description: The study investigates new strategies of football clubs in function of last few years’ trends in European football leagues. There were many changes in international professional football during the last 10-15 years that had significant effect on the success of certain clubs. We show empirical evidences about these effects based on data about revenues, transfer balance, financial and sport successes. We focus on Western European leagues and classify clubs based on their business and sport strategies.

description: A study of differential elliptic event anisotropies (v_2) of charged particles and high-pt pions in 158 AGeV/c Pb+Au collisions is presented. Results from correlations with respect to the event plane and from two-particle azimuthal correlations are compared. The latter give systematically higher v_2 values at pt>1.2GeV/c providing possibly an evidence of a non-flow semihard component.

Dynamical gravastars may evade no-go results for exotic compact objects, together with further analytical and numerical results for the dynamical gravastar model

Publisher: name: arXiv
Year: 2023
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Using graphs plotted from the Mathematica notebooks posted with our paper ``Dynamical Gravastars'', we show that a dynamical gravastar has no hard surface, and that a second light sphere resides in the deep interior where there is maximum time dilation. These facts may permit dynamical gravastars to evade no-go results for exotic compact objects relating to light leakage inside the shadow, and nonlinear instabilities arising from an interior light sphere. Testing these surmises will require further detailed modeling calculations, beyond what we commence in this paper, using the numerical dynamical gravastar solution. We also discuss the effect of replacing the sigmoidal function in the gravastar calculation by a unit step function, and we analyze why the dynamical gravastar evades the singularities predicted by the Penrose and Hawking singularity theorems, despite satisfying both the null and strong energy conditions. We then give a simplified two-step process for tuning the initial value $ν(0)={\rm nuinit}$ to achieve $ν(\infty)=0$, and give exact integrals for the pressure differential equation in terms of $ν(r)$ in the interior and exterior regions. Finally, we briefly discuss an extension of the model that includes an external shell of massive particles.

description: The quantum capacity of a noisy quantum channel determines the maximal rate at which we can code reliably over asymptotically many uses of the channel, and it characterizes the channel's ultimate ability to transmit quantum information coherently. In this paper, we derive single-letter upper bounds on the quantum and private capacities of quantum channels. The quantum capacity of a quantum channel is always no larger than the quantum capacity of its extended channels, since the extensions of the channel can be considered as assistance from the environment. By optimizing the parametrized extended channels with specific structures such as the flag structure, we obtain new upper bounds on the quantum capacity of the original quantum channel. Furthermore, we extend our approach to estimating the fundamental limits of private communication and one-way entanglement distillation. As notable applications, we establish improved upper bounds to the quantum and private capacities for fundamental quantum channels of interest in quantum information, some of which are also the sources of noise in superconducting quantum computing. In particular, our upper bounds on the quantum capacities of the depolarizing channel and the generalized amplitude damping channel are strictly better than previously best-known bounds for certain regimes.

description: Given an infinite graph $\GI$ quasi-transitive and amenable with maximum degree $\D$, we show that reduced ground state degeneracy per site $W_r(\GI,q)$ of the q-state antiferromagnetic Potts model at zero temperature on $\GI$ is analytic in the variable 1/q, whenever $|2\D e^3/q|< 1$. This result proves, in an even stronger formulation, a conjecture originally sketched in [KE] (Kim and Enting, 1979) and explicitly formulated in [ST] (Shrock and Tsai,1997), based on which a sufficient condition for $W_r(\GI,q)$ to be analytic at 1/q=0 is that $\GI$ is a regular lattice.

A third-party game is trained on a black-box time-series, and is then run into the future to extract next-step and multi-step predictions. In addition to the possibility of identifying profit opportunities, the technique may prove useful in the development of improved risk management strategies.

description: The NaNO$_{2}$ nanocomposite ferroelectric material in porous glass was studied by neutron diffraction. For the first time the details of the crystal structure including positions and anisotropic thermal parameters were determined for the solid material, embedded in a porous matrix, in ferro- and paraelectric phases. It is demonstrated that in the ferroelectric phase the structure is consistent with bulk data but above transition temperature the giant growth of amplitudes of thermal vibrations is observed, resulting in the formation of a "premelted state". Such a conclusion is in a good agreement with the results of dielectric measurements published earlier.

