factor demand behavior such as energy demand has an important role in the economic analysis. this issue is a major concern in the developing countries (e.g. iran) which are benefited from vast energy resources. in this paper, the third generation of factor demand models is used to analyze the behavior of capital adjustment in the iranian manufacturing industries. the dataset covers the two-digi...

Although initially originated as a totally empirical relationship to explain the volume of trade between two partners, gravity equation has been the focus of several theoretic models that try to explain it. Specialization models are of great importance in providing a solid theoretic ground for gravity equation in bilateral trade. Some research papers try to improve specialization models by addi...

This paper proposes a new panel model of cross-sectional dependence. The model has a number of potential structural interpretations that relate to economic phenomena such as herding in financial markets. On an econometric level, it provides a flexible approach of modelling interactions across panel units and can generate endogenous cross-sectional dependence that can resemble the dependence tha...

Labor and product market regulations affect the unemployment rate of a country without doubt. Econometricians, however, have yet to establish an unequivocal significance of this impact. Model mis-specification, one of the main underlying problems, is overcome by adopting a Bayesian Model Averaging approach. I apply this method to a panel data set that covers 17 OECD countries for the time perio...

A Note on Decompositions in Fixed Effects Models in the Presence of Time-Invariant Characteristics Though theoretically appealing and very popular amongst labour economists, the interpretation of the unexplained part of the Oaxaca (1973) decomposition as discrimination rather than an omitted variable problem in cross-section data has often been criticised. In this note it is shown that this pro...

− A theoretical framework is developed for decomposing partial factor productivity and measuring technical inefficiency when the underlying technology is characterized by factor non-substitution. With Farrell’s (1957) radial index of technical inefficiency being inappropriate in this case, Russell’s (1985; 1987) non-radial indices are adapted to measure technical inefficiency in a Leontief mode...

Forecasting with Spatial Panel Data This paper compares various forecasts using panel data with spatial error correlation. The true data generating process is assumed to be a simple error component regression model with spatial remainder disturbances of the autoregressive or moving average type. The best linear unbiased predictor is compared with other forecasts ignoring spatial correlation, or...

regarding the decentralization of credits management, this study examined the effect of fiscal policies on gross domestic product of the iranian provinces over the period 2001-2009. therefore, we used dynamic panel data and employed gmm-sys method to examine the model. the results show that the government expenditure and tax multiplier coefficients are less than one in short - run but greater t...

This paper applies a model of market power measurement under product differentiation to the case of the gasoline market in California, using data for the period 1983-1989. Our results show that there is a considerable degree of product differentiation among major brands. This allows firms to exercise local market power over their own specific products, but there are also signals of an important...

This paper uses an independent competing risks framework to model job tenure, with previous labour market status and the duration of the preceding unemployment spell as explanatory variables. We find that jobs that follow an unemployment spell have shorter mean duration than other jobs. Less than one half of jobs that follow unemployment last for twelve months. Multivariate results suggest that...
