Bargaining Models and Identifying the Wage Equation
It is commonly asserted that the standard wage equation derived from bargaining theory cannot be identified. Here, it is argued that the case for this alleged failure rests on an outmoded definition of identification. Newer concepts based on non-stationarities, cointegration and reduced rank are appropriate. An empirical example applying these concepts shows that the standard model can be derived and that far from being underidentified, it is actually overidentified.
A Super-Earth Orbiting the Nearby Sun-like Star HD 1461
We present precision radial velocity data that reveal a Super-Earth mass
planet and two probable additional planets orbiting the bright nearby G0V star
HD 1461. Our 12.8 years of Keck HIRES precision radial velocities indicate the
presence of a 7.4M_Earth planet on a 5.77-day orbit. The data also suggest, but
cannot yet confirm, the presence of outer planets on low-eccentricity orbits
with periods of 446.1 and 5017 days, and projected masses (M sin i) of 27.9 and
87.1M_Earth, respectively. Test integrations of systems consistent with the
radial velocity data suggest that the configuration is dynamically stable. We
present a 12.2-year time series of photometric observations of HD 1461, which
comprise 799 individual measurements, and indicate that it has excellent
long-term photometric stability. However, there are small amplitude variations
with periods comparable to those of the suspected 2nd and 3rd signals in the
radial velocities near 5000 and 446 days, thus casting some suspicion on those
periodicities as Keplerian signals. If the 5.77-day companion has a
Neptune-like composition, then its expected transit depth is of order ~0.5
millimags. The geometric a priori probability of transits is ~8%. Phase-folding
of the ground-based photometry shows no indication that transits of the
5.77-day companion are occurring, but high-precision follow-up of HD 1461
during upcoming transit phase windows will be required to definitively rule out
or confirm transits. This new system joins a growing list of solar-type stars
in the immediate galactic neighborhood that are accompanied by at least one
Neptune- (or lower) mass planets having orbital periods of 50 days or less.Comment: 33 pages, 7 figure

Rational expectations and near rational alternatives: How best to form expectations
Learning rules are increasingly being used in macroeconomic models. However one criticism that has been levelled at this assumption is that the choice of variables for inclusion in the learning rule, and the actual specification of the learning rule itself, is arbitrary. In this paper we test how important the particular learning rule specification is by incorporating a battery of learning rules into a large-scale macro model. The model's dynamics are then compared to those from a version of the model simulated under rational expectations (RE). The results indicate that although there are large differences between the RE solution and each of the solutions under learning, differences amongst the learning rule solutions are minor JEL Classification: C53, E43, F33
Thermolysis of pentafluorophenyl allyl ether and related compounds
This work is concerned with the involvement of the two possible intramolecular Diels-Alder adducts which can be formed from a 2-allyl-3, 5-cyclohexadienone produced by the Claisen rearrangement of a phenylallyl ether. One of these adducts has been invoked to account for the ortho-ortho ' transformation. Pentafluorophenyl allyl ether was chosen as the starting material, as it was envisaged that the fluorine atoms would a) block enolisation in the dienone intermediates; b) make the proposed Diels-Alder reaction more favourable by furnishing an electron def icient diene; and c) would help to stabilise small ring systems in the product. The thesis is divided into five parts. Chapter one reviews the literature and traces the mechanistic development of the Claisen re arrangement and the ortho-ortho' transformation. In Chapters two and three the isolation and characterisation of aromatic, bicyclic and tricyclic decomposition products, from the two possible intramolecular Diels-Alder adducts, are discussed. Chapters four and five describe the Claisen rearrangement in penta-fluorophenyl 2-methylprop-2-enyl and pentafluorophenyl 2-methylbut-3-en-2-yl ethers and suggest that the products formed can be accounted for by a mechanistic scheme which could be general
Representation and Sensation—A Defence of Deleuze’s Philosophy of Painting
Deleuze’s philosophy of painting can be seen to pose certain challenges to a phenomenological approach to philosophy. While a phenomenological response to Deleuze’s philosophy is clearly needed, I show in this article how an approach taken in a recent paper by Christian Lotz proves inadequate. Lotz argues that through Deleuze’s refusal to accept the place of representation in art, he is unable to distinguish art from decoration, or to give a coherent account of how the content of art can be represented. I show that this criticism emerges from a misreading of the place of representation in Deleuze’s philosophy. I will argue that by failing to take account of some of the key features of Deleuze’s wider ontology, such as the importance of both the virtual and the actual for his analysis of objects, Lotz’s critique proves unsuccessful. In particular, I want to show that Lotz’s criticisms rest on a failure to attend to the systematic nature of Deleuze’s philosophy, and in particular, the place of Deleuze’s analysis of Bacon within the system as a whole. I will further show that Lotz’s phenomenological defence commits the fallacy of petitio principii, assuming the validity of the phenomenological method in order to justify the phenomenological approach
