This paper studies whether market structure affects algorithmic recommendations in dominant platforms. We focus on the dual role of Amazon.com as a platform owner and retailer. We find that products sold by Amazon receive substantially more "Frequently Bought Together" recommendations across...

We study the signaling role of prices in a context of salient thinking. Consumer attention can be directed towards the product attribute - quality or price - that stands out in the market. Products' quality is not directly observed by consumers. Our analysis provides two main results. First, we...

Public support is crucial for the energy system’s transition towards renewable energy (RE). This paper examines how spatial proximity to wind turbines (WTs) affects public support for RE using two measures – local preferences for RE electricity tariffs based on more than 35 million search queries...

Beyond the ethical principles of self-regulation adopted by some digital companies, this workshop focuses on the construction of an artificial intelligence law. An AI law appears following a sector-based approach depending on the degree of risk. A transversal approach of accountability.can also be...

We study a model of retrospective search in which an agent—a researcher, an online shopper, or a politician—tracks the value of a product. Discoveries beget discoveries and their observations are correlated over time, which we model using a Brownian motion. The agent decides both how ambitiously,...

We propose a new method to estimate continuous-time job search models. Our approach is based on an adaptation of the conditional choice probability estimation methods to a continuous-time job search environment. To do so, the proposed framework incorporates preference shocks into the search...

We empirically investigate the impact of multi-homing in two-sided markets. First, we build a micro-founded structural econometric model, which encompasses demand for differentiated products and allows for multi-homing on both sides of the market. We then use an original dataset on the Italian...
