exploration and extraction in a duopoly exhaustible resource market exploration for an exhaustible natural resource is valuable because it produces information about the resource stock i model a duopoly exhaustible resource industry with imperfect information about stock size as a two period game where each period is made up of an exploration stage and an extraction stage i derive the value of gaining information about stock size prior to committing to an extraction plan both for the exploring firm and for the rival i show that an exploring firm would prefer on average to keep exploration information private but that industry profit is higher when information is made public le processus d e xploration et d extraction dans un marche de ressource naturelle non renouvelable oui il y a un duopole le processus d exploration est utile parce qu il permet de produire des renseignements quant a la taille du stock d une ressource naturelle non renouvelable l auteur examine un modele de duopole dans un jeu a deux p6riodes pour une industrie de ressource naturelle non renouvelable l information est imparfaite quant a la taille du stock de resource et chacune des deux p6riodes a un stage d exploration et un stage d extraction l auteur d6rive la valeur de l information additionnelle qujant a la taille du stock de ressource avant de s etngager dans un plan d extraction a la fois pour l entreprise exploratrice et pour l entreprise rivale on montre que l enterprise exploratrice va pr6f6rer en moyenne garder l information priv6e mais que les profits dans l industrie sont plus 6lev6s quand l information est rendue publique

testing for non jointness in oil and gas exploration a variable profit function approach although the assumption of non joint production is made in a number of areas of economics its empirical validity is seldom examined in this paper we investigate the hypothesis of non jointness in the context of a multiple output production process which utilizes both fixed and variable inputs specifically we test the hypothesis of almost non jointness in the input quantities and prices as well as the hypothesis that inputs and outputs are separable using data on oil and natural gas exploration in alberta canada to facilitate global tests of these hypotheses we estimate a generalized linear generalized leontief variable profit function both with and without the restrictions implied by nonjointness and by separability on the basis of likelihood ratio tests we reject the hypothesis of separability but are unable to reject the non jointness hypothesis based on the maximum likelihood estimates obtained in the non joint case we examine some empirical issues concerning oil and gas exploration activity

an econometric analysis of exploration and extraction of oil in the u k continental shelf this paper develops an econometric model for the analysis of exploration and production policies of price taking suppliers and derives theoretically consistent exploration and output equations for oil which explicitly take account of the oil discovery process and the intertemporal nature of exploration and production decision the model is then applied to an empirical analysis of oil exploration and extraction on the united kingdom continental shelf ukcs over the period 1978 1 1986 4 the analysis explicitly takes account of the available engineering information concerning the pressure dynamics of the petroleum reserves and the geological knowledge pertinent to the discovery process and presents formal statistical tests of the significance of these factors for the explanation of output and exploration in the north sea copyright 1990 by royal economic society

the private and social value of information exploration for exhaustible resources abstract in this paper i develop a model where exploration yields information about the size and location of the stock of an exhaustible resource this information is valuable in two ways first before production takes place reserves must be located through exploration the process of exploration changes unproven reserves which cannot be produced into proven reserves which can one value of exploration then is that it allows total production over time to expand the expansion effect second by exploring in an early time period a producer gains information about the true stock size prior to making a decision about how fast to exploit reserves with better information the extraction rate chosen by the producer will yield higher expected returns from the stock the timing effect i show that the expansion effect is undervalued by a firm relative to a social planner an increase in proven reserves increases production and lowers prices improving consumer welfare the timing effect however can be over or undervalued by a firm relative to a social planner if the exploring firm makes up a relatively small portion of industry and if consumers are not highly risk averse then the firm will overvalue the timing effect as a result firms may not explore some tracts where it is efficient to do so if however a firm finds it valuable to explore a tract it may explore earlier in time than is optimal

opec market failure or power failure abstract the actions of opec and saudi arabia are discussed in terms of their objectives and their technical and social constraints it is concluded 1 that opec does not act as a cartel and 2 that hotelling s rule is not an important feature of pricing or production opec s more specifically saudi arabia s ideal policy is to keep price moderate to try to assure a market for their high reserves over the long run such an action would require heavy investments in capacity including in excess capacity for times of interruption of supply from other countries as in the 1990s and for times of high demand as in the 2000s the action may be inconsistent with other objectives and in any case may be too difficult to achieve

