futures market equilibrium with heterogeneity and a spot market at harvest abstract this paper studies equilibrium in the futures market for a commodity in a single good economy which is populated by heterogeneous producers and speculators the commodity is traded only in the spot market at harvest whereas futures contracts written on the commodity are traded continuously the model illustrates the role of heterogeneity and non tradeness in a futures market equilibrium the results show that the futures price is driven by aggregate wealth rather than the spot price as in other models and that the futures price process is a simple one which depends on the relative risk process

the minimum variance hedge ratio under stochastic interest rates in an environment where interest rates are stochastic we examine the case of a pure hedger endowed with a fixed position in a long term bond in contrast to conventional wisdom according to which the difference between hedging through forward contracts and futures is immaterial it turns out that the minimum variance hedge ratio using forwards comprises two terms instead of one only when using futures the magnitude of the difference between the two hedge ratios may be important under some plausible assumptions this result is due to the presence of additional interest rate risk that bears on the profit and loss statement associated with the forward position this sheds some additional light on the respective features of forward and futures contracts written on interest rate sensitive securities

a tale of tax policies in open economies recent financial crises in europe as well as the periodic battles in the u s over the debt ceiling point to the importance of fiscal discipline among developed countries this paper develops an open economy model calibrated to the u s and a subset of the emu to evaluate the impact of various permanent tax changes the first set of experiments considers a targeted one percentage point reduction in the government deficit to gdp ratio through raising one of the consumption tax the labor income tax or the capital income tax in terms of welfare the consumption tax is found to be the least costly of the tax increases a second set of experiments looks at deficit neutral tax changes partially replacing the capital income tax with either a higher labor income tax or higher consumption tax and partially replacing the labor income tax with an increased consumption tax reducing reliance on capital income taxation is welfare enhancing although it leads to short term losses reducing labor income taxation improves international competitiveness and is welfare improving

optimal currency risk hedging abstract this paper investigates the optimal hedging strategy of a domestic expected utility maximizer endowed with a temporarily non traded position in a foreign investment the domestic and foreign yield curves the exchange rate between the two involved currencies and the foreign investment value are stochastic and obey fairly general diffusion processes we compare the hedger s optimal strategies using either exchange rate forward contracts or futures contracts for both strategies the optimal number of contracts held can be broken down into several components having clear economic interpretations however while futures contracts are known in such a context to be more difficult to price than their forward counterparts the optimal strategy using them is simpler this is due to the fact that when forward contracts are used incurred profits or losses that accrue to the investor s wealth at each instant are locked in in the forward position up to the contract maturity thus discounting these gains or losses back at the current date brings about an interest rate risk therefore the investor s hedging strategy itself generates an additional risk which in turn induces the need for additional hedging the magnitude of the difference between the two hedge ratios may be significant under a set of plausible assumptions since in general financial markets are not complete the additional interest rate risk cannot be perfectly hedged hence the marking to market mechanism that characterizes futures contracts and allows for the complete elimination of this risk is valuable for risk averse agents

is there an energy efficiency gap many analysts have argued that energy efficiency investments offer an enormous win win opportunity to both reduce negative externalities and save money this overview paper presents a simple model of investment in energy using capital stock with two types of market failures first uninternalized externalities from energy consumption and second forces such as imperfect information that cause consumers and firms not to exploit privately profitable energy efficiency investments the model clarifies that only if the second type of market failure cannot be addressed directly through mechanisms such as information provision energy efficiency subsidies and standards may be merited this chapter therefore reviews the empirical work on the magnitude of profitable unexploited energy efficiency investments a literature which frequently does not meet modern standards for credibly estimating the net present value of energy cost savings and often leaves other benefits and costs unmeasured these problems notwithstanding recent empirical work in a variety of contexts implies that on average the magnitude of profitable unexploited investment opportunities is much smaller than engineering accounting studies suggest finally there is tremendous opportunity and need for policy relevant research that utilizes randomized controlled trials and quasi experimental techniques to estimate the returns to energy efficiency investments and the welfare effects of energy efficiency programs

ramsey optimal tax reforms and real exchange rate dynamics abstract we solve the ramsey optimal tax plan for a small open economy with an endogenously determined real exchange rate the open economy constrains the government s setting of the capital income tax rate since physical capital cannot be dominated in rate of return by foreign assets however the endogenous real exchange rate loosens this constraint relative to a one good open economy model in which the real exchange rate is necessarily fixed we find that the dynamics of the two good small open economy model more closely resemble those of a closed economy model than a one good small open economy model

