description: We prove lower bounds on the number of product gates in bilinear and quadratic circuits that compute the product of two $n \cross n$ matrices over finite fields. In particular we obtain the following results: 1. We show that the number of product gates in any bilinear (or quadratic) circuit that computes the product of two $n \cross n$ matrices over $F_2$ is at least $3 n^2 - o(n^2)$. 2. We show that the number of product gates in any bilinear circuit that computes the product of two $n \cross n$ matrices over $F_p$ is at least $(2.5 + \frac{1.5}{p^3 -1})n^2 -o(n^2)$. These results improve the former results of Bshouty '89 and Blaser '99 who proved lower bounds of $2.5 n^2 - o(n^2)$.

description: Adsorption of one-third monolayer of Sn on an atomically-clean Si(111) substrate produces a two-dimensional triangular adatom lattice with one unpaired electron per site. This dilute adatom reconstruction is an antiferromagnetic Mott insulator; however, the system can be modulation-doped and metallized using heavily-doped p-type Si(111) substrates. Here, we show that the hole-doped dilute adatom layer on a degenerately doped p-type Si(111) wafer is superconducting with a critical temperature of 4.7 +- 0.3 K. While a phonon-mediated coupling scenario would be consistent with the observed TC, Mott correlations in the Sn-derived dangling-bond surface state could suppress the s-wave pairing channel. The latter suggests that the superconductivity in this triangular adatom lattice may be unconventional.

description: Merely by existing, all physical systems register information. And by evolving dynamically in time, they transform and process that information. The laws of physics determine the amount of information that a physical system can register (number of bits) and the number of elementary logic operations that a system can perform (number of ops). The universe is a physical system. This paper quantifies the amount of information that the universe can register and the number of elementary operations that it can have performed over its history. The universe can have performed no more than $10^{120}$ ops on $10^{90}$ bits.

description: In Finland, there are in total 347 000 family forest holdings over 2 hectares of productive forestland. Family forest owners number 737 000, which is 14 % of all Finnish citizens. Average size of a forest holding is 30 hectares and average age of a forest owner is 60 years. Family forestry without connection to agriculture or forest industry is not regarded in Finland as a business but financial investment. Because separate financial policies are applied to business investments and financial investments, structural instruments applied in agricultural farms or family companies cannot be used in family forestry. From the roundwood production point of view, the forest holding structure is increasingly regarded ineffective. A ministerial working group concluded in January 2012 the most effective ways (in effectivity order) to improve forest holding size and structure in Finland: 􀁸 Conditional concession for inheritance and donation tax for forest holdings 􀁸 Developing land consolidation arrangements for improving forest holding structure 􀁸 Conditinal concession for profit taxation from forest holding assignment 􀁸 Developing and increasing advise and education for transfer to next generation 􀁸 Allowing companies as forest owners to make in taxation reserves and forest deduction 􀁸 Enlargement and administration development of jointly owned forests 􀁸 Using state forests as incentives to establish jointly owned forests 􀁸 Advising heirs as forest owners to form private partnerships or jointly owned forests 􀁸 Developing forest renting. Working group proposals aim at improving profitability and sustainability of forestry as well as roundwood supply in Finland. However, only proposals on advise and education (4, 8), jointly owned forests (6, 7) and partly also land consolidation (2) seem to proceed in governmental decision making.

description: Background and purpose — There is no consensus regarding the optimal treatment of hip displacement in children with cerebral palsy (CP). This prospective study assessed the outcome of femoral and pelvic osteotomies for severe hip displacement in nonambulatory children and analyzed prognostic factors for outcome. Patients and methods — 31 nonambulatory children (20 boys), recruited from a population-based screening program, consecutively underwent unilateral (23) or bilateral (8) osteotomies and bilateral soft-tissue releases at a mean age of 6.1 years (2.2–9.9). The procedures were femoral varus osteotomy alone (20 hips) and combined Dega-type pelvic osteotomy and femoral osteotomy (19 hips). Final outcome was termed good if the patient had not undergone further bony surgery and migration percentage (MP) was < 50%. The mean follow-up time was 7.1 years (3.8–11). Results — The mean preoperative MP was 69% (36–100). The outcome was good in 22 patients (29 hips) and poor in 9 patients (10 hips). Mean time to failure was 3.6 years (1.0–6.0). GMFCS level V and high MP 1-year postoperatively were statistically significant risk factors for poor final outcome. There was a higher rate of good outcome after combined osteotomies compared with isolated femoral osteotomy, but the difference was not statistically significant (p = 0.2). Interpretation — Better primary correction was obtained after combined femoral and pelvic osteotomies than after isolated femoral osteotomy, indicating that combined osteotomies are the preferred method in hips with the most severe degrees of displacement. Prophylactic femoral osteotomy of the contralateral non-subluxated hip is hardly indicated.

