Socially optimal allocation of ATM resources via truthful market-based mechanisms

This is a position paper, complementing existing research on design of economic incentives for allocation of ATM resources and services. We show how to design mechanisms that can be used for the allocation of many different types of ATM resources, including tactical flow management slots and airport facility resources. In particular, we discuss the example of arrival management when multiple aircraft request the same landing time. The mechanisms we present are socially optimal (i.e., resources are distributed in the way that best serves the users community as a whole), truthful (i.e., each individual user has incentive to play fairly), and, under certain assumptions, individually rational (i.e., users lose nothing from entering the market). However, they are not budget balanced (i.e., the resource owner gains profit from the users' payments). Earlier, it was shown how to design individually rational, budget balanced and (sometimes) socially optimal mechanisms. We also discuss other possible desirable properties of resource allocation schemes, outlining directions for future research in the design of markets for ATM services. Many ATM resources may be put onto an open market (auction), where users would express interest in the resources by submitting bids for them. A bid for a resource is a measure - often monetary - of the willingness of the user to access the resource. Based on the bids, the resource owner will allocate the resources to the users and will charge the users according to the allocation. The price that a user pays for the resource may not necessarily be equal to the user's bid; in particular, the price may be negative, meaning that the user is getting paid for being allocated an unfavored resource. The exact meaning of the bids may vary from application to application. E.g., in the scheduling domain, the resources may be service time slots (for a more concrete example, think of tactical arrival slots to an airport), and the bid may represent the cost per minute that the user incurs while waiting (say, for an available landing time). For companies leasing space in an airport, the resources may be, e.g., possible locations of check-in desks, shops or cafeterias, and the bid may express a company's valuation of renting a particular spot. Overall, there is a great variety of places in the air traffic industry where the bidding-allocation-pricing procedures can be adopted to provide cost-based access to services and resources. A. Properties of mechanisms The rules that the resource owner follows when allocating the resources and establishing the charges play a crucial role in the process. Over the years, several desirable properties of the allocation-and-pricing mechanisms have been identified: social optimality (SO): the allocation should maximize benefit to the society. incentive compatibility (IC): no user shall benefit from lying. individual rationality (IR): each user should get a non- negative utility.
Assessment of Farm Financial Literacy among Jasmine Growers in Tamilnadu, India

The unique nature of farm financial management calls for farmer to act as an entrepreneur. Being an farm entrepreneur the farmer should have enough financial literacy for effective financial management. Apart from training on production, post-harvest and marketing NAIP had given some information on farm financial management. A study was conducted to assess the financial literacy of jasmine farmers. Standardized knowledge test was employed to assess the financial literacy of farmers. For that, 100 farmers from Erode and 100 famers from Madurai district was surveyed. The collected data were analyzed using percentage analysis, multiple regression and factor analysis. It was concluded that, Erode farmers has high financial literacy than Madurai farmers. The results revealed that, age, education, experience, farm income, years of relationship with the bank, size of landholding, frequency of bank visit and bank account were significantly influenced the financial literacy of farmer. Key words: Financial literacy, NAIP, knowledge test and factor analysis

The Role of Agents in Private Entrepreneurial Finance

We examine theory and evidence on agents in private–market entrepreneurial financings. After controlling for the endogenous issuer–agent matching and a whole host of other controls, the empirical findings in this paper indicate that agents attract more investors, broaden the geographic investor and capital base, and increase the percentage of investors and capital from investors that are more vulnerable to the costs of information asymmetry. We also find that more capable agents generally provide more valuable benefits to private entrepreneurial firm financings than less capable agents, and that increasing the number of agents in a financing further increases value to issuing firms.
Monte Carlo simulations of thermal fluctuations in moderately damped Josephson junctions: Multiple escape and retrapping, switching- and return-current distributions, and hysteresis

