In a sample of Tanzanian formal sector workers the vast majority have a desire for working longer hours in their main job, and supplement earnings through participation in informal production. Determinants of participation in informal production are examined through estimation of structural-form Logit models. A new way around the problem of measuring incomes from informal production is suggeste...

We analyze a macroeconomic model of monopolistic competition in which consumers earn unequal incomes. When preferences are non-homothetic, the distribution of income affects equilibrium mark-ups and equilibrium product diversity.

OBJECTIVE This paper aims to contrast the demographic correlates of leisure and transportation walking. METHODS Using data from the 2005 National Health Interview Survey (n=31,482), this paper reports on the prevalence of transportation walking and leisure walking for U.S. adults and examines the variation in prevalence across different socio-demographic groups. The prevalence of transportati...

Optical scan voting systems are ubiquitous. Unfortunately, optical scan technology is vulnerable to failures that can result in miscounted votes and lost confidence. While manual counts may be able to detect these failures, counting all the ballots by hand is in many situations impractical and prohibitively expensive. In this paper, we present a novel approach for examining a large set of ballo...

The Busse–Heikes dynamical model is described in terms of relaxational and non-relaxational dynamics. Within this dynamical picture a diverging alternating period is calculated in a reduced dynamics given by a time-dependent Hamiltonian with decreasing energy. A mean period is calculated which results from noise stabilization of a mean energy. The consideration of spatial-dependent amplitudes l...

This paper examines the motivations for the construction of consumer decision tools (CDTs). CDTs are Web-based decision support systems aimed at improving the quality of consumer decisions. CDTs are useful for high involvement choices, such as car or university programme selection, where the consumer is strongly affected by the outcome. Firms will supply CDTs only when they desire informed, mut...

Previous research has found that iconic gestures (i.e., gestures that depict the actions, motions or shapes of entities) identify referents that are also lexically specified in the co-occurring speech produced by proficient speakers. This study examines whether concrete deictic gestures (i.e., gestures that point to physical entities) bear a different kind of relation to speech, and whether thi...

This paper investigates bloatware bundling and product pricing decisions of a monopolistic firm when consumers can remove the bloatware from their electronic devices after purchase. We show conditions under which it is optimal for the firm not to bundle bloatware with their products. Furthermore, we show that even if the firm can make it harder for consumers to remove bloatware, the firm is not...

The Busse-Heikes dynamical model is described in terms of relaxational and nonre-laxational dynamics. Within this dynamical picture a diverging alternating period is calculated in a reduced dynamics given by a time-dependent Hamiltonian with decreasing energy. A mean period is calculated which results from noise stabilization of a mean energy. The consideration of spatial-dependent amplitudes l...
