description: The impact of nuclear physics theories on cooling of isolated neutron stars is analyzed. Physical properties of neutron star matter important for cooling are reviewed such as composition, the equation of state, superfluidity of various baryon species, neutrino emission mechanisms. Theoretical results are compared with observations of thermal radiation from neutron stars. Current constraints on theoretical models of dense matter, derived from such a comparison, are formulated.

description: Recent research on perovskite solar cells has caught much attention for the application in renewable energy materials. However, the effect of external dopants on the performance of perovskite solar cell is yet to be understood properly. Oxygen atom or molecule is important dopant to influence the stability of structural, electronic and optical properties as well as the performance of perovskite solar cells. RbPbX3-type perovskites have fantastic chemical stability and good power conversion efficiency. Here for the first time, we have studied the effect of interstitial oxygen atom (O1) and molecule (O2) on the structural properties, and hence the electronic structure of RbPbI3 from first principles. A significant reduction of the band gap from ~2.6 eV to ~ 1.0 eV, which is close to the optimal band gap, has been predicted when incorporating oxygen. This could in turn be applied to improve the optical properties for harvesting light if we can control the oxygen level appropriately. In addition, an exotic metallic state has been found in our calculations for interstitial oxygen molecule when there are strong O-O, O-Pb, and O-I bonds, indicating the complex nature of oxygen-doped perovskite solar cells. The comparison between oxygen atom and molecules is consistent with the previous report about oxygen-molecule passivation of perovskite solar cells. This indicated oxygen incorporation can not only improve efficiency and stability but also facilitate the optimal band-gap engineering. Our work has therefore provided an important and timely theoretical insight to the effect of oxygen dopants in perovskite solar cells. Moreover, these results also provide theoretical foundation for further simulations such as molecular dynamics.

description: It has often been claimed that the international debt crisis has been made worse by the high level of interest rates payable on the debt. The purpose of this article is to analyse the recent evolution of interest rates and the contribution this has made to precipitating the crisis. A recent history of interest rate movements is presented, together with some relevant debt figures. This leads to an examination of various explanations of the debt crisis and the role that high interest rates may have played in the problem. JEL: E43, F34, G01

Hitting all maximum stable sets in $P_5$-free graphs

description: We prove that every $P_5$-free graph of bounded clique number contains a small hitting set of all its maximum stable sets.
 More generally, let us say a class $\mathcal{C}$ of graphs is $η$-bounded if there exists a function $h:\mathbb{N}\rightarrow \mathbb{N}$ such that $η(G)\leq h(ω(G))$ for every graph $G\in \mathcal{C}$, where $η(G)$ denotes smallest cardinality of a hitting set of all maximum stable sets in $G$, and $ω(G)$ is the clique number of $G$. Also, $\mathcal{C}$ is said to be polynomially $η$-bounded if in addition $h$ can be chosen to be a polynomial.
 We introduce $η$-boundedness inspired by a question of Alon and motivated by a number of meaningful similarities to $χ$-boundedness. In particular, we propose an analogue of the Gyárfás-Sumner conjecture, that the class of all $H$-free graphs is $η$-bounded if (and only if) $H$ is a forest. Like $χ$-boundedness, the case where $H$ is a star is easy to verify, and we prove two non-trivial extensions of this: $H$-free graphs are $η$-bounded if (1) $H$ has a vertex incident with all edges of $H$, or (2) $H$ can be obtained from a star by subdividing at most one edge, exactly once.
 Unlike $χ$-boundedness, the case where $H$ is a path is surprisingly hard. Our main result mentioned at the beginning shows that $P_5$-free graphs are $η$-bounded. The proof is rather involved compared to the classical ``Gyárfás path'' argument which establishes, for all $t$, the $χ$-boundedness of $P_t$-free graphs. It remains open whether $P_t$-free graphs are $η$-bounded for $t\geq 6$. It also remains open whether $P_5$-free graphs are polynomially $η$-bounded, which, if true, would imply the Erdős-Hajnal conjecture for $P_5$-free graphs. But we prove that $H$-free graphs are polynomially $η$-bounded if $H$ is a proper induced subgraph of $P_5$.

