description: During the last decade, citizens have put a lot of attention to agricultural policy dimensions like multifunctionality, animal welfare, food safety, food security and environmental issues. Based on quantitative survey data set (n=1,623), this research examines Finnish citizens ́ concerns about various dimensions of agricultural policy. Principal component analysis resulted in a solution of four components. It seems that most worries by citizens relate to policy dimensions, which may cause personal risks in a long-term and which lie beyond personal control. Concerns that are more distant were not very worrying.

subject: Andalusia

description: This contribution analyzes the likely impacts of the new CAP reform on different olive farming systems in Andalusia, Spain. It uses a Positive Mathematical Programming model calibrated with the neutral procedure. The model compares the situation of the average olive farm in the base year with its position in a simulated year using two policy scenarios. Results indicate inter alia that the new distribution rules of aids don’t incentive the adoption of integrated and organic farming. Alternatively, implementing green payment scheme would better redistribute public support from less to more environmentally-friendly olive farming practices, enhancing the CAP aids legitimacy.

description: Second magnetization peak (SMP) in hole-doped cuprates and iron pnictide superconductors has been widely explored. However, similar feature in the family of electron-doped cuprates is not common. Here, we report the vortex dynamics study in the single crystal of an electron-doped cuprate Pr$_{0.87}$LaCe$_{0.13}$CuO$_4$ superconductor using dc magnetization measurements. A SMP feature in the isothermal $M(H)$ was observed for $H$$\parallel$$ab$-planes. On the other hand, no such feature was observed for $H$$\parallel$$c$-axis in the crystal. Using magnetic relaxation data, a detailed analysis of activation pinning energy via collective creep theory suggests an elastic to plastic creep crossover across the SMP. Moreover, for $H$$\parallel$$ab$, a peak in the temperature dependence of critical current density is also observed near 7 K, which is likely be related to a dimensional crossover (3D-2D) associated to the emergence of Josephson vortices at low temperatures. The anisotropy parameter obtained $γ$ $\approx$ 8-11 indicates the 3D nature of vortex lattice mainly for $H$$\parallel$$c$-axis. The $H$-$T$ phase diagrams for $H$$\parallel$$c$ and $H$$\parallel$$ab$ are presented.

Detecting cold H2 globules in the outer Galactic disc by microlensing towards the Maffei 1 elliptical

Subjects: subject: Astrophysics (astro-ph)

description: A serious candidate for dark matter in spiral galaxies are cold molecular hydrogen globules with a condensed central core and a disc-like space distribution probably similar to that of neutral hydrogen. This paper shows that the H_2 cores are sufficiently compact and massive to be detected by microlensing in the outer Galactic disc and that the Maffei 1 elliptical galaxy, at a distance of 3 Mpc and Galactic latitude b=-0.6 deg, offers an ideal target for such an experiment. The microlensing optical depth of H_2 cores along the line of sight to this galaxy is estimated to tau~0.7x10^(-6) if most of the dark mass in the Milky Way resides in such cores, and the typical event timescale to ~< 1 day. Detection rates are computed both in the classical and pixel lensing approaches in the I- and K-bands, and for a representative selection of existing observing facilities. In the more efficient pixel lensing case, two 10-hour observing runs, separated in time by at least several days, should yield of order 10 positive detections at the 5-sigma level using ground-based 8m-class telescopes in the K-band or the Hubble Space Telescope ACS camera in the I-band, and the corresponding fraction of events with timescale measurable to an accuracy better than 50% amounts to about 9% and 4% respectively for these observing alternatives.

description: We propose a reinforcement learning (RL) scheme for feedback quantum control within the quan-tum approximate optimization algorithm (QAOA). QAOA requires a variational minimization for states constructed by applying a sequence of unitary operators, depending on parameters living ina highly dimensional space. We reformulate such a minimum search as a learning task, where a RL agent chooses the control parameters for the unitaries, given partial information on the system. We show that our RL scheme finds a policy converging to the optimal adiabatic solution for QAOA found by Mbeng et al. arXiv:1906.08948 for the translationally invariant quantum Ising chain. In presence of disorder, we show that our RL scheme allows the training part to be performed on small samples, and transferred successfully on larger systems.

