In this paper we study international linkages when forecasting unemployment rates in a sample of 24 OECD economies. We propose a Global Unemployment Factor (GUF) and test its predictive ability considering in-sample and out-of-sample exercises. Our main results indicate that the predictive...

This paper develops a wavelet (spectral) approach to test the presence of a unit root in a stochastic process. The wavelet approach is appealing, since it is based directly on the different behavior of the spectra of a unit root process and that of a short memory stationary process. By...

This paper presents a software package that implements Bayesian Model Averaging for Autoregressive Distributed Lag models BMA_ADL ver.~0.9 in gretl. Gretl (the GNU regression, econometrics and time-series library) is an increasingly popular free, open-source software for econometric analysis...

Life annuities reserving as well as populations projections require projecting the age-specific mortality rates into the future. In Algeria, mortality forecasts are still based on the United Nations methodology, which remains highly recommended when national data are not available or enough...

Advances in gravity literature have presented econometric approaches for the theoretically consistent estimation of structural gravity. When estimating the impact of policy-shocks on trade values however, researchers are confronted with two problems. Once multilateral resistances are taken into...

It is well known that Local Projections (LP) residuals are autocorrelated. Conventional wisdom says that LP have to be estimated by OLS with Newey and West (1987) (or some type of Heteroskedastic and Autocorrelation Consistent (HAC)) standard errors and that GLS is not possible because the...

Internal and external institutions play a crucial role in the firms’ decision-making process and their productivity. Along with internal institutional features, such as the corporate ownership structure, external institutions, such as the stringency of market and environmental regulations,...

In this paper, method of Lagrange multipliers is used to investigate the utility function; subject to two constraints: budget constraint, and coupon constraint, and to verify that the utility is maximized. An economic model of an emerging firm has been developed here by considering four...

Semiparametric models are useful in econometrics, social sciences and medicine application. In this paper, a new estimator based on least square methods is proposed to estimate the direction of unknown parameters in semi-parametric models. The proposed estimator is consistent and has asymptotic...
