Biofuel Producers in a Deregulated Market 解除管制市场中的生物燃料生产商
Pub Date : 2017-05-18 DOI: 10.2139/ssrn.2487836
Hamed Ghoddusi
In the deregulated fuels market, biofuels and fossil fuels are close competitors and substitutes. Thus, biofuel producers are subject to risks due to volatile crude oil and biofuels feedstock prices. This paper proposes a two-sector fuel market with competing oil refinery and biofuel sectors, calibrated for cases of gasoline/ethanol and diesel/biodiesel. The model suggests that ethanol and biodiesel plants will shut-down approximately 40% and 20% of the time, respectively. The skewness of profits is -0.32, in contrast to the 0.91 of feedstock prices. Several firm-level and policy-level options to manage crude oil price risks for biofuel producers are discussed further.
在解除管制的燃料市场,生物燃料和化石燃料是紧密的竞争对手和替代品。因此,生物燃料生产商面临着原油和生物燃料原料价格波动带来的风险。本文提出了一个由炼油和生物燃料部门相互竞争的两部门燃料市场,并针对汽油/乙醇和柴油/生物柴油的情况进行了校准。该模型显示,乙醇和生物柴油工厂将分别关闭大约40%和20%的时间。利润的偏度为-0.32,而原料价格的偏度为0.91。进一步讨论了生物燃料生产商管理原油价格风险的几个企业层面和政策层面的选择。

Winter is Coming: Controlled Conflicts and the Oil-Price Geopolitical-Risk Premium 冬天来了:控制冲突和油价地缘政治风险溢价

This paper presents a simple oil-exporting-country dynamic growth model with investment, consumption, passive military spending, and active military spending. Passive military spending (arms buildup) adds to security, while active military spending (conflict) depletes it, but adds to output and hence civilian capital (as a proxy for geopolitical risk premium in oil prices) in a non-monotonic way (some geopolitical risk is good for an oil exporter, but too much risk is not). It is shown that when the risk premium is sufficiently small, the optimal policy function does not support any positive active military spending at any levels of civilian capital and security. However, with sufficiently high geopolitical risk premium, the model country engages in controlled conflict (positive active military spending) when civilian capital is low. A controlled conflict in the latter case can shift the production function up, allowing the country to boost its consumption and arms buildup. This explains the big increase in the geopolitical risk premium following the Arab Spring, which included, among other disruptions, a military intervention by Saudi Arabia in Bahrain, as well as the smaller geopolitical risk premium following the recent Saudi-led war against the Houthis in Yemen. If oil prices remain low, depleting the civilian capital of Saudi Arabia and other oil-exporters, it may be rational, according to our model, to expect greater military activity, both to deal with geopolitical risks in the region, and to boost oil prices through the geopolitical risk premium.
本文提出了一个简单的石油出口国动态增长模型,包括投资、消费、被动军事开支和主动军事开支。被动的军事开支(军备建设)增加了安全,而主动的军事开支(冲突)消耗了安全,但以一种非单调的方式增加了产出,从而增加了民用资本(作为油价地缘政治风险溢价的代表)(一些地缘政治风险对石油出口国有利,但过多的风险则不是)。结果表明,当风险溢价足够小时,在任何民用资本和安全水平上,最优政策函数都不支持任何积极的主动军事支出。然而,在地缘政治风险溢价足够高的情况下,模式国家在民用资本较低的情况下参与可控冲突(积极的主动军事支出)。在后一种情况下,一场受控制的冲突可以提高生产功能,使该国能够促进消费和军备建设。这解释了阿拉伯之春之后地缘政治风险溢价的大幅上升,其中包括沙特阿拉伯对巴林的军事干预,以及最近沙特领导的对也门胡塞武装的战争之后地缘政治风险溢价的缩小。如果油价保持低位,耗尽沙特阿拉伯和其他石油出口国的民用资本,根据我们的模型,预期更多的军事活动可能是合理的,这既是为了应对该地区的地缘政治风险,也是为了通过地缘政治风险溢价推高油价。

Could a Resource Export Boom Reduce Workers’ Earnings? The Labor Market Channel in Indonesia 资源出口的繁荣会降低工人的收入吗?印尼劳动力市场频道