description: Multiple-input multiple-output (MIMO) systems are usually present in process systems engineering. Due to the interaction among the variables and loops in the MIMO system, designing efficient control systems for both servo and regulatory scenarios remains a challenging task. The literature reports the use of several techniques mainly based on classical approaches, such as the proportional-integral-derivative (PID) controller, for single-input single-output (SISO) systems control. Furthermore, control system design approaches based on derivatives and integrals of non-integer order, also known as fractional control or fractional order (FO) control, are frequently used for SISO systems control. A natural consequence, already reported in the literature, is the application of these techniques to MIMO systems to address some inherent issues. Therefore, this work discusses the state-of-the-art of fractional control applied to MIMO systems. It outlines different types of applications, fractional controllers, controller tuning rules, experimental validation, software, and appropriate loop decoupling techniques, leading to literature gaps and research opportunities. The span of publications explored in this survey ranged from the years 1997 to 2019.
Artefacts of circumpolar cartography in radio pulsar polarization
Creators: name: Dyks, J.
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Single pulse data on radio pulsar polarization are traditionally presented in the form of two-dimentional greyscale patterns with the pulse longitude and polarization angle (PA) on the horizontal and vertical axis, respectively. Such diagrams reveal several enigmatic polarization effects: 1) bifurcations and loops of PA curve under central pulse components, 2) vertical spread of flux at all PA values, 3) exchange of power content between PA tracks of two orthogonal polarization modes (OPMs), and 4) peripherically-flat PA swings that span more than 180 degrees. It is shown that all these phenomena result from passage of observed polarization state near the pure-V pole of Poincare sphere. Much of their complexity results from cartographic transformation from Poincare sphere to the longitude-PA plane. An odd number of near-pole passage produces apparent replacement of OPMs power in the profile wings, although the same amount of flux keeps staying in each modal patch on the Poincare sphere. The fitting of pulsar PA curves should therefore allow for transitions between the primary (strong) and secondary (weak) PA track. The Stokes-space (or Poincare-sphere) representation of pulsar polarization data contains crucial polarization information and needs to accompany the traditional viewing if the published figures are to be fully useful for interpretation.

description: In the last hundred years, great changes have taken place in the farming systems all over the world. They were economically driven and beneficial but they also lead to a range of negative side effects. At the same time consumer awareness regarding food quality and safety grew, together with rising willingness for nature conservation and rural identity preservation. The paper focuses on the High Nature Value (HNV) farming as an environmental solution for long-term conservation and protection of biodiversity and its broader impact on the economic and social sustainability of agriculture and rural development at regional level.

description: Many key problems in machine learning and data science are routinely modeled as optimization problems and solved via optimization algorithms. With the increase of the volume of data and the size and complexity of the statistical models used to formulate these often ill-conditioned optimization tasks, there is a need for new efficient algorithms able to cope with these challenges. In this thesis, we deal with each of these sources of difficulty in a different way. To efficiently address the big data issue, we develop new methods which in each iteration examine a small random subset of the training data only. To handle the big model issue, we develop methods which in each iteration update a random subset of the model parameters only. Finally, to deal with ill-conditioned problems, we devise methods that incorporate either higher-order information or Nesterov's acceleration/momentum. In all cases, randomness is viewed as a powerful algorithmic tool that we tune, both in theory and in experiments, to achieve the best results. Our algorithms have their primary application in training supervised machine learning models via regularized empirical risk minimization, which is the dominant paradigm for training such models. However, due to their generality, our methods can be applied in many other fields, including but not limited to data science, engineering, scientific computing, and statistics.

description: This poster paper aims to investigate the consumers’ preferences and willingness to pay for different quality strategies associated with the designations Prosciutto di Parma PDO. After a qualitative analysis, an on-line choice experiment was conducted on a sample of 250 Italian consumers. A multinomial logit model was tested to assess the relative importance of quality attributes. The results show that price, a “high quality” PDO label and the ageing period are the most important attributes for consumers. These findings provide Consortium members with an important food for thought for the development of future strategies for the Designation of Origin.

