The public health measures implemented by governments to limit the spread of the COVID-19 pandemic will produce significant economic consequences that are likely to exacerbate social and economic inequalities. In this paper we provide a framework to analyse how income inequality, besides other...

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 micro-founded general equilibrium model with heterogeneous agents and three dimensions of financial inclusion: access (determined by a participation cost), depth (determined by a borrowing constraint), and intermediation efficiency (determined by a monitoring cost). We find that the...

Much of the new growth literature stresses country characteristics, such as education levels or political stability, as the dominant determinant of growth. However, growth rates are highly unstable over time, with a correlation across decades of .1 to .3, while country characteristics are...

Analysis based on a new measure of financial distress for 24 advanced economies in the postwar period shows substantial variation in the aftermath of financial crises. This paper examines the role that macroeconomic policy plays in explaining this variation. We find that the degree of monetary...

Regulation of economic activity is ubiquitous around the world, yet standard theories predict it should be rather uncommon. I argue that the ubiquity of regulation is explained not so much by the failure of markets, or by asymmetric information, as by the failure of courts to solve contract and...

A number of market failures have been associated with R&D investments and significant amounts of public money have been spent on programs to stimulate innovative activities. In this paper, we review some recent microeconomic studies evaluating effects of government sponsored commercial R&D. We...

Amid rising global interest in state interventions, this paper examines how China's infrastructure investments--a key macroeconomic policy tool--affect firm productivity. We focus on a policy that encourages regional governments to improve market conditions for private enterprises. Our analysis...

This paper reviews recent research dealing with fiscal discipline and revisit the issues of fiscal control in federal systems, focusing on selective case studies covering the 2000s, before and after the Global Financial Crisis (GFC). We start by contrasting the recent fiscal history of...

In this lecture, I argue that there are remarkable parallels between how monetary and fiscal policies operate on the macro economy and that these parallels are sufficient to lead us to think about transforming fiscal policy and fiscal institutions as many countries have transformed monetary...
