Projected demographic changes in industrialized and developing countries vary in extent and timing but will reduce the share of the population in working age everywhere. Conventional wisdom suggests that this will increase capital intensity with falling rates of return to capital and increasing...

First, we propose a more efficient implementation of the Smolyak method for interpolation, namely, we show how to avoid costly evaluations of repeated basis functions in the conventional Smolyak formula. Second, we extend the Smolyak method to include anisotropic constructions; this allows us to...

This paper explores the potential impacts on both China and other major countries of possible mega trade deals. These include the Trans-Pacific Partnership (TPP), the Regional Comprehensive Economic Partnership (RCEP), and various blocked deals. We use a numerical 13-country global general...

The Trans-Pacific Partnership (TPP) is a new negotiation on cross border liberalization of goods and service flows going beyond WTO disciplines and focused on issues such as regulation and border controls. Though the US, Australia and other pacific countries are included, China is notable for...

We study a class of infinite-horizon nonlinear dynamic economic models in which preferences, technology and laws of motion for exogenous variables can change over time either deterministically or stochastically, according to a Markov process with time-varying transition probabilities, or both....

We describe a sparse grid collocation algorithm to compute recursive solutions of dynamic economies with a sizable number of state variables. We show how powerful this method may be in applications by computing the nonlinear recursive solution of an international real business cycle model with a...

Seminal work by Weitzman (1974) revealed prices are preferred to quantities when marginal benefits are relatively flat compared to marginal costs. We extend this comparison to indexed policies, where quantities are proportional to an index, such as output. We find that policy preferences hinge...

Numerical simulation analysis of bargaining solutions is little developed in existing literature. Here we use a multi country, single period numerical general equilibrium model which captures China and her major trading partners and examine the outcomes of trade policy bargaining solutions...

This paper uses a new large-scale dynamic simulation model to compare the equity, efficiency, and macroeconomic effects of five alternative to the current U.S. federal income tax. These reforms are a proportional income tax, a proportional consumption tax, a flat tax, a flat tax with transition...

Demographic change has differential impacts on the welfare of current and future generations. In a simple closed economy, aging -- a relative scarcity of young workers -- increases wages, increasing the welfare of the young. At the same time, population aging will reduce rates of return to...
