Invariant Coordinate Selection (ICS) is a multivariate technique that relies on the simultaneous diagonalization of two scatter matrices. It serves various purposes, including its use as a dimension reduction tool prior to clustering or outlier detection. Unlike methods such as Principal Component...

We study mergers between firms operating in data-connected markets: the data generated as a byproduct of the activity on market A can be used by firms operating on market B. The effects of such a merger depend on whether data trade among independent firms is possible, and on whether data use...

We formalize inter-sectoral knowledge diffusion in a standard fully endogenous Schumpeterian growth model. Each sector is simultaneously sending and receiving knowledge; thereby, to produce new knowledge, the research and development activity of each sector draws from a pool of knowledge which...

This paper studies how Mobile Network Operator (MNO) impacts traditional banks’ coverage decision in a model of vertical and horizontal differentiation with asymmetric transportation costs. The competitive pressure triggered by MNOs entry on traditional banking sector leads to prices decrease and...

Agents often make choices based on expectations about uncertain attributes, yet the information used to form these expectations is typically unobserved by researchers. We develop two methods to estimate discrete choice models in which agents form expectations using heterogeneous and unobserved...

This paper examines a principal–agent model without transfers in which a Principal mandates actions and conducts costly inspections. The Prin-cipal trades off the benefit of mandating her preferred actions against the Agent’s participation, information rents, and inspection costs. I examine which...

We study transaction fees applied by marketplace platforms where sellers (e.g., app developers) adopt freemium pricing. An ad valorem transaction fee reduces quality distortions introduced by the price-discriminating seller, thereby increasing consumer surplus. Moreover, a small fee increases...

We study agents that provide Cash-In/Cash-Out (CICO) services to mobile money consumers. A moral hazard friction constrains these agents’ ability to hold liquid reserves, which creates an endogenous cost for operators of ensuring reliable CICO services. Interoperability that allows agents to...
