This paper is part of the Copenhagen Consensus process, which aims to assess and evaluate the opportunities available to address the ten largest challenges facing the world. One of these ten challenges is the “lack of education.” This paper will define “lack of education,” in terms of...

This article compares the statutory ad valorem tariff rates (official rates) with the ratio of tariff revenues to import values (collected rates) for Jamaica, Kenya, and Pakistan. It identifies four general features of the tariff codes, considers whether these features apply to all developing...

The historical path of gross domestic product (GDP) per capita in the United States is, except for the interlude of the Great Depression, well characterized by reasonably stable exponential trend growth with modest cyclical deviations: graphically, it is a modestly sloping, slightly bumpy hill....

Many oil, mineral, and plantation crop--based economies experienced a substantial deceleration in growth following the commodity boom and bust of the 1970s and early 1980s. This article illustrates how countries dependent on point source natural resources (those extracted from a narrow...

Many oil, mineral, and plantation crop-based economies experienced a substantial deceleration of growth since the commodity boom and bust of the 1970s and early 1980s. Rodrik (1999) has demonstrated that the magnitude of a country's growth deceleration since the 1970s is a function of both the...

Standard economic analysis suggests that when the budget for redistribution is fixed, income transfers should be targeted to (i.e. means-tested for) those most in need. However, both political scientists and economists long have recognized the possibility that targeting might undermine political...

The prevailing aid orthodoxy works well enough in stable environments, but is ill-equipped to navigate contexts of volatility and fragility. The orthodox approach is adept at solving straightforward technical or logistical problems (paving roads, building

We propose and implement a new technique for measuring the total magnitude of a growth episode: the change in output per capita resulting from one structural break in the trend growth of output (acceleration or deceleration) to the next. The magnitude of the gain or loss from a growth episode...

Two key unanswered questions in theories of growth are (a) why some countries successfully initiate episodes of rapid growth while others suffer extended stagnation and (b) why some countries are able to sustain growth episodes over many decades of rapid (or steady) growth while other growth...
