Asymmetric effects of oil price changes on the balance of trade: Evidence from selected African countries

The main new contribution of this study was to delve into the asymmetric impacts of changes in oil prices on the trade balance in the framework of six major African economies. To tackle this topic carefully, we employ three measures of external balances—oil, non‐oil and total trade balances, and assess the asymmetric response of the external balances of those six economies to oil price changes in the short and long run. Like most previous studies, we first assume the impacts of oil price fluctuations to be symmetric and employ the linear autoregressive distributed lag (ARDL) method to explore the topic. We then separate oil price hikes from oil price plunges and implement the non‐linear ARDL method to reveal that the price of crude oil has a vital role to play in the trade balances for those six African economies. Further, there is evidence of significant asymmetric impacts of oil prices typically on the oil trade balance of Africa's top oil producing countries. For the non‐oil and total trade balances, in contrast, there is little evidence of the asymmetry of oil price changes.     

Oil shocks and external balances

We provide estimates of the effects of demand and supply shocks in the global crude oil market on several measures of oil exporters' and oil importers' external balances, including the oil trade balance, the non-oil trade balance, the current account, capital gains, and changes in net foreign assets (NFA). First, we show that the effect of oil demand and supply shocks on the merchandise trade balance and the current account, which depending on the source of the shock can be large, depends critically on the response of the non-oil trade balance. Our results provide evidence of an intermediate degree of international financial integration. Second, we document the presence of large and systematic valuation effects in response to these shocks. Valuation effects overall tend to cushion the effect of oil demand and supply shocks on the NFA positions of oil exporters and oil importers. Third, we quantify the overall importance of global business cycle demand shocks as well as oil-market specific demand and supply shocks for external balances.     

The impact of oil price movements on bank non-performing loans: Global evidence from oil-exporting countries

It is generally believed that economic and financial performance in oil-rich countries are interlinked to oil price movements. On this assumption, we consider whether oil prices shocks have any impact on bank non-performing loans (NPLs), and if so, whether the effect is homogenous across banks. This paper addresses these questions by applying a dynamic GMM model on data from 2310 commercial banks in 30 oil-exporting countries over the period 2000–2014. Three main results emerge. First, changes in oil prices do have a significant impact on bank NPLs: A rise (fall) in oil prices is associated with a decrease (increase) in NPLs. Second, oil prices shocks have asymmetric effects on bank problem loans, with negative oil price movements generally have a greater impact than positive oil price movements. Third, the unfavourable impact of adverse oil prices shocks on the quality of bank loans tends to be more pronounced in large banks. Overall, these robust results favour the adaptation of appropriate macroprudential policies and diversification of the economy, in order to mitigate the adverse impact of oil prices shocks.     

Prospects for the international oil market

The OPEC price conference in Geneva on May 25–26, 1981 did not resolve the disagreement among OPEC member countries over official prices. As a result of this stalemate, Saudi Arabia with its intention to moderate prices will in the foreseeable future probably not be prepared to make substantial reductions in its high volume of production with which it puts pressure on prices. What short- and medium-term perspectives for the international oil market arise from this situation?     

Modeling the employment–oil price nexus: A non-linear cointegration analysis for the U.S. market

ABSTRACT

Theoretically, fluctuations in oil prices are expected to affect production costs and may force businesses to delay their investment decisions, triggering pressures on employment. Following these theoretical notions, this paper investigates the asymmetric impact of oil prices on employment (measured as total employment, male employment, and female employment), in a nonlinear cointegration structure for the U.S. market. In doing so, this paper adopts the nonlinear autoregressive distributed lags (NARDL) model to shed light on such asymmetric association, as the NARDL model recently emerged as a new direction in examining nonlinear cointegration and asymmetry. The empirical findings document a long-run asymmetric effect in case of total employment and male employment only. Furthermore, the short-run asymmetric effect was detected for all three employment categories. As a final point, the Granger Causality test documents a unidirectional causality running from oil price decrease to both total employment and male employment.     

