We present a new approach to the approximation of equilibrium solutions to nonlinear rational expectations models that applies to any order of approximation. The approach relies on a particular version of Taylor series approximations - the differential version - and on a scalar perturbation of...

This paper develops a novel approach for estimating latent state variables of Dynamic Stochastic General Equilibrium (DSGE) models that are solved using a second-order accurate approximation. I apply the Kalman filter to a state-space representation of the second-order solution based on the...

To estimate the emissions reductions and costs of a climate policy, analysts usually compare a policy scenario with a baseline scenario of future economic conditions without the policy. Both scenarios require assumptions about the future course of numerous factors such as population growth,...

We explore how and by how much the values of elasticities of substitution affect estimates of the cost of emissions reduction policies in computable general equilibrium (CGE) models. We use G-Cubed, an intertemporal CGE model, to carry out a sensitivity and factor decomposition analysis. Average...

The prediction of future temperature increases depends critically on the projections of future greenhouse gas emissions. Yet there is a vigorous debate about how these projections should be undertaken and how reasonable is the approach of the Special Report on Emissions Scenarios (SRES)...

International pressure to revalue China’s currency stems in part from the expectation that rapid economic growth should be associated with a real exchange rate appreciation. This hinges on the Balassa-Samuelson hypothesis under which economic growth, stemming from improvements in traded sector...

With exports almost half of its GDP and most of these directed to Europe and North America, negative financial shocks in those regions might be expected to retard China’s growth. Yet mitigating factors include the temporary flight of North American and European savings into Chinese investment...

The retreat from public ownership of service firms and industries has left behind numerous private monopolies and oligopolies supervised by regulatory agencies. Services industries in government and private ownership generate two-thirds of Australia’s value added and employ three quarters of...

The notion of "convergence" of economic variables across countries is a useful concept and in the case of income per capita, a well studied area. If there is empirical evidence of convergence of some economic variables across countries, then our ability to prdict the future (or at least...

The world's two population giants have undergone significant, and significantly different, demographic transitions since the 1950s. The demographic dividends associated with these transitions during the first three decades of this century are examined using a global economic model that...