description: This paper tackles several issues under-studied concerning agri-environmental schemes (AES), namely requirements related to ecological focus areas (EFA) and collective participation. For this purpose, choice experiment was used to assess farmers’ preferences towards AES in olive growing of Southern Spain. A high heterogeneity was found, being identified four different classes of farmers, from potential participants to intermediate and non-participants. Almost half of the farmers would implement EFA at low monetary incentives (€8-9/ha per 1%-EFA) and the rest would do it at moderate to high monetary incentives (€41-151/ha per 1%-EFA). Most of farmers would not participate collectively with an up-to-30% bonus.

description: Half-Heusler compounds usually exhibit relatively higher lattice thermal conductivity that is undesirable for thermoelectric applications. Here we demonstrate by first-principles calculations and Boltzmann transport theory that the BiBaK system is an exception, which has rather low thermal conductivity as evidenced by very small phonon group velocity and relaxation time. Detailed analysis indicates that the heavy Bi and Ba atoms form a cage-like structure, inside which the light K atom rattles with larger atomic displacement parameters. In combination with its good electronic transport properties, the BiBaK shows a maximum n-type ZT value of 1.9 at 900 K, which outperforms most half-Heusler thermoelectric materials.

description: The present paper describes the role of organic farming measures in the safeguard of the High Nature Value in Tuscany. Using National Census of Agriculture data (2010) the probability of program enrolment has been computed, through a Probit model. After, a Propensity Score Matching approach has been implemented, to verify what would have happened if treated farms would not have participated to the program. Hence, a control group with similar characteristics as the treated one has been built. Finally, the Average Treatment on the Treated has been computed, revealing organic farming measures have not statistical relevance in enhancing biodiversity.

description: Rural Development policies and measures has since long been a primary aim for public policies in the EU and Greece, such that is the LEADER programme. The assessment of the performance of this policy for supporting an integrated development in a rural region in Greece is the main objective of the current study. Specifically, it is aimed to assess potential economy- wide impacts in the regional economy and capture impacts on the local output, employment and household income, employing regional Input-Output modeling. Results indicate that important impacts can be induced in the regional economy for specific sectors, despite the overall poor performance of the programme for the whole economy. The programme's performance is highly affected by the small budget and its distribution to the economy's sectors'.
Insight into soil microbial ecology through the development and application of serial analysis of ribosomal sequence tags (SARST) and a community-specific microarray
Creators: name: Neufeld, Josh David
Publisher: name: University of British Columbia
Year: 2009

description: In order to overcome technical hurdles hindering progress in soil microbial ecology, this project involved the development and application of a molecular assay for measuring microbial community composition and diversity. Serial analysis of ribosomal sequence tags (SARST) generates libraries of a short and variable portion of the 16S rRNA gene. A series of enzymatic reactions amplifies and ligates ribosomal sequence tags (RSTs) into concatemers that are cloned and sequenced. On average, 5-10 RSTs were obtained from multiple phylotypes with each sequencing reaction. SARST was initially tested on: 1) activated sludge, 2) boreal forest soil, 3) a mixture of pure cultures and 4) duplicate libraries from an arctic tundra soil sample. SARST was also used to study microbial communities within soils sampled from Canada and Spain. Bacterial diversity of geographically distinct locations was characterized for Canadian arctic tundra and boreal forest soil biomes. Composite samples taken from arctic tundra demonstrated significantly higher estimates of bacterial diversity than boreal forest soils. Also, despite climate differences, the overall phylotype compositions of boreal forest soil libraries did not cluster distinctly from tundra samples. As a result of large RST libraries, individual phylotypes were identified that were associated with all soil libraries and others were unique to specific samples. These sequences represent potentially cosmopolitan and endemic distributions of these organisms. Several soils in the Basque Country of Spain are contaminated with high concentrations of hexachlorocyclohexane (HCH). However, the impact of HCH on soil bacterial community structure is not well understood. SARST enabled the design of a community-specific microarray for comparing multiple soil samples. The RST array was tested with pure cultures and by comparing soil hybridizations to denaturing gradient gel electrophoresis (DGGE) fingerprints from these same soils. Hybridization and DGGE results suggested that in contaminated soils, microbial communities were less diverse and had a higher proportion of predominant phylotypes. Several probe signals were correlated with HCH contamination (r>0.70), including one corresponding to Sphingomonas, a genus with known HCH degraders. Environmental parameters such as depth, pH and organic matter were also correlated with community structure in the soil samples.

