Experimental observations of upstream overdeepening
2005
The issue of morphodynamic influence in meandering streams is investigated through a series of laboratory experiments on curved and straight flumes. Both qualitative and quantitative observations confirm the suitability of the recent theoretical developments (Zolezzi & Seminara 2001) that indicate the occurrence of two distinct regimes of morphodynamic influence, depending on the value of the width ratio of the channel β. The threshold value βR separating the upstream from the downstream influence regimes coincides with the resonant value discovered by Blondeaux & Seminara (1985). Indeed it is observed that upstream influence may occur only in relatively wide channels, while narrower stream…
Emergence of statistically validated financial intraday lead-lag relationships
2014
According to the leading models in modern finance, the presence of intraday lead-lag relationships between financial assets is negligible in efficient markets. With the advance of technology, however, markets have become more sophisticated. To determine whether this has resulted in an improved market efficiency, we investigate whether statistically significant lagged correlation relationships exist in financial markets. We introduce a numerical method to statistically validate links in correlation-based networks, and employ our method to study lagged correlation networks of equity returns in financial markets. Crucially, our statistical validation of lead-lag relationships accounts for mult…
Collusion Constrained Equilibrium
2018
First published: 01 February 2018 This is an open access article licensed under the Creative Commons Attribution-NonCommercial License 4.0 (http://econtheory.org) We study collusion within groups in noncooperative games. The primitives are the preferences of the players, their assignment to nonoverlapping groups, and the goals of the groups. Our notion of collusion is that a group coordinates the play of its members among different incentive compatible plans to best achieve its goals. Unfortunately, equilibria that meet this requirement need not exist. We instead introduce the weaker notion of collusion constrained equilibrium. This allows groups to put positive probability on alternatives …
I congedi parentali e la genitorialità “intenzionale”
2021
Costituisce discriminazione diretta, ai sensi dell’art. 2, D.Lgs. 9 luglio 2003, n. 216, il diniego di usufruire del congedo parentale, previsto dall’art. 32, del D.Lgs. n. 151 del 2001 e dal contratto collettivo applicato, opposto dal datore di lavoro ad una propria lavoratrice, unita civilmente ad un’altra donna e “seconda madre” (la cosiddetta madre intenzionale) di un figlio avuto tramite ricorso a tecniche di procreazione medicalmente assistita, quando tale legame sia documentalmente certificato e provato dagli atti dello stato civile. Rientra, inoltre, nel novero delle discriminazioni dirette la dichiarazione d’intento con cui il datore di lavoro preannunci alla propria lavoratrice, “…
Special issue of Quantitative Finance on ‘Interlinkages and Systemic Risk’
2015
This special issue of Quantitative Finance collects eight papers on the relation between interlinkages and systemic risk. The papers cover several types of interlinkages and follow different approaches, from agent-based modelling to empirical investigation of large and sometimes confidential data. The special issue collects some of the contributions presented at the international workshop‘Interlinkages and systemic risk ’ , which took place in Ancona (Italy) on 4 – 5 July 2013. The workshop, organized within the research project‘. New tools in the credit network modeling with agents ’ heterogeneity ’ funded by the Institute for New Economic Thinking, was attended by a balanced mix of schola…

Itália: esquerda convertida à defesa do capital sofre derrota histórica para ultra-direita
2001
Itália. Abril de 1996. Aquele que fora o maior partido comunista do Ocidente vence as eleições italianas. O Partido da Refundação Comunista, nascido quando o PCI mudara de nome – Partido dos Democratas de Esquerda, PDS –, assumindo-se social-democrata, apoiara, de fora, a coligação. A vitória era completa, ao fim de seis meses de governo de Berlusconi, desorganizado por greves contra as privatizações, cortes sociais etc. Romano Prodi, em menos de dois anos, saneou as finanças, dobrou a inflação, relançou as exportações. Para realizar o milagre, comprimiu salários, cortou investimentos, privatizou bens públicos, causou graves seqüelas sociais. O governo de centro-esquerda dependia do apoio d…
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…
