Collusion at the extensive margin [PDF]
International Journal of Industrial Organization, 2010 Abstract We augment the multi-market collusion model of Bernheim and Whinston (1990) by allowing for firm entry into, and exit from, individual markets. We show that this gives rise to a new mechanism by which a cartel can sustain a collusive agreement: Collusion at the extensive margin whereby firms collude by avoiding entry into each other's ...

Extensions of marginalized graph kernels
Twenty-first international conference on Machine learning - ICML '04, 2004Positive definite kernels between labeled graphs have recently been proposed. They enable the application of kernel methods, such as support vector machines, to the analysis and classification of graphs, for example, chemical compounds. These graph kernels are obtained by marginalizing a kernel between paths with respect to a random walk model on the ...

How Big is the Gig? The Extensive Margin, The Intensive Margin, and The Hidden Margin
Labour Economics, 2021Abstract This paper presents survey measures of informal "gig" work in the United States along both the extensive and intensive margins. Focusing on labor-intensive activities, the total amount of gig work performed by U.S. household heads in 2015 was equivalent to 3.77 million full-time jobs, of which 20 percent came from online work.

Extensive Margins in Agriculture
OECD Food, Agriculture and Fisheries Papers, 2009This paper examines whether the growth in agricultural trade of 69 countries between 1996 and 2006 has taken place at the intensive or the extensive margin. The paper addresses the questions: have agricultural exports during this period expanded more through the intensive margin (more exports of established goods to traditional partners) or through the

Full Conglomerability, Continuity and Marginal Extension
2016We investigate fully conglomerable coherent lower previsions in the sense of Walley, and some particular cases of interest: envelopes of fully conglomerable linear previsions, envelopes of countably additive linear previsions and fully disintegrable linear previsions.

The role of extensive and intensive margins and export growth [PDF]
Journal of Development Economics, 2011 Abstract We investigate and compare countries' export growth based on their performance at the extensive and intensive export margins. Our empirical approach is motivated by an extension to the Melitz (2003) model of heterogeneous firms in which exporters are subject to a one-time sunk cost and also a per-period fixed cost. With imperfect information

On extensions of marginals for decision-making
2005An extension of a set of marginals (small-dimensional distributions) is a joint probability distribution that is a ”good” representative of the knowledge (about the problem area) contained in the marginals. ”Good” means with respect to the subsequent decision-making for which the extension is needed.
