Beckman, Jayson; Hertel, Thomas; Tyner, Wallace - In: Energy Economics 33 (2011) 5, pp. 799-806

Although CGE models have received heavy usage -- particularly in the analysis of broad-based policies relating to energy, climate and trade, they are often criticized as being insufficiently validated. Key parameters are often not econometrically estimated, and the performance of the model as a...

From SHIW to IT-SILC: Construction and Representativeness of the New CAPP_DYN First-Year Population

Ciani, Emanuele; fresu, Donatella - Dipartimento di Economia "Marco Biagi", Università … - 2011

This paper describes the construction of the initial population in CAPP_DYN and illustrates the degree of representativeness of the Italian population in 2006. While the previous version of the model was constructed using the Bank of Italy Survey on Household Income and Wealth, the current...

Simulating heterogeneous multinational firms

Arita, Shawn; Tanaka, Kiyoyasu - Institute of Developing Economies, Japan External Trade … - 2011

This paper develops a micro-simulation framework for multinational entry and sales activities across countries. The model is based on Eaton, Kortum, and Kramarz's (2010) quantitative trade model adapted towards multinational production. Using micro data on Japanese manufacturing firms, we first...

Business cycle measurement with some theory

Canova, Fabio; Paustian, Matthias - C.E.P.R. Discussion Papers - 2011

A method to evaluate cyclical models which does not require knowledge of the DGP and the exact specification of the aggregate decision rules is proposed. We derive robust restrictions in a class of models; use some to identify structural shocks in the data and others to evaluate the class or...

Computer simulation of a biomass gasification-solid oxide fuel cell power system using Aspen Plus

Doherty, Wayne; Reynolds, Anthony; Kennedy, David - In: Energy 35 (2010) 12, pp. 4545-4555

The operation and performance of a SOFC (solid oxide fuel cell) stack on biomass syn-gas from a biomass gasification CHP (combined heat and power) plant is investigated. The objective of this work is to develop a model of a biomass-SOFC system capable of predicting performance under diverse...

A microscopic pedestrian-simulation model and its application to intersecting flows

Guo, Ren-Yong; Wong, S.C.; Huang, Hai-Jun; Zhang, Peng; … - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 3, pp. 515-526

We develop a microscopic pedestrian-simulation model in which pedestrian positions are updated at discrete time steps. At each time step, each pedestrian probabilistically selects a direction of movement from a predetermined set according to a logit-type function that considers the dynamics of...

Measurement with Some Theory: a New Approach to Evaluate Business Cycle Models (with appendices)

Canova, Fabio; Paustian, Matthias - Barcelona Graduate School of Economics (Barcelona GSE) - 2010

We propose a method to evaluate cyclical models which does not require knowledge of the DGP and the exact specification of the aggregate decision rules. We derive robust restrictions in a class of models; use some to identify structural shocks in the data and others to evaluate the class or...

Bayesian inference method for model validation and confidence extrapolation

Jiang, Xiaomo; Mahadevan, Sankaran - In: Journal of Applied Statistics 36 (2009) 6, pp. 659-677

This paper presents a Bayesian-hypothesis-testing-based methodology for model validation and confidence extrapolation … the confidence in the model validation decision is investigated. The probabilities of Type I and Type II errors in … decision-making during the model validation and confidence extrapolation are quantified. The proposed methodologies are applied …
