description: We report on the realisation of an original SAGFET technology, presenting d.c. and r.f. measurements on discrete devices as a demonstration of the validity of said technology. Even though at an initial stage, the low-noise, control and power devices, simultaneously fabricated on the same wafer, are comparable with the more mature recessed-gate technology, yielding NF better than 2 dB and Pout better than 500 mW/mm at 12 GHz. As an example of the potentiality of this technology a prototype Tx/Rx chip is also presented.

description: Any evolution described by a completely positive trace-preserving linear map can be imagined as arising from the interaction of the evolving system with an initially uncorrelated ancilla. The interaction is given by a joint unitary operator, acting on the system and the ancilla. Here we study the properties such a unitary operator must have in order to force the choice of a physical- that is, positive-state for the ancilla if the end result is to be a physical-that is, completely positive-evolution of the system.

description: Multifunction properties of GaAs and other III-V semi-insulating crystals could be expanded by the artificial decreasing of their electric response symmetry that could be transformed from piezo- into a pyroelectric class. Artificial pyroelectricity of III-V type semiconductors forms a basis for one-crystal pyroelectric sensor. The voltage sensitivity of GaAs (111)-cut is the similar to PZT pyroelectric ceramics, so GaAs wafer could be used as a thermal-to-electric transducer in a new microelectronic device named pyrotransistor. The last is uncooling far infrared (IR) detector based on MESFET technology.

description: We present electronic and magnetic properties of a honeycomb compound In$_{3}$Cu$_{2}$VO$_{9}$ in this paper. We find that the parent phase is a charge transfer insulator with an energy gap of about 1.5 eV. Singly occupied d$_{3z^{2}-r^{2}}$ electrons of copper ions contribute an $S$ = 1/2 spin, while vanadium ions show nonmagnetism. Oxygen 2$p$ orbitals hybridizing with a small fraction of Cu 3$d$ orbitals dominate the density of states near $E_{F}$. The planar nearest-neighbor, next-nearest-neighbor and interplane superexchange couplings of Cu spins are $J_{1}$ $\approx$ 16.2 meV, $J_{2}$ $\approx$ 0.3 meV and $J_{z}$ $\approx$ 1.2 meV, suggesting a low-dimensional antiferromagnet \cite{Sondhi10}. We propose that the magnetic frustration along the c-axis leads to a quantum spin disorder in In$_{3}$Cu$_{2}$VO$_{9}$, in accordance with the recent experiments. {abstract}

description: On the basis of two-dimensional numerical simulation the formation, evolution and kinetics of spatial dissipative structures (DS) under breakdown of GaAs n-i-n structure are studied. It is found, that at some critical length of the n-GaAs layer the instability of spatial distribution of the current along contacts results in the formation of spatial periodic structures as multiple current filaments. With current increase the spatial period of DS decreases down to some minimum value. It is revealed that physically DS formation is the result of a distinction between a small spatial parameter of instability (due to avalanche-injection modulation of i-region conductivity) and a large spatial parameter of current damping (due to current spreading in the lengthy n-contact region).

description: This paper presents a simple design technique for differential amplifiers working at frequencies above few GHz, that allows the application of well-known low frequency techniques to microwave circuitry. It is based on the parametrization of the characteristic functions of a differential pair -CMRR and differential gains - in terms of only three design variables: drain resistor Rd gate width Wl and normalized bias current i=Id/Idss A 0.5-6 GHz power divider providing both in-phase power division and gain has been designed using the proposed technique. An amplitude balance <0.2 dB and a phase balance <3° have been measured. The chip has been designed using the 0.5 um, F20 process of GEC-Marconi.

A nonlinear circuit model for lithium-ion batteries
Creators: name: Ren, Shengru
Publisher: name: University of British Columbia
Year: 2014

description: A lithium ion battery model is required for proper design of battery powered systems such as marine applications. The various existing models lack of the nonlinear aspect of the batteries being studied, suffer from high complexity and are not quite suitable for system level simulation. Therefore the scope of this thesis is to produce a battery model capable of capturing the nonlinearity of the battery for system level design. The Randle circuit model is selected as the base model to build upon and the electrochemical impedance spectroscopy is chosen as the fundamental test method for extracting the model parameters. The nonlinearity is accounted for by defining the equivalent circuit model elements’ parameters functions of the state of charge. Since lithium-ion batteries are prone to be affected by the changes in temperature, all the experiments are done under controlled temperature. The proposed model is a modified Randle circuit model in time domain implemented in MatLAB/SIMULINK. The model’s validity is verified using test data. It is concluded that this final version of model proposed in this thesis can be used directly in system level simulation while offering reasonable accuracy. However the proposed model does suffer from its dependency on the cell chemistry, which will limit its applications.