on the optimal hedge of a nontraded cash position in this paper we focus on the optimal demand for futures contracts by an investor with a logarithmic utility function who attempts to hedge a nontraded cash position when the analysis is conducted in the cash commodity price space we show that the value function associated with the bernoulli investor program is not additively separable thus suggesting that this investor hedges against shifts in the opportunity set as represented by the commodity price by establishing the equivalence between the cash formulation of the problem and the wealth formulation we are able to analyze the problem in the wealth commodity price space in this space we show the additive separability of the value function when the futures settlement price process is perfectly locally correlated with the commodity price process the demand for futures in this instance is composed of a a mean variance term and b a minimum variance component that is a classic feature of models with nontraded assets since the first best nonmyopic optimum is attained however the deviation from a mean variance demand should not be interpreted as the expression of a nonmyopic behavior but rather as an attempt to restore a first best optimum on the other hand when the correlation between the futures price and the underlying commodity price is imperfect in general the value function does not separate additively the first best solution cannot be attained and the optimal futures trading strategy involves a hedging term against shifts in the opportunity set in the classic dynamic portfolio problem the investor selects a trading strategy in risky and riskless assets so as to maximize his or her expected lifetime utility in this environment where all assets can be freely traded the logarithmic investor behaves myopically to the extent that he or she ignores shifts in the opportunity set when making current choices samuelson 271 mossin 24 hakansson 16 merton 22 in particular in models with continuous trading it turns out that the value function corresponding to the investor s program is additively separable in wealth and state variables the implication is that his or her behavior will be myopic i e that his or her demand functions for assets will be of the pure meanvariance efficiency type and in particular will not include any dynamic hedging components that are characteristic of financial markets with shifting opportunities in this paper we investigate the structure of the bernoulli investor s demand functions in the situation where one asset cannot be freely traded in the market

hedging derivative securities and incomplete markets an e arbitrage approach given a european derivative security with an arbitrary payoff function and a corresponding set of underlying securities on which the derivative security is based we solve the optimal replication problem find a self financing dynamic portfolio strategy involving only the underlying securities that most closely approximates the payoff function at maturity by applying stochastic dynamic programming to the minimization of a mean squared error loss function under markov state dynamics we derive recursive expressions for the optimal replication strategy that are readily implemented in practice the approximation error or e of the optimal replication strategy is also given recursively and may be used to quantify the degree of market incompleteness to investigate the practical significance of these e arbitrage strategies we consider several numerical examples including path dependent options and options on assets with stochastic volatility and jumps

the time pattern of hedging and the volatility of futures prices the paper proposes a multi period model of hedging which allows for a futures position to be revised within the cash market holding period within this framework we assess the robustness of the two period theory of hedging when generalized to many periods we characterize the normal time path of a hedge and the way it is affected by the requirement that futures accounts mark to market daily finally we show how the resolution of production uncertainty over time affects hedging behavior and determines the volatility of futures prices in the large literature on hedging in futures markets the principal analytical accounts of hedging are framed in a two trade date setting an agent commits himself now to a future purchase or sale of a good whose cash price later is uncertain this risk is hedged by purchase or sale of an appropriate number of futures contracts and holding this futures position until the cash transaction is realized in the present paper we formulate a multi period model of hedging which allows for the futures position to be revised within the cash market holding period the resulting analysis captures an important institutional reality that is absent in a two trade date model namely the fact that the day to day fluctuations of the futures price will generate a series of random cash flows over the period during which a futures position is held this is due to the requirement that futures accounts mark to market daily within this framework we address a number of issues first we assess the robustness of the two period theory of hedging when generalized to many periods second we characterize the normal time path of a hedge and contrast futures and forward contracts from the perspective of an individual hedger finally we show how the resolution of production uncertainty over time affects hedging behaviour and determines the volatility of futures prices while the literature on asset demand in a multiperiod setting is large futures markets are specifically treated in a limited number of studies grauer and litzenberger 1976 are concerned principally with characterizing the relation of spot and futures prices in a market for a storable periodically produced commodity they offer a rationale for positive stock holding in markets where spot price exceeds the futures price richard and sundaresan 1980 are also concerned primarily with characterizing price behaviour since they posit identical consumers in equilibrium individual holdings of futures are zero there is no hedging activity in the sense that we understand it breeden 1980b analyzes the optimal futures position sizes in a multiperiod setting his framework is more general than ours in that his is a multi good multi asset model where preferences

