Prices in input-output: The INFORUM experience in modeling the U.S. deregulation of domestic oil

Prices, and particularly relative prices, have moved in recent years to the center of our attention. Soaring oil prices, large increases in agricultural prices, and rising costs of product materials and finished goods on world markets have set in motion major changes in the world economy. To model these changes, it has been necessary to use input-output analysis, for our input-output models have the necessary detail to trace these effects. This use of input-output may seem paradoxial to those who, for many years, dismissed this technique because it allegedly fails to take account of the effects of prices. The truth turns out to be almost the reverse: Only input-output can take full account of prices.This paper shows how prices work in the INFORUM model of the American economy. Specifically, it describes how the model generates prices, uses the prices in equations for personal consumption, and changes input-output coefficients on the basis of relative prices. Finally, it compares runs of the entire model to examine the effects in the U.S. of increasing domestic oil prices to world levels.     

Policies for food production and consumption in underdevelopment: The case of Mexico

This paper presents a system analysis approach for the investigation of the most effective agricultural and nutrition-intervening programs for improving the nutritional standards of the rural poor in a lesser developed country. The research is framed within a four-stage process. First, by means of observation, stylized patterns of nutritional status, food consumption, autoconsumption, and crop production are inferred. Second, based on previous anthropological case studies and statistical surveys, a theoretical model of the peasant household is specified. Third, the model is validated by comparing its empirical solution with the observed patterns. Fourth, the model is used to illustrate a method for evaluating alternative programs for improving the nutritional intakes of peasants. Programs appraised are credit for agricultural production, policies for affecting corn prices and input prices, and programs for subsidizing purchases of foods.The empirical study is about the peasant economy of Puebla in Mexico. The major foods of the typical diet and crop pattern of this area are corn (an energy food) and beans (a protein food). This diet is representative of other areas in Mexico and Central America.     

From oil shortage to oil glut: Simulation of growth prospects in the Nigerian economy

During the 1970s, the economy of Nigeria provided one of the most interesting cases of development financed through oil revenue. Between 1970 and 1980, the country's GNP grew at an outstanding rate—after the transition from oil shortage to oil glut, the economy of Nigeria ran into dramatic financial difficulties, which are now placing major constraints to its development. To investigate the transition from an oil-based economy to a stage characterized by greater diversification of exports and more balanced sectoral growth, a model has been built by the University of Ibadan in Nigeria. The model was developed in association with Project LINK staffing for the future inclusion in the Project. According to the finding presented in the study, the annual growth rate of GDP of Nigeria between 1980 and 1988 will be around 2.5 percent. To compensate the drop of the foreign exchange earnings caused by the contraction of oil prices and demand, a vigorous export drive of agricultural products is simulated.     

Farmers’ behaviors and performance in cooperatives in Jilin Province of China: A case study

Agricultural cooperatives began to emerge in China since the 1990s, as a new form of agricultural production that better handles challenges brought by market shifts and globalization. Little research has been done to understand factors that decide farmers’ behaviors and performance in cooperatives in China. Using large sample data from Jilin Province, this paper examines the decision-making mechanism of farmers in joining cooperatives and analyzes farmers’ awareness of cooperatives and relative laws, willingness to participate, real behaviors and performance in cooperatives. Empirical results show that farmers’ education level, the variety of agricultural products, planting area, future planting plan, sales difficulties, low prices of agricultural products, labor shortage, agricultural production costs and risks are the most influential factors in deciding what behaviors to take, while planting area, agricultural production costs, the variety of agricultural products and lack of agricultural insurance are the most influential factors deciding the final performance achieved. This paper concludes with policy suggestions, such as strengthening publicity of cooperatives, standardizing internal management of cooperatives, and enhancing the quality of services provided by cooperatives.     

The economic effects of common agricultural policy on Mediterranean montado/dehesa ecosystem

The decoupling of CAP payments leads production decisions and resources allocation to be more dependent on market prices and competitive advantages. The objective of this paper is to assess the effects of CAP trends on the montado/dehesa traditional ecosystem of Mediterranean regions in terms of farm income, land, labour and capital. A positive mathematical supply model disaggregated by the montado agro-forestry production systems of the Alentejo region in southern Portugal is developed. The results show that decoupling payments of CAP have negative economic effects on agricultural activities and resource use. Agricultural income increases with single farm payments but the foreseen increases in prices do not compensate the loss of the Agenda 2000 area payments in terms of competitiveness. These results reinforce the need to promote alternative agricultural and non-agricultural activities and policies in Mediterranean rural European areas and regions.     

