THE IMPACT OF CHANGES IN TERMS OF TRADE ON A SYSTEM OF NATIONAL ACCOUNTS: AN ATTEMPTED SYNTHESIS*

The objective of this paper is to reformulate the terms of trade effect within a framework of national accounts in constant prices. The issue has been discussed by Professor R. C. Geary, Dr. G. Stuvel and others. In what follows the author proposes a new formula for deflating the net factor income from abroad and the net lending to the rest of the world. It is shown that the terms of trade effect which follows from the formula be expressed as a synthesis of Geary's and Stuvel's approaches. The author also shows that a similar approach be applied to the construction of the sector production account in constant prices. By formulating an appropriate deflator which is right for deflating factor incomes he concludes that the terms of trade arising from changes in inputs prices relative to output price be closely associated with the term which expresses the effect of productivity changes.     

EU-GCC free trade agreement: Adjustments in a factors proportion model for the UAE

The EU-GCC Free Trade Agreement would likely cause price changes across industries with subsequent effect on output and factor price adjustments. With higher levels of trade, the rising income will be redistributed among winner and loser industries and factors of production. This paper simulates the magnitude of these adjustments with a factors proportion model of production and trade for six different labor categories and capital in four sectors of the UAE economy. Results show a large impact on sector specific factors but for mobile factors, the shocks would be smaller suggesting a policy to increase factor mobility in the UAE.     

Trade,Wages, and Specific Factors*

In this paper, we use a multisector specific‐factors model with sector‐specific capital and two mobile factors, skilled and unskilled labor, to examine the effects of trade, technology, and factor endowments on the skill premium in US manufacturing industries. Based on this model and data for the US manufacturing sector from 1958–96, we calculate changes in the skill premium and then carry out a decomposition to identify the changes caused by product price changes (trade), technological progress, labor, and capital endowment changes. The decomposition reveals that trade effects, working through product price changes, caused the skill premium to increase moderately. Changes in capital endowments (new investments) had a positive effect on the skill premium, with the strongest impact during the 1980s, while the effect of technological change on the skill premium varied over time. Finally, changes in relative labor endowments had a negative effect on the skill premium.     

Offshoring and Trade Balance in Developed and Emerging Economies

This paper analyzes the effects of off‐shore outsourcing for international trade, especially for the emerging and poor economies, in a two‐sector specific factor model, with a nontraded good being one of the sectors. The phenomenon of offshoring is modeled by incorporating the reduced use of domestic labor in the production function. This is regarded as a characteristic feature of offshoring in the literature. We find that increased offshoring leads to an increase in the relative price of the nontraded good. Given that this relative price can be interpreted as the real exchange rate, increased offshoring leads to exchange rate appreciation. This suggests that offshoring actually makes the goods and services from the emerging economies more competitive in the world market, and thus can be a contributory factor in the positive trade balance experienced by many emerging economies since early 2000s.     

Environmental policy in the two-country-case

Summary The paper analyzes the problem how environmental policy affects sector structure, the allocation of resources, relative price (and comparative advantage) and national income in a two-country case with varying terms of trade. The frame of reference is a two-sector model in which production generates pollutants as a joint product. If a country exports the pollution-intensively produced commodity environmental policy will improve its terms of trade under suitable conditions with respect to demand. Whereas in the political debate the negative effect of environmental policy on the international competiveness of a country is stressed, the terms-of-trade effect gives more leeway to environmental policy. The effects on output, export, imports and the other variables of the system are discussed.Help for calculating the results is acknowledged to J. Eichberger.

Tradable and nontradable directed technical change

ABSTRACT

We wish to reconcile the major trends in wages and the terms of trade using a directed technical change approach in which: (i) tradable and nontradable goods can be substitutes or complements; and (ii) scale effects can be present or can be partially or totally removed. With a lower skilled labour ratio and a higher relative wage in the tradable sector, the price (real exchange rate or terms of trade) mechanism is crucial in determining sectoral productivity differences and thus wage inequality. Along the balanced growth path, the real exchange rate can be negatively related with the relative productivities in horizontal innovation (the Balassa-Samuelson effect) and with the relative labour level, depending on scale effects. The wage premium increases due to an increase in the relative labour level in the nontradable sector under substitutability with scale effects or under complementarity without scale effects. A calibrated version of the model indicates that the model closely replicates the data for Germany. Moreover, while the Balassa-Samuelson effect is quantified, an increase in the relative supply of labour in the tradable sector decreases both terms of trade and inequality.     

International business cycles and the relative price of investment goods

Abstract Is the relative price of investment goods a good proxy for investment specific technology? We model this relative price in a flexible price international economy with two fundamental shocks, namely, the total factor productivity (TFP) shock and the investment‐specific technology (IST) shock. We show that the one‐to‐one correspondence between the IST shock and the relative price of investment goods breaks down in an international economy because of the short‐run correlation between the terms of trade and the relative price of investment goods. The data congruent negative correlation between the investment rate and the relative price of investment goods thus does not necessarily reflect decline in investment frictions (rise in IST), as suggested by many studies. A calibration experiment with the US data demonstrates that such an inverse relation between rate of investment and the relative price of investment goods basically reflects the positive effect of TFP on the terms of trade for a broad range of economies where the home bias in consumption exceeds investment and there is a sizable adjustment cost of investment.     

