the peak of oil production timings and market recognition abstract energy is essential for present societies in particular transportation systems depend on petroleum based fuels that world oil production is set to pass a peak is now a reasonably accepted concept although its date is far from consensual in this work we analyze the true expectations of the oil market participants about the future availability of this fundamental energy source we study the evolution through time of the curves of crude oil futures prices and we conclude that the market participants among them the crude oil producers already expect a near term peak of oil production this agrees with many technical predictions for the date of peak production including our own that point to peak dates around the end of the present decade if this scenario is confirmed it can cause serious social and economical problems because societies will have little time to perform the necessary adjustments

a general equilibrium theory of firm formation based on individual unobservable skills abstract a model of firm formation is built along the lines of knight 1921 contrary to kihlstrom and laffont 1979 the individuals are risk neutral but have different productive efficiencies we suppose that the individuals who are the more efficient workers are also the more efficient entrepreneurs each agent chooses the activity which gives her the larger expected income in equilibrium the more efficient people become entrepreneurs and under a special kind of increasing returns to scale assumption this is also what is implied by efficiency considerations however we show that the equilibrium number of entrepreneurs is always larger than the pareto optimal one a simple uniform lump sum tax on firms together with redistribution of the tax revenue to workers is nevertheless sufficient to restore efficiency

maritime oil freight flows to 2050 delphi perceptions of maritime specialists abstract this paper aims to synthesise maritime specialists perceptions of changing patterns of maritime oil freight flows to 2050 debate spans published maritime oil flows globally diverse drivers of future flows including economic growth shipping market changes and haul lengths a classic delphi study to explore the perceptions of likely trends and flows to 2050 recruited a panel of early career and established maritime specialists many with long term career commitments to this industry underpinned by market volatility and legislative uncertainty the perceptions of both groups coincided and were conservative local sourcing new arctic seaways and fossil fuel intolerance will tend to reduce oil freight work but perceptions of ship re routing to avoid for example emission control areas and piracy would tend to lengthen hauls in advanced industrial nations reducing energy intensities and diminishing social tolerance of fossil fuels imply gradually reducing maritime oil shipments however to achieve radical national commitments to carbon emissions reductions will necessitate specialist education for naturally conservative maritime professionals and vigorous oil import reduction policies to curtail domestic demand for oil shipments

a study on the future of unconventional oil development under different oil price scenarios a system dynamics approach abstract fluctuations in the oil global market has been a critical topic for the world economy so that analyzing and forecasting the conventional oil production rate has been examined by many researchers thoroughly however the dynamics of the market has not been studied systematically with regard to the new emerging competitors namely unconventional oil in this paper the future trend of conventional and unconventional oil production and capacity expansion rates are analyzed using system dynamics approach to do so a supply side modeling approach is utilized while main effective loops are modeled mathematically as follows technological learning and progress long and short term profitability of oil capacity expansion and production and oil proved reserve limitations the proposed model is used to analyze conventional and unconventional oil production shares up to 2025 under different oil price scenarios the results show that conventional oil production rate ranges from 79 995 to 87 044 mb day which is 75 80 percent of total oil production rate while unconventional oil production rate ranges from 19 615 to 28 584 mb day simulation results reveal that unconventional oil can gain a considerable market share in the short run although conventional oil will remain as the major source for the market in the long run

on the environmental economic and budgetary impacts of fossil fuel prices a dynamic general equilibrium analysis of the portuguese case abstract this paper examines the influence of fossil fuel prices on carbon dioxide emissions economic activity and the public sector account in portugal it uses a dynamic general equilibrium model which highlights the mechanisms of endogenous growth and includes a detailed modeling of the public sector fuel price scenarios are based on forecasts by the us department of energy doe us the international energy agency iea oecd and ihs global insight inc the differences in relative fuel prices among the three scenarios lead to substantially different environmental impacts higher fuel prices in the doe us scenario lead to a 10 2 reduction in the policy effort required to meet the eu 2020 emission targets while relative price changes in the iea oecd scenario result in a 19 2 increase in the required policy effort and decreasing fuel prices increase the emissions deficit by 95 9 under the ihs scenario in terms of the long term economic impacts our results suggest a 2 2 reduction in gdp in the doe us scenario and 1 9 in the iea oecd scenario and an increase of 1 4 in the ihs scenario as to the budgetary impact higher fuel prices lead to lower tax revenues which coupled with a reduction in public spending translates to lower public deficits from a methodological perspective our results highlight the importance of the mechanisms of endogenous growth a scenario of higher fuel prices would under exogenous economic growth assumptions result in larger baseline emissions growth substantially smaller economic effects and rather different budgetary effects from a policy perspective our results highlight the importance of fossil fuel prices in defining the level of policy intervention required for compliance with international and domestic climate change legislation

monopolistic competition in the spirit of chamberlin a general model this paper develops a model of large group chamberlinian monopolistic competition in which 1 there are many firms producing differentiated commodities 2 each firm is negligible in that it can ignore its impact on and hence reactions from other firms 3 free entry leads to zero profit of operating firms but 4 each firm faces a downward sloping demand curve the existence of a monopolistically competitive equilibrium is established in a companion paper more particular questions such as whether the market provides too many or too few products are addressed for a special case of the model

