a semiparametric approach to short term oil price forecasting abstract in this paper it is shown how the garch properties of oil price changes can be employed to forecast the oil price distribution over short term horizons the forecasting methodology is semiparametric and it is based on the bootstrap approach the results of an out of sample forecasting exercise carried out using the brent oil price series suggest that the forecasting approach can be used to obtain a performance measure for the forward price in addition to compute interval forecasts for the oil price

informational content of government hogs and pigs reports we examine the value of the informational content of quarterly government reports which estimate forthcoming supplies of hogs and pigs it is assumed that a hypothetical futures trader obtains the government reports one day in advance of their release a futures market trading rule is established which uses early access to the reports together with a priori expectations of the reports contents we find the market information in the government reports is of little or no value to a futures trader in advance of the release date because this information is already incorporated in the futures price

forecasting the real price of oil time variation and forecast combination abstract this paper sheds light on the questions whether it is possible to generate an accurate forecast of the real price of oil and how it can be improved using forecast combinations for this reason the following paper will investigate the out of sample performance of seven individual forecasting models the results show that it is possible to construct better forecasts compared to a no change benchmark for horizons up to 24 months with gains in the mspe ratio as high as 25 in addition some of the existing models will be extended e g the u s inventories model by introducing more suitable real time measures for the brent crude oil price and the var model of the global oil market by using different measures for the economic activity furthermore the time performance investigated by constructing recursively estimated mspe ratios discovers potential weaknesses of the used models hence several different combination approaches are tested with the goal of demonstrating that a combination of individual models is beneficial for the forecasting performance thereby a combination consisting of four models has proven to have a lower mspe ratio than the best individual models over the medium run and in addition to be remarkably stable over time

a comparison of petroleum futures versus spot prices as predictors of prices in the future abstract even though studies have indicated that the futures market leads the spot market in price discovery this paper hypothesizes that the predictive significance of each should be the same a number of different statistical tests are presented to test this hypothesis when deseasonalized data is employed the predictive significance of each series is found to be the same but when actual prices are employed futures prices did correctly anticipate the observed seasonal pattern

evaluating natural resource investments notwithstanding impressive advances in the theory of finance over the past 2 decades practical procedures for capital budgeting have evolved only slowly the standard technique which has remained unchanged in essentials since it was originally proposed see dean 1951 bierman and smidt 1960 derives from a simple adaptation of the fisher 1907 model of valuation under certainty under this technique expected cash flows from an investment project are discounted at a rate deemed appropriate to their risk and the resulting present value is compared with the cost of the project this standard textbook technique reflects modern theoretical developments only insofar as estimates of the discount rate may be obtained from crude application of single period asset pricing theory but see brennan 1973 bogue and roll 1974 turnbull 1977 constantinides 1978 the inadequacy of this approach to capital budgeting is widely acknowledged although not widely discussed its obvious deficiency is its the evaluation of mining and other natural resource projects is made particularly difficult by the high degree of uncertainty attaching to output prices it is shown that the techniques of continuous time arbitrage and stochastic control theory may be used not only to value such projects but also to determine the optimal policies for developing managing and abandoning them the approach may be adapted to a wide variety of contexts outside the natural resource sector where uncertainty about future project revenues is a paramount concern

is there agreement between beneficiaries on who should bear the costs of conserving farm landscapes abstract in recent years market based incentives have been regarded as a potential solution for addressing market failure related to environmental externalities determining the optimal payment schedule to facilitate such market mechanism typically involves a valuation exercise to capture the static benefits received by beneficiary groups from the public good in this study we augment the valuation estimates with a notion of fair share by assessing opinions of two beneficiary groups tourists and bed and breakfast owners regarding an acceptable division of the burden of financing the public good we find a significant difference in views tourists believe that their accommodation providers should contribute almost twice the amount that they themselves are willing to pay on the contrary a majority of bed and breakfast owners surveyed were against burdening tourists with any additional payments

accuracy and efficiency in the u s department of energy s short term supply forecasts one step ahead forecasts of quarterly crude oil natural gas electricity and coal supplies are evaluated under two general approaches accuracy based measures and classification or directional based measures results suggest the u s department of energy doe supply forecasts for u s domestic energy products are generally more accurate than a naive alternative there is only limited evidence of bias and inefficiency in the forecasts although there is some evidence of error repetition directional forecasts for supply changes are statistically better than random but they generally do not outperform a naive forecast

