We examine estimation of a model of producer behavior in the presence of correlated measurement errors in the regressors. Scale economies and price-cost margins are estimated from a set of panel data for manufacturing plants. The paper presents a somewhat new model for estimation of these...

A model with proportional errors in variables arising naturally in microeconomics is considered. Unlike the classical additive errors case, all OLS parameter estimates exhibit attenuation bias that does not depend on the limiting distribution of the data. The distribution of OLS estimators is...

Measurement of productivity in the service sector has always represented a challenge for economists. "Productivity in the U.S. Services Sector: New Sources of Economic Growth", by Jack Triplett and Barry Bosworth from the Brookings Institution is reviewed. The authors have produced a textbook on...

Estimation in nonlinear time series models has mainly been performed by least squares or maximum likelihood (ML) methods. The paper suggests and studies the performance of generalized method of moments (GMM) and indirect estimators for the autoregressive asymmetric moving average model. Both...

Forecasting using factor models based on large data sets have received ample attention due to the models’ ability to increase forecast accuracy with respect to a range of key macroeconomic variables in the US and the UK. However, forecasts based on such factor models do not uniformly...

This paper introduces an easy to follow method for continuous time model estimation. It serves as an introduction on how to convert a state space model from continuous time to discrete time, how to decompose a hybrid stochastic model into a trend model plus a noise model, how to estimate the...

We examine estimation of a model of producer behavior in the presence of correlated measurement errors in the regressors. Scale economies and price-cost margins are estimated from a set of panel data for manufacturing plants. The paper presents a somewhat new model for estimation of these...

The paper discusses the latest economic crisis and the public policies used to mitigate the recession and improve the economic growth. The current target rate (monetary policy) is closed to zero since December 2008 with a new experimental policy (“quantitative easing”) to stimulate...

The purpose of this paper is to study the model belongs to the family of structural equation models with data varying both across individuals (sectors) and in time. A complete theoretical analysis is developed in this work for the case of a dynamic recursive structure. Maximum likelihood...

The distribution of lifetime is one of the most important factors for the determination of the population volume. Knowing the population volume is of great importance for the future planning. For the future planning depending on the population volume, it is necessary to know the distribution of...
