Run or Hide? Fixed and Moving Targets
We examine the time it takes for a random walk to hit an adversarial moving target. This problem was introduced by Aldous and Fill as the “cat and mouse” game. They conjectured that for every graph hitting an optimally moving target takes as long in expectation as hitting an optimally placed stationary target. We show this conjecture is false by presenting an instance of a graph where it takes ...
متن کاملTranscultural research run amok or Arctic hysteria?
I would like to begin my commentary with thanks to Dr. Edward Foulks, for his effort at self-disclosure and critique in this journal. From one perspective, Foulks presents us with an anatomy of a failure. It is my impression that he has written this review to inform American Indian and Alaska Native communities as well as mental health researchers in their future collaborations. He allows us to...
متن کاملLong - run trends or short - run fluctuations What establishes the correlation between oil and food prices ?
In this paper we use the frequency domain Granger causality test of Breitung/Candelon (2006) to analyse short and long-run causality between energy prices and prices of food commodities. We find that the oil price Granger causes all the considered food prices. However, when controlling for business cycle fluctuations this link exists especially at low frequencies. Thus, short-run phenomena like...
متن کاملThe long - run weight of communism or the weight of long - run history ?
This study provides evidence that culture understood as values and beliefs moves very slowly. Despite massive institutional change, values and beliefs in transition countries have not changed much over the last 20 years. Evidence suggests that culture is affected by the long run historical past, in particular the participation in empires for over 100 years. Current institutional evolutions in t...
متن کاملDirect or indirect tax instruments for redistribution: short-run versus long-run
Optimal tax theory has shown that, under simple assumptions, indirect taxation such as production subsidies, tariffs, or differentiated commodity taxation, are sub-optimal and that redistribution should be achieved solely with the direct income tax. However, these important results of optimal tax theory, namely production efficiency and uniform commodity taxation under nonlinear income taxation...