The Effects of Oil Price Shocks on Output

This analysis explores the effects of oil price shocks on U.S. economic growth. We begin with a well-known model developed by James Hamilton, consider refinements to his definition of an oil price “shock,” and then explore alternatives to his basic reduced-form model. We find that a structurally inspired error-correction model for non-farm business output, which allows for oil price changes to have both long-run and short-run effects, performs better than the basic reduced-form model and also shows significantly smaller adverse effects of rising oil prices. Our preferred model suggests that oil prices reduced GDP growth by about 0.4 percentage point on average through the first three quarters of 2008, before contributing 1.7 percentage points in the fourth quarter as prices plummeted.     

Economic and political risks of world oil markets

The present easing on the world oil market could foster the illusion that energy problems are now resolved. During 1981 various oil-producing countries (OPEC and non-OPEC alike) found they had to cut their prices. OPEC production has had to be reduced by about one-third from the 1979 level of 31 mbd¹. Last September’s OPEC output of 20 mbd was the lowest monthly figure for 12 years and has by year-end 1981 recovered to just 22 mbd. “The OPEC is no longer able to dictate prices; there is more oil than the market can take.” These are typical recent comments, but they reflect too short-term and superficial a view. The real issue is the question whether energy supplies are secure in thelong term, too, and whether energy itself presents a danger for general economic and political developments.     

Oil Market at a Turning Point?

Crude oil prices have fallen markedly during recent months, so much so that the OPEC countries finally took action and resolved to curb production levels. Is the oil market becoming accustomed to ongoing geopolitical risks, and are oil price developments now being more strongly determined by fundamental market data once again?     

Do inpayments and outpayments respond to exchange rate changes asymmetrically: Evidence from Malaysia

Since the pass-through of exchange rate changes on import and export prices are asymmetric, we expect a country’s inpayments (export earnings) and outpayments (cost of imports) to also react to exchange rate changes asymmetrically. We demonstrate this hypothesis by considering trade between Malaysia and each of her 11 largest trading partners. We find that while the short-run effects of exchange rate changes on Malaysia’s inpayments and outpayments are asymmetric with all partners, the long-run asymmetric effects are present in less than half of the partners. The results are partner specific.     

Transmission of external price disturbances and the composition of trade

This paper focuses on the role of trade composition in the transmission of external price disturbances. It is shown that the effects of an increase in the price of imports on domestic prices and the trade balance crucially depend on the cross price elasticity of demand in the case of final goods and the elasticity of substitution between factors in the case of intermediate goods. In the case of an input such as oil, where the elasticity of substitution between imported and domestic factors of production is less than unity, an increase in its price will give rise to a balance-of-trade deficit but will have ambiguous effects on domestic prices.     

Modelling the asymmetric responses of price level to oil price changes in Qatar

This paper inspects the asymmetric effect of oil price on prices level in Qatar. To achieve that, we proceed by employing a nonlinear autoregressive distributed lag (ARDL) approach on data during the period 1990Q1–2014Q4. The estimation results show evidences of an incomplete and asymmetric influence of oil price on price level in the long term. Moreover, we find that price responses to negative changes in oil price is greater than its response to positive changes. Given Qatar’s economic features, a decrease in oil price could cause lower imports and production prices and consequently a substantial influence on domestic prices level. However, the lower effect of positive oil price changes on consumer prices can be explained by the subsidies system, the consumption patterns, and the exchange rate regime.     

Oil shocks and external adjustment

We examine the effects of endogenously determined oil price fluctuations in a two-country DSGE model. Under incomplete financial markets, an oil market-specific shock that boosts the oil price results in a wealth transfer toward oil exporters, depresses the oil importer's consumption, and causes the oil importer's real exchange rate to depreciate. Although the oil importer experiences a deterioration in the oil component of its trade balance, an improvement in the nonoil balance substantially dampens the effects on the overall trade balance.     

欧盟反倾销调查与中国对欧出口贸易间关系 研究：基于ARDL-ECM 模型的分析

欧盟对华反倾销问题是当前中欧经贸关系进程中的重大问题,本文采用ARDL模型和边界检验技术,实证分析欧盟对华反倾销与中国对欧出口之间的长、短期关系。结果显示,我国对欧出口与欧盟GDP、出口商品价格、反倾销之间存在协整关系。根据协整分析,长期内欧盟对华反倾销并未抑制我国对欧出口贸易,相反,反倾销在一定程度上推动了对欧出口规模;欧盟成员国收入水平对出口贸易有较大的促进作用;出口价格变动对出口抑制效应不明显。     

The foreign trade of the OPEC states

The changes brought about in the OPEC states by their oil are reflected most clearly in the foreign trade¹. How did their trade develop during the present decade? What will be the outcome of the latest drastic oil price increases?     