this time it s different an inevitable decline in world petroleum production will keep oil product prices high causing military conflicts and shifting wealth and power from democracies to authoritarian regimes abstract there is virtual agreement among geologists that world production of conventional oil will peak at some point in the future oil after all is a finite resource while demand will only grow over time geologists disagree however exactly when the peak will occur using data from the international energy agency the us department of energy the association for the study of peak oil and gas and petroleum industry sources we argue that conventional oil production will reach a worldwide maximum within the next 5 10 years earlier than generally estimated thus leaving a very short time frame within which to plan for conversion to alternative sources of energy unless planning is initiated immediately the united states and other western democracies will see their positions in the global economy undercut as military conflicts over limited energy resources increase and wealth and power are shifted to authoritarian regimes in russia venezuela africa and the middle east

pioneers imitators and generics a simulation model of schumpeterian competition a computer simulation model in the tradition of evolutionary models of technical change is developed in this paper it focuses on r d competition in new product introductions and is based on data for the u s pharmaceutical industry during the 1970s the sensitivity of innovation levels to the rate of generic competition regulatory review time and patent life is examined in the computer simulation experiments these factors are found to have significant long run effects on industry structure and innovation levels

conscientious vs ambivalent consumers do concerns about energy availability and climate change influence consumer behaviour abstract energy availability and climate change are interrelated concerns with economic components they need to be addressed by policy makers and they require changes in energy consumption this study examines whether concerns about energy availability and climate change influence consumer behaviour policy perceptions and beliefs about future energy consumption this question is investigated by analysing data from the eurobarometer 75 4 a comprehensive survey of citizens from all countries of the european union that was conducted in june 2011 n 26 840 the regression results show that people concerned about climate change were significantly more likely to take action to mitigate climate change and to be more favourably disposed towards energy policies and future changes in energy consumption than people who were not concerned about climate change on the other hand people who were concerned about energy availability undertook fewer actions and neither supported energy policies nor believed in future changes in energy consumption this surprising finding raises questions regarding the adequate communication of energy availability and policies to the public in the european union

long term oil prices abstract in this paper we propose a model to estimate and simulate long term oil prices our model is based on properties of demand and supply for oil and it is able to reproduce historical real oil prices well we use the model to estimate and simulate future real oil price scenarios the results show that if we are not able to significantly increase demand elasticity the yearly real oil price change can reach 12 in the years following the peak production level without taking a scarcity rent into account until peak production level is reached the long term real oil price changes stemming from fundamental supply and demand changes are expected to be negative our simulation results based on an expected peak production year of 2020 and a scarcity rent of 3 suggest an expected real crude oil price of 169 bbl in 2040 for comparison the eia outlook predicts a real oil price of 141 bbl for the same year we also provide an on line appendix that allows the readers to change the assumptions underlying our analysis and see the results immediately

modelling long term oil price and extraction with a hubbert approach the lopex model abstract the lopex l ong term o il p rice and ex traction model generates long term scenarios about future world oil supply and corresponding price paths up to the year 2100 in order to determine oil production in non opec countries the model uses hubbert curves hubbert curves reflect the logistic nature of the discovery process and the associated constraint on temporal availability of oil extraction paths and world oil price path are both derived endogenously from opec s intertemporally optimal cartel behaviour thereby opec is faced with both the price dependent production of the non opec competitive fringe and the price dependent world oil demand world oil demand is modelled with a constant price elasticity function and refers to a scenario from acropolis poles lopex results indicate a significant higher oil price from around 2020 onwards compared to the reference scenario and a stagnating market share of maximal 50 to be optimal for opec

the effect of social capital on group loan repayment evidence from field experiments an important question to microfinance is the relevance of existing social capital in target communities to the performance of group lending this research presents evidence from field experiments in south africa and armenia in which subjects participate in trust and microfinance games we present evidence that personal trust between group members and social homogeneity are more important to group loan repayment than general societal trust or acquaintanceship between members we also find some evidence of reciprocity those who have been helped by other group members in the past are more likely to contribute in the future during the past decade exploring the role that social capital plays in economic behaviour has emerged as one of the most fascinating and fertile areas of economic research although precise definitions of social capital are notoriously difficult to pin down one of the early pioneers of the concept coleman 1988 defines social capital as social structure that facilitates certain actions of actors within the structure in his definition coleman specifically highlights the roles of mutual obligation expectations and trustworthiness social norms social sanctions and the transmission of information important studies in both developed and developing countries have analysed the impact of social capital in economic relationships putnam s celebrated work making democracy work civic traditions in modern italy 1993 and bowling alone america s declining social capital 1995 brought attention to the role that social capital plays in the development of the modern state udry s ground breaking 1994 work in nigeria illustrated how the social capital existing in traditional societies may allow for more efficient credit contracts than in developed economies with weaker social

a dynamic oligopoly structural model for the prescription drug market after patent expiration this article incorporates consumer learning and heterogeneity into a dynamic oligopoly model for the prescription drug market in the model both firms and patients need to learn the generic qualities via patients experiences generic firms entry decisions are endogenous but their entry timings depend on a random approval process i apply the model to examine the impact of shortening the expected generic approval time although this policy experiment brings generics to the market sooner it increases a potential entrant s likelihood of entering a crowded market and hence could reduce the total number of generic entrants and consumer welfare

