We explore the relationships between subjective well-being and income, as seen across individuals within a given country, between countries in a given year, and as a country grows through time. We show that richer individuals in a given country are more satisfied with their lives than are poorer...

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...

This paper throws new light on the relationship between income and democracy. Using data for 162 countries over 1960-2018, we show that the causal relationship between political and economic development is U-shaped: "intermediate" political regimes significantly lead to inferior economic...

In recent years, the private sector has been recognized as a key engine of Africa's economic development. Yet, the most simple and fundamental question remains unanswered: how large is the African private sector? We present novel estimates of the size of the private sector in 50 African...

The Easterlin Paradox states that at a point in time happiness varies directly with income, both among and within nations, but over time the long-term growth rates of happiness and income are not significantly related. The principal reason for the contradiction is social comparison. At a point...

Or Paradox Regained? The answer is Paradox Regained. New data confirm that for countries worldwide long-term trends in happiness and real GDP per capita are not significantly positively related. The principal reason that Paradox critics reach a different conclusion, aside from problems of data...

The striking thing about the happiness-income paradox is that over the long-term - usually a period of 10 y or more - happiness does not increase as a country's income rises. Heretofore the evidence for this was limited to developed countries. This article presents evidence that the long term...

The paper assesses the global effects of brain drain on developing economies and quantifies the relative sizes of various static and dynamic impacts. By constructing a unified generic framework characterized by overlapping-generations dynamics and calibrated to real data, this study incorporates...

This paper examines fungibility as a possible explanation for the "missing link" between foreign aid and economic growth. The composition of aid plays a crucial role in determining the composition of government spending and, consequently, the magnitude of fungibility and its impact on growth....

This paper examines micro-level channels of how financial development can affect macroeconomic outcomes like the level of income and export intensity. We investigate theoretically and empirically how financial constraints affect a firm's innovation and export activities, using unique firm survey...
