We study the impact of deliberation on intertemporal choices. Using multiple experiments, including a field in Democratic Republic Congo, we show that introduction waiting periods—a policy temporally separates information about choices from themselves—causes substantially less myopic decisions. These results cannot be captured by models exponential discounting nor present bias. Comparing effect...

In this paper we build on the network-based financial accelerator model of Delli Gatti et al. (2010), modelling the firms’ financial structure following the ‘‘dynamic trade-off theory’’, instead of the ‘‘packing order theory’’. Moreover, we allow for multiperiodal debt structure and consider multiple bank-firm links based on a myopic preferred-partner choice. In case of default, we also conside...

This paper studies two-party electoral competition in a setting where no policy is unbeatable. It is shown that if parties take turns in choosing platforms and observe each other’s choices, altering one’s policy platform so as to win is pointless since the other party never accepts an outcome where it is sure to loose. If there is any cost to changing platform, the prediction is that the game e...

With increasing demand for efficient image and video analysis, test-time cost of scene parsing becomes critical for many large-scale or time-sensitive vision applications. We propose a dynamic hierarchical model for anytime scene labeling that allows us to achieve flexible trade-offs between efficiency and accuracy in pixel-level prediction. In particular, our approach incorporates the cost of ...

This paper presents a general class of dynamic stochastic optimization problems we refer to as Stochastic Depletion Problems. A number of challenging dynamic optimization problems of practical interest are stochastic depletion problems. Optimal solutions for such problems are difficult to obtain, both from a pragmatic computational perspective as also from a theoretical perspective. As such, si...

BACKGROUND Peripapillary intrachoroidal cavitation was described as the presence of an asymptomatic, well-circumscribed, yellow-orange, peripapillary lesion at the inferior border of the myopic conus in eyes with high myopia. CASE PRESENTATION A 66-year-old myopic Chinese man was enrolled and his multi-color imaging examination showed a well-circumscribed, caesious, peripapillary lesion coale...

PURPOSE To examine the symmetry of corneal changes following near work in the fellow eyes of non-amblyopic myopic anisometropes. METHODS Thirty-four non-amblyopic, myopic anisometropes (minimum 1 D spherical equivalent anisometropia) had corneal topography measured before and after a controlled near work task. Subjects were positioned in a headrest to minimise head movements and read continuo...

purpose: to evaluate the 8-year results of excimer laser photorefractive keratectomy (prk) for myopia in terms of safety, stability and late complications. methods: of 203 myopic patients who underwent prk with single-step method using nidek ec-5000 excimer laser with 5-6 mm ablation zones at basir eye center, tehran-iran from 1996 to 1998, 179 eyes of 98 patients who completed 8 years of follo...

In cognitive radio (CR) networks, secondary users can be coordinated to perform spectrum sensing so as to detect primary user activities more accurately. However, in a dynamic spectrum environment, more sensing cooperations may induce every secondary user to sense more channels, thus decreasing their transmission time. In this paper, we study this tradeoff by using the theory of partially obser...

Theorem A.1. If Condition 1 holds and K = 0, then, the optimal ordering policy for the finite horizon problem or the infinite horizon discounted profit problem has the following structure. If xt < y ∗, then order up to y∗, and set the sales lever to d∗. Otherwise, do not order. Proof. By Theorem 6.1 of Porteus (2002), it is easy to verify that (y∗,d∗) is the optimal action pair if xt < y∗. If x...