人民币汇率变动与中国的贸易收支——基于汇率传递视角的实证研究

文章从汇率传递视角探讨了人民币名义有效汇率与贸易收支的关系。结论表明:首先,人民币汇率贬值和升值对贸易收支的影响存在非对称性,人民币升值对初级产品贸易收支、工业制成品贸易收支以及贸易总收支几乎没有影响;人民币贬值对工业制成品贸易收支和贸易总收支均存在显著性的影响,但对初级产品贸易收支没有影响。其次,人民币汇率变动对初级产品的净出口基本没有影响,其主要原因在于中国对金属矿砂、煤、焦炭、石油等主要初级产品的刚性需求以及中国在国际市场上对稀缺资源性产品定价权的缺失与不足。再次,人民币贬值不仅不能增加工业制成品净出口,反而恶化了工业制成品的贸易收支,究其原因,在于占较大比重的机械及运输设备类产品的进出口需求弹性较小。最后,本文在以上结论研究基础之上得到了许多有益启示。     

Foreign exchange rate and trade balance dynamics in East African countries

This study investigates the effects of real exchange rate on trade balance in East African countries. In contrast to past studies that have often focused on one country in the region and adopted traditional empirical methods that are subject to shortcomings, the present study employed the ARDL procedure and investigated the issue in 10 East African countries. The main results are as follows. First, real exchange depreciation significantly improves trade balance for four countries in individual country estimations, as well as in panel estimation. Second, the elasticity of trade balance with respect to real exchange rate is inelastic. Elasticity slightly increases after exchange rate liberalization but remains inelastic. Third, significant short-run fall was not found for trade balance, which suggests lack of evidence for J-curve relationship     

International trade in oil: Effects on the balance of payments and exchange rates

Oil price increases and the persistent OPEC current account surpluses were considered the main problems of economic development in many industrial and developing countries long after the first oil crisis. Since 1983, however, the OPEC surpluses have been completely absorbed and the official base price of petroleum has fallen for the first time in twenty years, although admittedly in terms of a “strong” dollar. Has the serious damage suffered by oil-importing countries in the two oil shocks been completely neutralised, or are the economies of many countries still strongly influenced by the actions and decisions of the OPEC countries?     

Musings on the Macroeconomic Effects of Oil Price Increases

In considering the macroeconomic effects of oil price increases, it is important to be mindful of whether changes come from the supply or demand side and whether they are accompanied by impacts on financial markets. Also, it is important to know whether a change is likely to be temporary or permanent and whether it can be offset by policy responses. Finally, the short-run effects of oil price changes are likely to be different from the long-run effects. This paper explores these questions and their ramifications for macroeconomic growth.     

Stock prices and exchange rate dynamics in Nigeria: An asymmetric perspective

This paper investigates the asymmetric effect of exchange rate changes on stock prices in Nigeria. Using the nonlinear ARDL framework and monthly data from 2000:1 to 2016:12, the nominal exchange rate is separated into currency depreciation and appreciation through a partial sum decomposition process. Asymmetry is examined both in the long-run relationship and short-run error correction mechanism. The results show that the effects of exchange rate changes on stock prices is asymmetric both in the short- and long-run. That is, stock prices react in different magnitude to depreciation and appreciation. However, currency depreciation has a strong pass-through effect on stock prices than appreciation in the long-run. In the absence of asymmetry, exchange rate has only short-run effect on stock prices. This implies that the symmetry assumption underestimates the impact of exchange rate changes on stock prices in Nigeria.     

Real Exchange Rates and ASEAN Trade

This paper systematically analyses the longer-term effects on the Association of South-East Asian Nations (ASEAN) trade of changes in competitiveness brought about by changing real exchange rates. We introduce a model to explain exports from four ASEAN countries which highlights the role of real exchange rates. Specifically, we provide evidence on the price responsiveness of export demand. The results indicate that (i) there have been large changes in real exchange rates; and (ii) the pattern of ASEAN trade responds to relative prices (real exchange rates). Suprisingly, however, the impact of observed changes in real exchange rates on ASEAN trade is only relatively minor.
