Waves in Guinness
We describe a simple model of a bubbly two-phase flow which is able to explain why waves propagate downward when a pint of Guinness is poured, and also how the waves are generated. Our theory involves a physically based regularization of the basic equations of the two-phase flow, using interphasic pressure difference and virtual mass terms, together with bulk or eddy viscosity terms. We show th...
متن کاملDo Housing Bubbles Affect Consumption?
Standard optimzing models of consumption postulate that consumption is a function of wealth and implicitly assume that wealth is comprised of assets whose market price coincides with the fundamental price, defined as the expected present value of future dividends. We use a simple theoretical framework to show that when the market price deviates from the fundamental price, consumption behavior w...
متن کاملDo Housing Bubbles Generate Fiscal Bubbles? Evidence From California Cities∗
This paper examines the effects of the most recent U.S. housing bubble on the fiscal policy of California cities. We use an instrumental variables approach that helps isolate fiscal consequences of house price appreciation by taking advantage of the influence of local topological constraints on the elasticity of house prices with respect to interest rates. Our analysis generates three main find...
متن کاملSource-sink partitioning. Do we need Münch?
The simulation of phloem translocation by the Münch theory commonly uses resistances from sources to sinks: the resistances are therefore regarded as important in partitioning. Although resistance is generally a set constant, it is in fact strongly affected by viscosity, and thus the concentration of the transported solute. In this paper, the model of partitioning proposed by Minchin et al. was...
