Free riders and the redistributive effects of international commodity agreements: The Case of Coffeee

Most studies on the redistributive effects of international commodity agreements neglect the existence of free riders. This article shows, however, that incentives for a free rider behavior may exist under various systems of commodity control. The International Coffee Agreement includes an export quota scheme that is faced with free riders on the import side. The factors that determine the impacts of such a scheme on prices, trade, earnings, and expenditures on the world market and on welfare of importing nonmember countries are elaborated theoretically. An econometric model of the world coffee market is then used to measure the effects of coffee export quotas on different variables of the world market. By use of estimated national import demand functions for coffee, the national welfare gains of importing nonmember countries due to the quota policy of the International Coffee Agreement are also computed.     

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.     

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.     

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.     

The linkage effects of raw material processing in economic development: A survey of modeling and other approaches

Processing of primary raw materials has become an important and widely recommended strategy for economic development. Yet, even as the councils of many LDCs call for primary commodity producers to gain greater participation in downstream activities, there remain doubts on fundamental questions:What comparative advantage and what disadvantages do processing activities have in the LDCs?What linkages do processing activities offer?What is the potential contribution of processing to economic goal attainment in the LDCs?In this article we survey the material on processing, particularly with respect to modeling direct and indirect linkages between processing and the LDC economies. The article examines the following topics: (1) the literature on processing in economic development; (2) modeling processing linkages; and (3) outstanding questions regarding processing linkages.We focus on quantifiable linkages between the processing industry and the rest of the economy. There is also the possibility of other linkages, such as the development of entrepreneurship and management talent and technology, that are more difficult to quantify. It is important to distinguish between micro linkages, which refer to the direct impact on supplier and user sectors, and macro linkages, which include indirect general economic effects transmitted through government revenue and expenditures, the money supply, and foreign exchange availabilities.     

Macroeconomic stabilization of primary commodities price cycles in developing economies

This paper proposes a strategy for stabilizing macroeconomic policy to address jointly the effects of changes in the prices of food, minerals and energy (oil). Our approach differs from the general literature, which analyzes the effects of a commodity boom or bust and therefore the solutions in terms of economic policy separately, that is, by type of commodity. The stabilization strategy that we propose considers a key fact affecting many open economies, namely, that they not only are affected by increases or decreases in commodity prices, but also benefit from them. Consequently, we use a structural model for an open economy with restricted households to show that welfare could be improved with a fiscal rule incorporating transfers to stabilize household consumption. This strategy noticeably dominates an aggressive monetary policy focused only on stabilizing inflation and a fiscal policy that has an excessive bias toward saving income from exports.     

Can Latin America carry its international debt? A prospective analysis using the Wharton Latin American debt simulation model

The international debt of the LDCs has become a critical concern, perhaps currently the most critical one, from the perspective of debtor countries and creditors alike. Through the efforts of the IMF, the BIS, the central banks, and the large commercial banks, a crash may have averted for the time being, but the heavy burden of the debt remains, particularly in Latin America, where it is increasingly concentrated. Draconian remedial measures now threaten social and economic development throughout the continent.This article evaluates the perspective for Latin American debts and payments using a debt simulation model. Debt restructuring with the usual “IMF conditions” will impose serious economic shocks in Latin America. But even so, debt service ratios will remain high except under optimistic assumptions about growth in the industrial countries and about commodity prices. Only in case of a solid economic recovery in the United States, Europe and Japan can one be sanguine about Latin America's ability to work its way out from under the debt burden.     

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.     

Short run responses to foreign exchange crises

This paper constructs a short-run general equilibrium model for an LDC-type economy. Some key features are the possibility of excess capacity and the presence of quantitative restrictions on exports and imports. A rich variety of pricing possibilities for tradeable goods is allowed for, including “water in the tariff” as well as domestic prices exceeding world prices with binding import quotas.The model is used to analyze alternative responses to a foreign-exchange crisis. Import controls, devaluation and cuts in government expenditures are compared. We find that: i) import quotas can worsen the balance of trade, ii) rationing foreign exchange for noncompetitive imports is stagflationary, increasing prices even under excess capacity, iii) a devaluation has strong effects on income distribution, although output and employment expand, and iv) cuts in government spending are deflationary but the income distribution effects are neutral.     

The impact of social heterogeneity and commodity price shocks on civil conflicts

Do exogenous economic shocks promote civil conflicts directly? Do they affect all the societies alike? The current approach presents a large sample panel data evidence not only on the effect of commodity export price shocks on conflict incidence, rather than onsets, but also on the joint impact of both ethnic and religious polarization and fractionalization on political instability. In this regard, we find out that in ethnically polarized societies, the commodity export price shocks increase violence. Nonetheless, in ethnically and religiously fractionalized societies (as well as religiously polarized), the effect of commodity export price shocks on civil conflicts depends on the type of income shocks and category of commodity. These findings contribute to the existing literature by illuminating the compound effect of both income shocks and social diversity on intrastate conflicts.     

