Optimal international agreement and restriction on domestic efficiency

Optimal Educational Investment: Domestic Equity and International Competition

How do domestic attributes affect international spillovers of CO2-efficiency?

Although there is evidence that CO2-efficiency enhancing innovations in one country diffuse into other countries to contribute to the goals of climate change mitigation, very little is known about the conditions under which such international spillovers are most likely to take place. Our contribution in the present article seeks to address this gap by examining whether the strength of cross-bor...

Should Audiences Cost? Optimal Domestic Constraints in International Crises∗

We study a model in which a leader’s crisis behavior and the citizens’ responses are both determined optimally. The citizens design incentives with two problems in mind. First, our model identifies a heretofore unnoticed time-consistency problem on the part of leaders who might initiate international crises. Second, we allow the leader and the citizen to disagree about when war is an appropriat...

Scale Efficiency in DEA and DEA-R with Weight Restriction

In data envelopment analyze (DEA) the scale efficiency in the input-oriented CCR model is less than or equal to the scale efficiency in DEA based on the fractional analysis (DEA-R). Also, the scale efficiency in case of multiple inputs and one output and vice versa the scale efficiencies are equal in DEA and DEA-R. In this paper, first, DEA-R model with weight restrictions when there is relativ...

Optimal Agreement Supertrees

An agreement supertree of a collection of unrooted phylogenetic trees {T1, T2, . . . , Tk} with leaf sets L(T1), L(T2), . . . ,L(Tk) is an unrooted tree T with leaf set L(T1) ∪ · · · ∪ L(Tk) such that each tree Ti is an induced subtree of T . In some cases, there may be no possible agreement supertrees of a set of trees, in other cases there may be exponentially many. We present polynomial time...
