Causality Between Exports,Imports and Income In Trinidad and Tobago

This study examines the relationship between exports, imports and income in the economy of Trinidad and Tobago, using the methodology of Granger causality and error correction modeling. Our results show that there is unidirectional Granger causation from exports to income (GDP), and bidirectional causation between exports and imports and imports and income. The Economy of Trinidad and Tobago is a petroleum exporting economy where oil-export booms raise income levels, but this is usually followed by a slump. The bivariate models should be interpreted with caution because of the possibility of omitted variable bias. [F14, C22]     

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.     

Export and import composition as determinants of bilateral trade in goods: evidence from Russia

Conventional theory and several empirical studies state that incomes and exchange rates are the key determinants of the trade balance. Here, we argue that export and import composition are also key explanatory variables because some goods are inelastic and/or with a high added value, directly and indirectly affecting income and price elasticities and trade balance. Thus, if exports and/or imports significantly consist of price inelastic products, then, a positive and a negative effect, respectively, should be expected on the trade balance. Using bilateral trade data and dynamic panel models, we found that the ratio of exports of crude petroleum and natural gas (price inelastic goods) to total exports is significantly and positively associated with the Russian trade balance in goods. For its part, Russian imports of high-tech goods (income elastic and price inelastic with a high added value) show a negative association. The goods balance of Russia also responded to changes in relative income, but there is only weak evidence of reactions to changes in the exchange rate. These findings partially explain the persistent surplus in the Russian trade balance and current account.     

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。     

Exports,Imports and Income in Taiwan: An Examination of the Export Led Growth Hypothesis

Cointegration and vector autoregression are used to examine relationships among exports, imports, and income in Taiwan from 1971 to 1995. These three series are cointegrated. There is bidirectional Granger causality between exports and imports, and between imports and income. Impulse responses and variance decompositions uncover only weak links from exports to income. The export led growth hypothesis is not supported for Taiwan during this period of rapid growth. [F1, F4, O0]     

How Elastic is East Asian Demand for Consumption Goods?

This paper investigates import demand in East Asia. Estimating exchange rate elasticities for countries in the region is difficult because many imports are used to produce goods for re‐export. An exchange rate appreciation that reduces East Asian exports will also reduce the demand for imported inputs that are used to produce exports. To correct for this bias this paper examines consumption imports, since these goods are intended primarily for the domestic market. Results from several specifications indicate that currency appreciations and increases in income in East Asian countries would significantly increase imports into the region.     

Exchange Rate,Income Distribution and Technical Change in a Balance-of-Payments Constrained Growth Model

This article develops a formal model that accounts for the net effect of an exchange rate devaluation on the long-term balance-of-payments constrained growth rate. Such a model investigates how a currency devaluation impacts on the home country non-price competitiveness via changes in income distribution and the rate of technological innovation. The model is built upon two plausible hypotheses. First, it is assumed that the rate of technological innovation is directly related to the income elasticity of demand for exports and inversely related to the income elasticity of demand for imports. Second, it is assumed that a redistribution of income between labor and capital has an ambiguous direct impact on the income elasticities ratio. The model shows that the net impact of a currency devaluation on growth can go either way depending on the institutional framework of the economy.     

The impacts of China on economic growth: Evidence for Brazil,Chile, and Peru

This study empirically analyzes the direct impacts derived from the swift increase in exports to China (referred to as “the impact of China”) on the economic growth of three selected South American countries, Brazil, Chile, and Peru, during the commodity boom between 2001 and 2008. The results stemming from the balance-of-payments-constrained growth model suggest that the magnitude of China’s impact was less than 1 percent, although it ranged from the largest to the second largest impact among all trading partners for the three countries. The estimated balance-of-payments growth rate of domestic income is lower than the real growth rate of domestic income. This is because the growth rates of the export volumes were not sufficient even during the commodity boom, on account of the continued increasing trends of income elasticity of demand for imports. Furthermore, the income elasticities of demand for imports from China were especially high. Therefore, the three countries will continue to face further increase in the income elasticity of demand for imports as well as a stagnant growth rate of export volumes. Thus, the balance-of-payments position will continue to be the main growth constraint for these countries.     

