This paper conducts tests of the random walk hypothesis and market efficiency for 14 national public real estate markets. Random walk properties of equity prices influence the return dynamics and determine the trading strategies of investors. To examine the stochastic properties of local real...

We examine the world's largest carbon exchange, ICE's ECX, by applying Chordia et al.'s (2008) conception of short-horizon return predictability as an inverse indicator of market efficiency. We find a strong relationship between liquidity and market efficiency such that when spreads narrow,...

This paper is amongst the first to investigate weak-form efficiency of the most developed (G-20) countries in the world. It also measures the impact of the 2007 financial crisis on the stock markets of these countries, in terms of their efficiency. Serial correlation test, ADF unit root test, Lo...

In the U.S., momentum portfolios formed on returns from 12 to seven months prior to the current month deliver higher returns than momentum portfolios formed from six to two months prior, suggesting an “echo” in returns (Novy-Marx (2012)). In 37 countries not including the U.S., there is no...

We investigate the role of trade credit links in generating cross-border return predictability between international firms. Using data from 43 countries from 1993 to 2009, we find that firms with high trade credit located in producer countries have stock returns that are strongly predictable...

We estimate global return autocorrelation by using the quantile autocorrelation model and investigate its determinants across 43 stock markets from 1980 to 2013. Although our results document a decline in autocorrelation across the entire sample period for all countries, return autocorrelation...

This paper analyzes whether country-specific or foreign Economic Policy Uncertainty (EPU) can explain time-series variation in momentum returns in some international stock markets. First, we empirically tested three EPU index series on the return of Long-Short portfolios of momentum-based...

We exploit the merger between BlackRock and Barclays Global Investors to study how changes in expected ownership concentration affect the investment behavior of funds and the cross-section of stocks worldwide. We find that funds with open-end structures and a large exposure to commonly-held...

We provide a historical perspective focusing on Ziemba's experiences and research on the bond-stock earnings yield differential model (BSEYD) starting from when he first used it in Japan in 1988 through to the present in 2014. The model has called many but not all crashes. Those called have high...

We provide evidence for a causal link between the US economy and the global financial cycle. Using a unique intraday dataset, we show that US macroeconomic news releases have large and significant effects on global risky asset prices. Stock price indexes of 27 countries, commodity prices, and...