minimum price variations discrete bid ask spreads and quotation sizes exchange minimum price variation regulations create discrete bid ask spreads if the minimum quotable spread exceeds the spread that otherwise would be quoted spreads will be wide and the number of shares offered at the bid and ask may be large a cross sectional discrete spread model is estimated by using intraday stock quotation spread frequencies the results are used to project 1 16 spread usage frequencies given a 1 16 tick projected changes in quotation sizes and in trade volumes are obtained from regression models for stocks priced under 10 the models predict spreads would decrease 38 percent quotation sizes would decrease 16 percent and daily volume would increase 34 percent article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

second best carbon taxation in the global economy the green paradox and carbon leakage revisited acceleration of global warming resulting from a future carbon tax is large if the price elasticities of oil demand are large and that of oil supply is small the fall in the world interest rate weakens this weak green paradox effect especially if intertemporal substitution is weak still social damages from greenhouse gases drop if the fall in oil supply and cumulative emissions is strong enough if the current carbon tax is set too low the second best future carbon tax is set below the first best too to mitigate adverse green paradox effects unilateral second best optimal carbon taxes exceed the first best taxes due to an import tariff component the intertemporal terms of trade effects of the future carbon tax increase current and future tariffs and those of the current tax lower the current tariff finally carbon leakage and globally altruistic and unilateral second best optimal carbon taxes if non kyoto oil importers price carbon too low are analysed in a three country model of the global economy

an experimental investigation of the patterns of international trade this study is the first attempt to create and study a laboratory economy with some of the prominent features of an international economic system the concept of multiple countries in which each country has its own technology preferences and resource endowments is introduced and operationalized the questions posed in the study are related to the law of comparative advantage factor price equalization terms of trade efficiency in production and exchange as guided by multiple and interacting markets and the effects of tariffs on international transactions the study builds on previous work in the experimental study of general equilibrium phenomena

on the optimal resource rent tax total payments to government by a mineral exploration firm which follows bayesian procedures when deciding on exploration plans are shown to vary with the rate of resource rent tax in a two part tax scheme which also includes a competitive auction of the right to explore and mine if the explorer is risk neutral then a zero tax rate maximises government revenue

reserve and land prices with exploration under uncertainty abstract arrow and chang j econom environ manag 9 1 10 1982 analyze an exploration extraction model with uncertainty about the distribution of deposits reserve prices do not exhibit any rising trend when the unexplored land area is big but in order to know what happens when the unexplored area is smaller a probabilistic analysis not yet performed ibid p 10 is required their conjecture of a rising trend at less than the discount rate is confirmed however land prices can be expected to grow faster than reserve prices which helps discriminate between arrow and chang s and other rationalizations of the failure of resource prices to rise at the discount rate

the value of information in resource exploration the interaction of strategic plays and institutional rules abstract several characteristics of information used in resource exploration have led to conjectures that the private market will provide a suboptimal amount of such information a public information provision has been proposed as a remedy both for problems of underproduction and overproduction of private information this paper demonstrates that barring exceptional conditions public provision of information cannot be guaranteed to be a generic solution to the private information overprovision problem in fact an example is developed to demonstrate the possibility that public information exacerbates the private overprovision problem

why trading speed matters a tale of queue rationing under price controls we show that queue rationing under price controls is one driver of high frequency trading uniform tick sizes constrain price competition and create rents for liquidity provision particularly for securities with lower prices the time priority rule allocates rents to high frequency traders hfts because of their speed advantage an increase in relative tick size defined as uniform tick sizes divided by security prices increases the fraction of liquidity provided by hfts but harms liquidity we find that the message to trade ratio is a poor cross sectional proxy for hfts liquidity provision stocks with more liquidity provided by hfts have lower message to trade ratios received september 15 2015 editorial decision october 7 2017 by editor robin greenwood

the contribution of l c gray to the economic theory of exhaustible natural resources and its roots in the history of economic thought abstract the paper opens with an assessment of natural resources economics up to 1913 14 when gray published his two pioneering articles in natural resources economics part i an in depth study of gray weighing his contribution to the microeconomic theory of the mine and the macroeconomic theory of conservation against current literature constitutes the main body of the paper part ii gray and hotelling s contributions to the theory of the mine are compared part iii the paper concludes with a comparison drawn between the author s findings and the scant attention previously paid to gray s contributions to natural resources economics so far as i know this is the first attempt to apply economic theory to this particular problem of conservation h c taylor unpublished letter to c r van hise may 23 1913 a reference to gray s economic possibilities of conservation

