Total Factor Productivity Growth, Technical Change and Technical Efficiency Change in Asian Economies: Decomposition Analysis

The aim of this paper is to analyze total factor productivity (TFP) growth and its components in Asian countries applying Stochastic Frontier Analysis (SFA) to the time series data of 44 Asian countries from 2000 to 2010. Using Battese and Coelli approach, TFP is divided into technical efficiency change and technical change. TFP decomposition using SFA method for the years 1998 to 2007 indicate...

Evolutionary Theories of Cultural Change : An Empirical Perspective

Evolutionary Theories of Cultural Change: An Empirical Perspective Richard R. Nelson Columbia University Version: January18, 2005 Abstract Evolutionary theorizing in the social sciences has a long tradition, going back well before Darwin. Much of contemporary evolutionary theorizing by social scientists about the processes of change at work in various aspects of human culture for example scienc...

Technical change and industrial dynamics as evolutionary processes

Evolutionary Theories

A year before his death, Kurt Lewin taught a graduate course at MIT on theories in social psychology. Stanley Schacter, a student enrolled in the course, described it as “more philosophy of science than a review of different theories. Its purpose was to teach students what a theory is, how to test a theory appropriately, and what makes a theory useful” (Higgins, 2004, p. 138). In this light, Le...

Phytoplankton niches, traits and eco-evolutionary responses to global environmental change

Phytoplankton are major primary producers in aquatic ecosystems and are sensitive to various aspects of global environmental change. They can respond through phenotypic plasticity, species sorting, genetic adaptation, or a combination of these processes. Here we present conceptual, experimental and theoretical ways to predict different phytoplankton responses to global change. Using phytoplankt...
