STOCHASTIC ANALYSIS OF INPUT–OUTPUT MULTIPLIERS ON THE BASIS OF USE AND MAKE TABLES

Although technical coefficients are estimated on the basis of flow data (use and make matrices), they are rarely treated as random variables. If this is done, an error term is added to the coefficients, rather than derived from the distribution of the data. Even so, the calculation of multipliers, by means of the Leontief inverse, is difficult. Due to the nonlinearity of this operation, the multiplier estimates are biased. By going back to the flow data, this paper provides unbiased and consistent employment and output multipliers estimates for the Andalusian economy. Rectangular use and make matrices are accommodated and problems associated with the construction and estimation of technical coefficients and the Leontief inverse are circumvented.     

The use–make framework and the derivation of functional forms in production theory

The use–make framework is employed to explain functional forms in production theory, including Cobb–Douglas and Leontief. Productivity and efficiency are interrelated by augmenting the framework with a linear program that determines the frontier output.     

General competitive equilibrium of the spatial economy : Two Teasers

The local indivisibility of space complicates general equilibrium analysis. Mazzoleni and Montesano (1984, p. 286), suggest that the usual reasoning of the non-spatial analyses of competitive equilibrium can be performed in the context of a commodity space that contains subsets of land. This space, however, lacks a linear structure, so it resists application of the usual reasoning. Two examples will show that Mazzoleni and Montesano's existence results are flawed.     

PRIMARY VERSUS SECONDARY PRODUCTION TECHNIQUES IN U.S. MANUFACTURING

In this paper we analyze the determinants of material inputs into individual production activities as a function of their outputs. We use observations on a large cross-section of U.S. manufacturing plants from the Census of Manufactures, including those that make goods primary to other industries, to study differences in production techniques. We find that in most cases material requirements do not depend on whether goods are made as primary products or as secondary products. We thus elucidate support for the commodity technology model as a useful working hypothesis.

Debreu’s coefficient of resource utilization, the Solow residual, and TFP: the connection by Leontief preferences

Debreu’s coefficient of resource utilization is freed from individual data requirements. The procedure is shown to be equivalent to the imposition of Leontief preferences. The rate of growth of the modified Debreu coefficient and the Solow residual are shown to add up to TFP growth. This decomposition is the neoclassical counterpart to the frontier analytic decomposition of productivity growth into technical change and efficiency change. The terms can now be broken down by sector as well as by factor input.

Outsourcing of Services and the Productivity Recovery in U.S. Manufacturing in the 1980s and 1990s

Manufacturing productivity growth recovered during the 1980s and 1990s, while other sectors, particularly services, did not. In the same period U.S. manufacturing has engaged in the “outsourcing” or “contracting-out” of service functions. Has the recovery of manufacturing been accomplished by industrial reorganization--sloughing off sluggish services--rather than technical progress? We analyze this question by reducing service inputs to their consituent elements of material inputs. Service productivity growth is thus imputed to the goods sectors, reducing the recovery of manufacturing productivity growth in the 1980s by one fifth. The recovery lasted through the 1990s, when high productivity performers in manufacturing have been relatively successful at outsourcing sluggishservices.

     

The Location of Comparative Advantages on the Basis of Fundamentals Only

We propose a new way to locate the comparative advantages of two economies linked by international trade. We construct a competitive benchmark based only on the fundamentals of the two economies: endowments, preferences and technologies. The direction of trade is endogenously determined by a linear program with an input-output core. The factor contents of that trade are compared with factor endowments to test the Heckscher-Ohlin model in the presence of different technologies and preferences. We can also evaluate the gains of free bilateral trade. The model is applied to a customs union between Europe and Canada. The Heckscher-Ohlin factor abundance specialization hypothesis is supported by the data.     

The consumer's index

Consumer's surplus measures the area under the demand curve between two prices, but is path dependent. There exists a path such that consumer's surplus tracks utility and an explicit formula is known for CES utilities. This paper shows that the CES‐based formula holds for any homothetic utility, and I call it the consumer's index. The index modifies consumer's surplus in two ways: the change in income is measured by its growth factor and the area under the demand curve is normalized by income.     

The initial value problem for the trade cycle in euclidian space

[Ten Raa, 1984] has shown how arithmetics ideas carry over to distributions over space and can be used to solve open, static spatial problems such as the determination of urban equilibrium. This article extends the approach to dynamic spatial economics by tracing spatial distributions through time. It is shown that the basic ideas of ordinary differential equations carry over to the present context, provided that ‘functions’ are spatially distributed valued. The consequent differential equations for the distributions are solved. [Puu, 1982] spatial trade cycle model falls out as a special case and its associated initial value problem can now be completely solved.
