export function change accordingly. Nevertheless, high import and income elasticity of exports imply that the global growth pattern plays a significant role in determining exports of Turkey.     

Coffee exports and industrialization in Brazil

We investigate the dynamic relationship between coffee exports and machinery imports in Brazil from 1869 to 1939. Our tests reveal cointegration and bidirectional causality in the temporal sense. This evidence suggests that foreign exchange real revenues from coffee exports were important for the onset of industrialization, as machinery imports proxy for real investment demand. Capital growth, in turn, also helped to boost the country’s exports.     

港澳台—中国对外开放的独特优势

中国对外开放三十多年,经济发展速度之快举世瞩目。作为对外开放的典型标志,对外贸易和引进外资更是突飞猛进,成为世界贸易排名第二、发展中国家引进外资最多的经济体。中国对外开放之所以取得如此成就,港澳台地区功不可没,甚至可言,如果没有同文同种的新型工业化经济体港澳台与中国内地的密切经贸往来,中国对外开放将经历较长的探索阶段。港澳台地区是中国对外开放最早的也是迄今最主要的投资者,是中国承接国际产业转移最重要的推动者,也是中国进军国际市场的最重要中介与平台。无论是珠三角经济带还是长三角经济带,港澳台企业都是重要的支柱力量。中国最早的区域经济一体化协议,是与香港和澳门签署的,今后中国的自贸区战略,港澳台地区将成为核心。     

Professors and hamburgers: an international comparison of real academic salaries

In recent years, academic staff unions and associations have argued for higher salaries for academics on the grounds that existing salaries have not kept pace with inflation, are well below commercial salaries and, most glaringly, are much lower than the salaries of their overseas counterparts. However, most international comparisons are made based on exchange rate conversions, which is inappropriate since purchasing power differentials are only reflected in exchange rates in the long term. Furthermore, the volatility of exchange rates make such conversions highly inaccurate. A comparison is provided of real academic salaries by converting the nominal salaries in each country to their purchasing power equivalents, using the Big Mac Index. Our results show that real academic salaries are highest in Hong Kong and Singapore, relative to the developed countries, while Hong Kong tax and social security deductions are lowest. Furthermore, real salary levels, combined with intrinsic considerations such as the quality-of-life, indicate that Canada and New Zealand are unattractive places for visiting/migrating academics, while Australia and the USA are relatively attractive. It is suggested that these findings could be of use to policy-makers and academic unions in salary negotiations, as well as academics making relocation decisions.
