The sources of aggregate productivity growth are explored using detailed data for four-digit U.S. manufacturing industries during 1958-96 and a decomposition formula which allows to quantify the contribution of structural change. Labor productivity as well as total factor productivity are considered and the aggregation is performed with either value-added or employment shares. It is shown that ...

An aggregate game is a normal-form game with the property that each player’s payoff is a function only of his own strategy and an aggregate function of the strategy profile of all players. Aggregate games possess a set of purely algebraic properties that can often provide simple characterizations of equilibrium aggregates without first requiring that one solves for the equilibrium strategy prof...

The Aggregate Demand – Aggregate Supply framework has dominated intermediate macroeconomics textbooks since the 1980s. However, there have been 2007). In spite of these criticisms, the ADAS framework had continued to dominate the textbooks, with little or no response to these criticisms. This paper reviews the main criticisms of the ADAS framework, and then focuses on Gregory Mankiw's presentat...

In this study, a novel approach to modeling the ultrasonic softening effect during metal plasticity is developed, where slip systems experience differential depending on their orientation relative direction. The directional model was implemented within Visco-Plastic Self-Consistent (VPSC) model, material and parameters are calibrated based micro-tensile test data of pure copper with tension alo...

the purpose of this research was to evaluate the application of recycled aggregates of constructiondebris such as concrete, cement block and rubbles from pars-kangan site in asphalt concrete mix design. toevaluate the performance of aggregates different mix designs with recycled aggregate percentages of 0, 10,30, 50 and bitumen percentages of 4, 4.5, 5, 5.5, 6, and 6.5 were provided and two mar...