equilibrium in securities markets with heterogeneous investors and unspanned income risk abstract in a finite time horizon incomplete market continuous time setting with dividends and investor incomes governed by arithmetic brownian motions we derive closed form solutions for the equilibrium risk free rate and stock price for an economy with finitely many heterogeneous cara investors and unspanned income risk in equilibrium the sharpe ratio is the same as in an otherwise identical complete market economy whereas the risk free rate is lower and consequently the stock price is higher the reduction in the risk free rate is highest when the more risk averse investors face the largest unspanned income risk

optimal hedging and equilibrium in a dynamic futures market abstract this paper considers an agent maximizing the expected utility of the sum of the terminal value of a fixed portfolio of spot market assets and the terminal value of a margin account on a futures trading position closed form solutions for the optimal hedging strategy are provided in several special cases

on the international dimension of fiscal policy this paper analyses the international dimension of fiscal policy using a small open economy framework in which the government finances its spending by levying distortionary taxation and issuing non state contingent debt the main finding of the paper is that once the open economy aspect of the policy problem is considered it is not optimal to smooth taxes following idiosyncratic shocks even when prices are flexible and inflation can costlessly act as a shock absorber to restore fiscal equilibrium the presence of a terms of trade externality lead to movements in the tax rate also in contrast with the closed economy the introduction of sticky prices can reduce the optimal volatility of taxes

optimal innovation of futures contracts this article presents a simple model of the innovation of new futures contracts by transaction volume maximizing futures exchanges in incomplete markets under uncertainty with mean variance preferences and proportional transactions costs we characterize the set of nash equilibria for a number of exchanges simultaneously or sequentially choosing contracts the optimal monopolistic contract design is shown to be pareto optimal an example shows the failure of pareto optimality for aparticularnash equilibrium likewise in a monopolistic multiperiod setting an example shows the failure of pareto optimality given an incentive for the exchange to induce turnover

estimating the implicit price of energy efficiency improvements in the residential housing market a hedonic approach abstract in this study a hedonic price model has been used to examine the impact which efficiency improvements have on housing values our study represents an improvement over a previous attempt to examine this issue in that the independent variable used in our analysis is designed to reflect variation in structural efficiency levels among sample homes rather than variation in occupant lifestyles and preferences in addition a flexible functional form is used to prevent bias due to misspecification of the hedonic price equation the study results reveal that efficiency improvements are capitalized into housing prices in des moines iowa at the average efficiency level of homes in the sample an efficiency improvement which results in a 1 decrease in the level of expenditures necessary to maintain the house at 65 f in the average heating season will increase the expected selling price of the house by 11 63 the premium obtained for an equivalent efficiency improvement will be greater than 11 63 in a relatively efficient home and less than 11 63 in a relatively inefficient home without further information concerning the price expectations and discount rates utilized by des moines home buyers and the average remaining life of fuels saving investments in the sample it cannot be determined whether the housing market is pricing fuel savings efficiently regardless of whether or not the implicit price of fuel savings is the outcome of an efficient market information on this implicit price facilitates the estimation of an average resale value of fuel saving investments in addition the results of this study refute the hypothesis that efficiency improving investments are not capitalized into housing prices

on optimal portfolio choice under stochastic interest rates abstract in an economy where interest rates and stock price changes follow fairly general stochastic processes we analyze the portfolio problem of an investor endowed with a non traded cash bond position he can trade on stocks the riskless asset and a futures contract written on the bond so as to maximize the expected utility of his terminal wealth when the investment opportunity set is driven by an arbitrary number of state variables the optimal portfolio strategy is known to contain a pure preference free hedge component a speculative element and merton breeden hedging terms against the fluctuations of each and every state variable while the first two components are well identified and easy to work out the implementation of the last ones is problematic as the investor must identify all the relevant state variables and estimate their distribution characteristics using the martingale approach we show that the optimal strategy can be simplified to include in addition to the pure hedge and speculative components only two merton breeden type hedging elements however large is the number of state variables the first one is associated with interest rate risk and the second one with the risk brought about by the co movements of the spot interest rate and the market prices of risk the implementation of the optimal strategy is thus much easier as it involves estimating the characteristics of the yield curve and the market prices of risk only rather than those of numerous a priori unknown state variables moreover the investor s horizon is shown explicitly to play a crucial role in the optimal strategy design in sharp contrast with the traditional decomposition finally the role of interest rate risk in actual portfolio risk management is emphasized

