Comment on “C.E.S. production functions in the light of the Cambridge critique”

The controversy revived in Bertram Schefold’s paper is based on three common assumptions: (1) the underlying techniques are linear (2) perfect competition obtains (3) the economy operates in a putty-putty context. The consequences of dropping these assumptions are discussed, and the relation between nonlinearity and the error due to the use of an “imprecise” production function is examined.     

Pricing policy of a U.S. telephone company

This paper analyses the pricing policy of a major U.S. telephone company in 1967. A mathematical programming model was used to calculate the prices per telephone call on each of three representative routes in each of four periods of the day which would be implied by a variety of alternative maximands (consumers' plus producers' surplus, profit, sales units, sales revenue), under a variety of alternative profit constraints and assuming capacity to be either fixed (at 1967 levels) or variable. Cost and demand data were supplied by several telephone company officials, and supplemented by published material. Sensitivity analysis was carried out on the demand elasticities. A total of one hundred versions of the model are reported on. Our major conclusions include: (i) Maximising consumers' plus producers' surplus subject to a pair of minimum profit constraints provided a good approximation to 1967 policy. (ii) There is perfect discrimination between large and small users for interstate toll calls. (iii) The effect of the state regulatory commission was to keep down the price of intrastate toll calls at the expense of interstate toll calls. (iv) As alternatives to regulation, perfect competition, if attainable, would increase benefits by about $100 million whereas perfect monopoly would reduce them by $300 million per annum, within the area of the company's operations.     

Control of SO2 emissions from power plants: A case of induced technological innovation in the U.S.

This paper investigates how the details of government actions induce innovation—the overlapping activities of invention, adoption and diffusion, and learning by doing—in “environmental technology,” products and processes that either control pollutant emissions or prevent emissions altogether. It applies multiple quantitative and qualitative measures of innovation to a case subject to several “technology-push” and “demand-pull” instruments: sulfur dioxide control technology for power plants. The study employs analyses of public R&D funding, patents, expert interviews, learning curves, conference proceedings, and experience curves. Results indicate that: regulation and the anticipation of regulation stimulate invention; technology-push instruments appear to be less effective at prompting invention than demand-pull instruments; and regulatory stringency focuses inventive activity along certain technology pathways. Increased diffusion of the technology results in significant and predictable operating cost reductions in existing systems, as well as notable efficiency improvements and capital cost reductions in new systems. Government plays an important role in fostering knowledge transfer via technical conferences, as well as affecting the pattern of collaborative relationships within the technical research community via regulatory changes that affect the market for the technology. Finally, the case provides little evidence for the claim that cap-and-trade instruments induce innovation more effectively than other instruments.     

The demand for traded and non-traded goods in the U.S.

Annual postwar U.S. data are used to estimate the Rotterdam demand model for traded and non-traded goods. The estimated income elasticity is 1.51 for traded and 0.64 for non-traded goods, while the own-price elasticities are both between −0.3 and −0.2.     

Pareto vs. Wicksell on adjustment costs in consumption: A reformulation

Pareto's adjustment cost model generating cyclical consumption patterns and Wicksell's observation that it contains mathematical errors are analyzed. An alternative model capturing the essence of Pareto's model and meeting Wicksell's criticisms is proposed where it is shown that consumption and leisure patterns may be cyclical over time.     

The changing structure of cost and demand for the U.S. telecommunications industry

This paper formulates a multiproduct structural model to examine the evolution of the structures of production and demand and their dynamic interaction, over an extended period, 1935–1987, in the U.S. telecommunications industry. We estimate the degree of scale economies, cost elasticities, input price elasticities and the determinants of demand for outputs and for various factors of production. The contributions of the quasi-fixed inputs, such as R&D and physical capital, in the evolution of this industry are evaluated. A number of important issues like the changing characteristics of demand for and cost of local and toll services and the variation of price–cost margin over time are examined under different economic conditions, market structures and regulatory environments. We also analyze the effects of the 1984 divestiture of the Bell System on the cost structure, employment and capital formation of the U.S. telecommunications industry.     

Environmental regulation and U.S. states' technical inefficiency

Using data on 48 states from 1982–1994, we estimate the impact of environmental regulation on technical inefficiency of U.S. states' manufacturing sector. The result indicates that environmental stringency has significant and positive impacts on U.S. states' technical inefficiency.     

Corruption perceptions vs. corruption reality

This paper examines the accuracy of corruption perceptions by comparing Indonesian villagers' reported perceptions about corruption in a road-building project in their village with a more objective measure of ‘missing expenditures’ in the project. I find that villagers' reported perceptions do contain real information, and that villagers are sophisticated enough to distinguish between corruption in a particular road project and general corruption in the village. The magnitude of the reported information, however, is small, in part because officials hide corruption where it is hardest for villagers to detect. I also find that there are biases in reported perceptions. The findings illustrate the limitations of relying solely on corruption perceptions, whether in designing anti-corruption policies or in conducting empirical research on corruption.     

Liberalizing U.S. Trade with the Eastern Bloc: What are the consequences?

This paper provides estimates of the trade and welfare consequences of removing the high discriminatory tariffs that the United States imposes against imports from the Soviet Union and its allies. These imports are now taxed at Smoot-Hawley rates. The estimates of the trade effects exceed those of previous studies, in part because the recent “Tokyo Round” of multilateral trade concessions has increased the tariff discrimination against the non-MFN (Most Favored Nation) suppliers. The study is the first to assess the welfare consequences of eliminating this discrimination. It is estimated that the overall annual gain to the United States would be about $1.8 billion and that the annual gain to the communist suppliers would be between $1.2 billion and $1.7 billion.     

