The authors compare the two merger control systems currently employed worldwide: a mandatory system based on merger size threshold and a voluntary system with ex-post monitoring and fines. The voluntary system possesses two informational advantages: (i) the enforcement agency employs more...

Global climate change is occurring at an accelerating pace, and the global greenhouse gas (GHG) emissions that are forcing climate change continue to increase. Given the present pace of international actions, it seems unlikely that atmospheric composition can be stabilized at a level that will...

Noting that South Africa may be one of the few African countries that could contribute to mitigating climate change, the authors explore the impact of a carbon tax relative to alternative energy taxes on economic welfare. Using a disaggregate general-equilibrium model of the South African...

Innovation is key to technology adoption and creation, and to explaining the vast differences in productivity across and within countries. Despite the central role of the entrepreneur in the innovation process, data limitations have restricted standard analysis of the determinants of innovation...

While some nations have done better than others, no nation has adequately...

This paper addresses two vital concerns in the debate on adaptation to climate change. First, how can countries prepare to manage the impact of climate-change induced natural disasters? Second, how can countries ensure that they have the governmental institutions required to manage the...

Ethiopia has experienced a historically unprecedented increase in inflation, mainly driven by cereal price inflation, which is among the highest in Sub-Saharan Africa. Using monthly data from the past decade, the authors estimate error correction models to identify the relative importance of...

This paper critically reviews the literature on finance and inequality, highlighting substantive gaps in the literature. Finance plays a crucial role in most theories of persistent inequality. Unsurprisingly, therefore, economic theory provides a rich set of predictions concerning both the...
