This paper proposes finite-sample procedures for testing the SURE specification in multi-equation regression models, i.e. whether the disturbances in different equations are contemporaneously uncorrelated or not. We apply the technique of Monte Carlo (MC) tests [Dwass (1957), Barnard (1963)] to...

Statistical tests in vector autoregressive (VAR) models are typically based on large-sample approximations, involving the use of asymptotic distributions or bootstrap techniques. After documenting that such methods can be very misleading even with fairly large samples, especially when the number...

We propose methods for testing hypothesis of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

In this paper, we use identification-robust methods to assess the empirical adequacy of a New Keynesian Phillips Curve (NKPC) equation. We focus on the Gali and Gertler's (1999) specification, on both U.S. and Canadian data. Two variants of the model are studied: one based on a...

This paper proposes a new nonparametric test for conditional independence, which is based on the comparison of Bernstein copula densities using the Hellinger distance. The test is easy to implement because it does not involve a weighting function in the test statistic, and it can be applied in...

We study the interactions between the capital structure and the technological flexibility choices of firms in a duopoly. When there are bankruptcy costs, a leveraged firm may modify its strategic choices in order to decrease its probability of bankruptcy. We show that, when the capacity level of...

This paper examines the impact of capital structure on the optimality of contingent financial contracts. The role of financial relationships is not only to provide funds but also to offer insurance to a risk adverse entrepreneur through contingent financial transfers. Since such financial...

This study deals with the evolution of the financing of large Canadian companies from 1960 to 1994. Part I shows that there hass been no significant increase in total corporate debt in Canada, as there has been in the U.S. Total indebtness increased between 1960 and 1982 and then declined; by...

Using a unique panel data of Dutch innovation and financial variables we empirically investigate how financing and innovation vary across firm characteristics. The study also tries to gauge the extent of market failure due to the presence of financing frictions. Our main findings can be...

In this paper, we analyze hyper-return periods from 1976 to 1994 for 20 emerging stock markets. We define a hyper-return period as a calendar year during which a cumulative geometric return in excess of 70% is observed. According to this definition, the hyper-return periods represent 23% of the...