the nascent market for green real estate in beijing abstract in recent years formal certification programs for rating and evaluating the sustainability and energy efficiency of buildings have proliferated around the world developers recognize that such green labels differentiate products and allow them to charge a price premium china has not formally adopted such rating standards in the absence of such standards developers are competing with each other based on their own self reported indicators of their buildings greenness we create an index using google search to rank housing complexes in beijing with respect to their marketing greenness and document that these green units sell for a price premium at the presale stage but they subsequently resell or rent for a price discount an introduction of a standardized official certification program would help green demanders to acquire units that they desire and would accelerate the advance of china s nascent green real estate market

real options with constant relative risk aversion real options problems have recently attracted much attention worldwide one such problem is how to deal with claims on non traded assets often there is another traded asset which is correlated to the non traded asset and this traded asset is used as a proxy for hedging purposes we introduce a second non traded log brownian asset into the well known merton investment model with power law utility the investor has a claim on units of the non traded asset and the question is how to price and hedge this random payoff the presence of the second brownian motion means that we are in the situation of incomplete markets we propose an approximation to the solution for the optimal reservation price and hedge which is accurate when the position is small in comparison to wealth the resulting loss when a suboptimal proxy strategy is followed is shown to be approximately quadratic in 1

optimal dynamic hedging in unbiased futures markets a discrete time dynamic hedging problem is solved under expected utility maximization and basis risk without imposing a particular parametric form for utility nor assuming normally distributed cash and futures prices the solution is valid for any increasing and strictly concave utility function and for quite general specifications of the joint distribution of cash and futures prices this generality is achieved by restricting the futures market to be unbiased and requiring that the size of the cash position be nonstochastic the dynamic hedging rule can be estimated empirically using similar methods to those used to estimate static hedge ratios

price stability with imperfect financial integration this paper studies whether the international monetary system can be affected by asymmetries in the cross country positions in the international financial markets i e the fact that some countries are large debtors while others are creditors an important channel that is explored is the interaction between international risk sharing and the stabilization role of monetary policy in each country the main finding is that the welfare costs of incomplete markets and the gains of deviating from a policy of price stability are increasing with the cross country asymmetries in the initial net international positions and in particular they become nonnegligible when the persistence of the shocks increases 1 of a permanent shift in steady state consumption for the welfare costs of incomplete markets and 0 2 for the gains of deviating from a policy of price stability when global imbalances become larger optimal monetary policy requires an increase in the volatilities of the real returns on assets and in particular of the nominal interest rates which should happen to be more correlated across countries

redistributive taxation in a simple perfect foresight model abstract we investigate the redistributive potential of capital taxation in an intertemporal maximizing model of capital formation first even unanticipated redistributive capital taxation is severely limited in its effectiveness since it depresses wages second under any convergent redistributive tax policy which maximizes a paretian social objective the capital income tax will converge to zero independent of the factor supply elasticities these results are independent of workers holdings of capital

episodes of war and peace in an estimated open economy model we analyze the effects of world wars on the macroeconomic dynamics of the u s france germany and the uk by means of an estimated open economy model the model allows wars to affect the economy through capital depreciation sovereign default a military draft household preferences and spillovers on other exogenous processes productivity investment trade policy variables if the bulk of fluctuations during war episodes can be explained by the rise in government spending in the u s other factors are crucial in other countries we also discuss the size and state dependence of public spending multipliers and a counterfactual welfare exercise

the value of domestic building energy efficiency evidence from ireland abstract following the transposition of the eu energy performance of buildings directive into irish law all properties offered for sale or to let in ireland are obliged to have an energy efficiency rating this paper analyses the effect of energy efficiency ratings on the sale and rental prices of properties in the republic of ireland using the heckman selection technique we model the decision to advertise the energy efficiency rating of a property and the effect of energy efficiency ratings on property values our results show that energy efficiency has a positive effect on both the sales and rental prices of properties and that the effect is significantly stronger in the sales segment of the property market we also analyse the effect of energy efficiency across different market conditions and we find that the effect of the energy rating is generally stronger where market conditions are worse

the relationship between interest rate differentials and macroeconomic variables a panel data study for european countries abstract based on panel data regressions the relationship between 12 month interest rate differentials and macroeconomic variables is analyzed for nine european countries relative to germany stationarity properties of the variables are examined by tests developed for panel data models the distribution of the test statistic is not normal and is bootstrapped from the sample at hand all significant regression coefficients are estimated with the predicted sign in particular the inflation differential the real income growth differential relative labor costs and the current account have a strong effect on the interest rate differential hence the results indicate that governments have some scope for influencing the interest rate differential by conducting the appropriate macroeconomic policy these results are considerably more optimistic compared to earlier studies where interest rate differentials are frequently measured at 1 month and 3 months maturity included also is an analysis of whether the erm countries have gained more credibility in exchange rate policy through the exchange rate system

