Global Warming Policy and the Pennsylvania Economy: A Computable General Equilibrium Analysis

Most studies of the impacts of global warming policy have been performed at the national level. However, national averages obscure the fact that some regions may be affected much more than others. We formulated a regional computable general equilibrium model to analyze the impact of a carbon tax on the Pennsylvania economy. The model incorporates special features relating to labor mobility, trade and energy substitution for this purpose. Our results indicate significant negative overall impacts on the Pennsylvania economy, primarily because it is a major producer and user of fossil fuels, especially coal, and because it is highly industrialized. Sensitivity analyses on key parameters and model assumptions indicate that our results are robust.

Rational expectations for large CGE models: A practical algorithm and a policy application

We describe a simple iterative method for solving large dynamic CGE models under rational expectations. Details are given for Australia's MONASH model but the approach applies to a wide range of CGE models. The method is automated in the RunMONASH Windows software, putting CGE modelling under rational expectations within the reach of non-specialist modellers. We provide an illustrative application in which MONASH results under rational expectations are compared with results under static expectations. The application and supporting software can be downloaded. Results from the application are interpreted in terms of elementary economic mechanisms.

A TEST OF A GENERAL EQUILIBRIUM STOCK OPTION PRICING MODEL

An empirical version of the Cox, Ingersoll, and Ross (1985a) call option pricing model is derived, assuming execution price uncertainty in the options market. the pricing restrictions come in the form of moment conditions in the option pricing error. These can be estimated and tested using a version of the method of simulated moments (MSM). Simulation estimates, obtained by discretely approximating the risk-neutral processes of the underlying stock price and the interest rate, are substituted for analytically unknown call prices. the asymptotics and other aspects of the MSM estimator are discussed. the model is tested on transaction prices at 15-minute intervals. It substantially outperforms the Black-Scholes model. the empirical success of the Cox-Ingersoll-Ross model implies that the continuous-time interest rate implicit in synchronous transaction quotes of 90-day Treasury-bill futures contracts is an-albeit noisy-proxy for the instantaneous volatility on common stock. the process of the instantaneous volatility is found to be close to nonstationary. It is well approximated by a heteroskedastic unit-root process. With this approximation, the Cox-Ingersoll-Ross model only slightly overprices long-maturity options.     

Tax Interaction Effects,Environmental Regulation,and “Rule of Thumb” Adjustments to Social Cost

Preexisting distortions in factor markets complicate the estimation of the social welfare effects of regulatory interventions. The existence of these tax interaction effects (TIEs) suggests that general equilibrium (GE) approaches should be used to evaluate regulatory policies. However, formal GE analysis is not always feasible for the numerous environmental regulations proposed by federal, state, and local agencies. The question addressed in this paper is whether an empirically based rule of thumb upward adjustment factor is appropriate to properly scale social cost estimates in environmental policy. We argue that such rule of thumb adjustments are significantly less reliable than estimates based on a detailed general equilibrium analysis because of the uncertainty about both the magnitude and sign of the social cost distortion. In addition to addressing this question, the paper gives an overview of TIEs and their relevance to environmental policy.     

GENERAL EQUILIBRIUM WITH CONSTANT RELATIVE RISK AVERSION AND VASICEK INTEREST RATES1

We consider a pure exchange economy consisting of a single risky asset whose dividend drift rate is modeled as an Omstein-Uhlenbeck process, and a representative agent with power-utility who, in equilibrium, consumes the dividend paid by the risky asset. Endogenously determined interest rates are found to be of the Vasicek (1977) type the mean and variance of the equilibrium stock price are stochastic and have mean-reverting components A closed-form solution for a standard call option is determined for the case of log-utility. Equilibrium values have interesting implications for the equity premium puzzle observed by Mehra and Prescott (1985)     

GATT第20条引言在环境贸易争端中的司法寓意和最新发展

GATT第20条(b)款和(g)款常为成员方在环境贸易争端中援引,但往往因无法满足第20条引言对环保例外条款的限制而在争端中失利。引言作为对例外条款的限制,防止成员方滥用贸易限制措施,其司法含义自海虾—海龟案的诠释后,在巴西翻新轮胎案中又得到进一步丰富,中国政府应关注引言的司法含义,以防在实施第20条环保例外条款下的进出口限制措施时违反引言的限制。
