Cet article propose une synthèse de la littérature concernant les tests de racine unitaire en panel. Deux principales évolutions peuvent être mises en évidence dans cette voie de recherche depuis les travaux fondateurs de Levin et Lin (1992). D'une part, on a pu assister depuis la fin des...

This article proposes an overview of the recent developments relating to panel unit root tests. After a brief review of the first generation panel unit root tests, this paper focuses on the tests belonging to the second generation. The latter category of tests is characterized by the rejection...

[eng] Our article presents an overview of panel unit-root tests. There are two major trends in this research area. First, since the late 1990s, the work on panel unit-root tests aims to take account of heterogeneity in dynamic properties of series. Second, attempts have recently been made to...

[eng] This paper offers an overview of panel-data cointegration tests. We present the main tests based on the null hypothesis of no cointegration (Pedroni, Kao, Bai and Ng test ; Groen and Kleibergen test ) and the McCoskey and Kao test based on the null hypothesis of cointegration. We also...

This paper proposes intraday High Frequency Risk (HFR) measures for market risk in the case of irregularly spaced high-frequency data. In this context, we distinguish three concepts of value-at-risk (VaR): the total VaR, the marginal (or per-time-unit) VaR, and the instantaneous VaR. Since the...

Using a nonlinear panel data model, we examine the threshold effects in the productivity of the public capital stocks for a panel of 21 OECD countries observed over 1965-2001. Using the so-called "augmented production function" approach, we estimate various specifications of a Panel Smooth...

We present an evaluation of the main empirical approaches used in the literature to estimate the contribution of public capital stock to growth and private factors' productivity. Based on a simple stochastic general equilibrium model, built as to reproduce the main long-run relations observed in...

This paper proposes a new approach to date extreme financial cycles. Elaborating on recent methods in extreme value theory, it elaborates an extension of the famous calculus rule to detect extreme peaks and troughs. Applied on United-States stock market since 1871, it leads to a dating of these...

We identify a potential bias in the methodology disclosed in July 2013 by the Basel Committee on Banking Supervision (BCBS) for identifying systemically important financial banks. Contrary to the original objective, the relative importance of the five categories of risk importance (size,...

As most Exchange-Traded Funds (ETFs) engage in securities lending or are based on total return swaps, they expose their investors to counterparty risk. To mitigate the funds' exposure, their counterparties must pledge collateral. In this paper, we present a framework to study collateral risk and...
