This paper examines the response of gasoline's share of a barrel of crude oil to changes in relative petroleum product prices. An inter-country comparison of the U.S., Canada, and the E.E.C. allows investigation of different parts of the production possibility frontier. In the U.S. and Canada, with relatively large amounts of cracking capacity, there is price responsiveness of the product mix to changes in relative product prices. In the U.S., both residual and distillates are substitutes in production for gasoline, but for Canada, only distillate is a substitute. Part of this difference is attributed to the U.S. oil quota. For the E.E.C. with relatively small amounts of cracking capacity there was no discernible effect of product prices on product mix. 相似文献

We employ the term structure of gasoline and heating oil prices, proxied by convenience yields, to explain the variation in the spread between the prices of gasoline and crude oil and the prices of heating oil and crude oil. We demonstrate that the marginal convenience yields in the gasoline and heating oil markets explained much of the variation in the spreads between 1986 and 1999. The evidence indicates the importance of a disaggregated treatment of the term structure of prices: the convenience yield is found to explain a substantially higher amount of the variation in the spread when it is decomposed by maturity, even after controls for seasonality and inventory levels are implemented. These findings support the notion that the futures term structure contains information beyond what can be garnered via obvious or easily available proxies of current supply and demand. The findings are also supported in an alternate specification that tests for the origins of information spillover (leadership) between the commodities: it is demonstrated that decomposed convenience yields explain a substantial portion of the volatility spillover from the gasoline and heating oil markets to the crude market. 相似文献

An integrated monopoly, where two complements forming a composite good are offered by a single firm, is typically welfare superior to a complementary monopoly. This is ‘the tragedy of the anticommons’. We analyse the robustness of such result when competition is introduced for one or both complements. Particularly, competition in only one of the two markets may be welfare superior to an integrated monopoly if and only if the substitutes differ in their quality so that, as their number increases, average quality and/or quality variance increases. Then, absent an adequate level of product differentiation, favouring competition in some sectors while leaving monopolies in others may be detrimental for consumers and producers alike. Instead, competition in both markets may be welfare superior if goods are close substitutes and their number in each market is sufficiently high, no matter the degree of product differentiation. 相似文献

About 40 percent of US corn is now used to produce biofuels, which are used as substitutes for gasoline in transportation. In this paper, we use a Ricardian model with differential land quality to show that world food prices could rise by about 32 percent by 2022. About half of this increase is from the biofuel mandate and the rest is a result of demand‐side effects in the form of population growth and income‐induced changes in dietary preferences, from cereals to meat and dairy products. However, aggregate world carbon emissions would increase, because of significant land conversion to farming and leakage from lower oil prices. 相似文献

Energy security is crucial for sustaining high economic growth in India. This article empirically estimates India’s long- and short-term demand relations for crude oil, diesel and petrol (gasoline) using the ARDL and ECM cointegration procedures and then uses them to project demand for these products up to 2025 under various scenarios of GDP growth and oil prices. Our projections show that over 2012 to 2025, demand is likely to increase by about 74% for crude oil, 117% for diesel and 136% for petrol – the annual growth rates being about 4.3% for crude oil, 6.1% for diesel and 6.8% for petrol (gasoline). This article suggests that India needs to (1) take measures to improve efficiency in the use of petroleum products; (2) try to enhance supplies such as through production sharing agreements by Indian oil companies with other countries and (3) increase the use of nuclear, hydro, solar and other alternative energy sources, as Western European countries have done. 相似文献

This paper considers technology transfer in a Cournot-duopoly market where the firms produce horizontally differentiated products. The patent licensing contract consists of up-front fixed fee and per-unit output royalty for products of neither close substitutes nor isolated. In case the goods are close substitutes then only per-unit output royalty is the optimal solution. However, whether the incentive for imitation increases with product differentiation is ambiguous. Further, in case of credible imitation threat, the relationship between better technology transfer and product differentiation may be ambiguous. We have briefly addressed the implications of multiple licensing. 相似文献

The Effect of Repeated Interaction on Contract Choice: Evidence from Offshore Drilling 总被引:2,自引:0,他引:2
We argue that repeated interaction and high-powered formal contractscan be either substitutes or complements, depending on the relativeimpact of repeated interaction on incentive problems and contractingcosts. In the offshore drilling industry, we find that oil andgas companies are less likely to choose fixed-price contractsas the frequency of their interaction with a driller increases.This supports the conclusion that repeated interaction and high-poweredformal contracts are substitutes in this setting, indicatingthat repeated interaction reduces incentive problems more thancontracting costs. In addition, we find that using instrumentalvariables to account for the endogenous matching of drillersto projects strengthens our results. 相似文献

