The relationship between public expenditure and aggregate income has long been debated in economic literature. According to Wagner, expenditure is an endogenous factor or an outcome. On the other hand, Keynes considered public expenditure as an exogenous factor to be used as a policy instrument...

Market growth is driven by product innovation. Beyond functional satiation the marginal utility of product performance and variety decreases. We argue that social comparisons underlying innovation diffusion results in consumer motivations for upward assimilation toward the behavior of better...

The paper examines in the laboratory how risk-taking situations are affected by the conditions of observing other's choices (observer) and being observed by others (source). By extending Yechiam et al.'s (2008) experimental design to the domain of gains we find that observers are more probable...

While this is typically ignored, the properties of the stochastic process followed by aggregate consumption affect the estimates of the costs of fluctuations. This paper pursues two approaches to modelling aggregate consumption dynamics and to measuring how much society dislikes fluctuations,...
