In this paper we argue that in realistically calibrated two period general equilibrium models with incomplete markets CAPM-pricing provides a good benchmark for equilibrium prices even when agents are not mean-variance optimizers and returns are not normally distributed. We numerically approximate equilibria for a variety of di erent speci cations for preferences, endowments and dividends and c...

Agriculture is the focus of much contention in free trade negotiations. The Japanese government is against liberalizing the rice trade on the grounds that it would threaten “national food security” in the events of such shocks as crop failure, war, and embargo. Trade liberalization is expected to make Japan more dependent upon food imports and to make the Japanese economy more susceptible to th...

Aim/purpose – This study sought to assess the impact of an increased historical fixed VAT rate 14% current 15% on South African economy. Design/methodology/approach The method applied in this was based a Dynamic Computable General Equilibrium (CGE) model evaluate both and new CGE has been proven over years be suitable when evaluating assessment any shock within Enhancements were made by researc...

This paper analyses a RBC model in continuous time featuring deterministic incremental development of technology and stochastic fundamental inventions arriving according to a Poisson process. Other than in standard RBC models, shocks are uncorrelated, irregular and rather seldom. In two special cases analytical solutions are presented. In the general case a delay differential equation (DDE) has...

A solution methodology employing finite elements and a parameterized expectations algorithm is proposed for computing the equilibrium of a CIA model economy. The stochastic growth model considered introduces money via a CIA constraint, and takes consumption as the cash good and leisure and capital investment as credit goods. The ability of the methodology to approximate the solution of the mode...

Should Old-Age Benefits Be Earnings-Tested? We study the welfare effects of earnings testing flat-rate old-age benefits in a quantitative overlapping generations model with idiosyncratic labor income risk. In our model economy, even a moderate earnings testing reduces individuals’ expected lifetime utility, whenever other taxes are taken into account. Moreover, it also lowers the realized lifet...

This paper explores, through the use of a sequence of computable general equilibrium models, what harm or good, as measured both in terms of real output and utility, might be accomplished through coordinated perturbations in excise and income tax policy among sovereign jurisdictions. We focus on two issues: the taxation of below-retail transactions and the taxation of E-commerce across state li...

using the quarterly data of 1990:1 to 2008:1 and in a general equilibrium approach, we investigate the long run equilibrium path of the equilibrium interest rate as well as the potential output. we implement a structural reduced form of a general equilibrium model consistent with iran’s economy and estimate the unobservable variables by employing the kalman filtering technique. a exponential ut...

In this paper an applied general equilibrium model for the Extremadura region is presented. Our aim is to show the importance of agricultural subsidies in this economy, that it is a distinctive characteristic of this region. To achieve this purpose, we analyse the effects of a supression of these subsidies, using different scenaries related to the labour market and tax compensation. Model param...
