some nonlinear tax effects on asset values and investment decisions under uncertainty abstract tax system nonlinearities are often ignored but with uncertainty may have important implications for the magnitude and direction of tax effects this paper studies a particular nonlinear tax rule the policy subsidizes asset values but may discourage some investments and encourage earlier shutdown of some projects the marginal effective tax rate varies with project risk furthermore a corporate cash flow tax can encourage investment due to interactions with the nonlinear policy the paper also presents a general statement of the stochastic equilibrium valuation method which can be used to analyze other nonlinear taxes numerical examples demonstrate computational feasibility

the structure of multi period employment contracts with incomplete insurance markets this paper examines the structure of multi period employment contracts in an economy with identical workers when only incomplete insurance is provided against job related contingencies the incompleteness of insurance markets stems from an asymmetry of information between the worker and the insurer in this situation the employment contract will provide implicit insurance by paying workers less than their marginal product during some periods and more during others the paper explores how the characteristics of such contracts are altered by increases in uncertainty worker risk aversion hiring costs and the amount of specific and general training provided a sequel to this paper examines the efficiency properties of such contracts this abstract was borrowed from another version of this item

wage profiles and imperfect capital markets a positive analysis this paper examines the structure of long term employment contracts when labor is mobile and risk averse employers are unable to monitor workers outside job offers workers cannot borrow against future income and workers productivity is increasing in the length of service with the long term employer workers are then liquidity constrained and the contract trades off consumption smoothing against efficiency in turnover in contrast to previous papers which have examined this problem this paper provides a continuous time formulation that permits a detailed characterization of the properties of the wage profile

electricity supply employment and real gdp in india evidence from cointegration and granger causality tests abstract this study probes nexus between electricity supply employment and real gdp for india within a multivariate framework using autoregressive distributed lag ardl bounds testing approach of cointegration long run equilibrium relationship has been established among these variables for the time span 1970 71 to 2005 06 the study further establishes long and short run granger causality running from real gdp and electricity supply to employment without any feedback effect thus growth in real gdp and electricity supply are responsible for the high level of employment in india the absence of causality running from electricity supply to real gdp implies that electricity demand and supply side measures can be adopted to reduce the wastage of electricity which would not affect future economic growth of india

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

the relationship between economic growth and electricity consumption from renewable and non renewable sources a study of turkey abstract the main objective of this study is to analyze the short and long run estimates as well as the causality relationships between economic growth gr electricity consumption from renewable sources relc and electricity consumption from non renewable sources nrelc for turkey in a multivariate model wherein capital k and labor l are included as additional variables using the autoregressive distributed lag ardl approach to cointegration the johansen cointegration test and the gregory hansen cointegration test with structural break we show that gr relc nrelc k and l are cointegrated although nrelc has a long run positive effect on gr the long run estimate of relc is negative but insignificant at 5 level of significance the granger causality test based on the vector error correction model reveals the evidence of neutrality hypothesis between relc and gr and between nrelc and gr in turkey in the short run in addition the granger causality runs from relc nrelc k and l to gr as well as from gr relc k and l to nrelc in the long run which supports the existence of growth hypothesis between relc and gr and feedback hypothesis between nrelc and gr in the long run it is advised that policy makers in the turkish government should continue to reduce the share of electricity consumption from renewable sources and encourage the usage of electricity from non renewable sources to have sustainable long run growth rates it is also essential to promote the investment projects to increase the efficiency of electricity generation from non renewable sources

the relationship between urbanization energy use and carbon emissions evidence from a panel of association of southeast asian nations asean countries abstract this study uses annual data to detect the nexus between urbanization energy use and carbon emissions in a panel of association of southeast asian nations asean countries spanning the period 1980 2009 the study contributes to the increasing empirical literature by investigating the effects of urbanization and detecting causal links between the variables results from the pedroni panel cointegration tests show evidence for the existence of a long term equilibrium relationship between urbanization energy use and carbon emissions for the asean countries using the panel fully modified ordinary least squares technique the effect of urbanization on carbon emissions is further revealed i e a 1 rise in urban population results in a 0 20 increase in carbon emissions unilateral short run causal relationships from urbanization to energy use and from urbanization to carbon emissions have been found by granger causality tests also the results clearly indicate that in the long term urbanization together with energy use granger causes carbon emissions the paper concludes with main findings and provides recommendations toward rational planning of urban development and energy efficiency improvement strategies for the asean countries

