The COVID-19 pandemic has increased the risk of participating in public events, among them elections. We assess whether the voter turnout in the 2020 local government elections in Italy was affected by the COVID-19 pandemic. We do so by exploiting the variation among municipalities in the intensity of the COVID-19 outbreak as measured by the mortality rate among the elderly. We find that a 1 percentage point increase in the elderly mortality rate decreased the voter turnout by 0.5 percentage points, with no gender differences in the behavioural response. The effect was especially strong in densely populated municipalities. We do not detect statistically significant heterogeneous effects between the North and the South or among different levels of autonomy from the central government.

Title: Unemployment scarring effects: a symposium on empirical literature
Authors:  Mattia Filomena
This article reviews the empirical literature on unemployment scarring effects. Our goal is twofold: on the one hand, to present an overview of empirical evidence relating to the impact of unemployment spells on subsequent labour market career; on the other hand, to provide a review of the econometric strategies mainly adopted to estimate the causal impact of such unemployment episodes. Focusing on a final sample of 63 papers, the empirical evidence appears
homogeneous in highlighting significant and persistent wage losses and strong state dependence.

Title: Risk and Strategic Complementarities: Banks Behavior, Supervision and Macroprudential Policies
Authors:  T. Carraro, Edoardo Gaffeo, Marco Gallegati
In this paper we present a model where frictions in the supervision process may set the stage for strategic complementarities among banks. We derive
the conditions for strategic complementarities in the behavior of banks in a banking system in which the supervisory authority has a budget constraint
on the resources to allocate for monitoring, and supervision is costly for banks. In such a framework, the goal of macroprudential policies consists in
simultaneously restraining the incentive of banks in extending risky loans, without forcing the system towards a corner solution where all or none of
the banks provide credit. We point out that the countercyclical buer is a proper tool to reduce the number of banks issuing a higher amount of credit
during booms, while a loan-support-program can increase the number of banks issuing higher credit during downturns.

Title: To divorce or not to divorce: is this a property tax problem?
Authors:  Raffaella Santolini
The decision to end a marriage may depend on economic reasons such as more advantageous tax breaks obtained through a divorce. The paper examines the role played by property tax in influencing decisions of marital separation and divorce in Italian municipalities over the years 2001-2007.
Empirical analysis shows that there is a significant increase in divorces and marital separations as the difference between the municipal secondary and primary home tax rate increases. Women are more inclined than men to separate and divorce when the municipal property tax rates differences become larger.

Title: Search for Profits and Business Fluctuations: How Banks' Behaviour Explain Cycles?
Authors:  Emanuele Ciola, Edoardo Gaffeo, Mauro Gallegati
This paper develops and estimates a macroeconomic model of real-financial markets interactions in which the behaviour of banks generates endogenous business cycles. We do so in the context of a computational agent-based framework, where the channelling of funds from depositors to investors occurring through intermediaries nformation and matching frictions.
Since banks compete in both deposit and credit markets, the whole dynamic is driven by endogenous fluctuations in their profits. In particular, we assume that intermediaries adopt a simple learning process, which consists of copying the strategy of the most profitable competitors while setting their interest rates.
Accordingly, the emergence of strategic complementarity - mainly due to the accumulation of information capital - leads to periods of sustained growth followed by sharp recessions in the simulated economy.

Title: Microchip bags and waste sorting
Authors:  Matteo Picchio
We evaluate the effectiveness of placing microchips on the bags for the curbside collection in reducing the unsorted urban solid waste and increasing the fraction recycled. The microchip allows the waste collection company to identify the users that left the bags on the curb and check whether they properly sorted the waste. Our study is carried out in the Italian province of Macerata (Marche, Italy), where the bag microchips were introduced only in some municipalities in 2013. Exploiting monthly information on waste collection and natural experiment methods, we find that, two years after the programme start, the bag microchip increased the fraction recycled by 3-4.5 percentage points and decreased the monthly unsorted waste by 1-2 kilograms per capita.

What is the impact of immigration on the product mix of the receiving economy? To answer this question we exploit variation in the presence of immigrants across Italian provinces within the period 2003-2011. We find that immigration changes the manufacturing output composition of Italian provinces in favour of less capital intensive products, without affecting the total amount of manufacturing production. This result is based on a 2SLS strategy resting on the settlement of immigrants in the pre-sample period and is in line with the predictions of standard trade models concerning the role of factor growth on product specialisation. More specifically, immigrants sustain and deepen Italy's revealed comparative advantages in labour intensive goods. We thus add to the existing studies finding within-industry adjustments of factor usage in production rather than between-industry output adjustments in response to immigration flows. When searching for the underlying mechanisms driving our result, we discover that a larger share of immigrants promotes the local reshoring of labour intensive
productions and fosters the creation of new firms in labour intensive industries.
