Unfair Trade? The Increasing Gap between World and Domestic Prices in Commodity Markets during the Past 25 Years

The early literature on international trade has debated extensivelythe constraints facing exporting countries in the major commoditymarkets. This article goes one step further by suggesting thatthe final demand for these products could not have increasedbecause the declines in world commodity prices were not transmittedor were transmitted imperfectly to domestic consumer prices.In contrast, upward movements in world prices were clearly passedon to domestic prices. As a result, the spread between worldand domestic prices almost doubled in all major commodity marketsduring 1975–94. This asymmetry, seldom discussed in theliterature, does not seem to be caused, at least systematically,by changes in trade and tax policies or factors such as transport,processing, and marketing costs. This article argues, therefore,that a special effort should be made to better understand thetransmission from world to domestic prices, especially the roleof large international trading companies that may have the capabilityto influence such spreads through one or several stages of processingin most major commodity markets.     

A New Method for Estimating the Effects of Fuel Taxes: An Application to Thailand

This article proposes a new methodology for estimating the impactof fuel price and tax changes on the general price level andthe distribution of income and applies a model to Thailand usingdata for 1975–76 and 1981–82. Because the modelallows for pricing under international competition where taxincreases must be partially absorbed in reduced factor incomerather than always being passed on in higher consumer prices,the results are significantly different from those generatedby the more conventional cost-plus pricing rule. The inflationaryimpact of fuel tax changes is slight because of both the opennessof the economy and the low energy intensity of manufacturingand other production in Thailand. In contrast, taxes on importsengender price increases not only for imports but also for goodswhich substitute for imports. The model also indicates thatthe net effects of taxes on petroleum products (other than kerosene)are progressive in their distributional impact, relative toa tax on imports or consumption. A main policy conclusion ofthe study is that fuel taxes could be used to increase bothequity and allocative efficiency without inducing significantinflationary responses. It follows that in the current circumstancesof falling world oil prices, developing countries could generaterevenues needed for structural adjustment by increasing fueltaxes to maintain domestic petroleum price levels.     

A SURVEY OF THE COSTS OF WORLD SUGAR POLICIES

The world sugar market has long been characterized by volatileprices and widespread intervention. Controls on domestic prices,demand, and supply have created an inefficient pattern of worldproduction, consumption, and trade. Without government controls,production would shift from the countries with higher cost,subsidized production (especially the European Community, Japan,and the United States) to the countries with lower costs (suchas Australia, Brazil, and Thailand). The resources saved couldthen be directed to other activities. Sugar policies in countries with high costs reduce world sugarprices quite substantially in the long run and increase pricevariability significantly; production controls in countrieswith low costs increase world prices somewhat and also increasetheir variability. What would happen if all interventions ceased? Average worldsugar prices would probably— but not definitely—rise. World prices would definitely vary less, and economicconditions would definitely improve, especially in developingcountries that depend heavily on sugar exports. But the prospectsfor substantial reform of the sugar market are not promising,even though the GATT Uruguay Round continues. This article putsforward some modest proposals for changing the existing interventionsto lessen economic distortions and reduce costs.      

Oil prices and transport sector returns: an international analysis

This study examines the role of oil prices in explaining ‘transport sector’ equity returns in 38 countries across the world. The findings of the study are strongly supportive of some role for oil prices in determining the transport sector returns for the countries falling within the ‘Developed’, ‘Europe’ and ‘G7’ groupings. In particular, by allowing for an asymmetry in our model, we find the oil factor to be jointly significant along with the presence of negative oil risk premium in these groupings. It is worth noting that these groups represent mature economies and stock markets. However, there appears to be no such evidence of a significant role for oil for other country groupings (named, Asia Pacific, Emerging and Latin America). Collectively these countries have a relatively short market history and/or are developing economies.     

Imports under a Foreign Exchange Constraint

To assess proposed macroeconomic adjustment programs, policymakersmust estimate import demand relative to the foreign exchangeavailable. Traditional models estimate import demand as a functionof relative prices (the real exchange rate) and income (grossdomestic product) but omit changes in foreign exchange. In the1980s, however, declines in foreign lending and the terms oftrade and increased debt service costs reduced foreign exchangeavailability in most developing countries and limited importcapacity. In this article two import models are presented which incorporateboth the traditional variables and indicators of import capacity—foreignexchange inflows and international reserves. The first modelassumes that import prices are exogenous, but in the secondmodel import prices are endogenous—allowing for governmentattempts to reduce import demand by increasing the domesticimport price. The models are estimated using data for twenty-onedeveloping countries for 1970–83. The results suggestthat the import model presented here does a better job of explainingimport behavior than do the traditional model (which excludeschanges in foreign exchange) and the Hemphill model (which excludesrelative import prices and income).     

