This paper derives a 3SLS estimator for a simultaneous system of spatial autoregressive equations with random effects which can therefore handle endoegeneity, spatial lag dependence, heterogeneity as well as cross equation correlation. This is done by utilizing the Kelejian and Prucha (1998) and Lee (2003) type instruments from the cross-section spatial autoregressive literature and marrying th...

We use U.S. county data (3,058 observations) and 41 conditioning variables to study growth and convergence. Using ordinary least squares (OLS) and three-stage least squares with instrumental variables (3SLS-IV), we report on the full sample and metro, nonmetro, and and regional samples: (1) OLS yields convergence rates around 2%; 3SLS yields 6%–8%; (2) convergence rates vary (for example, the S...

This introduction to the R package systemfit is a slightly modified version of Henningsen and Hamann (2007), published in the Journal of Statistical Software. Many statistical analyses (e.g., in econometrics, biostatistics and experimental design) are based on models containing systems of structurally related equations. The systemfit package provides the capability to estimate systems of linear...

This study investigates the impact of board gender diversity (BGD) on firm performance (FP) for family-owned Indian firms. To do so, this selects a sample 75 top-listed firms period 5 years. For empirical analysis, used appropriate panel data models. robustness, three-stage least square (3SLS) model was used. The findings obtained from models reveal significant positive BGD in terms its differe...

A system of nonlinear biomass component equations was developed for slash pine (Pinus elliottii Engelm. var. elliottii) trees using an econometric approach in which endogenous right-hand-side variables were included some equations. The fitted to data from 306 sampled the southeastern United States with weighted two-stage (2SLS) and three-stage (3SLS) least squares full information maximum-likel...

This paper re-examines the Hotelling model of optimal nonrenewable resource extraction in light of stock effects and technological progress. We assume functional forms for cost and demand so that the solution to the Hotelling problem is a steady-state consistent with the empirical observation that the growth rates of market prices have remained zero over a long period of time. We use data on 14...

این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسله­‌مراتبی جهت پیگیری فرایند توسعه تأمین‌کنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه‌ می‌کند. ابتدا، زمینه‌های تأمین نیازمند سپس واجد شرایط هریک زمینه‌ها به کمک تصمیم‌گیری چندشاخصه بهترین-بدترین مشخص می‌گردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهره‌گیری نظرات خبرگان حوزه‌ی خرید استخراج‌شده‌اند. درنهایت، مدل ریاضی ...

Purpose This study aims at investigating the impact of disclosure and Shariah governance on financial performance in MENASA (Middle East, North Africa Southeast Asia) Islamic banks. Design/methodology/approach We use Generalized Least Squares (GLS) regression models to check interdependence relationship between disclosure, 47 banks (IBs) from ten countries operating region. The sample period is...
