the fisher hypothesis and the forecastability and persistence of inflation abstract for the period 1860 to 1939 the simple correlation of the u s commercial paper rate with the contemporaneous inflation rate is 0 17 the corresponding correlation for the period 1950 to 1979 is 0 71 this paper attributes this apparent change in the fisher relation to differences in the stochastic process of inflation rather than a change in any structural relationship between interest rates and expected inflation contrary to recent claims in the literature there is little evidence of inflation non neutrality in data from the pre world war i period

nonrenewable resource scarcity nonrenewable resource theory often is summarized by hotelling s rule this paper reviews theoretical extensions and empirical investigations of resource extraction models observed data are often inconsistent with the hotelling rule suggesting that other characteristics of nonrenewable resource supply including exploration heterogeneous ore quality technological progress and capital investment are important determinants of the dynamic behavior of resource prices given the persistent recurrence of concern about nonrenewable resource scarcity measures of nonrenewable resource scarcity and the empirical evidence for the time trends of those measures are reviewed finally the implications of nonrenewable resource scarcity for economic growth are examined

the role of market expectations in commodity price dynamics evidence from oil data abstract this paper examines the contribution of market expectations to commodity price dynamics it proposes a dynamic competitive storage framework with an explicit expectations shock along with concurrent shocks to study the commodity price movements this allows for a refined analysis of the expectations effect on price and inventory and the estimation of the expectations applied to the world crude oil market it finds that the contribution of market expectations to the crude oil spot price movements is limited from 1987 to 2014

natural resource prices will they ever turn up abstract natural resource theory predicts that natural resource rents should increase over time however technical progress in resource extraction environmental constraints or great natural abundance could result in stagnant or declining product prices thus there is no theoretical reason to believe that product prices will rise in the near future the prediction of product prices by time series methods is shown to depend critically upon whether the series are modeled as difference or trend stationary dickey fuller and lagrange multiplier tests are used to show that the series are difference stationary long and short sample series are tested trend stationary modeling strongly predicts rising resource prices the result from difference stationary modeling is that there is only a weak supposition that natural resource prices will rise

the price elasticity of u s shale oil reserves we formulate a model of shale oil development that identifies how much of the u s resource base is likely to be economically viable at various price levels and what share of potential drilling sites are likely to be exploited the analysis is driven by the lognormal variability in productivity of individual wells we find the volume of reserves to be highly inelastic with respect to price the number of viable drilling sites is less inelastic which may explain why reserve additions and production fell much less than drilling activity during the recent industry slump

the purchasing power of money and nominal interest rates a re examination while it has been known for some time that under uncertainty the original version of the fisher hypothesis is not precisely correct empirical researchers have largely ignored this fact such an omission has possibly resulted in erroneous conclusions concerning other hypotheses most notably the impact of prices on the real economy this paper clarifies some of the previous interpretations of the existing empirical literature and provides a theoretical version of the relation between prices and interest rates empirical tests based on both the livingston survey data and data from time series forecasting models provide support for the fisher effect and the hypothesis that only covariance risk is priced in the treasury bill market one of the basic hypotheses concerning rationality in financial markets is based on statements generally attributed to fisher 18 fisher argued that the nominal or money rate of return on an asset should compensate an investor for his or her required real rate of return and changes in the purchasing power of money for the uncertainty case fisher replaced known purchasing power changes with the expected inflation rate whereas the fisher relationship under certainty is well defined his basic theorem under uncertainty is not precise as fama 15 has argued it is changes in the purchasing power of money not the inflation rate that should concern investors under uncertainty the expected value of one is not by jensen s inequality the inverse of the expected value of the other moreover fama and farber 16 grauer and litzenberger 20 and benninga and protopapadakis 3 have shown that when investors are risk averse the fisher relationship will generally not hold even after adjustment has been made for the distinction between purchasing power changes and the inflation rate in particular these authors show that an adjustment must be made for the fact that the real rate of return on nominal bonds is random while these issues have been discussed in the theoretical literature they have largely been ignored in the empirical work on this topic given the fact that nominal rates do not seem to adjust as rapidly to price changes as fisher hypothesized numerous empirical researchers have expanded the basic fisher model in an attempt to explain this empirical anomaly these extensions include the incorporation of a inflation rate variability and the growth in real output

the effects of oil supply and demand shocks on u s consumer sentiment this paper investigates how the university of michigan s index of consumer sentiment responds to oil price shocks while oil supply shocks play only a limited role the effect of aggregate demand shocks is positive for the first few months and negative thereafter a typical other oil demand shock has a significant negative impact for up to 2 years by studying the responses of individual survey questions we find that expectations of future inflation and a change in real household income as well as perceived vehicle and house buying conditions are the main transmission channels of oil supply and demand shocks

is hotelling s rule relevant to domestic oil production a model of oil supply from known reserves is developed to incorporate geological and engineering principles in the oil field operator s decision problem oil production from existing wells within an oil field is isolated from the drilling of new wells the geo engineering