Effects of Glaciation on Volcanism in Iceland

description: Volcanic eruption rates in Iceland during the last deglaciation increased 5--30 fold from the steady-state rates. This has been understood by the unloading of ice, which increases the decompression rates in the mantle, causing enhanced mantle melting rates. However, existing theoretical work cannot account for large variations of Rare Earth Element (REE) concentrations in the Icelandic lavas. Lavas erupted during the last deglaciation are depleted in REEs by up to 70\%; whereas, existing models can only produce at most 20\% depletion. This dissertation attempts to find the causes of this mismatch and provides the first models that take account of the diachronous response of volcanism to deglaciation. Numerical models of mantle flow and mantle melting response to the glaciation and deglaciation are developed. A time-lag sampler is incorporated to represent the time lag between the melt production at depths and the eruption on the Earth's surface due to finite rate of melt transport. The model results for the last deglaciation in Iceland show that the variations of REE concentrations are strongly dependent on the melt ascent velocity. This explains the REE concentration mismatch between the previous theoretical work and the observations. Comparison between the model results (timing of the bursts in volcanic eruptions, REE concentration variations, and volume proportions of the subglacial, finiglacial and postglacial eruptions) and the observational data suggests that the melt ascent velocity during the last deglaciation beneath Iceland is of the order of $\sim$100~$\text{m/year}$. The effects of glacial loading during the last glacial period on mantle melting are also investigated. It is found that glacial loading suppresses mantle melting and modulates the average REE concentrations in the melts due to the depth-dependent profile of mantle melting suppression. In addition, this dissertation explores how different deglaciation histories can result in different REE concentrations in the early-postglacial lavas. This may explain why lava shields formed during the Termination~II have different geochemical compositions from that formed during the Termination~I. Lastly, predictions for the future of the Icelandic volcanic eruption rates are made based on given estimated deglaciation rates of the current Icelandic glaciers.

description: We have studied the correlation among X-ray absorption, optical reddening and nuclear dust morphology in Seyfert 2 galaxies. Two main conclusions emerge: a) the Balmer decrement and the amount of X-ray absorption are anticorrelated on a wide range of column density: 10^{21} < N_H < 10^{24} atoms/cm/cm. The correlation does no longer apply to Compton-thick objects (N_H < 10^{24} atoms/cm/cm), although they span a comparable range in Balmer decrement; b) Compton-thin Seyfert 2s seem to prefer nuclear environments, which are rich of dust on scales of the hundreds parsecs. On the other hand, Compton-thick Seyferts exhibit indifferently ``dust-poor'' and ``dust-rich'' environments. These results support an extension of the Seyfert unification scenario (as recently proposed by Matt, 2000), where Compton-thick Seyfert 2s are observed through compact ``torii'', whereas Compton-thin ones are obscured by dust on much larger scales

