ReQwip : business plan and go-to-market strategy
textThe nature of this Report is to outline the proposed business opportunity for reQwip -- an online marketplace for buying, selling and renting sports equipment -- and the go-to-market strategy for this young startup. reQwip is an Austin, Texas-based technology company founded by students and alumni of The University of Texas at Austin for the purpuse of creating a mobile, peer-to-peer (P2P) marketplace for buying, selling and renting new and used sports equipment. ReQwip is launching its minimum viable product (MVP) in Spring 2014. The MVP is a liquid marketplace focused specifically on buying and selling new and used cycling and triathlon gear in Austin,TX and greater Central Texas. This MVP is our gateway into a sporting goods industry worth 54 billion in the United States, of which $1-3 billion is used gear sales in the U.S.AdvertisingBusiness Administratio
Distributional Preferences, Reciprocity-Like Behavior, and Efficiency in Bilateral Exchange
Under what conditions do distributional preferences, such as altruism or a concern for fair outcomes, generate efficient trade? I analyze theoretically a simple bilateral exchange game: each player sequentially takes an action that reduces his own material payoff but increases the other player’s. Each player’s preferences may depend on both his/her own material payoff and the other player’s. I identify two key properties of the second-mover’s preferences: indifference curves kinked around “fair” material-payoff distributions, and materials payoffs entering preferences as “normal goods.” Either property can drive reciprocity-like behavior and generate a Pareto efficient outcome
An Information-Theoretic Analysis of Thompson Sampling
We provide an information-theoretic analysis of Thompson sampling that
applies across a broad range of online optimization problems in which a
decision-maker must learn from partial feedback. This analysis inherits the
simplicity and elegance of information theory and leads to regret bounds that
scale with the entropy of the optimal-action distribution. This strengthens
preexisting results and yields new insight into how information improves
performance
Phases of New Physics in the CMB
Fluctuations in the cosmic neutrino background are known to produce a phase
shift in the acoustic peaks of the cosmic microwave background. It is through
the sensitivity to this effect that the recent CMB data has provided a robust
detection of free-streaming neutrinos. In this paper, we revisit the phase
shift of the CMB anisotropy spectrum as a probe of new physics. The phase shift
is particularly interesting because its physical origin is strongly constrained
by the analytic properties of the Green's function of the gravitational
potential. For adiabatic fluctuations, a phase shift requires modes that
propagate faster than the speed of fluctuations in the photon-baryon plasma.
This possibility is realized by free-streaming relativistic particles, such as
neutrinos or other forms of dark radiation. Alternatively, a phase shift can
arise from isocurvature fluctuations. We present simple models to illustrate
each of these effects. We then provide observational constraints from the
Planck temperature and polarization data on additional forms of radiation. We
also forecast the capabilities of future CMB Stage IV experiments. Whenever
possible, we give analytic interpretations of our results.Comment: 39 pages, 10 figures, 5 tables; v2: minor corrections, references