Are shocks to the terms of trade shocks to productivity?

International trade is frequently thought of as a production technology in which the inputs are exports and the outputs are imports. Exports are transformed into imports at the rate of the price of exports relative to the price of imports: the reciprocal of the terms of trade. Cast this way, a change in the terms of trade acts as a productivity shock. Or does it? In this paper, we show that this line of reasoning cannot work in standard models. Starting with a simple model and then generalizing, we show that changes in the terms of trade have no first-order effect on productivity when output is measured as chain-weighted real GDP. The terms of trade do affect real income and consumption in a country, and we show how measures of real income change with the terms of trade at business cycle frequencies and during financial crises.     

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.     

The role of exports,FDI and imports in development: evidence from Sub-Saharan African countries

The disappointing economic performance of Sub-Saharan African (SSA) economies in the late 1980s prompted reforms in foreign trade and Foreign Direct Investment (FDI) in the early 1990s. Using the Autoregressive Distributed Lag (ARDL) approach and Pedroni panel estimation procedures that allow for heterogeneity, this study found that exports and FDI have a significant impact on economic growth. Granger-type causality tests show the interrelatedness of exports, FDI, imports and income variables. The results also provide evidence of a two-stage causal chain of exports, imports and income. This article calls for more market-oriented policy reforms in SSA countries.     

Cross-price effects in demand between exports and imports

This paper extends the Bickerdike-Robinson-Metzler elasticities model to include cross-price effects in demand between exports and imports, and compares the extension to the Kemp general-equilibrium model. In the extended elasticities model, positive cross-price influences impede adjustment; in the general-equilibrium model, however, such influences are part of the uniform gross-substitutability condition that assures stability. This difference arises because income and own-price effects for nontraded goods are constrained to zero in the elasticities model. Evidence of the demand for exports and imports for the United States indicates significant crossprice effects.     

The PRC's long-run growth through the lens of the export-led growth model

We explain China's remarkable growth performance over the last three decades through an export-led growth (ELG) model, where countries need to export to pay for their imports. We show that China's actual long-run growth rate is well approximated by its balance-of-payments equilibrium (BOPE) growth rate, defined as the long-run growth rate consistent with current account equilibrium. This growth rate is given by the ratio of the growth rate of exports to the income elasticity of imports. We estimate the latter using the Kalman filter, which allows us to obtain a time-varying estimate of China's BOPE growth rate. We find that the average value of China's BOPE growth rate during 1981–2016 was about 11 percent but fluctuated significantly over time and declined notably after 2007. It is estimated to be 5.9 percent in 2015. We then discuss the determinants of China's BOPE growth rate and of the income elasticity of imports, with the help of the Bayesian Model Averaging technique. The analysis highlights the role of the composition of aggregate demand as the main driving force, both for its direct effects on the income elasticity of imports, and for the indirect effects on export growth via capital accumulation, in particular fixed asset investment. Our analysis has important implications to understand China's transition to a “New Normal” of a lower growth rate and the effects of the external and internal rebalancing strategy pursued from the early 2000s.     

Trade and Rural-Urban Income Inequality: Evidence from China

Using the provincial panel data from 1978 to 2007, this paper makes an empirical analysis of the relationship between international trade and rural-urban income inequality in China. The results show that international trade has a fundamental impact on rural-urban income inequality. For the whole country, the development of international trade from 1978 to 2007 enlarged the rural-urban income gap. During the three different periods (defined in section 3.3), the impact was also noticeable in terms of extent, direction and significance respectively at the national and regional levels. During the three periods, the relationship has an inverted “U” shape for China as a whole, central China and western China, but for eastern China the relationship has a “U” shape. At the same time, exports and imports have different influences on the rural-urban income gap in China, the influences were also different across regions; and the imports has had a more significant influence on these regions than exports has had.     

