This study assesses the effects of maternal healthcare on child survival by using nonrandomized data from a cross-sectional survey in Azerbaijan. Using 2SLS and simultaneous equation bivariate probit models, we estimate the effects of delivering in healthcare facility on probability of child survival taking into account self-selection into the treatment. For women who delivered at healthcare fa...

This paper proposes and discusses an instrumental variable estimator that can be of particular relevance when many instruments are available. Intuition and recent work (see, e.g., Hahn (2002)) suggest that parsimonious devices used in the construction of the final instruments, may provide effective estimation strategies. Shrinkage is a well known approach that promotes parsimony. We consider a ...

We examine the relationship between bank’s equity ownership and corporate financial performance based on cross-sectional data through 2SLS estimation model. Our evidence is listed 3203 non...

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...

The study investigated the determinants of birth weight in Botswana using instrumental variable (2SLS) model applied to the Botswana Family Health Survey (BFHS) data for 1996. The findings suggest that birth weight is positively and significantly influenced by the mother’s socioeconomic characteristics (tetanus immunization status, age, education level) and the husband’s education level. From t...

I use the bootstrap to study a comprehensive sample of 1400 instrumental variables regressions in 32 papers published in the journals of the American Economic Association. IV estimates are more often found to be falsely significant and more sensitive to outliers than OLS, while having a higher mean squared error around the IV population moment. There is little evidence that OLS estimates are su...

Stefani Kostagianni, Department of Economics and Finance and Centre for Economic Development and Institutions (CEDI), Brunel University, London, United Kingdom, E-mail: [email protected] ABSTRACT. We investigate the effect of IMF assistance on economic growth in a broad panel of countries. We argue that countries are likely self-select into seeking IMF involvement based on their ...

This paper examines whether lax environmental policy and abundant natural resources both attract foreign direct investment (FDI). At first, their potential effects are discussed using arguments from the pollution haven hypothesis and the natural resource curse. Using cross-country Ordinary Least Square (OLS) regressions and robustness checks like Instrumental Variable Two-Stage Least Squares (I...

This study integrates the constructs of organisational change strategies, market orientation, top management behaviour, leadership style, learning orientation and business performance. A survey was sent to the top 2,000 organisations within Australia, as defined by annual revenue. Data was analysed using twostage least squares regression (2SLS). Findings indicate that both planned and emergent ...