description: Mitochondria are involved in numerous processes vital for cellular homeostasis, therefore, mitochondrial dysfunction can lead to a wide range of diseases. Understanding mitochondrial function in health and disease is crucial for the development of efficient therapies, for which targeting bioactive compounds to mitochondria is a promising strategy. The best characterised approach is to attach the bioactive moiety to a triphenylphosphonium cation (TPP), which drives membrane potential-dependent uptake into the organelle. However, there are still limitations associated with TPP-targeting, some of which I have attempted to overcome in this work. Firstly, I have investigated the use of labile linkers to connect bioactive moieties to the TPP cation, allowing their release from TPP once they are taken up by mitochondria. This strategy could allow the lock-in of compounds within mitochondria, a feature that is currently not routinely possible. Furthermore, this approach could minimise negative effects the TPP cation could have on the compound’s bioactivity. In order to select linker candidates, I have performed a bioinformatics analysis to investigate which structures are enzymatically cleaved inside mitochondria but are stable when crossing the plasma membrane and the cytosol. Then, I developed a fast screening method using coumarin fluorescence to test the stability of these candidates across multiple conditions. I have also tested the use of an ester bond to deliver a hydrophobic compound (an analogue of MitoQ10) to mitochondria, as well as the use of a cleavable mask to deliver a polar compound (a phosphate group which is charged at physiological pH). I have also addressed the lack of probes to measure mitochondrial membrane potential that could be used in vivo in live models, without the need for tissue homogenization. For that I used click chemistry with the goal of targeting two TPP precursors that would react inside mitochondria to generate labelled N2, which could then be detected externally in the expired gases. Finally, I have investigated whether TPP dications could be used to improve the uptake and retention of a hydrogen peroxide probe, MitoB, in cells and in vivo. These approaches have provided a number of insights into how to develop new mitochondria targeted compounds.

description: There are many situations of tension and conflict in Africa today. Most of them arise due to poor governance and this explains why there is a pertinent quest for a good system of governance where human rights are respected especially in Africa. Kwasi Wiredu is one of the authors who have explored this theme basing on the traditional African concepts of human rights and democracy. For him, by the fact of being a human being, each one is entitled to rights. This is complimented by the concept of a human person in the traditional Africa. However, these rights cannot flourish in poor and undemocratic political system and so, to Wiredu, consensual democracy with non-party system, which originates from African tradition, is the best government for African societies.This work therefore examines with a detached appreciation, the striking relevance of his views to make Africa a better place to live in. Wiredu argues that a return to the values of African traditional culture can contribute much in implementation of good governance and in protecting human rights.

description: Approximations of the Dirac delta distribution are commonly used to create sequences of smooth functions approximating nonsmooth (generalized) functions, via convolution. In this work, we show a priori rates of convergence of this approximation process in standard Sobolev norms, with minimal regularity assumptions on the approximation of the Dirac delta distribution. The application of these estimates to the numerical solution of elliptic problems with singularly supported forcing terms allows us to provide sharp $H^1$ and $L^2$ error estimates for the corresponding regularized problem. As an application, we show how finite element approximations of a regularized immersed interface method result in the same rates of convergence of its non-regularized counterpart, provided that the support of the Dirac delta approximation is set to a multiple of the mesh size, at a fraction of the implementation complexity. Numerical experiments are provided to support our theories.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Recently Polchinski and Strassler reproduced the high energy QCD scaling at fixed angles from a gauge string duality inspired in AdS/CFT correspondence. In their approach a confining gauge theory is taken as approximately dual to an AdS space with an IR cut off. Considering such an approximation (AdS slice) we found a one to one holographic mapping between bulk and boundary scalar fields. Associating the bulk fields with dilatons and the boundary fields with glueballs of the confining gauge theory we also found the same high energy QCD scaling. Here, using this holographic mapping we give a simple estimate for the mass ratios of the glueballs assuming the AdS slice approximation to be valid at low energies. We also compare these results to those coming from supergravity and lattice QCD.

description: Quantum information processing based on magnetic ions are considered potential candidates for applications because they can be modified and scaled up by a variety of chemical methods. For these systems to achieve individual spin addressability and high energy efficiency, we exploited the electric field as a tool to manipulate their quantum behaviours, functioning via spin-orbit coupling. A Ce:YAG single crystal was employed due to that rare-earth ions have strong spin-orbit coupling and with considerations regarding the dynamics and the symmetry requirements. The Stark effect of the Ce3+ ion was observed and measured. When demonstrated as a quantum phase gate, the electric field manipulation exhibited high efficiency which allowed up to 57 π/2 operations before decoherence with optimized field directions. It was also utilized to carry out quantum bang-bang control, as a method of dynamic decoupling, and the refined Deutsch-Jozsa algorithm. Our experiments highlighted rare-earth ions as potentially applicable qubits since they offer enhanced spin-electric coupling which enables high-efficiency quantum manipulation.