For a decade from 2000 Indonesia underwent a natural resource export boom. Aggregate income rose, but real labor earnings stagnated. Employment rose mainly in low-skill sectors with predominantly informal employment arrangements. In this paper we reveal causal connections from the aggregate phenomenon of Dutch Disease to these labor market outcomes. We first explain broad sectoral trends, then, integrating data from several national surveys, investigate sources of variation in boom-era labor earnings. We use instrumental variables to address issues of endogeneity and selection in earnings equations. After controlling for individual and district features we find that intensity of oil palm production, a key booming resource export, robustly predicts diminished formal employment, and that lower formality, in turn, robustly predicts lower earnings. Our findings establish causal linkages absent from prior studies, and so provide a structural dimension to ongoing debates over persistent poverty, rising inequality, and lack of educational progress in Indonesia.
从2000年开始的10年里,印尼经历了自然资源出口的繁荣。总收入上升,但实际劳动收入停滞不前。就业增长主要发生在以非正式就业安排为主的低技能部门。在本文中,我们揭示了从荷兰病的总体现象到这些劳动力市场结果的因果关系。我们首先解释广泛的行业趋势,然后,整合来自几个国家调查的数据,调查繁荣时期劳动力收入变化的来源。我们使用工具变量来解决盈余方程中的内生性和选择问题。在控制了个人和地区的特征之后,我们发现油棕生产的强度,一种关键的蓬勃发展的资源出口,有力地预测了正规就业的减少,而正规程度的降低,反过来,有力地预测了收入的降低。我们的研究结果建立了之前研究所缺乏的因果关系,因此为印度尼西亚持续贫困、不平等加剧和教育进步不足的持续争论提供了结构性维度。

Spanish Abstract: Este paper utilizando el Modelo Casi Ideal de Demanda (AIDS) por medio de ecuaciones aparentemente no relacionadas para la industria de combustibles en el sector transporte en Colombia, analiza las elasticidades precio de la demanda, precio cruzada de la demanda y gasto de la demanda de la Gasolina motor, Diesel y Gas Natural Vehicular (GNV), dada la recomposicion que ha presentado esta industria entre el 2003 y 2012, con el objetivo de determinar si estos combustibles se comportan como sustitutos o complementarios y se trata de bienes necesarios o no. Los principales resultados indican que la elasticidad precio de la demanda de la Gasolina y el Diesel son bienes inelasticos, mientras que el GNV se comporta como un bien elastico. Por su parte, por medio de la elasticidad precio cruzada de la demanda, se encuentra que solo el Diesel y el GNV se comportan como bienes sustitutos, mientras que para el resto de relaciones (Gasolina-Diesel y Gasolina- GNV) se observa un comportamiento de complementariedad. Ademas desde la elasticidad gasto de la demanda se encontro que la Gasolina y el Diesel se comportan como bienes normales, mientras que el GNV resulta ser un bien inferior.English Abstract: This article presents an Almost Ideal Demand System (AIDS) for different types of fuels in Colombia, focusing specifically on the transport industry. Estimates of price, expenditure and cross elasticities are computed using a Seemingly Unrelated Regressions (SUR) model and based on 10 years observations (2003-2012). Results show that diesel and regular gas behave as inelastic goods while natural gas is more elastic. Also, diesel fuels and natural gas seem to behave as substitutes while there’s a complementary relation among the others (regular gas-Diesel; regular fuels-Natural Gas). Regarding the expenditures elasticities, this paper concludes that regular gas and diesel behave as normal goods while natural gas seems be an inferior type of fuel for the transport sector.)

This paper contributes to empirical literature testing the importance of secure formal legal rights for efficient natural resource exploitation and the promotion of economic growth and development. We use an event study methodology to estimate the market response to a series of six landmark Supreme Court of Canada decisions that reinterpreted aboriginal rights in Canada, providing a shock to the stability and security of the existing entitlements of Canadian resource firms. The paper expands on our earlier study of Canada’s Forest industry to test claims that recognition of aboriginal rights has created uncertainty imposing significant economic costs on Canada’s resource industries. We construct a new data set containing all firms listed on the TSX operating in the Forestry, Mining, and Energy sectors. Using this data set of 2,410 firm-events and corresponding firm level micro-data we provide evidence of the market response to the decisions for the resource sector globally, by industry and across firm characteristics. Our results show that the decisions generated statistically and economically significant effects, and generally support the importance of secure legal rights to the economic performance of resource industries. However, the effects vary in size and direction across decisions, industries, and firm-types.
本文通过实证文献检验了安全的正式法律权利对于有效开发自然资源和促进经济增长和发展的重要性。我们使用事件研究方法来估计市场对加拿大最高法院一系列六个具有里程碑意义的决定的反应,这些决定重新解释了加拿大的土著权利,对加拿大资源公司现有权利的稳定性和安全性造成了冲击。本文扩展了我们之前对加拿大森林工业的研究,以检验承认土著权利造成了不确定性,给加拿大资源工业带来了巨大的经济成本的说法。我们构建了一个新的数据集,其中包含在多伦多证券交易所上市的所有在林业、矿业和能源部门经营的公司。利用这个2410个公司事件的数据集和相应的公司层面的微观数据,我们提供了市场对全球资源部门决策的反应的证据,按行业和跨公司特征。我们的研究结果表明,这些决策产生了统计上和经济上显著的影响,并且总体上支持了确保合法权利对资源行业经济绩效的重要性。然而,在不同的决策、行业和公司类型中,影响的大小和方向各不相同。

