We consider a general framework of optimal mechanism design under adverse selection and ambiguity about the type distribution of agents. We prove the existence of optimal mechanisms under minimal assumptions on the contract space and prove that centralized contracting implemented via mechanisms...

Infra-monthly time series have increasingly appeared on the radar of official statistics in recent years, mostly as a consequence of a general digital transformation process and the outbreak of the COVID-19 pandemic in 2020. Many of those series are seasonal and thus in need for seasonal...

Infra-monthly economic time series have become increasingly popular in official statistics in recent years. This evolution has been largely fostered by official statistics’ digital transformation during the last decade. The COVID-19 pandemic outbreak in 2020 has added fuel to the fire as many...

The COVID-19 outbreak in 2020 has fostered in many countries the development of new weekly economic indices for the timely tracking of pandemic-related turmoils and other forms of rapid economic changes. Such indices often utilise information from daily and weekly economic time series that...

We solve the equilibrium market structure in a labor market where vacancies and unemployed workers can meet either in an intermediated market where wages are determined by take-it-orleave- it offers, or in a directed search market where firms post wages. By using an intermediary agents avoid the...

We study the effects of different tax reporting mechanisms in experi-mental double auction markets in the laboratory. The sales tax is paidby the seller, and we compare market outcomes in a no-tax conditionto cases where (i) tax evasion is impossible, (ii) taxes can be evaded butthere is an...

I examine a rational expectations model of buyers and capacity con-strained sellers, where traders can choose between a cluster and a searchmarket. Sellers choose a market and post a price, and then buyerschoose which market to visit. There is a pure strategy equilibriumwhere all agents are in...

We experimentally examine the effects of price competition in markets for experience goods where sellers can build up reputations for quality. We compare price competition to monopolistic markets and markets where prices are exogenously fixed (somewhere between the endogenous oligopoly and...
