Security of supply and the energy transition : the households' perspective investigated through a discrete choice model with latent classes

Motz, Alessandra

In: Energy economics, 2021, vol. 97, no. May, p. 16 p

A consumer-centric, market-based approach to the security of electricity supply has been recognized as increasingly important in the context of the energy transition. Nonetheless, there is no clear-cut evidence regarding the drivers of consumer preferences toward security and the perceived trade-offs between security and sustainability. Using stated preference data, we develop a discrete...

Consumer acceptance of the energy transition in Switzerland : the role of attitudes explained through a hybrid discrete choice model

Motz, Alessandra

In: Energy policy, 2021, vol. 151, no. April, p. 15 p

While several countries progress in the energy transition, the social acceptance of new infrastructures becomes increasingly important. We focus on market acceptance, and study the preferences of Swiss households with respect to selected energy sources used for electricity generation. By applying a hybrid discrete choice model with latent variables on stated preference data, we assess...

Gold and bubbles: an impossible binomial? : a review of historical and current evidence

Beretta, Edoardo ; Peluso, Stefano

In: Applied economics letters, 2021, p. 5 p

Gold has a far-reaching history of ‘safe haven’ or ‘anchor of stability’. However, the epitome of precious metals has recently deviated from its historical price trend. Fluctuations and volatility have increased too. We argue that gold is not subject to bubbles (due to its scarcity in nature), although its price is. By means of a logical-analytical macroeconomic approach combined with...

Space-time multilevel Monte Carlo methods and their application to cardiac electrophysiology

Ben Bader, Seif ; Benedusi, Pietro ; Quaglino, Alessio ; Zulian, Patrick ; Krause, Rolf

In: Journal of computational physics, 2021, vol. 433, p. 17 p

We present a novel approach aimed at high-performance uncertainty quantification for time-dependent problems governed by partial differential equations. In particular, we consider input uncertainties described by a Karhunen-Loève expansion and compute statistics of high-dimensional quantities-of-interest, such as the cardiac activation potential. Our methodology relies on a close integration...

Fighting the spread of Covid-19 : was the Swiss lockdown worth it?

Gatti, Nicolò ; Retali, Beatrice

The implementation of a lockdown to control the Covid-19 pandemic has led to a strong debate in several countries. This makes it crucial to shed light on the actual benefits of such kind of policy. To this purpose, we focus on the Swiss lockdown during the first wave of Covid-19 infections and estimate the number of potentially saved lives. To predict the number of deaths in absence of any...

Robots and nonparticipation in the US : where have all the workers gone?

Lerch, Benjamin

I analyze the impact of one of the leading automation technologies of the last decades – industrial robots – on the declining labor force participation in the US. Exploiting exogenous variation in the adoption of robots across local labor markets and over time, I find that, on average, one additional robot drives two workers out of the labor force. The massive increase in robot adoption...

Earthquakes, grants and public expenditure : how municipalities respond to natural disasters

Masiero, Giuliano ; Santarossa, Michael

In: Journal of regional science, 2020, vol. 60, no. 3, p. 481-516

We analyze the response of municipalities to the occurrence of natural disasters in terms of spending behavior, use of upper tier transfers and recovery, using balance sheet data of about 8000 Italian municipalities for the period 2000-2015 and the universe of earthquakes events. We find evidence of increasing expenditure for about 12 years after the shocks, with asymmetric responses between...

Gender-based price discrimination in the annuity market : evidence from Chile

Bello, Piera

This paper studies gender-based price discrimination in the annuity market. The dataset consists of transaction-level data on the universe of individuals accessing the Chilean annuity market in the 2004-2017 period. It exploits the fact that, in Chile, individuals can access the annuity market through three different channels: an independent financial advisor, a sales agent at a company, or...

The environmental cost and the accident externality of driving : evidence from the Swiss franc’s appreciation

Bello, Piera

This study investigates the effects of driving on air quality and road safety by exploiting exogenous variation in traffic flows associated with the Swiss franc’s appreciation. During the Swiss franc’s appreciation, the volume of cars crossing the Swiss-Italian border rose considerably– the higher purchasing power of Swiss francs in the Euro area induced more Italian workers to cross the...

Asset prices and demand shocks

Barbon, Andrea ; Franzoni, Francesco (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2020 ; 2020ECO002.

My dissertation consists of three chapters, each of which focuses on a different area of research in asset pricing. The first chapter deals with the informational role of brokerage firms during fire sales in the equity market. The second chapter exploits the ETF program by the bank of Japan as a quasi-natural experiment to measure the slope of the equity demand curve. The last chapter presents...
