Economists have long studied the efficiency of firms, industries, and
entire economies. This volume brings together leading scholars to make
connections between efficiency and a number of diverse areas of current
interest to economists, including an examination of the efficiency of
tax systems across generations that overlap, and the efficiency of firm
mergers that highlights the tradeoff between the synergy of the merger
and the problem of managerial oversight in the now larger firm. An
empirical look at productivity growth of states uses a tripartite
decomposition of labor productivity into technological innovation,
improvement in efficiency, and the capital deepening brought about by
new business investment, shedding light on important debates on their
relative importance. The efficiency of patent laws is examined in a
modern model of economic growth. These contributions are complemented by
analyses of methodological problems involved in the measurement,
estimation and aggregation of efficiency indices.