Harrod and Domar on dynamic economics

Subjects: subject: Harrod, Domar, theory of growth, dynamic economics
subject: B22, O40

description: Although Harrod and Domar developed their theories of growth independently, most economists became aware of them at roughly the same time. Both authors broke out of the static framework of Keynes’ General Theory by recognising the productive-capacity creating, as well as the aggregate-demand creating, effects of investment. Their equilibrium rates of growth appeared to be the same and thus the two approaches were joined in textbooks and in numerous articles and the Harrod-Domar model. Despite their similarities, however, there were significant differences in their approaches to dynamic economics and the theory of growth. The present paper offers a comparison of these theories to help better understand the strengths and weaknesses of both. JEL: B22, O40

description: Deep learning-based change detection (CD) using remote sensing images has received increasing attention in recent years. However, how to effectively extract and fuse the deep features of bi-temporal images for improving the accuracy of CD is still a challenge. To address that, a novel adjacent-level feature fusion network with 3D convolution (named AFCF3D-Net) is proposed in this article. First, through the inner fusion property of 3D convolution, we design a new feature fusion way that can simultaneously extract and fuse the feature information from bi-temporal images. Then, to alleviate the semantic gap between low-level features and high-level features, we propose an adjacent-level feature cross-fusion (AFCF) module to aggregate complementary feature information between the adjacent levels. Furthermore, the full-scale skip connection strategy is introduced to improve the capability of pixel-wise prediction and the compactness of changed objects in the results. Finally, the proposed AFCF3D-Net has been validated on the three challenging remote sensing CD datasets: the Wuhan building dataset (WHU-CD), the LEVIR building dataset (LEVIR-CD), and the Sun Yat-Sen University dataset (SYSU-CD). The results of quantitative analysis and qualitative comparison demonstrate that the proposed AFCF3D-Net achieves better performance compared to other state-of-the-art methods.

The effect of static disorder on the center line slope in 2D electronic spectroscopy

description: Two-dimensional electronic spectroscopy (2DES) is a powerful tool for investigating the dynamics of complex systems. However, analyzing the resulting spectra can be challenging, and thus may require the use of theoretical modeling techniques. The center line slope (CLS) method is one of such approaches, which aims to extract the time correlation function (TCF) from 2DES with minimal error. Since static disorder is widely observed in complex systems, it may be interesting to ask whether the CLS approach still work in the presence of the static disorder. In this paper, the effect of the static disorder on the TCF obtained through the CLS method is investigated. It is found that the steady-state value of the CLS increases monotonically with respect to the static disorder, which suggests that the amplitude of the static disorder can be determined using the CLS in the long-time limit. Additionally, as the static disorder rises, the decay rate of the CLS first decreases to a certain value and remains at this value until the static disorder is sufficiently large. Afterward, the CLS begins to fluctuate significantly and thus results in obtaining the decay rate through the CLS method unreliable. Based on these discoveries, we propose a method to fix the error and obtain the TCF. Our findings may pave the way for obtaining reliable system-bath information by analyzing 2DES in the practical situations.

subject: E41, E58, O53

description: Many developing countries lack an established money market. Often this is because the banking system is unsophisticated and does not require a money market, or else there may be no central bank to oversee and foster the development of a market. In the case of Thailand, an extensive banking system and a well established central bank are both present. After considering how a money market might help in extending the range of financial services, the author examines the main instruments and characteristics that such a market might develop. This leads to some suggestions on how such a market could be established. JEL: E41, E58, O53

Indian Pine Needles: A Multifaceted Resource with Emerging Applications in Floriculture and Food Science

Year: 2024

description: India's Himalayan landscape is renowned for its towering coniferous forests, which stretch across vast terrains, offering a striking contrast between rugged mountains and lush greenery. One of the key species found in these forests is Pinus roxburghii, commonly known as Chir Pine, which plays a crucial role in the region's ecological balance. These pine trees are not only symbolic of the Himalayan ecosystem but also significant contributors to local economies through timber, resin and handicrafts. However, there is one aspect of these majestic trees that has often been overlooked or viewed as problematic: their fallen needles. Indian pine needles, particularly from Chir Pine, form a thick layer on the forest floor as they fall naturally throughout the year. Long, thin and resilient, these needles are rich in cellulose and lignin, which makes them slow to decompose and resistant to natural breakdown. This quality, while adding to the beauty of the landscape, poses a serious environmental challenge in the form of fire hazards. Accumulation of dry needles, especially during the warmer months, becomes highly combustible, turning the region into a fire-prone zone. Forest fires fueled by pine needles not only devastate local biodiversity but also threaten human settlements. Historically, these fallen pine needles were seen as little more than a nuisance or a potential fire hazard. However, a shift in perspective is underway. With increasing awareness of environmental conservation, sustainable practices and resource utilization, pine needles are now emerging as a valuable natural resource with diverse applications, particularly in the floriculture and food science industries. No longer dismissed as waste, these resilient needles are proving to be a multi-faceted bioresource capable of contributing to several eco-friendly and economically viable industries.