description: We report measurements of the induced polarization $\vec P$ of protons knocked out from $^2$H and $^{12}$C via the $A(e,e'\vec p\,)$ reaction. We have studied the dependence of $\vec P$ on two kinematic variables: the missing momentum $p_{\rm miss}$ and the "off-coplanarity" angle $ϕ_{pq}$ between the scattering and reaction planes. For the full 360$\degree$ range in $ϕ_{pq}$, both the normal ($P_y$) and, for the first time, the transverse ($P_x$) components of the induced polarization were measured with respect to the coordinate system associated with the scattering plane. $P_x$ vanishes in coplanar kinematics, however in non-coplanar kinematics, it is on the same scale as $P_y$. We find that the dependence on $ϕ_{pq}$ is sine-like for $P_x$ and cosine-like for $P_y$. For carbon, the magnitude of the induced polarization is especially large when protons are knocked out from the $p_{3/2}$ shell at very small $p_{\rm miss}$. For the deuteron, the induced polarization is near zero at small $|p_{\rm miss}|$, and its magnitude increases with $|p_{\rm miss}|$. For both nuclei such behavior is reproduced qualitatively by theoretical results, driven largely by the spin-orbit part of the final-state interactions. However, for both nuclei, sizeable discrepancies exist between experiment and theory.

(1993) and de Bruyn (1996).A weak broad absorption feature reported by de Bruyn (1996) has not been detected in our observations. We also place an upper limit of 4 mJy (2 $σ$) on emission line strength at the position where Uson et al. (1991) claimed to have found a narrow emission line.

description: The present article provides a didactic presentation and extension of selected features of Pearl’s DAG-based approach to causal inference for researchers familiar with structural equation modeling. We illustrate key concepts using a cross-lagged panel design. We distinguish between (a) forecasts of the value of an outcome variable after an intervention and (b) predictions of future values of an outcome variable. We consider the mean level and variance of the outcome variable as well as the probability that the outcome will fall within an acceptable range. We extend this basic approach to include additive random effects, allowing us to distinguish between average effects of interventions and person-specific effects of interventions. We derive optimal person-specific treatment levels and show that optimal treatment levels may differ across individuals. We present worked examples using simulated data based on the results of a prior empirical study of the relationship between blood insulin and glucose levels.

description: Transition charge density (TCD) for $ 0^+\to 2_1^+ $ excitation have been calculated for $\rm ^{70,72,74,76}Ge$ nuclei within microscopic variational framework employing $2p_{3/2}, 1f_{5/2}, 2p_{1/2}$ and $1g_{9/2}$ valence space. The calculated TCDs for different monopole variants of Kuo interaction are compared with available experimental results. Other systematics like reduced transition probabilities B(E2) and static quadrupole moments Q(2) are also presented. It is observed that the transition density study acts as a sensitive probe for discriminating the response of different parts of effective interactions.

description: The use of reduced models for investigating the self-assembly dynamics underlying protein shell formation in spherical viruses is described. The spontaneous self-assembly of these polyhedral, supramolecular structures, in which icosahedral symmetry is a conspicuous feature, is a phenomenon whose dynamics remain unexplored; studying the growth process by means of computer simulation provides access to the mechanisms underlying assembly. In order to capture the more universal aspects of self-assembly, namely the manner in which component shapes influence structure and assembly pathway, in this exploratory study low-resolution approximations are used to represent the basic protein building blocks. Alternative approaches involving both irreversible and reversible assembly are discussed, models based on both schemes are introduced, and examples of the resulting behavior described.

