Book Description
This dissertation consists of three essays about heterogeneous agents in the dynamic economy and how to deal with the asymmetric information arose by heterogeneity. Firstly, I consider the optimal taxation issue in a dynamic endogenous growth model with considering human capital accumulation, and agents ability is heterogeneous and private information. Moreover, the agents with higher ability have positive external effects on others. By using the two-sector endogenous model, I show that it is optimal to impose different income and capital income taxes on people with different abilities. Specifically, positive marginal income tax is adopted for people with lower ability while no tax is imposed for people with higher ability; marginal capital income tax is zero whatever the agent's is low or high. As for people using the capital and labor for human capital accumulation, the government should subsidize them whatever their ability is. Secondly, I study the optimal monetary and fiscal policy with heterogeneous agents based on the search-theoretical environment where money is essential and consider the private information. I first solve the households' problem in the centralized and decentralized market, and find out the optimal conditions. Then, in this section, I describe the problem that social planner faces by involving uncertainty and agents whose types are continuous. By comparing the optimal conditions in this generous setting, I show that the Friedman rule is no longer optimal when jointed with nonlinear taxation of income. Moreover, the capital income taxation is not zero. Moreover, I constructs a general theoretical model to consider two kinds of financial frictions in the economy with financial intermediaries. By quantitative analysis the model with three separate shocks which are a negative collateral shock, a negative productivity shock and a positive shock to bankers' divert rate, I find that a negative collateral shock which tightens firms' financing constraints on investment can generate an equity price boom which is different from what is observed in recessions. Therefore, the collateral shock is not the main reason for the business cycle, while the negative productivity shock and bankers' moral hazard problem are more important aspects to explain current economy.

Book Description
Economic application of nonlinear dynamics, microscopic agent-based modelling, and the use of artificial intelligence techniques as learning devices of boundedly rational actors are among the most exciting interdisciplinary ventures of economic theory over the past decade. This volume provides us with a most fascinating series of examples on "complexity in action" exemplifying the scope and explanatory power of these innovative approaches.

Book Description
Handbook of Computational Economics: Heterogeneous Agent Modeling, Volume Four, focuses on heterogeneous agent models, emphasizing recent advances in macroeconomics (including DSGE), finance, empirical validation and experiments, networks and related applications. Capturing the advances made since the publication of Volume Two (Tesfatsion & Judd, 2006), it provides high-level literature with sections devoted to Macroeconomics, Finance, Empirical Validation and Experiments, Networks, and other applications, including Innovation Diffusion in Heterogeneous Populations, Market Design and Electricity Markets, and a final section on Perspectives on Heterogeneity. Helps readers fully understand the dynamic properties of realistically rendered economic systems Emphasizes detailed specifications of structural conditions, institutional arrangements and behavioral dispositions Provides broad assessments that can lead researchers to recognize new synergies and opportunities

Book Description
This paper examines the consequences of (S, s) pricing rules in a dynamic economy with heterogeneous costs of price adjustment. We construct the stationary distributions for aggregate output and prices for our model economy. As a result of our assumption of heterogeneous costs we find that: (i) Some sectors change prices more regularly than others; (ii) Price changes are asynchronized (relative prices may be moving in opposite directions in different sectors); (iii) The economy may be more sensitive to demand shocks. There is broad empirical support for the predictions of the model.

Book Description
This book offers a practical guide to Agent Based economic modeling, adopting a “learning by doing” approach to help the reader master the fundamental tools needed to create and analyze Agent Based models. After providing them with a basic “toolkit” for Agent Based modeling, it present and discusses didactic models of real financial and economic systems in detail. While stressing the main features and advantages of the bottom-up perspective inherent to this approach, the book also highlights the logic and practical steps that characterize the model building procedure. A detailed description of the underlying codes, developed using R and C, is also provided. In addition, each didactic model is accompanied by exercises and applications designed to promote active learning on the part of the reader. Following the same approach, the book also presents several complementary tools required for the analysis and validation of the models, such as sensitivity experiments, calibration exercises, economic network and statistical distributions analysis. By the end of the book, the reader will have gained a deeper understanding of the Agent Based methodology and be prepared to use the fundamental techniques required to start developing their own economic models. Accordingly, “Economics with Heterogeneous Interacting Agents” will be of particular interest to graduate and postgraduate students, as well as to academic institutions and lecturers interested in including an overview of the AB approach to economic modeling in their courses.

Book Description
Modern business cycle theory and growth theory uses stochastic dynamic general equilibrium models. Many mathematical tools are needed to solve these models. The book presents various methods for computing the dynamics of general equilibrium models. In part I, the representative-agent stochastic growth model is solved with the help of value function iteration, linear and linear quadratic approximation methods, parameterised expectations and projection methods. In order to apply these methods, fundamentals from numerical analysis are reviewed in detail. Part II discusses methods for solving heterogeneous-agent economies. In such economies, the distribution of the individual state variables is endogenous. This part of the book also serves as an introduction to the modern theory of distribution economics. Applications include the dynamics of the income distribution over the business cycle or the overlapping-generations model. Through an accompanying home page to this book, computer codes to all applications can be downloaded.

Book Description
This volume is centered around the issue of market design and resulting market dynamics. The economic crisis of 2007-2009 has once again highlighted the importance of a proper design of market protocols and institutional details for economic dynamics and macroeconomics. Papers in this volume capture institutional details of particular markets, behavioral details of agents' decision making as well as spillovers between markets and effects to the macroeconomy. Computational methods are used to replicate and understand market dynamics emerging from interaction of heterogeneous agents, and to develop models that have predictive power for complex market dynamics. Finally treatments of overlapping generations models and differential games with heterogeneous actors are provided.
