A large literature documents a substantial rise in U.S. wage inequality and educational wage differentials during the 1980s and early 1990s and concludes that these wage structure changes can be accounted for by shifts in the supply of and demand for skills reinforced by the erosion of labor market institutions supporting low- and middlewage workers. Drawing on an additional decade of data, several “revisionist ” studies reject this consensus to conclude that (1) the rise in wage inequality was an “episodic ” event of the first-half of the 1980s, (2) this rise was mainly caused by a falling minimum wage, and (3) increased residual wage inequality since the mid-1980s reflects the confounding effects of labor force composition. We reexamine these claims using data from the Current Population Survey for 1963 to 2005 and find only limited support. A slowing of the growth of overall wage inequality in the 1990s hides a divergence in the paths of upper-tail (90/50) and lower-tail (50/10) inequality. Uppertail wage inequality has been increasing steadily since 1980 even after adjusting for labor force composition changes. Lower-tail wage inequality increased sharply in the first-half of the 1980s but has flattened or narrowed since the late 1980s. Strong time series correlations of the real minimum wage and upper-tail wage inequality raise questions concerning the causal interpretation of relationships between the minimum wage and both overall and

This report, commissioned by the Treasury, reviews the international and New Zealand evidence on trends in the distribution of earnings over the past 20 years. It assesses the international evidence on the strength of the various explanations for changes in the earnings distribution. It concludes with suggestions on how the trends in the earnings distribution in New Zealand might be further analysed. Considerable variation has occurred in trends in the distribution of earnings between industrialised economies, with English speaking countries showing the greatest increases in earnings inequalities, and European countries showing the least. The New Zealand evidence also shows a growth in earnings inequality, and indicates that this has been due to both growth in inequality in wage rates and in weekly hours of work. Trends in earnings inequalities together with changes in the distribution of employment appear to explain much of the movement in income inequality in New Zealand. The international literature has attributed changes in the distribution of earnings to labour supply side factors (eg, education, age, gender), demand side factors (eg, technological change, international trade), and institutional factors (eg, union effects, labour market regulation).

desarrollo productivo From industrial economics to digital economics: an introduction to the transition

ABSTRACT: The world has embraced a set of concepts (knowledge driven growth) which are seen as the ‘core of future growth and wellbeing ’ without any commonly agreed notion of what they are, how they might be measured, and crucially therefore, how they actually do (or might) affect economic growth and social wellbeing. The theory of how the mechanism works lacks important detail.

This paper critically examines the trade and technology theories which dominate the large and growing literature on the determinants of changes in income inequality in advanced industrial countries during the 1980s and 1990s. Both theories, despite their rather different approaches to the subject are shown to have a common premise: advanced countries have experienced a fall in the relative demand for unskilled labour and an increase in that of skilled labour. This single explanation for both phenomena has been dubbed the 'transatlantic consensus'. This paper argues that this consensus, together with the associated theories based on trade with the Third World and skill biased technological progress respectively, is analytically as well as empirically unsatisfactory. It puts forward an alternative analysis which emphasises the role of institutions (e.g. unions, minimum wages), macro-economic conditions and social norms. It naturally arrives at rather different policy conclusions from those of the orthodox economists.

The resurgence of the American economy since 1995 has outrun all but the most optimistic expectations. Economic forecasting models have been seriously off track and growth projections have been revised to reflect a more sanguine outlook only recently1. It is not surprising that the unusual combination of more rapid growth and slower inflation in the 1990's has touched off a strenuous debate among economists about whether improvements in America's economic performance can be sustained. The starting point for the economic debate is the thesis that the 1990's are a mirror image of the 1970's, when an unfavorable series of "supply shocks" led to stagflation-- slower growth and higher inflation2. In this view, the development of information technology (IT) is one of a series of positive, but temporary, shocks. The competing perspective is that IT has produced a fundamental change in the U.S. economy, leading to a permanent improvement in growth prospects3. The relentless decline in the prices of information technology equipment
