This paper derives the limiting distributions of alternative jackknife IV (JIV ) estimators and gives formulae for accompanying consistent standard errors in the presence of heteroskedasticity and many instruments. The asymptotic framework includes the many instrument sequence of Bekker (1994) and the many weak instrument sequence of Chao and Swanson (2005). We show that JIV estimators are asym...

This paper shows that neither OLS nor 2SLS can generically identify policy trade offs in the linear case, except under extreme assumptions. Practitioners must be content with near identification and discusses how to choose between these two methods. It a two-stage approach using preference proxies elicit hidden information potentially narrow gap simple specification test used assess whether rea...

The study aims to look into the effect of electricity, energy, and natural resource rent on Foreign Direct Investment (FDI). Panel data from 198 countries was compiled for period 1990 2018. OLS, POLS, DK, 2SLS, GMM models are used in this study. In all models, we discovered that access energy is positively related with FDI. except POLS GMM, intensity level primary green power output had a signi...

In this paper, we revisit the relationship between governance and human development in Africa during period 2010-2019 taking into account existence of spatial dependence controlling endogeneity problem through a Generalized Spatial Two Stage Least Squares (2SLS). The exploratory data analysis reveals quality. Our empirical findings support that Africa, “good fences make good neighbours” or prox...

This research is aim to get a better understanding of the impact migration on welfare migrants in Indonesia. Using Instrumental Variable 2sls (IV) and IV probit, this study finds that has positive effect income. Nevertheless, it was discovered increases likelihood children being unhealthy causes schooling be interrupted when they should high school. migration's potential detrimental influence h...

In this paper we provide further results on the properties of the IV estimator in the presence of weak instruments.We begin by formalizing the notion of weak identi ̄cation within the local-to-zero asymptotic framework of Staiger and Stock (1997), and deriving explicit analytical formulae for the asymptotic bias and mean square error (MSE) of the IV estimator. These results generalize earlier ̄n...

The paper analyses the impact of geographic innovation on Total Factor Productivity (TFP) in Taiwan in 2001 using 242 four-digit standard industrial classification (SIC) industries. We compute TFP by estimating Translog production functions with K, L, E and M inputs, and measure the geographic innovative activity using both Krugman's Gini coefficients and the location Herfindahl index. We also ...
