An important problem in the political economy of the United Kingdom is that the disparity of unemployment rates across its regions is much more marked than the corresponding dispersion of wage rates. One possibility is that this is due to the attitude of trade unions to their members in different regions. If unions wish to preserve parity between members in different regions, then they will value wage equality between regions over and above wage levels. This may then persuade them to overlook interregional productivity differences in setting wages. The price that low-efficiency regions will then pay for this desire for wage equality is higher unemployment rates. Copyright 1991 by Kluwer Academic Publishers
