Consider the following two opinions, both of which can be found in the literature of consumer demand systems: (a) As the real income of a consumer becomes indefinitely large, re-mixing the consumption bundle becomes irrelevant: having chosen the ultimately satisfying budget shares at any given...

This is a companion paper to Impact Preliminary Working Paper No OP-73 in which Rimmer and Powell report on a new implicitly directly additive demand system (AIDADS) which (in Cooper and McLaren's 1992b terminology) is effectively globally regular. In OP-73 AIDADS is fitted to a six-commodity...

The main purpose of this study is to provide some microeconomic tools for the calibration of a computable general equilibrium (CGE) model for Iran. For decades, CGE models have increasingly been used to study the economic and social consequences of government policy schemes and the distribution...

We develop a methodology for incorporating nutrition impacts in economy-wide analyses, providing entry points for where, when and how to act. It accounts for three channels of consumption, directly via primary commodities and indirectly via processed foods and food-related services, and produces...

We examine linkages between aggregate household income, distribution of that income, and aggregate cross-country expenditure patterns. We are able to decompose income effects into international income dispersion effects (from variations in average income) and national income dispersion (income...

This paper focuses on the causes of increased wage inequality in OECD countries in recent years and its decomposition into the component factors of trade surges in low wage products and technological change that has preoccupied the trade and wages literature. It argues that the length of...

The paper presents a new method to solve DSGE models with a great number of heterogeneous agents. Using tools from systems and control theory, it is shown how to reduce the dimension of the state and the policy vector so that the reduced model approximates the original model with high precision....

The aim of this paper seeks to introduce the basis of the energy economics models defined as a market equilibrium problems-mixed complementarily problem (MCP). This technique allows the integration of bottom-up programming models of the energy system into top-down general computable equilibrium...

The study of the impact of public investment on poverty is currently of particular importance due to, among other factors, the commitments that several countries have acquired in the framework of the Millennium Development Goals and the current political situation which gives a more prominent...
