Consumers often benefit from increased competition in differentiated product settings. In this paper we consider consumer benefits from increased competition in a differentiated product setting: the spread of non-traditional retail outlets. In this paper we estimate consumer benefits from...

This paper examines how the level and dispersion of self-reported happiness has evolved over the period 1972-2006. While there has been no increase in aggregate happiness, inequality in happiness has fallen substantially since the 1970s. There have been large changes in the level of happiness...

This paper provides a comprehensive survey of seven aspects of rising inequality that are usually discussed separately: changes in labor's share of income; inequality at the bottom of the income distribution, including labor mobility; skill-biased technical change; inequality among high incomes;...

Economists tend to assume that redistributive transfers increase equity but cause a loss in efficiency, the so-called 'leaky bucket' effect. This paper explores situations where efficiency losses are small or where equity and efficiency might even complement each other. A simple model identifies...

The rise in American inequality has been exaggerated both in magnitude and timing. Commentators lament the large gap between the growth rates of real median household income and of private sector productivity. This paper shows that a conceptually consistent measure of this growth gap over 1979...

Many scholars have argued that once "basic needs" have been met, higher income is no longer associated with higher in subjective well-being. We assess the validity of this claim in comparisons of both rich and poor countries, and also of rich and poor people within a country. Analyzing multiple...

We show that, without strong auxiliary assumptions, it is impossible to rank groups by average happiness using survey data with a few potential responses. The categories represent intervals along some continuous distribution. The implied CDFs of these distributions will (almost) always cross...

This paper argues that measures of life satisfaction, now being collected annually by the Gallup World Poll in more than 130 countries, permit a much broader view of the quality and consequences of development than other common measures. While these data show the importance of conventionally...

The "Easterlin paradox" suggests that there is no link between a society's economic development and its average level of happiness. We re-assess this paradox analyzing multiple rich datasets spanning many decades. Using recent data on a broader array of countries, we establish a clear positive...

This paper uses the first three waves of the Gallup World Poll to investigate differences across countries, cultures and regions in the factors linked to life satisfaction, paying special attention to the social context. Our principal findings are: First, using the larger pooled sample, we find...