description: This paper presents and analyzes an incremental algorithm for the construction of Acyclic Non-deterministic Finite-state Automata (NFA). Automata of this type are quite useful in computational linguistics, especially for storing lexicons. The proposed algorithm produces compact NFAs, i.e. NFAs that do not contain equivalent states. Unlike Deterministic Finite-state Automata (DFA), this property is not sufficient to ensure minimality, but still the resulting NFAs are considerably smaller than the minimal DFAs for the same languages.

description: The interpretation of nuclear magnetic resonance (NMR) data is of interest in a number of fields. In Ögren [Eur. Phys. J. B (2014) 87: 255] local boundary conditions for random walk simulations of NMR relaxation in digital domains were presented. Here, we have applied those boundary conditions to large, three-dimensional (3D) porous media samples. We compared the random walk results with known solutions and then applied them to highly structured 3D domains, from images derived using synchrotron radiation CT scanning of North Sea chalk samples. As expected, there were systematic errors caused by digitalization of the pore surfaces so we quantified those errors, and by using linear local boundary conditions, we were able to significantly improve the output. We also present a technique for treating numerical data prior to input into the ESPRIT algorithm for retrieving Laplace components of time series from NMR data (commonly called $T$-inversion).

description: We have witnessed in the past decade the observation of a puzzling cosmic-ray excess at energies larger than $10$ GeV. The AMS-02 data published this year has new ingredients such as the bump around $300$ GeV followed by a drop at $800$ GeV, as well as smaller error bars. Adopting the background used by the AMS-02 collaboration in their analysis, one can conclude that previous explanations to the new AMS-02 such as one component annihilating and decaying dark matter as well as pulsars seem to fail at reproducing the data. Here, we show that in the right-handed neutrino portal might reside the answer. We discuss a decaying two-component dark matter scenario where the two-body decay products are right-handed neutrinos that have their decay pattern governed by the type I seesaw mechanism. This setup provides a very good fit to data, for example, for a conservative approach including just statistical uncertainties leads to $χ^2/d.o.f \sim 2.3$ for $m_{DM_1}=2150$ GeV with $τ_{1}=3.78 \times 10^{26}$ s and $m_{DM_2}=300$ with $τ_{2}=5.0 \times 10^{27}$ s for $M_N=10$ GeV, and, in an optimistic case, including systematic uncertainties, we find $χ^2/d.o.f \sim 1.12$, for $M_N = 10$ GeV, with $m_{DM_1}=2200$ GeV with $τ_{1}=3.8 \times 10^{26}$ s and $m_{DM_2}=323$ GeV with $τ_{2}=1.68 \times 10^{27}$ s.

description: The moving contact line paradox discussed in the famous paper by Huh and Scriven has lead to an extensive scientific discussion about singularities in continuum mechanical models of dynamic wetting in the framework of the two-phase Navier-Stokes equations. Since the no-slip condition introduces a non-integrable and therefore unphysical singularity into the model, various models to relax the singularity have been proposed. Many of the relaxation mechanisms still retain a weak (integrable) singularity, while other approaches look for completely regular solutions with finite curvature and pressure at the moving contact line. In particular, the model introduced recently in (Lukyanov, Pryer, Langmuir 2017) aims for regular solutions through modified boundary conditions. The present work applies the mathematical tool of compatibility analysis to continuum models of dynamic wetting. The basic idea is that the boundary conditions have to be compatible at the contact line in order to allow for regular solutions. Remarkably, the method allows to compute explicit expressions for the pressure and the curvature locally at the moving contact line for regular solutions to the model of Lukyanov and Pryer. It is found that solutions may still be singular for the latter model.