description: In this work, we investigate the quantum motions of non-relativistic particles interacting with a potential in the presence of the Aharonov-Bohm (AB) flux field within a topological defect geometry, for example, space-time with a distortion of a vertical line into a vertical spiral. We begin by deriving the radial Schrödinger wave equation, incorporating an anharmonic oscillator potential, which is a superposition of a harmonic oscillator and an inverse square potential, along with a constant term. The eigenvalue solution is obtained through the confluent Heun equation focusing on the ground state energy level and the radial wave function for the radial mode $n=1$ as an example and analyze the results. Subsequently, we use these results in molecular potential models, considering pseudoharmonic and shifted pseudoharmonic potentials. The derived eigenvalue solutions provide insights into the behavior of particles within these potentials. Expanding our exploration, we study the quantum system featuring only an inverse square potential in the presence of the quantum flux field in the same geometry background. Employing the same procedure, we determine the ground state energy level and the radial wave function. Notably, our findings reveal that the eigenvalue solutions are significantly influenced by the topological defect characterized by the parameter $β$, and the quantum flux field $Φ_{AB}$. This influence manifests as a shift in the energy spectrum, drawing parallels to the gravitational analog of the Aharonov-Bohm effect.

description: Surface codes are a promising method of quantum error correction and the basis of many proposed quantum computation implementations. However, their efficient decoding is still not fully explored. Recently, approaches based on machine learning techniques have been proposed by Torlai and Melko as well as Varsamopoulos et al. In these approaches, a so called high level decoder is used to post-correct an underlying decoder by correcting logical errors. A significant problem is that these methods require large amounts of training data even for relatively small code distances. The above-mentioned methods were tested on the rotated surface code which encodes one logical qubit. Here, we show that they are viable even for the toric surface code which encodes two logical qubits. Furthermore, we explain how symmetries of the toric code can be exploited to reduce the amount of training data that is required to obtain good decoding results. Finally, we compare different underlying decoders and show that the accuracy of high level decoding noticeably depends on the quality of the underlying decoder in the realistic case of imperfect training.

description: We present rigorous solution of problems of tunneling with dissipation and decoherence for a spin of an atom or a molecule in an isotropic solid matrix. Our approach is based upon switching to a rotating coordinate system coupled to the local crystal field. We show that the spin of a molecule can be used in a qubit only if the molecule is strongly coupled with its atomic environment. This condition is a consequence of the conservation of the total angular momentum (spin + matrix), that has been largely ignored in previous studies of spin tunneling.

description: Motivated by the transformative impact of deep neural networks (DNNs) in various domains, researchers and anti-virus vendors have proposed DNNs for malware detection from raw bytes that do not require manual feature engineering. In this work, we propose an attack that interweaves binary-diversification techniques and optimization frameworks to mislead such DNNs while preserving the functionality of binaries. Unlike prior attacks, ours manipulates instructions that are a functional part of the binary, which makes it particularly challenging to defend against. We evaluated our attack against three DNNs in white- and black-box settings, and found that it often achieved success rates near 100%. Moreover, we found that our attack can fool some commercial anti-viruses, in certain cases with a success rate of 85%. We explored several defenses, both new and old, and identified some that can foil over 80% of our evasion attempts. However, these defenses may still be susceptible to evasion by attacks, and so we advocate for augmenting malware-detection systems with methods that do not rely on machine learning.

description: The concept of $typed$ $topology$ is introduced. In a typed topological space, some open sets are assigned "types", and topological concepts such as closure, connectedness can be defined using types. A finite data set in $R^2$ is a typically typed topological space. Clusters calculated by the DBSCAN algorithm for data clustering can be well represent in a finite typed topological space. Other concepts such as tracks, port (starting points), type-p-connectedness, p-closure-connectedness, indexing, branches are also introduced for a finite typed topological space. Finally, $left-r$ and $up-left-r$ type open sets are introduced for data sets in $R^2$, so that tracks, port, branches can be calculated.

