this study investigates the relationship between market structure and profitability in the iranian manufacturing industries. in this study, raw data based on international standard industrial classification (at four digit code) has been used. fixed effects panel estimation method (based on diagnostic test results) has been chosen for empirical investigation. the result of the study confirms the...

1.3 Stimulus generation process. Upper panel shows the face decomposed into five independent scales. Middle panel: bubbles sample the information space at random locations, allowing overlapping. Bottom panel shows how bubbles are applied to the appropriate scales to produce a sub-sample of the face List of Figures 6 3.2 Cumulative distribution function (c.d.f.) of Beta-distribution is used as a...

Approaches to the use of the International Labour Office U/C Classification of radiological appearances are considered in the context of multiple readers recording different degrees of abnormality. The Panel on Survey Radiology has been set up to provide a basis for standardization. An example of how the panel may be used in this role is given. The approach will depend on the standards maintain...

This article provides a selective review on the recent developments of some nonlinear nonparametric and semiparametric panel data models. In particular, we focus on two types of modelling frameworks: nonparametric and semiparametric panel data models with deterministic trends, and semiparametric single-index panel data models with individual effects. We also review various estimation methodolog...

Bus system performance varies from city to city, and experience clearly indicates that simply increasing the size of bus fleet cannot always improve bus system performance. It is therefore necessary to identify the major variables of bus system performance in different cities and implement a diversity improvement strategy based on actual problems that cities are facing. Two new indicators, annu...

Studies revealing the positive relationship between trade and income are often criticized with the argument that “development should mean more than rising incomes”. Taking this argument as a base and utilizing panel data, Davies and Quinlivan [1] have demonstrated that increases in trade are positively associated with future increases in social welfare as measured by the Human Development Index...

We propose a framework to estimate earnings distributions and worker and firm unobserved heterogeneity on matched panel data. We introduce two models: a static model that allows for interaction effects between workers and firms, and a dynamic model that allows in addition for Markovian dynamics in earnings and mobility decisions. We establish identification in short panels. We develop a tractab...
