Despite its sophistication, Early Modern Japan, 1600-1868, had among the lowest real wage levels ever recorded, half of those in pre-industrial England. This paper resolves this puzzle by considering the more equal landownership distribution in Japan relative to Europe. Due to institutional...

In the assessment of the cost of public funds, there is a pervasive economic fallacy, which is frequently repeated by officials in both the private and public sectors as well as in academia: since the cost of borrowing is higher for a private sector firm than it is for a public sector firm, the...

In view of training increasingly complex learning architectures, we establish a nonsmooth implicit function theorem with an operational calculus. Our result applies to most practical problems (i.e., definable problems) provided that a nonsmooth form of the classical invertibility condition is...

We study how consumers’ environmental awareness (CEA) affects the design of environmental policy in the e-commerce sector. We also examine if there is a need for regulation requiring delivery operators to reveal their emissions. We consider a model with two retailers who sell a differentiated...

Superspreading has been suggested to be a major driver of overall transmission in the case of SARS-CoV-2. It is therefore important to statistically investigate the tail features of superspreading events (SSEs) to better understand virus propagation and control. Our extreme value analysis of...

Based on bike-sharing systems (BSS) data in Toulouse and Lyon, this study examines the impact of COVID-19 on relevant variables to BSS usage. Our findings indicate significant changes in longer travel distances, which would be explained by users who use the BSS at peak hours. Also, there is...

This paper studies zero-sum splitting games with finite sets of states. Players dynamically choose a pair of martingales {pt,qt}t, in order to control a terminal payoff u(p∞,q∞). A firstpartintroduces the notion of “Mertens-Zamir transform” of a real-valued matrix and use it to approximate the...

Reaping the full benefits from cross-border interconnection typically requires reinforcement of national networks. When the relevant parts of the networks are complements, a lack of coordination between national transmission system operators typically results in investment below optimal levels in...

Violence affects households’ preferences, perceptions and constraints regarding fertility choices. What happens when violence ends? Using administrative data from Colombia, we find that the end of a long internal conflict differentially increased fertility by 2.6 percent in areas exposed to...