financial statement comparability and expected crash risk this study examines the impact of financial statement comparability on ex ante crash risk using the comparability measures of de franco et al 2011 we find that expected crash risk decreases with financial statement comparability and this negative relation is more pronounced in an environment where managers are more prone to withhold bad news we also provide evidence that comparability can mitigate the asymmetric market reaction to bad versus good news disclosures our results suggest that financial statement comparability disinclines managers from bad news hoarding which reduces investors perceptions of a firm s future crash risk

can we improve the perceived quality of economic forecasts a number of topics are discussed concerning how economic forecasts can be improved in quality or at least in presentation these include the following using 50 uncertainty intervals rather than 95 noting that even though forecasters use many different techniques they are all occasionally incorrect in the same direction that there is a tendency to underestimate changes that some expectations and recently available data are used insufficiently lagged forecasts errors can help compensate for structural breaks series that are more forecastable could be emphasized and that present methods of evaluating forecasts do not capture the useful properties of some methods compared to alternatives

the rationality and price effects of u s department of agriculture forecasts of oranges this article examines the effect of public information on the orange juice market we investigate the rationality information content and price effects of u s department of agriculture forecasts of the production of oranges u s department of agriculture forecasts are found to be unbiased and efficient the first forecast contains the most new information and subsequent reports become valuable only when freezes occur significant price movements occur in response to announced production in both florida and california however the majority of price variations cannot be explained by these movements in supply

social norms of work ethic and incentives in organizations abstract in this paper i model the relation between the dissemination of social norms of work effort work ethic in a given society and the choice of incentives by firms and i motivate it by presenting evidence from three different datasets that suggests that work ethic is correlated with the intensity of firms incentives when the effort choices of different agents in a firm are complementary having hard working coworkers makes an agent more productive therefore in equilibrium she will work harder foreseeing that a work ethic is more useful to hard working agents parents will be more willing to transmit it in societies in which the probability that their offspring will have coworkers with strong work ethic is higher i then expand the model to incorporate the firm technology choice allowing firms to decide between complementary and separable production processes in societies with wide dissemination of work ethic firms will want effort to be complementary as in modern production processes while the opposite is true when the dissemination of work ethic is narrow finally i investigate the comparative dynamics of the model

optimal contracting with endogenous social norms research in sociology and ethics suggests that individuals adhere to social norms of behavior established by their peers within an agency framework we model endogenous social norms by assuming that each agent s cost of implementing an action depends on the social norm for that action defined to be the average level of that action chosen by the agent s peer group we show how endogenous social norms alter the effectiveness of monetary incentives determine whether it is optimal to group agents in a single or two separate organizations and may give rise to a costly adverse selection problem when agents sensitivities to social norms are unobservable

testing the rationality of doe s energy price forecasts under asymmetric loss preferences this paper examines the rationality of the price forecasts for energy commodities of the united states department of energy s doe departing from the common assumption in the literature that doe s forecasts are based on a symmetric underlying loss function with respect to positive vs negative forecast errors instead we opt for the methodology of elliott et al 2005 that allows testing the joint hypothesis of an asymmetric loss function and rationality and reveals the underlying preferences of the forecaster results indicate the existence of asymmetries in the shape of the loss function for most energy categories with preferences leaning towards optimism moreover we also examine whether there is a structural break in those preferences over the examined period 1997 2012

empirical research on accounting choice abstract we review research from the 1990s that examines the determinants and consequences of accounting choice structuring our analysis around the three types of market imperfections that influence managers choices agency costs information asymmetries and externalities affecting non contracting parties we conclude that research in the 1990s made limited progress in expanding our understanding of accounting choice because of limitations in research design and a focus on replication rather than extension of current knowledge we discuss opportunities for future research recommending the exploration of the economic implications of accounting choice by addressing the three different reasons why accounting matters

interdependent behavior and the effect of taxes abstract the paper studies the effect of taxes on labor supply in a model with interdependent behavior i e individuals preferences depend on other people s behavior it is found that not taking the interdependency into account can lead to a serious bias in the predicted effects of a tax change it is also shown that interdependent behavior can give rise to spikes in the hours distribution such spikes often have been attributed to quantity constraints

