The econometric theory for panel data regressions was largely developed for survey data where N the number of individuals was large and T the number of time periods small. The asymptotic statistical theory was derived by letting N → ∞ for fixed T . In recent years there has been growing interest in cases, such as sets of countries, regions or industries, where there are fairly long time-series ...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
The most popular econometric models in the panel data literature are the class of linear panel data models with unobserved individualand/or time-specific effects. The consistency of parameter estimators and the validity of their economic interpretations as marginal effects crucially depend on the correct functional form specification of the linear panel data model. Based on an individual-specif...

Introduction: The role of good governance as a key to development effectiveness has been emphasized in recent years. It has been argued that merely allocating public resources for the right goods and services may not lead to desirable outcomes if budget institutions–involving the budget formulation, execution and monitoring–are malfunctioning. In a way that merely allocating budget resources fo...

This paper estimates demand for Internet portals using a clickstream data panel of 2654 users. It shows that familiar econometric methodologies used to study grocery store scanner data can be applied to analyze advertising-supported Internet markets using clickstream data. In particular, it applies the methodology of Guadagni and Little (1983) to better understand households’ Internet portal ch...
