Commodity price shocks and the distribution of income in commodity-dependent least-developed countries

Many least developed countries (LDCs) face commodity dependence on the export and import side. This paper develops a structuralist computable general equilibrium model for commodity-dependent LDCs and simulates global commodity price shocks for Burkina Faso, Ethiopia and Mozambique. Results show important macroeconomic and distributional effects. Although increasing export commodity prices are beneficial, the high correlation with import commodity prices causes low or even negative combined effects. The magnitude of effects depends on the degree of import and export dependence, the production structure of the key commodity sectors and policies that determine the distribution of windfall profits.     

Comments on Montague J. Lord's “distributional effects of international commodity price stabilization: Do the aggregate gains apply to individual producing countries?” [JPM 3:61–75 (1981)]

Lord discusses the impact of international commodity price stabilization on Latin American producing country export revenues. He correctly emphasizes that the directions and magnitudes of such effects may vary substantially across producers, depending on the degree of segmentation of the commodity markets and the nature and distribution of the shocks. However his potential contribution may be lost because of a number of inaccuracies, which I discuss under three general topics.     

International transmission of monetary and global commodity price shocks to Turkey

This paper explores the international transmission mechanisms on the macroeconomic and monetary variables of Turkey and hence proposes some particular policy implications. The effects of monetary shocks stemming from the U.S. and the European area, and global commodity price shocks are investigated using a structural vector auto-regression (SVAR) approach. For the analysis, we use monthly data from 2002M01 to 2016M06 and we analyze the transmission mechanism in Turkey using two different SVAR model specifications. Our results reveal that shocks coming from the U.S. and the Euro area lead to significantly different responses on industrial production, consumer prices, real effective exchange rates, and the domestic interest rate, with the Euro area monetary expansion having more explicit and positive effects on the real economy. The global commodity price shocks affect the Turkish macroeconomic variables in a similar but much less powerful fashion than that of the U.S. monetary expansion. As our empirical findings point out that the Turkish economy is vulnerable to global monetary and commodity price shocks. This vulnerability necessitates moving to a sustainable growth path consistent with a sustainable current account balance and a sustainable private and government debt coupled with a strengthened macroprudential regime and comprehensive structural reforms.     

Commodity buffer stock redux: The role of International Cocoa Organization in prices and incomes

This paper utilizes linear demand and supply models, with additive independent shocks, to derive producer price and income variances of a typical commodity during and after a buffer stock control. It proceeds to use the models to evaluate International Cocoa Organization's (ICCO) Buffer Stock's decision to purchase excess stock from the market a floor price and re-sell it, in periods of low supply, at the ceiling price. The results show that cocoa producer prices and incomes were more stable during periods of ICCO buffer stock intervention than after the demise of the buffer stock. The results further indicate that stock-buying operations induced greater stability in producer incomes than buying stock-selling operations.     

Commodities and monetary policy: Implications for inflation and price level targeting

We examine the relative ability of inflation targeting and price level targeting monetary policy rules to minimize inflation variability and business cycle fluctuations in a commodity-exporting country for supply and demand shocks to global commodity markets. The macroeconomic consequences of oil and non-oil primary commodities differ and affect the relative merits of the alternative monetary policy frameworks. Particularly, the consumption of refined oil products and demand-driven commodity price movements induce highly persistent inflation pressures resulting in a significant deterioration of the inflation-output gap trade-off available to central banks. When such terms-of-trade shocks are prevalent, price level targeting is inferior to inflation targeting.     

Trade sophistication in developing countries: Does export destination matter?

We investigate whether exports to developed economies stimulate export sophistication (represented by UNCTAD’s index of export similarity) in developing countries. Results from fixed-effects estimations suggest that exporting to developed economies enhances the sophistication of exports in the exporting country but there are diminishing returns to this effect. We also find non-linear effects from FDI and income on export sophistication with the effect of income exhibiting diminishing returns which suggests that the gains from exporting to developed economies are higher for lower-income countries; i.e., as income increases, the gains taper off. We discuss the policy implications of these results.     

Commodity prices and the world distribution of income

Some advocates of a new international economic order recommend raising prices of commodities exported by developing countries as a means of reducing the inequality of world income distribution. A simulation model using commodity trade data and income distribution data for 68 industrial and developing countries examines this policy alternative. Initial data compilation reveals that internal inequality is as important as international: The world income share of the poorest 40% of people would be twice as high in the absence of intracountry inequality. Calculations using actual price experience in the “great inflation” of 1972–1975 show that despite the large relative price changes for some commodities (especially oil), these changes left the world size distribution of income virtually unchanged. Separate policy simulations show that even a quadrupling of the price of ali “equalizing” commodities (those mainly exported by LDCs) would leave the size distribution of world income practically unaltered (even under optimistic assumptions about intracountry distributional incidence), although some individual LDCs would gain. Increasing commodity prices therefore appears to be an ineffective means of increasing international equity, quite apart from questions about the feasibility of cartels or commodity agreements.     

