Using recent activity signature function methodology developed in Todorov and Tauchen (2010), we provide empirical evidence that individual stocks from the New York Stock Exchange are adequately represented by a Brownian motion plus medium to large (rare) jumps thus invalidating the pure-jump...

We propose a new variant of RESET that is appropriate for distributed lag models. Monte Carlo evidence on size and power strongly supports the use of the new variant instead of the traditional RESET.

Patton and Sheppard (2011) develop the concept of signed jumps as the difference between positive and negative realized positive semivariances. This quantity is well-suited for gauging the risk-return trade-off at high-frequency as it is well-defined each day and, contrary to the squared jump...

Based on a sample of drivers in Brasilia's streets, this article investigates whether distraction explains traffic accidents. A probit model is estimated to determine the predictive power of several variables on traffic accidents. The main conclusion drawn from this study is that the proxies...

This paper uses the solution of the linear difference model under rational expectation of Blanchard and Kahn (1980) to test the validity of the inflation stickiness and the Rational Expectation Hypotheses for the Brazilian economy during the period from 06/95 to 09/02. Using the Fuhrer-Moore...

This paper improves the test for deficit sustainability developed by Hatzinikolaou and Simos (2013, henceforth HS) by taking into account structural breaks when deriving critical values for the test. Using quarterly data on the US current-account deficit, 1947.1-2012.2, we find that taking into...