Competition between anisotropy and superconductivity in organic and cuprate superconductors
Creators: name: Schneider, T.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: We analyze the empirical correlation between the zero temperature penetration depth $λ_{c}(0) $ and the corresponding normal state DC conductivity $σ_{c}^{DC}$, measured slightly above the transition temperature $T_{c}$, in different classes of quasi two-dimensional superconductors, including cuprates and organics. For this purpose we invoke the scaling theory of quantum and finite temperature critical phenomena. Important implications are: Superconductivity in the organic and cuprate superconductors is a genuine three dimensional (3D) phenomenon. The competition between anisotropy and superconductivity destroys the latter in the 2D limit even in the ground state. The data uncovers the flow to quantum criticality, including the 2D quantum superconductor to insulator (2D-QSI) and the 3D quantum superconductor to normal state (3D-QSN) transition. This flow gives a clear perspective of the regimes where quantum fluctuations are essential and mean-field treatments fail. Thus, a detailed account of the flow from mean-field to 2D-QSI criticality in organics and the crossover from the 2D-QSI to the 3D-QSN critical point in cuprates is a challenge for microscopic theories attempting to solve the puzzle of superconductivity in these materials.

description: In this chapter we review the state-of-the-art of black holes in asymptotically safe gravity. After a brief recap of the asymptotic safety program, we shall summarize the features of asymptotic-safety-inspired black-hole models that have been constructed in the past by the so-called renormalization group improvement. Specifically, we will discuss static configurations, both in spherically- and axially-symmetric settings, the role played by the cosmological constant, and the impact of the collapse dynamics in determining black-hole configurations realized in Nature. In particular, we will review how quantum gravity could modify the Buchdahl limit and the corresponding conditions to form ultra-compact objects and Planckian black holes. We will then proceed by describing the most recent developments, particularly those aiming at making model building in asymptotic safety more rigorous and free from ambiguities. These include self-consistent and coordinate-independent versions of the renormalization group improvement, and next steps to fill the gap between model building and renormalization group computations in asymptotic safety. Finally, we will focus on a selection of results that have been obtained from first-principle calculations or arguments, within and beyond asymptotic safety. Concretely, we will review the state-of-the-art in determining black-hole entropy in asymptotic safety from a microstate counting, and progress in deriving the quantum-corrected Newtonian potential. We will discuss how in quantum gravity theories linked to a gravitational path integral singularity resolution could be achieved by a dynamical suppression of singular configurations. Finally, we will show that -- independent of the specific ultraviolet completion of gravity -- asymptotic modifications to Schwarzschild black holes are strongly constrained by the principle of least action at large distance scales.

description: The sports program of the professional higher education focusing on the leisure sports opportunities. New needs, change in taste and new leisure habits of the young generation should be taken into account to design the University’s leisure sports program. In my study I was dealing with a questionnaire survey investigating the attitude of the students of the University of Debrecen to leisure sports, and the students’ opinions about their own physical status. Data collection was completed on a paper based questionnaire, 42 closed-type questions were included and a total of 213 students completed it. In conclusion I found that the students are satisfied with their physical states although not many of them do sport on a regular basis. I revealed the primary excuses for neglecting sports: lack of time, laziness and timetable discrepancies. These findings make it imperative that by avoiding the existing discrepancies the students be provided the widest range of time in their time tables available for physical activities.

Using numerical methods we construct self-consistent solutions of the corresponding system of coupled integral-differential equations and study dependencies of the scalar field of the kink and the normalizable fermion bound states on the values of the values of the parameters of the model. We show that the backreaction of the localized fermions significantly modifies the solutions, in particular it results in spatial oscillations of the profile of the kink and violations of the reflection symmetry of the configuration.

Semiclassical systems being invariant under Lie groups are considered. An infinitesimal analog of group relation is written. Sufficient conditions for reconstructing semiclassical group transformations (integrability of representation of Lie algebra) are discussed. The obtained results may be used for mathematical proof of Poincare invariance of semiclasical Hamiltonian field theory and for investigation of quantum anomalies.

description: Abstract The study explores the implementation of corporate governance, accountability, and transparency (the Core Constructs) within UK SME charities to provide the most sort after answers to address the endless criticisms, demands for scrutiny, and requests for accountability and transparency to enhance their performance and credibility. This area of study is sparse on Small and Medium-sized charities, very little has been written on corporate governance, on occasions coupled with accountability or transparency but never with both. Nothing similar to this study has been done. The study seeks to investigate whether UK Small and Medium-sized charities implement effective corporate governance within their organisations, also to deduce whether Small and Medium-sized charities operate in the “Best-in-Class” area/zone implementing best practices, of accountability and transparency. The methods used to investigate this were the application of semi-structure interviews, survey-questionnaires, and the examinations of Trustees’ annual reports of the UK Small and Medium-sized charities incorporated from the sample, and further implemented triangulation to verify the results. The key findings revealed that the results provided similarity between the semi-structured interviews and the online questionnaires, while the annual reports did not match the findings of semi-structured interviews and the online questionnaires. The semi-structured interviews, the online questionnaires and annual reports revealed that different non-standard corporate governance practises are employed across UK Small and Medium-sized charities. The significance of the study is that the UK Small and Medium-sized charities do not operate within or could be classed within the “Best-in-Class” arena. Therefore, deduction could be made that the ‘Core Constructs’, corporate governance, accountability, and transparency, have not been effectively implemented, within the UK Small and Medium-sized charities.