causality relationship between electricity consumption and gdp in bangladesh in this paper we examine the causal relationship between the per capita electricity consumption and the per capita gdp for bangladesh using cointegration and vector error correction model our results show that there is unidirectional causality from per capita gdp to per capita electricity consumption however the per capita electricity consumption does not cause per capita gdp in case of bangladesh the finding has significant implications from the point of view of energy conservation emission reduction and economic development

an option pricing approach to evaluating petroleum projects abstract option pricing applications in capital budgeting decisions are still in the development stage this paper uses concepts and methods from option pricing theory to evaluate real projects rather than financial ones within a petroleum projects context such real options include development and operations of satellite fields break even values of incremental capacity and flexibility value with compound development and operations options the option pricing results may be quite different from those obtained by traditional capital budgeting and decision tree approaches some related papers on real options are also briefly noted

impacts of urbanization on renewable energy consumption in china abstract in this paper we used the logarithmic mean divisia index method to investigate the impact of urbanization on renewable energy consumption growth recg the growth in renewable energy consumption is attributed to the urbanization effect energy mix effect energy intensity effect economic effect and population effect recg can be roughly divided into the slow growth stage the fluctuant growth stage and the accelerated growth stage the results showed that the energy mix effect economic effect and population effect positively affected recg however a significantly negative relationship was found between energy intensity and recg furthermore the contribution of urbanization differed in recg stages and urbanization contributed more to the total energy consumption growth than to recg this study would thus provide policymakers with insights about the link between urbanization and renewable energy consumption

on the causal dynamics between hydroelectricity consumption and economic growth in latin america countries abstract the aim of this study is to examine the relationship between hydroelectricity consumption and economic growth in seven latin america countries including argentina brazil chile colombia ecuador peru and venezuela the analysis is conducted within a neoclassical model involving capital and labour force for the period of 1970 2012 we utilize a recently developed cointegration test to investigate the long run relationship in the variables having established that the variables are cointegrated the results indicate long run bidirectional causality between hydroelectricity consumption and economic growth in argentina and venezuela there is evidence for long run unidirectional causality from hydroelectricity consumption to economic growth in brazil chile colombia ecuador and peru the long run coefficients from the regression analyses suggest that hydroelectricity consumption positively affect the economies of these latin american countries however limited evidence of causality between the two variables is found in the short run the ensuing policy implications of the findings are discussed

electricity consumption and economic growth in china abstract this paper applies the error correction model to examine the causal relationship between electricity consumption and real gdp for china during 1971 2000 our estimation results indicate that real gdp and electricity consumption for china are cointegrated and there is unidirectional granger causality running from electricity consumption to real gdp but not vice versa in order to overcome the constraints on electricity consumption the chinese government has to speed up the nation wide interconnection of power networks to upgrade urban and rural distribution grids and to accelerate rural electrification

electricity as a traded good abstract electric power has traditionally been classified as a non traded good produced and consumed within the country of origin more recently electricity has been traded across national borders and in certain cases viz bhutan has been the dominant export in other situations it is used to repay debts owed to neighboring countries this paper investigates the role of electricity as the primary export analyzes its valuation and then goes on to evaluate the impact on the terms of trade we conclude that in the medium term the electric power exporting economy would be better off developing its manufacturing sector to diversify its exposure and to protect its trade interests the case of bhutanese hydro electricity exports to india is studied and the change in trade advantage with every increase in power tariff is ascertained it is found that a 1 26 annual increase in non food consumer prices is correlated with a 1 increase in electricity export tariff while the causality from electric power tariff to indian manufactures prices is not established statistically a change in manufactures prices feeding back into consumer prices in bhutan is statistically significant suggestions are offered for bhutan to reduce dependence on indian imports and to diversify its export market exposure

