The aim of this thesis is to propose and illustrate an alternative approach to economic modeling and policy design that is grounded in the innovative field of agent-based computational economics (ACE). The recent crisis pointed out the fundamental role played by macroeconomic policy design in order to preserve social welfare, and the consequent necessity of understanding the effects of coordinated policy measures on the economic system. Classic approaches to macroeconomic modeling, mainly represented by dynamic stochastic general equilibrium models, have been recently criticized for they diffi

This thesis is about the development of agent-based models that are a method of simulation of economic processes and environments using multi-agent systems. Agent-based modeling seems to be an unappreciated approach that is expected and has a potential for a much wider application than it actually has. The purpose of thiswork is to evaluate the reasons for such situation and to offer solutions. The following were identified among the reasons for a low utilization of the method: a wide gap between theory and practice in the field, doubtful reliability of the method, lowconfidence in its results

This thesis consists of three inter-related chapters designed to study the effects of fiscal policy on unemployment, the distribution of income, and social welfare in heterogeneous agent models incorporating unemployment. Each chapter employs a different setup for unemployment in a general equilibrium framework. These include models of equilibrium unemployment, right-to-manage union bargaining, and search and matching. Chapter 1 develops a model with equilibrium unemployment to study the effects of optimal taxation under commitment. Two models are explored: a model with zero economic profits a

This thesis is concentrated broadly in the field of mathematical industrial economics and more specifically upon what is known in the literature as principal-agent relationships. It focuses on investigating the nature of optimal contracts between, say, owners of the firm and the manager appointed by them to run the affairs of the firm or yet again between the owners and the workers employed in the firm. Chapter 1 introduces by first establishing the background of the analysis and then summarising the results of the thesis. The background consists mainly of implicit contract models, both of the

This paper examines the possible contribution of evolutionary economics to macro-economic modelling of flood impacts to provide guidance for future economic risk modelling. Most macro-economic models start from a neoclassical economic perspective and focus on equilibrium outcomes, either in a static or dynamic way, and describe economic processes at a high level of aggregation. As a consequence, they typically fail to account for the complexity of social interactions and other behavioural responses of consumers and producers to disasters, which may affect the macroeconomic impacts of floods.

Economic systems are distributed in the sense that economic agents make decisions without any central control. Prices, quantities, wealth, and market structure emerge from the interaction of agents acting in their own self interest. The concepts and language of systems science are used to define economic systems in a manner that captures and articulates the distributed nature of economic systems. Further, the systems definition permits multiple views of the economic system, and in addition, allows the agents to "step outside" the system in order to study it. Economic systems are defined in suc

In particular, we focus on three main topics: opinion dynamics, herding behavior in financial markets, and language competition. Opinion dynamics models focus on the processes of opinion formation within a society consisting of an ensemble of interacting individuals with diverse opinions. One o

For this purpose, we calibrate a model of fire-sale contagion to the South African banking sector. We use cross-sectional balance sheet data for 29 South African banking institutions.

Our study examines some design alternatives for a carbon market by exploring the fledgling Alberta carbon market.

To achieve this we construct an empirically-calibrated but simple agent-based model, certain aspects of which we selectively modify to incorporate various design options. We make comparisons among these options based on data simulated from the ensuing family of models. We find strong evidence that in general, market design features such as source-of-credits, the scal

The implementation of energy policies oriented to incentive the adoption of efficient lighting technologies in the residential sector requires analytic tools able to describe the market conditions necessary for a successful penetration of the innovations. This article describes, using an agent-based model, the relationship between the micro behaviors of householder\'s adoption of lighting technologies and the aggregated macro patterns of diffusion in the Brazilian residential sector. The model also studies the dynamic between the interaction network parameters and the emerging diffusion charac

Supplying goods to urban areas is a fundamental economic process because the majority of the world population lives and buys goods in cities. Freight distribu-tion activities in urban areas account for roughly 40% of supply chain costs and 60% of supply chain CO2 emissions. Moreover, surging e-commerce trends shape the urban freight transportation arena, increasing its complexity and the pressure on private actors. Thus, urban freight transportation activities generate negative externalities, but are relevant to a great amount of enterprises that compose the economic and social fabric. In thi

Mestrado Gestão de Sistemas de Informação<br>Apesar de a experimentação ser o método mais utilizado em muitas áreas científicas, nem sempre é possível recorrer a esse método nas áreas das Ciências Sociais ou das Ciências Económicas. Uma alternativa é a simulação computacional, em que se recorre a um programa de computador para representar um modelo do fenómeno a estudar, aplicando as abstracções e conceitos considerados relevantes e apropriados, tem-se vindo a tornar um instrumento cada vez mais utilizado e útil na pesquisa científica. Ao longo dos últimos anos, um dos métodos de simulação com

In this dissertation, we attempted to contribute to the discussion about the link between the economic and the social. More specifically, we addressed the debate on the consequences of economically-oriented interaction on social relations. Sociological studies have mostly focused on understanding the opposite direction, i.e., the effect of social relations on economic outcomes. Conversely, our work was motivated by the idea that the consequences of the economic on the social is crucial for social sciences and society in general. First, we reviewed the literature on solidarity and exchange rela

Intensive human-environment interactions are taking place in Midwestern agricultural systems. An integrated modeling framework is suitable for predicting dynamics of key variables of the socio-economic, biophysical, hydrological processes as well as exploring the potential transitions of system states in response to changes of the driving factors. The purpose of this dissertation is to address issues concerning the interacting processes and consequent changes in land use, water balance, and water quality using an integrated modeling framework.

In this thesis, I apply the sophisticated tools made available by the econometrics of panel data and treatment models to a range of different issues. In the first Chapter, an ECM model is used to test on the existence of financing constraints in firms’ investment and R&D, taken a proxy for the efficiency of market institutions and governance rules in different countries. In the second chapter we test an agency model linking pay-performance contracts of CEOS to the financial situation of a firm by using a UK panel data. In the third chapter I use a sophisticated treatment model to evaluate the

Le premier chapitre examine la dynamique de spécialisation des produits verts à travers l'analyse de la complexité économique et des réseaux autocatalytiques. La question principale est de comprendre pourquoi certains pays ne s'engagent pas davantage dans la production de biens verts, pourtant cruciale pour l'atteinte des objectifs de développement durable.

Questa tesi tratta l’estensione di un modello ad agenti per la simulazione e lo studio del mercato elettrico Italiano. Nel modello, gli agenti, che rappresentano le compagnie energetiche presenti nel mercato Italiano, competono tra loro con l’obiettivo di avere il più alto profitto. Ogni agente determina la propria strategia attraverso un algoritmo genetico, che opera su una popolazione di strategie. Questo modello presenta però due limitazioni: (1) agli impianti di produzione di un agente, situati nella stessa zona geografica e aventi in comune la tecnologia di produzione, viene applicata la

O presente estudo busca desenvolver um modelo baseado em agentes para estudar em ambiente simulado baseado em sistemas computacionais as propriedades emergentes decorrentes da aplicação e execução da lei penal. Os modelos baseados em agentes têm-se revelado uma alternativa bastante promissora no estudo de sistemas complexos onde a grande quantidade de variáveis dinâmicas e interagentes tornam impossível o uso de técnicas puramente analíticas para a sua abordagem.