the risk of policy tipping and stranded carbon assets if global warming is to stay below 2 c there are four risks of assets stranding first substantial fossil fuel reserves will be stranded at the end of the fossil era second this is true for exploration capital too third unanticipated changes in present or expected climate policy cause discrete jumps in today s valuation of physical and natural capital fourth if timing and intensity of climate policy are uncertain revaluation of assets occurs as uncertainty about future climate policy is resolved to highlight these four effects we use an analytical model of investment in exploration capital with intertemporal adjustment costs reserves depletion and market capitalization and calibrate it to the global oil and gas industry climate policy implements a carbon budget commensurate with 2 c peak warming and we allow for immediate or delayed carbon taxes and renewable subsidies the social welfare ranking of these instruments is inverse to that of the oil and gas industry which prefers renewable subsidy and delaying taxes for as long as possible we also pay attention to how the legislative risk of tipping into policy action affects the timing of the end of the fossil era the profitability of existing capital and green paradox effects

the green paradox and budgetary institutions abstract we examine oil production strategies in response to the rise of alternative energy in context of saudi arabia and the united states in a unified simultaneous equation model sem over the period 1976 2015 we investigate the extent to which budget balance behaviour explains the nature of oil production strategies we find that green regulations have a positive impact on u s oil production while an inverse relationship holds for saudi arabia we argue that the nature of budgetary institutions prevents saudi arabia from following a profit maximising behaviour saudi arabia is incentivised to ensure political cohesion through adopting a procyclical fiscal policy rather regulators seem incentivised to channel surplus towards individuals to gain popularity in the united states a thriving shale oil industry is a plausible rationale for u s production strategies also known as a weak green paradox this is problematic for climate change initiatives to reduce global emissions climate experts may wish to pay more attention to the supply side of oil markets when designing decarbonisation plans the results challenge conventional wisdom of the green paradox neglecting the role of incentive structure between different types of oil producers

hearts and spades paradigms of household economics abstract this paper explains why the feminist critique of inequalities within the family poses a serious challenge to conventional economic theories of the household but it also discusses those aspects of both neoclassical and marxian theory that are useful to an analysis of conflict within the family arguing that the bargaining power models being developed by some neoclassical theorist are complementary to marxist influenced structural accounts

what drives commodity price booms and busts abstract we provide evidence on the dynamic effects of aggregate commodity demand shocks commodity supply shocks and storage demand or other commodity specific demand shocks on real commodity prices we analyze a new data set of price and production levels for 12 agricultural goods metals and soft commodities from 1870 to 2013 we establish that commodity demand shocks strongly dominate commodity supply shocks in driving prices over a broad set of commodities and over a long period of time while commodity demand shocks have gained importance over time commodity supply shocks have become less relevant

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

program interventions intrahousehold distribution and the welfare of individuals modelling household behavior abstract in this essay the implications for the intrahousehold distribution of resources derived from economic models of household behavior that treat the household as maximizing a single welfare function are reviewed particular attention is paid to the within family allocation of time and food and to the effects of these resources on the schooling earnings and health status of individuals as they are affected by direct food intervention and female employment schemes and price altering policies empirical applications are provided from data sets from india indonesia and the philippines to illustrate the power and limitations of such models for illuminating household interventions and for placing restrictions on data

natural resource economics under the rule of hotelling abstract natural resource stocks held in situ are physical assets equilibrium in the assets market requires that their rates of return be such that their owners are just willing to hold on to them rather than invest elsewhere i discuss a number of factors relating to the evolution of extraction costs to the durability of the resource to market structure and to uncertainty that are important in correctly characterizing the rate of return on holding exhaustible natural resource stocks the emphasis is put on how those factors can potentially help bridge the gap between the basic hotelling s rule of natural resource exploitation and the historical behaviour of the flow price of a number of resources i also highlight some theoretical and empirical issues that need further attention

the impact of household income on child labour in urban turkey abstract the aim of this study is to investigate the determinants of child labour in urban turkey with a special reference to low household income or poverty as one of its root causes studies done elsewhere have produced mixed results which necessitate the relationship to be studied at country level the data from urban turkey indicate that children from poorer families stand at a higher risk of employment this finding is confirmed using various measures of household material well being simulation results have further pointed out that current interventions are not likely to produce a sizeable impact on the child labour problem

on low frequency estimates of long run relationships in macroeconomics abstract a number of recent studies have attempted to test propositions concerning long run economic relationships by means of frequency domain time series techniques that concentrate attention on low frequency comovements of variables the present paper emphasizes that many of these propositions involve expectational relationships that are not inherently related to specific frequencies or periodicities thus the association of low frequency time series test statistics with long run economic propositions is not generally warranted that such an association can be misleading is demonstrated by analysis of examples taken from notable papers by geweke lucas and summers

