We propose a novel approach to the statistical analysis of simulation models and, especially, agent-based models (ABMs). Our main goal is to provide a fully automated and model-independent tool-kit to inspect simulations and perform counter-factual analysis. Our approach: (i) is easy-to-use by...

Taking agent-based models (ABM) closer to the data is an open challenge. This paper explicitly tackles parameter space exploration and calibration of ABMs combining supervised machine-learning and intelligent sampling to build a surrogate meta-model. The proposed approach provides a fast and...

Simulated models suffer intrinsically from validation and comparison problems. The choice of a suitable indicator quantifying the distance between the model and the data is pivotal to model selection. However, how to validate and discriminate between alternative models is still an open problem...

The global food price shock of 2006-2008 has particularly affected poorer strata of populations in several developing countries. In Egypt and some other countries it has put food subsidy schemes to the test. This paper develops two comparable computable general equilibrium models for Egypt and...

This paper presents a model of a developing economy with three sectors - a modern sector producing manufactures and services, a traditional sector producing agricultural goods, and a third sector providing energy. Modern and energy sector are assumed to be demand-constrained; the agricultural...

This paper investigates the impact on the network growth of the level of merchant discount, the level of Multilateral Interchange Fee (MIF), and the consumers' and the merchants' awareness of positive network effects. In an artificial market, in which issuers and acquirers belong to the same...

The great financial turmoil that started 2007 has brought bank regulation back into the political debate. There is talk about imposing new regulations on banks and other financial intermediaries. Yet, we are not convinced that it is completely understood how the existing regulation affects...
