Social capital, government expenditures, and growth

We present a tractable stochastic endogenous growth model that explains how social capital influences economic development. In our model, social capital increases citizens' awareness of government activity. Hence, it alleviates the electoral incentives to under- invest in education, whose returns are delayed and less visible to voters. In equilibrium, higher social capital raises the average output growth rate and reduces its volatility by increasing public investment in education while making its returns higher and less variable. Our theory also predicts that a more unequal distribution of social capital reduces public education expenditures. We provide suggestive cross-country evidence consistent with these predictions.Social Capital, Education Expenditures, Economic Growth, Elections, Government Expenditures, Imperfect Information

Hydrogen gas embrittlement and the disc pressure test

A disc pressure test has been used to study the influenced of a hydrogen gas environment on the mechanical properties of three high strength superalloys, Inconel 718, L-605 and A-286, in static and dynamic conditions. The influence of the hydrogen pressure, loading rate, temperature, mechanical and thermal fatigue has investigated. The permeation characteristics of Inconel 718 have been determined in collaboration with the French AEC. The results complemented by a fractographic study are consistent either with a stress-sorption or with an internal embrittlement type of mechanism

What makes hot beverage vending machine cups eco-friendly? A research into consumer views and preferences

Purpose: This study aims to gain a first explorative view on what intrinsic/extrinsic attributes a generic cup for hot beverage should possess to be perceived as eco-friendly, and how some attributes of a hot beverage could influence consumers’ purchase decision and willingness to pay (WTP) for that beverage dispensed by vending machines (VMs). Design/methodology/approach: A questionnaire was developed in 2021 and sent to all students of an Italian university campus. For the first goal, students were asked to assign a score to some eco-friendly intrinsic/extrinsic attributes using a five-point Likert scale. For the second aim, a choice experiment with six scenarios was developed. Findings: Both intrinsic and extrinsic attributes play a key role in shaping students’ opinions and preferences. Results indicate that students are attracted by the idea of a cup that communicates its environmental properties through corresponding labels and information, and it is made by materials that guarantee biodegradability, recyclability or reusability. Originality/value: The research represents the first academic attempt to provide a first consumers’ viewpoint on the importance of eco-friendly attributes of cups for hot beverages able to influence consumers’ perceptions and consumption choices of hot beverages dispensed by VMs

Ab initio parametrised model of strain-dependent solubility of H in alpha-iron

The calculated effects of interstitial hydrogen on the elastic properties of alpha-iron from our earlier work are used to describe the H interactions with homogeneous strain fields using ab initio methods. In particular we calculate the H solublility in Fe subject to hydrostatic, uniaxial, and shear strain. For comparison, these interactions are parametrised successfully using a simple model with parameters entirely derived from ab initio methods. The results are used to predict the solubility of H in spatially-varying elastic strain fields, representative of realistic dislocations outside their core. We find a strong directional dependence of the H-dislocation interaction, leading to strong attraction of H by the axial strain components of edge dislocations and by screw dislocations oriented along the critical slip direction. We further find a H concentration enhancement around dislocation cores, consistent with experimental observations.Comment: part 2/2 from splitting of 1009.3784 (first part was 1102.0187), minor changes from previous version

Labor Market Attitudes and Experienced Political Institutions

In this paper I first present a novel fact: women who have experienced democratic institutions during their adolescence are more likely to participate in the labor market, keeping constant the country, age and many other confounding factors. I then present evidence suggesting that discriminatory attitudes may be a channel for such a finding. Other explanations receive less support from the data

Three Essays in Political Economy and Public Finance

Chapter 1 evaluates the effect of relaxing fiscal rules on policy outcomes applying a quasi-experimental research design. We implement a "difference-in-discontinuities" design by combining the before/after with the discontinuous policy variation generated by the implementation of the Domestic Stability Pact on Italian municipalities between 1999 and 2004. Our estimates show that relaxing fiscal rules triggers a substantial deficit bias, captured by a shift from a balanced budget to a deficit that amounts to 2 percent of the total budget. The deficit comes primarily from reduced revenues as unconstrained municipalities have lower real estate and income tax rates. The impact is larger if the mayor can run for reelection, the number of political parties seated in the city council is higher, voters are older, the performance of the mayor in providing public good is lower, and cities are characterized by historical deficit, consistently with models on the political economy of fiscal adjustment. Chapter 2 studies the electoral response to the Ghost Buildings program, a nationwide anti tax evasion policy in Italy, which used innovative monitoring technologies to target buildings hidden from tax authorities. The difference-in-differences identification strategy exploits both variation across towns in the ex ante program scope to increase enforcement as well as administrative data on actual building registrations. After the policy, local incumbents experience an increase in their reelection likelihood. These political returns are higher in areas with higher speed of public good provision and with lower tax evasion tolerance, implying complementarity among enforcement policies, government efficiency, and the underlying tax culture. Chapter 3 examines reasons for cross-country variation in maternity leave provision. We show that the less tolerant a society is of gender-based discrimination, the longer the maternity leave it will optimally mandate. We collected new data on the number of gender-differentiated personal pronouns across languages to capture societies' attitudes toward gender-based discrimination. We first confirm, using within-country language variation, that our linguistic measure is correlated with attitudes toward gender-based discrimination. Then, using cross-country data on length of maternity leave we find a strong correlation between our measure of attitudes and the length of maternity leave.Economic