description: Tidal effects have long ago locked the Moon in synchronous rotation with the Earth and progressively increase the Earth-Moon distance. This "tidal acceleration" hinges on dissipation. Binaries containing black holes may also be tidally accelerated, dissipation being caused by the event horizon - a flexible, viscous one-way membrane. In fact, this process is known for many years under a different guise: superradiance. In General Relativity, tidal acceleration is obscured by gravitational-wave emission. However, when coupling to light scalar degrees of freedom is allowed, an induced dipole moment produces a "polarization acceleration", which might be orders of magnitude stronger than tidal quadrupolar effects. Consequences for optical and gravitational-wave observations are intriguing and it is not impossible that imprints of such mechanism have already been observed.

Patterns of neutral diversity under general models of selective sweeps

Subjects: subject: Populations and Evolution (q-bio.PE)

description: Two major sources of stochasticity in the dynamics of neutral alleles result from resampling of finite populations (genetic drift) and the random genetic background of nearby selected alleles on which the neutral alleles are found (linked selection). There is now good evidence that linked selection plays an important role in shaping polymorphism levels in a number of species. One of the best investigated models of linked selection is the recurrent full sweep model, in which newly arisen selected alleles fix rapidly. However, the bulk of selected alleles that sweep into the population may not be destined for rapid fixation. Here we develop a general model of recurrent selective sweeps in a coalescent framework, one that generalizes the recurrent full sweep model to the case where selected alleles do not sweep to fixation. We show that in a large population, only the initial rapid increase of a selected allele affects the genealogy at partially linked sites, which under fairly general assumptions are unaffected by the subsequent fate of the selected allele. We also apply the theory to a simple model to investigate the impact of recurrent partial sweeps on levels of neutral diversity, and find that for a given reduction in diversity, the impact of recurrent partial sweeps on the frequency spectrum at neutral sites is determined primarily by the frequencies achieved by the selected alleles. Consequently, recurrent sweeps of selected alleles to low frequencies can have a profound effect on levels of diversity but can leave the frequency spectrum relatively unperturbed. In fact, the limiting coalescent model under a high rate of sweeps to low frequency is identical to the standard neutral model. The general model of selective sweeps we describe goes some way towards providing a more flexible framework to describe genomic patterns of diversity than is currently available.

description: The concept of natural pseudo-distance has proven to be a powerful tool for measuring the dissimilarity between shape properties of topological spaces, modeled as continuous real-valued functions defined on the spaces themselves. Roughly speaking, the natural pseudo-distance is defined as the infimum of the change of the functions' values, when moving from one space to the other through homeomorphisms, if possible. In this paper, we prove the first available result about the existence of optimal homeomorphisms between
closed curves, i.e. inducing a change of the function that equals the natural pseudo-distance.

description: An intriguing hypothesis is that gravity may be non-perturbatively renormalizable via the notion of asymptotic safety. We show that the Higgs sector of the SM minimally coupled to asymptotically safe gravity can generate the observed near scale-invariant spectrum of the Cosmic Microwave Background through the curvaton mechanism. The resulting primordial power spectrum places an upper bound on the Higgs mass, which for finely tuned values of the curvaton parameters, is compatible with the recently released Large Hadron Collider data.

Steam pre-treatment and leaching for the production of high quality oil palm residue pellets
Creators: name: Lam, Pak Yiu
Publisher: name: University of British Columbia
Year: 2013

description: It is estimated that about 26 million metric tons of oil palm oil residues are produced annually in Malaysia. The oil palm residues contain high ash content, high alkali metals and low lignin content. Ash and alkali metals lead to slagging in a combustion reactor and fouling of surfaces in convective tubes of heat exchangers. Low lignin content leads to disintegration of pellets during pellet handling and storage. This research thesis investigated the pelletization performance and the ash reduction on Empty Fruit Bunches (EFB) and Palm Kernel Shell (PKS) of oil palm residues by two different pre-treatment processes: steam explosion and water leaching. Steam explosion for increasing binding ability was performed by reacting EFB/PKS with saturated steam ranging from 120 to 220℃ for 5 minutes in a batch reactor. Water leaching for reducing the ash and alkali metals of EFB and PKS was investigated by immersing the samples in water from 25 to 55℃. The immersion time ranged from instantaneous to 240 minutes. Single pellets were made from water treated and steam treated samples. A significant ash reduction from 5.47 to 2.47 % was found for the EFB pellet due to water leaching. A slight reduction of pellet’s porosity and a significant reduction in ash content suggested that water leaching may be used to improve the quality of EFB as a biofuel. On the other hand, pre-treatment processes were not necessary for PKS, considering low binding ability and no ash reduction after pre-treatments. Kinetic models of EFB and PKS leaching were developed. A mass balance of cross flow process was investigated for evaluating the number of stages for a continuous leaching system of EFB and PKS. The techno-economic analysis showed that the additional leaching process costs $25.75 per tonne in a pellet making line.

