This paper builds a model of high-frequency equity returns by separately modeling the dynamics of trade-time returns and trade arrivals. Our main contributions are threefold. First, we characterize the distributional behavior of high-frequency asset returns both in ordinary clock time and in...

Focusing on the foreign exchange reaction to macroeconomic announcements, we show that fast trading is positively and significantly correlated with the entropy of the distribution of quoted prices in reaction to news: a larger share of fast trading increases the degree of diversity of quotes in...

This study examines the contradictory predictions regarding the association between the premium paid in acquisitions and deal size. We document a robust negative relation between offer premia and target size, indicating that acquirers tend to pay less for large firms, not more. We also find that...

This paper examines changes in acquirer and target companies' Credit Default Swap (CDS) spreads as a proxy for default risk around official mergers and acquisitions (M&A) announce-ments. Related literature extensively documents wealth effects triggered by M&A from the shareholders' perspective,...

This paper examines changes in Credit Default Swap (CDS) spreads as a proxy for default risk after M&A announcement for the companies involved. Existing literature extensively documents wealth effects triggered by M&A announcements from the shareholders' perspective, but there is limited...
