The role of jumps in volatility spillovers in foreign exchange markets: meteor shower and heat waves revisited
This paper extends the previous literature on geographic (heat waves) and intertemporal (meteor showers) foreign exchange volatility transmission to characterize the role of jumps and cross-rate propagation. We employ heterogeneous autoregressive (HAR) models to capture the quasi-long-memory properties of volatility and the Shapley-Owen R2 measure to quantify the contributions of components. We conclude that meteor showers are more influential than heat waves, that jumps play a modest but significant role in volatility transmission and that significant, bidirectional cross-rate volatility ...
The costs and benefits of dual trading
This paper finds that marketmaking practices of dual traders are pit-specific. In the S&P 500 futures pit, the authors estimate that, because of a lower price impact, customers of dual traders pay eighteen cents less per contract on their trades, compared with customers of pure brokers. According to the authors' estimates, however, customers pay eleven cents more per contract for a purchase and receive nine cents less per contract for a sale, compared with the prices dual traders obtain for their own trades. Thus, the estimated net benefit of dual trading to customers in the S&P 500 futures ...
