Economies have markedly different firm size distributions. At the same time, firms of different size grow differently after identical financial- and product-market liberalization reforms. Thus, identical reforms can produce different growth outcomes across countries. This result is reached after...

Grading and providing feedback are two of the most time-consuming activities in education. We developed a randomised controlled trial (RCT) to test whether they could be performed by generative artificial intelligence (Gen-AI). We randomly allocated undergraduate students to feedback provided...

The paper analyzes the influence of credit market liberalization on economic growth in more than 100 economies over a period of 30 years. Liberalizing early and consistently is associated with higher living standards. However, although the timing of the reform seems to matter in raising living...

We set up a tractable general equilibrium (GE) model to study how output of firms of different size grows after entry and labor reforms. We then take the model predictions to the largest global publicly available firm-level data set: the Enterprise Surveys data. The results demonstrate that...

Post-crisis policy making increasingly focuses on doing business reforms. We argue that the effects of those reforms will be different across countries. To understand the reasons for the reform outcome divergence, we advance a novel firm-size distribution (FSDs) argument. At the center of the...

This book offers an extensive review of market-oriented economic reforms since 1970, and considers the question of whether more liberal economic policy yields greater social welfare. The author demonstrates that, despite the widespread uniformity of economic policy across countries over the past...

The paper analyzes the influence of credit-, labor-, and product market deregulation policies on economic growth in more than 70 economies over a period of 30 years. It addresses both the issues of reform measurement and its endogeneity. Specifically, by combining a difference-in-difference...

This research studies the specific determinants of the choice of exchange rate regime in resource-rich countries. We run multinomial logit regressions for an unbalanced panel data set of 145 countries over the 1975-2004 period. We find that resource-rich countries are more likely to adopt a...