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

does drawing down the us strategic petroleum reserve help stabilize oil prices we study the effects of releases from the us strategic petroleum reserve spr within the context of fully specified models of the global oil market that explicitly allow for storage demand as well as unanticipated changes in the spr we show that historically spr policy interventions defined as sequences of exogenous spr shocks during selected periods have helped stabilize the price of oil their effect on the price of oil however has been modest for example the cumulative effect of the spr releases after the invasion of kuwait in 1990 was a reduction of 2 per barrel in the real price of oil after 7 months whereas emergency drawdowns tend to lower the real price of oil we find that exchanges tend to raise the real price of oil in the long run we also provide a detailed analysis of the benefits of the 2018 white house proposal to sell off half of the spr within the next decade we show that the expected fiscal benefits of this plan are somewhat higher than the revenue of 16 6 billion dollars projected by the white house

what do we learn from the price of crude oil futures summary despite their widespread use as predictors of the spot price of oil oil futures prices tend to be less accurate in the mean squared prediction error sense than no change forecasts this result is driven by the variability of the futures price about the spot price as captured by the oil futures spread this variability can be explained by the marginal convenience yield of oil inventories using a two country multi period general equilibrium model of the spot and futures markets for crude oil we show that increased uncertainty about future oil supply shortfalls under plausible assumptions causes the spread to decline increased uncertainty also causes precautionary demand for oil to increase resulting in an immediate increase in the real spot price thus the negative of the oil futures spread may be viewed as an indicator of fluctuations in the price of crude oil driven by precautionary demand an empirical analysis of this indicator provides evidence of how shifts in the uncertainty about future oil supply shortfalls affect the real spot price of crude oil copyright 2010 john wiley sons ltd

the effect of uncertainty on investment evidence from texas oil drilling this paper estimates the response of investment to changes in uncertainty using data on oil drilling in texas and the expected volatility of the future price of oil using a dynamic model of firms investment problem i find that i the response of drilling activity to changes in price volatility has a magnitude consistent with the optimal response prescribed by theory ii the cost of failing to respond to volatility shocks is economically significant and iii implied volatility data derived from futures options prices yields a better fit to firms investment behavior than backward looking volatility measures such as garch jel c58 d92 g13 g31 l71 q31 the real options literature beginning with marschak 1949 and arrow 1968 and developed in bernanke 1983 pindyck 1991 and dixit and pindyck 1994 explains how firms should make decisions about investments that involve sunk costs real options theory views such investments as options in that at any point in time a firm may choose to either invest immediately or delay and observe the evolution of the investment s payoff a key insight is that the option to delay has value when future states of the world with positive returns to investing and states with negative returns are both possible even holding the expected future return constant at its present level thus in the presence of irreversibility and uncertainty a naive investment timing rule proceed with an investment if its expected benefit even slightly exceeds its cost is suboptimal because it does not account for the value of continuing to hold the option instead firms should delay irreversible investments until a significant gap develops between the investments expected benefits and costs moreover as uncertainty increases real options theory tells us that the incentive to delay should grow stronger and the gap between the expected benefit and cost necessary to trigger investment should widen while real options theory therefore prescribes how firms should carry out irreversible investments in uncertain environments it is not empirically well known

a dynamic putty semi putty model of aggregate energy demand energy conservation dominated the adjustments of the energy decade the present study develops further the aggregate analysis to revisit the question of energy flexibility within the context of a multi factor dynamic model the resulting model preserves various adding up constraints cross equation parameter restrictions and consistent indexes within an ad hoc stock adjustment dynamic process applications to data for the usa and japan confirm the estimates of large long run elasticities under the assumption of a slow adjustment process

budget deficits short term real interest rates and the specification of expected inflation an empirical investigation the purpose of this paper is to illustrate whether empirical estimates of the effects of budget deficits on short term real interest rates are sensitive to the choice of the expected inflation variable survey data on expected inflation and the rational expectations method described by mishkin 1981 are used to construct two measures of the short term real interest rate results for two previous studies on this deficit interest rate relationship are re estimated using these measures of expected inflation and the interest rate variables additional results reported in this paper further indicate that empirical estimates of the interest rate effects of budget deficits are sensitive to the choice of the expected inflation variable in addition to the choice of the inflation variable a number of other robustness tests are included we are able to conclude that 1 increases in budget deficits do not generally raise short term real interest rates and 2 short term real interest rates are not independent of

labour supply and wages among nuclear and extended households the surinamese experiment this article explores labour market behaviour of members of extended and nuclear households in suriname previous analyses have found that co operative childcare opportunities within the extended household increase female labour force participation such coordination implies correlated participation decisions which invalidates standard assumptions made in estimating participation with probits and wages with regressions we employ a gmm estimation which allows correlation among household members we find that extended and nuclear household members are not significantly different in participation propensities but do differ significantly in wages we argue that greater home production opportunities in extended households dilute labour market effort and hours reducing earnings

the effect of oil supply shocks on us economic activity what have we learned estimated responses of real oil prices and us gross domestic product gdp to oil supply disruptions vary widely we show that most variation is attributable to differences in identification assumptions and in the model specification models that allow for a large short run price elasticity of oil supply imply a larger response of oil prices and a larger longer lived contraction in us real gdp we find that if we condition on a range of supply elasticity values supported by microeconomic estimates the differences in the oil price responses diminishes we also examine the role of lag length of using pre 1973 data alternative measures of real economic activity and using the median response function instead of the modal structural model