zero energy homes are they economically viable whilst net zero energy homes are espoused in many policy circles and many bespoke examples have been constructed to demonstrate their technical feasibility there is a scarcity of evidence demonstrating such a standard would be economically rational particularly for large scale housing development where orientation and aspect may not always be optimal drawing on energy monitoring evidence and construction economics associated with a nearly zero energy housing estate in adelaide australia this paper explores the economic feasibility of the net zero energy home policy in warm temperate climates the results demonstrate that using economic tools and assumptions typically applied for building energy regulatory policy changes net societal economic benefits significantly outweigh costs the clear economic outcomes combined with expected health and productivity benefits from improved levels of thermal comfort should provide security to policy makers to progress home energy standards towards net zero energy performance

futures markets and commodity options hedging and optimality in incomplete markets abstract this paper examines the allocational roles of futures markets and commodity options in multi good and multi period economies in a continuous time model with time additive utilities and homogeneous beliefs trading in unconditional futures contracts the market portfolio and a riskless asset gives any pareto optimal allocation individuals optimal holdings of futures contracts in the continuous time model are related to their consumption bundles and to their risk tolerances it is shown that both hedging and reverse hedging behavior are possible in the general model with discrete trading options on portfolios of commodity options are shown to permit any unconstrained pareto optimal allocation

theory measurement and calibration of macroeconomic models abstract calibration has become a standard tool of macroeconomics this paper extends and refines the calibration methodology along several important dimensions first accounting for home production is important both in measuring calibration targets and in organizing the data in a model consistent fashion for this reason thinking about home production is important even if the model under consideration does not include home production second investment specific technological change is included because of its strong balanced growth parameter restrictions third the measurement strategy is laid out as transparently as possible so that others can easily replicate the underlying calculations the data and calculations used in this paper are available at http clevelandfed org research models rbc index cfm

doing well by doing good green office buildings this paper provides the first credible evidence on the economic value of the certification of green buildings in the commercial sector value derived from impersonal market transactions rather than engineering estimates we match publicly available information on the addresses of energy star and leed rated office buildings to a commercial data source detailing the characteristics of u s office buildings and their rental rates we analyze the micro data on 694 certified green buildings and on 7489 other office buildings located within a quarter mile of the certified buildings we find systematic evidence that rents for green offices are about two percent higher than rents for comparable buildings located nearby effective rents i e rents adjusted for the occupancy levels in office buildings are about six percent higher in green buildings than in comparable office buildings nearby at prevailing capitalization rates conversion of the average non green building to an equivalent green building would add more than 5 million in market value these results are robust to the statistical models employed

monetary policy and welfare in a small open economy this paper analyzes optimal monetary policy in a small open economy featuring monopolistic competition and nominal rigidities it shows that the utility based loss function for this economy can be written as a quadratic expression of domestic inflation output gap and real exchange rate the presence of an internal monopolistic distortion and a terms of trade externality drives optimal policy away from domestic inflation targeting and affects the optimal level of exchange rate volatility when domestic and foreign goods are close substitutes for each other the optimal policy rule implies lower real exchange rate volatility than a domestic inflation targeting regime the reverse is true when the elasticity of substitution between goods is low

spreading currency forwards why and how abstract in this paper we have adopted a continuous time framework in which a hedger has a currency risk sensitive non traded cash position the hedger has the opportunity to hedge against risk by using two currency forward contracts that differ only in their maturities the hedger is able to reach a perfect hedge of his non traded position by using only two currency forward contracts with different maturities even though four sources of uncertainty drive the international economy this perfect hedge is reached by spreading forward contracts where the hedger is short in the nearby contract and long in the deferred contract this strategy is easy to implement since no parameter has to be estimated empirically when the hedger is a price taker finally the analysis has been extended to currency futures contracts we show in explicit terms how the marking to market of futures positions affects the spreading strategy

managing risk in multi asset class multimarket central counterparties the core approach abstract multi asset class multimarket central counterparties ccps are becoming less uncommon as a result of merges between specialized single asset class single market ccps and market demands for greater capital efficiency yet traditional ccp risk management models often lack the necessary sophistication to estimate potential losses relative to the closeout process of a defaulter s portfolio in a multi asset class multimarket environment as a result multi asset class multimarket ccps usually rely on a simplified silo approach for risk calculation which not only fails to deliver efficiency but may also increase systemic risk the core closeout risk evaluation approach on the other hand provides conceptual and mathematical tools necessary for robust and efficient central counterparty risk evaluation in multi asset class and multimarket environments acknowledging the portfolio dynamics involved in the closeout process as well as important real life market frictions