the supply of non renewable resources there exists no formal treatment of non renewable resource nrr supply systematically deriving quantity as function of price we establish instantaneous restricted fixed reserves and unrestricted nrr supply functions the supply of a nrr at any date and location not only depends on the local contemporary price of the resource but also on prices at all other dates and locations besides the usual law of supply which characterizes the own price effect cross price effects have their own law they can be decomposed into a substitution effect and a stock compensation effect we show that the substitution effect always dominates a price increase at some point in space and time causes nrr supply to decrease at all other points this new but orthodox supply setting extends to nrrs the partial equilibrium analysis of demand and supply policies thereby it provides a generalization of many results about policy induced changes on nrr markets the properties of restricted and unrestricted supply functions are characterized for hotelling homogeneous as well as ricardian non homogeneous reserves for a single deposit as well as for several deposits that endogenously come into production or cease to be active

home field advantage location decisions of portuguese entrepreneurs an investor s home bias in industrial location decisions may stem from personal factors social capital other non transferable assets and imperfect information about the urban and regional environment this paper explores the distinction between home base and non home location decisions in portugal we reach two important conclusions first the introduction of a variable accounting for prior base of economic activity significantly improves the statistical results second we find that the weighting of distinct location attributes differs between home and non home locations notably non home location choices are strongly governed by agglomeration economies and proximity to major urban centers possibly replicating prior location decisions to economize on search costs the results also enable us to quantify the investor s willingness to opt for a possible home field advantage for example entrepreneurs accept over three times higher labor costs to compete in their resident area of business 2002 elsevier science usa all rights reserved

price controls and the behavior of auction markets an experimental examination price ceilings and price floors are common in all market systems the ancient greeks and hellenistic era egyptians are known to have utilized price controls see h michele p 272 and j p levy p 41 and numerous public policy questions today involve them apparently for as long as price controls have existed their effects have been debated for example diocletion s favorable view of his price ceilings was disputed by the religious philosopher lactantius who charged that the policy led to scarcity and low grade articles p 145

the green paradox of the economics of exhaustible resources abstract the green paradox states that an increasing tax on emissions of carbon dioxide consonant with the expected increase in their marginal damages may induce oil producers to shift their production toward the present and thereby to exacerbate the problem of climatic change the model is based on hotelling models of resource use that do not take the natural and technical features of oil production into account natural features include the decline of production through time according to a decline curve technical features include the requirement to sink investment in productive capacity a model of a profit maximizing firm indicates that if these features are taken into account the prediction of the green paradox is unlikely

exploration and scarcity noting that a suggested measure of natural resource scarcity resource rent is unobservable we show that rent is linked to observable marginal exploration cost a two period model of extraction and exploration reveals that rent is equal to this cost when discovery is certain under risky exploration cost data can be used to bound rent the model also indicates how exploration uncertainty affects the competitive firm s extraction and exploration decisions finally the behavior of u s oil and gas exploration costs suggests that these costs were rising in the postwar era which has different implications for scarcity than indicated by other measures of scarcity

exploration information and aec regulation of the domestic uranium industry abstract for roughly twenty years following the second world war the atomic energy commission was the only purchaser of domestically produced uranium such monopsony power implicitly allowed the atomic energy commission s to regulate the u s uranium industry this paper investigates the atomic energy commission s implicit regulation asking if an efficient allocation of resources was induced the main finding is that undesirably high levels of exploration were induced

oil exploration and perceptions of scarcity the fallacy of early success abstract it has been suggested that oil exploration may lead to false perceptions of decreasing scarcity we perform a simulation of the exploration process using bayesian updating the approach enables us to isolate the information effect on the success rate and also to quantify the subjective expectation of the total resource size the area under exploration consists of a number of regions which may differ in their oil content exploration is performed with the goal to maximize the expected success rate the resulting information about the distribution of oil and the total resource size is assumed public knowledge a number of scenarios with variations in the dimensions of the area under exploration the oil distribution and initial beliefs are considered the results indicate that the information effect on the success rate is significant but brief it might have a considerable impact on price but is an unlikely mechanism behind a long term declining price trend however the information effect on expectations is gradual and persistent since exploration is performed in regions where the expected success rate is the highest the historical success rate will not be representative of the area as a whole an explorer will tend to overestimate the total resource size thereby suggesting an alternative mechanism for false perceptions of decreasing scarcity a mechanism that could be called the fallacy of early success

