Hercules : a modeling system with knowledge about economics (Английский)

The paper is concerned with the effectiveness of economic modeling. It argues that the key problems of economic modeling are the time and effort it takes to implement a model, the problems of detecting...

HERCULES : a system for development of multisectoral economywide models (Английский)

This paper reports on a new system called Hercules (High Level Economic Representation for the Construction and Use of Large Economy wide Systems), for developing multisectoral models. Hercules permits...

An approach to macroeconomic model building based on social accounting principles (Английский)

The paper sets out, using the example of a small comparative static model of Thailand for 1980, an approach to macro-economic model building which is based on having two versions of a social accounting...

Modeling systems and nonlinear programming in a research environment (Английский)

Nonlinear programming (NLP) algorithms are often designed for expert users and users from other fields can find them hard to work with. The paper argues that high level modeling systems can help researchers...

The transaction values approach to the formulation and implementation of economywide equilibrium models (Английский)

The paper presents a new approach for the formulation and implementation of economywide models. The approach uses extensively Social Accounting Matrices (SAM). It starts with the observation that each...

CONOPT : a GRG - code for large sparse dynamic nonlinear optimization problems (Английский)

The paper presents CONOPT, an optimization system for static and dynamic large scale nonlinearly constrained optimization problems. The system is based on the GRG algorithm. All computations involving...

The transaction value approach : a systematic method of defining economywide models based on social accounting matrices (Английский)

Macroeconomic adjustment in Thailand : demand management and supply conditions (Английский)

This 1983 article, Macroeconomic Adjustment in Thailand: Demand Management and Supply Conditions, was reprinted with permission from the Journal of Policy Modeling. Within the framework of a fix-price...

Thailand - An analysis of structural and non-structural adjustments (Английский)

Within the framework of a four-sector macroeconomic model, comparative statics are used to assess alternative ways of macroeconomic adjustments in the Thai economy. Fiscal policy interventions, manipulations...

Combining an optimal control program with the time series processor system (Английский)

The time series processor (TSP) system developed at various universities in the United States is used by many universities and government offices to perform data manipulation, estimate econometric models...

Detecting or verifying sparsity structure in large scale nonlinear programming (Английский)

This paper describes some algorithms for the following problem : given a nonlinear function defined as a black box, find which variables the function actually depends on (the set of active variables) and...