description: Traditionally stellar radiation has been the only heat source considered capable of determining global climate on long timescales. Here we show that terrestrial exoplanets orbiting low-mass stars may be tidally heated at high enough levels to induce a runaway greenhouse for a long enough duration for all the hydrogen to escape. Without hydrogen, the planet no longer has water and cannot support life. We call these planets "Tidal Venuses," and the phenomenon a "tidal greenhouse." Tidal effects also circularize the orbit, which decreases tidal heating. Hence, some planets may form with large eccentricity, with its accompanying large tidal heating, and lose their water, but eventually settle into nearly circular orbits (i.e. with negligible tidal heating) in the habitable zone (HZ). However, these planets are not habitable as past tidal heating desiccated them, and hence should not be ranked highly for detailed follow-up observations aimed at detecting biosignatures. Planets orbiting stars with masses <0.3 solar masses may be in danger of desiccation via tidal heating. We apply these concepts to Gl 667C c, a ~4.5 Earth-mass planet orbiting a 0.3 solar mass star at 0.12 AU. We find that it probably did not lose its water via tidal heating as orbital stability is unlikely for the high eccentricities required for the tidal greenhouse. As the inner edge of the HZ is defined by the onset of a runaway or moist greenhouse powered by radiation, our results represent a fundamental revision to the HZ for non-circular orbits. In the appendices we review a) the moist and runaway greenhouses, b) hydrogen escape, c) stellar mass-radius and mass-luminosity relations, d) terrestrial planet mass-radius relations, and e) linear tidal theories.

description: Nel 1952 Jan Olof Tjäder riusciva finalmente a decifrare la cosiddetta misteriosa scrittura grande che caratterizza la prima riga di quattro papiri ravennati contenenti protocolli dei gesta municipalia (504-625 d. C.) e a individuarne la base grafica nella corsiva romana antica. Questo permetteva quindi al Tjäder di dimostrare che l’antica scrittura comune romana non era sopravvissuta, dopo il IV secolo, solo nelle litterae caelestes riservate ai documenti imperiali (cfr. Th.9.19.3, 367 d. C.), ma che ad esse si affiancavano anche le scritture iniziali di alcuni papiri egiziani contenenti processi verbali d’udienza e, appunto, quella dei protocolli dei gesta ravennati.
Il presente contributo si propone dunque una verifica della teoria del Tjäder circa il ruolo che la misteriosa scrittura grande ravennate ha avuto nella storia della scrittura latina, soprattutto alla luce delle più recenti edizioni che hanno reso accessibile un sempre maggior numero di fonti per i secoli III-VII. Quindi si è tentato di riconnettere il dato grafico che emerge dai gesta ravennati ad un quadro storico-istituzionale più ampio, in particolare attraverso il confronto tra le fonti documentarie, le fonti legislative (relativamente a quegli interventi normativi che interessano direttamente la scrittura dei documenti pubblici) e la storiografia di carattere paleografico.