price and variety in the spokes model the spokes model of nonlocalized spatial competition provides a new analytical tool for dierentiated oligopoly and a representation of spatial monopolistic competition an increase in the number of rms leads to lower equilibrium prices when consumers have relatively high product valuations but surprisingly to higher equilibrium prices for in termediate consumer valuations new entry alters consumer and social welfare through price market expansion and matching eects with free entry the market may pro vide too many or too few varieties from a social welfare perspective and the equilibrium price remains above marginal cost even when the number of rms is arbitrarily large

when will fossil fuel reserves be diminished crude oil coal and gas are the main resources for world energy supply the size of fossil fuel reserves and the dilemma that when non renewable energy will be diminished is a fundamental and doubtful question that needs to be answered this paper presents a new formula for calculating when fossil fuel reserves are likely to be depleted and develops an econometrics model to demonstrate the relationship between fossil fuel reserves and some main variables the new formula is modified from the klass model and thus assumes a continuous compound rate and computes fossil fuel reserve depletion times for oil coal and gas of approximately 35 107 and 37 years respectively this means that coal reserves are available up to 2112 and will be the only fossil fuel remaining after 2042 in the econometrics model the main exogenous variables affecting oil coal and gas reserve trends are their consumption and respective prices between 1980 and 2006 the models for oil and gas reserves unexpectedly show a positive and significant relationship with consumption while presenting a negative and significant relationship with price the econometrics model for coal reserves however expectedly illustrates a negative and significant relationship with consumption and a positive and significant relationship with price consequently huge reserves of coal and low level coal prices in comparison to oil and gas make coal one of the main energy substitutions for oil and gas in the future under the assumption of coal as a clean energy source

extraction capacity and the optimal order of extraction the least cost first extraction rule for deposits with different extraction costs previously has been shown to be invalid in general equilibrium this paper demonstrates that this rule also does not hold in partial equilibrium when extraction capacity is limited necessary and sufficient conditions for several surprising extraction orders are presented if extraction from a high cost resource is constrained it may be optimal to begin extraction from a high cost deposit or backstop strictly before extracting from a lower cost deposit if extraction from a low cost resource is limited it may be optimal to exhaust a high cost deposit strictly before the low cost deposit is exhausted or to abandon extraction temporarily from a high cost deposit and then to exhaust it later the analysis demonstrates how extraction constraints affect the order of extraction and shows that certain cost reversals are caused by limited extraction capacity rather than by the general equilibrium definition of extraction costs

oil scarcity what have the past three decades revealed oil shortages have been predicted over the past 30 years in fact oil is more plentiful now in an economic sense than in 1973 the reason for such misconceptions lies mainly in reliance on analytical techniques that do not comprehend oil as an economic commodity

on the optimal order of natural resource use when the capacity of the inexhaustible substitute is limited consider a general equilibrium framework where the marginal cost of extraction from several deposits of an exhaustible resource is constant in terms of an inexhaustible perfect substitute and differs between deposits the instantaneous rate of production form the inexhaustible resource is subject to a capacity constraint

monopolistic competiton on the pyramid the purpose of this paper is to develop a model of monopolistic competition that has a simple locational interpretation and which allows for multifirm competition one of the major weaknesses of the standard circular road model is the fact that it allows only localized competition this creates problems when one wishes to analyze problems of international trade where one often has to work with firms with different production costs one of the major advantages of the pyramid model presented here is that one can easily compute the firms equilibrium profits even when their production costs differ copyright 1991 by blackwell publishing ltd

economic indicators of resource scarcity a critical essay abstract the theoretical arguments of the conceptual and empirical literature on economic indicators of long run resource scarcity are logically flawed if resource allocators were informed of the nature of resource scarcity their behavior and the economic indicators it generates would reflect the scarcity but if they were so informed we could simply ask them if resources were scarce if they are not informed their behavior and economic indicators are as likely to indicate their ignorance as the reality unfortunately there is no way of knowing whether they are informed or not unless we already know whether resources are scarce

who s afraid of atmospheric stabilisation making the link between energy resources and climate change abstract the distribution of fossil fuel reserves and resources between different regions and deposits has strong implications for climate change economics and policy the task of stabilising the atmosphere is intimately linked to the question of long term energy supplies as conventional petroleum reserves deplete notwithstanding debates about the scope for reserve extension through continued exploration and development it suggests a supply side component to complement the consumption orientation of existing climate policies the task is to ensure that investment and innovation moves towards the low carbon frontier instead of the high carbon frontier this also implies that the opec countries have little to fear about the long run impact of climate change policy the priority is to deter development of more carbon intensive unconventional petroleum deposits and technologies and to ensure that the existing trends to diversify power generation sources continue and extend more widely over time supply side constraints will not solve the climate problem in themselves but they make the task a lot easier if the opportunities are taken

a supply model for crude oil and natural gas in the middle east abstract crude oil co and natural gas ng play an important role in the world economy the arab countries acs share 64 of the total oil reserves and 40 of the ng reserves opec 2003 the annual statistical bulletin on the production side acs contribute to 30 and 9 of the world production of co and ng respectively accurate forecast models are needed to do better planning and create less risky business environment in this paper an econometric model is built to capture the behavior of co and ng production in the escwa 1 countries the model is used to forecast future production trends of co and ng and thus provide a powerful tool for researchers planners and investors working in the energy field