optimal fiscal and monetary policy in an economy without capital abstract this paper is concerned with the structure and time consistency of optimal fiscal and monetary policy in an economy without capital in a dynamic context optimal taxation means distributing tax distortions over time in a welfare maximizing way for a barter economy our main finding is that with debt commitments of sufficiently rich maturity structure an optimal policy if one exists is time consistent in a monetary economy the idea of optimal taxation must be broadened to include an inflation tax and we find that time consistency does not carry over an optimal inflation tax requires commitment by rules in a sense that has no counterpart in the dynamic theory of ordinary excise taxes the reason time consistency fails in a monetary economy is that nominal assets should from a welfare maximizing point of view always be taxed away via an immediate inflation in a kind of capital levy this emerges as a new possibility when money is introduced into an economy without capital

seasonal patterns of futures hedging and the resolution of output uncertainty abstract optimal futures hedging is examined in a two good model with stochastic output and sequential information arrival a producer s optimal hedge depends on demand elasticity sensitivity of his output to weather his correlation with aggregate output and how rapidly his output uncertainty is resolved relative to other producers during different seasonal periods because regional output uncertainties are resolved at different times the optimal futures position of a grower will commonly reverse in direction during the crop year a producer with non stochastic output who faces price risk arising from demand shocks may remain unhedged or even maintain a long position

ramsey policies in a small open economy with sticky prices and capital this paper analyzes jointly optimal fiscal and monetary policies in a small open economy with capital and sticky prices we allow for trade in consumption goods under perfect international risk sharing we consider balanced budget fiscal policies where authorities use distortionary taxes on labor and capital together with monetary policy using the nominal interest rate first as long as a symmetric equilibrium is considered the steady state in an open economy is isomorphic to that of a closed economy second whereas sticky prices allocations are almost indistinguishable from flexible prices allocations the open economydimension delivers results that are qualitatively similar to those of a closed economy but with significant quantitative changes fluctuations in terms of trade implied by complete international financial markets affect i consumption through changes in the consumption price index cpi ii hours through changes in the cpi based real wage and iii capital accumulation through the relative price of capital goods these wedges affect the volatility and persistence of optimal tax rates and resulting allocations are quite different as compared to a closed economy

optimal spreading when spreading is optimal abstract this paper assumes an investor who has a non traded position operating in a stochastic interest rates environment the investor trades continuously either distinct futures contracts or distinct forward contracts in order to maximize his expected utility of terminal wealth in order to reach the welfare level of the first best optimum the investor must incorporate into his portfolio either two distinct futures contracts or two distinct forward contracts the optimal forward contracts dynamic spreading strategy has two components a speculative component and a minimum variance hedging component the minimum variance hedging component is composed of a short position in the nearby contract and a long position in the deferred contract the speculative component serves to replicate the growth optimum portfolio the speculative component is composed of a short position in the contract which is the most negatively correlated with the growth optimum portfolio and a long position in the other contract the marking to market procedure of the futures positions forces the investor to hold less futures contracts than the corresponding forward contract positions the analysis is also extended to incomplete markets and to inter market spreading

debt hangover in the aftermath of the great recession following the great recession u s government debt levels exceeded 100 of output we develop a macroeconomic model to evaluate the role of various shocks during and after the great recession labor market shocks have the greatest impact on macroeconomic activity we then evaluate the consequences of using alternative fiscal policy instruments to implement a fiscal austerity program to return the debt output ratio to its pre great recession level our welfare analysis reveals that there is not much difference between applying fiscal austerity through government spending the labor income tax or the consumption tax using the capital income tax is welfare reducing

optimal dynamic hedging decisions for grain producers the application of an optimal dynamic hedging model was explored for a county in north carolina corn yield harvest corn basis and december corn futures prices were forecast the forecasts were used to calculate optimal dynamic hedge positions when the hedge position was updated infrequently commissions were only slightly higher than commissions from a fixed hedge gains from updating the hedge position over the corn growing season were not substantial compared to a fixed hedge position

