We consider a multicommodity routing problem, where demands are released online and have to be routed in a network during specified time windows. The objective is to minimize a time and load dependent convex cost function of the aggregate arc flow. First, we study the fractional routing variant. We present two online algorithms, called Seq and Seq. Our first main result states that, for cost fu...

We translate between biophysical and economic metrics that characterize the role of energy in the economy. Specifically, using data from the International Energy Agency, we estimate the energy intensity ratio (EIR), a price-based proxy for a power return ratio (PRR ∼ Pout/Pinvested). The EIR is a useful metric, because for most countries and energy commodities, it can indicate the biophysical t...

In the realm of information security, lack of information about other users’ incentives in a network can lead to inefficient security choices and reductions in individuals’ payoffs. We propose, contrast and compare three metrics for measuring the price of uncertainty due to the departure from the payoffoptimal security outcomes under complete information. Per the analogy with other efficiency m...

To evaluate the pharmacoeconomics of three therapeutic schemes in treating anti-tuberluosis therapy -induced liver injury (anti-TB DILI). Methods In the construction of a decision tree model, the efficacy and safety parameters came from the results of the randomized, controlled trial conducted here, the effect parameters were derived from expert advice, and the cost parameters, such as usage ...

In an in…nite horizon model with stochastic costs, moderate in‡ation, costly price adjustment, and optimal price setting, we demonstrate that individual price reductions will be larger but less frequent than price increases. With positive in‡ation, aggregate prices are more responsive to cost increases than to cost decreases, and a calibrated version of the model …ts well the magnitude of downw...

I document that dividend growth and consumption growth comove procyclically. This new stylized fact empirically resolves the “Duffee Puzzle”—stock returns and consumption growth covary procyclically (Duffee, 2005)—but contradicts extant theoretical assumptions in asset pricing models. I then design a new data generating process (DGP) for the joint consumption-dividend dynamics which fits the pr...