optimal consumption of a nonrenewable resource with stochastic discoveries and a random environment we present a general model for the optimal consumption of a nonrenewable resource under two kinds of uncertainties one source of uncertainty is in the resource discovery process and the other is in the economic environment that affects resource supply and demand conditions such as exhaustion and development of a substitute the problem is formulated as one of optimally controlling a storage process with markov additive discoveries the optimal value of the resource stock is characterized as the solution of a functional equation and the existence of an optimal consumption policy is established it is shown that in a given environment the optimal consumption rate is increasing and the resource price is decreasing in the level of proven reserves a counterexample is provided to show that better environments may in fact mean higher prices and lower consumption rates finally a variety of examples is given to illustrate the scope and applicability of the general model

stability and competitive equilibrium in trading networks we introduce a model in which agents in a network can trade via bilateral contracts we find that when continuous transfers are allowed and utilities are quasi linear the full substitutability of preferences is sufficient to guarantee the existence of stable outcomes for any underlying network structure furthermore the set of stable outcomes is essentially equivalent to the set of competitive equilibria and all stable outcomes are in the core and are efficient by contrast for any domain of preferences strictly larger than that of full substitutability the existence of stable outcomes and competitive equilibria cannot be guaranteed

the optimal depletion and exploration of a nonrenewable resource in spite of its importance the exploration process has not received much attention in the economics of nonrenewable resources among the researchers who investigated this problem we might mention arrow and chang 1982 deshmukh and pliska 1980 pindyck 1978 1980 and gilbert 1979 1981 for earlier work on this subject we might also mention gaffney 1967 and herfindahl 1974 basically an exploration program is a search for potential deposits whose sizes and locations are both uncertain furthermore exploration technology exhibits a high degree of scale economies our paper represents an attempt to deal with these rather neglected aspects of the exploration process in a model of simultaneous extraction and exploration

antitrust exploration and social optimality in nonrenewable resource markets abstract dependence of electrical utilities on uncertain supplies of uranium apparently has led to an unusual conditioning of uranium demand on the uncertainty of supply which in turn depends on the volume of reserves this paper examines the implications of controlling resource production uncertainty through exploration exploration gives a monopolistic resource supplier another tool in addition to restricting output that can be used to exercise market power exploration however is not subject to antitrust regulation results show that traditional antitrust laws may move such an industry away rather than toward social optimality

a model of mineral taxation and exploration a model of optimal mineral exploration effort is used to determine sufficient conditions for a resource rent tax to be neutral with respect to exploration effort analyses the revenue implications of different rates of resource rent tax firms are assumed to use decision making processes which are implicitly bayesian in determining how much exploratory information to acquire prior to deciding whether or not to extract relates the tax rate and expected revenue from a resource rent tax takes account of the impact of the tax on mineral exploration the likelihood of mining and consequent long run mineral supply

a theory of oil igopoly cournot equilibrium in exhaustible resource markets with fixed supplies the emergence of an effective and powerful cartel in the international petroleum market has stimulated considerable effort among economists to develop models of pricing and supply behavior for this industry 2 this modeling task poses two basic difficulties first as in the standard oligopoly problem one must characterize the behavior of several sellers in a market aware of each other and of their effect on market price second there is here the added difficulty of treating the explicitly intertemporal nature of suppliers decision wherein a limited stock must be optimally allocated over time this paper studies the implications of the simplest non trivial postulates about these two aspects of the problem it is assumed that suppliers are non cooperative cournot nash players each of whom is imagined to select an optimal supply strategy taking as given the strategies of the others moreover it is hypothesized that the feasible strategies are limited to open loop paths chosen at the initial date to maximize the present value of profits in light of the paths of supply which the others have chosen 3 these basic postulates together with a few technical assumptions concerning the structure of resource demand permit one to demonstrate the existence of at least one non cooperative equilibrium concerning thisequilibrium we show that 1 the average and marginal return on resource stocks is inversely related to the size of a player s initial endowment 2 aggregate production decreases over time until all stocks are exhausted while firms with smaller stocks exhaust their supplies no later than firms with larger stocks do 3 the present value of price net of extraction cost declines over time 4 industry production maximizes a weighted average of intertemporal consumer s surplus and producers profits

commodity price volatility with endogenous natural resources abstract natural resource reserves are exogenous in models of small commodity exporters changes in the stock of reserves play no role in the macroeconomy including in business cycle volatility trade dynamics or exchange rate volatility we consider richer supply dynamics and model exploration and depletion we show that an endogenous supply of reserves is important for capturing the stylised facts associated with commodity price shocks including a commodity currency the crowding out of non commodity activity dutch disease and a volatile business cycle we also consider how exploration and depletion affect the ranking of optimal monetary and taxation policies when natural resource reserves are held fixed monetary policy is an efficient tool for stabilising the effects of commodity price shocks however when exploration and depletion are accounted for using interest rates to stabilise the effects of commodity price changes becomes inefficient using taxes on the resource sector specifically an ad valorem royalty remains efficient

