THE SPATIAL AND TEMPORAL DIFFUSION OF STYLISTIC INNOVATIONS IN MATERIAL CULTURE
SCHOLNICK, JONATHAN B. - In: Advances in Complex Systems (ACS) 15 (2012) 01, pp. 1150010-1
Many explanations for the sigmoid or S-shaped curves that characterize the diffusion of innovations through time have … underlying social forces that structure diffusion through both space and time. Using historic New England gravestones and their … among consumers can generate both wave-like diffusion patterns through space and lead to the persistence of cultural …

DYNAMIC BEHAVIOR OF A NONLINEAR SINGLE SPECIES DIFFUSIVE SYSTEM
CHEN, FENGDE; CHEN, XIAOXING; SHI, JINLIN - In: Advances in Complex Systems (ACS) 08 (2005) 04, pp. 399-417
In this paper, we consider the following nonlinear single species diffusive system \begin{eqnarray*} \dot{x}_i(t)&=& x_i(t)\left(b_i(t)-\sum_{k=1}^{l_i}a_{ik}(t)(x_i(t))^{\beta_{ik}}\right)\\ && +\,\sum_{j=1}^{n}D_{ij}(t)(x_j(t)-x_i(t)),\quad (i,j=1,2,\ldots,n), \end{eqnarray*} where bi(t),...

DO LANGUAGE CHANGE RATES DEPEND ON POPULATION SIZE?
WICHMANN, SØREN; STAUFFER, DIETRICH; SCHULZE, CHRISTIAN; … - In: Advances in Complex Systems (ACS) 11 (2008) 03, pp. 357-369
An earlier study [24] concluded, based on computer simulations and some inferences from empirical data, that languages will change the more slowly the larger the population gets. We replicate this study using a more complete language model for simulations (the Schulze model combined with a...

BETTER BEING THIRD THAN SECOND IN A SEARCH FOR A MAJORITY OPINION
STAUFFER, DIETRICH - In: Advances in Complex Systems (ACS) 05 (2002) 01, pp. 97-100
Monte Carlo simulations of a Sznajd model show that if a near-consensus is formed out of four initially equally widespread opinions, the one which at intermediate times is second in the number of adherents usually loses out against the third-placed opinion.

Are Consumers Affected by Durable Goods Makers' Financial Distress? The Case of Auto Manufacturers
Hortacsu, Ali - 2010
The financial decisions of durable goods makers can impose spillovers on their consumers. Namely, durable goods provide a consumption stream that frequently depends on services provided by the manufacturer (e.g., warranties, parts, and maintenance). Manufacturer bankruptcy, or even the...

A Model of the Consumption Response to Fiscal Stimulus Payments
Kaplan, Greg - 2011
A wide body of empirical evidence finds that around 25 percent of fiscal stimulus payments (e.g., tax rebates) are spent on nondurable household consumption in the quarter that they are received. To interpret this fact, we develop a structural economic model where households can hold two assets:...

Optimal Policy Instruments for Externality-Producing Durable Goods Under Time Inconsistency
Heutel, Garth - 2011
When consumers exhibit present bias and are time-inconsistent, the standard solution to market failures caused by externalities--Pigouvian pricing--is suboptimal. I investigate policies aimed at externalities for time-inconsistent consumers. Welfare-maximizing policy in this case includes an...

Guns, Latrines, and Land Reform : Private Expectations and Public Policy
Kremer, Michael - 2016
Dynamically and statically optimal Pigouvian subsidies on durables will differ in a growing economy. For durables with positive externalities, such as sanitation, statically optimal subsidies will typically grow. However, in a dynamic game, governments can most cheaply induce optimal purchasing...
