We develop a positive theory of pricing car access (by parking fees or cordon tolls) to downtown commercial districts. The model accounts for the special interests of downtown retailers and competing superstores at the edge of the city, and studies how lobbying by both groups shapes the...

This paper studies the political economy of cordon tolls in a monocentric city consisting of three zones: center, mid-city and suburbs. The cordon toll may give rise to several interrelated conflicts: between residents within and outside the cordon, between car and public transport users,...

To enforce regulations, governments often delegate power to public officials. However, officials may have incentives to abuse their discretionary power and engage in bribery or extortion. Efforts to monitor and curb such abuses have inspired interest in using new communication technologies to...

We develop a spatial equilibrium model to study the political economy of pricing downtown parking space when special interest groups (retailers, local residents) lobby the city government. Parking fees penalize downtown retailers, but benefit suburban stores that provide free parking. We show...

We investigate the relation between Net Neutrality regulation and Internet fragmentation. We model a two-sided market, where Content Providers (CPs) and consumers interact through Internet Service Providers (ISPs), and CPs sell consumers' attention to advertisers. Under Net Neutrality, a...

We study the relation between ad networks, consumer privacy and the online advertising market. We consider two publishers that can outsource their ad inventories to an ad network, in a market where consumers and advertisers endogenously multi-home. Differently from publishers, the ad network...

Ownership takeovers often follow complex strategies where the control of the target firm is acquired through a sequence of independent contracts. Based on this observation, we develop a novel theoretical model wherein the acquiring firm decides on the number of steps towards the full ownership...

We study a platform's design of membership and transaction fees when sellers compete and buyers cannot observe the prices and features of goods without incurring search costs. The platform alleviates sellers' competition by charging them transaction fees that increase with sales revenue, and...

We use linked employer-employee data to investigate the job satisfaction effect of unionisation in Britain. We depart from previous studies by developing a model that simultaneously controls for the endogeneity of union membership and union recognition. We show that a negative association...

This paper argues that, for a given overall level of labour income taxation, a more progressive tax schedule reduces the unemployment rate and increases the employment rate. From a theoretical point of view, higher progressivity induces a wage-moderation effect and increases overall employment...
