We have adapted to RNA molecules the ligation-mediated polymerase chain reaction (LMPCR) procedure of genomic sequencing [Mueller, P. R. & Wold, B. (1989) Science 246, 780-786]. This new procedure, the reverse ligation-mediated PCR (RLPCR), is sufficiently sensitive to allow "in vivo" footprinting of minor RNA species. It is based on the ligation of an RNA linker of known sequence to every 5' e...

Bertrand competition

Bertrand competition is a model of competition used in economics, named after Joseph Louis François Bertrand (1822-1900). Specifically, it is a model of price competition between duopoly firms which results in each charging the price that would be charged under perfect competition, known as marginal cost pricing. The model has the following assumptions: There are at least two firms producing ho...

Thank You, Edward. Merci, Louis.

We study oligopoly price competition between multiproduct firms, firms whose products interact in the profit function. Specifically, we focus on the impact of intra-firm product interactions on the level of equilibrium profits. This impact is divided into two effects: a direct effect and a strategic effect (i.e., through the competitors’ actions). We derive conditions such that the strategic ef...