description: Nach der Tumornephrektomie stellt sich die grundlegende Frage nach der Prognose hinsichtlich einer Metastasierung. In der vorgestellten Untersuchung verglichen wir die HLA Klasse-I und -II Merkmale von 100 Nierenzellkarzinompatienten (NZK) sowie der 24 davon metastasierten NZK-Patienten mit den Merkmalen einer Kontrollgruppe von 157 Personen. Statistische Analysen zeigten keine signifikanten Unterschiede hinsichtlich der HLA Klasse-I Merkmale für NZK-Patienten. Dahingegen konnten wir eine erhöhte Frequenz für die HLA Klasse-II Merkmale HLA-DRB1*01 und -DQB1*05 bestimmen. Unter den 24 metastasierten NZK-Patienten war die erhöhte Frequenz von HLA-DQB1*05 erneut nachzuvollziehen. In dieser Gruppe konnten zusätzlich HLA-A*31 und -Cw*04 gehäuft nachgewiesen werden. HLA-DRB1*01 war unter den metastasierten NZK-Patienten nicht mehr nachzuweisen. Die Ergebnisse wurden durch Analyse von HLA-Merkmalkombinationen überprüft und bestätigt. HLA-A*31, -A*32, -B*35, -Cw*04, -Cw*12, -DRB1*01, -DRB1*15, -DQB1*05 und -DQB1*06 sind zur Erstellung von individuellen Risikoprofilen bei Patienten nach Tumornephrektomie geeignet.
description: The most fundamental question which arises after tumornephrectomy is whether or not metastases will develop. In our investigations, we analysed HLA- class I and II alleles 2 detected in the 100 renal cell carcinoma patients (rcc) and those detected in the 24 metastatic rcc patients and compared them with individuals in the control group. Statistic analyses (c ²-test; Fisher’s-exact test) could not detect any significant deviation of HLA-class-I-alleles frequencies in the group of 100 rcc patients when compared with the control group. We, however, detected increases in HLA-class-II-alleles frequencies in HLA-DRB1*01 and -DQB1*05. 24 patients developed metastases. In this group we also noted increases in HLA-DQB1*05 frequency. HLA-A*31 and -Cw*04 were detected as increases too. Among mestastatic rcc patients an evident increase in HLA-DRB1*01 could no longer be detected as it initially was among the 100 rcc patients. An increase in DQBI*05 was detected in mestastatic rcc patients as well. We rechecked our results by analysing allelic combinations of two and three alleles. We also detected supplementary prognostic alleles. HLA-A*31, -A*32, -B*35, -Cw*04, -Cw*12, DRB1*01, -DRB1*15, -DQB1*05 and -DQB1*06 are alleles with prognostic classification factors for renal cell carcinomas and are useful for establishing a risk profile.

description: A general canonical formalism for discrete systems is developed which can handle varying phase space dimensions and constraints. The central ingredient is Hamilton's principal function which generates canonical time evolution and ensures that the canonical formalism reproduces the dynamics of the covariant formulation following directly from the action. We apply this formalism to simplicial gravity and (Euclidean) Regge calculus, in particular. A discrete forward/backward evolution is realized by gluing/removing single simplices step by step to/from a bulk triangulation and amounts to Pachner moves in the triangulated hypersurfaces. As a result, the hypersurfaces evolve in a discrete `multi-fingered' time through the full Regge solution. Pachner moves are an elementary and ergodic class of homeomorphisms and generically change the number of variables, but can be implemented as canonical transformations on naturally extended phase spaces. Some moves introduce a priori free data which, however, may become fixed a posteriori by constraints arising in subsequent moves. The end result is a general and fully consistent formulation of canonical Regge calculus, thereby removing a longstanding obstacle in connecting covariant simplicial gravity models to canonical frameworks. The present scheme is, therefore, interesting in view of many approaches to quantum gravity, but may also prove useful for numerical implementations.

description: In assessing the risks associated with climate change, ‘tail risks’ (low-probability extreme events) often play a much larger role than their probability alone might indicate. There are three main reasons for this: the linear relationship between sensitivity and warming; the convexity of the damage function; and the concavity of the utility function. Ignoring the upper tail of the distribution of possible outcomes will result in serious underestimates of the social cost of carbon dioxide (CO2) emissions and of the socially optimal price for emissions.

description: In this paper, we use the China Health and Nutrition Survey (CHNS) panel data to analyse the impact of drinking water on off-farm labour supply. A two-stage least squares (2SLS) multivariate Tobit regression model with random effects was applied. We find that impacts of drinking water conditions on off-farm labour supply may be greater for women than men but depends on the specific family role or family structure. A strong within-gender effect exists in households. For example, daughters are not sensitive to water access nor water quality, but householder’s spouses are sensitive to water access, and daughters-in-law are sensitive to water quality. Our findings suggest that infrastructure development in improved access to safe water has contributed positively to reductions in traditional gender biases, evening the playing field between daughters, daughters-in-law, mothers and mothers-in-law. We also find that water the infrastructure program may actually encourage off-farm labour mobility, reducing the supply of agricultural labour and the share of household labour on the farm. Thus, a broader approach to water policy should also include public investment in achieving greater labour efficiency and productivity.

