This book is about the construction of reality. The central aim of this study is to understand how gravity works and how it may be focused and manipulated. While I do not have an answer to this question, the discoveries along the way have been worth collecting into a single volume for future...

The overlapping generations (OLG) model is an important framework for analyzing any type of question in which age cohorts are affected differently by exogenous shocks. However, as the dimensions and degree of heterogeneity in these models increase, the computational burden imposed by rational...

Traditionally, the task of monetary management is usually performed by the monetary authority on behalf of government. However, a key challenge in monetary management is how to deal with uncertainty. Thus, the relevant policy questions must include how best the available instruments of monetary...

By integrating the fiat money into the structural growth model in [1], this paper presents a dynamic model for the simulation study of interest rate. And the model is illustrated with a numerical example. The equilibria of the numerical example are also computed by the method in [2]. The...

This paper analyses the economy-wide and distributional impacts of the increase in electricity tariff in the South African economy. Use is made of CGE-microsimulation to this end. The paper simulates both an actual price increase experienced in the economy and an increase linked to inflation....

This paper measures the distributional and welfare impacts of cutting commodity subsidy and paying cash subsidy. We introduce an extended Input-Output model employing a non-linear programming approach. The model is calibrated based on 2004 Iranian Micro Consistent Matrix with 56 commodity...

The analysis of economywide models is a particularly demanding topic in economics since it involves the study of interdependence. It implies a move to the realm of multiple heterogeneous agents, sectors and institutions interacting in complex ways. While there are some analytical methods and...

DSGE models are the main tool for analysing various questions in problems of monetary, business cycle theory and fiscal policy problems, growth and other fields in international macroeconomics and macroeconomics. Many macroeconomic publications use the DSGE framework. A consensus has been...

This note presents an algorithm for deriving first order conditions applicable to the most common optimisation problems encountered in dynamic stochastic models automatically. Given a symbolic library or a computer algebra system one can efficiently derive first order conditions which can then...
