Has the Stability and Growth Pact Impeded Political Budget Cycles in the European Union?
This paper examines whether there is a political budget cycle (PBC) in countries in the euro area. Using a multivariate model for the period 1999-2004 and various election indicators we find strong evidence that the Stability and Growth Pact has not restricted fiscal policy makers in the euro area in pursuing expansionary policies before elections. In an election-year â but not in the year prior to the election â the budget deficit increases. This result is in line with third generation PBC models, which are based on moral hazard. We also find a significant but small partisan effect on fiscal policy outcomes.fiscal policy, political budget cycle, Stability and Growth Pact
Special functions, transcendentals and their numerics
Cyclotomic polylogarithms are reviewed and new results concerning the special
constants that occur are presented. This also allows some comments on previous
literature results using PSLQ
Measuring Synchronicity and Co-movement of Business Cycles with an Application to the Euro Area
We develop multivariate measures of synchronicity and co-movement of business cycles. In addition to synchronicity, the co-movement measure takes differences between cycle amplitudes into account that have been overlooked in most previous studies. We apply the new measures to the euro area. Synchronicity and co-movement for the region as a whole do not exhibit a clear upward tendency. Although several countries saw the similarity of their business cycle vis-`a-vis the euro area reference cycle increase, national business cycles remain fairly diverse. Changes in business cycle amplitudes cause most of the observed change in cycle co-movement.business cycles, synchronisation, concordance, co-movement, cycle amplitudes, euro area
Are there Political Budget Cycles in the Euro Area?
This article examines whether there is a political budget cycle (PBC) in countries in the euro area. Using a multivari ate model for 1999â2004 and various election indicators we find strong evidence that, since the start of the Stability and Growth Pact, fiscal policy-makers in the euro area have pursued expansionary policies before elections. In an election year â but not in the year prior to the election â the budget deficit increases. This result is in line with third-generation PBC models, which are based on moral hazard. We also find a significant but small partisan effect on fiscal policy outcomes
Location and orientation of serotonin receptor 1a agonists in model and complex lipid membranes
Magic angle spinning (MAS) NMR has been used to investigate the location and orientation of five serotonin receptor 1a agonists (serotonin, buspirone, quipazine, 8-OH-DPAT, and LY-163,165) in single component model lipid and brain lipid membranes. The agonist locations are probed by monitoring changes in the lipid proton chemical shifts and by MAS-assisted nuclear Overhauser enhancement spectroscopy, which indicates the orientation of the agonists with respect to the 1,2-dioleoyl-sn-glycero-3-phosphocholine lipids. In the single component bilayer, the membrane agonists are found predominantly in the top of the hydrophobic chain or in the glycerol region of the membrane. Most of the agonists orient approximately parallel to the membrane plane, with the exception of quipazine, whose piperazine ring is found in the glycerol region, whereas its benzene ring is located within the lipid hydrophobic chain. The location of the agonist in brain lipid membranes is similar to the 1,2-dioleoyl-sn-glycero-3-phosphocholine lipid bilayers; however, many of the agonists appear to locate close to the cholesterol in the membrane in preference to the phospholipids
Neurotoxin injection in benign submandibular gland hypertrophy: A first choice treatment
Background
Various benign clinical entities with a symptomatology of hypertrophic submandibular glands like sialadenitis, sialadenosis, sialolithiasis, or an ageing neck have been described. Botulinum toxin type A is an elegant tool in the management of these conditions.
Methods
This article is an original article, describing the Munich Concept of treating persistent submandibular swelling with Botulinum Toxin Type A from aesthetic and functional aspect. To shrink the affected tissue, 15 Units of Botox or Xeomin are applied in a single injection technique and under ultrasound guidance into the glands. Therefore, the 100 Units vial is being diluted with 3.5 of NaCl.
Results
Intraglandular injections, using a specific dilution and dosage of the neurotoxin preparations, are very effective in the management of these swellings, offering safe and longâlasting results, with a high satisfaction rate. Our working group treated in the last 18âmonths 23 patients with benign, bilateral submandibular gland hypertrophies, which did not have any major complications.
Conclusion
As there is not yet described an ideal therapeutic strategy for the management of this symptomatology, we suggest, based on our experience, a concept with very promising results from functional and cosmetic aspect
Solidification behavior and thermal conductivity of bulk sodium acetate trihydrate composites with thickening agents and graphite
Branch-and-Price Solving in G12
The G12 project is developing a software environment for stating and solving combinatorial problems by mapping a high-level model of the problem to an efficient combination of solving methods. Model annotations are used to control this process.
In this paper we explain the mapping to branch-and-price solving. G12 supports the selection of specialised subproblem solvers, the aggregation of identical subproblems, automatic disaggregation when required by search, and the use of specialised branching rules. We demonstrate the benefits of the G12 framework on three examples: a trucking problem, cutting stock, and two-dimensional bin packing