global oil gas depletion an overview abstract the world s production of conventional hydrocarbons will soon decline hydrocarbon shortages are inevitable unless radical changes occur in demand or in the supply of non conventional hydrocarbons the details are as follows global conventional oil supply is currently at political risk this is because the sum of conventional oil production from all countries in the world except the five main middle east suppliers is near the maximum set by physical resource limits should middle east suppliers decide to substantially curtail supply the shortfall cannot be replaced by conventional oil from other sources world conventional oil supply will soon be at physical risk the middle east countries have only little spare operational capacity and this will be increasingly called upon as oil production declines elsewhere large investments in middle east production if they occur could raise output but only to a limited extent a partial exception is iraq but even here there would be significant delays before prospects are confirmed and infrastructure is in place if demand is maintained and if large investments in middle east capacity are not made the world will face the prospect of oil shortages in the near term even with large investments resource limits will force middle east production to decline fairly soon and hence also global conventional oil production the date of this resource limited global peak depends on the size of middle east reserves which are poorly known and unreliably reported best estimates put the physical peak of global conventional oil production between 5 and 10 years from now the world contains large quantities of non conventional oil and various oil substitutes but the rapidity of the decline in the production of conventional oil makes it probable that these non conventional sources cannot come on stream fast enough to fully compensate the result will be a sustained global oil shortage for conventional gas the world s original endowment is probably about the same in energy terms as its endowment of conventional oil since less gas has been used so far compared to oil the world will turn increasingly to gas as oil declines but the global peak in conventional gas production is already in sight in perhaps 20 years and hence the global peak of all hydrocarbons oil plus gas is likely to be in about 10 or so years

what will happen to the producer prices for fossil fuels if kyoto is implemented implementation of the kyoto commitments will result in lesser global fossil fuel consumption in 2010 than would occur in the absence of climate policy the paper explores how the consumption change resulting from climate policy implementation could affect the producer prices of fossil fuels the conclusion is that the price impact will be insignificant if the climate policy goals are established credibly and in the near future for that will give rationally behaving fossil fuel producers ample time to adjust production capacity to the changed outlook for future demand it is argued that as long as capacity develops in line with demand prices should remain the same irrespective of the speed and direction of demand change

assessing the date of the global oil peak the need to use 2p reserves combining geological knowledge with proved plus probable 2p oil discovery data indicates that over 60 countries are now past their resource limited peak of conventional oil production the data show that the global peak of conventional oil production is close many analysts who rely only on proved 1p oil reserves data draw a very different conclusion but proved oil reserves contain no information about the true size of discoveries being variously under reported over reported and not reported reliance on 1p data has led to a number of misconceptions including the notion that past oil forecasts were incorrect that oil reserves grow very significantly due to technology gain and that the global supply of oil is ensured provided sufficient investment is forthcoming to turn resources into reserves these misconceptions have been widely held including within academia governments some oil companies and organisations such as the iea in addition to conventional oil the world contains large quantities of non conventional oil most current detailed models show that past the conventional oil peak the non conventional oils are unlikely to come on stream fast enough to offset conventional s decline to determine the extent of future oil supply constraints calculations are required to determine fundamental rate limits for the production of non conventional oils as well as oil from gas coal and biomass and of oil substitution such assessments will need to examine technological readiness and lead times as well as rate constraints on investment pollution and net energy return

views on peak oil and its relation to climate change policy abstract definitions of fossil fuel reserves and resources and assessed stock data are reviewed and clarified semantics explain a large stake of conflict between advocate and critical voices on peak oil from a holistic sources sinks perspective limited carrying capacity of atmospheric sinks not absolute scarcity in oil resources will impose tight constraints on oil use eventually observed peaks in oil production in nearby years will result from politically imposed limits on carbon emissions and not be caused by physical lack of oil resources peak oil belief induces passive climate policy attitudes when suggesting carbon dioxide emissions will peak naturally linked to dwindling oil supplies active policies for reducing emissions and use of fossil fuels will also encompass higher energy end use prices revenues obtained from higher levies on oil use can support financing energy efficiency and renewable energy options but when oil producers charge the higher prices they can pump new oil for many decades postponing peak oil to occur while extending carbon lock in

european climate energy security nexus a model based scenario analysis in this research we provide an overview of the climate security nexus in the european energy sector through a model based analysis of scenarios produced with the poles model the scenarios describe the consequences of different degrees of ghg emission constraint at world level but also for a case where europe adopts an ambitious climate policy while the rest of the world sticks to much more modest abatement policies the analysis shows that under such stringent climate policies europe may benefit of a significant double dividend first in its capacity to develop a new cleaner and climate friendlier energy model and second in a lower vulnerability to potential price or supply shocks on the international energy markets

how oecd countries subsidize oil and natural gas producers and modeling the consequences a review abstract since fossil fuel subsidies entail significant economic fiscal social and environmental costs more and more attention is being paid to phasing out fossil fuel subsidies the oecd has recently completed a report quantifying the amount of both producer and consumer subsidies for their member countries and some work has been implemented on analyzing the effects of consumer subsidy removal however there is hardly any investigation of the consequences of producer subsidies in this paper we focus on oil and gas producer subsidies of oecd countries and their effects first we describe the transfer mechanisms indicated by the oecd report for producer subsidies in order to recommend models to analyze the influence of removing producer subsidies we review upstream oil and gas models and provide a taxonomy for them from them we recommend the most appropriate models for each type of producer subsidy to model upstream decision making our contribution in this paper is to categorize the upstream models we have found compare their main features as well as recommending best in class models for analyzing the effects of each type of upstream producer subsidy