description: The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2, emerged into a world being rapidly transformed by artificial intelligence (AI) based on big data, computational power and neural networks. The gaze of these networks has in recent years turned increasingly towards applications in healthcare. It was perhaps inevitable that COVID-19, a global disease propagating health and economic devastation, should capture the attention and resources of the world's computer scientists in academia and industry. The potential for AI to support the response to the pandemic has been proposed across a wide range of clinical and societal challenges, including disease forecasting, surveillance and antiviral drug discovery. This is likely to continue as the impact of the pandemic unfolds on the world's people, industries and economy but a surprising observation on the current pandemic has been the limited impact AI has had to date in the management of COVID-19. This correspondence focuses on exploring potential reasons behind the lack of successful adoption of AI models developed for COVID-19 diagnosis and prognosis, in front-line healthcare services. We highlight the moving clinical needs that models have had to address at different stages of the epidemic, and explain the importance of translating models to reflect local healthcare environments. We argue that both basic and applied research are essential to accelerate the potential of AI models, and this is particularly so during a rapidly evolving pandemic. This perspective on the response to COVID-19, may provide a glimpse into how the global scientific community should react to combat future disease outbreaks more effectively.

description: We show that the usual Hodge conjecture implies the general Hodge conjecture for certain abelian varieties of type III, and use this to deduce the general Hodge conjecture for all powers of certain 4-dimensional abelian varieties of type III. We also show the existence of a Hodge structure M such that M occurs in the cohomology of an abelian variety, but the Tate twist M(1) does not occur in the cohomology of any abelian variety, even though it is effective.

description: This paper measures the degree of market power of the Greek food and beverages manufacturing industry over the period 1983–2007 at the three-digit SIC level. The present study also estimates the “deadweight” loss and the reduction of consumers’ income due to the possible existence of market power in the Greek food and beverages manufacturing industry. Based on Bresnahan’s (1989) conjectural variation model, three different approaches are used to investigate competitive conditions of the Greek food and beverages manufacturing industry. The first approach assesses the extent of market power of the whole industry over the period 1983–2007; the second approach tests the degree of market power in each one of the nine sectors of the industry over the whole period, i.e. 1983–2007; and the third one estimates the extent of market power for the whole Greek food and beverages manufacturing industry for specific sub-periods of the period 1983–2007. The methodology of Dickson and Yu (1989) is adopted to measure the welfare losses. The empirical results indicate the presence of some degree of market power in the whole Greek food and beverages manufacturing industry as well as in each one sector of the industry during the period 1983– 2007 and, as a result, the existence of welfare losses. In addition, the empirical findings support the presence of some degree of market power for each sub-period of the period 1983– 2007 in the whole Greek food and beverages manufacturing industry and the existence of welfare losses.

description: We investigate an aggregation model with intrinsic interactions on the special orthogonal group $SO(3)$. We consider a smooth interaction potential that depends on the squared intrinsic distance, and establish local and global existence of measure-valued solutions to the model via optimal mass transport techniques. We also study the long-time behaviours of such solutions, where we present sufficient conditions for the formation of asymptotic consensus. The analytical results are illustrated with numerical experiments that exhibit various asymptotic patterns.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. 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.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We present a three-parameter neutrino-oscillation model for three flavors of massless neutrinos with Fermi-point splitting and tri-maximal mixing angles. One of these parameters is the T-violating phase ε, for which the experimental results from K2K and KamLAND appear to favor a nonzero value. In this article, we give further model predictions for neutrino oscillations. Upcoming experiments will be able to test this simple model and the general idea of Fermi-point splitting. Possible implications for proposed experiments and neutrino factories are also discussed.

Type IIA Killing spinors and calibrations

description: We consider the dimensional reduction of eleven dimensional supergravity to type IIA in ten dimensions, and study the conditions for supersymmetry in terms of p-form spinor bi-linears of the supersymmetry parameter. For a bosonic solution to be supersymmetric these p-forms must satisfy a set of differential relations, which we derive in full; the supersymmetry variations of the dilatino give a set of algebraic relations which are also derived. These results are then used to provide the generalized calibration conditions for some of the basic brane solutions, we also follow up a suggestion of Hackett-Jones and Smith and present a calibration condition for IIA supertubes. We find that a probe supertube satisfies this bound but does not saturate it, with the bound successfully accounting for the D0 charge of the supertube but not the string charge; we speculate that there should be a stronger calibration inequality than the one given.