description: The sport has significant role in the changes of the genders relation and helped to transform the conception of the sexes during the last fifty years. The women started to do conventionally male sports; the newest event was the ski jumping for female athletes at the Olympic Games of Soci. The gender stereotypes in the women sports can be stronger or weaker depending on the success or on the water haul. This phenomenon helps us to understand the new conceptions of the sexes in the context of the relationships of genders.

description: This paper is concerned with noisy matrix completion--the problem of recovering a low-rank matrix from partial and noisy entries. Under uniform sampling and incoherence assumptions, we prove that a tuning-free square-root matrix completion estimator (square-root MC) achieves optimal statistical performance for solving the noisy matrix completion problem. Similar to the square-root Lasso estimator in high-dimensional linear regression, square-root MC does not rely on the knowledge of the size of the noise. While solving square-root MC is a convex program, our statistical analysis of square-root MC hinges on its intimate connections to a nonconvex rank-constrained estimator.

description: We present VLT-UVES echelle spectroscopy of the HI and CIV absorption in the spatially-extended Lyman-alpha emission around two high-redshift radio galaxies 0200+015 (z=2.23) and 0943-242 (z=2.92). The absorbers in 0943-242 exhibit little additional structure compared with previous low-resolution spectroscopy and the main absorber is still consistent with HI column density of ~10^19 cm^-2. This is consistent with a picture in which the absorbing gas has low density and low metallicity and is distributed in a smooth absorbing shell located beyond the emission-line gas. However, the main absorbers in 0200+015 are very different. The previous single absorber fit of HI column density \~10^19 cm^-2, now splits into two ~4 x 10^14 cm^-2 absorbers which extend more than 15kpc to obscure additional Ly-alpha emission coincident with a radio lobe in these high-resolution observations. Although consistent with the shell-like distribution for the absorption systems, 0200+015 requires a much higher metal enrichment than 0943-242. The metallicity, inferred from the CIV absorption, is considerably lower in 0943-242 than in 0200+015. We explain these differences with an evolutionary scenario based on the size of the radio source. In both sources the HI absorption gas originates from either a gas-rich merger or pristine cluster gas which cools and collapses towards the centre of the dark matter halo. The higher metallicity in the larger radio source (0200+015) may be a result of a starburst driven superwind (concurrent with the triggering of the radio emission) which has engulfed the outer halo in this older source.

description: Nowadays the Hungarian government finances the sports in many ways; one of these grant forms is the group of 16 prioritized sports (biking, boxing, fencing, gymnastic, judo, track and field, kayak-canoeing, modern pentathlon, rowing, shooting, skating, swimming, tennis, table tennis, volleyball and wrestling) which are supported notably by the Hungarian Olympic Committee (HOC) till 2020. The purpose of the 1st sport vocational audit was to identify the current status of these sports, and also to create a database in many fields as a benchmark of the development. The sport management department of the Semmelweis University, Faculty of Physical Education and Sport Sciences (TF) contracted with the Hungarian Olympic Committee (HOC) in order to carry the sport vocational audit out. A sport develops if the numbers of the athletes grow or the results of the national teams are better. The coaches are the key persons in this development, if they could gather more children into the sport or they work better with the elite athletes the development has already done. It was examined the existence of the coach education programs; all the federations were running coaching programs for adults (OKJ) in both levels (coach assistant, coach). By 14 associations existed the first level of the higher education coaching program (BSc) and in 13 federations operated the MSc coaching program as well. All these coaching courses were common programs with schools, or universities. It was no evidence found that the federations run own coaching program but coaching license system existed in two sports at the time of the investigation.