description: In this paper, we study the homology of the coloring complex and the cyclic coloring complex of a complete $k$-uniform hypergraph. We show that the coloring complex of a complete $k$-uniform hypergraph is shellable, and we determine the rank of its unique nontrivial homology group in terms of its chromatic polynomial. We also show that the dimension of the $(n-k-1)^{st}$ homology group of the cyclic coloring complex of a complete $k$-uniform hypergraph is given by a binomial coefficient. Further, we discuss a complex whose $r$-faces consist of all ordered set partitions $[B_1, \hdots, B_{r+2}]$ where none of the $B_i$ contain a hyperedge of the complete $k$-uniform hypergraph $H$ and where $1 \in B_1$. It is shown that the dimensions of the homology groups of this complex are given by binomial coefficients. As a consequence, this result gives the dimensions of the multilinear parts of the cyclic homology groups of $\C[x_1, \hdots, x_n]/ \{x_{i_1} \hdots x_{i_k} \mid i_{1} \hdots i_{k}$ is a hyperedge of $H \}$.

Since it has been proved that these Maher measures can also be expressed in terms of logarithms and $_5F_4$-hypergeometric series, we obtain several new hypergeometric evaluations and transformations from these results.
Judicial reforms in transition:
Legacy of the past and judicial institutionalization in post-communist countries.

description: The breakdown of authoritarian regimes in Eastern Europe and the incremental democratisation of such regimes is surely one of the most crucial events in the last two decades. In these contexts, the functioning of justice systems has become, more and more, one of the key aspects of the transition process. 
In this context, the article analyses the process of judicial reform in Slovenia, Croatia and Serbia. The article aims to explore how theoretical approaches developed by comparative judicial studies scholars fare against the evidence from the democratising process of the judiciary in such countries. Then, particular attention will be focused upon the level of institutionalization of the judicial systems, trying to explain why judicial systems in these countries continue to be poorly institutionalized.

description: The Lagrangian equations of motion for massive spinning test particles (tops) moving on a gravitational background using General Relativity are presented. The paths followed by tops are nongeodesic. An exact solution for the motion of tops on a Schwarzschild background which allows for superluminal propagation of tops is studied. It is shown that the solution becomes relevant for particles with small masses, such as neutrinos. This general result is used to calculate the necessary condition to produce superluminal motion in part of the trajectory of a small mass particle in a weak gravitational field. The condition for superluminal motion establishes a relation between the mass, energy and total angular momentum of the particle.

description: Der Arbeit liegt die Frage zugrunde, welche Grundsätze der Wirtschaftspolitik zur Beurteilung der Agrarpolitik herangezogen werden können. Durch die Veränderungen in der agrarpolitischen Wirklichkeit werden hierzu verstärkt andere als der vorherrschende wohlfahrtsökonomische Ansatz notwendig. Vorgestellt werden der Ansatz der Theorie der quantitativen Wirtschaftspolitik und ein spezieller Ansatz aus dem Bereich des Public Choice, die Verfassungsökonomik. Anhand der Tinbergen-Regel wird beispielhaft eine Analyse der Politik für den Ökolandbau durchgeführt. Auf Anwendungsmöglichkeiten der Konsensregel wird hingewiesen.
The targum (1870:Feb.)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1870

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: This paper proposes an innovative framework to detect financial crises, pinpoint the end of a crisis and predict future developments in stock markets. This proposal is based on a latent Markov model and allows for a specific focus on conditional mean returns. By analyzing weekly changes in the U.S. stock market indexes over a period of 20 years, this study obtains an accurate detection of stable and turmoil periods and a probabilistic measure of switching between different stock market conditions. The results contribute to the discussion of the capabilities of latent Markov models and give financial operators some appealing investment strategies.
Probabilistic wind speed forecasting in Hungary

description: Prediction of various weather quantities is mostly based on deterministic numerical weather forecasting models. Multiple runs of these models with different initial conditions result ensembles of forecasts which are applied for estimating the distribution of future weather quantities. However, the ensembles are usually under-dispersive and uncalibrated, so post-processing is required. In the present work Bayesian Model Averaging (BMA) is applied for calibrating ensembles of wind speed forecasts produced by the operational Limited Area Model Ensemble Prediction System of the Hungarian Meteorological Service (HMS). We describe two possible BMA models for wind speed data of the HMS and show that BMA post-processing significantly improves the calibration and precision of forecasts.