description: We report on optical spectroscopy of the eclipsing Halo LMXB 2S0921-630, that reveals the absorption line radial velocity curve of the K0III secondary star with a semi-amplitude K_2=92.89 +/- 3.84 km/s, a systemic velocity $γ$=34.9 +/- 3.3 \kms and an orbital period P_orb of 9.0035 +/- 0.0029 day (1-sigma). Given the quality of the data, we find no evidence for the effects of X-ray irradiation. Using the previously determined rotational broadening of the mass donor, and applying conservative limits on the orbital inclination, we constrain the compact object mass to be 2.0-4.3 Msolar (1-sigma), ruling out a canonical neutron star at the 99% level. Since the nature of the compact object is unclear, this mass range implies that the compact object is either a low-mass black hole with a mass slightly higher than the maximum neutron star mass (2.9 Msolar) or a massive neutron star. If the compact object is a black hole, it confirms the prediction of the existence of low-mass black holes, while if the object is a massive neutron star its high mass severely constrains the equation of state of nuclear matter.

description: Die Straße ist ein öffentlicher Raum, der uns so geläufig ist, dass wir ihn kaum wahrnehmen. In Shanghai ist sie ein Lebensraum, in Wien viel zu oft nur Verkehrsfläche und Parkraum. Das zunehmende Wachstum und die Verdichtung der Städte stellen den Straßenraum vor große Herausforderungen. Meine Masterarbeit ist eine Aufforderung zur Entdeckung von verborgenen Potenzialen im Straßenraum und appelliert an die Förderung spontaner Architektur. Die Straße, die der Urbanismus geometrisch festlegt, wird durch den Gehenden in einen Raum verwandelt. Straßenräume bilden unsere Alltagsräume, an denen wir viel über unsere Kultur, Politik und Ökonomie ablesen können. Ein Blick nach Shanghai weist daher über europäische Sicht- und Denkweisen hinaus, hinterfragt unsere gewohnte Auffassung und die Rolle, die wir ihr als öffentlichen Raum zuschreiben. Die Bedeutung der Raumwahrnehmung wird durch die bildbasierte Forschung, aber auch durch die Gegenüberstellung von asiatischen und europäischen Raumverständnissen, dargestellt. Fotografische, subjektive Eindrücke werden von theoretischen Überlegungen begleitet. Wort und Bild ergänzen einander und produzieren auf ihre Weise eine spezifische Art von Wissen. Weitere "Werkzeuge" helfen dabei Antworten auf folgende Forschungsfragen zu liefern: Inwiefern produziert menschliches Handeln öffentlichen Raum?
description: The street is a public space, which is so familiar to us that we hardly notice it. In Shanghai it represents the setting for every day life, whereas in Vienna it is more of a traffic area and a parking space. The increasing growth and densification of cities represent a big challenge for the street space. The framework of my study invites to discover the hidden potentials of this urban space and promotes spontaneous architecture. Street spaces represent our everyday surroundings from which we can learn a lot about our culture, politics and economics. A close look at Shanghai therefore points beyond the European ways of thinking and perception, questioning our usual conception, providing a basis for the development of creative criteria and proposing new strategies for the use of urban street spaces. The meaning of "spatial perception" is being explored through an image-based research, but also through the juxtaposition of Asian and European understanding of the urban space. Other "tools" help providing an answer to the following research questions, such as: To what extent does human behavior produce the "city"? What actions produce certain spaces? What can we learn from the prevailing in order to improve the quality of public spaces?
Structural change, foreign trade and income multipliers in the Italian economy

description: Between 1960 and 1985 the international integration of the Italian economic system increased substantially, with the pattern of trade changing significantly over the last decade. The literature that analysed these trends in relation to the process of structural change in the productive system has given rise to a debate on the macroeconomic implications of the changes taking place. This paper presents a macroeconomic framework for the consequences of these structural changes. The authors first focus on the links between imports and final demand. Then, these structural features of the system are embodied in a macroeconomic model. Finally, this model is used as a conceptual framework to analyse some macro-economic implications of the structural changes discussed in the literature. JEL: F15, N24