A crossover at a temperature T* in the temperature dependence of the width sigma of the distribution of switching currents of moderately damped Josephson junctions has been reported in a number of recent papers, with positive d sigma/dT and IV characteristics associated with underdamped behavior for lower temperatures T T*. We have investigated in detail the behavior of Josephson junctions around the temperature T* by using Monte Carlo simulations including retrapping from the running state into the supercurrent state as given by the model of Ben-Jacob et al. [Phys. Rev. A 26, 2805 (1982)]. We develop discussion of the important role of multiple escape and retrapping events in the moderate-damping regime, in particular considering the behavior in the region close to T. We show that the behavior is more fully understood by considering two crossover temperatures and that the shape of the distribution and sigma(T) around T*, as well as at lower T< T*, are largely determined by the shape of the conventional thermally activated switching distribution. We show that the characteristic temperatures T* are not unique for a particular Josephson junction but have some dependence on the ramp rate of the applied bias current. We also consider hysteresis in moderately damped Josephson junctions and discuss the less commonly measured distribution of return currents for a decreasing current ramp. We find that some hysteresis should be expected to persist above T*. We highlight the importance, even well below T*, of accounting properly for thermal fluctuations when determining the damping parameter Q.
The effect of sporting success and management failure on attendance demand in the Bundesliga: a revealed and stated preference travel cost approach

ABSTRACT This study examines the private consumption benefits of sports attendance using revealed and stated preference data from 28 Football Bundesliga teams across three divisions. Survey respondents were presented with positive (sporting success) and negative (management failure) scenarios and asked for the number of game trips if each scenario occurred. The results of a pooled random effects Poisson model show that travel costs and ticket price have a significant negative effect on the number of home game trips. The weighted consumer surplus per game trip including travel costs and ticket prices is €345. Consumer surplus per game trip was found to change by €41 (first division) and €98 (second and third division) if the positive scenario occurred and by €39 if the negative scenario occurred.
Relative Performance of Diploid and Triploid Catchable Rainbow Trout Stocked in Idaho Lakes and Reservoirs

Abstract Idaho Department of Fish and Game hatcheries stock predominantly sterile triploid (3n) rainbow trout Oncorhynchus mykiss to provide sportfishing opportunities while minimizing the genetic risks to wild stocks. Triploid catchable-sized rainbow trout are stocked in over 500 water bodies across Idaho annually, but there remains some uncertainty regarding the performance of triploid rainbow trout relative to their diploid (2n) counterparts. We examined the relative survival, growth, and returns of diploid and triploid all-female catchable rainbow trout across 13 lakes and reservoirs. Most reservoirs showed higher returns of 2n rainbow trout to anglers. In 2008, 3n rainbow trout returned on average at only 72% and 81% of the rates of 2n trout in gill nets and snout collection boxes, respectively, and the difference for both methods was statistically significant. Carryover of marked rainbow trout from 2008 was low or zero in most reservoirs. Where there was carryover, snout collection boxes suggested t.

Characterization and Qualitative Analysis of Some Nigerian Clay Deposits for Rafractory Applications

The characterization of some Nigerian clay deposits has been carried out by employing fourdifferent characterization techniques.The relative proportions of the constituent compounds, the morphology and the phase identification of the different clays were determined by using X-Ray Fluorescence (XRF), Scanning Electron Microscopy/Energy Dispersive Spectroscopy (SEM/EDS), X-Ray Diffraction (XRD)and Transmission Electron Microscopy (TEM)analyses. The clays obtained from the various deposits were prepared for the analyses, using the standard procedure and the results obtained were compared to confirm the consistency and reliability of the different methods employed. The results obtained revealed the various desirable (SiO2 and Al2O3) and deleterious (Fe2O3, K2O and MgO) compounds contained in the clay samples, in the various proportions. The appropriate purification technique necessary for preparing the clays for refractory applications were therefore identified.
Bubble Motion in a Converging–Diverging Channel

