Shallow and Deep Integration
2021
The concepts of shallow and deep economic integration are introduced and discussed as to their pertinence. The conflicting results of successive rounds of global trade negotiations for developing and least developed countries are examined in the context of deep integration attempts in North-South agreements. It is established as a guiding principle that North-South agreements should normally not go deeper or run faster than South-South agreements. In light of observed global trends, upcoming inter-regional trade deals will differ from current preferential North-South trade agreements, and Northern partners will be adamant that future agreements should go deep, as the chapter critically disc…
Selection by committee: Anonymity and gratitude
2018
Abstract What kind of candidate is selected into a job when the principal has to appoint a committee to measure the candidates’ ability and select a winner? We find that if the committee takes into account the candidate’s gratitude towards them, a candidate with less than first best ability will be selected. A relevant exception may occur if the first best is the overall best candidate. First best selection is always achieved if the committee is anonymous to the candidates. If the committee is not detached enough from the candidates then delegation fares even worse than random selection.
Networked relationships in the e-MID Interbank market: A trading model with memory
2014
Interbank markets are fundamental for bank liquidity management. In this paper, we introduce a model of interbank trading with memory. Our model reproduces features of preferential trading patterns in the e-MID market recently empirically observed through the method of statistically validated networks. The memory mechanism is used to introduce a proxy of trust in the model. The key idea is that a lender, having lent many times to a borrower in the past, is more likely to lend to that borrower again in the future than to other borrowers, with which the lender has never (or has in- frequently) interacted. The core of the model depends on only one parameter representing the initial attractiven…
When financial economics influences physics: The role of Econophysics
2019
This paper aims at analyzing the unexpected influence of Financial economics on Physics. The rise of Econophysics, a fundamentally new approach in finance, suggests that the influence between the two disciplines becomes less unilateral than in the past. Methodological debates emerging in Econophysics led physicists to acknowledge that dealing with financial complex systems contributed to a wider modelling of their field. The approach of econophysicists suggests that physicists might try to conceptualize physical phenomena by integrating elements they faced with in Financial economics, and more generally in Economics. Surprisingly, many of econophysicists’ argumentations have some methodolog…
Trust and punishment
2021
Abstract This paper explores the impact of institutions on the evolution of preferences (culture) and on economic outcomes. Punishment institutions determine the capacity and the individual cost of punishing opportunistic behavior, while preferences are endogenous and can be influenced by a cultural transmission process that is conditioned by the existing punishment institutions. We investigate the interaction and evolution between the preferences for reciprocity or rewarding of the allocator and the preferences to punish hostile behaviour by the investor in a trust game with a costly punishment phase. Our main result provides a rationale for the existence of a strong positive relationship …

L'educazione tra generi e generazioni
2020
Il contributo analizza il legame in educazione tra identità di genere e generazioni, intendendo con quest'ultimo termine sia l'aspetto generazionale sia quello generativo che troviamo all'interno di ogni storia familiare. La riflessione avviata approda all'idea di un'educazione che dovrebbe rendere consapevoli della reciprocità tra maschile e femminile come fondamento della comprensione della propria storia familiare e della costruzione del proprio sé. In quest'ultimo punto, il tema del genere si intreccia fortemente con quello delle generazioni, e quindi con la propria storia familiare, in cui il maschile e il femminile avranno assunto significati specifici, non sempre segnati dalla recipr…
Mother and offspring fitness in an insect with maternal care: phenotypic trade-offs between egg number, egg mass and egg care
2014
Background Oviparous females have three main options to increase their reproductive success: investing into egg number, egg mass and/or egg care. Although allocating resources to either of these three components is known to shape offspring number and size, potential trade-offs among them may have key impacts on maternal and offspring fitness. Here, we tested the occurrence of phenotypic trade-offs between egg number, egg mass and maternal expenditure on egg care in the European earwig, Forficula auricularia, an insect with pre- and post-hatching forms of maternal care. In particular, we used a series of laboratory observations and experiments to investigate whether these three components no…
The use of results of spectral analysis of synchronous generator output voltage for technical diagnostics.
2006
The method of technical diagnostics of ship diesel engine-generator installations is offered. Spectral-power diagnostic parameters of the synchronous generator voltage and currents are used. The electric machine in this case is the multipurpose sensor of diagnostic parameters. On these parameters it is possible to judge quality of course of working processes in diesel engine cylinder, its technical condition. This method is applicable to piston compressor installations with the electric drive.
