Mardi | 2013-06-25 B103 Sébastien GALANTI – Zahra BEN BRAHAM Financial analysts issue “buy”, “sell” or “hold” recommendation about stocks. Recommendations have value if investors trade upon them, which should affect prices and trading volumes.

With a database of 2359 recommendations about 55 companies on the Tunisian Stock Exchange (BVMT) from 2005 to 2009, we show that prices and volumes react significantly to […]

Prediction in a Spatial Nested Error Components Panel Data Model

Mardi | 2013-06-11 salle des thèses Badi H. BALTAJI – Alain PIROTTE This paper derives the Best Linear Unbiased Predictor (BLUP) for a spatial nested error components panel data model. This predictor is useful for panel data applications that exhibit spatial dependence and a nested (hierarchical) structure. The predictor allows for unbalancedness in the number of observations in the nested groups. One application includes forecasting average housing prices located in a county nested in a state. We derive the BLUP […]

The Econometrics of the Hodrick-Prescott filter (preliminary)

Mardi | 2013-06-04 B103 Neslihan SAKARYA – Robert DE JONG The Hodrick-Prescott (HP) filter is a commonly used tool in macroeconomics, and is used to extract a trend component from a time series. In this paper, we derive a new representation of the transformation of the data that is implied by the HP fi lter. This representation highlights that the HP filter is a weighted average plus a number of adjustments that are important near the begin and end of […]

Risk Management, Nonlinearity and Aggressiveness in Monetary Policy: The Case of the US Fed

Mardi | 2013-05-21 B103 Jean-Yves GNABO – Diego MOCCERO We contribute to the empirical literature on the risk-management approach to monetary policy by estimating regime switching models where the strength of the response of monetary policy to macroeconomic conditions depends on the level of risk associated with the inflation outlook and risk in financial markets. Using quarterly data for the Greenspan period we find that: i) risk in the inflation outlook and volatility in financial markets are a more powerful […]

Political Incentives and Financial Innovation: The Strategic Use of Toxic Loans by Local Governments

Mardi | 2013-05-07 B103 Christophe PERIGNON – Boris VALLEE We examine the toxic loans sold by investment banks to local governments. Using proprietary data, we show that politicians strategically use these products to increase chances of being re-elected. Consistent with greater incentives to hide debt, toxic loans are utilized significantly more frequently within highly indebted local governments. Incumbent politicians from politically contested areas are also more likely to turn to toxic loans. Using a difference in-differences methodology, we show that […]

Premarital Births in Senegal: an Empirical Investigation of its Consequences (Article non disponible)

Mardi | 2013-04-16 B103 Nathalie GUILBERT – Karine MARAZYAN In Senegal, 16% of young mothers have given births out-of-wedlock. In a country, where fecundity is mainly thought inside the marriage institution, this proportion is rather surprising. In this paper, we are interested in testing the existence of a stigmatization on both the mother and the out of wedlock child. To investigate this question, we examine the consequences of premarital births on women’s marital trajectory and on children’s health in Senegal. […]

Where is the System? (Article non disponible)

Mercredi | 2013-04-10 B103 Sylvain BENOIT The aim of this paper is to emphasize the importance of choosing the level of the system (global, european or national) when dealing with systemic risk. Up to now, additional supervision and regulation were established for global systemically important banks, G-SIBs. The paper highlights the need for managing domestic systemically important banks, D-SIBs. This issue is central when focusing on Europe where each country should identify its D-SIBs whereas the Basel Committee on Banking […]