the provision of incentives in firms i ncentives are the essence of economics despite many wide ranging claims about their supposed importance there has been little empirical assessment of incentive provision for workers the purpose of this paper is to critically overview existing work on the provision of incentives since the interests of workers and their employers are not always aligned a large theoretical literature has emphasized how firms design compensation contracts to induce employees to operate in the firm s interest this literature has reached into many areas of compensation and has pointed to a multitude of different mechanisms that can be used to induce workers to act in the interests of their employers these include piece rates options discretionary bonuses promotions profit sharing efficiency wages deferred compensation and so on my objective here is to evaluate this literature in the light of a growing empirical literature on compensation where possible i will address the literature from two perspectives first an underlying assumption of this literature is that individuals respond to contracts that reward performance accordingly i consider whether agents behave in this way and whether these responses are always in the firm s interest second i address whether firms write contracts with these responses in mind in other words do contracts look like the predictions of the theory incentives are provided to workers

are there gains from pooling real time oil price forecasts the answer as to whether there are gains from pooling real time oil price forecasts depends on the objective the approach of combining five of the leading forecasting models with equal weights dominates the strategy of selecting one model and using it for all horizons up to two years

the value of public information in commodity futures markets abstract the informational value of u s department of agriculture usda corn and soybean production forecasts is investigated for the period 1971 1992 three tests of informational content are applied overall the results suggest usda corn and soybean forecasts provide valuable information to participants in commodity futures markets this value does appear to have declined especially since the mid 1980s

are harvest forecasts news usda announcements and futures market reactions futures market price data for maize and soyabeans are used to examine reactions to us department of agriculture harvest forecasts these forecasts are widely known and reasonably accurate so failure to find significant reaction would indicate that the usda did not contribute additional news relative to information already possessed by traders various t tests f tests and nonparametric chi square tests indicate rejection of the null hypothesis of no significant difference between means of absolute values or variances of changes in closing prices on days following a usda announcement and other days thus the data indicate that significant information is contained in the forecasts

speculative price economic welfare and the idiot of chance p aul cootner stimulated significant research on the subject of speculative markets in both commodities and equities his papers 1960 1964 1967 were original and provocative one paper began with the statement the subject matter of this paper is bound to be considered heresy i can say that without equivocation because whatever views anyone expresses on this subject are sure to conflict with someone else s deeply held beliefs 1964 p 231 most of the papers concerned with the operation of futures markets in commodities test the efficiency of the market by examining the stochastic nature of futures prices which samuelson refers to as the idiot of chance in particular it is asked whether the price of a futures contract is a martingale cootner s contention which runs counter to the tide of academic writings is that speculative prices are not random walks but are constrained by economically determined barriers 1964 ch 11 the present paper is in the spirit of cootner s thinking about the economic and welfare implications of speculative markets my main conclusions are as follows 1 the optimality of resource allocation defined as the sum of consumer and producer surplus depends upon the accuracy of the forward price at the time production decisions are made as a forecast of the subsequent spot price when consumption occurs the existence or nonexistence of the martingale property of futures prices between these two dates is irrelevant for welfare purposes 2 social loss is a multiple of the square of the forecast error between the forward price and the subsequent spot price expected social loss is irreducible when the forward price is equal to the mathematical expectation of the subsequent spot price 3 the longer the period between the production decisions and the subsequent consumption decisions the greater the bias between the forward price and subsequent spot price 4 it has been claimed that in an efficient market the spot price at time t should just depend upon the price at t 1 and not upon earlier prices it is proved that this situation is neither a necessary nor a sufficient condition for rational expectations 5 therefore there is a tenuous connection between the stochastic nature of speculative price and measures of economic welfare but there is a direct connection between the forecast errors and economic welfare

can contracts signal social norms experimental evidence we investigate whether incentive schemes signal social norms and thus affect behavior beyond their direct economic consequences a one shot principal agent experiment is studied where prior to contract choice principals are informed about the past actions of other agents and thus have more information about norms of behavior compared with a setting in which principals are uninformed agents exert substantially higher effort under a fixed wage contract when they are aware that an informed principal chose this contract the informed principal s choice apparently signals a norm not to exploit trust which leads to more trustworthy behavior this mechanism s robustness is explored in further experiments data as supplemental material are available at http dx doi org 10 1287 mnsc 2015 2336 this paper was accepted by uri gneezy behavioral economics

politicians payments in a proportional party system abstract are there monetary returns to politics this question is approached in this paper as one of few to quantify the monetary returns to holding political office in a country with proportional representation system i apply a difference in difference setting with a carefully chosen control group to rich data on candidates to the swedish national parliament both short and long run effects of being elected on different types of income are estimated results show that yes mostly thanks to relatively high remuneration while still in office politics can yield positive monetary returns in the long run however the effect is instead compositional in the sense that ex politicians receive more pension income and work less

