Using newly-constructed data covering the last decade, we document that, in most of forty markets, when added to the main index, firms’ returns experience an increase in comovement with the rest of the index, reflected in higher beta and greater explanatory power of the market return....

Financial frictions have been identified as key factors affecting economic fluctuations and growth. But, can institutional reforms reduce financial frictions? Based on a canonical investment model, we consider two potential channels: (i) financial transaction costs at the firm level; and (ii)...

Using an enhanced version of the standard investment model, we estimate how institutions affect financial frictions at the firm (micro) level and, through the required rate of return, at the country (macro) level. Based on some 78,000 firm–year observations from 40 countries over the period...

Financial frictions have been identified as key factors affecting both short-term economic fluctuations and long-term growth. An important policy question therefore is whether institutional reforms can reduce financial frictions and, if so, which reforms are best? We address this question by...

We document increased stock price comovement for companies added to major indices around the world. Using data on forty developed and emerging markets for 10 years, we find that in most markets, when added to a major index, firms experience an increase in their beta (especially if their...

We study how financial systems and institutional environments affect investment efficiency using a sample of some 300,000 firm-years from 48 countries. Based on a canonical investment model, we identify two possible channels by which institutional environments may affect investment: firm-level...

We investigate company additions to stock market indices over a six-year period in 39 developed and emerging markets around the world. For most markets, we find a post-inclusion increase in beta and an increase in the explanatory power of market returns (R2), reflecting increased comovement...
