EXPLAINING RISING INEQUALITY: SKILL‐BIASED TECHNICAL CHANGE AND NORTH–SOUTH TRADE*

Abstract We review the ‘skill‐biased technological change (SBTC) versus North–South trade (NST)’ debate in order to explain widening wage inequality between skilled and unskilled workers. The traditional explanations based on exogenous SBTC and on the North–South Heckscher–Ohlin–Samuelson approach, as well as the early estimates that diagnosed a clear prevalence of the former, are firstly exposed and discussed. A presentation is then made of the recent theoretical literature that endogenizes SBTC, introduces new channels of impacts from NST, and combines both explanations. Finally, the current estimates show that (i) both explanations are relevant, (ii) their impacts differ according to industries and countries, (iii) outsourcing is the main vector of impact from NST and (iv) SBTC and NST interact.     

A STUDY OF ORGANIZATIONAL 'FRAMEWORK' AND 'PROCESS' MODALITIES FOR THE IMPLEMENTATION OF BUSINESS-LEVEL STRATEGIC DECISIONS*

Organization framework and process are proposed as two modalities for implementing intended business-level strategic decisions. A model is developed in which the components of these two modalities are defined and related to the implementation of low cost and differentiation strategic decisions. The implementation of 57 decisions in integrated circuits, petroleum, and health care firms are used to test the research hypotheses. The findings suggest that implementation in these firms utilized both framework and process structural elements, but that a different implementation gestalt characterized each type of strategic decision. Implications for strategy implementation are discussed.