This paper empirically analyzes the existence of market power in the global iron ore market during the period 1993-2012 using an innovative Stochastic Frontier Analysis approach introduced by Kumbhakar et al. (2012). In contrast to traditional econometric procedures, this approach allows for the estimation of firm- and time-specific Lerner indices and, therefore, the assessment of the influence of individual firm characteristics on the ability to generate markups. We find that markups on average amount to 20%. Moreover, location and experience are identified to be the most important determinants of the magnitude of firm-specific markups.
本文采用创新的随机前沿分析方法(Kumbhakar et al., 2012)对1993-2012年全球铁矿石市场中市场支配力的存在性进行了实证分析。与传统的计量经济学程序相比,这种方法允许估计企业和特定时间的勒纳指数,因此,评估个别企业特征对产生加价能力的影响。我们发现平均加价达20%。此外,地点和经验被认为是企业特定加价幅度的最重要决定因素。

Taxation and the Asymmetric Adjustment of Selected Retail Energy Prices in the UK 税收与英国选定零售能源价格的不对称调整
Pub Date : 2013-09-04 DOI: 10.2139/ssrn.2278643
Matthew Greenwood‐Nimmo, Y. Shin
This paper investigates the adjustment of the prices of four key petroleum products in the UK following changes in the price of crude oil. We find significant evidence that the pre-tax prices of diesel, kerosene, and gas oil adjust more rapidly in an upward than a downward direction, but that the pre-tax price of unleaded petrol adjusts symmetrically. However, these patterns are obscured at the pump once one accounts for fuel duty and value-added tax, raising the possibility that firms can use the tax system to conceal rent-seeking behaviour.
本文研究了原油价格变化后英国四种主要石油产品价格的调整。我们发现有重要的证据表明,柴油、煤油和汽油的税前价格向上调整的速度比向下调整的速度更快,但无铅汽油的税前价格是对称调整的。然而,一旦考虑到燃油税和增值税,这些模式在加油站就变得模糊了,这增加了企业利用税收制度掩盖寻租行为的可能性。

In this paper we investigate the use of forecast averaging for electricity spot prices. While there is an increasing body of literature on the use of forecast combinations, there is only a small number of applications of these techniques in the area of electricity markets. In this comprehensive empirical study we apply seven averaging and one selection scheme and perform a backtesting analysis on day-ahead electricity prices in three major European and US markets. Our findings support the additional benefit of combining forecasts for deriving more accurate predictions, however, the performance is not uniform across the considered markets. Interestingly, equally weighted pooling of forecasts emerges as a viable robust alternative compared with other schemes that rely on estimated combination weights. Overall, we provide empirical evidence that also for the extremely volatile electricity markets, it is beneficial to combine forecasts from various models for the prediction of day-ahead electricity prices. In addition, we empirically demonstrate that not all forecast combination schemes are recommended.
本文研究了预测平均法在电力现货价格中的应用。虽然关于使用预测组合的文献越来越多,但这些技术在电力市场领域的应用却很少。在这项全面的实证研究中,我们采用七平均和一选择方案,并对欧洲和美国三个主要市场的日前电价进行回测分析。我们的研究结果支持组合预测的额外好处,以获得更准确的预测,然而,在考虑的市场中,表现并不统一。有趣的是,与依赖于估计组合权重的其他方案相比,等加权的预测池成为一种可行的稳健替代方案。总体而言,我们提供的经验证据表明,对于极不稳定的电力市场,将各种模型的预测结合起来预测日前电价是有益的。此外,我们还通过实证证明,并非所有的预测组合方案都是推荐的。

This paper examines the impact of oil revenues on the Iranian economy over the past hundred years, spanning the period 1908-2010. It is shown that although oil has been produced in Iran over a very long period, its importance in the Iranian economy was relatively small up until the early 1960s. It is argued that oil income has been both a blessing and a curse. Oil revenues when managed appropriately are a blessing, but their volatility (which in Iran is much higher than oil price volatility) can have adverse effects on real output, through excessively high and persistent levels of inflation. Lack of appropriate institutions and policy mechanisms which act as shock absorbers in the face of high levels of oil revenue volatility have also become a drag on real output. In order to promote growth, policies should be devised to control inflation; to serve as shock absorbers negating the adverse effects of oil revenue volatility; to reduce rent seeking activities; and to prevent excessive dependence of government finances on oil income.
本文考察了石油收入在过去一百年(1908-2010年)对伊朗经济的影响。这表明,尽管石油已经在伊朗生产了很长一段时间,但直到20世纪60年代初,它在伊朗经济中的重要性相对较小。有人认为,石油收入既是福也是祸。如果管理得当,石油收入是一件好事,但石油收入的波动性(在伊朗,其波动性远高于油价波动性)可能会因过高且持续的通胀水平而对实际产出产生不利影响。面对石油收入的高度波动,缺乏适当的机构和政策机制作为减震器,也拖累了实际产出。为了促进增长,应该制定控制通货膨胀的政策;作为减震器,消除石油收入波动的不利影响;减少寻租活动;防止政府财政过度依赖石油收入。