on the nonexistence of market equilibria in exhaustible resource markets with decreasing costs this paper examines the existence of competitive equilibria in markets for exhaustible resources where there are initial economies of scale in either the extraction of the resource or the utilization of the resource as an input in production in such instances which are fairly common we find that the classic hotelling rule for competitive extraction does not apply since competitive price equilibria generally do not exist this is in marked contrast to static markets where the usual textbook example of firms with u shaped average cost curves is not inconsistent with the existence of competitive equilibria furthermore oligopolistic market equilibria in which resource firms act as nash producers may also fail to exist when there are returns to scale in production

grade selection under uncertainty least cost last and other anomalies abstract grade selection rules for heterogeneous resource deposits with increasing marginal extraction costs are derived it is shown that contrary to the conventional wisdom it can be optimal to extract the least cost deposits last there are a number of rules that are compatible with dynamic profit maximization under certainty nevertheless none explains empirical regularities in actual extraction patterns when uncertainty about future price is introduced however the theoretical model conforms closely not only to observed grade selection patterns but also to observed mineral industry price paths

vertical versus horizontal tax externalities an empirical test abstract we study taxation externalities in federations of benevolent governments where different hierarchical government levels tax the same base one can observe two types of externalities a horizontal externality working among governments of the same level and leading to tax rates that are too low compared to the social optimum and a vertical externality working between different levels of government and leading to suboptimally high tax rates building on the model of keen and kotsogiannis keen michael j kotsogiannis christos 2002 does federalism lead to excessively high taxes american economic review 92 1 363 370 we derive a discriminating hypothesis to distinguish vertical and horizontal tax externalities based on measurable variables this test is applied to a panel data set on local taxes in a sample of swiss municipalities that feature direct democratic fiscal decision making so as to maximize the correspondence with the benevolent governments of the theory we find that vertical externalities dominate they are thus an observed empirical phenomenon as well as a notable extension to the theory of tax competition

a martingale characterization of the price of a nonrenewable resource with decisions involving uncertainty abstract this paper presents a general model of nonrenewable resource consumption and exploration decisions involving uncertainty about the time of occurrence of an event such as exhaustion stock discovery or a substitute development the resulting price process is characterized in terms of necessary and sufficient conditions under which the price is expected to rise at a rate equal to greater than or less than the discount rate the general model is illustrated and the price process and the optimal decisions are characterized by examining the three types of uncertainty indicated above

exploration and exhaustible resources the microfoundations of aggregate models the appropriate specifications for aggregate extraction and exploration cost functions are derived from a disaggregate model of the search for low cost deposits of an exhaustible resource the common practice of combining the no discovery extraction cost function with exploration is shown to result in a misspecified model for which the total cost of extracting the resource is not well defined the widely accepted prediction that the anticipated discovery of low cost deposits results in a u shaped price path appears to be an artifact of this misspecification for the authors properly specified cost functions the predicted resource price always rises copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

trade execution costs and market quality after decimalization this study assesses trade execution costs and market quality for nyse and nasdaq stocks before and after the 2001 change to decimal pricing several theoretical predictions are confirmed quoted bid ask spreads declined substantially on each market with the largest declines for heavily traded stocks the percentage of shares receiving price improvement increased on the nyse but not on nasdaq however those trades completed at prices within or outside the quotes were improved or disimproved by smaller amounts after decimalization and trades completed outside the quotes saw the largest reductions in trade execution costs as a class effective bid ask spreads as a percentage of share price arguably the most relevant measure of execution costs for smaller trades averaged 0 33 on a volume weighted basis after decimalization for both nyse and nasdaq stocks there is no evidence of systematic intraday reversals of quote changes on either market as would be expected if decimalization had damaged liquidity supply

sectoral supply of minerals of varying quality in this sectoral model of mineral production investment in capacity and variation in orebody grade and volume help explain some stylized facts more than one grade of ore may be exploited simultaneously mine exhaustion but not necessarily entry occurs in declining order of grade the price may rise or fall but is likely to fall initially young industry and must eventually rise at less than the interest rate unless demand expands rapidly these trends exhibit fluctuations due to entry and exhaustion of deposits resource price cyclicality is reinforced because mines keep producing at capacity when the price is falling