how do oil producers respond to giant oil field discoveries abstract the classical hotelling model predicts that the optimal extraction level rises immediately after an unexpected resource discovery whereas in reality there are substantial adjustment costs in petroleum production and an average lag of several years between a discovery and the start of production using a large panel of country level production data and a difference in differences identification approach i show that domestic production levels respond before a newly found oil field comes on line and that this increase is driven by non opec producers consistent with different responses of opec and non opec drilling activity offshore fields and exceptionally large super or mega giant fields are also more likely to raise country level production given that domestic petroleum consumption rises by less in response to a discovery at least part of the increase in production seems to go into net oil exports

testing the efficiency of extraction from a stock resource the theoretical conditions for efficient extraction from a known stock resource by a competitive mining firm are reviewed these conditions are tested using proprietary data from a mining firm output price data and coefficient estimates from a translog cost system are used to compute the in situ value of the resource and the stock effect changes in the in situ value over time are then statistically compared with the expected price path the results reject the hypothesis that the data are consistent with the theoretical model and the maintained hypotheses variations of the basic model that incorporate a time varying discount rate an alternative expected price series and a constraint on the rate of output are also tested and rejected 46 references 10 tables

short term interest rates as predictors of inflation on testing the hypothesis that the real rate of interest is constant in an innovative and provocative paper in this review eugene fama presents evidence which appears to be consistent with the joint hypothesis that the real rate of interest ignoring taxes is a constant and that the market for u s treasury bills is efficient in the sense of embodying rational expectations those findings are strikingly at variance with a long list of previous studies which seemed to support the view that the real rate of interest varies over time and can be related to economic variables such as real output monetary policy and so forth 2 the methodologies which lead to these contradictory conclusions are quite different previous studies had followed the lead of irving fisher by relating nominal interest rates to distributed lags on past rates of inflation 3 these distributed lags are generally interpreted as approximations to the market s expected rate of inflation and thus any remaining variation is attributed to variation in the real rate 4 fama s methodology on the other hand draws on the fact that the difference between the market interest rate and the subsequently observed rate of inflation the ex post real interest rate consists by definition of the ex ante real interest rate plus a pure forecasting error 5 the hypothesis of market efficiency implies that these forecasting errors must be serially random thus observing ex post real rates is equivalent to observing ex ante real rates with random measurement error these errors of course confound the problem of identifying variation in the ex ante real rate in this paper we will argue that the relative magnitude of these measurement errors is such that the tests carried out by fama were not powerful enough to reject the joint hypothesis that the ex ante real rate is a constant and expectations are rational more powerful tests which are presented in this paper using the same data do lead to rejection of that hypothesis of course rejection

the shifting natural wealth of nations the role of market orientation this paper explores the effect of market orientation on known natural resource wealth using a novel dataset of world wide major hydrocarbon and mineral discoveries consistent with the predictions of a two region model the empirical estimates based on a large panel of countries show that increased market orientation causes a significant increase in discoveries of natural resources in a thought experiment whereby economies in latin america and sub saharan africa remained closed they would have only achieved one quarter of the actual increase in discoveries they have experienced since the early 1990s the results call into question the commonly held view that natural resource endowments are exogenous

the postwar stability of the fisher effect most research concerning the fisher relationship has concentrated on the magnitude and significance of the response of nominal interest rates to anticipated inflation recently attention has shifted to the stability of that response according to previous estimates the impact of anticipated inflation on interest rates varies substantially over time by extending a standard model to include tax and aggregate supply shock effects we are able to reduce such instability considerably our results also reveal that increased foreign demand for bonds lowers the interest rate

fisher phillips friedman and the measured impact of inflation on interest a reply the purpose of this paper is to demonstrate that empirical findings which persistently appear to contradict the fisher hypothesis that the nominal rate of interest should rise by the full amount of an increase in anticipated inflation are due basically to a failure to control for changes in the real rate of interest that are associated with changes in anticipated inflation we are guided in our search for proper specification of a fisher equation by a simple general equilibrium model which is employed to derive the impact of a change in anticipated inflation upon nominal interest given the requirement that commodity money and labor markets remain in equilibrium in effect we depart from the empirical tradition which has grown up around testing of the fisher hypothesis that takes the real interest rate to be independent of anticipated inflation and argues that for anticipated inflation properly measured the data ought to support the fisher hypothesis 1

learning by drilling interfirm learning and relationship persistence in the texas oilpatch author s kellogg ryan m abstract production in many industries such as construction and heavy manufacturing relies on inputs from both lead firms and contractors these firms joint productivity often hinges on their ability to share information and coordinate activities suggesting that they have strong incentives to learn about each other s personnel procedures and expertise this learning differs from standard learning by doing in that it is relationship specific its benefits are not appropriable outside the relationship in which the learning takes place in this paper i empirically examine the importance of relationship specific learning using high frequency data from oil and gas drilling i find that the joint productivity of a lead firm and its drilling contractor is enhanced significantly as they accumulate experience working together this result is robust to other relationship specificities i also find that firms appear to recognize the benefits of joint experience controlling for other specificities lead firms are more likely to work with contractors with which they have substantial prior experience than those with which they have worked relatively little

