This paper examines the relationship between various types of corn research and development (R&D) and corn prices in the United States through a fixed effects panel data model. This research explores R&D investment from both nonprofit and for-profit institutions and the effect these have corn prices. In addition, we look at the effect that corresponding exogenous changes in corn prices have on ...

abstract in this context, this article tries to presents a conceptual model of the factors affecting the government size and empirical test through econometric generalized methods of moments (gmm) by using data from 15 developing countries, review relationship between fiscal decentralization and the government size. the results of dynamic panel data indicate a positive effect of income and expe...

In this paper, we examine the specification tests which have been proposed for fixed effects in binary panel data model, using several different data generating processes to evaluate the performance of the specification test in different situations. By simulations, we find the specification test based on moment conditions is able to outperform the Lagrange multiplier test proposed by Gurmu (199...

splm is an R package for estimating and testing various spatial panel data specifications. We consider the implementation of both maximum likelihood and generalized moments estimators in the context of fixed as well as random effects spatial panel data models. This paper is a general description of splm and all functionalities are illustrated by application to Munnel (1990) data on 48 US States...