ambiguous changes in product quality economic goods are frequently sold according to a price per unit quantity where the quantity characteristic does not measure all the economically important characteristics of the good milk is sold by the quart automobiles rented by the mile physicians services bought by the visit and tennis lessons by the hour in all cases heterogeneous units are available in the market and the price per unit quantity depends upon the amount of the unpriced characteristic contained in each unit the per quart price of milk depends upon the butterfat content the mileage costs of automobile rentals on the cars make and the price per unit time for personal services on the providers skill and training the common distinction made between these variants of the same good is that they differ in quality where quality refers to the amounts of the unpriced attributes contained in each unit of the priced attribute thus milk is packaged according to the attribute milk liquid and the quality of milk refers to the ratio of butterfat per unit of liquid 2 this paper considers some of the unique aspects of the economics of supply and demand under this situation where products contain at least two desired attributes only one of which is quantified and measured prior to purchase product quality is here defined by the ratio of the second quality attribute per unit of the measured quantity attribute 3 this simple specification of quality allows a direct link between standard economic models of related products and the economics of variable product quality previous analyses which treat quality simply as a shift parameter in the demand function are shown to obscure the actual subtleties of supply and demand with variable endogenous quality 4 the paper proceeds by first examining the efficient quality and quantity and the competitive equilibrium the market equilibrium under monopoly is then contrasted in the second section the general theme of the

tick size price grids and market performance stable matches as a model of market dynamics and equilibrium abstract the tick size in a financial market is the minimum allowable difference between ask and bid prices by the rules of each exchange no transactions can occur within the tick interval the impact of tick size is an ongoing controversy which we study by experimental methods whose simplicity helps distinguish among competing models of complex real world securities markets we observe patterns predicted by a matching cooperative game model because a price grid interferes with a competitive equilibrium and restrictions on order flow interfere with information aggregation the matching model provides predictions when the competitive model cannot although their predictions are the same when a competitive equilibrium does exist our experiments examine stable allocations average prices timing of order flow information flow and price dynamics larger tick size invites more speculation which in turn increases liquidity however increased speculation leads to inefficient trades that otherwise would not have occurred

assessing the effects of local taxation using microgeographic data we study the impact of local taxation on the location and growth of firms our empirical methodology pairs establishments across jurisdictional boundaries to estimate the impact of taxation our approach improves on existing work as it corrects for unobserved establishment heterogeneity for unobserved time varying site specific effects and for the endogeneity of local taxation applied to data for english manufacturing establishments we find that local taxation has a negative impact on employment growth but no effect on entry

penny pricing and the components of spread and depth changes abstract recent studies show that decimal pricing led to significant reductions in the spread and depth on the nyse in this paper we examine how the observed changes in the spread and depth can be attributed to different factors we show that stocks with higher proportions of one tick spreads and odd sixteenth quotes and more frequent trading before decimalization experienced larger declines in the spread and depth afterwards we interpret this result as evidence of reduced binding constraints and increased price competition under decimal pricing we also find that decimal pricing led to nontrivial changes in select stock attributes and that these changes exerted an additional impact on spreads and depths our results suggest that sub penny pricing may further reduce the spreads of high volume low risk or low price stocks

estimating potential social losses from market failure oil exploration in alberta this article presents estimates of the potential social losses caused by market failure in oil exploration in the rainbow zama region of alberta we construct models that predict exploratory drilling for noncooperative nash equilibrium with and without taxes and for the social optimum in the absence of appropriate property rights or taxes estimated losses are of the order of 80 of potential rents with taxes estimated losses are of the order of 30 we show that actual drilling resembles that predicted by the noncooperative model with taxes rather than by the optimal model this indicates that the land tenure system in alberta did not effectively ameliorate the market failure not eliminated by taxation

market size and tax competition abstract with international externalities different country sizes imperfect competition and trade costs tax competition for mobile firms is efficiency enhancing with respect to the free market outcome under both scenarios the resulting inefficiencies in international specialization and trade flows vanish when trade costs are low enough otherwise only international tax coordination can implement the efficient spatial distribution of firms

exploration information and regulation in an exhaustible mineral industry abstract the paper presents a model of exploration and production in an uncertain environment exploration provides a by product of information that helps predict future finds more accurately when this information is not equally valued at the margin by society and industry socially inefficient levels of exploration are chosen by industry in this event government intervention may be warranted a regulator could control future prices to encourage industry to select socially preferred levels of production and exploration alternatively by making public varying amounts of exploration information incentives to industry could be adjusted conditions where such regulation might yield sufficient gains to society to offset regulatory costs are considered

