This chapter discusses a common set of methods that are not currently in wide use in either microeconomics or macroeconomics, but constitute a core of the methodology for models in many different sectors of the economy. The chapter also provides an overview of the varieties of sectoral models,...

This paper describes the recent advances for rapidly and accurately solving matrix Riccati and Sylvester equations and applies them to devise efficient computational methods for solving and estimating dynamic linear economies. The chapter explores the most promising solution methods available...

The WALRAS algorithm calculates competitive equilibria via a distributed tatonnement-like process, in which agents submit single-good demand functions to market-clearing auctions. The algorithm is asynchronous and decentralized with respect to both agents and markets, making it suitable for...

A model of decentralized trade is simulated with firms that produce a given commodity, and consumers who repeatedly wish to purchase one unit of that commodity. Consumers 'shop around,' while firms may attract the attention of potential customers by sending information signals and offering good...
