Rahoitusmarkkinainformaatio BRIC-maiden laajennetussa Taylorin säännössä
2017
Tutkielmassa tarkastellaan BRIC-maiden harjoittamaa rahapolitiikkaa vuosina 2005-2015. Tutkielman päämääränä on selvittää, ovatko keskuspankit reagoineet rahapolitiikallaan inflaation ja tuotantokuilun lisäksi myös rahoitusmarkkinainformaatioon. Aineistona on käytetty reaaliaikaista aineistoa inflaation ja tuotantokuilun osalta. Rahoitusmarkkinainformaatiolla tarkoitetaan tutkielmassa kohdemaan valuuttakurssia ja keskimääräistä osinkotuottoa. Rahapolitiikkaa on arvioitu sekä sen hetkisten että eteenpäin katsovien Taylorin sääntöjen avulla. Rahoitusmarkkinainformaation roolia on tutkittu estimoimalla erilaisia rahoitusmarkkinainformaatiolla laajennettuja Taylorin sääntöjä ja arvioimalla laaj…
Latent heat flux variability and response to drought stress of black poplar: A multi-platform multi-sensor remote and proximal sensing approach to re…
2022
Abstract High-throughput mapping of latent heat flux (λET) is critical to efforts to optimize water resources management and to accelerate forest tree breeding for improved drought tolerance. Ideally, investigation of the energy response at the tree level may promote tailored irrigation strategies and, thus, maximize crop biomass productivity. However, data availability is limited and planning experimental campaigns in the field can be highly operationally complex. To this end, a multi-platform multi-sensor observational approach is herein developed to dissect the λET signature of a black poplar (Populus nigra) breeding population (“POP6”) at the canopy level. POP6 comprised more than 4600 …
On the use of fractional calculus for the probabilistic characterization of random variables
2009
In this paper, the classical problem of the probabilistic characterization of a random variable is re-examined. A random variable is usually described by the probability density function (PDF) or by its Fourier transform, namely the characteristic function (CF). The CF can be further expressed by a Taylor series involving the moments of the random variable. However, in some circumstances, the moments do not exist and the Taylor expansion of the CF is useless. This happens for example in the case of $\alpha$--stable random variables. Here, the problem of representing the CF or the PDF of random variables (r.vs) is examined by introducing fractional calculus. Two very remarkable results are o…
A method for the probabilistic analysis of nonlinear systems
1995
Abstract The probabilistic description of the response of a nonlinear system driven by stochastic processes is usually treated by means of evaluation of statistical moments and cumulants of the response. A different kind of approach, by means of new quantities here called Taylor moments, is proposed. The latter are the coefficients of the Taylor expansion of the probability density function and the moments of the characteristic function too. Dual quantities with respect to the statistical cumulants, here called Taylor cumulants, are also introduced. Along with the basic scheme of the method some illustrative examples are analysed in detail. The examples show that the proposed method is an a…
Stochastic analysis of dynamical systems with delayed control forces
2006
Abstract Reduction of structural vibration in actively controlled dynamical system is usually performed by means of convenient control forces dependent of the dynamic response. In this paper the existent studies will be extended to dynamical systems subjected to non-normal delta-correlated random process with delayed control forces. Taylor series expansion of the control forces has been introduced and the statistics of the dynamical response have been obtained by means of the extended Ito differential rule. Numerical application provided shows the capabilities of the proposed method to analyze stochastic dynamic systems with delayed actions under delta-correlated process contrasting statist…
Highlighting numerical insights of an efficient SPH method
2018
Abstract In this paper we focus on two sources of enhancement in accuracy and computational demanding in approximating a function and its derivatives by means of the Smoothed Particle Hydrodynamics method. The approximating power of the standard method is perceived to be poor and improvements can be gained making use of the Taylor series expansion of the kernel approximation of the function and its derivatives. The modified formulation is appealing providing more accurate results of the function and its derivatives simultaneously without changing the kernel function adopted in the computation. The request for greater accuracy needs kernel function derivatives with order up to the desidered …
Democratic institutions and recognition of individual identities
2016
This paper draws from two central intuitions that characterize modern western societies. The first is the normative claim that our identities should be recognized in an authentic way. The second intuition is that our common matters are best organized through democratic decision-making and democratic institutions. It is argued here that while deliberative democracy is a promising candidate for just organization of recognition relationships, it cannot fulfil its promise if recognition is understood either as recognition of ‘authentic’ collective identities or as recognition of too atomistic or individualized subjects. If deliberative democracy is to be understood as successfully providing au…
Insults, humour and freedom of speech
2016
In this article we argue that freedom of speech should be understood as a social freedom. In the public discussion after the Charlie Hebdo attacks, it has often been understood as an absolute right to say anything – to offend, to make a fool of others and of oneself, and to express any opinion regardless of the consequences. We challenge this view and propose that advocating freedom of speech without understanding its social foundations is misleading and counterproductive. Based on the critical social theories of Erich Fromm, Charles Taylor and Axel Honneth, we show that there is an alternative tradition in which freedom is fundamentally rooted in social relations and therefore requires re…
Stock market and exchange rate information in the Taylor rule : Evidence from OECD countries
2017
We analyze the effects of stock market and exchange rate information in a forward-looking Taylor rule for monthly data from 14 OECD countries during the years 1999–2016. Especially the stock market information in the form of dividend but also the currency market information in the form of real exchange rate are revealed to be relevant in Taylor rule for many of the countries examined by helping to strengthen the role of inflation and real economic activity deviations in the policy rule. In many cases the rule also seems to be opportunistic, i.e., the inflation target has been time-varying. peerReviewed
The New Consensus and Post-Keynesian Interest Rate Policy.
2007
Abstract This paper outlines the fundamental arguments of the New Consensus, critiques it from a Post-Keynesian perspective, and offers a Post-Keynesian alternative to the Taylor Rule. While Post-Keynesian economics provides a theory of endogenous money with exogenous interest rates, it has no clear description of a central bank reaction function. We attempt to remedy this oversight by identifying some of the difficulties attached to developing a Post-Keynesian reaction function, and suggesting an approach to the setting of interest rates that is more consistent than the Taylor Rule with Keynes's General Theory.
