Unconventional monetary policy reaction functions: evidence from the US
2020
Abstract We specify unconventional monetary policy reaction functions for the Fed using linear and nonlinear econometric frameworks. We find that nonstandard policy measures are largely driven by the dynamics of inflation and the output gap, with the effect being particularly strong during QE rounds. Moreover, we uncover the presence of asymmetry and regime dependence in central bank’s actions since the global financial crisis, especially concerning the response of the term spread and the shadow short rate to the growth rate of central bank reserves. From a policy perspective and given the lack of a systematic response of monetary policy to asset price growth in nonstandard times, our findi…
Effects of Fiscal Stimulus in Structural Models
2010
The paper assesses, using seven structural models used heavily by policymaking institutions, the effectiveness of temporary fiscal stimulus. Models can, more easily than empirical studies, account for differences between fiscal instruments, for differences between structural characteristics of the economy, and for monetary-fiscal policy interactions. Findings are: (i) There is substantial agreement across models on the sizes of fiscal multipliers. (ii) The sizes of spending and targeted transfers multipliers are large. (iii) Fiscal policy is most effective if it has some persistence and if monetary policy accommodates it. (iv) The perception of permanent fiscal stimulus leads to significant…
Supplier switching decisions
2007
Abstract In order to maximize profit, a buying firm should continuously search for and access sources which offer more favorable prices. While the literature is replete with works on the formation and development of buyer–supplier relationships, there is surprisingly only scarce research on the termination of such relationships and supplier switching. Using the concept of switching costs in a principal-agent framework, we at first analyze whether a firm switches the entire or a partial quantity to an alternative supplier when there is either symmetric or asymmetric information about the alternative supplier’s cost structure. Information asymmetry results in inert supplier switching decision…
An Efficient and Secure Multidimensional Data Aggregation for Fog-Computing-Based Smart Grid
2021
International audience; The secure multidimensional data aggregation (MDA) has been widely investigated in smart grid for smart cities. However, previous proposals use heavy computation operations either to encrypt or to decrypt the multidimensional data. Moreover, previous fault-tolerant mechanisms lead to an important computation cost, and also a high communication cost when considering a separate identification phase. In this article, we propose an efficient and secure MDA scheme, named ESMA. Unlike existing schemes, the multidimensional data in ESMA are structured and encrypted into a single Paillier ciphertext and thereafter, the data are efficiently decrypted. For privacy preserving, …
Impatto potenziale dei programmi sviluppabili dal Distretto in termini di innovazione, sviluppo e risparmio energetico sulle imprese della filiera
2014
Se da un lato l’energia ed il suo costo rappresentano da tempo una delle più serie limitazioni alla sostenibilità del settore della pesca, dall’altro lato affrontare questo tema in un’ottica di innovazione può costituire un interessante fattore di sviluppo e di innovazione del settore stesso. Non è del resto un caso che ai temi della sostenibilità siano ispirate le linee guida del nuovo programma europeo Horizon 2020, Work Programme 2014-2010; come è noto, tra le sette sfide principali del programma europeo, una è espressamente riservata alla ricerca marina e marittima (“Food Security, Sustainable Agriculture, Marine and maritime research and the bio-economy”). Nell’ambito dei programmi svi…
Hospitalizations of patients in Burgundy and in nine other french regions, spatial analysis of interregional flows from french hospital claims data
2015
Introduction / presentation of the context : The creation of ARS (Regional Healthcare Agencies) was accompanied by the regionalized organization of healthcare. Even though the administrative procedures for dividing the country into areas for healthcare coverage are well known, we propose a geographic analysis of the reasons why patients attend one hospital rather than another, which seem to escape the logic used by the authorities.Methods employed and sources of data : Using the PMSI-MCO, we studied the flow of patients living in one region to hospitals in other regions according to ten reasons for visiting hospitals. The analysis was completed by a cartographic analysis, which related the …
Actuaciones procesales de la mujer en Roma. Prohibición edictal y literatura jurídica
2020
[Resumen] La improcedencia moral de que las mujeres usen de la palabra en el ámbito público, que se refiere a los lugares de espacio relevante como es el forum o intervengan en actos jurídicos formales, especialmente los solemnia verba, no impide que pueda intervenir procesalmente en defensa de asuntos propios y ajenos, aunque esta postulatio se traten de virilibus officiis. De esta forma la intervención de la mujer en la defensa de asuntos propios y ajenos aparece como algo poco común pero no prohibido hasta finales de la república. Un edicto de la primera mitad del s. I a. C, introduce el impedimento general de que intervenga la mujer en los procesos ajenos. La contradictoria afirmación q…
Lagrangian dynamics and possible isochronous behavior in several classes of non-linear second order oscillators via the use of Jacobi last multiplier
2015
Abstract In this paper, we employ the technique of Jacobi Last Multiplier (JLM) to derive Lagrangians for several important and topical classes of non-linear second-order oscillators, including systems with variable and parametric dissipation, a generalized anharmonic oscillator, and a generalized Lane–Emden equation. For several of these systems, it is very difficult to obtain the Lagrangians directly, i.e., by solving the inverse problem of matching the Euler–Lagrange equations to the actual oscillator equation. In order to facilitate the derivation of exact solutions, and also investigate possible isochronous behavior in the analyzed systems, we next invoke some recent theoretical result…