DUALITY WITH SECTOR‐SPECIFIC EXTERNALITIES UNDER SOCIAL CONSTANT RETURNS*

We develop dual approaches to quantity and price relationships of production in a general multisectoral model with sector‐specific externalities. The production of each good exhibits socially constant returns to scale but privately decreasing returns. We find that the Stolper‐Samuelson theorem holds for factor intensity ranking from the social perspective and that the Rybczynski theorem holds for factor intensity ranking from the private perspective. The price‐output dual fails to hold in general. Moreover, we re‐establish the Heckscher‐Ohlin theorem in the two‐sector case, as well as the factor endowment–factor price and price‐output comparative statics in the high‐dimension case under proper conditions.     

MONOPOLISTIC COMPETITION WITH EFFICIENCY GAPS AND A HECKSCHER‐OHLIN TRADE PATTERN*

We develop a two‐factor, three‐sector model of international trade in which the monopolistically competitive firms are characterized by different fixed production costs. We show that, depending on the pattern of the international distribution of factor endowments, the trade pattern is determined not only by relative factor endowments as suggested by Heckscher and Ohlin, but also by absolute factor endowments via a mechanism of competitive selection in the monopolistically competitive sector.     

Factor Endowments and Industrial Structure

What determines industrial structure? Do sector‐specific characteristics such as unionization, regulation, and trade policy dominate production patterns? One is inclined to believe so based on countless industry‐level studies and the many political battles that are continually fought over trade and industrial policy. In contrast, standard neoclassical trade theory suggests that industrial structure is primarily driven by relative factor supplies. This paper demonstrates that aggregate factor endowments explain much of the structure of production—independent of industry idiosyncrasies—and quantifies the extent to which shifts in industrial structure in a cross‐section of countries are driven by the broad forces of factor accumulation. These results are reached through an empirical application of the factor proportions model of production.

A multivariate time series analysis of the United States aggregate production function

This study examines the effects of hours of work per unit of private sector capital, the relative price of energy, government capital per unit of private sector capital, and inflation on private sector output per unit of capital in the U.S. over the period 1952–90. A small vector autoregressive model that comprises the variables typically employed in single-equation estimates of the aggregate production function is used. Variance decompositions and cumulative impulse response functions indicate that hours of work per unit of private sector capital, the relative price of energy, and the inflation rate have significant effects on private sector output per unit of capital over the 1952–90 period. However, there is no evidence of a significant effect for government capital per unit of private capital. An historical decomposition that begins in 1973 with the emergence of a “productivity slump” and continues through 1990 indicates that shocks to hours of work per unit of capital, the relative price of oil, and inflation appear important in explaining output per unit of capital but shocks to government capital are not important.     

PRICES AND PRICE ANALYSIS IN THE FRAMEWORK OF THE NATIONAL ACCOUNTS

The paper discusses the role of prices in the framework of the new System of National Accounts (SNA) in terms of three major uses: (1) deflation, (2) price indicators, and (3) price analysis. Following a brief review of the price and quantity measures required by the new SNA with its emphasis on deflation of commodity flows and input-output accounts, in addition to the more conventional deflation of final demand categories, the paper discusses some of the conceptual, methodological and data problems involved in implementing the various uses of prices in the new SNA. Implementing the use of prices as deflators depends, in part, on the concept of output selected (national versus domestic; gross versus net), and which of six concepts of valuation, ranging from purchasers'value to true factor cost, is used. Some of the difficulties in deflating nonmarket flows (e.g., interplant transfers) and industry value added, based on the double deflation method, are discussed. In concept price deflators, which have shifting weights, cannot be used as price indicators, which should have fixed weights. In practice, this is often disregarded and the deflators are used as price indicators. The paper support the SNA recommendation for the development of price indexes with fixed weights to be used as price indicators, in addition to the implicit price deflators. Research in the United States indicates that differences in weights can result in different price measures for various subperiods, components of demand and sector output. Periodic revisions in weights to provide more current fixed weights for price and quantity indexes in each subperiod may minimize the problem but it introduces a new problem—lack of comparability with the constant price tables in the SNA which have fixed weights for the entire period. The new SNA provides a comprehensive and integrated framework for price analysis including the analysis of the structure of aggregate price changes, the industrial origin of final demand prices, and the impact of price change in one sector of the economy on the rest of the economy. Some major gaps which need to be overcome in order to implement the use of the new SNA for price analysis include the development of industry capital stock estimates, separate estimates of proprietors’income, reconciliation of value added and distribution share estimates, and the development of a wide variety of information to supplement the conventional input-output tables in the SNA. Implementing the various objectives of price measures within the framework of the accounts will require a number of improvements in existing price measures and expanding the scope of coverage. “List” prices should be superseded by “transactions” prices and better techniques and data need to be developed to provide for quality adjustment of prices. Coverage will need to be expanded to include services, freight rates, trade margins, government expenditures, and also fill in gaps for many manufactured products. Finally, where possible, use of unit values as price indexes or deflators, e.g., imports and exports, should be replaced by direct price measures.     

