摘要

意大利摘要:从2014年1月到2020年9月,意大利银行印制钞票的全球设备效率指数(OEE)每月系列。oee表示一个工业站点的运行程度,它衡量的是在给定时间范围内达到标准的生产量与计划生产的生产量之比的百分比。这项工作突出了自2018年3月印刷厂恢复工作以来,该指数的进展情况,以及在卫生紧急情况的最新阶段开展工作的弹性。计量经济学检验将该指数在随后重组的谈判最激烈阶段的下跌幅度量化为10个百分点,从而量化了行业组织文献中已证明的一种现象。英语摘要:在这份文件中,我们为意大利银行的银行生产设备编制了一系列月刊的有效设备指数,从2014年1月到2020年9月。OEE指数确定了实际生产时间的制造份额,衡量的是实际标准合规生产量在分配时间间隔内实现的比率,以及同一时期的计划产出。2018年3月,随着反应的激增,工厂的增长达到了顶峰,就像在当前的健康紧急情况下生产的弹性一样。根据计量经济学家的调查结果,我们在与工会进行谈判时,在指数上划掉了大约10个百分点,这导致了一段时间的混乱。这一证据提供了经验证据,以支持工业组织中众所周知的模式的存在。

Un indice OEE per la stampa delle banconote in Banca d’Italia (An OEE index for the Bank of Italy’s Banknote Production Plant)
Italian Abstract: Il lavoro presenta una serie mensile dell’indice di Overall Equipment Effectiveness (OEE) per la stampa delle banconote in Banca d’Italia, dal gennaio 2014 al settembre 2020. L’OEE esprime il grado di funzionamento di un sito industriale, misurando in percentuale il rapporto tra il volume di produzione conforme agli standard realizzato in un dato intervallo di tempo e quanto si era pianificato di produrre. Il lavoro evidenzia i progressi registrati nell’indice dopo il riassetto della stamperia a partire dal marzo 2018, nonché la resilienza nello svolgimento dell’attività nella fase più recente di emergenza sanitaria. Tramite verifiche econometriche si misura in circa 10 punti percentuali la flessione dell’indice nella fase più intensa delle trattative che poi ebbero ad esito la riorganizzazione, quantificando così un fenomeno ben attestato nella letteratura di organizzazione industriale.

English Abstract: In this paper, we present a monthly series of the Overall Equipment Effectiveness (OEE) index for the Bank of Italy’s banknote production plant, from January 2014 to September 2020. The OEE index identifies the share of manufacturing time that is truly productive, measured as the ratio between the actual standard-compliant production volume achieved within a given time interval and the planned output for the same period. The paper highlights the increase in the plant’s OEE after the rollout of the reorganization in March 2018, as well as the resilience of the production even during the ongoing health emergency. Based on the results of an econometric exercise, we measure a fall of about 10 percentage points in the index during the negotiations with the trade unions that led to the reorganization, a time of heightened uncertainty. This evidence provides empirical support to the existence of a pattern well known in the industrial organization literature.
