In addition to self-production and individual disconnection from the national grid, the ongoing decentralization of the electricity market increasingly relies on energy-sharing mechanisms such as energy communities (ECs). This paper presents a parsimonious model that captures key features of the...

Multi-sector variants of standard gravity models typically predict much larger gains from trade than their one-sector counterparts. This paper explores to what extent this result is due to the relevant cross-sector variation observed in trade elasticity and to what extent it is instead an...

Although outsourcing vs. vertical integration is generally treated as a binary choice in international trade literature, firm-level data reveal that inputs can be imported both within and across firms' boundaries, even within narrowly defined industries from the same host country. This paper...

This paper proposes a generalized framework for the analysis of collusion in Bertrand oligopoly markets with possibly differentiated products and asymmetric cost structures. We first study how product differentiation interacts with the intensity of collusion (i.e., the cartel's proximity to the...