on optimal extraction under asymmetric information over reclamation costs abstract polluting exhaustible resource extraction ends with costly reclamation and producers have better information about future reclamation costs than the regulator this paper analyzes optimal contract between the regulator and the mining firm in a two stage model in which extraction and pollution generation is followed by reclamation with asymmetric information over reclamation costs the contract consists of a pollution tax and a mechanism used for cost information revelation and it extracts all the profit from the highest cost type leaves profits for the more efficient types and dictates a reclamation effort that is lower than the complete information effort it is further shown that the optimal pollution tax under asymmetric information can be lower or higher than the tax under complete information in addition the exclusion of the most expensive types is analyzed the results can help to design policies that improve the existing ones by saving public funds by improving the state of the environment and by excluding those mining operations that do not produce net benefits for the society

the long run relationship between interest rates and inflation some cross country evidence abstract this paper analyzes the effect of anticipated inflation on nominal interest rates paying special attention to the stability of this relationship over various regimes these regimes are analyzed to find out whether the inflation forecastability proposition recently advanced by barsky explains the observed poor performance of the fisher equation with historical data the analyses make use of the so called threshold and digression models and data from 11 western countries for 1875 1984 the main result of this paper is that the forecastability proposition does not explain the weakness of the anticipated inflation effect on interest rates rather various institutional factors seem to be of more importance

drilling and debt this paper documents a previously unrecognized debt related investment distortion using detailed project level data for 69 firms in the oil and gas industry we find that highly levered firms pull forward investment completing projects early at the expense of long run project returns and project value this behavior is particularly pronounced prior to debt renegotiations we test several channels that could explain this behavior and find evidence consistent with equity holders sacrificing long run project returns to enhance collateral values and by extension mitigate lending frictions at debt renegotiations

using shadow wages to estimate labor supply of agricultural households with few exceptions most studies of the labor demand and supply decisions of agricultural households in developing countries have relied on the empirical advantages of separability given the questionable nature of some of the assumptions sufficient for separability i apply a recent methodology that accounts for the simultaneity between the production and consumption decisions of a farm household using data from rural india direct estimates of the marginal productivities shadow wages of family male and female labor are derived from a cobb douglas agricultural production function the estimated shadow wages and income are then used as regressors in a structural model of labor supply

explanations for the 2014 oil price decline supply or demand abstract the brent price of crude oil declined from 112 in june 2014 to a low of 31 in january 2016 both nominal prices a cumulative decrease of more than 70 some attribute the decline to increased oil production due to the u s shale revolution this paper proposes a variety of diagnostics to assess the how consistent this explanation is with the data i find that the data are broadly inconsistent with this attribution of the decline to shale oil rather the data are more consistent with a demand side explanation of weakening global economic conditions and demand for commodities including but not limited to oil in summary there is no evidence that the u s shale revolution played a significant role in the decline in oil prices since 2014 rather the evidence suggests that weakening oil demand played a much stronger role in driving the 2014 decline in oil prices

market wages family composition and the time allocation of children in agricultural households this article draws upon a time allocation survey of a four year panel of households from six villages in semi arid tropic rural india the inter relationships among adult male female and child market wage rates and time allocated to domestic activities leisure and schooling by boys and girls are analysed the results based on the pooled time series and cross section individual observations suggest that adult and child wage rates play an important role in the time allocation of both boys and girls

opec behavior a test of alternative hypotheses since interpretations of past and future oil price patterns depends on the model chosen the author tests and compares alternative theories of opec as a first step in validating the choice on any one model the results show that among opec countries the partial market sharing cartel model is the only model not rejected by at least some of the 11 members and gives the best explanation of production in comparison with 11 non opec countries the competitive model could not be rejected for 10 of the 11 non opec producers this raises the question of why if opec is a cartel friedman s predictions have not come true and introduces new questions for future research 19 references 3 tables

cleaning house new perspectives on households and economic development abstract this paper provides a critical review of the recent literature on households and economic development three related points are developed 1 household activities can be analyzed in economic terms particularly if these terms are broadly defined to encompass such factors as risk and uncertainty 2 significant differences between the economic position of men women and children within the patriarchal household mean that it cannot be treated as an undifferentiated unit of analysis 3 microeconomic analysis of the household must be situated within a larger structural analysis of gender and age based inequalities and their interaction with class structure and national position within the world capitalist system

price dynamics under imperfect information abstract the paper considers the pricing decision of a monopolist firm having demand and costs exposed to nominal and real shocks which include both permanent and transitory changes the firm obtains information through both price and quantity signals and the price equation is found by use of a filtering technique it is shown that imperfect information implies nominal price smoothing where the price adjusts only partially relative to the past price by incorporating new information observed through price and quantity signals

fisher s paradox and the theory of interest irving fisher s theory of interest has proved to be a most durable and influential contribution to economic theory a central element of fisher s contribution is the fisher hypothesis that over the longer term the real rate of interest is approximately constant being determined largely by time preference with movements in the nominal interest rate reflecting movements in the rate of inflation one for one the paradox of the fisher hypothesis is that despite its wide acceptance as the cornerstone of interest rate theory most empirical evidence appears to be inconsistent with the hypothesis at least in its strictest form this empirical anomaly was noted by fisher himself who attributed it to money illusion in the fifty years following the publication of the theory of interest a considerable literature has evolved around this paradox the unifying theme of this literature is a common acceptance of the essence of fisher s hypothesis most of the energy in this literature has been devoted to explaining systematic movements in the real rate of interest and to providing reasons why the relationship between the nominal interest rate and inflation may only be approximate in