Must high commodity prices depress the world economy? An application of a world model system

The impact of higher primary commodity prices on the world economy is central to the North-South dialogue. The less developed countries are seeking a way to obtain a larger share of world income. In the context of current discussions of commodity price stabilization, UNCTAD's “integrated programme” for example, this is likely to mean higher commodity prices. A critical question is then, “Must higher prices for primary commodities depress the industrial economies?”The cyclical swing of 1973–1975 would seem to support the thesis that high primary commodity prices lead to recession in the industrial countries. Yet this experience is not conclusive evidence. Many complex forces, some natural and others policy induced, accounted for the recession. The impact of primary commodity prices must be considered in a full system, recognizing not only the direct costs, but also the resulting demand feedback. Under different circumstances, higher payments to the commodity producing LDCs may well increase demand for manufactures and stimulate exports and industrial activity in the developed countries.This paper uses a version of the LINK world model system to examine the linkages between commodity prices and world economic activity. In the first part we examine the demand feedback in a simple theoretical model of the interrelationships between commodity consumer countries and the commodity producers. In the second part we use an empirical system, COMLINK, the version of the LINK system that incorporates commodity models and commodity price linkages, to simulate various types of commodity price impacts.     

Policy responses to external shocks in sub-Saharan African countries

The author analyzes the experience of sub-Saharan African countries with external shocks in the form of the deterioration of the terms of trade and the world recession between 1973 and 1978, with distinction made between low-income and middle-income countries. Adjustment to external shocks in low-income sub-Saharan African countries took largely the form of reductions in imports through lower rates of economic growth and lower income elasticity of import demand while these countries lost export market shares. Losses in export market shares were smaller in the middle-income countries and in the entire group, export performance was positively correlated with the rate of economic growth.     

The impact of India’s food security policy on domestic and international rice market

Food security policy making in India is at crossroads. India has emerged as a leading rice exporter. The Government of India has introduced the National Food Security Act which requires 33.6 million tons of rice per year for its public food distribution system. In this study, we modeled India’s rice market and analyzed policy implications of the long-term impact of India’s food security act on domestic and international rice market. We developed a structural economic demand and supply model for India’s rice market and further added subsidy equations to trace the consequence of National Food Security Act on domestic rice consumption and on the international market. We specifically focus on three different scenarios: subsidy as price effect, subsidy as inelastic income effect, and subsidy as elastic income effect under the broader framework of National Food Security Act. We found that at the end of the projection period (2024–2025), as a result of rice subsidy program, the consumption of rice increases significantly in the case of price effect while the inelastic income effect has no or less impact on production, consumption, and export of rice. Hence, the policy implication of our study is that if the objective of the National Food Security Act is to increase consumption then it needs to be implemented as price effect.     

Alternate adjustments to external shocks in Hungary

A multisector computable general equilibrium model is used to evaluate Hungary's response to the external price shocks in the 1970s. The model incorporates characteristics of Hungary's reformed socialist economy. The results show that although the deterioration in terms of trade was important, the policies of insulation of the economy and increases in investment had a much larger detrimental impact on the trade balance. The existence of planned CMEA trade reduced the effects of the price shocks on the trade deficit. Export promotion by means of higher export subsidies would not have been effective to reduce the trade deficit in Hungary.     

Effects of export diversification in a primary commodity export country: Colombia

This article examines the income and allocation effects of an appropriate export diversification policy by means of a computable general equilibrium model for Colombia. This kind of policy is often envisaged to reduce the dependence of developing countries on primary commodity exports, which are considered to be a source of economic instability. The results show that an appropriate diversification of exports has positive income effects in Colombia.     

Measuring the economic impacts of recent oil price shocks on oil-dependent economy: evidence from Malaysia

This paper examines the economy-wide impacts of recent oil price shocks on the Malaysian economy. To achieve this objective, an integrated methodological framework that combines econometric and input–output models is utilized to assess the impacts of an oil price shock on tax revenues, employment, labor income and gross domestic product (GDP). Our results reveal that the recent oil price shocks significantly affects these macroeconomic variables. The decline in oil prices from 2015 to 2016 reduces tax revenues by 10.5%, lower GDP by 1.9% and increases the unemployment rate by 0.3%. As such, the sharp crunch in oil prices serves as a reminder to policymakers on the vulnerability inherent in overreliance on oil exports and the urgent need to diversify the economy.     

