Ipoacusia neurosensoriale causata da scoppio di petardo. Aspetti medico-legali
2013
Gli Autori illustrano un caso di ipoacusia neurosensoriale permanente rilevata all’orecchio di sinistra con un deficit uditivo pantonale pari a 70 dB. La lesione è stata determinata dallo scoppio di un petardo, lanciato in vicinanza della persona lesa. Vengono valutati i risvolti medico-legali in ambito penale e civile. Per quanto concerne la sfera penalistica l’ipotesi di reato è quella di lesione personale grave, in ragione dell’indebolimento permanente della funzione uditiva; relativamente al contesto civilistico, si pone particolare attenzione alla questione inerente al risarcimento cui il soggetto danneggiante è obbligato, considerando in particolar modo gli effetti che la lesione ha d…
Les effets macroéconomiques sur la productivité et les prix de vastes réformes structurelles sur les marchés des biens et du travail
2015
La présente analyse vise à caractériser les effets « directs » et « indirects » des régulations sur le marché des biens ainsi que les effets des régulations sur le marché du travail, sur la productivité et sur les prix. L’analyse est empirique et réalisée via des estimations sur un panel de quatorze pays sur la période 1987-2007, et quand cela est possible sur des donnés sectorielles (treize secteurs manufacturiers et cinq secteurs des services et réseaux). Au terme de ces estimations, il est possible de caractériser les effets de la mise en oeuvre de réformes structurelles. Les réformes structurelles consistent ici en une baisse des indicateurs de régulations sur les marchés des biens et d…
Performance measures for hierarchical organizations: Frontier analysis as a decision support tool
2009
We extend the standard frontier efficiency models (data envelopment analysis [DEA] and stochastic frontier analysis [SFA]) by allowing the “decision making units” (DMUs) whose performances are assessed to consist of two different levels within hierarchical organizations. Generally, the lower level unit is responsible for “operations;” while higher level units are assumed to make “strategic” decisions. Our primary contribution in this paper is thus to extend the use of frontier efficiency models to assess each level performance with relevant technical and allocative inefficiency measures. We illustrate our approach using DEA applied to data from a sample of 1,585 branches of a major French b…
Competing Against Simulated Equilibrium Price Dispersions: An Experiment on Internet-Assisted Search Markets
2005
In a four-treatment experiment, we test some of the hypotheses in García-Gallego et al. (2004) concerning competition among a number of firms of which some (or all) are indexed by a price-comparison engine facilitating buyers’ search process. In this paper, we isolate individual behavior from noise due to other players’ actions and learning, facing each subject with simulated rivals whose prices are extracted from mixed strategy equilibrium distributions. We find systematic deviations from both theoretical distributions and previous data obtained in sessions where all players were human. Specifically, departures of experimental data from the corresponding theoretical predictions are enhance…
Delegated agency in multiproduct oligopolies with indivisible goods
2010
This paper focuses on oligopolistic markets in which indivisible goods are sold by multiproduct firms to a continuum of homogeneous buyers, with measure normalized to one, who have preferences over bundles of products. Our analysis contributes to the literature on delegated agency games with direct externalities and complete information, extending the insights by Berheim and Whinston (1986, a , b) to markets with indivisibilities. By analyzing a kind of extended contract schedules - mixed bundling prices - that discriminate on exclusivity, the paper shows that efficient equilibria always exist in such settings. There may also exist inefficient equilibria in which the agent chooses a subopti…
To switch or not to switch - Can individual lending do better in microfinance than group lending?
2011
These days it has been witnessed, that banks other individual loans instead of group loans and develop products based on individual liability in developing coun- tries. In order to study this surprising turn, we expand the conventional approach on decision making of individuals. A social prestige function is introduced that re- ‡ects the non-monetary impacts of group membership on the individual and on her decisions. If a borrower possesses more than a critical level of wealth, it is optimal for her to switch to individual borrowing. From a welfare perspective, a mixture of individual and group loans is desirable. However, the average borrower switches from group to individual lending too …
Some preliminary but troubling evidence on group credits in microfinance programmes
2010
Group lending programs are said to be the key factor of success of microÂ…nance. They are said to reduce information asymmetries in credit contracts and to increase repayment rates. Despite that, in recent years more and more individual credits without collateral are given, even if there is no mutual monitoring of the borrowers. We use basic descriptive statistics on individual- and group panel data, which we construct out of a World Bank data set. We provide Â…rst evidence that individuals that are not participating in group credits accumulate wealth more quickly than participants of group credit programs.
ANALYZING THE EUROPEAN MARKET OF INTEREST RATE SWAP INDICES
2012
The interest rate risk is the most important risk that derives from the OTC transactions, taking into consideration both the notional amounts and the market value of the financial derivatives that relies on interest rate contracts. Open positions on interest rate derivatives represents more than 75% of the OTC market. In the European banking market interest rate swaps prices are strongly dependent on the interbank interest rates. In this paper we want to analyze the behavior of the Eoniaswap indices and their impact on the interest rate swaps between banks.
Are Energy Market Integrations a Green Light for FDI?
2015
This paper studies the effect of energy market integration (EMI) on foreign direct investment (FDI). EMIs diminish energy uncertainty and price volatility in the host country and affect FDI through two channels: first, by harmonizing energy prices and, second, by reducing price dispersion. FDI may, as a result, increase both within and outside the EMI area, through energy stability mechanisms and price mechanisms, respectively. An empirical application on a global dataset including bilateral FDI data, during 2003-2012, using the gravity equation, shows that the integration of Portugal and Spain's electricity market in 2007 increased the amount of FDI's participants. Additionally, a positive…
QUALITY AND PRICES OF INTRA-EUROPEAN TRADE OF FOOD-INDUSTRY PRODUCTS
2000
The completion of the European Single Market should bring out an exploitation of comparative advantages in production and trade. It is usually assumed that, given the predominance of intraeuropean trade flows in the global import figures of the European Union, efficiency gains from trade creation could be potentially important. However, the analysis of the effects of the Single Market on trade specialisation with a greater degree of accuracy requires trade quality indicators to be available. This paper uses the theory of index numbers to establish the relative quality levels of the food industry shipments to the European Internal Market from European Union member countries. It is found a po…