Identification of RBPMS as a smooth muscle master splicing regulator via association of its gene with super-enhancers

description: Alternative splicing (AS) is primarily regulated by regulatory RNA-binding proteins (RBPs). It has been suggested that a small number of master splicing regulators might control cell-specific programs and these regulators could be identified via the association of their genes with transcriptional super-enhancers. Using this approach, RNA Binding Protein with Multiple Splicing (RBPMS) was identified as a critical splicing regulator in vascular smooth-muscle cells (SMCs). RBPMS is strongly downregulated during SMC dedifferentiation and is responsible for nearly 20% of the AS changes during this transition as indicated by mRNA-Seq of rat PAC1 cells with RBPMS-manipulated levels. RBPMS overexpression also promoted splicing events that are usually only observed in tissue SMCs. RBPMS targeted a network of proteins involved in the cytoskeleton and cell-adhesions, machineries remodelled during the transition from contractile to motile-dedifferentiated SMCs. RBPMS directly regulated target exons with a positional bias depending upon whether acting as an activator or repressor, as indicated by RBPMS-maps, in vivo transfections with minigene reporters, RBPMS RNA binding mutant, MS2 artificial tethering and lastly in vitro binding assays. RBPMS controlled splicing and activity of other splicing and post-transcriptional regulators (MBNL1, MBNL2 and LSM14B) as well as the key SMC transcription factor Myocardin. Structure-function analyses revealed that the two major RBPMS isoforms (RBPMS-A and B) have differential activity, and that dimerization and RBPMS C- terminus are essential to RBPMS splicing activity. Yet, RBPMS RRM was insufficient for splicing. In fact, a core section of the C-terminus of RBPMS-B antagonized its repressor-splicing activity. Additionally, two threonine residues of RBPMS could be phosphorylated differentially modulating RBPMS isoforms activity. Therefore, this study provides the strongest evidence to date for a molecular function of RBPMS as a splicing-regulator, matching many of the expected criteria of a master regulator of AS in differentiated VSMCs.

description: Recently it was realized that linear optics and photo-detectors with feedback can be used for theoretically efficient quantum information processing. The first of three steps toward efficient linear optics quantum computation (eLOQC) was to design a simple non-deterministic gate, which upon post-selection based on a measurement result implements a non-linear phase shift on one mode. Here a computational strategy is given for finding non-deterministic gates for bosonic qubits with helper photons. A more efficient conditional sign flip gate is obtained.

Universal gas density and temperature profile

description: We present an analytic approach to predict gas density and temperature profiles in dark matter haloes. We assume that the gas density profile traces the dark matter density profile in outer parts of the haloes, as suggested by many hydrodynamic simulations. Under this assumption, the hydrostatic equilibrium uniquely fixes the two free parameters in the model, the mass-temperature normalization and the polytropic index, that determine the temperature profile. This enables us to predict a universal gas profile from any universal dark matter profile. Our results show that gas tracing dark matter in the outer parts of the haloes is inconsistent with gas being isothermal; on the contrary, it requires temperature to decrease slowly with radius, in agreement with observations. We compare our predictions for X-ray surface brightness profiles of the haloes and the mass-temperature relation with observations. We find that they are generally in a good agreement. We compare the universal profile with the beta profile and find that, although the beta profile gives a reasonable fit to our predicted profiles, the deviation from it can explain many of the observed trends, once we take into account the observational selection effects. Our model predicts that the mass-temperature relation does not follow the self-similar relation because of the mass-dependent halo concentration. We also predict surface brightness profiles of the Sunyaev-Zel'dovich (SZ) effect. We find that fitted to the beta profile the core radii and beta inferred from the SZ effect are systematically larger than those from the X-ray measurement.

description: In this study, a novel approach has been used for the efficient synthesis of tetrahydrodipyrazolopyridine derivatives (5a–m) via a four-component one-pot condensation reaction of aromatic aldehydes, hydrazinehydrate, ethyl acetoacetate, and ammonium acetate in the presence of KCC-1-npr-NH2-DPA as an advanced nano-catalyst in ethanol under reflux conditions at 30 min. For this purpose, mesoporous fibrous nano-silica functionalized by dipenicillamine as a novel nanocatalyst (KCC-1-npr-NH2-DPA) was synthesized using a hydrothermal protocol. KCC-1-npr-NH2-DPA nano-catalyst is easily recyclable eight times without the considerable loss of catalytic activity. Other remarkable features include the short reaction time, simple work-up procedure and providing excellent yields (89–98%) of the products under mild reaction conditions. Furthermore, the effects of solvent, concentration of catalyst, time and temperature for the synthesis of tetrahydrodipyrazolopyridine (5a) were studied.
Higgs-Mediated $B_{s,d}^0\toμτ, eτ$ and $τ\to3μ, eμμ$ Decays in Supersymmetric Seesaw Models

