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...

Should the central bank prevent 'excessive' asset price dynamics or should it wait until the boom spontaneously turns into a crash and intervene only afterwards? The debate over this issue goes back at least to the exchange between Bernanke-Gertler (BG) and Cecchetti but has not settled yet. In...

Building on the framework put forward by Delli Gatti et al. 2011, in this paper we present and discuss a Macroeconomic Agent-Based Model with Capital and Credit (hereafter CC-MABM). The novelty of this model with respect to the previous framework consists in the introduction of capital goods...

We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest in non-liquid assets. Market clearing takes place through a tâtonnement process which yields the equilibrium price, while traded quantities are determined by means of a...