description: There is a growing need for real-time characterization of droplet size distribution (DSD) for the continuously produced emulsions. In this study, we developed an at-line DSD characterization method using a turbidity-based soft sensor and demonstrated its application for continuously generated oil in water emulsions using a vortex-based hydrodynamic cavitation device. The concept of using an off-line turbidity meter and an ANN-based soft sensor for estimating DSD was recently demonstrated in our previous study. In this study, we further developed this concept for real-time characterization of DSD using an inexpensive, at-line turbidity meter providing an output in terms of voltage. Combined with the previously developed ANN-based soft sensor, the at-line voltage measurements were shown to be useful for the estimation of DSD and characteristic diameters. The emulsions of rapeseed oil (RO) in water with oil volume fractions of 0.15, 0.30, and 0.45 were produced in a continuous mode. Vortex-based cavitation device was used in a loop configuration with a key operating parameter being the ratio of the circulating flow rate through the loop (Q) and the net flow rate of emulsion (qnet). The influence of the Q/qnet ratio and volume fraction of oil on DSD, Sauter mean diameter (d32), other characteristic diameters, and droplet breakage efficiency (η) was investigated. The at-line turbidity measurements and ANN-based soft sensor were able to estimate the Sauter mean diameter within ±10% for oil volume fraction up to 0.45 and Q/qnet ratio up to 100. The developed methodology and results will be very useful for realizing decentralized and continuous emulsion production with at-line DSD measurements.

description: The superradiant instability of black hole space-times has been used to place limits on ultra-light bosonic particles. We show that these limits are model dependent. While the initial growth of the mode is gravitational and thus model independent, the ability to place a limit on new particles requires the mode to grow unhindered to a large number density. Non-linear interactions between the particle and other light degrees of freedom that are mediated through higher dimension operators can damp this growth, eliminating the limit. However, these non-linearities may also destroy a cosmic abundance of these light particles, an attractive avenue for their discovery in several experiments. We study the specific example of the QCD axion and show that it is easy to construct models where these non-linearities eliminate limits from superradiance while preserving their cosmic abundance.

The role of expectations and expectation errors in business cycles
Creators: name: Karnizova, Lilia Vladimirovna
Publisher: name: University of British Columbia
Year: 2009

description: What drives business cycles? Traditional explanations, based on policy interventions and supply side changes, have been found empirically incomplete. This thesis examines the relative contribution of changes in beliefs to business cycles from theoretical and empirical perspectives. The first essay evaluates quantitatively the U.S. investment boom and bust of the late 1990s and early 2000s. Revisions of optimistic beliefs are commonly viewed as the key determinant of investment during this period. Yet, can this view explain consistently the joint behaviour of consumption, investment and employment? A standard real business cycle model with technology shocks performs relatively well in capturing the boom, but very poorly in explaining the bust. Beliefs about future technology are introduced into this model by enriching the economy information set and identified from a discrepancy between the model and the data. The augmented model can only account for the joint behaviour of aggregate variables when expectations about the future are more pessimistic during the boom and more optimistic during the recession. The second essay derives and tests a necessary condition for beliefs about future technology to be an independent source of business cycles. The essay's premise is that expectations are rational, but current and past realizations of technology do not fully summarize information relevant for forecasting future technology. This premise necessarily implies long-run predictability of technology shocks. Measures of total factor productivity, orthogonal to monetary and fiscal policy shocks, provide empirical support for this premise in the U.S. post World War II period. Macroeconomic variables help to forecast future realizations of TFP growth up to two years. The third essay asks whether changes in beliefs due to extra information about the future (news shocks) are different from changes in beliefs due to extrinsic uncertainty (sunspot shocks). The essay incorporates news into linear rational expectations models with unique and multiple equilibria. Based on general forms of solutions and numerical simulations of a New Keynesian model, the essay demonstrates that news and sunspots have distinct predictions for dynamic properties of equilibria. Since the differences can be quantitatively significant, these predictions can be used to separate news and sunspots empirically.
