Although there is ample empirical evidence that congestion charges can effectively reduce traffic congestion and its detrimental effects, this instrument has only been implemented in a handful European cities. On the basis of a randomized information experiment that was embedded in a survey...

Electric mobility and renewable energy play key roles in the global energy transition. In this context, vehicle- to-grid technology, which enables bidirectional energy ŕow between electric vehicles and the grid, could make electric vehicles usable as energy storage units, thus supporting grid...

Hidden “junk” fees have the potential to distort competition, creating high costs to consumers. However, regulating them can lead to adverse effects, especially in complex markets with intermediaries where they are most prevalent. To explore the equilibrium adjustments of regulating hidden...

Between 2012 and 2024, Poland-once a laggard in cashless payments among EU countries-underwent a profound transformation. The per capita number of cashless transactions at physical points of sale increased more than eightfold, rising from approximately 30 to over 250 per year, surpassing the EU...

This paper investigates the impact of price transparency on equilibrium prices and fees by considering a policy change implemented by Airbnb that affected the transparency of cleaning fees for IP addresses from the European Union (EU). Using a difference-in-differences approach, we find a...

This technical background paper evaluates the progress of African nations in establishing effective fiscal frameworks for digital infrastructure across the continent. Through a comprehensive comparative analysis of legislative, tax, and regulatory policies in over 20 African countries, the...

Domestic abuse is a pervasive global problem. Here we analyze two approaches to reducing violent DA recidivism. One involves charging the perpetrator with a crime; the other provides protective services to the victim on the basis of a formal risk assessment carried out by the police. We use...

This study investigates airport congestion pricing and capacity investment with cost recovery consideration. Two countries’ airports are interlinked and served by each country’s home carrier. Our global welfare maximization shows that when per-passenger subsidies are not feasible under...

Domestic abuse is a pervasive global problem. Here we analyze two approaches to reducing violent DA recidivism. One involves charging the perpetrator with a crime; the other provides protective services to the victim on the basis of a formal risk assessment carried out by the police. We use...

This paper considers the design of efficient Distribution Use of System (DUoS) tariffs for the Irish electricity distribution network. We calculate indicative costreflective 'Coasian' tariff for residential, commercial and industrial consumers. Under a cost-reflective 'Coasian' structure, non...

The aim of this contribution is to confirm or dispute the hypothesis that the new system of charges for municipal waste management in the Czech Republic is suitable for both taxpayers and municipalities. To achieve this aim, the article critically describes the old and new methods of communal...

The active mutual fund equilibrium model developed by Berk and Green (2004) predicts that fees should not matter for investors’ mutual fund choices. We examine how fees influence demand for active mutual funds by analyzing time variation in funds’ fees. Since investors should not pay "alpha...

Royalty payment has been under heated debate in both the traditional art market and the newly emerged non-fungible tokens (NFTs) markets. In this paper, we investigate the role of royalty payments in the trading market with creators and buyers and explore how NFT platforms should design royalty...

We pose the problem of managing the interstate as an optimal capital stock problem and define user cost as the charge per vehicle mile travelled that rationalizes observed investments in lane miles and pavement quality. We find that user cost is the sum of the opportunity cost of lane miles,...

The CFTC has recently licensed a commercial prediction market to operate in the US. Previous theoretical work has not incorporated that prediction markets charge fees. We examine the impact of fees by introducing them to a model in which the market price equals the true probability when there...

In models of certification possible restrictions on the nature of the fee structures are commonly analyzed. We show that they are irrelevant for the certifier's ability to maximize profits and trade efficiency. Our results establish that certification schemes involve two substitutable...

Restrictions on certifiers' fee structures are irrelevant for maximizing their profits and trade efficiency, and for the implementability of (monotone) distributions of rents. The irrelevance results exploit that certification schemes involve two substitutable dimensions-the fee structure and...