forecasting production of fossil fuel sources in turkey using a comparative regression and arima model this study aims at forecasting the most possible curve for domestic fossil fuel production of turkey to help policy makers to develop policy implications for rapidly growing dependency problem on imported fossil fuels the fossil fuel dependency problem is international in scope and context and turkey is a typical example for emerging energy markets of the developing world we developed a decision support system for forecasting fossil fuel production by applying a regression arima and sarima method to the historical data from 1950 to 2003 in a comparative manner the method integrates each model by using some decision parameters related to goodness of fit and confidence interval behavior of the curve and reserves different forecasting models are proposed for different fossil fuel types the best result is obtained for oil since the reserve classifications used it is much better defined them for the others our findings show that the fossil fuel production peak has already been reached indicating the total fossil fuel production of the country will diminish and theoretically will end in 2038 however production is expected to end in 2019 for hard coal in 2024 for natural gas in 2029 for oil and 2031 for asphaltite the gap between the fossil fuel consumption and production is growing enormously and it reaches in 2030 to approximately twice of what it is in 2000

a variant of the hubbert curve for world oil production forecasts abstract in recent years the economic and political aspects of energy problems have prompted many researchers and analysts to focus their attention on the hubbert peak theory with the aim of forecasting future trends in world oil production in this paper a model that attempts to contribute in this regard is presented it is based on a variant of the well known hubbert curve in addition the sum of multiple hubbert curves two cycles is used to provide a better fit for the historical data on oil production crude and natural gas liquid ngl taking into consideration three possible scenarios for oil reserves this approach allowed us to forecast when peak oil production referring to crude oil and ngl should occur in particular by assuming a range of 2250 3000 gigabarrels gb for ultimately recoverable conventional oil our predictions foresee a peak between 2009 and 2021 at 29 3 32 1 gb year

a closer look at the returns and risks of pharmaceutical r d this study assesses the profitability of researching and developing new chemical entities nces a 36 year investment horizon is projected based on a survey of r d costs and on extensive u s sales data analysis is after taxes the average nce produces a real internal rate of return of 6 1 and a net present value of 76 million in 1976 dollars break even with an opportunity investment in corporate bonds occurs on average after 12 years of sales risk is apparent in that after 24 years of sales some two thirds of nces return no more than the bonds do the median nce not recovering average r d costs produces a negative return alternative assumptions are tested results are highly sensitive to drug price increases and early replacement by generics

an econometrics view of worldwide fossil fuel consumption and the role of us crude oil coal and gas known as fossil fuels play a crucial role in the global economy this paper proposes new econometrics modelling to demonstrate the trend of fossil fuels consumption the main variables affecting consumption trends are world reserves the price of fossil fuels us production and us net imports all variables have been analysed individually for more than half a century the research found that while the consumption of fossil fuels worldwide has increased trends in the us production and net imports have been dependent on the type of fossil fuels most of the us coal and gas production has been for domestic use which is why it does not have a strong influence on worldwide fossil fuel prices moreover the reserves of fossil fuels have not shown any diminution during the last couple of decades and predictions that they were about to run out are not substantiated the nominal and real price of fossil fuels was found to change depending on the type finally estimates of three econometric models for the consumption of fossil fuels from 1949 to 2006 are presented which identify the effects of significant variables

it s the rents stupid the political economy of the resource curse a number of studies suggest that natural resources can have a negative impact on the developing prospects of countries empirical results suggest that political economy models of patronage and rent seeking are central to understanding why such a resource curse arises in other words the resource curse is created by certain resource rents leading to dysfunctional behaviour this article introduces the term impartiality enhancing institutions to structure policy debates by distinguishing conditions under which negative effects of resources can be mitigated moreover it is argued that viewing institutions as an equilibrium outcome has implications for the analysis of institutional change policy initiatives that do not promote the impartiality of institutions nor attend to the underlying interests and incentives keeping a bad institutional equilibrium in place will not help lift the resource curse

logistic growth curve modeling of us energy production and consumption abstract this research used four parameter multi cycle logistic growth curve models on us energy information agency annual data from 1949 to 2015 to produce fixed condition forecasts of us energy production and consumption to 2040 these models and forecasts were used to assess the ability of us energy production sources to meet demand to anticipate production and technology challenges and to make general policy recommendations the logistic fixed condition forecasts indicated the ongoing increases in total us energy production dominated by crude oil and natural gas production will likely peak in 2017 at 95 0 quadrillion quad btu then rapidly decrease through 2040 at 36 2 quad btu while total us energy consumption indicated an ongoing plateau at 98 1 quad btu new growth cycles not evident in the 2015 data will certainly occur mitigating the decline in energy production before 2040 however without adequate foresight and preemptive action it is possible that new production growth would not be adequate to reverse the decline given historical growth trends therefore in addition to continued increases in energy efficiency reductions in use and implementation of carbon management technologies direct effort towards the sustainable development of substantial new growth cycles in all energy production sources through adequate investment of resources should be a priority of the us energy industry policy makers and the public alike