oil production responses to price changes an empirical application of the competitive model to opec and non opec countries abstract falling oil prices over the last decade accompanied by over production by some opec members and the growth of non opec supply warrant further empirical investigation of the competitive model to ascertain production behavior a supply function based on a modification of griffin s model is estimated using data from 1973 1997 the sample period unlike griffin s however includes phases of price increase 1970s and price decrease 1980s 1990s thus providing a better framework for examining production behavior using the competitive model the opec results do not support the competitive hypothesis instead a negative and significant price elasticity of supply is obtained this result offers partial support for the target revenue theory for most of the non opec members the estimates support the competitive model opec s loss of market share and the drop in the share of oil based energy should signal adjustments in price and quantity based on a competitive world market for crude oil

carbon curse in developed countries among the ten countries with the highest carbon intensity six are natural resource rich countries this suggests the existence of a carbon curse resource rich countries would tend to follow more carbon intensive development paths than resource poor countries we investigate this assumption empirically using a panel data method covering 29 countries oecd and bric and seven sectors over the 1995 2009 period first at the macroeconomic level we find that the relationship between national co 2 emissions per unit of gdp and abundance in natural resources is u shaped the carbon curse appears only after the turning point second we measure the impact of resource abundance on sectoral emissions for two groups of countries based on their resource endowments we show that a country rich in natural resources pollutes relatively more in resource related sectors as well as all other sectors our results suggest that the debate on climate change mitigation should rather focus on a comparison of resource rich countries versus resource poor countries than the developed country versus developing country debate

refining the workhorse oil market model the kilian and murphy journal of applied econometrics 2014 29 454 478 structural vector autoregressive model has become the workhorse model for the analysis of oil markets i explore various refinements and extensions of this model including the effects of 1 correcting an error in the measure of global real economic activity 2 explicitly incorporating narrative sign restrictions into the estimation 3 relaxing the upper bound on the impact price elasticity of oil supply 4 evaluating the implied posterior distribution of the structural models and 5 extending the sample i demonstrate that the substantive conclusions of kilian and murphy 2014 are largely unaffected by these changes

why real interest rates were so low in the 1970 s the economic turmoil of the 1970 s resulted in record postwar increases in inflation unemployment and nominal interest rates yet it was declines that were hardest to explain the average real value of a share of common stock plummeted productivity growth evaporated real interest rates measured as the spread between nominal interest rates and the inflation rate turned negative see table 1 over the past decade an explosion has occurred in the amount of attention paid to the relationship between nominal and thus real interest rates and expected inflation rates a good deal of this effort has been directed toward empirical analysis of the fisher neutrality hypothesis that nominal rates respond one for one with expected inflation rates most empirical tests of the fisher hypothesis have been bivariate interest rates were regressed on a constant and on actual or expected inflation measures estimates of the impact of inflation on interest rates in these and even in extended models are often significantly below one are often statistically imprecise and tend to be unstable over time the middle column of table i reflects this the coefficient of inflation on nominal interest rates there drops from 0 78 to 0 59 in the latter 1970 s another branch of work on nominal interest rates has concentrated on the institutional impediments to the fisher hypothesis robert mundell and james tobin demonstrate that nominal rates change by a smaller amount than the expected inflation rate does when a real balance effect exists and money pays no interest michael darby and martin feldstein on the other hand argue that nominal rates should exhibit a greater thanunity response to expected inflation due to the nature of u s income tax laws 2 here i estimate the relation between interest rates expected inflation and real forces such estimates are required for evaluating the effects of inflation on saving investment the distribution of income and the redistribution of wealth to generate estimates of the net impact of these various factors on interest rates and to avoid the identification and simultaneity problems masked but not often remedied by instrumental variables techniques i employ only exogenous regressors to buttress the argument i examine the individual links in the chain which are summarized in the reduced form the novel aspect of the model presented in section i is its addition of aggregate supply shocks to the determination of interest rates i trace the reduction in the supply of complementary factor inputs in the 1970 s to a decline in the demand for capital and therefore in real interest rates the inclusion of this supply force along with expected inflation allows one to distinguish between two offsetting effects on interest rates the depressing effect on real rates through lower investment demand and the elevating effect on nominal rates of higher expected inflation the results in section ii not only strongly support the economic and statistical importance of supply shocks on real interest rates but also resolve some longstanding interest rate puzzles allowing for the impact of factor supply produces a significant estimated response to expected inflation for a sample that ends prior to late 1960 s the magnitude assistant professor school of business administration university of california berkeley i would like to thank george akerlof robert j gordon robert a meyer joe peek janet yellen the members of the economic analysis and policy seminar at berkeley participants at the nber conference on inflation and financial markets and anonymous referees for helpful comments data resources supplied data and computational services financial support was provided by the berkeley program in finance and nsf grant ses8109093 linda pacheco supplied able research assistance errors of omission or commission are my responsibility see william gibson david pyle john carlson and thomas cargill and robert meyer 2maurice levi and john makin derive the reducedform effect of expected inflation on nominal interest rates as a function of the structural parameters

estimating the long run relationship between interest rates and inflation a response to mccallum abstract this note demonstrates that bennett mccallum s recent critique of low frequency estimates of macroeconomic relationships is of little empirical significance it also demonstrates that readily available and frequently used techniques can be used to diagnose the problem mccallum raises finally it shows that the standard critique of expectational distributed lags is not warranted once the role of learning by economic agents is recognized