extraction costs and the economics of nonrenewable resources the study questions the fundamental assumption of the standard aggregate exploration extraction model of nonrenewable resources that extraction costs and the level of reserves are inversely related it also raises questions about the model s conclusions regarding exploration incentives and the valuation of reserves an empirically tested disaggregate model is presented that suggests that exploration activity occurs from firms attempting to balance marginal extraction plus user costs at the intensive and extensive margins exploration is carried out until the marginal discovery cost of a deposit equals its present asset value and a u shaped price path is indicated

behaviour of non renewable natural resource firms under uncertainty optimizing or ad hoc abstract this paper tests the assumption of optimizing behaviour by natural resource firms in the framework of an intertemporal model of non renewable resource development and production using data from the petroleum industry it is argued that the presence of geological and price uncertainty presents a situation in which standard objections to non optimizing behaviour may not hold as an alternative it is proposed that firms use an ad hoc rule of thumb to update decisions as the values of variables change econometric results support ad hoc behaviour as opposed to intertemporal profit maximization

do agglomeration economies reduce the sensitivity of firm location to tax differentials recent theoretical work in economic geography has shown that agglomeration forces can mitigate race to the bottom tax competition by partly or fully offsetting firms sensitivity to tax differentials we test this proposition using data on firm births across swiss municipalities we find that corporate taxes deter firm births less in more spatially concentrated sectors firms in sectors with an agglomeration intensity in the top quintile are less than half as responsive to differences in corporate tax burdens as firms in sectors with an agglomeration intensity in the bottom quintile hence agglomeration economies do appear to attenuate the impact of tax differentials on firms location choices

optimal exploration for and exploitation of heterogeneous mineral deposits abstract we model exploration for and production from a multiple deposit nonrenewable resource exploration is viewed as a bayesian process involving learning about undiscovered reserves and is undertaken both to improve the quality of and to replenish known reserves known reserves are not physically defined but depend on the realizations of discrete episodes of exploration elsewhere and on decisions at each instant about the margin between ore to be mined and low grade material to be rejected the appropriate measure of resource scarcity the sustainable level of the contribution of the resource and the treatment of depletion in the national accounts are considered

asymmetric information information externalities and efficiency the case of oil exploration in this article we examine the efect of private information and information externalities on the ex post eficiency of investment in oil exploration we show that too much drilling tends to occur ifjirms believe that the area is likely to contain a sizeable pool of oil and too little drilling occurs if the opposite is true bargaining with well defined property rights to the information externality can eliminate underinvestment but overinvestment remains a problem because firms have an incentive not to disclose their private information

the economics of exploration for non renewable resources abstract the literature on exploration for non renewable resources is surveyed following a brief synopsis in section 2 section 3 focuses on issues related to the world market for resources section 4 considers more microeconomic supply related issues linked to the exploration of the small region or play section 5 turns to the small but growing literature on exploration as a learning process related to r d the latter sections pay particular attention to empirical and policy aspects

optimal pricing use and exploration of uncertain natural resource stocks abstract units of natural resources to be called mines are assumed distributed over an unexplored territory according to a poisson process in space at any moment total reserves and unexplored land are given society can determine the rate of consumption and the rate of exploration reserves are drawn down by consumption and increased by discoveries made during exploration the amount of unexplored land is decreased by exploration at any moment the payoff of society is a concave function of consumption less a linear function of exploration with future payoffs discounted optimal policies are considered and in particular it is shown for a large amount of unexplored land the shadow prices of reserves and of unexplored land move in random cycles but show only a slight upward tread thereby casting some light on the failure of mineral prices to rise at the market rate of interest

the location choices of foreign investors a district level analysis in india this paper analyzes the determinants of the location choices made by foreign investors at the district level in india to gauge the relative importance of economic geography factors local business conditions and the presence of previous foreign investors we employ a discretechoice model and poisson regressions to control for the potential violation of the assumption of independence of irrelevant alternatives our sample includes about 19 500 foreign investment projects approved in 447 districts from 1991 2005 we find that foreign investors strongly prefer locations where other foreign investors are they are also attracted to industrially diverse locations and those with better infrastructure we conclude that the concentration of fdi in a few locations could fuel regional divergence in post reform india

