"A common hypothesis regarding the distribution of income is that it tends to become more unequal in the initial and middle stages of economic development, in part because of demographic changes. However, previous studies of the effect of demographic changes on income distribution are not based on the underlying micro determinants of the income components." In the present paper, "the micro de...

The 2012 Albert Lasker Special Achievement Award in Medical Science will be shared by Donald Brown and Tom Maniatis for their scientific work leading to the purification and study of single genes by physical and molecular biological methodologies. Brown and Maniatis are also recognized for their extraordinary commitment and generosity in promoting the careers of young scientists. The impact of ...

The issue addressed in this paper is the optimal taxation of incomes earned tn the home economy, and of incomes earned abroad, when people can migrate. As a preliminary, the optimal taxation of home incomes when there is migration and no taxation of foreign incomes, is discussed. Then in a more general setting, we deal with optimal taxation of different kinds of labour when another kind of labo...

This study investigates whether personal taxes are related to asset valuations. The effective tax rate of investment income fluctuated considerably since federal income taxes were introduced. The main result of the paper demonstrates that there is an economically and statistically significant relationship between asset valuations and personal tax rates. Stock valuations tend to be higher when t...

A number of recent papers argue that financial frictions arising from limited commitment problems can explain large cross-country income differences. We argue that different micro financial underpinnings have potentially very different implications at both the macro and the micro level. To this end, we develop a general equilibrium framework that encompasses different regimes of frictions, and ...

AIM The aim was to examine risk factors for hearing impairment among Hispanic/Latino adults with diabetes. METHODS Findings are based on 3384 participants aged 18-76 years with diagnosed or previously undetected diabetes who completed audiometric testing as part of the Hispanic Community Health Study/Study of Latinos. We defined hearing impairment as the pure-tone average (PTA) >25 decibels h...

Empirical studies of supplier-induced demand in health care have mostly concentrated on the analysis of physician behaviour. In this article, the focus is on the economic determinants of physiotherapist behaviour in The Netherlands. It is shown that relative prices work as strong incentives to alter the mix of services supplied, conform to the model of revenue maximization under a production co...

where the migrant’s consumption, cm, depends on w, the migrant’s earnings in the host country, less r, the amount remitted to the household at home. The altruism weight attached to the household at home is given by ah. Consumption of the household at home is given by ch = c(y + r) where y is the earnings of household members at home. A migrant chooses a level of r to maximize his utility, and t...
