The unionized share of the work force changed markedly in the United Kingdom between the 1970s and 1980s. In the 1970s density rose steadily, making the United Kingdom the most heavily organized large OECD country. In the 1980s, by contrast, density fell by 1.4 percentage points per annum -- a...

H. Gregg Lewis' estimates of the relative wage effect of unionism between 1920 and 1958 are routinely cited though they have rarely been subject to scrutiny. This paper extends Lewis' data to 1980 and, in particular, we construct a series on union membership that links up with the data available...

Using a unique longitudinal representative survey of both manufacturing and non-manufacturing businesses in the United States during the 1990's, I examine the incidence and intensity of organizational innovation and the factors associated with investments in organizational innovation. Past...

What type of businesses do unions target for organizing? A dynamic model of the union organizing process is constructed to answer this question. A union monitors establishments in an industry to learn about their productivity, and decides which ones to organize and when. An establishment becomes...

We use a demand/supply framework to analyze 1) the decline in union membership since 1977 in the United States and 2) the difference in unionization rates between the United States and Canada. We extend earlier work on these problems by analyzing new data for 1991 from the General Social Survey...

The dramatic decline in unionization over the last decade is investigated in the context of a supply/demand model of union status determination. Data from surveys conducted in 1977 and 1984 are used to decompose the decline into components due to a drop in the demand for union representation and...

This paper uses broadly comparable micro data at the level of the individual to examine the extent to which union relative wage effects vary across groups and through time. The main findings may be summarized as follows. a) The union wage gap averages 15% in the US and 10% in Great Britain. b)...

This study presents new estimates of collective bargaining coverage and union membership for detailed U.S. industries. It compares the new coverage and membership figures with each other and with figures derived by researchers for the early 1960's and analyzes the divergences. This analysis...

During the past two decades, union density has declined in the United States and employer provision of health benefits has undergone substantial changes in extent and form. Using individual data spanning the years 1983-1997, combined with establishment data for 1993, we update and extend...

Recent estimates in standard models of wage determination for both unionization and occupational licensing have shown wage effects that are similar across the two institutions. These cross-sectional estimates use specialized data sets, with small sample sizes, for the period 2006 through 2008....
