Policy And Planning

Chapter 3 demonstrates that DIY urban designers are largely motivated by failings they perceive in urban policy and planning. Placing them in this context is essential for interpreting the phenomenon. While do-it-yourselfers respond to the problems they see in creative ways, their individualistic tactics of doing so introduce problems of their own. The chapter focuses on bus stops to consider the lack of sidewalk seating in many cities, the privatization of street furniture, and concerns with local service provision. In trying to correct problems they see, do-it-yourselfers always impart their own personal and cultural values, and some DIY alterations can be selfish and anti-social in impact. The chapter interrogates DIY urbanism in the context of the “neoliberalized” city, arguing that even as the practices aim to counter the ill effects of market-driven planning, they can also reinforce an individualistic, undemocratic logic in placemaking.

Calendar Dates

We derive a partial integro differential equation (PIDE) which relates the price of a calendar spread to the prices of butterfly spreads and the functions describing the evolution of the process. These evolution functions are the forward local variance rate and a new concept called the forward local default arrival rate. We then specialize to the case where the only jump which can occur reduces the underlying stock price by a fixed fraction of its pre-jump value. This is a standard assumption when valuing an option written on a stock which can default. We discuss novel strategies for calibrating to a term and strike structure of European options prices. In particular using a few calendar dates, we derive closed form expressions for both the local variance and the local default arrival rate.

AbstractThe time-dependent solutions of an infinite set of differential-difference equations arising from queueing theory and models of ‘living’ polymer are expressed in terms of modified Bessel functions. Explicit solutions are available for constant values of a parameter describing the arrival rate or monomer concentration; for time-dependent parameter a formal solution is obtained in terms of a function which satisfies a Volterra type integral equation of the second kind. These results are used as the basis of a numerical method of solving the infinite set of differential equations when the time-dependent parameter itself satisfies a differential equation.

Server System

We present the first class of perfect sampling (also known as exact simulation) algorithms for the steady-state distribution of non-Markovian loss systems. We use a variation of dominated coupling from the past. We first simulate a stationary infinite server system backwards in time and analyze the running time in heavy traffic. In particular, we are able to simulate stationary renewal marked point processes in unbounded regions. We then use the infinite server system as an upper bound process to simulate the loss system. The running time analysis of our perfect sampling algorithm for loss systems is performed in the quality-driven (QD) and the quality-and-efficiency-driven regimes. In both cases, we show that our algorithm achieves subexponential complexity as both the number of servers and the arrival rate increase. Moreover, in the QD regime, our algorithm achieves a nearly optimal rate of complexity.
