What type of financing for innovative companies? Analysis of investment decisions by venture capitalists – Evidence from a theoretical model of venture capital financing in biotechnology companies

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 […]

How much should inflation targeters care about the exchange rate?

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 […]

Welfare gains from illiquid annuities

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. […]

Spatial frictions (Article non disponible)

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 […]

Adaptive Estimation of Vector Autoregressive Models with Time-Varying Variance: Application to Testing Linear Causality in Mean

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 […]

The Macroeconomic Performance of the Inflation Targeting Policy: An approach based on the Evolutionary Co-Spectral Analysis

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 […]

Identification of Macroeconomic Factors in Large Panels

Mardi | 2011-04-19 B103 Lasse BORK – Hans DEWACHTER – Romain HOUSSA This paper presents a dynamic factor model where the extracted factorsand shocks are given a clear economic interpretation. The economic inter-pretation of the factors is obtained by means of a set of over-identifyingloading restrictions, while the structural shocks are estimated followingstandard practices in the SVAR literature. Estimators based on the EMalgorithm are developed. We apply this framework to a large panel of USmonthly macroeconomic series. In particular, we […]