option pricing when the underlying asset earns a below equilibrium rate of return a note in their classic paper black and scholes 2 present two derivations of the european call option pricing formula the first which we will refer to as the replication derivation relies on the fact that the returns from the option can be replicated by holding a continuously revised position in the underlying asset and bonds this implies that if an option is not priced according to the blackscholes formula there is a sure profit to be made by some combination of either short or long sales of the option and underlying asset this argument is seemingly independent of considerations relating to capital market equilibrium the second derivation which we will call the equilibrium derivation evolves from the requirement that the option earn an expected rate of return commensurate with the risk involved in holding the option as an asset this note considers the pricing of a call option on an asset which earns an expected rate of return lower than that necessary to induce investors to hold it we show in this case that even if the replication strategy is feasible it is inefficient a consequence of this is that the correct option pricing formula is different than the black scholes formula unlike the black scholes formula our formula requires as an input the difference between the expected rate of return on the underlying asset and that expected rate of return which would be required to induce holding of the asset other papers have made a similar point constantinides 3 and cox et al 4 have argued that in equilibrium the prices of traded contingent claims must satisfy a partial differential equation which is identical to the black scholes partial differential equation only when the underlying asset pays no dividends and earns a rate of return sufficient to induce holding of the asset more recently ingersoll 5 has noted that commodities often pay a nonpecuniary service yield the value of which must be taken into account in deriving the option price none of these authors however explain why the black scholes formula is sometimes inappropriate the purpose of this note is to demonstrate why the black scholes formula needs modification even if replication is feasible we provide an intuitive derivation of the correct formula and discuss why divergences of the equilibrium price from the black scholes formula do not result in arbitrage opportunities

estimation of electricity demand function for algeria revisit of time series analysis abstract this paper aims to empirically re examine whether economic growth has effect on electricity consumption for algerian economy we have incorporated urbanization and trade openness in electricity demand function as additional determinants of electricity consumption for the period of 1971 2012 for empirical purpose we have applied the recently developed combined cointegration test proposed by bayer and hanck 2013 and bounds testing approach to cointegration by pesaran et al 2001 for establishing the cointegration between the variables by accommodating structural breaks the results expose that income growth leads to higher electricity demand along with urbanization being another major contributing factor of rising electricity demand in contrast trade openness leads to reduce electricity demand the causal association between the variables is further examined with the application of innovation accounting approach of vector autoregressive var the empirical evidence indicates the presence of the neutral effect between income growth and electricity use urbanization causes electricity use and electricity use causes urbanization in granger sense

modeling the response to exogenous shocks the capital uplift rate in petroleum taxation abstract we show how a recent drop in the norwegian capital uplift rate by two percentage points changes optimal field design and reduces field value for shareholders although optimal design changes considerably and value drops by 12 the ability to reoptimize design after the shock is worth only 1 5 of field value this evidence suggests that large behavioral effects of a shock do not necessarily imply large value effects making it less important to always account for the taxpayers response the valuation error in such cases may be moderate if one instead uses the simplifying and widespread assumption of unresponsive taxpayers

a parsimonious model of tax avoidance and distortions in petroleum exploration and development abstract we present a simple model of petroleum exploration and development that can be applied to study the performance of alternative tax systems and identify potential distortions although the model is highly simplified it incorporates many factors and some of the key tradeoffs that would influence an investor s investment behavior the model recognizes the role of enhanced oil recovery and treats the impact of taxation on exploration and development in an integrated manner consistent with an investor s joint optimization of investments at both stages of the process the model is simple and user friendly which facilitates application to a broad range of problems

electricity consumption and economic growth in nigeria a revisit of the energy growth debate abstract this paper examines the dynamic causal linkages between electricity consumption and economic growth in nigeria within a trivariate vecm for the period 1971 2011 the paper obviates the variable omission bias and the use of cross sectional techniques that characterise most existing studies the results show that there is a distinct causal flow from electricity consumption to economic growth both in the short run and in the long run this finding supports the electricity led growth hypothesis that has been conjectured in the literature the paper urges policy makers in nigeria to implement policies which enhance the generation and consumption of electricity in order to engineer economic growth appropriate monetary policies must also be put in place in order to moderate inflation thus enhancing growth