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

more flexible use of survey data on expectations in macroeconomic models a flexible procedure is proposed whereby both the random and systematic errors in measurement of survey data on inflation expectations can be appropriately handled when these surveys are used in the estimation of macroeconomic models during the period 1952 1980 livingston s two expectations series and the src series systematically underestimated inflation expectations by nearly 25 the asa nber survey however does not exhibit such underestimation thus the use of the livingston or src data as an unbiased measure of the true expectations of inflation would result in overestimation of the fisher effect and the ex ante real interest rate

mineral depletion with cost as the extraction limit a model applied to the behavior of prices in the nickel industry abstract this article follows papers by pindyck and heal and barrow in applying a hotelling type depletion model to a particular resource industry in this case that of nickel by means of the model the resource rent per ton of nickel is calculated as the proper index of extractive resource scarcity the time path of this resource rent indicates that the model explains industry behavior well and that as in the two previous studies depletion has been an important determinant of prices and rents in this industry

government borrowing and tax adjusted real and nominal interest rates the purpose of this paper is to test for the effect of federal government budget deficits on one year tax adjusted nominal and real interest rates in an is lm as model the results suggest that the specification of the dependent variable is a crucial issue in the debate over the linkage between deficits and interest rates the evidence shows a positive and significant effect of various measures of the federal government deficit and debt on the real tax adjusted treasury bill rate in both the levels and the first differenced equations but not on the nominal tax adjusted rate the positive and significant deficit debt coefficients are also confirmed when the first differenced equation is estimated by instrumental variables and when the equation is estimated over various time periods thus there is robust evidence of a positive linkage between federal government borrowing and the tax adjusted real but not nominal interest rates

productivity of men and women and the sexual division of labor in peasant agriculture of the peruvian sierra abstract this paper estimates the productivity of men and women in the peasant agriculture of the peruvian sierra using recent household survey data a sexual division of labor on the farm implies that male and female labor are not perfectly substitutable evidence is found for female specialization on livestock production a translog production function reveals that the use of animal traction and land affect the marginal productivity of male and female labor differently suggesting that the two types of labor cannot be aggregated overall adult male labor is found to contribute more to farm output at the margin than adult female labor though the extent of the difference is sensitive to how farm output and the labor inputs are measured

the trade off between child labour and human capital formation a tanzanian case study we investigate the degree to which there is a trade off between child labour and human capital formation using time log data of children from a tanzanian household survey we find that a tradeoff between hours of work and study exists and hours of work tend to be more affected by social conditions than hours of study hours of work are negatively correlated to reading and mathematical skills through the reduction of human capital investment activities indicating a trade off between child labour and human capital the results point up the complexity of the issue and the need for detailed time allocation data

determinants of women s time allocation in rural bangladesh time allocation patterns of women in developing countries have received attention due to interest in 2 problems the 1st is whether womens time is governed by economic constraints or by local customs and patriarchy 2nd is the question of whether these women have a 2 way to work or not to work or a 3 way to work inside or outside the family or not to work choice structure an economic framework is outlined that elucidates how jointly made decisions on labor force participation and hours of work affect womens time allocation decisions this econometric model of womens time allocation is based on a random sample of 500 households in different regions of rural bangladesh market production is defined as work for cash income whether inside or outside the home the study focused on married women aged 15 49 of whom 195 out of 444 engaged in market production these women tended to be younger live closer to market centers and have more schooling than those not participating in market production time use by these women was influenced by individual and household economic factors and was not rigidly set by local customs thus women in rural bangladesh will probably respond to market opportunities as development proceeds there the husbands educational level also had a large effect on time allocation and this may have been due to a spouse selection bias rather than the husband determining his wifes time use

the value and allocation of time in rural botswana abstract time use data indicate that there is substantial surplus labor in rural areas of botswana with the incidence of underutilization varying by age sex and asset position time allocations are influenced by economic incentives i e income and productivity effects the more productive capital the household has the more productive work its members perform particularly its children the positive productivity effect of capital on economic work somewhat outweighs its negative income effect time allocations also are constrained by a culturally determined division of labor by age and sex which however shows some flexibility at the margin

the hotelling rule in non renewable resource economics a reassessment harold hotelling s 1931 contribution is known for providing a basic principle the hotelling rule to the economics of non renewable resources nearly ninety years later empirical tests conclude the rule lacks empirical validity requiring strong amendments to describe the long term aggregate behavior of its target object on the basis of hotelling s unpublished archival material this paper revisits the place given to the hotelling rule in non renewable resource economics our reconstruction shows that hotelling s 1931 paper has been misinterpreted from the outset the hotelling rule was not valid for mineral resources in contrast the consideration of two inherent geological constraints alongside exhaustibility offered the opportunity for an alternative basic framework capable to generate bell shaped and u shaped equilibrium trajectories for supplies and prices respectively inspired by this unknown aspect of hotelling s work brought to light by our archival investigation we sketch this alternative basic model enabling non renewable resource economics to circumvent the empirical shortfalls of the hotelling rule

