We propose a flexible nonparametric density estimator for panel data. One possible areas of application is estimation of crop yield distributions whose data tend to be short panels from many geographical units. Taking into account the panel structure of the data can likely improve the efficiency...

This paper extends the partially linear varying coefficient model to contain time trend and nonstationary variables as regressors. We use the profile likelihood method to estimate both time trend coefficient in the linear component and the functional coefficients in the nonlinear component and...

We present an Exponential Series Estimator (ESE) for multivariate densities. The ESE has an appealing information-theoretic interpretation and ensures positive density estimates. We show that if the logarithm of a density p(x) defined on a bounded support has r continuously differentiable...

This paper investigates the impacts of climate change on US returns to research investments on agricultural productivity. We examine this using a historical data set in a panel time-series econometric model of state agricultural productivity. The fitted model allows derivation of the rate of...

We examine the bidding behavior of students and non-students in experimental auctions by comparing their willingness to pay (WTP) values for a good. Our results suggest that there is no significant difference between the WTP bids of the two groups.

We use three conventional inequality indices-the Gini, the coefficient of variation of income, and the relative mean deviation of income-and the Atkinson index to examine the effect of income tax rates, the minimum wage, and all the major government welfare and transfer programs on the evolution...