affordability of electric vehicles for a sustainable transport system an economic and environmental analysis abstract this paper compares the economic and environmental benefits of electric and hybrid electric vehicles with that of conventional vehicles without tax credits only the hybrids without plug in incur lifetime total costs equivalent to a conventional vehicle whereas the consumer affordability for all other vehicles is less encouraging and depends on changes in gasoline prices with the provision of federal tax incentives the lifetime total cost for all electric vehicle types that are driven for 120 000 miles over 12 years was found to be generally affordable with no more than 5 higher in lifetime total cost than a conventional vehicle except the hybrid electric plug in equipped with a 35 mile electric driving range results of sensitivity analysis reveal that a greater lifetime driven mileage would promote further overall cost savings even at a greenhouse gas abatement cost as low as 42 per ton our study has demonstrated the importance of an energy policy that includes tax credits to address the inadequacy of cost differentials and consumer affordability the environmental benefits provided by the electric and hybrid electric vehicles should satisfy consumers interest in protecting the environment reducing the dependence on imported fossil fuels and switching from traditional to alternative fuel vehicles

high growth firms in changing competitive environments the us pharmaceutical industry 1963 to 2002 firms across sectors and regions are highly skewed in their ability to engage with innovation and even more skewed in their ability to translate investments in innovation into higher growth recent attention has been placed on the importance of high growth firms hgf for innovation policy our paper explores under what conditions hgf matter for translating r d investments into economic growth and how this depends on firm specific and industry specific factors we use quantile regression techniques to study the r d growth relationship in hgf compared to low growth firms unlike previous studies we pay particular attention to whether this relationship depends on the particular period in the industry s life cycle we focus on the us pharmaceutical industry from 1963 to 2002 and find that the r d growth relationship is sensitive to the changing competitive environment over the industry s history which suggests that innovation policy must focus not only on firm attributes but also competitive structures

innovation and corporate growth in the evolution of the drug industry abstract this work studies the processes of growth of the worlds top 150 pharmaceutical firms on the grounds of an original database which also allows disaggregate analysis at the level of single therapeutical classes and chemical entities our findings show that the industry whose long term evolution is driven by innovation imitation and permanent creation of new markets displays i fat tails in the distribution of growth shocks present at all levels of aggregation with relatively rare big spurs of growth ii a significant autocorrelation of growth rates iii a fall of variance of growth rates with size entirely dependent on corporate diversification patterns in turn plausibly shaped by the competence scope of each firm and iv different lifecycles of diverse types of products and persistent forms of heterogeneity across firms in terms of innovative output which however do not not seem to affect comparative growth performances

a model of market power in customer markets we develop a model for studying dynamic competition in environments with frictions that lead to partial lock in of customers to products the dynamic aspects associated with customer retention and acquisition introduce pricing incentives that do not exist in more traditional static product markets the proposed model while highly stylized maintains certain symmetry properties that allow us to obtain equilibrium existence and uniqueness we then study the comparative statics of the model and derive a closed form relationship between average equilibrium markups and the herfindahl index we illustrate how the model can be used by analyzing mergers in such a dynamic environment

a network city model of spatial competition abstract in this paper we analyze a spatial bertrand oligopoly model called network city model firms compete directly and simultaneously with all other firms in the model we allow for heterogeneous product differentiation heterogeneous constant marginal costs of production and heterogeneous consumer densities we show that the equilibrium is unique and easily computable our model is more general than the existing spatial models and more importantly our model provides a spatial microfoundation for the traditional linear demand functions in a differentiated bertrand oligopoly

alternatives to conventional crude oil when how quickly and market driven abstract we examine the effect of uncertainty concerning remaining supplies of conventional crude oil and its production path on the date alternative fuels will be needed the quantity of alternative fuels needed and how this uncertainty affects firms willingness to provide alternatives in a timely fashion despite large uncertainties about the quantity of oil that remains and its production path the start date for replacements is likely to fall within a twenty two year period that is narrower and earlier than previous estimates the twenty two year window represents considerable uncertainty about the date of the peak and this uncertainty creates an asymmetry in the strategy that maximizes the welfare of firms relative to total social welfare which works against the market s ability to generate a smooth transition from oil to alternative fuels the timeliness of this transition is critical the production paths generated here suggest that 10 million barrels per day or more of alternative fuels will be needed within a decade of the peak in production of conventional crude oil

effective climate energy solutions escape routes and peak oil abstract many well intended climate energy strategies are ineffective in the absence of serious environmental regulation this holds among others for direct support of clean energy voluntary energy conservation technical standards on a limited set of products unilateral stringent carbon pricing and awaiting peak oil as a climate strategy all of these suffer from escape routes that indirectly increase co2 emissions and thus make the original strategy ineffective on the other hand environmental regulation alone may lead to a myopia bias stimulating early dominance of cost effective technologies and a focus on incremental innovations associated with such technologies rather than on radical innovations although adopting a partial viewpoint keeps the analysis simple we urgently need a more inclusive systems perspective on climate solutions this will allow the formulation of an effective climate policy package that addresses the various escape routes

bias in market r d portfolios abstract based on a simple contest model of product innovation we find that in accordance with conventional wisdom and contrary to much of the previous theoretical literature market competition implies an equilibrium level of risk which is too low from society s standpoint the intuition is that the divergence between private and social marginal benefits from rd and this probability is higher for lower risk projects