Natural gas,trade and sustainable growth: empirical evidence from the top gas consumers of the developing world

Natural gas is the key non-renewable source of energy for a low-carbon economy. The research applies heterogeneous panel techniques to investigate the impact of natural gas consumption on economic growth across a panel of top 15 natural gas consumers of the developing world. We establish long-run dynamics with cross-sectional dependence and heterogeneity across the sample countries. The long-run output elasticities suggest that the natural gas consumption and trade variables have significant positive effect on the output in a panel of developing economies. Further, we establish feedback relationship among gas consumption, output and trade in the short-run. Given the significance of natural gas as the low-emission source of energy, we suggest governments and policy advisers of these major natural gas consumers to focus on developing pipeline infrastructure for adequate supply, reforming natural gas sector with a competitive price structure to combat excess demand in individual natural gas market. With trade integration, majority of these countries need to incorporate these initiatives to improve the technologies such as combined cycle power plant technology and value-added chemical production technology to achieve sustainable economic growth.     

Contractionary devaluation in the southern cone: The case of Chile

This paper discusses the effects of a currency devaluation on output, employment and the trade balance in a small open economy (Chile). The structure of the foreign trade sector in terms of price elasticities, the sectoral differences in relative domestic value added intensities across exports and import competing industries and the degree of wage indexation, are the main determinants, in our model, of the impact of devaluation. A simulation carried out with a computable macro model for Chile, shows a currency devaluation to be contractionary in the short to medium run.     

大股东制衡、治理战略与信息披露-来自2003年中国上市公司的证据

麦敕勒(Metzler,1949)指出,对大国的进口行业征收关税可能会降低其国内相对价格,因而减少了它在经济中的产量份额。针对这一观点,本文发展了关于国民生产总值(GDP)转换对数函数系统的一个理论模型,并据此估计美国贸易政策对其行业产量份额的影响。通过采用美国及其经济合作与发展组织(OECD)贸易成员国的行业面板数据,并在控制要素禀赋和技术创新对行业产量份额的影响后,得出了在服装和玻璃行业呈现高关税导致低产量份额的经验证据。在控制了由贸易的政治经济因素导致的内生性及运用各类非关税壁垒代替关税作为测量行业保护的工具后,这些发现也同样稳健。因此,本文的贡献在一定程度上弥补了国际贸易中该领域实证研究方面的空白:证明了麦敕勒悖论理论不再只是一种可能性,而的确在服装业中存在。     

Input Intensity: A Missing Link between Production,Trade Patterns,and Environmental Standards

Trade and production implications of a change in environmental policy using the 2 × 2 Heckscher–Ohlin framework are identified. For otherwise identical economies a difference of environmental policy standards generates two effects: the “effective‐endowment effect” where the abatement activity uses up some resources of the economy leaving less for the production of the final goods and the “factor‐price effect” where changes in the abatement requirement affects factor prices that in turn affect production. The direction and relative strengths of these two effects determine whether production and trade patterns are consistent with or opposite to the pollution haven expectation.     

On Terms of Trade and Capital Accumulation

This paper studies, within an OLG general equilibrium framework, the role of relative factor intensities in determining the relationship between the terms of trade and the capital stock. It shows that a diversified production equilibrium can be characterized by a positive association between these two variables if the investment sector is more labor-intensive and sector technologies are relatively dissimilar. Therefore, capital accumulation and terms-of-trade improvements do not require an import sector growing faster than the export sector when the latter is more capital-intensive. Large Stolper–Samuelson effects on factor incomes drive the results.     

Trade Reform and Informal Wages

When trade reform contracts protected formal sectors in developing countries and the formal workers move to the informal sector for employment, does that reduce informal wages? Using a 2 × 2 Heckscher–Ohlin–Samuelson (HOS) structure with formal–informal production organization for the same commodity, we show that a tariff cut in the import‐competing sector increases both informal wage and employment under very reasonable assumptions. An increase in the price of the export commodity will also increase informal wages, although aggregate informal employment unambiguously falls even if the informal export sector is labor intensive. Furthermore, the formal–informal segmentation of each sector opens up an interesting, hitherto unexplored, possibility that the informal export sector may contract despite a price increase in this sector. Change in the overall size of the export sector is also ambiguous and conditional on the relative strengths of changes in these two segments.     

Resource Rights and Markets in a General Equilibrium Model of Production

Rights to a free resource lead to distributional deadweight losses in partial equilibrium. The present paper examines related distortions in a general equilibrium model of production with output prices constant for the small open economy. The free resource can result in lower output than a market with weak substitution in the other sector. The free resource also leads to a convex production frontier implying a price increase lowers output in the sector. Regarding policy, an import tariff, export subsidy, or price support would lower sector output. These general equilibrium distortions increase the incentives to favor resource markets over rights.
