This paper investigates the portfolio diversification possibilities between BRICS and the US stock market. Using bootstrap full-sample Granger causality and bootstrap rolling-window sub-sample Granger causality tests, we did not find evidence supporting the causal linkage between BRICS and the US stock markets; time-varying causality was observed for particular sub-samples. Our findings imply that BRICS stock markets can provide diversification possibilities for US investors most of the time; however, such opportunities become extremely limited during crisis periods. We also find that stock markets are more likely to be causally linked if they have similar business conditions, excess returns and size premiums.

We examine the causal impact of financial development (FD) on top income shares for a panel of 14 OECD countries—five Anglo‐Saxon countries, eight continental European countries, and Japan—over a 110‐year period. In our main General Method of Moments estimates, we find that a 1‐percentage‐point change in FD increases the top 1% income share by 0.2%. In distribution terms, a 1‐SD incr=ease in FD increases the top 1% income share by around 0.4 of an SD. The effects are robust to various measures of top income shares and FD and alternative estimation techniques, including nonparametric estimation. FD is typically viewed in positive terms in that it makes it easier to access credit and facilitates economic growth. Our results are important because they contribute to understanding of the potential negative effects of FD.

Until recently, factors determining the decisions made by microfinance institutions (MFIs) to extend loans to business start-ups had not been explored. Recent evidence shows that MFI performance with regard to funds issued for small business start-ups depends on MFI-level characteristics such as profit orientation. We argue that these decisions do not only depend on MFI-specific practices or characteristics, but also on the role ethnic diversity plays. Using data on microfinance lending activities for business start-ups, we examine the impact of ethnic diversity on microenterprise start-ups. Results show that ethnic diversity negatively affects the provision of financial capital for business start-up. Furthermore, results also suggest a negative association between ethnic diversity and the share of female borrowers recorded by MFIs. We examine social networks and outreach as potential channels through which ethnic diversity affects business start-ups.