Block-encoding structured matrices for data input in quantum computing

description: The cost of data input can dominate the run-time of quantum algorithms. Here, we consider data input of arithmetically structured matrices via block encoding circuits, the input model for the quantum singular value transform and related algorithms. We demonstrate how to construct block encoding circuits based on an arithmetic description of the sparsity and pattern of repeated values of a matrix. We present schemes yielding different subnormalisations of the block encoding; a comparison shows that the best choice depends on the specific matrix. The resulting circuits reduce flag qubit number according to sparsity, and data loading cost according to repeated values, leading to an exponential improvement for certain matrices. We give examples of applying our block encoding schemes to a few families of matrices, including Toeplitz and tridiagonal matrices.
title: Investigating the infinite spider's web in complex dynamics
Creators: name: Osborne, John William
Publisher: name: The Open University
Year: 2012

description: This thesis contains a number of new results on the topological and geometric properties of certain invariant sets in the dynamics of entire functions, inspired by recent work of Rippon and Stallard. First, we explore the intricate structure of the spider's web fast escaping sets associated with certain transcendental entire functions. Our results are expressed in terms of the components of the complement of the set (the 'holes' in the web). We describe the topology of such components and give a characterisation of their possible orbits under iteration. We show that there are uncountably many components having each of a number of orbit types, and we prove that components with bounded orbits are quasiconformally homeomorphic to components of the filled Julia set of a polynomial. We prove that there are singleton periodic components and that these are dense in the Julia set. Next, we investigate the connectedness properties of the set of points K( f) where the iterates of an entire function f are bounded. We describe a class of transcendental entire functions for which K( f) is to- tally disconnected if and only if each component of K (f) containing a critical point is aperiodic. Moreover we show that, for such functions, if K(f) is disconnected then it has uncountably many components. We give examples of functions for which K(f) is totally disconnected, and we use quasiconformal surgery to construct a function for which K(f) has a component with empty interior that is not a singleton. Finally we show that, if the Julia set of a transcendental entire function is locally connected, then it must take the form of a spider's web. In the opposite direction, we prove that a spider's web Julia set is always locally connected at a dense subset of buried points. We also show that the set of buried points (the residual Julia set) can be a spider's web.

Inelastic Final State Interactions in $B \to PP$ Decays
Creators: name: Zenczykowski, P.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A method parametrizing all inelastic final state interactions (FSI) in $B\to PP$ decays is presented ($P$ - pseudoscalar meson). The method explicitly shows how rescattering leads to the replacement of the short-distance amplitudes with the effective quark diagram amplitudes, and how it affects the extraction of the unitarity triangle angle $γ$ from the data. It is furthermore pointed out that the size of FSI effects cannot be determined from $B^0_d \to K^+ K^-$ decays in a satisfactory way. The case of SU(3)-violating FSI is also discussed. When fits to the branching ratios of all $B \to PP$ decays are performed with all inelastic FSI included, the extracted value of $ γ$ is shifted down by some $20^o-30^o$ when compared to the no-FSI analyses, and becomes consistent with the Standard Model value of $ 65^o \pm 7^o$.

title: The disposition effect, dual process theory and emotion regulation
Creators: name: Richards, Daniel William
Publisher: name: The Open University
Year: 2013

description: Research from the behavioural finance paradigm has detected bias in investors' decision making. One such bias, the disposition effect, shows that investors are reluctant to sell investments at a loss, yet are eager to sell investments at a gain. Investors vary in the extent to which they exhibit the disposition effect and research to date has found that an investor's level of sophistication and amount of experience can somewhat predict their susceptibility to this bias. Despite the disposition effect arising out of the nature of human psychology, few studies have empirically investigated psychological based explanations for susceptibility to this bias. I address this gap by applying two psychological theories to predict the susceptibility to the disposition effect: dual process theory and a model of the role of emotions and their regulation. The thesis contains two studies on the disposition effect of UK investors, a country where investors have not previously been researched for this bias. The first study involves using survival analysis to analyse the transactions made by 4,328 UK investors from July 2006 to December 2009. The second study is a subsample ofthe first, where 261 investors completed an online questionnaire to measure the psychological variables. I show that the average UK investor in this sample is susceptible to the disposition effect. contribute to existing knowledge about the disposition effect by showing that investor sophistication and experience attenuates, but does not eliminate, this bias. I extend knowledge on the disposition effect by showing that through the use of stop loss strategies, investors can inoculate against the disposition effect. In relation to the psychological variables, I find that investors who report higher levels of intuitive ability exhibit this bias to greater extent and investors who report a preference towards analytical cognition exhibit this bias to a lesser extent. Finally, the results tentatively show that investors who reappraise their emotions while investing, exhibit this bias to a lesser extent.