dynamic speculation and hedging in commodity futures markets with a stochastic convenience yield the main objective of this paper is to address in an a continuous time framework the issue of using storable commodity futures as vehicles for hedging purposes when in particular the convenience yield as well as the market prices of risk evolve randomly over time following the martingale route and by operating a suitable constant relative risk aversion utility function crra specific change of numeraire we solve the investor s dynamic optimization program to obtain quasi analytical solutions for optimal demands which can be expressed in terms of two discount bonds traded and synthetic contrary to the existing literature we explicitly derive the individual optimal proportions invested in the spot commodity in a discount bond and in the futures contracts which can be computed in a simple recursive way we suggest various decompositions allowing an investor to assess the sensitivity of the optimal demands to the state variables and to specify the role played by each risky asset empirical evidence shows that the convenience yield has a strong impact on the speculation and hedging positions and the interaction among time varying risk premia determines the magnitude and the sign of these positions

willingness to pay for energy saving measures in residential buildings this paper uses a choice experiment to evaluate the consumers willingness to pay for energy saving measures in switzerland s residential buildings these measures include air renewal ventilation systems and insulation of windows and facades two groups of respondents consisting respectively of 163 apartment tenants and 142 house owners were asked to choose between their housing status quo and each one of the several hypothetical situations with different attributes and prices the estimation method is based on a fixed effects logit model the results suggest that the benefits of the energy saving attributes are significantly valued by the consumers these benefits include both individual energy savings and environmental benefits as well as comfort benefits namely thermal comfort air quality and noise protection

nontraded assets in incomplete markets pricing and portfolio choice this paper examines portfolio choice and asset pricing when some assets are nontraded for instance when a country cannot trade claims to its output on world capital markets when a government cann

the laffer curve revisited abstract laffer curves for the us the eu 14 and individual european countries are compared using a neoclassical growth model featuring constant frisch elasticity cfe preferences new tax rate data is provided the us can maximally increase tax revenues by 30 with labor taxes and 6 with capital taxes we obtain 8 and 1 for the eu 14 there 54 of a labor tax cut and 79 of a capital tax cut are self financing the consumption tax laffer curve does not peak endogenous growth and human capital accumulation affect the results quantitatively household heterogeneity may not be important while transition matters greatly

the economics of green building we analyze the economics of green building finding that recent increases in the supply of green buildings and the volatility in prop erty markets have not affected the returns to green buildings we then analyze a large cross section of office buildings demonstrating that eco nomic returns to energy efficient buildings are substantial finally we relate the economic premiums for green buildings to their relative effi ciency in energy use the attributes rated for thermal efficiency as well as sustainability contribute to premiums in rents and asset values among green buildings increased energy efficiency is fully capitalized into rents and asset values

explicit solutions to an optimal portfolio choice problem with stochastic income abstract this paper solves in closed form the optimal portfolio choice problem for an investor with negative exponential utility over terminal wealth facing imperfectly hedgeable stochastic income the returns on income and the stock are imperfectly correlated so the market is incomplete we identify how an investor adjusts their merton rev econ statist 51 1969 247 portfolio of the stock and riskless asset via an intertemporal hedging demand in reaction to the stochastic income under general assumptions on the process governing the income the sign of the hedging demand is the opposite of the sign of the correlation between the income and stock the optimal portfolio in the stock is long stock if the risk premium is positive and correlation negative and short if these signs are reversed specializing in turn to normally distributed income and lognormally distributed income with or without mean reversion the effect of a number of parameters on the optimal portfolio in the stock can be studied when the risk premium on the stock and correlation have opposite signs the optimal portfolio decreases in magnitude with risk aversion unhedgeable variance of income and time and increases in magnitude with the magnitude of correlation under both the lognormal without mean reversion and normal models for income these relationships do not necessarily hold if the signs on the risk premium and correlation are the same in particular the optimal portfolio is not necessarily monotone in risk aversion violating well known static results in models without income when income follows a lognormal model with mean reversion more complicated behavior can occur for instance the optimal portfolio does not have to be monotonic in time regardless of the signs of correlation and the risk premium

optimal futures innovation in a dynamic economy the discrete time case abstract we study the optimal futures innovation in a dynamic economy and investigate how the results obtained in a static economy should be modified due to the possibility of dynamic trading we analyze three different notions of ex ante optimality depending on the authority s ability to redistribute wealth among the investors and characterize the optimal futures innovation in each sense journal of economic literature classification numbers d52 d60 g10

optimal hedging in a dynamic futures market with a nonnegativity constraint on wealth abstract this paper examines the issue of optimal hedging demands for futures contracts from an investor who cannot freely trade his portfolio of primitive assets in the context of lognormal rather than normal returns and of a constant absolute risk aversion utility function in this context the nonnegativity constraint on wealth is binding and the optimal hedging demands are not identical with those encountered in the bulk of the literature which has largely overlooked this problem negative results concerning the derivation of equilibrium in the futures markets and the computation of the open interests then follow

