Computing Optimal Policy in a Timeless-Perspective: An Application to a Small-Open Economy

Staff Working Paper 2007-32 Michel Juillard, Florian Pelgrin
Since the contribution of Kydland and Prescott (1977), it is well known that the optimal Ramsey policy is time inconsistent. In a series of recent contributions, Woodford (2003) proposes a new methodology to circumvent this problem, namely the timeless perspective solution.

Time-Consistent Control in Non-Linear Models

Staff Working Paper 2007-3 Steve Ambler, Florian Pelgrin
We show how to use optimal control theory to derive optimal time-consistent Markov-perfect government policies in nonlinear dynamic general equilibrium models, extending the result of Cohen and Michel (1988) for models with quadratic objective functions and linear dynamics. We replace private agents' costates by flexible functions of current states in the government's maximization problem.

The Implications of Transmission and Information Lags for the Stabilization Bias and Optimal Delegation

Staff Working Paper 2004-37 Jean-Paul Lam, Florian Pelgrin
In two recent papers, Jensen (2002) and Walsh (2003), using a hybrid New Keynesian model, demonstrate that a regime that targets either nominal income growth or the change in the output gap can effectively replicate the outcome under commitment and hence reduce the size of the stabilization bias.

The U.S. New Keynesian Phillips Curve: An Empirical Assessment

Staff Working Paper 2004-35 Alain Guay, Florian Pelgrin
The authors examine the evidence presented by Galí and Gertler (1999) and Galí, Gertler, and Lopez-Salido (2001, 2003) that the inflation dynamics in the United States can be well-described by the New Keynesian Phillips curve (NKPC).

Translog ou Cobb-Douglas? Le rôle des durées d'utilisation des facteurs

Staff Working Paper 2004-19 Eric Heyer, Florian Pelgrin, Arnaud Sylvain
Using French data on industrial firms over the period 1989-2001, the authors estimate a "flexible" Translog production function that accounts for the volumes and durations of factor utilization.

National Saving–Investment Dynamics and International Capital Mobility

Staff Working Paper 2004-14 Florian Pelgrin, Sebastian Schich
The authors analyze the dynamics of national saving–investment relationships to determine the degree of international capital mobility.

Contraintes de liquidité et capital humain dans une petite économie ouverte

Staff Working Paper 2004-13 Florian Pelgrin
In an overlapping-generations model that represents a small open economy, where agents live two periods, liquidity constraints lead to low economic development when the only accumulable factor is human capital.

Durées d'utilisation des facteurs et fonction de production : une estimation par la méthode des moments généralisés en système

Staff Working Paper 2004-12 Eric Heyer, Florian Pelgrin, Arnaud Sylvain
Although a number of studies have demonstrated the importance of the degree of factor utilization in economic analysis, the impact of the durations of utilization in a production function remains largely unknown, particularly in terms of the duration of equipment utilization.