electricity consumption from renewable and non renewable sources and economic growth evidence from latin american countries abstract this study explores the effect of renewable and non renewable electricity consumption on economic growth in 18 latin american countries to achieve the goal of this study a panel gross domestic product gdp model was constructed taking the period 1980 2010 into account from the pedroni cointegration test results it was found that renewable electricity consumption non renewable electricity consumption labor gross fixed capital formation and total trade are cointegrated moreover the panel dynamic ordinary least squares dols test results revealed that all above the mentioned variables have a long run positive effect on gdp growth in the investigated countries the vector error correction vec granger causality model results revealed the existence of feedback causality between the variables the results of the study indicated that renewable electricity consumption is more significant than non renewable electricity consumption in promoting economic growth in the investigated countries in the long run and the short run based on the results of this study it is recommended that the investigated countries should increase their investment on renewable energy projects to increase the role of electricity consumption from renewable sources in addition it is essential that these countries should reduce their non renewable electricity consumption by increasing their energy efficiency and implementing energy saving projects by applying these recommendations these countries would be able to mitigate global warming and reduce their dependency on fossil fuel to increase their energy security

petroleum taxation under uncertainty contingent claims analysis with an application to norway abstract contingent claims analysis provides a useful tool for analysing the value of tax claims and of companies after tax values under uncertainty the method is presented and applied to the analysis of how norwegian petroleum taxes affect company behaviour few results can be derived analytically a numerical approach is suggested with a stylized description of production possibilities the norwegian taxes are found to have strong distortionary effects the relation to other methods and problems connected with the application are discussed

trivariate causality between economic growth urbanisation and electricity consumption in angola cointegration and causality analysis abstract this paper investigates the causal relationship between economic growth urbanisation and electricity consumption in the case of angola while utilizing the data over the period of 1971 2009 we have applied lee and strazicich 2003 the review of economics and statistics 63 1082 1089 2004 working paper department of economics appalachian state university unit root tests to examine the stationarity properties of the series using the gregory hansen structural break cointegration procedure as a complement we employ the ardl bounds test to investigate long run relationships the vecm granger causality test is subsequently used to examine the direction of causality between economic growth urbanisation and electricity consumption our results indicate the existence of long run relationships we further observe evidence in favour of bidirectional causality between electricity consumption and economic growth the feedback hypothesis is also found between urbanisation and economic growth urbanisation and electricity consumption granger cause each other we conclude that angola is energy dependent country consequently the relevant authorities should boost electricity production as one of the means of achieving sustainable economic development in the long run

electricity consumption growth nexus the case of malaysia abstract the goal of this paper is to model the relationship between electricity consumption and real gross domestic product gdp for malaysia in a bivariate and multivariate framework we use time series data for the period 1971 2003 and apply the bounds testing approach to search for a long run relationship our results reveal that electricity consumption real gdp and price share a long run relationship the results of the autoregressive distributed lag ardl estimates of long run elasticity of electricity consumption on gdp are found to be around 0 7 and statistically significant finally in the short run the results of the causality test show that there is a unidirectional causal flow from electricity consumption to economic growth in malaysia from these findings we conclude that malaysia is an energy dependent country leading us to draw some policy implications this paper adds support and validity thus reducing the policy makers concern on the ambiguity of the electricity and growth nexus in malaysia

the relationship between electricity consumption electricity prices and gdp in pakistan abstract this study analyzes the relationship among electricity consumption its price and real gdp at the aggregate and sectoral level in pakistan using annual data for the period 1960 2008 the study finds the presence of unidirectional causality from real economic activity to electricity consumption in particular growth in output in commercial manufacturing and agricultural sectors tend to increase electricity consumption while in residential sector growth in private expenditures is the cause of rising electricity consumption the study concludes that electricity production and management needs to be better integrated with overall economic planning exercises this is essential to avoid electricity shortfalls and unplanned load shedding

labor turnover wage structures and moral hazard the inefficiency of competitive markets a multiperiod general equilibrium model of the labor market is developed in which risk averse workers are faced with job related uncertainty and labor turnover is costly if a worker is unlucky and suffers a bad job match he quits and joins another firm hoping that he will like its work environment more because the quality of a job match is unobservable workers cannot insure against the risk of a bad match the firm provides implicit insurance against job dissatisfaction typically by paying workers more than their net marginal products in their early years with the firm and less subsequently since the probabilities of the insured against events the quit rates over time are affected by the amount of such insurance provided this implicit insurance is characterized by moral hazard individuals quit when in the absence of insurance they would not the equilibrium contract balances out efficiency in risk bearing with efficiency in turnover incentives we show that the equilibrium contract is not con