A model of price and quantity adjustments in primary commodity markets

This paper presents a dynamic, simultaneous model of price and quantity adjustments in world primary commodity markets. The model is formulated in a disequilibrium framework, emphasizing particularly the role of price adjustment. In addition to the price equation, commodity consumption and production equations are also specified. The empirical analysis of the model is carried out with the annual data of six primary commodities: coffee, cocoa, rubber, copper, tin, and sugar. This includes the estimation of price, consumption, production equations, the simulation tests of complete structural models for these six commodities, and the derivation of dynamic responses (measured by elasticities) of commodity prices to changes in world income, world inflation, and commodity outputs. Dynamic simulations strongly confirm the commonly observed self-generating and recurring boom-and-bust cycles of primary commodity prices. This finding lends credibility to the models constructed.     

Macroeconomic impact of public debt and foreign aid in Sri Lanka

Accumulation of public debt in Sri Lanka is raised significantly since the independence. It exceeded 100% of gross domestic products (GDP) in the late 1980s and the early 2000s. Although it has been declined in the recent past and becomes 79.3% of GDP in 2016; the high level of debt in a weak fiscal position of the small economy Sri Lanka is an issue of concern. In this backdrop, this paper examines the impact of public debt and foreign aid on income, price level and interest rate in Sri Lanka for the post-reform period. It is found that public debt in general and foreign debt, in particular, depresses income and stimulates price level. Domestic debt has some impact on the price level. On the other hand, foreign aid has a deleterious effect on both the income and price level. The foreign debt and aid have raised interest rate both in the short-run and in the long-run, while no significant impact of the domestic debt on interest rate is found. Based on these findings, the paper elaborates on some long-term measures for reducing the dependence on debt and aid in Sri Lanka.

Does country-risk influence electricity production worldwide?

This paper investigates the relationship between country-risks (or conflicts) within countries and electricity production. The determinants of electricity production have been neglected in the literature that favours the relationship between energy consumption, growth and development, and despite of the major challenges on electricity supply systems. We empirically establish that weighted conflict index, as well as sub-items as anti-government demonstrations, government crises and riots negatively influence electricity production per capita, after controlling for income per capita. Country conflicts affect electricity production mostly in the long-run. Our results imply that conflicts may affect electricity production substantially and consequently the economy as a whole. Policy should emphasize the institutional framework to avoid conflicts within countries in order to secure electricity production.     

论农业产业化向国际化迈进

农业产业化若局限国内市场,当各类农产品的供需达到均衡后,专业化、规模化生产就难以进一步增加农民的收入。农业产业化只有进一步向国际化迈进,充分利用自己的资源的优势,生产劳动密集型的农副产品,我国农民才能从扩大出口中增加收入。农产品在质量、安全、卫生以及口味、色泽等方面必须达到国际标准时,才能开拓国际市场,扩大出口,增加收入。     

出口退税率的调整对我国钢铁出口的影响分析

我国是钢铁生产大国、贸易大国,同时面临着高投入、高排放等诸多问题。“十一五”期间,国家采取了调整出口退税率等措施来限制“两高一资”产品的出口。回顾我国钢铁行业1994年以来出口退税率的调整变化,运用计量经济学模型,采用月度数据分析2004年-2010年出口退税率的调整对我国钢铁行业出口的影响。研究显示,出口退税率的调整对我国钢铁出口量存在微小的长期正向影响,短期作用效果不显著;国外需求因素对钢铁出口的刺激作用最突出,无论在长期或短期影响都非常显著;汇率、价格因素对钢铁出口的刺激作用其次,只存在长期均衡关系。     

The limits of inequality: Public support for social policy across rich democracies

Does public opinion react to inequality, and if so, how? The social harms caused by increasing inequality should cause public opinion to ramp up demand for social welfare protections. However, the public may react to inequality differently depending on institutional context. Using ISSP and WID data (1980?2006), we tested these claims. In liberal institutional contexts (mostly English‐speaking), increasing income inequality predicted higher support for state provision of social welfare. In coordinated and universalist contexts (mostly of Europe), increasing inequality predicted less support. Historically higher income concentration predicted less public support, providing an account of the large variation in inequality within the respective liberal and coordinated contexts. The results suggest opinions in liberal societies – especially with higher historical inequality – reached the limits of inequality, reacting negatively; whereas in coordinated/universalist societies – especially with lower historical inequality – opinions moved positively, as if desiring more inequality.
