The paper proposes a technique to test jointly for groupings of unknown size in the cross-sectional dimension of a panel and estimates the parameters of each group, applying it to identifying convergence clubs in income per-capita. The approach uses the predictive density of the data,...

We study the recent evolution of top incomes in Switzerland, analyzing both social security data on labor incomes and tax data on total income. The results show that in the last 20 years, the share of top incomes has risen, and the top 0.01 percent’s share even doubled, putting Switzerland...

During the last three decades, the stock of government debt has increased in most developed countries. During the same period, we also observe a significant liberalization of international financial markets and an increase in income inequality in several industrialized countries. In this paper...

We introduce firm and worker heterogeneity into a model of innovation-driven endogenous growth. Individuals who differ in ability sort into either a research sector or a manufacturing sector that produces differentiated goods. Each research project generates a new variety of the differentiated...

Over the last three decades there has been a dramatic increase in the size of the financial sector and in the compensation of financial executives. This increase has been associated with greater risk-taking and the use of more complex financial instruments. Parallel to this trend, the...

This paper explores the distributional impact of commodity price shocks over the both the short and very long run. Using a GARCH model, we find that Australia experienced more volatility than many commodity exporting poor countries between 1865 and 2007. A single equation error correction model...

In this paper we argue that very high marginal labor income tax rates are an effective tool for social insurance even when households have preferences with high labor supply elasticity, make dynamic savings decisions, and policies have general equilibrium effects. To make this point we construct...

Which structural reforms affect the speed the regional convergence within a country? We found that domestic financial development, trade/current account openness, better institutional infrastructure, and selected labor market reforms facilitate regional convergence. However, these reforms have...

A fundamental question in social sciences relates to the effect of wealth inequality on economic growth. Yet, in tackling the question, researchers have had to use income as a proxy for wealth. We derive a global measure of wealth inequality from Forbes magazine’s listing of billionaires and...

We develop a monopolistic competition model with two sectors and heterogeneous agents who self-select into entrepreneurship, depending on entrepreneurial ability. The effect of market size on the equilibrium share of entrepreneurs crucially hinges on properties of the lower-tier utility function...