Do African Countries Pay More for Imports? Yes

The debt crisis and declining living standards require carefulhusbanding of critically scarce foreign exchange in most Africancountries. But economic theory suggests that smaller countries,which import from only a few international suppliers and cannotsupport competitive markets and infrastructure, would be likelyto pay more rather than less for imports. Analysis of importunit values for 1962–87 shows that the twenty Africanformer French colonies paid a price premium of 20–30 percenton average over other importers for iron and steel imports fromFrance. The losses associated with these adverse prices totaledapproximately 2 billion dollars by 1987. The study also findsthat similar price premia (of 20–30 percent) were paidby former Belgian, British, and Portuguese colonies in Africafor imports of these products from their former rulers.     

THE COMMON AGRICULTURAL POLICY: A Review of Its Operation and Effects on Developing Countries

Policy changes in the European Community (EC)—the world'slargest importer and, since 1986, exporter of agricultural commodities—mayhave significant effects on world markets and developing countries.This article investigates the EC's Common Agricultural Policy(CAP), its history, mode of operation, and the prospects andpossibilities for change, to bring out the implications of thepolicy for developing country exporters and importers. The hypothesisthat evolves differs from that of many studies in proposingthat an agricultural liberalization in the EC is unlikely toeffect any great change in world market prices over the firstfew years. Developing countries' principal gain from a liberalizationof the CAP would derive from increased stability of world marketprices, improved access to export markets, and a reduction inthe uncertainty currently caused by discretionary measures inthe EC.      

Capital Flows to Developing Countries: Long- and Short-Term Determinants

This article focuses on the determinants of the large portfolioflows from the United States to Latin American and Asian countriesduring 1988–92. Cointegration techniques reveal that bothdomestic and global factors explain bond and equity flows todeveloping countries and represent significant long-run determinantsof portfolio flows. The article also investigates the dynamicsof portfolio flows by estimating seemingly unrelated error-correctionmodels. Global and country-specific factors are equally importantin determining the long-run movements in equity flows for bothAsian and Latin American countries, while global factors aremuch more important than domestic factors in explaining thedynamics of bond flows. U.S. interest rates are a particularlyimportant determinant of the short-run dynamics of portfolio,especially bond, flows to developing countries.     

Determinants of Commercial Bank Interest Margins and Profitability: Some International Evidence

Using bank-level data for 80 countries in the years 1988–95,this article shows that differences in interest margins andbank profitability reflect a variety of determinants: bank characteristics,macroeconomic conditions, explicit and implicit bank taxation,deposit insurance regulation, overall financial structure, andunderlying legal and institutional indicators. A larger ratioof bank assets to gross domestic product and a lower marketconcentration ratio lead to lower margins and profits, controllingfor differences in bank activity, leverage, and the macroeconomicenvironment. Foreign banks have higher margins and profits thandomestic banks in developing countries, while the opposite holdsin industrial countries. Also, there is evidence that the corporatetax burden is fully passed onto bank customers, while higherreserve requirements are not, especially in developing countries.     

Implications of domestic price insulation for global food price behavior

Rapid changes in global food prices in recent years are widely viewed as a serious threat to global development. While various sources of price instability in agriculture have been identified, little attention appears to have been given to the importance of changes in trade policies that insulate domestic prices from world markets as a source of volatility in world prices. A contribution of this paper is to show that these interventions are dynamically more complex than simple proportional insulation. Insulation against an initial price increase in world prices increases the magnitude of that increase, while subsequent adjustments to the level of protection change the fundamental nature of price volatility. We find such policies are widespread and increase the volatility of world prices while not reducing the volatility of domestic prices because of the collective action problem involved in this form of policy intervention.     

Asset Prices,News Shocks,and the Trade Balance

We analyze the relationship between asset prices and the trade balance estimating a Bayesian VAR for a broad set of 38 industrialized and emerging market countries. To derive model‐based identifying restrictions, we model asset price shocks as news shocks about future productivity in a two‐country dynamic stochastic general equilibrium model. Such shocks are found to exert sizable effects on the trade balance. Moreover, the effects are highly heterogeneous across countries. For instance, following a news shock that implies on impact a 10% increase in domestic equity prices relative to the rest of the world, the U.S. trade balance will worsen by up to 1.0 percentage points, but much less so for most other economies. We find that this heterogeneity appears to be linked to the financial market depth and equity home bias of countries. Moreover, the channels via wealth effects and via the real exchange rate are important for understanding the heterogeneity in the transmission.     

A Cross-Country Database for Sector Investment and Capital

This article presents a new database of investment and capitalin agriculture, manufacturing, and the overall economy. It covers62 industrial and developing countries for the years 1967–92.A common method is used in the calculations to facilitate comparisonsacross countries and sectors. The sensitivity of the calculationsto choices of parameters and estimation methods is tested. Collectively,the data show that as economies grow, capital stocks accumulate,but the composition of capital changes. Together and individually,capital stocks in agriculture and manufacturing constitute asmaller share of the total capital stock than they did 20 yearsago. Capital-labor ratios show that agriculture has become morecapital intensive in most countries. The composition of agriculturalcapital has changed as well; capital from investments in orchardsand livestock has declined relative to capital from fixed investmentsin machinery, irrigation, and buildings.     