description: Career planning and goal setting play a significant role in the life of elite athletes gaining critical relevance during the overlapping years with university studies. As athletic career contain a necessary end and cannot serve as a profession for life, all athletes shall go through modification period in their professional lives. The athletic career shall come to an end and elite athletes need to find another profession for which they need to prepare as well. The specialities of this undertake is that the peak or the progressive cycle of athletic career often times overlap in time with high school and university studies. This definitely challenges those young athletes who made the decision to continue their studies at the university level beside their athletic careers. The objective of this study is to explore the main factors influencing the simultaneous realisation of studies and elite sport careers during university years. Part of a complex research approach on dual career in sport this study is aimed to gain information about methods of athletes for managing their dual tasks, the perceived relationship of student athletes to their peers, teachers and coaches, and their position on the relevant policy regulations provided by the university environment. Following the development of research instruments, data collection was conducted by focus-group interviews at the University of Debrecen among student elite athletes receiving sport scholarships (N=15). Level of success in sport, sport type (individual and team) and gender distribution was taking into account. The results shall contribute to the development of a future research instrument in a form of a questionnaire to assess aspects of dual career of athletes in case of larger samples.

description: The high spectral resolution R about 45,000 provided by IGRINS (Immersion Grating INfrared Spectrometer) at MacDonald Observatory and R 100,000 achieved by CRIRES (CRyogenic high-resolution InfraRed Echelle Spectrograph) at VLT (Very Large Telescope) challenges the present knowledge of infrared spectra. aims We aim to predict the full infrared spectrum of molecular hydrogen at a comparable accuracy. methods We take advantage of the recent theoretical ab initio studies on molecular hydrogen to compute both the electric quadrupole and magnetic dipole transitions taking place within the ground electronic molecular state of hydrogen. results We computed the full infrared spectrum of molecular hydrogen at an unprecedented accuracy and derive for the first time the emission probabilities including both electric quadrupole ($ΔJ = 0, \pm$2) and magnetic dipole transitions ($ΔJ = 0$) as well as the total radiative lifetime of each rovibrational state. Inclusion of magnetic dipole transitions increases the emission probabilities by factors of a few for highly excited rotational levels, which occur in the 3-20 $μ$ range}

description: In this talk latest results from the analysis of e+e- pairs emitted in Pb+Au collisions at 40 AGeV/c and a combined analysis of all data available at 158 AGeV/c are presented. The enhancement of low-mass e+e- pairs (m_ee>0.2 GeV/c^2) with respect to the expected yield from hadron decays first reported at 158 AGeV/c is also found at 40 AGeV/c and is even larger there. Comparing to various theoretical models based on pi-pi-annihilation, the data can only be reproduced, if the properties of the intermediate rho in the hot and dense medium are modified. Theoretically, the modification is linked to baryon density rather than temperature. Constraints from hadron data taken at the same beam energies indeed indicate a fireball evolution along a trajectory of higher baryon density at 40 AGeV/c, consistent with the observed larger enhancement factor.

description: We discuss the possibility to employ the shot-noise measurements for the analysis of the energy resolved ballistic currents. Coulomb interactions play an essential role in this technique, since they lead to the shot-noise-suppression level which depends on the details of the energy profile.

description: To elucidate how the temperature dependence of the resistivity anisotropy of the cuprate superconductors changes with hole doping, both the in-plane and the out-of-plane resistivities (ρ_{ab} and ρ_{c}) are measured in a series of high-quality Bi_{2}Sr_{2-x}La_{x}CuO_{6+δ} (BSLCO) single crystals for a wide range of x (x = 0.23 - 1.02), which corresponds to the hole doping per Cu, p, of 0.03 - 0.18. The anisotropy ratio, ρ_{c}/ρ_{ab}, shows a systematic increase with decreasing p at moderate temperatures, except for the most underdoped composition where the localization effect enhances ρ_{ab} and thus lowers ρ_{c}/ρ_{ab}. The exact p dependence of ρ_{c}/ρ_{ab} at a fixed temperature is found to be quite peculiar, which is discussed to be due to the effect of the pseudogap that causes ρ_{c}/ρ_{ab} to be increasingly more enhanced as p is reduced. The pseudogap also causes a rapid growth of ρ_{c}/ρ_{ab} with decreasing temperature, and, as a result, the ρ_{c}/ρ_{ab} value almost reaches 10^6 in underdoped samples just above T_c. Furthermore, it is found that the temperature dependence of ρ_{c} of underdoped samples show two distinct temperature regions in the pseudogap phase, which suggests that the divergence of ρ_{c} below the pseudogap temperature is governed by two different mechanisms.