The migration of a bubble inside a two-dimensional converging-diverging channel is investigated numerically. A parametric study is conducted to investigate the effects of the Reynolds and Weber numbers and the amplitude of the converging-diverging channel. It is found that increasing the Reynolds number and the amplitude of the channel increases the oscillation of the bubble and promotes the migration of the bubble toward one of the channel wall. The bubble undergoes oblate-prolate deformation periodically at the early times, which becomes chaotic at the later times. This phenomenon is a culmination of the bubble path instability as well as the Segre-Silberberg effect.
Common Information in Carry Trade Risk Factors

Carry returns have been widely observed in the FX market. This study exploits the common information embedded in several factors previously identified as relevant to carry trade returns. We find that the extracted common factor successfully models the time series and cross-sectional characteristics of carry returns. Empirical evidence is presented that the common factor produces smaller pricing errors than other well known factors, such as innovations of exchange rate volatility and the downside stock market excess return. Our results also suggest that stock market risk is somewhat segmented from FX market risk.
Opportunistic Strategies for Capture and Storage of Prey of Two Species of Social Wasps of the Genus Polybia Lepeletier (Vespidae, Polistinae, Epiponini)

The foraging activity in social wasps is complex behavior that involves the ability to locate and transport the resources necessary for the colony. The activity is opportunistic and generalist, sometimes adapting to the availability of the resources when the colonies are exposed to critical environmental conditions. The aim of this study was to evaluate the opportunistic behavior of two species of wasps of the genus Polybia for the capture and storage of prey in the form of flights of winged. Five colonies of Polybia occidentalis (Olivier) and two colonies of Polybia paulista (L.) were collected. Six of them contained stored winged of termites, and one contained winged of ants. The results indicated that these two species practice an opportunistic foraging strategy and are able to store large quantities of protein resources in their colonies.

Magnetic tweezers for intracellular applications

We have designed and constructed a versatile magnetic tweezer primarily for intracellular investigations. The micromanipulator uses only two coils to simultaneously magnetize to saturation micron-size superparamagnetic particles and generate high magnitude constant field gradients over cellular dimensions. The apparatus resembles a miniaturized Faraday balance, an industrial device used to measure magnetic susceptibility. The device operates in both continuous and pulse modes. Due to its compact size, the tweezers can conveniently be mounted on the stage of an inverted microscope and used for intracellular manipulations. A built-in temperature control unit maintains the sample at physiological temperatures. The operation of the tweezers was tested by moving 1.28 μm diameter magnetic beads inside macrophages with forces near 500 pN.
Financial Markets' Governance, Transparency and Informational Efficiency: Role of IfRS Norms, Auditors and Financial Analysts

This article explores the informational role of three essential modern financial markets actors such IFRS norms, the Big”4” and the financial analysts for a panel of emergent and developed countries during the period from 2001 to 2010. We hypothesis that these mechanisms help improving the quality of specific information incorporated into stock prices measured by the stock price synchronicity (SPS). The main result is that both financial analyst’s coverage and IFRS adoption's effects seem to be stronger for emerging than developed markets. The results also show a negative relationship between auditors’ opinion and coefficient of determination (R2).
Rethinking Industrial Policy for Low Income Countries

The governments of low income countries should be giving more attention to ‘industrial policy’ than they and the aid donors have given in the past quarter century. (‘Industrial policy’ means any sectorally or activity-targeted interventions, including in agriculture and services.) The first step is to discard the common assumption that industrial policy is about ‘picking winners’. The second step is to realize that industrial policy can be done ‘big’ or ‘small’, and by ‘leading the market’ or by ‘following the market’. It can be tailored to the available resources and state capacity. The third step is to see that the key issues of industrial policy are less to do with ‘what activities should be encouraged? ’, or ‘what sorts of policy instruments are best? ’, and more to do with, ‘how do we organize a process of discovery of sensible objectives and policies? ’, and ‘how do we organize a constant nudging of producers to upgrade, diversify, link up with foreign firms? ’ (where the nudging effort has to be targeted at some activities and sectors more than others). The paper illustrates with East Asian examples. One of the good effects of the current global crisis is that it has shaken confidence in the virtues of lightly regulated markets and free capital movements, and opened the way to a less ideologically charged debate about the role of the state in development—in which thinking is not precluded by easy jeers like ‘governments can't pick winners’ or ‘maybe the East Asians can do it but you can’t, so you have nothing to learn about industrial policy from them’.
Tasmanian School of Business and Economics University of Tasmania Discussion Paper Series N 2017-09 Divergence of Opinion and Long-Run Performance of Private Placements : Evidence from the Auction Market