the end of cheap oil current status and prospects abstract this paper analyses the factors impacting the price of crude oil in order to examine the likely evolution of the oil market and attempts to answer the question whether cheap oil is already a thing of the past based on data made publicly available mostly by the major oil companies it examines the effects of demand and supply the evolution of world oil reserves the trends in new discoveries of new oilfields the evolution of world gross domestic product gdp and the depletion of oil resources the analysis concludes that the world peak in conventional oil production the point beyond which oil production will irreversibly start declining is approaching and will be reached even according to the most optimistic scenarios before 2040 and quite possibly much sooner if the appropriate solutions for substituting crude oil and for conserving the use of energy are not implemented in time then the current upward trend in oil prices is bound to continue

global energy crunch how different parts of the world would react to a peak oil scenario peak oil theory predicts that oil production will soon start a terminal decline most authors imply that no adequate alternate resource and technology will be available to replace oil as the backbone resource of industrial society this article uses historical cases from countries that have gone through a similar experience as the best available analytical strategy to understand what will happen if the predictions of peak oil theorists are right the author is not committed to a particular version of peak oil theory but deems the issue important enough to explore how various parts of the world should be expected to react from the historical record he is able to identify predatory militarism totalitarian retrenchment and socioeconomic adaptation as three possible trajectories

does amd spur intel to innovate more we estimate an equilibrium model of dynamic oligopoly with durable goods and endogenous innovation to examine the effect of competition on innovation in the personal computer microprocessor industry firms make dynamic pricing and investment decisions while consumers make dynamic upgrade decisions anticipating product improvements and price declines consistent with schumpeter we find that the rate of innovation in product quality would be 4 2 percent higher without amd present though higher prices would reduce consumer surplus by 12 billion per year comparative statics illustrate the role of product durability and provide implications of the model for other industries

economic impacts of higher oil and gas prices the role of international trade for germany the analysis concentrates on direct and indirect price increases induced shifts in international trade and structural changes in the oil importing economies the paper at hand asks whether a stabilizing effect via international trade and domestic structural change on the gdp of oil importing countries can be observed if a permanent oil price increase occurs at least for germany structural change from consumer goods to investment goods industry and an improvement of international competitiveness limit negative impacts of increased energy prices analysis is based on the extensive and disaggregated global ginfors model and the detailed inforge model for the german economy

are biofuels an efficient technology for generating sustainable development in oil dependent african nations a macroeconomic assessment of the opportunities and impacts in burkina faso this paper discusses the opportunity for substituting fossil fuels with biofuels in a sahelian country burkina faso bearing in mind the strong link between energy and development and given the country s heavy reliance on imported fossil fuels our study showed that the overall economy private and public companies and basic social services and the state budget could be seriously affected if no viable and local alternative is integrated into the national energy strategy in view of local potential it is recommended that adequate energy resources be sought in order to ensure sustainable socio economic development biofuel opportunities are discussed taking into account technical agronomic and land potentials in this country diversification of energy resources with biofuels would substantially reduce fuel imports in the short term improve overall public finances provide a chance to develop agriculture and provide benefits for the locals however if they are to generate development biofuel projects need to be mindful of food security and economic incentives and should be part of national agricultural strategies

arima forecasting of primary energy demand by fuel in turkey abstract forecasting of energy demand in emerging markets is one of the most important policy tools used by the decision makers all over the world in turkey most of the early studies used include various forms of econometric modeling however since the estimated economic and demographic parameters usually deviate from the realizations time series forecasting appears to give better results in this study we used the autoregressive integrated moving average arima and seasonal arima sarima methods to estimate the future primary energy demand of turkey from 2005 to 2020 the arima forecasting of the total primary energy demand appears to be more reliable than the summation of the individual forecasts the results have shown that the average annual growth rates of individual energy sources and total primary energy will decrease in all cases except wood and animal plant remains which will have negative growth rates the decrease in the rate of energy demand may be interpreted that the energy intensity peak will be achieved in the coming decades another interpretation is that any decrease in energy demand will slow down the economic growth during the forecasted period rates of changes and reserves in the fossil fuels indicate that inter fuel substitution should be made leading to a best mix of the country s energy system based on our findings we proposed some policy recommendations

reliable in the long run petroleum policy and long term oil supplier reliability abstract accelerating oil import dependence in energy consuming nations highlights the importance of having energy supplies at sufficient levels and at stable and reasonable prices consequently it is crucial that oil exporters realize their full production potential current debates on energy security are often focused on short term risks e g sudden disruptions due to wars domestic instability etc however when it comes to assessing oil supplier reliability it is equally important to assess their longer term ability and willingness to deliver oil to the global market this study analyzes the effects of petroleum investment policies on crude oil production trends in 14 major oil producing countries 2000 2010 by focusing on the political institutional frameworks that shape the investment conditions for the upstream oil sector our findings indicate that countries with less favorable oil sector frameworks systematically performed worse than countries with investor friendly and privatized sectors the findings indicate that assessments based on remaining reserves and planned production capacities alone could inflate expectations about future oil supplies in a world where remaining crude reserves are located in countries with unfavorable investment frameworks