description: We study the rates allowed for the Higgs-mediated decays $B_{s,d}^0\toμτ, eτ$ and $τ\to μμμ, eμμ$ in supersymmetric seesaw models, assuming that the only source of lepton flavour violation (LFV) is the renormalization of soft supersymmetry-breaking terms due to off-diagonal singlet-neutrino Yukawa interactions. These decays are strongly correlated with, and constrained by, the branching ratios for $B_{s,d}^0\toμμ$ and $τ\to μ(e)γ.$ Parametrizing the singlet-neutrino Yukawa couplings $Y_ν$ and masses $M_{N_i}$ in terms of low-energy neutrino data, and allowing the flavour-universal soft masses for sleptons and for squarks, as well as those for the two Higgs doublets, to be different at the unification scale, we scan systematically over the model parameter space. Neutrino data and the present experimental constraints set upper limits on the Higgs-mediated LFV decay rates $Br(B_{s}^0\toμτ, eτ)\lsim 4\times 10^{-9}$ and $Br(τ\toμμμ, eμμ)\lsim 4\times 10^{-10}$.

description: We present the results of an all-sky search for continuous gravitational wave signals with frequencies in the 200-600 Hz range and frequency derivative (spindown) from -1e-8 through 1.11e-9 Hz/s. Together with the results from [1], this search completes the all-sky survey for frequencies between 20 to 600 Hz on O1 data. It also demonstrates the scalability of our search on a parameter space 26 times larger than previously considered. The results presented here complement the LIGO O2 data results [2,3] with comparable when not better sensitivity and do not rely on data with irregularities in the noise-subtraction procedure. We establish strict upper limits which hold for worst-case signal parameters and dedicated upper limits for generic ~0 spindown signals, such as those expected from boson condensates around black holes.

description: We study the transport through a quantum dot, in the Kondo Coulomb blockade valley, embedded in a mesoscopic device with finite wires. The quantization of states in the circuit that hosts the quantum dot gives rise to finite size effects. These effects make the conductance sensitive to the ratio of the Kondo screening length to the wires length and provide a way of measuring the Kondo cloud. We present results obtained with the numerical renormalization group for a wide range of physically accessible parameters.

description: Recent studies proved that deep learning approaches achieve remarkable results on face detection task. On the other hand, the advances gave rise to a new problem associated with the security of the deep convolutional neural network models unveiling potential risks of DCNNs based applications. Even minor input changes in the digital domain can result in the network being fooled. It was shown then that some deep learning-based face detectors are prone to adversarial attacks not only in a digital domain but also in the real world. In the paper, we investigate the security of the well-known cascade CNN face detection system - MTCNN and introduce an easily reproducible and a robust way to attack it. We propose different face attributes printed on an ordinary white and black printer and attached either to the medical face mask or to the face directly. Our approach is capable of breaking the MTCNN detector in a real-world scenario.

description: Epidemics tend to have a debilitating influence on the lives of directly afflicted families. However, the presence of an epidemic can also change the behaviour and outcomes of those not directly affected. This paper makes use of a short, sharp, unexpected epidemic to examine the behavioural response of the public to a sudden shift in the perceived risk to one’s health and mortality. Our analysis finds that unafflicted school students change their behaviour substantially, affecting important life outcomes. In particular, we find that between 1.9 and 4.7 fewer students, out of a typical cohort of 47 pupils, sit their school leaving examination for every additional 10 cases of severe Dengue per 10 000 inhabitants in a municipality. We rule out several possible mechanisms, leaving an increase in the salience of the disease’s risks as a plausible explanation for our findings.

description: This paper examines the impact of the introduction of the value-added tax on inequality and government revenues using newly released macro data. We present both conventional country fixed effect regressions and instrumental variable analyses, where VAT adoption is instrumented using the previous values of neighbouring countries’ VAT systems as an instrument. The results reveal – in contrast to earlier work – that the revenue consequences of the VAT have not been positive. The results indicate that income-based inequality has increased due to the VAT adoption, whereas consumption inequality has remained unaffected.
