Under very general conditions, the best predictor of any random variable’s observed time series is not its mean but its median. Hence, if we aim to model a variable with a skewed (a.k.a. asymmetric) probability distribution, ...
Although long-distance interaction dates back to Prehistory, the scale and complexity of exchange during the Urban Revolution are unparalleled. How did early urban societies organize transcontinental trade without modern ...
In a political-agency model, an incumbent can initiate a restrictive policy in response to a crisis state of the world. Both the opposition and the citizen value the incumbent's policy matching the state; however, they ...
This paper studies the main patterns and trends observed in primary education in Catalonia between 1860 and 1930. The information gathered from official education statistics makes it possible to track several primary ...
The use of high-stakes assessments has become widespread in educational systems. While they can potentially boost student achievement, they may also increase anxiety levels, which could negatively affect their academic ...
Europe’s rapidly ageing population poses critical challenges for long-term care (LTC) systems, particularly guaranteeing equitable access. While socio-economic disparities in LTC utilisation are well documented, inequalities ...
Over the past three decades, many countries have adopted fiscal rules. This paper studies their impact on economic growth using an overlapping generations model with endogenous growth, where the government imposes both a ...
We theoretically investigate whether AI developers or AI operators should be liable for the harm the AI systems may cause when they hallucinate. We find that the optimal liability framework may vary over time, with the ...
This paper studies the fiscal multiplier in Bolivia considering key characteristics of the country and compares the results obtained for Bolivia with the fiscal multipliers estimated for Latin American countries. The main ...
We propose new point valued solutions for global games. We explore the implications of weakening some of the properties used by Gilboa and Lehrer (1991) in their characterization result. Our main contributions are the ...
When a financial network collapses, how should mutual obligations among all agents be cleared? We study this problem taking an axiomatic approach and provide the first characterization of the family of rules based on the ...
In this paper, we investigate how competition among NGOs to attract donations affects the behavior of NGOs' employees. NGOs hire workers to undertake development projects, which are horizontally and vertically differentiated. ...
This paper builds a spatial model of trade with supply-chain links to try to understand the effect of economic links and policies on the spread of the Covid-19 pandemic during the first wave across NUTS2 UK regions. We ...
This paper documents the existence of significant gender gaps in STEM occupations in Costa Rica, El Salvador, and Mexico and estimates the aggregate costs associated with these gaps in Mexico. For Mexico we calibrate and ...
We consider priority-based school choice problems with farsighted students. We show that a singleton set consisting of the matching obtained from the Top Trading Cycles (TTC) mechanism is a farsighted stable set. However, ...
Governments can support the green transition through green public procurement. Despite its strategic importance, the impact of this policy on firms remains unclear. Using US data, this paper provides the first empirical ...
Institutional common ownership of firm pairs in the same industry increases the likelihood of a preexisting social connection among their CEOs. We establish this relationship using a quasinatural experiment that exploits ...
This paper investigates the contribution of services trade to the variation of global income generation for the period of 2000 to 2014, applying a structural decomposition analysis in a global multi-regional input-output ...
This paper shows what the main inflation macroeconomics drivers in Spain are. Even if there has been a less than two-digit inflation in the last three decades, it can be emphasized the fact that the inflation rate has ...
Individuals are embedded in a network of relationships and they can be victims, bystanders, or perpetrators of bullying and harassment. Each individual decides noncooperatively how much effort to exert in preventing ...