international capital markets oil producers and the green paradox a rapidly rising carbon tax leads to faster extraction of fossil fuels and accelerates global warming we analyze how general equilibrium effects operating through the international capital market affect this green paradox in a two region two period world with identical homothetic preferences and without investment the global interest rate falls and the green paradox weakens with investment or a relatively more impatient oil importing region the green paradox may be strengthened because the future oil demand function shifts downward or because the interest rate rises if the oil importing region is very much more patient than the oil exporting region the green paradox may be reversed but in our calibrated model the effects are tiny with exploration and endogenous initial oil reserves a future carbon tax lowers cumulative oil extraction in partial equilibrium if the boost to current oil extraction is weakened strengthened or reversed in general equilibrium so is the fall in cumulative extraction a partial and general equilibrium welfare analysis of a future carbon tax both for full and partial exhaustion is given the effects of stock dependent extraction costs are separately discussed in an appendix

understanding price controls and nonprice competition with matching theory we develop a quality competition model to understand how price controls affect market outcomes in buyer seller markets with discrete goods of varying quality while competitive equilibria do not necessarily exist in such markets when price controls are imposed we show that stable outcomes do exist and characterize the set of stable outcomes in the presence of price restrictions in particular we show that price controls induce non price competition price floors induce the trade of inefficiently high quality goods while price ceilings induce the trade of inefficiently low quality goods

information and exhaustible resources a bayesian analysis abstract we develop a continuous time bayesian model of investment in information about an exhaustible resource because of the way that information affects expectations the deterministic hotelling rule turns out to be more appropriate as a description of how resource owners forecast the value of their stocks than as a predictor of observed changes in the resource price a flow of information generates both unanticipated changes in expectations which cause the mean rate of change in the resource price to deviate systematically from the deterministic hotelling rule and reductions in uncertainty which do not affect the hotelling prediction

price controls non price quality competition and the nonexistence of competitive equilibrium we investigate how price ceilings and floors affect outcomes in continuous time double auction markets with discrete goods and multiple qualities when price controls exist the existence of competitive equilibria is no longer guaranteed hence we investigate the nature of non price competition and how markets might evolve in its presence we develop a quality competition model based on matching theory equilibria of the quality competition model always exist in such price constrained markets moreover they naturally correspond to competitive equilibria when competitive equilibria exist additionally we characterize the set of equilibria of the quality competition model in the presence of price restrictions in a series of experiments we find that market outcomes closely conform to the predictions of the model in particular price controls induce non price competition between agents both in theory and in the experimental environment market behaviors result in allocations close to the predictions of the model

spatially variable taxation and resource extraction the impact of state oil taxes on drilling in the us abstract we estimate the responsiveness of nonrenewable resource firms to taxes on output using spatially explicit data from the oil sector in the united states using a model of resource firm capital allocation over space we show that responses to spatially varying taxes differ from responses to equivalent changes in the common output price a larger response to tax rates occurs because the tax change only affects the returns to drilling in a single state whereas a price change affects both the returns to drilling in a state and the opportunity cost of not drilling in other states econometrically we estimate the effect of severance taxes on oil drilling we find that the response to a one dollar increase in tax per unit of production has an effect at least eight times as large as the effect of an equivalent decrease in output price the tax response is inelastic implying that an increase in state tax rate would increase revenue we do not find evidence of spillovers between states in the local areas near state borders

the impact of corporate and personal income taxes on the location of firms and on employment some panel evidence for the swiss cantons abstract the impact of corporate income taxes on location decisions of firms is widely debated in the tax competition literature tax rate differences across jurisdictions may lead to distortions of firms investment decisions empirical evidence on tax induced relocation and subsequent economic development in the us and europe is still inconclusive much the same applies to switzerland while there is some evidence on personal income tax competition between swiss cantons evidence on the impact of intercantonal corporate income tax differences on the location of business within switzerland is missing in this paper we present econometric evidence on the influence of corporate and personal income taxes on the regional distribution of firms in 1981 and 1991 and on cantonal employment using a panel data set of the 26 swiss cantons from 1985 to 1997 the results show that corporate and personal income taxes deter firms to locate in a canton and subsequently reduce cantonal employment

firm location decisions regional grants and agglomeration externalities we examine whether discretionary government grants influence where domestic and multinational firms locate new plants and how the presence of agglomeration externalities interacts with these policy instruments we find that a region s existing industrial structure has an effect on the location of new entrants grants do have a small effect in attracting plants to specific geographic areas but importantly we find that firms are less responsive to government subsidies in areas where there are fewer existing plants in their industry this suggests that these subsidies are less effective in influencing firms location decisions in the face of countervailing co location benefits
