Product market reforms, labour market institutions and unemployment
We analyze the impact of product market competition on unemployment and wages, and how
this depends on labour market institutions. We use differential changes in regulations across
OECD countries over the 1980s and 1990s to identify the effects of competition. We find that
increased product market competition reduces unemployment, and that it does so more in
countries with labour market institutions that increase worker bargaining power. The theoretical
intuition is that both firms with market power and unions with bargaining power are constrained
in their behaviour by the elasticity of demand in the product market. We also find that the effect
of increased competition on real wages is beneficial to workers, but less so when they have high
bargaining power. Intuitively, real wages increase through a drop in the general price level, but
workers with bargaining power lose out somewhat from a reduction in the rents that they had
previously captured
On wild ramification in quaternion extensions
Quaternion extensions are often the smallest extensions to exhibit special
properties. In the setting of the Hasse-Arf Theorem, for instance, quaternion
extensions are used to illustrate the fact that upper ramification numbers need
not be integers. These extensions play a similar role in Galois module
structure. To better understand these examples, we catalog the ramification
filtrations that are possible in totally ramified extensions of dyadic number
fields. Interestingly, we find that the catalog depends, for sharp lower
bounds, upon the refined ramification filtration, which is associated with the
biquatratic subfield. Moreover these examples, as counter-examples to the
conclusion of Hasse-Arf, occur only when the refined filtration is, in two
different ways, extreme.Comment: 19 pages. This is an extensive revision of the earlier draf
Circular 55
This report summarizes evaluations of vegetable varieties conducted by the Horticultural Research Program
of the University of Alaska-Fairbanks. The objective of this research is to select varieties of vegetables
that are adapted to the environment of interior Alaska. Vegetable crops whose adaptability may be improved
through development of improved cultural techniques are also identified. The selection effort is
directed at finding varieties useful to both commercial growers and home gardeners. Varieties are chosen
for inclusion in the variety tests on the basis of their description, the latitude of origin, and the record
of the plant-breeding programs for producing kinds that have previously been found adapted. Standard recommended
varieties are included in the trials for comparison.Introduction -- Weather Summary, 1985 -- Table 1.