Macroeconomic Shocks and Banks' Foreign Assets

Recent developments in international financial markets have highlighted the role of banks in the transmission of shocks across borders. We employ dynamic panel methods for a sample of OECD countries to analyze whether banks' foreign assets react to macroeconomic shocks at home and abroad. We find that banks reduce their foreign assets in response to a relative increase in domestic interest rates, and they increase their foreign assets when the growth rate of world energy prices rises. The responses are characterized by a temporal overshooting and a dynamic adjustment process that extends over several quarters.     

International capital market equilibrium with investment barriers

This paper outlines models of capital market equilibrium when there are explicit barriers to international investment in the form of a tax on holdings of assets in one country by residents of another country. There is a corresponding subsidy on short positions in foreign assets. Asset prices deviate from the predictions of the world capital asset pricing model. Investors do not hold a mixture of national market portfolios, but the mix of risky assets is the same for every investor in a country. Optimal portfolios tend to be heavy in domestic assets, and light in foreign assets. Tax free investors, however, tend to hold assets anywhere in the world that are taxed heavily. Estimates of the magnitude of the average tax (or the magnitude of effective barriers to international investment) can be made by comparing the average return on the minimum variance zero β portfolio, z, with the average across countries and time of the short-term interest rate. When barriers are ineffective, the expected return on portfolio z will be the average short-term interest rate, and the world capital asset pricing model will hold.     

Doha Merchandise Trade Reform: What Is at Stake for Developing Countries?

The LINKAGE model of the global economy and the latest GlobalTrade Analysis Project (GTAP) database (version 6.05) are usedto examine the impact of current merchandise trade barriersand agricultural subsidies and possible reform outcomes of theWorld Trade Organization’s (WTO’s) Doha DevelopmentAgenda. The results suggest that moving to free global merchandisetrade would boost real incomes in Sub-Saharan Africa proportionatelymore than in other developing countries or in high-income countries,despite the terms of trade loss in parts of that region. Particularattention is given to agriculture, as farmers constitute thepoorest households in developing countries but the most assistedin rich countries. Net farm incomes would rise substantiallyin Sub-Saharan Africa and other developing country regions,alleviating rural poverty. Partial liberalization could movethe world some way toward those desirable outcomes, the moreso the more developing countries themselves cut applied tariffs,particularly on agricultural imports.     

Domestic macroeconomic determinants of precious metals prices in developed and emerging economies: An international analysis of the long and short run

This study examines the relationship between domestic macroeconomic factors and domestic precious metals prices across developed and emerging markets from 1979 to 2020. The statistical characteristics of the domestic variables are not found to be consistent across countries, so that these relationships cannot be modelled in one specific way. To model each metal domestically, we use various time series techniques as dictated by the combined characteristics of the domestic variables.The findings of this analysis reveal relationships that are not consistent across countries or precious metals. No consistent set of variables is found to exist that can explain either the short or the long run determinants of domestic precious metals prices, and there is no clear divide between developed or emerging markets. Any model of the determinants of a precious metal's domestic price requires individual handling by the practitioners or academics undertaking it, rather than assuming a single set of determinants as is frequently done.     

The determinants of secondary market prices for developing country loans: the impact of country risk

With better-defined variables based on Euromoney country risk data as explanatory variables, the determinants of the prices of the debts of less-developed countries (LDCs) in the secondary market are estimated. With the use of cross-sectional data on 27 countries for the years 1992, 1993, and 1994, the regression results indicate that sovereign credit ratings constitute the most important variable influencing prices; other significant variables include the level of external indebtedness and the amount of debt in default. Separate results have been obtained for each of the two categories of countries grouped according to the level of economic development. These results are more meaningful than those of previous studies because the model includes, in addition to debt-servicing capacity, other variables that best explain the prices of LDCs' debt within the context of a risky debt instrument.     

The Great Recession: US dynamics and spillovers to the world economy

This paper provides an empirical investigation of both the within-US and international channels of transmission of macroeconomic and financial shocks by means of a 50-country macroeconometric model (estimated over the 1980-2009 period), including measures of excess liquidity and financial fragility, specifically designed in order to evaluate the relevance of the boom-bust credit cycle view put forward as an interpretation of the recent “Great Recession” episode. We find that such a view is consistent with the empirical evidence. Moreover, concerning the real effects of financial shocks within the US, we detect stronger evidence of an asset prices channel, rather than a liquidity channel. Concerning the spillovers to the world economy, we find that while financial disturbances are transmitted to foreign countries through US house and stock price dynamics, as well as excess liquidity creation, the trade channel is the key trasmission mechanism of real shocks.     

The World Price of Foreign Exchange Risk

Departures from purchasing power parity imply that different countries have different prices for goods when a common numeraire is used. Stochastic changes in exchange rates are associated with changes in these prices and constitute additional sources of risk in asset pricing models. This article investigates whether exchange rate risks are priced in international asset markets using a conditional approach that allows for time variation in the rewards for exchange rate risk. The results for equities and currencies of the world's four largest equity markets support the existence of foreign exchange risk premia.
