We investigate how, in temporary economic hardship, agents change their consumption of health services, and how this depends on whether the service is universally free-of-charge visits to GP's or privately co-financed dental care. We find that own expenditures for dental care decrease. The...

This paper examines methodological issues raised by revealed preference theory in economics: particularly contemporary revealed preference theory. The paper has three goals. First, to make the case that revealed preference theory is a broad research program in choice theory – not a single...

The off-net/on-net price differential in mobile voice observed in many countries is much larger than what can be explained away by standard economic theory. This situation has generated important anticompetitive concerns, leading some authorities to contemplate (and even impose) a ban on such...

The work analyses the writings of Shibani, considering their relevance for contemporary Islamic economics. The novelty of Shibani's earnings model is its integration of Zakat and other social giving in the social welfare function, which makes the consumer utility a multi-dimensional devotional,...

For the last fifty years, countries in Asia and elsewhere witnessed a surge in aggregate savings per capita. Some empirical studies attribute this trend to the increases in life longevity of the populations of these countries. It has been argued that the rise in savings is short-run, eventually...

Income-based as well as most existing multidimensional poverty indices (MPI) assume equal distribution within the household and thus yield a biased assessment of individual poverty and poverty by age or gender. In this paper we first show that the direction of the bias depends on how these...

The empirical literature on the determinants of charities donation income, distinguishing the charitable cause, is small. We extend the literature in several ways. First, we focus on overseas development charities allowing us to give more consideration to the particular characteristics of this...

Studies of inequality often ignore resource allocation within the household. In doing so they miss an important element of the distribution of welfare that can vary dramatically depending on overall environmental and economic factors. Thus, measures of inequality that ignore intrahousehold...

A recent literature has provided empirical evidence that markups are increasing and are heterogeneous across firms. In standard monopolistic competition models, such heterogeneity implies inefficiency even in the presence of free entry. We enrich the standard model of monopolistic competition...

A benchmark result in the political economy of taxation is that majority voting over a linear income tax schedule will result in an inefficiently high tax rate whenever the median voter has a below average income. The present paper examines the role of tax avoidance for this welfare assessment....
