Mardi | 2011-10-19 C003 Manuel RUIZ-MARIN We propose the first statistical test to determine, given a spatial process, if the spatial structure is generated by a deterministic, rather than by a stochastic, process. The conditions under which the test can be applied are really weak. The advantages of the presented methods are simplicity, invariance respect to monotonic transformations and the applicability of the test regardless the discrete or continuous nature of the data generating process. We conduct several simulation studies […]

Mercredi | 2011-10-12 William TELKES Nowadays, many biotechnology companies are the source of scientific and technological breakthroughs and this is especially true in the pharmaceutical industry. However, developing such innovations is particularly risky. As these innovative ventures evolve in a context of high uncertainty and as their financial needs are quite large, especially when it comes to fund clinical tests, many of them have great difficulties in finding potential funding sources. Many traditional funding sources, such as banks, are unwilling […]

Mardi | 2011-09-27 B103 Jorge E. RESTREPO – Scott ROGER – Carlos J. GARCIA A DSGE model is used to examine whether including the exchange rate in the central bank’s policy rule can improve economic performance. Smoothing the exchange rate helps both financially robust economies and financially-vulnerable emerging economies in handling risk premium shocks and, given a small weight placed on the exchange rate, the effects on inflation and output volatility are minimal with demand and cost-push shocks. Financially vulnerable […]

Mardi | 2011-06-07 B103 – 16h20 Hippolyte D’ALBIS In this article, we challenge the common thought that the annuity contract proposed by Yaari in his seminal 1965’s paper is optimal. We indeed show, in a standard neo-classical framework, that another contract, which actually resembles much more to the contracts that are proposed in the  » real world » , may be preferred by rational individuals. According to this contract, the annuities are an illiquid asset and the premium is age independent. […]

Mardi | 2011-05-24 B211 Kristian BEHRENS – Giordano MION – Yasusada MURATA – Jens SÜDEKUM The spatial structure of an economy is determined by the trade-off between agglomerationand dispersion forces. This trade-off crucially depends on spatial frictions – trade frictions for shipping goods across cities and urban frictions for concentrating people and firms in cities. Little is known to date about the quantitative importance of those frictions. To fill this gap, we develop a model that allows for the joint […]

Mardi | 2011-05-17 B103 Valentin PATILEA – Hamdi RAÏSSI – libre Linear Vector AutoRegressive (VAR) models where the innovations could beunconditionally heteroscedastic and serially dependent are considered. Thevolatility structure is deterministic and quite general, including breaks ortrending variances as special cases. In this framework we propose OrdinaryLeast Squares (OLS), Generalized Least Squares (GLS) and Adaptive LeastSquares (ALS) procedures. The GLS estimator requires the knowledge ofthe time-varying variance structure while in the ALS approach the unknownvariance is estimated by kernel smoothing […]

Mardi | 2011-05-03 B103 Zied FTITI This paper proposes a new methodology to check the economic performance of a monetary policy and in particular the inflation targeting policy (ITP). The main idea of this work is to consider the ITP as economically efficient when it generates a stable monetary environment. The latter is considered as stable when a long-run equilibrium exists to which the paths of economic variables (inflation rate, interest rate and GDP growth) converge. The convergence of the […]