It has been documented that retail gasoline prices respond more quickly to increases in wholesale prices than they do to decreases in wholesale prices. However, there is little empirical evidence that identifies the link between the pass-through of oil prices to gasoline in different volatility regimes. Using a Markov-switching model on weekly observations of fuel prices from 1990 to 2011, we find that fuel prices respond significantly faster to increases in crude oil prices than to decreases in crude oil prices. However, when volatility is low, the transmittal of a price change from crude oil to retail fuel is higher compared to periods of high volatility. These results provide important information on the behavior of retailers. The findings of this paper therefore provide clues for better understanding the recent dynamics of fuel prices and some policy implications. 相似文献

In this paper we analyse the potential asymmetric response of retail prices for gasoline and diesel‐fuel to changes in oil prices for the Spanish economy and its relation with the so‐called ‘rockets and feathers’ behaviour. We show that the assumption made by previous studies, which use as the key explanatory variable the sign –positive or negative‐ of the change in international oil prices, is inadequate for the Spanish case and the magnitude of the change in international oil prices is also relevant. For small changes in international oil prices there is neither price asymmetry nor rockets and feathers behavior in the retail markets. However, price asymmetries in line with rockets and feathers behavior in retail gasoline and gasoil markets are present when these changes exceed a certain threshold. Following Martín‐Moreno et al. (2018) we first apply an Auto‐regressive Error Correction Model and endogenously estimate the threshold triggering the rockets and feathers behaviour. A time‐varying nature for the dynamic response of retail prices to oil price shocks is revealed when we estimate the TAR‐ECM model using rolling windows. Hence, in a second stage, we use a Markov‐switching estimation of the model to test the robustness of the results given its suitability to changing environments. This study could have relevant policy implications for the Spanish gasoline and gasoil retail markets due to the ongoing debate on the existence of a rockets and feathers behavior in gasoline and gasoil retail markets between the Spanish regulatory body and the oil companies. 相似文献

The purpose of this paper is to investigate the incentive for a firm to innovate a (patented) substitute or complement for an existing product under a variety of market arrangements, then to compare the ranking of incentives with the ranking of increments to social welfare caused by the product's introduction. It is found that though monopoly is a spur to the innovation of substitutes, these will usually come from outside firms. Competition is a spur to the innovation of complementary goods. In general, products are innovated first in markets where welfare increases most, though there are caveats to this. 相似文献

To identify the relevant product markets for Swedish pharmaceuticals, a spatial econometrics approach is employed. First, we calculate Moran's Is for different market definitions and then we use a spatial Durbin model to determine the effect of price changes on quantity sold of own and competing products. As expected, the results show that competition is strongest between close substitutes; however, the relevant product markets for Swedish pharmaceuticals extend beyond close substitutes down to products included in the same class on the four‐digit level of the Anatomic Therapeutic Chemical system as defined by the World Health Organization. The spatial regression model further indicates that increases in the price of a product significantly lower quantity sold of that product and in the same time increase the quantity sold of competing products. For close substitutes (products belonging to the same class on the seven‐digit level of the Anatomic Therapeutic Chemical system), as well as for products that, without being close substitutes, belong to the same therapeutic/pharmacological/chemical subgroup (the same class on the five‐digit level of the Anatomic Therapeutic Chemical system), increased competition is also visible after 1 July 2009 when the latest policy changes with regards to pharmaceuticals have been implemented in Sweden. 相似文献

Using a computable equilibrium model, the short-run effects of a radical liberalization of the West European natural gas and electricity markets are examined. In each model country, oil, gas, coal and electricity are produced, traded and consumed. There are world markets for oil and coal, and well-integrated competitive markets for gas and electricity in Western Europe. Gas and electricity are transported and traded across markets under the assumption of ideal third-party access regimes for transportation and limited capacities in the transportation networks. It is found that relative to the data year 1996, radical liberalization reduces the average end-user price of natural gas by around 20%, and the average end-user price of electricity by around 50%. The supply of electricity increases by around 20%, mainly due to increased coal power production. After such liberalization, coal power emerges with the largest market share of electricity production in Western Europe. 相似文献

This paper investigates substitution among such alternate fuels as coal, natural gas, and electricity during the actual oil price increases of 1970s. These substitution adjustments are assumed to be dynamic and modelled by a partial adjustment structure. This dynamic structure is incorporated into a translog cost technology. Short- and long-run price elasticities are estimated by identifying inter- and intra-industry variations. The models are estimated with a sample of 88 pooled observations, including distillate and residual oils purchased by eleven 2-digit manufacturing groups (1974-81). Models are estimates are strictly negative. These own price elasticities range from (long-to short-run) –2.93 to –2.55 for distillate oil, –0.698 to – 1.53 for residual oil, –0.533 to 0.011 for coal, –0.235 to –0.213 for natural gas, to –0.888 to –0.845 for electricity. Estimastes of both short-run and long-run cross-price elasticities suggest that coal and electric energy are the prominent substitutes for fuel oils. While the relationship between the latter and natural gas remains largely complementary. 相似文献