In this paper, we propose and construct a direct measure of investors' divergence of opinion based on auction bids data of the private placements in China. We nd that the rms with higher bids dispersion generate lower long-run stock returns after the issuance of private placements. This e ect is economically signi cant and robust when controlling for market discount, earnings management, analysts forecast dispersion, and self-selection bias. Moreover, this negative relation is stronger for stocks with more stringent short-sale constraints. Our ndings therefore provide strong evidence in support of the Miller (1977)'s divergence of opinion hypothesis. JEL classi cation: D44, G12, G14.
Antimicrobial screening of Plectranthus madagascariensis and P. neochilus extracts

Natural products are widely used as traditional medicines and are a common source of bioactive molecules for the treatment of bacterial infections. In particular, some plants of the genus Plectranthus (Lamiaceae) have demonstrated several applications, including the treatment of various infections. In this work, aqueous, acetonic and methanolic extracts of P. madagascariensis and P. neochilus were prepared using several extraction methods (infusion, decoction, maceration, microwave- and ultrasoundassisted and supercritical fluids). All extracts were screened for their antimicrobial activity against Gram positive bacteria (Enterococcus faecalis, Staphylococcus aureus, Bacillus subtilis and Mycobacterium smegmatis) and Gram negative bacteria (Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli) and two yeast (Candida albicans and Saccharomyces cerevisiae) strains. The P. madagascariensis acetonic extracts obtained using ultrasound and maceration methods and P. neochilus acetonic extract obtained by ultrasound technique showed activity against the five tested Gram positive bacteria (5‒24 mm of inhibition zone using the well diffusion test). The antimicrobial activity was further evaluated by the microdilution method (MIC values were between 250‒0.49 μg/mL) and the bioautography assay against S. aureus. The P. madagascariensis ultrasound acetonic extract was the most active extract against all the tested Gram positive bacteria (MIC values ranged between 31.25 - 0.49 μg/mL). It was also active against resistant MRSA and VRE strains (MIC values ranged between 31.25-0.98 μg/mL). The S. aureus bioautography assay showed that the more polar compounds were the responsible for the antimicrobial activity.
A pyrazolate-bridged cyclic tetranuclear copper(II) complex: synthesis, crystal structure and magnetic properties

A new pyrazolate-bridged tetranuclear copper(II) complex [{CuL(H2O)}4]·12H2O (H2L = 5-methoxycarbonylpyrazole-3-carboxylic acid) was synthesized and its crystal structure determined. The molecule has C2 symmetry and consists of four copper atoms bridged by four planar L ligands through the nitrogen atoms of the pyrazole groups to form a (–Cu–N–N–)4 12-membered ring. The co-ordination of each copper is distorted square planar. The basal plane of each copper atom is nearly parallel to a neighbouring pyrazole plane and perpendicular to another neighbouring pyrazole plane. In the crystal there is a hydrogen-bond network between water molecules and carboxylate groups which may control the packing. The magnetic properties of the complex have also been investigated down to 5 K. The fitting of the experimental data using a Heisenberg Hamiltonian shows that the exchange interaction between the copper atoms propagated through the monopyrazolate bridge is antiferromagnetic with J=–12.34 cm–1. The reason for this small value relative to those in di-µ-pyrazolato-dicopper(II) complexes is discussed.
