TL;DR: In this article, the authors present three key facts about income and wealth inequality in the long run emerging from my book, Capital in the Twenty-First Century, and seek to sharpen and refocus the discussion about those trends.
Abstract: In this article, I present three key facts about income and wealth inequality in the long run emerging from my book, Capital in the Twenty-First Century, and seek to sharpen and refocus the discussion about those trends. In particular, I clarify the role played by r > g in my analysis of wealth inequality. I also discuss some of the implications for optimal taxation, and the relation between capital-income ratios and capital shares.

TL;DR: Piketty's Capital in the Twenty-First Century as mentioned in this paper is an intellectual tour de force, a triumph of economic history over the theoretical, mathematical modeling that has come to dominate the economics profession in recent years.
Abstract: A New York Times #1 Bestseller An Amazon #1 Bestseller A Wall Street Journal #1 Bestseller A USA Today Bestseller A Sunday Times Bestseller Winner of the Financial Times and McKinsey Business Book of the Year Award Winner of the British Academy Medal Finalist, National Book Critics Circle Award "It seems safe to say that Capital in the Twenty-First Century, the magnum opus of the French economist Thomas Piketty, will be the most important economics book of the year-and maybe of the decade." -Paul Krugman, New York Times "The book aims to revolutionize the way people think about the economic history of the past two centuries. It may well manage the feat." -The Economist "Piketty's Capital in the Twenty-First Century is an intellectual tour de force, a triumph of economic history over the theoretical, mathematical modeling that has come to dominate the economics profession in recent years." -Steven Pearlstein, Washington Post "Piketty has written an extraordinarily important book...In its scale and sweep it brings us back to the founders of political economy." -Martin Wolf, Financial Times "A sweeping account of rising inequality...Piketty has written a book that nobody interested in a defining issue of our era can afford to ignore." -John Cassidy, New Yorker "Stands a fair chance of becoming the most influential work of economics yet published in our young century. It is the most important study of inequality in over fifty years." -Timothy Shenk, The Nation

TL;DR: The authors showed that the large shocks that capital owners experienced during the Great Depression and World War II have had a permanent effect on top capital incomes and argued that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks.
Abstract: This paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the United States using individual tax returns data. Top income and wages shares display a U-shaped pattern over the century. Our series suggest that the large shocks that capital owners experienced during the Great Depression and World War II have had a permanent effect on top capital incomes. We argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks. Top wage shares were flat before World War II, dropped precipitously during the war, and did not start to recover before the late 1960s but are now higher than before World War II. As a result, the working rich have replaced the rentiers at the top of the income distribution.

TL;DR: A recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics as discussed by the authors, and the estimation methods and issues that arise when constructing top income share series, including income definition and comparability over time and across countries, tax avoidance and tax evasion.
Abstract: A recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics. Top incomes represent a small share of the population but a very significant share of total income and total taxes paid. Hence, aggregate economic growth per capita and Gini inequality indexes are sensitive to excluding or including top incomes. We discuss the estimation methods and issues that arise when constructing top income share series, including income definition and comparability over time and across countries, tax avoidance, and tax evasion. We provide a summary of the key empirical findings. Most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks. Top income shares do not recover in the immediate postwar decades. However, over the last thirty years, top income shares have increased substantially in English speaking countries and in India and China but not in continental European countries or Japan. This increase is due in part to an unprecedented surge in top wage incomes. As a result, wage income comprises a larger fraction of top incomes than in the past. Finally, we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open.

TL;DR: This article developed a dynamic general equilibrium model that is intended to help clarify the role of credit market frictions in business fluctuations, from both a qualitative and a quantitative standpoint, and the model is a synthesis of the leading approaches in the literature.
Abstract: This paper develops a dynamic general equilibrium model that is intended to help clarify the role of credit market frictions in business fluctuations, from both a qualitative and a quantitative standpoint. The model is a synthesis of the leading approaches in the literature. In particular, the framework exhibits a financial accelerator,' in that endogenous developments in credit markets work to amplify and propagate shocks to the macroeconomy. In addition, we add several features to the model that are designed to enhance the empirical relevance. First, we incorporate money and price stickiness, which allows us to study how credit market frictions may influence the transmission of monetary policy. In addition, we allow for lags in investment which enables the model to generate both hump-shaped output dynamics and a lead-lag relation between asset prices and investment, as is consistent with the data. Finally, we allow for heterogeneity among firms to capture the fact that borrowers have differential access to capital markets. Under reasonable parametrizations of the model, the financial accelerator has a significant influence on business cycle dynamics.
