We discuss the use of event studies in macroeconomics and finance, arguing that many important macro-finance questions can only be answered using event studies with high-frequency financial market data. We provide a broad picture of the use of event studies, along with their limitations. As...

The paper analyzes the integration of euro area sovereign bond markets during the European sovereign debt crisis. It tests for contagion (i.e., an intensification in the transmission of shocks across countries), fragmentation (a reduction in spillovers) and flight-to-quality patterns, exploiting...

We study high-frequency exchange rate movements over the sample 1993-2007. We document that the (Swiss) franc, euro, Japanese yen and the pound tend to appreciate against the U.S. dollar when (a) S&P has negative returns; (b) U.S. bond prices increase; and (c) when currency markets become more...

This Paper proposes a structural time series model for the intra-day price dynamics of fragmented financial markets. We generalize the structural model of Hasbrouck (1993) to a multivariate setting. We discuss identification issues and propose a new measure for the contribution of each market to...

This Paper provides the first empirical examination of the microstructure of the euro money market, using tick data from brokers located in six countries. Special emphasis is put on the institutional environment (monetary policy decisions and their implementation, payment systems and private...

The size of the economic shocks triggered by the COVID-19 pandemic and the effects of the associated non-pharmaceutical interventions have not been fully assessed, because the official economic indicators have not been published. This paper provides estimates of the economic impacts of the...

How much an economy should invest in its physical infrastructure is a crucial question being asked by policy makers from developing countries where financial resources for economic development are limited. This paper aims to address this question by bringing insights from the literature that...

We present a careful analysis of possible issues of the application of the self-excited Hawkes process to high-frequency financial data and carefully analyze a set of effects that lead to significant biases in the estimation of the "criticality index'' n that quantifies the degree of endogeneity...

We investigate the distributions of e-drawdowns and e-drawups of the most liquid futures financial contracts of the world at time scales of 30 seconds. The e-drawdowns (resp. e-drawups) generalise the notion of runs of negative (resp. positive) returns so as to capture the risks to which...
