Cable Service and Its Implicit Marginal Valuation

The objective is to estimate the implicit marginal value of channel offerings by cable systems in the USA. Hedonic analysis is a convenient framework in which to explore the relationship between the price of cable service and the channels offered by a cable system. Two separate hedonic equations are estimated-- one for the price of analog cable service and one for the price of digital cable service. With regard to the price of analog cable service, the implicit marginal valuation is statistically significant and positive for just 15 of 106 channel offerings and negative for seven channels. For the price of digital cable service, the implicit marginal valuation is statistically significant and positive for just eleven of 105 channel offerings and negative for five channels. The results suggest that a subscriber's utility would be enhanced by a pricing structure different from the typical approach used by cable systems today of offering a bundled package consisting of several channels. One alternative is to allow consumers to subscribe to just those programming services for which they have a positive implicit marginal value (i.e. an a la carte pricing structure).     

A Note on the Technical and Allocative Efficiency of Local Exchange Carriers in the United States

The issue explored is whether incentive regulation of local exchange carriers in the United States has resulted in an increase in efficiency. After providing an overview of the nature of incentive regulation, the methodology for measuring the effects of incentive regulation on efficiency is reviewed. This methodology is data envelopment analysis and allows for the measurement of both technical efficiency and allocative efficiency of individual local exchange carriers. The results of empirically implementing the DEA approach indicate that there is little change in technical efficiency. In fact average technical efficiency in 1988 was the same as in 2001. Next, while outputs continued to grow at about their historical rate across LECs, the sizeable increase in the two types of capital increased inputs well above their historical average rates for some LECs leading to short run allocative inefficiency. On average, however, allocative efficiency shows no identifiable trend between 1988 and 2001. Finally, in the aggregate, total economic efficiency does not demonstrate any trend between 1988 and 2001.     

A note on the measurement of the slowdown in total factor productivity

Investigation of foreign exchange control generally focuses on the black market in currencies and the resultant welfare loss to the country under exchange control. But very little attempt has been made to formulate the internal income transfer from foreign exchange earners who choose not to resort to black market, to importers who receive the foreign exchange at less than free market rate. This paper quantifies such measures of income transfer as importer's cost savings, exporter's income transfer, and the transaction cost loss of the market. A case study is developed using the 1951–74 export figures of the state of Kerala in India, showing that the exchange-earning pure or net exporter pays a hidden subsidy to the exchange-consuming importer; and by extension, an exchange-earning agricultural region of a less developed country subsidizes the import-consuming industrial sector of that country.     

On the Interaction of Risk and Time Preferences: An Experimental Study

Experimental studies of risk and time preference typically focus on one of the two phenomena. The goal of this paper is to investigate the (possible) correlation between subjects' attitude to risk and their time preference. For this sake we ask 61 subjects to price a simple lottery in three different scenarios. At the first, the lottery premium is paid 'now'. At the second, it is paid 'later'. At the third, it is paid 'even later'. By comparing the certainty equivalents offered by the subjects for the three lotteries, we test how time and risk preferences are interrelated. Since the time interval between 'now' and 'later' is the same as between 'later' and 'even later', we also test the hypothesis of hyperbolic discounting. The main result is a statistically significant negative correlation between subjects' degrees of risk aversion and their (implicit) discount factors. Moreover, we show that the negative correlation is independent of the method used to elicit certainty equivalents (willingness to pay versus willingness to accept).     

Industrial energy efficiency: A look at the data

It is extremely difficult to make a precise, quantitative assessment of the impact of the myriad of factors affecting the improvement in industrial energy efficiency. It is certainly not correct to conclude that housekeeping measures alone have led to the observed improvement. Changing product mix among four digit SIC industries within the same two digit classification, variations in capacity utilization (returns to scale) and energy price increases as well as technological innovations have all contributed to part of the realized reduction in energy use per dollar value added over the period of investigation. Unfortunately, data limitations as well as modeling weaknesses prohibit an exact delineation of the impact of each of the factors on the increase in energy efficiency. The best that can be done—and quite convincingly so—is to qualitatively show that unequivocally these factors had an impact on the efficiency with which energy was used in the manufacturing process for the ten most energy intensive industries in the period 1971–1976.     

Energy demand and interfuel substitution in India

This paper applies a translog price possibility frontier to a pooled sample in order to measure the extent of energy substitution effects in the commercial sector in India. The results indicate that relative changes in energy prices have significant effects on energy consumption.     

Delineating the nature and extent of the market for agricultural commodities

In this article, an approach is suggested for defining the nature and extent of geographic and product markets for agricultural commodities relying on the concept of instantaneous causality. The markets for rice are used for the empirical implementation of the approach. The results, based on both domestic and world prices, suggests that the extent of the geographic market changed between 1968 and 1986. This has obvious policy implications.     

A reconsideration of the impact of recalls on the market valuation of a product

This paper looks at the problem of determining the effect on the market valuation of a product of recalls due to safety defects when the analytical framework is misspecified. Using the car market, the results show that it is difficult, if not impossible, to distinguish the effect on the price of recalls from the impact of quality differentials among makes and models.
