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...

We establish 16 good practice principles in modelling defined contribution pension plans. These principles cover the following issues: model specification and calibration; modelling quantifiable uncertainty; modelling member choices; modelling member characteristics, such as occupation and...

We consider a pure exchange economy repeated for an indefinite number of periods from a fixed endowment and posit a learning rule which directs convergence to competitive equilibrium. In each period trade converges to an allocation in the contract set, where agents interpret the current (common)...

We present a simple approach to transform a deterministic numerical model, where several agents simultaneously make decisions, into a stochastic model. This approach, which builds on scenario aggregation, a numerical method developed to solve decision problems under uncertainty, is used to build...

Computational methods both open the frontiers of economic analysis and serve as a bottleneck in what can be achieved. Using the quantum Monte Carlo (QMC) algorithm, we are the first to study whether quantum computing can improve the run time of economic applications and challenges in doing so....

This paper assesses the economic implications of the United Kingdom leaving the European Union. The basic data on trade in goods and services and investment between the two parties suggest that cost of ‘Brexit’ could be substantial. Trade between the UK and the EU27 is large and of a similar...

To help first- or second-year graduate students in economics apply their theoretical training, this paper shows how to solve a simple and intuitive computable general equilibrium (CGE) model using a calculator. Because this simplified Harberger model uses Cobb Douglas functional forms for...

Throughout our history we have demonstrated the relationship between the decisions of energetic character, economy and the environment. For this reason is that they begin to develop and implement energetic modeling techniques as alternative tools for both the development of energy policies, and...

How wrong could policymakers be when using linearized solutions to their macroeconomic models instead of nonlinear global solutions? This question became of much practical interest during the Great Recession and the recent zero lower bound crisis. We assess the importance of nonlinearities in a...
