The question of whether two drugs - namely alcohol and tobacco - are used as complements or substitutes is of crucial interest if side-effects of anti-smoking policies are considered. Numerous papers have empirically addressed this issue by estimating demand systems for alcohol and tobacco and...

We hypothesize that hog production can be characterized by complementarities between newtechnologies, worker skills and farms size. Such production processes are consistent withKremer’s (1993) O-ring production theory in which a single mistake in any one of severalcomplementary tasks in a...

Instituting an initial round of centralized wage setting before an ultimate round ofdecentralized wage bargaining may raise actually raise employment. A general multiequilibriummodel is presented with strategic complementarities in theimplementation of a new technology through aggregate demand...

A model of English auction that allows jump bidding is proposed. When twoobjects are sold separately via such English auctions, I construct an equilibrium suchthat bidders signal via jump bids, thereby forming rational expectations of the priceswithout relying on any central mediator. This...

Our context involves Cournot oligopolists producing NM products at constant marginal costs when preferences are quasi-linear. We identify relationships between second moments of unit costs and second moments of firm-level production. For example, a larger variance in unit costs of a product...

We consider a two-sided buyers & sellers' market with indiviseble goods. Agents may trade many units of any of the items available. Previous research, documenting the case ofunit-flow trades, showed that the existence of substitutability or complementarity colligations between goods. These...

Welfare in a two-product Cournot oligopoly is shown to increase (decrease) with an increase incorrelation between unit costs when the outputs complement (substitute) in demand. A morequalified correlation structure is required for the result to apply in a three-product Cournotoligopoly when...
