The publication of the book Capital in the Twenty-First Century by Piketty helped to increase the debate about the prospects of the evolution of income and wealth inequality in this century. One of the main controversies is about the effects to the income and wealth inequalities of a decrease in...

We incorporate a variable elasticity of substitution production function into an overlapping generations model à la Diamond (1965). We show that a certain parameter in the production function is a source of biased technical change is a crucial determinant of the economy's growth dynamics. For...

This paper reviews potential output from a euro area perspective by summarising the developments according to international institutions and assessing the impact of the crisis. The paper also considers the methodological basis for potential output estimates, and the high degree of uncertainty...

The severe impacts of the global financial crisis had effects on all world. However, in Sudan scientists and researchers were greatly shocked because of the governmental camouflaging on their real effects on the economy. Minister of National Economy and Finance denied the effects on the Sudanese...

We may be on the cusp of a 'second industrial revolution' based on advances in artificialintelligence and robotics. We analyze the implications for inequality and output, usinga model with two assumptions: 'robot' capital is distinct from traditional capital in itsdegree of substitutability with...

This paper studies the impact of U.S. immigration barriers on global knowledge production. We present four key findings. First, among Nobel Prize winners and Fields Medalists, migrants to the U.S. play a central role in the global knowledge network—representing 20-33% of the frontier knowledge...

We discuss regional disparities in economic performance and living standards. We first set out some key facts, and provide a conceptual framework to help analyze whether such disparities are efficient, or instead reflect market and/or policy failures. We examine whether policy attempts to reduce...

The reaction of hours worked to technology shocks represents a key controversy between RBC and New Keynesian explanations of the business cycle. It sparked a large empirical literature with contrasting results. We demonstrate that, with a more general and data coherent supply and production...

The aim of this paper is to take a structured approach at estimating the coefficients of factors explaining movements of the labour share across countries. In particular, we focus on proper dynamic specification and test the validity of the homogeneity assumption of slope coefficients frequently...
