Aplysia californica interneurone L10 forms a set of presynaptic connections with many postsynaptic 'follower' cells in the abdominal ganglion. These followers do not connect back to L10. The present study tests whether the direction and sign of these connections are obligatory and are reconstructed when neuronal processes regenerate in vitro. L10 was co-cultured with one of six different follow...

If an aggregative game satisfies the generalized Hahn conditions, then there exists a unique Nash equilibrium which may not be interior and is globally asymptotically stable under two alternative continuous adjustment processes with non-negativity constraints. JEL Classification Numbers: C72, D43, L13.

Suppose that infinitesimal firms have identical variable costs but there is heterogeneity in their fixed costs. Regardless of the ordering of entry and exit, fixed costs will be minimized for a given industry size. Journal of Economic Literature Classifications: L11 & L13

Abstract Background Hepatic burden is a significant confounder in the assessment of impact primary tumour resection metastatic small bowel neuroendocrine tumours (SI-NET). For SI-NET hepatic >10% disease replacement or > 5 metastases are known prognostic markers, though nomograms and scores do not adequately account for this. Most trials when assessing survival difference between ...

This paper quantifies employer market power in US manufacturing and how it has changed over time. Using administrative data, we estimate plant-level markdowns—the ratio between a plant’s marginal revenue product of labor its wage. We find most plants operate monopsonistic environment, with an average markdown 1.53, implying worker earning only 65 cents on the dollar generated. To investigate lo...

This paper analyzes the impact of intermediary concentration on allocation revenue in online platforms. We study sponsored search documenting how advertisers increasingly bid through a handful specialized intermediaries. enhances automated bidding and data pooling, but lessens competition whenever represents competing advertisers. Using nearly 40 million Google keyword auctions, we first apply ...

We consider a Cournot oligopoly setting in which consumers have an intrinsic preference for variety, while unit production costs of firms increase with the number of goods they produce. This environment exhibits a general under-provision of variety with respect to social welfare. JEL Classification Numbers: C70, L13, L20

We investigate the issue of strategic substitutability/complementarity in a Cournot differential game with sticky prices. We show that first order conditions do not produce instantaneous best reply functions. However, we identify negatively sloped reaction functions in steady state, with the open-loop best reply being flatter than its closed-loop counterpart. JEL classification: C73, D43, D92, ...