In particular, it has been shown that in the geometrical optics limit, the model is integrable and it is governed by the dispersionless Veselov-Novikov (dVN) equation. Burgers-Hopf equation can be obtained as 1+1-dimensional reduction of dVN equation. We discuss its properties in the specific context of nonlinear geometrical optics. An illustrative explicit example is considered.

description: With the explosive increase of User Generated Content (UGC), UGC video quality assessment (VQA) becomes more and more important for improving users' Quality of Experience (QoE). However, most existing UGC VQA studies only focus on the visual distortions of videos, ignoring that the user's QoE also depends on the accompanying audio signals. In this paper, we conduct the first study to address the problem of UGC audio and video quality assessment (AVQA). Specifically, we construct the first UGC AVQA database named the SJTU-UAV database, which includes 520 in-the-wild UGC audio and video (A/V) sequences, and conduct a user study to obtain the mean opinion scores of the A/V sequences. The content of the SJTU-UAV database is then analyzed from both the audio and video aspects to show the database characteristics. We also design a family of AVQA models, which fuse the popular VQA methods and audio features via support vector regressor (SVR). We validate the effectiveness of the proposed models on the three databases. The experimental results show that with the help of audio signals, the VQA models can evaluate the perceptual quality more accurately. The database will be released to facilitate further research.

description: We introduce a new kind of foliated quantum field theory (FQFT) of gapped fracton orders in the continuum. FQFT is defined on a manifold with a layered structure given by one or more foliations, which each decompose spacetime into a stack of layers. FQFT involves a new kind of gauge field, a foliated gauge field, which behaves similar to a collection of independent gauge fields on this stack of layers. Gauge invariant operators (and their analogous particle mobilities) are constrained to the intersection of one or more layers from different foliations. The level coefficients are quantized and exhibit a duality that spatially transforms the coefficients. This duality occurs because the FQFT is a foliated fracton order. That is, the duality can decouple 2+1D gauge theories from the FQFT through a process we dub exfoliation.

description: DMP have been extensively applied in various robotic tasks thanks to their generalization and robustness properties. However, the successful execution of a given task may necessitate the use of different motion patterns that take into account not only the initial and target position but also features relating to the overall structure and layout of the scene. To make DMP applicable to a wider range of tasks and further automate their use, we design a framework combining deep residual networks with DMP, that can encapsulate different motion patterns of a planar task, provided through human demonstrations on the RGB image plane. We can then automatically infer from new raw RGB visual input the appropriate DMP parameters, i.e. the weights that determine the motion pattern and the initial/target positions. We compare our method against another SoA method for inferring DMP from images and carry out experimental validations in two different planar tasks.

description: Objective: To investigate the value of Philips 256-slice iCT1024 matrix perfusion imaging in the diagnosis of solitary pulmonary nodules (SPN).Methods: A total of 38 patients with SPN underwent perfusion scan, the scanned data was sent to EBW workstation, the images were analyzed by pulmonary nodules analysis software to obtain the indexes of blood flow (BF), blood volume (BV), mean transit time (MTT), peak height (PH) and ratio of SPN to aortic PH (S/A). The indexes underwent statistical analysis, and were compared with pathological results. Results: The BV, PH and S/A ratio values of malignant and inflammatory nodules were significantly higher than those of benign nodules (P<0.01), while the BV, PH and S/A ratio values between malignant and inflammatory nodules were no statistically significant (P>0.05). The TDC appeared different for malignant, inflammatory and benign nodules. Conclusion: 256-slice iCT1024 matrix perfusion imaging can help to identify the benign or malignant of SPN.

description: We present ab initio time-dependent-density-functional calculations and non-resonant inelastic x-ray scattering measurements of the dynamical structure factor of rutile TiO2. Our calculations are in good agreement with experiment and prove the presence of large crystal local-field effects below the Ti M-edge, which yield a sharp loss peak at 14 eV whose intensity features a remarkable non-monotonic dependence on the wave vector. These effects, which impact the excitation spectra in the oxide more dramatically than in transition metals, provide a signature of the underlying electronic structure.

subject: F36, G15

description: Financial markets around the world are undergoing similar experiences of innovation and conglomeration. This paper reviews those trends and considers the policy implications and the movement towards the integration of the world's capital markets. In particular, the risks and how they can be contained are examined. This leads to an examination of the issues raised by the liberalisation of capital transactions and the implications for the prospects of greater integration of financial markets in Europe.