Small is beautiful but large is not to be belittled: a comment on Eijffinger et al. [Eur. J. Political Economy 18 (2002) 365–374]

Eijffinger et al. [Eur. J. Pol. Econ. 18 (2002) 365] find that the research performance of the National Central Banks (NCBs) of the European System of Central Banks is inversely related to their size, or that “small is beautiful”. Their analysis is based on journal articles published by NCB researchers. In the case of the Bank of Italy, their data does not reflect the true number of papers published. Their conclusions may accordingly require modification.     

Inequality persistence through vertical vs. horizontal coalitions

This paper aims to contribute to a better understanding of the observed high persistence of cross-country differences in inequality. It focuses on the interactions between inequality and the predominance of either horizontal coalitions (among individuals of similar economic status) or vertical ones (among individuals with different economic status). A model is proposed showing that the interactions between inequality and the type of coalition formed in a society can give rise to self-sustained social contracts where inequality persists. Key mechanisms of the model are illustrated using the transformation in inequality, redistribution and social relations in Modern England, as well as the “paternalist” system of the US South at the beginning of the XXth century.     

The Quantity and Quality of Schooling and U.S. Labor Productivity Growth (1870–2000)

This paper accounts for the contribution of the quantity and quality of schooling to worker productivity growth in the United States from 1870 to 2000. Schooling investments rose dramatically over the period before leveling off around 1970. Schooling likely caused 30 to 40 percent of the fivefold rise in worker productivity from 1870 to 1970 and produced a “wave pattern” in productivity growth (previously attributed solely to the timing and diffusion of important technological innovations). The results suggest that about 1 percent of the century-long 1.6-percent growth rate in worker productivity is sustainable. Journal of Economic Literature Classification Numbers: O47, J24.     

The contributions of W. H. Hutt

Conclusions We feel that we understand another when his points seem consistent with our prior beliefs. The great difficulty that Hutt faced was that the concepts comprising the macroeconomic superstructure, in which—by now—so many have so much invested, are difficult to integrate with an understanding of how a money-using catallaxy functions. He believed that he had to go beneath them, to some kind of foundation on which we could all agree, and then construct almost a parallel universe, a new (which he always insisted was old) conceptual structure adequate to the task.His exposition is considerably less unfamiliar to those already well acquainted with the subjectivist analysis of catallactic processes. William Hutt was driven by his understanding that the market excels at producing and equitably distributing wealth. Economists could help, or at least not get in the way, only if they understood the functioning of a monetary catallaxy. Developing and conveying that understanding was Hutt's life work, and in it there is much of value that the well-read Austrian cannot afford to miss.An earlier version of this paper was presented at the History of Economics Society meeting in Richmond, Virginia, June 1989.     

Explaining the US–EU productivity growth gap: Structural change vs. intra-sectoral effect

This paper proposes a decomposition of labour productivity growth in the EU15 and the the US since the mid 1990s. The results suggest that the EU's relative slowdown is due to modest “pure” gains of productivity within sectors.     

U.S.-Japanese competition in high-technology fields

As Japan has moved abreast of the United States in the export capability of high-technology products, the competition between the two countries has intensified not only in private sector R&D but also in terms of increased governmental assistance and protectionist measures. This increased competition can be seen in the three electronics industry cases of semiconductors, computers, and robotics, and is specifically illustrated by Japan's VLSI and fifth generation computer projects and the FBI-IBM sting operation in Silicon Valley. All portend a greater technological rivalry, with continuing critical consequences for society.     

Labour demand under VES production and imperfect output market conditions: The U.K. manufacturing experience

A labour demand schedule is derived under VES production and imperfect production market conditions. Tests on UK manufacturing data suggest the importance of current output and to a lesser extent labour cost and the effects of adjustment costs on the employment decision. Substitution possibilities, dependent on the ratio of labour to capital's share generally lie between zero and unity.     

Housing decisions and the U.S. income tax: An econometric analysis

This paper examines the effects of the current income tax treatment of owner-occupied housing on the quantity of housing consumed and on the tenure choice by various groups. Cross-sectional data for 1970 are used to estimate jointly tenure choice and housing demand equations. The equations' parameters are used to assess the efficiency and equity implications of the relevant tax law provisions.     

Adoption of an IMF programme and debt rescheduling. An empirical analysis

The existence of an empirical relationship between the adoption of an IMF programme and the concession of a debt rescheduling by commercial creditors is tested using a bivariate probit model. If countries who have arrangements with the IMF are more likely than others to obtain a rescheduling of their external debt, we could conclude that the adoption of an IMF programme could work as a sort of signal of a country's “good intent” which is thus rewarded with the debt relief. The results confirm the existence of a significant effect of the adoption of an IMF programme on the subsequent concession of a debt rescheduling by private creditors.     

Harassment, corruption and tax policy: a comment on Marjit, Mukherjee and Mukherjee [Eur. J. Political Economy 16 (2000) 75–94]

This comment on Marjit, Mukherjee and Mukherjee [Eur. J. Political Economy 16 (2000) 75–94] shows that their basic model can be simplified by an alternative formulation. A corrupt auditor gives two choices to a taxpayer: pay bribe and evade tax or be overtaxed. Although harassment can be redressed through court, the taxpayer chooses to pay bribe. However, as this note discovers, the bribe–income ratio will critically depend on whether the taxpayer can afford the court fees. This may lead different income groups to have different preferences for corruption.