drilling like there s no tomorrow bankruptcy insurance and environmental risk this paper measures the effects of bankruptcy protection on industry structure and environmental outcomes in oil and gas extraction using administrative data from texas i exploit variation in an insurance requirement that reduced firms ability to avoid liability through bankruptcy among small firms the policy substantially improved environmental outcomes and reduced production most production was reallocated to larger firms with better environmental records but high cost production where social cost may have exceeded social benefit decreased these results suggest that incomplete internalization of environmental costs due to bankruptcy is an important determinant of industry structure and safety effort in hazardous industries

a test of the hotelling valuation principle time series tests of the hotelling r percent rule for natural resource prices have not been strongly supportive but the tests and the data are subject to serious difficulties we propose here an alternative testing strategy based on another but less widely known implication of the hotelling model we test this implication which we call the hotelling valuation principle by regressing the market values of the reserves of a sample of u s domestic oiland gas producing companies on their estimated hotelling values we find that the estimated hotelling values account for a significant portion of the observed variations in market values and that the hotelling measures are better indicators of the market values of petroleum properties than two widely cited publicly available alternative appraisals

hotelling under pressure we show that oil production from existing wells in texas does not respond to oil prices while drilling activity and costs respond strongly to explain these facts we reformulate hotelling s class

the intrahousehold demand for nutrients in rural south india individual estimates fixed effects and permanent income good estimates of nutrient intake responses to prices and income are very useful for the evaluation of the numerous efforts to improve nutrition in many developing countries through pricesubsidy and income generation policies we discuss three problems in standard estimates of these responses and then illustrate their implications for nutrient demand relations for a poor sample from rural south india 1 intra household nutrient allocations usually are ignored in this case nutrient intakes for females systematically have algebraically lower price elasticities than do those for males which may leave the females particularly vulnerable at times of food shortages 2 unobserved fixed effects may bias the estimates of responses to observed variables in this case not only the community fixed effects on which the previous literature has focused but also household and individual fixed effects are important failure to control for them results in substantial algebraically upward biases in many estimated price responses 3 most previous studies use current instead of permanent income which a priori may account for the low estimated income elasticities in this case however the use of permanent income does not change the conclusion that the nutrient intakes responses to income are quite small

oil at risk political violence and accelerated carbon extraction in the middle east and north africa abstract what effect does the threat of expropriation have on resource extraction much of the economic literature suggests that uncertainty reduces investment but the theory of risk induced extraction suggests the opposite in this paper we test this theory in the context of political violence which poses a real threat of state destabilization and violent expropriation of property rights facing this uncertainty we find that oil producers in the middle east and north africa increase oil production in response to political violence this finding has important negative consequences for the world in terms of climate change and demonstrates a previously untested mechanism through which exhaustible resource supply is flooding the market

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

exploration activity long run decisions and the risk premium in energy futures investment by oil firms positively affects the futures basis and negatively predicts excess returns on crude oil futures i build an equilibrium model of drilling exploration and storage to understand these facts firms capital stock lowers extraction costs as firms drill in increasingly expensive fields drilled wells produce the resource at a geometrically declining rate however by specifying consumers habit level equaling production from old wells the futures basis and risk premium are only related to drilling investment and inventory investment leads to a more elastic drilling response by firms and dampens oil price increases from demand shocks thus lowering the risk premium received october 10 2015 editorial decision march 30 2018 by editor philip strahan author has furnished an internet appendix which is available on the oxford university press web site next to the link to the final published paper online

labor market opportunities and intrafamily time allocation in rural households in south asia this paper utilizes a time allocation survey of a four year panel of households from six villages in semi arid tropic rural india estimates of the inter relationships between adult male female and child market wage rates and time allocated to the market domestic production leisure and schooling by boys and girls are presented the role of individual unobservable heterogeneity and self selection into activity participation is also accounted for the overall results suggest the importance of the opportunity cost of time in intrafamily time use

evidence of the fisher effect from u k indexed bonds newly available data from the u k market for indexed securities are used to test the fisher hypothesis for monthly observations of interest rates at 14 maturities the hypothesis that the after tax nominal interest rate is a constant plus anticipated inflation proves to be a reasonable approximation of reality for longer maturities the coefficients on the expected rate of inflation are approximately equal to one the mundell tobin effect is in evidence for shorter maturities the inverted fisher effect is in evidence for shorter maturities the inverted fisher effect is decisively rejected the evidence suggests that past difficulties encountered in trying to prove the fisher effect have been due to the lack of a direct measure of inflation expectations and real interest rates copyright 1992 by mit press

on measuring natural resource scarcity conclusions concerning trends in natural resource scarcity may depend critically on the choice of scarcity index unfortunately the prevalence of vertical integration in natural resource industries has hindered the use of some otherwise desirable scarcity measures in this paper duality theory is used to derive an econometric procedure for estimating one such measure the shadow price of the resource in situ empirical results for the canadian metal mining industry indicate that resource scarcity as measured by this shadow price has decreased substantially over time