Trade flows,relative prices,and effective exchange rates: a VAR on Ethiopian data

The dynamic response of trade flows to price and effective exchange rate changes is examined via VAR using quarerly data from Ethiopia for the period 1973(i)–1985(iv). The results show one-way Granger-causality running from prices and exchange rates to imports and exports without significant feedback. Imports and exports exhibit similar response patterns to unexpected changes in relative prices and exchange rates. The responses of imports and exports are larger and the adjustment takes longer when relative prices rather than exchange rates caused a change in international prices. In the long-run, changes in prices account for a larger percentage of the forecast error variances in imports and exports than exchange rate changes. It is shown that devaluation may have an initial adverse effect on the trade balance.     

Tourism,trade and growth: the case of Cyprus

Although the relationship between international trade and economic growth has found a wide application area in the literature over the years, this can not be said about tourism and growth or trade and tourism. This study employs the bounds test for cointegration and Granger causality tests to investigate a long-run equilibrium relationship between tourism, trade and real income growth, and the direction of causality among themselves for Cyprus. Results reveal that tourism, trade and real income growth are cointegrated; thus, a long-run equilibrium relationship can be inferred between these three variables. On the other hand, Granger causality test results suggest that real income growth stimulates growth in international trade (both exports and imports) and international tourist arrivals to the island. Furthermore, growth in international trade (both exports and imports) also stimulates an increase in international tourist arrivals to Cyprus. And finally, real import growth stimulate growth in real exports in the case of Cyprus.     

A short-run general equilibrium model for a small,open economy

This paper introduces some features observed in developing countries into a CGE model. In particular, quantitative restrictions on exports and imports are incorporated and quota-derived rents are included as a source of income. The economy is assumed to be small only on the import side, such that export prices are endogenous. A distinction between traded and treadeable goods is introduced, together with the possibility of ‘water in the tariff’. Thus, the law of one price need not hold. Another key feature is the modelling of supply with unutilized capacity. Thus, excess demands clear by price changes, output adjustments, or imports, depending on the degree of capacity utilization, the tradeability of the good, and the trade regime. An empirical application of the model shows that in a GE context, import quotas can worsen the trade balance while lowering real income and the real wage rate.     

外国直接投资对我国国际贸易贡献的实证分析

FD I与我国进出口贸易总额、出口总额、进口总额之间都存在长期均衡关系,而且我国出口贸易的FD I弹性系数要大于我国进口贸易的FD I弹性系数,即FD I对我国出口贸易的贡献要大于其对进口贸易的贡献。通过建立的误差修正模型,研究了FD I与进出口贸易总额、出口总额、进口总额之间由非均衡向长期均衡状态动态调整的过程。     

LABORS INFLUENCE ON THE BALANCE OF THE USA'S MERCHANDISE ACCOUNTS

The results found here indicate that American labor does influence importantly the level of imports and exports of manufactures in the US. In particular, imports tend to be lower and exports tend to be higher in those industries in which higher skilled American workers are used more abundantly. Moreover, labor efficiency and productivity also influence inversely the level of imports and directly the level of exports.     

The Greek economy under the twin-deficit pressure: a demand orientated growth approach

This paper uses an alternative growth approach in line with Thirlwall’s model in order to predict economic growth in Greece taking into account internal and external imbalances caused by public deficit/debt and lack of trade competitiveness. It is shown that the simple Thirlwall’s Law (given by the product of the ratio of the income elasticities of demand for exports and imports, and the growth of foreign demand) over-predicts real growth in Greece while the more complete extended model, makes a closer prediction which is consistent with the high deficit/debt and current account deficit experienced in this country. The simulation approach shows that the most efficient policy to attain higher growth is to reduce external imbalances while policies to reduce internal imbalances are low growth enhancing.