description: Sports organizations must prepare an annual report on their operation and assets, pursuant to the current Act on Accounting. However, when preparing this report, one must face the difficulty of defining the value intellectual assets and human resources represent, and the impossibility of its inclusion in financial statements. Therefore there is a significant difference between the value shown in accounting and the fair value of sports organizations.

description: Developing sport into an industry has become a fundamental interest and a noticeable approach in Hungary in recent years. A socalled economic orientation can also be observed in the field of leisure time sports, which was made into law in Hungary in 2011 allowing the support of sport organisations and resulting in a number of infrastructural developments in Hungary. A wide range of development opportunities remain open in sports. This evaluation aims to introduce what significant sport-investment projects have been implemented in the Northern Great Plain region in recent decades and what effects these investments have had. Surveys have been used to reveal whether these facilities originating from years of sport developments are sustainable and to what extent these are exploited for organising sport events. Based on responses provided by a number of sport facilities – including ones built in the past and also ones opened recently – it can be concluded that sport in itself cannot solve the issue of operation and possible economic growth. Considering these aspects, it is important to incorporate, not only in operation but also during planning, the idea that current facilities must „serve” not solely sport events as these in themselves will not make them profitable but they must remain open for all sorts of social events as well.

description: We study Berry curvature driven and Zeeman magnetic field dependent electric current responses of two-dimensional electron system with spin-orbit coupling. New non-dissipative component of the electric current occurring in the applied in-plane magnetic field is described. This component is transverse to the electric field, odd in the magnetic field, and depends only on one particular direction of the magnetic field defined by the spin-orbit coupling. We show that the effect can be observed in a number of systems with $C_{3v}$ symmetry.

The free energy of a quantum Sherrington-Kirkpatrick spin-glass model for weak disorder

description: We extend two rigorous results of Aizenman, Lebowitz, and Ruelle in their pioneering paper of 1987 on the Sherrington-Kirkpatrick spin-glass model without external magnetic field to the quantum case with a "transverse field" of strength $b$. More precisely, if the Gaussian disorder is weak in the sense that its standard deviation $v>0$ is smaller than the temperature $1/β$, then the (random) free energy almost surely equals the annealed free energy in the macroscopic limit and there is no spin-glass phase for any $b/v\geq0$. The macroscopic annealed free energy (times $β$) turns out to be non-trivial and given, for any $βv>0$, by the global minimum of a certain functional of square-integrable functions on the unit square according to a Varadhan large-deviation principle. For $βv<1$ we determine this minimum up to the order $(βv)^4$ with the Taylor coefficients explicitly given as functions of $βb$ and with a remainder not exceeding $(βv)^6/16$. As a by-product we prove that the so-called static approximation to the minimization problem yields the wrong $βb$-dependence even to lowest order. Our main tool for dealing with the non-commutativity of the spin-operator components is a probabilistic representation of the Boltzmann-Gibbs operator by a Feynman-Kac (path-integral) formula based on an independent collection of Poisson processes in the positive half-line with common rate $βb$. Its essence dates back to Kac in 1956, but the formula was published only in 1989 by Gaveau and Schulman.

description: Abstract: Growths of mechanization service supply have been considered generally frictionless outside Africa South of Sahara (SSA). However, the dominance of large tractors that are sparsely populated in SSA countries like Nigeria today suggests significant imperfections in tractor hiring service market due to technology indivisibility and low spatial mobility. Empirically testing market imperfections for scale-biased technologies like tractors has been challenging, partly due to the difficulty of separating the effect of marginal technology adoptions from intensive technology adoptions that potentially generate scale effects. We fill this knowledge gap by applying covariate matching, ordinary propensity score matching, as well as generalized propensity score matching methods to Nigerian household data. Tractor hiring service market in Nigeria is found imperfect, potentially due to the supply-side constraints. The effect of this imperfection is also sizeable; in the case of Nigeria, overcoming this imperfection can potentially increase farm households’ income by as much as 30%. This effect is from the marginal adoption of tractors alone, even without the potential scale effects from intensive tractor use upon adoption.
