Markov bargaining games
I consider an alternating offer bargaining game which is played by a risk neutral buyer and seller, where the value of the good to be traded follows a Markov process. For these games the existence of a perfect equilibrium is proved and the set of equilibrium payoffs and strategies are characterised. The main results are (a) if the buyer is less patient than the seller, then there will be delays in the players reaching an agreement, the buyer is forced into a suboptimal consumption policy and the equilibrium is ex-ante inefficient, and (b) if the buyer is more patient than the seller, then there is a unique and efficient equilibrium where agreement is immediate
Occurrence and distribution of barite in the permo-triassic siksikpuk formation along the Brooks Range haul road
Barite commonly occurs in Permian to Triassic age rocks along the north flank of the Brooks Range. The Siksikpuk Formation (Wolfcampian to lowest Guadalupian age) is noted for its barite and is well exposed in the vicinity of Galbraith Lake along the pipeline haul road (Figure 1). The proximity of these barite deposits to an existing road made them a logical selection for investigation. The study was designed to provide detailed stratigraphic information on barite quantity and quality, associated clay mineralogy, and relationship of barite to environments of deposition.Introduction -- Geologic setting -- Atigun Gorge section -- Barite -- Occurrence -- Origin -- Quantity -- Conclusion -- References
Bargaining and the timing of investment
The joint determination of the timing of investment and wage bargaining is modelled. Two cases are considered: (a) There is an alternating-offer bargaining game over binding wage contracts and production is possible only when agreement is reached. (b) There are no binding contracts so revenue is divided in period-by-period bargaining post-investment. Investment can occur earlier in case (b) than in case (a) and the equilibrium in case (b) can Pareto-dominate the equilibrium with binding contracts. These conclusions depend on players' discount factors
On the Non-Lorentz Invariance of M.W. Evans O(3)-Symmetry Law
Correcting a former proof of M.W. Evans it is shown that his O(3) hypothesis
is not Lorentz invariant and hence no law of Physics.Comment: 5 page

The calibration of a semi-quantitative approach to fish stock assessment in the North West Region of the NRA
(1) A total of 45 sites was sampled, each being fished using
the semi-quantitative and quantitative techniques.
(2) A significant relationship existed between the
semi-quantitative and Quantitative results for all age
groups of salmonids (R2 83.4% to 96.1%, p < 0.0001).
(3) The results from each site were categorised according to
an existing classification system for quantitative and
semi-quantitative data. The semi-quantitative component of
this system was modified using the results of this
investigation. The degree of error associated with sites
classified semi-quantitatively was found to be slightly
less when using the modified system for 0+ salmon, > 0+
salmon and 0+ trout, ranging from 10.5% to 30%.
(4) Insufficient data points were available for the analysis
of coarse fish data
Optimal complementary auctions
This paper considers the situation where two products are sold by the same seller, but to disjoint sets of potential buyers. Externalities may arise from each market outcome to the other. The paper examines the nature of the seller's optimal mechanism, and, for example in the case of positive externalities, it is shown that the allocation decision in either market depends on the highest types in both markets. The optimal mechanism can be implemented by an indirect mechanism that essentially charges winning bidders for the value of their externalities. The analysis is applied to the sale of public sector franchises including exploration and development rights for oil and gas tracts
The River Lune strategic stock assessment survey 1991 with particular reference to salmonids
In the past stock assessment surveys were generally
reactive in response to a particular problem e.g. a
pollution incident and as such were limited in the
information they provided. A programme of strategic stock
assessment would be more beneficial, providing up to date
information on the status and composition of the stock.
On a national level this could reveal trends in
population dynamics and enable comparisons to be made
between key rivers and between regions.
The Stock Assessment Task Group (1991) has recommended
annual strategic surveys for juvenile salmonids and
triennial strategic surveys for coarse fish and non-
migratory salmonids.
The aim of this pilot study was to gain information on
species distribution and their relative abundance within
the River Lune catchment, and to compare the findings
with the surveys carried out between 1981-1985. This
would provide valuable information on the current status
of the stock and provide an indication of the resources
required to conduct such strategic surveys on other river
catchments in the North West Region of the National Rivers Authority