evaluating information in multiple horizon forecasts the doe s energy price forecasts abstract the united states department of energy s doe quarterly price forecasts for energy commodities are examined to determine the incremental information provided at the one through four quarter forecast horizons a direct test for determining information content at alternative forecast horizons developed by vuchelen and gutierrez vuchelen j and gutierrez m i a direct test of the information content of the oecd growth forecasts international journal of forecasting 21 2005 103 117 is used the results suggest that the doe s price forecasts for crude oil gasoline and diesel fuel do indeed provide incremental information out to three quarters ahead while natural gas and electricity forecasts are informative out to the four quarter horizon in contrast the doe s coal price forecasts at two three and four quarters ahead provide no incremental information beyond that provided for the one quarter horizon recommendations of how to use these results for making forecast adjustments is also provided

social norms and economic incentives in firms abstract this paper studies the interplay between economic incentives and social norms in firms we introduce a general framework to model social norms arguing that norms stem from agents desire for or peer pressure towards social efficiency in a simple model of team production we examine the interplay of three types of contracts with social norms we show that one and the same norm can be output increasing neutral or output decreasing depending on the contract multiplicity of equilibria and crowding out effects of steeper incentives can arise

fiscal year ends and nonlinear incentive contracts the effect on business seasonality salesperson and executive compensation contracts typically specify a nonlinear relationship between firm revenues and pay these agents therefore have incentive to manipulate prices influence the timing of customer purchases and vary effort over their firms fiscal years this paper empirically establishes results consistent with agents focusing on performance over the fiscal year most notably in addition to varying with the calendar business cycle manufacturing firms sales are higher at the end of the fiscal year and lower at the beginning than they are in the middle further evidence is found in fiscal year price movements and patterns in the industry variation of fiscal year effects

social norms and gift behavior theory and evidence from romania in many developing and transitional countries with limited public income redistribution inter household transfers in general and gifts in particular are sizable and very important we use unique romanian survey data that enables us to isolate pure gifts from other private transfers we explicitly focus on the importance of community wide social norms and find that they indeed play a major role for both the occurrence and the values of gifts more exactly our results suggest that the overall predominant gift motive among romanian households is a norm of reciprocity moreover this norm seems to be dominating for gifts to middle and high income households even though poor households receive to the same extent norms of both impure altruism and reciprocity tend to be important hence although the poor may not reciprocate gifts to the same extent as the rich they still receive since there is a social norm to give especially to the poor

what do economists know an empirical study of experts expectations for more than three decades economic columnist joseph a livingston has canvassed a panel of economists twice a year eliciting their six month and twelve month forecasts for more than a dozen key variables this study analyzes whether the experts predictions are unbiased and whether complete use was made of all relevant known information unbiasedness and completeness being necessary conditions for fully rational expectations little bias was found in either the half year or full year predictions but extensive underutilization of information particularly data on monetary growth occurred to prophecy is extremely difficult especially with respect to the future chinese proverb do economists expectations regarding key price and nonprice variables utilize all known relevant information in an unbiased efficient manner this is a worthy subject for research for several reasons properties of experts predictions likely form an upper bound for those of laymen further as john muth 14 has noted the character of dynamic processes is typically very sensitive to the way expectations are influenced by the actual course of events p 316 hence we need to know precisely how events do affect expectations finally the common practice of replacing a variable s generally unobserved expectation with a proxy based on its past values will be unbiased and will not cause bias in other

tests for multiple forecast encompassing in the evaluation of economic forecasts it is frequently the case that comparisons are made between a number of competing predictors a natural question to ask in such contexts is whether one forecast encompasses its competitors in the sense that they contain no useful information not present in the superior forecast we develop tests for this notion of multiple forecast encompassing which are robust to properties expected in the forecast errors and apply the tests to forecasts of uk growth and inflation copyright 2000 john wiley sons ltd

how control system design influences performance misreporting this paper investigates reporting honesty when managers have monetary incentives to overstate their performance we argue that managers who report about their performance will take into account how their report affects their peers i e other managers at the same hierarchical level this effect depends on the design of the organization s control system in particular on the reward structure and the information policy regarding individual performance reports the reward structure determines if peers monetary payoff is increased or decreased when managers claim a higher level of performance the information policy determines if managers will be able to link individual peers to their reports and affects the nonmonetary costs of breaking social norms we present the results of a laboratory experiment as predicted we find that participants are more likely to overstate their performance if this increases the monetary payoff of others than if their reported performance decreases others monetary gains in addition overstatements are lower under an open information policy where each individual s reported performance is made public compared to a closed information policy where participants only learn the average performance of the other participants our findings have several important implications for management accounting research and practice