Two alternative methods of removing price supports: Implications to the U.S. corn and livestock industries

A U.S.-Nebraska linked quarterly econometric model is used to examine impacts on the corn, beef, and hog industries from immediate and gradual removal of price supports. The results indicate that the agricultural sector is more adversely affected from removal of price supports gradually than expeditiously. Also, the gradual adjustment approach produces greater cyclical movements in prices and quantities. Corn exports are not greatly affected under either market adjustment process.     

A model of the Canadian global exchange rate: A test of the 1970s

A review of the literature indicates that no single exchange rate model has been able to track successfully the movements of the Canadian dollar for both the 1970–1976 period and the period thereafter. The purchasing power parity model, irrespective of whether based on relative wholesale prices, unit labor costs, GNP deflators, or export prices performs very poorly; the monetarist models collapse because of their strict adherence to the purchasing power parity and interest rate parity assumptions; the portfolio demand models require a significant adjustment for the post-1976 period. This paper presents a medium-term eclectic model of the global exchange rate of the Canadian dollar and examines a spectrum of broad issues that reflect on the efficiency of the foreign exchange market of Canada. These issues are basically related to the interest parity assumption, the role of speculation, and the test of rational expectations. The global exchange rate is defined as the value of the Canadian dollar measured in terms of a unit of basket of currencies comprising currencies of France, West Germany, Japan, the U.K., and the USA. The model belongs to the same genre of balance of payments structural models that explain the exchange rates by balancing demand and supply of foreign currencies. The model simultaneously explains both spot and forward rates, and it has been estimated and tested by using the quarterly data for 1971–1981.     

A small forecasting model of the world oil market

An annual, small-scale econometric model of the world oil market was developed to analyze oil market conditions and oil prices for the period 1986–1991. The model determines the oil price by a market-clearing condition, given world economic activity and the strategic supply behavior of the OPEC core countries. The effects of OPEC production cut in 1987 upon oil prices are evaluated, and alternative oil price profiles are provided. A simulation experiment suggests that if the OPEC core is pressed to defend the OPEC share in oil supply, then wide price swings may become inevitable.     

Codependent Cycles of Chinese Inflation

对我国通胀率、农产品价格和M2等三个变量进行相依性周期的检验与分解表明,农产品价格周期波动剧烈,在很大程度上为“圈地”等导致的粮价波动以及诸如猪肉价格暴涨暴跌等因素对农产品价格的冲击效应。阕此,将现行的粮食收购保护价改革为粮食生产保护价与销售保护价,将减弱粮价等因素对农产品价格和通胀的冲击强度。农产品价格与通胀率和M2的周期弱相依,M2与通胀率的周期强相依,它们周期成分的交点形成“梭形”,说明我国货币政策目标在抑制通胀和促进增长之间交替转换。在农产品价格周期处于基本平稳时,可实施适度宽松的货币政策刺激经济增长,但其扩张幅度应以M2的相依周期成分扩大至1．5左右为宜;在农产品价格怏速上涨或者周期成分的上升期,应以抑制农产品价格为先导,刺激经济增长的适度宽松货币政策宜延缓至农产品价格周期处于平稳或者下行期,再予以实施。     

Codependent Cycles of Chinese Inflation

A test and decomposition of the codependent cycles of the consumer price index (CPI), agricultural producer price index (APPI) and M2 reveals that the sharp cyclical fluctuations in agricultural producer prices largely stem from the grain price fluctuations induced by factors such as land enclosure and the impact on APP of the abrupt changes in pork prices and other factors. Therefore, changing the current policy of grain purchasing price subsidies to one of subsidies to grain production and sales will reduce the impact of grain prices and other factors on APP and inflation. The weak cyclic codependence among APP, CPI and M2, along with the strong cyclic codependence between M2 and CPI, has given rise to a “shuttle-shaped” intersection of cyclic elements. This indicates that China’s monetary policy goal has been alternating between curbing inflation and stimulating growth. When the APP cycle is basically stable, China can implement a moderately easing monetary policy to stimulate economic growth, but this must be based on a 1.5 or so margin of increase in the codependent cycle components of M2. When APP rises sharply or is in the rising phase of cycle elements, China should emphasize APP control, and should delay the moderately easing monetary policy till the APP cycle becomes stable or is in the downlink phase.     

Policy modelling of the trade-off between agricultural development and land degradation—the Sudan case

The agricultural policy model of the trade-off between agricultural growth and land degradation that we have developed, with Sudan as an application, shares common features with the computable general equilibrium (CGE) models. The model is used to address two questions. First, what are the future prospects of a green gross domestic product (GDP), are there reasons for alarm or not, and to what extent? Secondly, which among the four policies of price incentives, property rights, poverty reduction, and human capital are more effective than the others? We show that the prospects of natural resource-friendly agricultural development in Sudan—a rising green GDP—are not promising in the medium run, but that, indeed, there is a range of effective policies and choices that could reduce the trade-off between economic growth and land degradation.     