Bargaining with Noisy Communication

Subjects: SECS-P/01 Economia politica

description: In this paper we show that in a bargaining situation the seller may not necessarily want to fully exploit communication possibilities. In the standard two-period bargaining model with one-sided incomplete information, the seller, who owns an indivisible good, makes offers which the buyer can either accept or reject. We ask whether the seller can profit from manipulating the communication mechanism by sending offers that reach the buyer with probability less than one (noisy communication). Noisy communication is a way to improve the seller's second period beliefs about the buyer's willingness to pay for the good and is therefore a way to "buy" commitment. We study the case of a discrete distribution of buyer's types and show that there exist equilibria with noisy communication when there are at least three different types of buyers.

description: The paper studies the rate of convergence of the weak Euler approximation for solutions to possibly completely degenerate SDEs driven by Levy processes, with Hoelder-continuous coefficients. It investigates the dependence of the rate on the regularity of coefficients and driving processes. In addition, the rate robustness to the approximation of the increments of the driving process is studied and approximate Euler scheme considered. A rate of convergence is derived for an approximate jump-adapted scheme as well.

description: Sfp-Typ 4‘-Phosphopantetheinyltransferasen (PPTasen) aktivieren in filamentösen Pilzen Polyketidsynthasen (PKS), nichtribosomale Peptidsynthasen (NRPS) und die α-amino-Adipatreduktase. PPTase-defiziente Mutanten (∆Cgppt1) des Maispathogens Colletotrichum graminicola wurden erzeugt und phänotypisch charakterisiert. ∆Cgppt1-Isolate waren auxotroph für Lysin, hypersensitiv gegenüber reaktiven Sauerstoffspezies und nicht in der Lage, auf Medien mit komplexierten Eisenionen zu wachsen bzw. Siderophore oder Polyketide zu synthetisieren. In differentiellen Metabolitanalysen von Wildtyp und ∆Cgppt1 konnten neben zehn bekannten Metaboliten fünf bisher unbe-kannte Polyketide isoliert und strukturell charakterisiert werden. Untersuchungen zum Infektionsverlauf zeigten, dass die in geringer Anzahl gebildeten ∆Cgppt1-Appressorien auf intakten Mais- und Zwiebelepidermen lysierten, während verletzte Maisblätter symptomlos besiedelt wurden, ohne dass es dabei zur Entstehung von Konidien kam.

description: In questo lavoro si esamina la recente letteratura di analisi dell’efficienza produttiva e di costo attraverso la stima di frontiere di costo e di produzione nel settore del trasporto pubblico locale. Nell’ultima parte dell’articolo presentiamo uno studio sul settore del trasporto pubblico locale in Emilia-Romagna. La funzione specificata è di costo variabile. Il modello, stimato con dati panel, è del tipo uniequazionale con fixed effects. I risultati della stima indicano la presenza di ingenti economie di scala, sia di breve che di lungo periodo, secondo un andamento che decresce al crescere della dimensione aziendale. La stima degli indicatori di inefficienza rivela l'esistenza di significativi spazi di aggiustamento delle prestazioni soprattutto per le imprese di maggiori dimensioni.
Process Innovation and the Persistence of Monopoly with Labour-Managed Firms

Subjects: SECS-P/01 Economia politica

description: The issue of the persistence of monopoly when at least one labour-managed firm takes part in an auction for a cost-reducing innovation is tackled in this paper. It is shown that (i) when the incumbent is a profit-maximizing firm while the entrant is a labour-managed firm, monopoly persists; (ii) when both firms are labour-managed, monopoly persists only if the technology initially employed by the incumbent is highly ine¢cient as compared to the new one; and, finally, (iii) when the incumbent is labour-managed while the outsider is a profit seeking agent, then entry always occurs and monopoly changes hands.

Strategic Delegation and the Shape of Market Competition

Publisher: name: Alma Mater Studiorum - Università di Bologna

Subjects: SECS-P/01 Economia politica

description: Which shape market competition is likely to exhibit? This question is addressed in the present paper, where firms can choose whether to act as quantity or price setters, whether to move early or delay as long as possible at the market stage and finally whether to be entrepreneurial or managerial. Moreover, firms can endogenously determine the sequence of such decisions. It is shown that in correspondence of the (unique) subgame perfect equilibrium of the game, all firms first decide to delay, then to act as Cournot competitors, and finally stockholders decide to delegate control to managers. Hence, sequential play between either managerial or entrepreneurial firms, as well as simultaneous play between entrepreneurial firms are ruled out.
