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...

This paper depicts the frameworks of spatial regression methods which cover interaction effects and apply it to analyze distribution poverty area for five districts in West Sulawesi. These consider queen contiguity-based weights create spatially lagged variables Spatial Lag Model, Error Model (SEM), Durbin Ordinary Least Square (OLS) Model. The percentage represents observed dependent variable ...

Analysis of spatial panel data is of great importance and interest in spatial econometrics. Here we consider cigarette demand in a spatial panel of 46 states of the US over a 30-year period. We construct a demand equation to examine the elasticity of per pack cigarette price and per capita disposable income. The existing spatial panel models account for both spatial autocorrelation and state-wi...

While the gravity model has been one of the most successful applications in empirical trade, various attempts are still made to improve its regression results. One of the recent developments in the econometric technique is to extend the gravity model to a panel data framework and take into consideration the existence of dynamic effects. In this paper, we apply these new techniques to examine th...

This paper presents evidence on the contribution of public capital (infrastructure) to aggregate economic performance using panel data for the U.S. states from 1970 to 2005. Attempts to quantify the role of public or government capital in the production of aggregate output have been beset by thorny econometric issues since the early 1990s. We present estimates of the output elasticity of public...

We propose a semiparametric first-difference estimator for panel censored-selection models where the selection equation is of tobit type. The estimator allows the unit-specific term to be arbitrarily related to regressors. The estimator minimizes a convex function and does not require any smoothing. A simulation study is provided comparing our proposal with the estimators of Wooldridge (Journal...

Using newly developed econometric techniques, Pedroni and Yao (2006) show that China has been experiencing regional income divergence since the Reform Period, and that traditional explanations explaining divergence are insufficient. This paper considers the role of labor mobility in the context of endogenous growth with positive externalities to human capital. Using provincial level data on inc...