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.     

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.     

The role of productivity growth and farmers’ income protection policies in the decline of relative farm prices in the United States

The paper emphasizes three interrelated questions about the decline in relative farm to non-farm prices in the United States since 1973: (1) Is it unusual, (2) What caused it, and (3) Is it likely to continue? We find that based on historical and international evidence this phenomenon may be considered unusual. Separating farm price and income support in 1973 and growing relative productivity in agriculture have been the major contributors to changing the trend of the relative farm goods inflation. This trend is likely to continue based on predicted steady growth of relative agricultural productivity and continuation of direct payments and other forms of farm income support policies.

Applied general equilibrium analysis of trade liberalisation on land-based sectors in Malaysia and Indonesia

This paper presents general equilibrium evaluations of forest sector trade for Southeast Asian exporters. The four scenarios examined range from the 1994 Uruguay Round tariff reductions to a complete liberalisation of forest and agricultural products trade. We find that simultaneous reductions in forest and agricultural sector tariffs make Indonesia and Malaysia worse off. For Indonesia, this is due to the fall in forest rent and agricultural tariff revenues. Malaysia has the highest ratio of agricultural imports to total land-based sector imports, the rise in agricultural prices thus hits Malaysian consumers the hardest.We find that terms of trade effect omitted from the partial equilibrium framework may reduce the welfare calculations for Malaysia and Indonesia in the forest sector trade by as much as 106 and 58%, respectively. This points to the importance of general equilibrium modelling in the logging industry. The same applies to other sector specific analyses where trade is concentrated between few countries.     

Stabilization policies in the Greek economy: Will they work?

This paper develops and estimates a short-run model for the interaction between money, output, prices, international reserves, and the exchange rate in a managed floating system in Greece. The framework presented, which is in the spirit of the monetary approach modified to allow for adjustment lags in output and prices incorporates a policy reaction function for domestic credit. The role of inflationary expectations is taken into account. The policy question addressed in the paper by means of the model is whether current economic policies are sustainable and whether stabilization measures leading to lower inflation and smaller fiscal deficits should be pursued.     

Trade liberalization and factor prices: An application to the U.S. manufacturing sector

The effects of a trade policy on the prices of productive factors have important policy implications, particularly with regard to trade liberalization and protection. This paper examines the empirical evidence of the Stolper-Samuelson theorem for 16 major U.S. manufacturing industries. The theorem asserts that international trade reduces the prices of scarce productive factors and hence decreases their shares of income. The elasticities of prices of finished goods with respect to factor prices are estimated and then rearranged in the form of the row stochastic P-matrix in accordance with the proposition of Uekawa. The inverse of this matrix seems to confirm the weak version of the Stolper-Samuelson theorem.     

A quantification of policy reform: an application to the Uruguay Round Negotiations on Agriculture

We employ an empirical general equilibrium model to quantify the welfare effects of trade policy reformation in the Uruguay Round Negotiations on Agriculture. Our approach is two-fold: first we focus on the primary players in the agricultural negotiations: the Cairns Group, the European Union, Japan, and the United States, where the players are defined as benevolent governments whose primary objective is to maximize total welfare, measured in terms of the equivalent variation (EV). Second, we take into account the divergent objectives of different interest groups within the targeted regions, namely from the agricultural and non-agricultural sectors, where different weights given to these sectors depending on their political influence. Here the decision making authorities, or governments, are no longer assumed to focus solely on the maximization of the region’s EV welfare; instead they are assumed to maximize a payoff that is defined by the utilities of the agricultural and non-agricultural interest groups. This is modeled with a Political Preference Function that has a CES functional form.The results lead to several conclusions. The greater the reduction in protection, the greater the increase in welfare for most of the regions of the world. We contend that comparatively moderate reductions were enacted however, because of the relative political power that the domestic agricultural interests possessed in each region.Though the goal of the WTO/GATT is obviously to liberalize trade, only modest gains may be expected in the area of agriculture due to the internal conditions that have been advanced in this paper.     

Imperfect competition,border protection and consumer boycott: The future of the dairy industry in Israel

Recent increases in prices of dairy products in Israel led to consumer unrest and boycotts against dairy producers during the summer of 2011. The Israeli dairy industry is highly distorted with production quotas and administered prices for raw milk, tariff rate quotas and an oligopoly in dairy processing. Since the issue of self-sufficiency and food security is at the top of Israel's national priorities, the future of the dairy industry is generating heated debate. Thus, we use a general equilibrium model to estimate the effects associated with particular alternative policies actually discussed to liberalize the Israeli dairy industry.