On Primary Commodity Prices: The Impact of Macroeconomic/Monetary Shocks

The hypothesis of a long-run quantifiable relationship between non-oil primary commodity prices and macroeconomic/monetary variables—focusing industrial production and effective exchange rate of the US dollar—is tested by cointegration technique using quarterly data for 1970q2–93q3. This confirmed equilibrium adjustment explains the origin of the observed coincidence of commodity price variations with the fluctuations of macroeconomic/monetary variables. An error correction specification, including interest rate, is therefore applied to estimate the observed disequilibrium prices of commodities in the context of steady-state solutions. This instantaneous adjustment explains why commodity prices have fluctuated more strongly over the last 2 decades than before.     

Modeling manufactured imports: Methodological issues with evidence from Australia

This paper investigates the relationship between manufactured import flow to Australia, and relative prices and domestic economic activity net of cyclical demand effects over the period 1981Q3 to 1991Q2. This is done through the estimation of import demand functions for total manufactured imports and nine major import categories using the general-to-specific modeling approach. We find that the homotheticity assumption on activity elasticity is met in most cases. The price elasticity estimates for individual categories range from 0.32 to 2.1, with a weighted average of 0.52. We also find some evidence of upward bias in price elasticity estimates when an aggregate import function is employed in a context where a significant portion of imports are subject to quantitative restrictions (QRs).     

The relationship between conflict events and commodity prices in Sudan

Though recent literature uncovers linkages between commodity prices and conflict, the causal direction of the relationship remains ambiguous. We attempt to contribute to this strand of research by studying the dynamic relationship of commodity prices and the onsets of conflict events in Sudan. Using monthly data ranging from January 2001 through December 2012, we identify a structural breakpoint in the multivariate time series model of prices of the three staple foods (sorghum, millet, and wheat) and conflict measure (number of conflict events) in September of 2011. Applying structural vector autoregression (SVAR) and linear non-Gaussian acyclic model (LiNGAM), we find that wheat price fluctuation is a root cause of conflict events in Sudan. We recommend several policy and programmatic suggestions structured toward production, subsidy, price regulation and support for rural farmers and consumers to stabilize commodity prices.     

Automobile prices and protection: The U.S.-Japan trade restraint

We examine the effects of the U.S.-Japan trade restraint on automobile prices and quality upgrading, for both Japanese imports and American small cars. From April 1981 to April 1984 the suggested retail price of all Japanese models increased by 15.8 percent, or 5.3 percent per year. We find that nearly the entire amount of this rise can be explained by the upgrading of individual models. This upgrading may benefit consumers who would purchase a luxury import in any case, but harms those who desire the basic imports. In addition to upgrading, we conclude that a second cost of the trade restraint has been to prevent the yen depreciation from being passed onto American consumers, in terms of lower imported auto prices. For U.S. small cars we find a 9.1 percent rise in the suggested retail price, or 3 percent per year, with a fraction of this amount due to model upgrading. If the yen depreciation had led to lower import prices without the trade restraint, then we expect that U.S. auto prices would have been lower, too.     

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.

Policy Simulation of the Indian Silk Industry through an Econometric Model

This study aimed at understanding and quantifying the relationship between the important variables of the various subsectors of the Indian silk industry through an econometric simulation model, and using the model for forecasting as well as policy simulations. Forecasts of the endogenous variables of the system (demand, supply, and prices of mulberry cocoons, raw silk, and silk fabric) for the period 1991–92 to 2000–01 indicates that the growth in the industry will slow down in the future. Policy simulations were undertaken to assess the changes in the import price of raw silk, export price of fabrics, and regulation of the quantity of imports of raw silk on the silk industry. While imports and exports were closely linked, their impact on the silk industry was not very high. It was also revealed that the income of the consumers and mulberry acreage have significant influence on the industry.     

Price vs. revenue stabilization through a buffer stock: Which is more financially feasible for LDCs?

Optimal control theory is used to analyze the implications of the adoption of price and LDC export revenue stabilization objectives by an international buffer stock for cocoa. The results obtained for the period 1956–76 suggest that the stabilization of either price or revenue at systematic trend would reduce the instability of both variables from that during the sample period. Although the stabilization of revenues at systematic trend decreases their average level, the stabilization of price has the opposite effect. Because of this, it may be financially feasible for the LDCs to provide the necessary resources for a price-stabilizing buffer stock.     

The cost of war: Impact of sanctions on Russia following the invasion of Ukraine

We use a computable general equilibrium model of world trade to quantify the possible impact of economic sanctions imposed by Western and other countries in response to Russia’s invasion of Ukraine. If sender countries chose 100 % import tariffs and export taxes on trade with Russia, Russia’s GDP would decline by 3–7 % due to the resulting significant reduction in exports. By contrast, the GDP loss for those countries would be 0.2 % for the European economies, but only about 0.05 % for Japan. Although unlikely, the effect of China’s participation in the sanctions would be more significant than that of India. There are concerns about food and energy crises due to economic sanctions against Russia, but the effect on food supplies would not be a serious problem for either senders or third parties. The impact on energy supplies would affect all senders to some extent; for example, there would be a 3% reduction of energy consumption and a 3–4 % rise in electricity and town gas prices in Japan.     

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.
