Though the environmental Kuznets curve (EKC) was originally developed to model the ambient concentrations of pollutants, most subsequent applications focused on pollution emissions. Yet, previous research suggests that it is more likely that economic growth could eventually reduce the...

GMM estimation of autoregressive panel data equations in error-ridden variables when the noise has memory, is considered. The impact of variation in the memory length in signal and noise spread and in the degree of individual heterogeneity are discussed with respect to finite sample bias, using...

We present a model of endogenous firm growth with R&D investment and stochastic innovation as the engines of growth. The model for firm growth is a partial equilibrium model drawing on the quality ladder models in the macro growth literature, but also on the literature on patent races and the...

This paper, based on the introductory remarks made at the two-day conference on "The State of the Economy, the State of the World," is an idiosyncratic stocktaking of the trajectory of economics from Adam Smith to contemporary times, with special attention to the rise of development economics....

Changing population age structures are shaping the trajectories of development in many countries, bringing opportunities and challenges. While aging has been a matter of concern for upper-middle and high-income economies, rapid population growth is set to continue in the poorest countries over...

This paper examines the role of changes in sectoral productivity gaps over time in accounting for growth realized by countries over the past few decades. To quantify the productivity impact of the sectoral gaps, a simple model of resource allocation is developed in which the gaps arise due to...

Brazil approaches its 2018 election with an economy that is gradually recovering from the deepest recession in its recent economic history. However, for many Brazilians, the recovery has not yet translated into new and better jobs, or rising incomes. This book explores the drivers of future...

Global growth is projected to be slightly faster in 2020 than the post-crisis low registered last year. While growth could be stronger if reduced trade tensions lead to a sustained reduction in uncertainty, the balance of risks to the outlook is to the downside. Growth in emerging market and...

A strong and widely acknowledged record of economic success-including a three-and-a-half-fold increase in per capita income since 1994--places Rwanda among the world's fastest--growing economies. Traumatic memories of the 1994 genocide are gradually fading, as associations begin to take a more...