the end of peak oil why this topic is still relevant despite recent denials up until recently peak oil was a major discussion point crossing from academic research into mainstream journalism yet it now attracts far less interest this paper evaluates the reasons for this and on going relevance of peak oil considering variations in predictive dates for the phenomenon supported by technological economic and political issues using data from agencies the validity of each position is assessed looking at reserves industrial developments and alternative fuels the complicating issue of demand is also considered the conclusions are that supported by commercial interests an unsubstantiated belief in market and technical solutions and a narrow paradigmatic focus critics of peak oil theory have used unreliable reserve data optimistic assumptions about utilisation of unconventional supplies and unrealistic predictions for alternative energy production to discredit the evidence that the resource limited peak in the world s production of conventional oil has arrived diverting discussion from what should be a serious topic for energy policy how we respond to decreasing supplies of one of our most important energy sources

schumpeterian competition in experimental markets abstract we report on a series of laboratory experiments that capture key elements of research and development r d rivalry the experimental environment has a small number of sellers who compete in terms of pricing and production decisions and in terms of cost reducing r d rewards for innovation depend on the profitability of product market competition the experiments capture a kind of dynamic schumpeterian competition there is a sharp contrast in experimental results between monopolies and four seller competitive markets aggregate r d is higher under competition than under monopoly and prices follow marginal cost reductions much more quickly under competition than under monopoly the paper examines market performance in the experiments and the sources of market performance problems

economic de growth vs steady state economy in recent years the concept of economic de growth decroissance based on the literature of nicolas georgescu roegen e g 1 3 has found a revival in france italy spain and other countries in the popular as well as in the academic literature therein authors took on board georgescu roegens categorical rejection of a steady state economy sse as proposed by herman daly 4 they argue that economic degrowth is the only viable alternative goal to the growing economy this position is challenged in this article and it is concluded that the two concepts are in fact complements economic de growth is not a goal in itself but the rich north s path towards a globally equitable sse moreover the de growth literature can benefit from the strong economic historic roots of the sse and from daly s macroeconomic concepts while in return being able to give lessons about bottom up approaches this would be particularly important for the population issue where daly proposes limited birth licences unfortunately statements on demography are inconsistent and underdeveloped in the de growth literature further it is concluded that most criticisms of the sse are due to a too narrow and technocratic interpretation of the concept instead the sse should be defined as a quasi steady state resting in a dynamic equilibrium and as an unattainable goal which can and probably should be approximated

monopolistic competition in the spirit of chamberlin special results the idea of large group monopolistic competition was first introduced by chamberlin in i 933 although a large literature has developed on this topic since that time it can be argued that few of the models which have been formulated really capture monopolistic competition in chamberlin s sense in a companion paper to this one hart i 983 a model was presented which it was claimed did satisfy the desiderata of large group monopolistic competition specifically the model had the property that i there were many firms producing differentiated commodities 2 each firm was negligible in the sense that it could ignore its impact on and hence reactions from other firms 3 free entry led to zero profit of operating firms but 4 each firm faced a downward sloping demand curve and hence equilibrium price exceeded marginal cost the model of hart i983 was quite general and only such issues as the existence and limiting properties of equilibrium were considered the purpose of the present paper is to analyse a special case of this model in greater detail and to consider in this context the old question of whether too few or too many brands are produced under monopolistic competition before embarking on the analysis however let me briefly indicate why i believe that there is a need for a new model of monopolistic competition further discussion of this may be found in hart i983 in the last few years a sizeable literature has developed on imperfect competition and product differentiation see for example dixit and stiglitz i977 lancaster i979 salop i979 and spence i976 in much of this literature see for example spence i976 markets of fixed finite size are considered where the entry of firms is limited by the existence of set up costs under these conditions only a finite number of firms can operate and hence firms will not be negligible in the sense of 2 in addition due to the integer problem operating firms will generally make strictly positive profits i e 3 is violated models of

the political economy of the pharmaceutical industry e conomicsis a practical science since its inception as an independent discipline it has probed the major policy issues of the day the topics that aroused the interests of its practitioners have generally been those that presented government officials with critical choices the modern literature on the economics of the pharmaceutical industry is no exception this body of material originated with the investigations of the kefauver committee in late 1959 public interest was aroused by the spectacle of confrontation between committee and industry the record made by this committee and its successors grew to tens of thousands of pages as claims and counterclaims were offered regarding industry conduct and performance the primary line of attack concerned pharmaceutical prices and profits the committee demonstrated that prices generally exceeded direct costs of manufacturing for 22 major pharmaceutical firms in 1958 costs of goods sold were merely 32 percent of total sales u s senate report 1961 p 31 the committee argued that this fact alone demonstrated the presence of monopoly power while the substantial difference between revenues and production costs permitted high expenditures on research and development it also paid for even higher selling outlays moreover reported rates of return after taxes during this period on the order of 21 to 22 percent exceeded twice the average for all manufacturing the industry replied that on the contrary prices were low relative to the value afforded consumers and high returns on successful products were required to balance the losses from the large numbers of unsuccessful ones the relevant concept of marginal costs according to the industry position must include the costs of developing and marketing new products and therefore prices were not excessive at all although it admitted earning substantial profits the industry argued that without these returns research outlays would be limited and the number of new drugs reduced the committee countered that little of social value arose from industry research molecules were manipulated and the new drugs that resulted were therapeutically similar to those already on the market indeed it suggested that much