This article attempts to investigate the issue of asymmetries in the transmission of shocks to input prices and exchange rate onto the wholesale and retail price of gasoline respectively. For this purpose, we utilise the error-correction methodology in the Greek gasoline market. The sample consists of monthly data covering the period of January 1988 to June 2006. We also try to analyse by using impulse response functions the effect of competition on the dynamic adjustment of gasoline price to which has been paid scant attention in the past. The results favour the common perception that retail gasoline prices respond asymmetrically to cost increases and decreases both in the long and the short-run. At the wholesale segment, there is a symmetric response of the spot prices of gasoline towards the adjustment to the short-run responses of the exchange rate. Lastly, after the deregulation, wholesale prices of gasoline tend to gradually restore equilibrium triggered by a price shock compared to the regulated period. 相似文献

We show that international outsourcing and R&D by the outsourced firm may be either substitutes or complements. Outsourcing increases the R&D investment in small markets and in highly competitive product markets, whereas it decreases the R&D investment in large markets. If the outsourced firm can be technologically very efficient under exporting, outsourcing can make the consumers worse off by reducing the R&D investment. If there is skill differential in the production process and outsourcing occurs only in the unskilled activities, R&D‐reducing outsourcing occurs in a relatively low‐skilled industry. If outsourcing of the unskilled jobs reduces the effective cost of the skilled workers by increasing the productivities of the skilled workers, outsourcing provides further disincentive for R&D compared to the situation where outsourcing of the unskilled jobs does not affect the effective cost of the skilled workers. 相似文献

This article employs a bivariate poisson jump model to investigate the relationship between the volatility of crude oil and gasoline especially during the period of the Gulf War. We find that greater jumps occurring in crude oil returns will appear in gasoline returns at the same time, but the magnitude of the co-movements in volatility falls. The covariance is relatively smaller in the Second Gulf War vs. the first conflict. The volatility of crude oil is of significantly high levels during periods of the war, yet the volatility of gasoline is not as sensitive as crude oil, particularly in the second conflict. Furthermore, the jump that occurred by the war did not lead both spot prices to a high persistent level for a long period, which fits the feature of the jump models. All these findings are important to market traders and hedging strategies. 相似文献

We study the interactions between fuel efficiency improvements in the transport sector and the oil market, where the efficiency improvements are policy-induced in certain regions of the world. We are especially interested in feedback mechanisms of fuel efficiency such as the rebound effect, carbon leakage and the “green paradox”, but also the distributional effects for oil producers. An intertemporal numerical model of the international oil market is introduced, where OPEC-Core producers have market power. We find that the rebound effect has a noticeable effect on the transport sector, with the magnitude depending on the oil demand elasticity. In the benchmark simulations, we calculate that almost half of the energy savings may be lost to a direct rebound effect and an additional 10% to oil price adjustments. In addition, there is substantial intersectoral leakage to other sectors through lower oil prices in the regions that introduce the policy. There is a small green paradox effect in the sense that oil consumption increases initially when the fuel efficiency measures are gradually implemented. Finally, international carbon leakage will be significant if policies are not implemented in all regions; we estimate leakage rates of 35% or higher when only major consuming regions implement fuel economy policies. Non-OPEC producers will to a larger degree than OPEC producers cut back on its oil supply as a response to fuel efficiency policies due to high production costs. 相似文献

Economic theory predicts a decrease in valuation as the availability of substitutes increases. This paper describes a contingent valuation (CV) survey that investigates the effect of substitutes on valuation of private market goods. Using an approach that compares willingness to pay (WTP) values elicited from a CV question that accounts for substitutes with WTP values elicited from a similar question without substitutes, we find that allowing for substitutes can moderate WTP values. For the item valued in this study, a hamburger sandwich, allowing for substitutes was associated with a reduction of from 10% to 16% in stated values. 相似文献

This article uses a new identification strategy to estimate the demand for gasoline. I show that the monthly gasoline price is endogenous to gasoline demand at the state level, and that gasoline tax and domestic oil first purchasing price together are strong and valid instruments to correct for the endogeneity bias. In addition to estimating the price elasticity, this article also provides an estimate of the income elasticity. These updated estimates are critical factors in evaluating the environmental effect of gasoline tax and forecasting gasoline consumption. 相似文献

Before introducing cash discounting in retail gasoline markets, major oil companies offered proprietary credit cards as an unpriced service to their customers. This paper analyzes the origins of cash discounting in order to determine why oil companies introduced explicit pricing of the credit service in 1982 only to begin discouraging it by the end of the decade. Sharp increases in nominal interest rates and in the real price of gasoline between 1978–1982 spurred a rapid rise in the cost of financing accounts receivable. This increasing cost in part drove the initial decision to discount. By 1990 the discounting trend reversed as the costs of processing credit transactions and of the float associated with non-revolving accounts receivable fell.