Generalized optimal statistic for characterizing multiple correlated signals in pulsar timing arrays

description: The optimal statistic (OS) is a frequentist estimator for the amplitude and significance of a spatially-correlated signal in pulsar timing array (PTA) data, and it is widely used to search for the gravitational wave background (GWB). However, the OS cannot perfectly distinguish between different spatial correlations. In this paper, we introduce the multiple component optimal statistic (MCOS): a generalization of the OS that allows for multiple correlations to be simultaneously fit to the data. We use simulated data to show that this method more accurately recovers injected spatially correlated signals, and in particular reduces the risk of a false detection of a signal with the wrong spatial correlation. We also demonstrate that this method can be used to recover multiple correlated signals.

description: A displacement-based, geometrically nonlinear finite element model is developed for lattice core sandwich panels modeled as 2-D equivalent single-layer (ESL), first-order shear deformation theory (FSDT) micropolar plates. The nonlinearity is due to the moderate macrorotations of the plate which are modeled by including the von Karman strains in the micropolar strain measures. Weak form Galerkin method with linear Lagrange interpolations is used to develop the displacement-based finite element model. Selective reduced integration is used to eliminate shear locking and membrane locking. The novel finite element model is used to study the nonlinear bending and linear free vibrations of web-core and pyramid core sandwich panels. Clamped and free edge boundary conditions are considered for the first time for the 2-D micropolar ESL-FSDT plate theory. The present 2-D finite element results are in good agreement with the corresponding detailed 3-D FE results for the lattice core sandwich panels. The 2-D element provides computationally cost-effective solutions; in a nonlinear bending example, the number of elements required for the 2-D micropolar plate is of the order 10^3, whereas for the corresponding 3-D model the order is 10^5.

description: In the past two decades another transistor based on conducting polymers, called the organic electrochemical transistor (ECT) was shown and largely studied. The main difference between organic ECTs and FETs is the mode and extent of channel doping: while in FETs the channel only has surface doping through dipoles, the mixed ionic-electronic conductivity of the channel material in Organic ECTs enables bulk electrochemical doping. As a result, the organic ECT maximizes conductance modulation at the expense of speed. Until now ECTs have been based on conducting polymers, but here we show that MXenes, a class of 2D materials beyond graphene, have mixed ionic-electronic properties that enable the realization of electrochemical transistors (ECTs). We show that the formulas for organic ECTs can be applied to these 2D ECTs and used to extract parameters like mobility. These MXene ECTs have high transconductance values but low on-off ratios. We further show that conductance switching data measured using ECT, in combination with other in-situ ex-situ electrochemical measurements, is a powerful tool for correlating the change in conductance to that of redox state: to our knowledge, this is the first report of this important correlation for MXene films. Many future possibilities exist for MXenes ECTs, and we think other 2D materials with bandgaps can also form ECTs with single or heterostructured 2D materials. 2D ECTs can draw great inspiration and theoretical tools from the field of organic ECTs and have the potential to considerably extend the capabilities of transistors beyond that of conducting polymer ECTs, with added properties such as extreme heat resistance, tolerance for solvents, and higher conductivity for both electrons and ions than conducting polymers.

description: The author sees signs that the European Community is entering a phase of steady economic growth, with inflation under control and a favourable outlook for exports. However, these assumptions are dependent on other trading nations getting a firmer control over their domestic fiscal and monetary policies. In particular, the US federal budget deficit will remain a problem, as will the continuing balance of trade surplus in Japan. The major problem for the European countries will remain unemployment.

Did the Keynesian revolution retard the development of portfolio theory?

description: In 1935 Hicks put forward a framework for monetary theory which contained the essence of portfolio theory. Twenty years passed before Tobin then picked up this research and developed it further, going on to receive the nobel prize in 1981. This work explains this gap by hypothesising that with the Keynesian Revolution, research became concentrated on the real sector of the economy, while the monetary sector was represented by the money demand function. As attention become centred on the real sector, the monetary sector was narrowed to the demand for money function. JEL: B22, E40