the impact of energy labels and accessibility on office rents abstract energy consumption in the commercial property sector offers an important opportunity for conserving resources in this study we evaluate the financial implications of two elements of sustainability energy efficiency and accessibility in the market for commercial real estate an empirical analysis of some 1100 leasing transactions in the netherlands over the 2005 2010 period shows that buildings designated as inefficient with an eu energy performance certificate d or worse command rental levels that are some 6 5 percent lower as compared to energy efficient but otherwise similar buildings labeled a b or c furthermore this study shows that office buildings in multi functional areas with access to public transport and facilities achieve rental premiums over mono functional office districts for policymakers the results documented in this paper provide an indication on the effectiveness of the eu energy performance certificate as a market signal in the commercial property sector the findings documented here are also relevant for investors in european office markets as the importance of energy efficiency and locational diversification is bound to increase following stricter environmental regulation and changing tenant preferences

dynamic hedging with uncertain production this paper provides a closed form rule for dynamic hedging with production uncertainty the rule is obtained by considering a discret e time control problem in the limit as the interval between hedging opportunities goes to zero price may be expected to increase or decrease so that a speculative motive is present in the absence of this motive and of discounting the optimal hedge is myopic for a given expected rate of change in price the hedge may be expected to rise or fall depending on the degree of risk aversion copyright 1988 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

optimal taxation of capital income in general equilibrium with infinite lives this paper analyzes the optimal tax on capital income in general equilibrium models of the second best agents have infinite lives and utility functions which are extensions from the koopmans form the population is heterogeneous the important property of the models is the equality between the social and the private discount rates in the long run i find that the optimal tax rate is zero in the long run for a special case of additively separable utility functions i then determine the tax rates along the dynamic path and conditions that are sufficient for the local stability of the steady state

the energy efficiency gap what does it mean abstract as renewed attention has been given by policy makers to energy conservation issues it has frequently been asserted that an energy efficiency gap exists between actual and optimal energy use the critical questions is how to define the optimal level of energy efficiency this paper seeks to disentangle some confusing strands of argument that are frequently brought to bear on this question by identifying the major conceptual issues that determine the set of feasible answers we identify five separate and distinct notions of optimality the economists economic potential the technologists economic potential hypothetical potential the narrow social optimum and the true social optimum each of these has associated with it a corresponding definition of the energy efficiency gap our analysis demonstrates that necessary preconditions for identifying the right measure of the energy efficiency gap include understanding and disentangling market failure and non market failure explanations for the gradual diffusion of energy efficient technologies

real exchange rate adjustment in and out of the eurozone it is often suggested that currency unions unduly inhibit the efficient adjustment of real exchange rates recently this has been seen as a key failure of the eurozone this paper presents evidence that throws doubt on this conclusion our evidence suggests that real exchange rate movement within the eurozone was at least as compatible with efficient adjustment as the behavior of real exchange rates for the floating rate countries outside the eurozone this interpretation is consistent with a model in which nominal exchange rate movements give rise to persistent deviations from the law of one price in traded goods

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

effects of energy performance certificates on investment a quasi natural experiment approach incomplete information may be one reason why some households do not invest in energy efficiency even though it would benefit them to do so energy performance certificates epcs have been promoted

dynamic scoring a back of the envelope guide abstract this paper uses the neoclassical growth model to examine the extent to which a tax cut pays for itself through higher economic growth the model yields simple expressions for the steady state feedback effect of a tax cut the feedback is surprisingly large for standard parameter values half of a capital tax cut is self financing the paper considers various generalizations of the basic model including elastic labor supply general production technologies departures from infinite horizons and non neoclassical production settings it also examines how the steady state results are modified when one considers the transition path to the steady state

the international ramifications of tax reforms supply side economics in a global economy this paper studies tax reforms in a dynamic model of a global economy calibrated to current u s and european tax policies world capital markets add consumption smoothing and income redistribution effects that alter closed economy predictions in the absence of taxes on foreign interest welfare gains of eliminating u s income taxes are enlarged by up to 34 percent at the expense of european losses caused by transitional declines in consumption and leisure and a permanent capital outflow in contrast if foreign interest is taxed the same tax reform reduces u s welfare 0 7 percent and increases european welfare 1 8 percent copyright 1998 by american economic association
