This chapter reviews developments to improve on the poor performance of the standard GMM estimator for highly autoregressive panel series. It considers the use of the ‘system’ GMM estimator that relies on relatively mild restrictions on the initial condition process. This system GMM estimator encompasses the GMM estimator based on the non-linear moment conditions available in the dynamic error components model and has substantial asymptotic efficiency gains. Simulations, that include weakly exogenous covariates, find large finite sample biases and very low precision for the standard first differenced estimator. The use of the system GMM estimator not only greatly improves the precision but also greatly reduces the finite sample bias. An application to panel production function data for the U.S. is provided and confirms these theoretical and experimental findings.

In this study, we empirically investigate the effect of military expenditure on economic growth in the five South Asian countries of Bangladesh, India, Pakistan, Nepal, and Sri Lanka over the period of 1990–2006. By applying a Solow Growth Model, empirical evidences derived from panel estimation methods indicate that defense has a negative effect on economic growth in the region.

This chapter examines the influence of outsourcing on airlines’ performance from countries of the Asia Pacific region. Performance in the context of this study is drawn from productivity growth and technical efficiency scores that are calculated using the standard data envelopment analysis (DEA) approach. We utilize data from airlines over the period 2003–2011 and estimate the impact of outsourcing on productivity and technical efficiency using generalized method of moments (GMM) estimators. The findings from DEA reveal an improvement in the technical efficiency score of airlines from Asia Pacific. Nonetheless, productivity estimates indicate fluctuations in the productivity growth trend of airlines, attributable to global economic recession in 2007/2008. GMM estimation results, however, suggest negative impacts of outsourcing on technical efficiency and productivity of the airlines from Asia Pacific countries. We offer several explanations for these outsourcing findings. Heavy outsourcing of airlines activities particularly maintenance of aircraft may negatively affect aircraft utilization and ultimately erode the service level of airlines. The erosion of the service level of airlines would affect the demand for air travel in a downward manner, thereby lowering the technical efficiency and productivity of airlines. Also, relatively low labor costs enjoyed by airlines in the Asia Pacific region would suggest that having many airline activities in-house would save operating expenses attributable to labor costs.

Although various studies have investigated the corporate political activity (CPA), however, there is no definite report which shows its effect on the public policy outcome or the organization’s performance. Hence, the political effects of the corporate social responsibility (CSR) have garnered a lot of recent interest since the CSR included activities which have an intended or an unintended effect on the CPA–corporate financial performance (CFP) link. We use data made available by the 1995 Lobbying Disclosure Act, while the CSR indices were gathered from the Fortune Magazine’s most admired companies from 2007 to 2016. We analyzed the relationship between the organization’s CPA and CFP, with the help of the dynamic panel data system generalized method of moment (GMM) estimation. Their results showed that the CPA did not improve the firm’s performance. Moreover, CPA and CSR are substitute in affecting financial performance, because they are essentially exclusive investments that require resources but do not have synergies.

This current research tries to answer the widespread debate about the role of derivatives in propagating the last financial crisis. So, this work aims to examine the effect of derivatives on bank stability in emerging countries by using the bank stability index (BSI) as developed by Ghosh (2011) from three major dimensions of banking operations: stability, soundness, and profitability. We use the generalized method of moments (GMM) estimator technique developed by Blundell and Bond (1998) to estimate regressions during the normal, the turbulent, and the whole period, following the guidance given by Chiaramonte, Poli, and Oriani (2013).

The major conclusion of this study reveals that except to futures the other derivative instruments cannot be considered as troubling factors. The main implication of the research shows that derivatives – in general – are not responsible for the propagation of the recent financial crisis. Hence, the common debate accusing derivatives as being responsible for the aggravation of the recent financial crisis should be rejected.

The main objective of this study is to identify the main determinants of the Islamic banks’ performance in Gulf Cooperation Council (GCC) regions.

The research uses both static model (fixed effects and random effects) and Generalized method of Moments (GMM). The data for this study are obtained from the annual reports of 29 Islamic banks from GCC countries using Bankscope database for the period from 2005 to 2013.

The empirical findings reveal that Islamic banks’ specific factors such as the equity financing and bank size are positive and statistically significant to the profitability of Islamic banks. The operating efficiency ratio is negatively and statistically significant to return on asset. It is also found that macroeconomic variables such as money supply and inflation are negatively and statistically significant to the performance of Islamic banks whereas oil price has been found positive and statistically significant to the performance of Islamic banks in the GCC region.

The present study seeks to fill a demanding gap in the literature by providing new empirical evidence on the factors that influence the profitability of the Islamic banking sector in GCC regions.

These findings have significant contribution to the literature by comprehensively clarifying and critically analyzing the current state of profitability among the Islamic banks in GCC regions.

Private standards are increasingly governing international food trade, but little is known about the implications for developing countries. The objective of the study is to provide evidence in the ongoing debate on standards as barrier or catalyst for developing countries’ export. We use the Peruvian fresh asparagus export sector as a case study and provide empirical panel data evidence on the effects of certification to private food standards on export volumes of firms. Our dataset on the transactions of 567 export firms from 1993 to 2011 allows us to take export dynamics and time trends into account, as well as to keep country and sector specific effects constant. In our empirical strategy, we first use simple OLS and ignore firm-specific unobservable effects and dynamic export patterns. We then account for export persistence, as well as company fixed effects and finally, use System-GMM estimators to address potential reversed causality issues. These approaches represent substantial methodological improvements compared with previous studies on the trade effects of private standards. The empirical innovation is crucial for accurate impact estimation, as results indicate that certification to standards has a positive effect on the export volumes of companies, but that the significant effect dwindles as soon as unobserved firm heterogeneity and export persistency are properly controlled for. Additional studies with large data availabilities are needed to further disentangle the effect and confirm the case study results.

The purpose of the study is to investigate the impact of tax planning activities on the firm value of FTSE 100 firms. We employ static and dynamic panel regression analyses on a sample of 70 companies drawn from the UK FTSE 100 over a five-year period (2006–2010). Empirical evidence suggests that tax planning activity as measured by the proxies based on reported accounting information has a negative impact on firm value. Moreover, the results from the Generalized Methods of Moments (GMM) models suggest significant dynamics in firm value, i.e., the current firm value is positively affected by the past firm value. The findings imply the need for a full review of the adequacy and relevance of tax accounting disclosure and therefore have policy implications for accounting standard setters.

The major objective of this study is to inspect the differences in the effect of derivatives on the stability between banks from emerging countries and those from recently developed countries.

According to the repercussions of the recent financial crisis, we divide the whole period into normal period “the pre-crisis period,” 2003–2006, and turbulent period “the crisis & post-crisis period,” 2007–2011. We use the Generalized Methods of Moments (GMM) estimator technique developed by Blundell and Bond (1998) to estimate our regressions.

Our main conclusions show that, in general, using derivatives by banks from emerging countries deteriorates their stability especially during the turbulent period, whereas, using derivatives do not weaken the stability of banks from recently developed countries. We deduce that banks from emerging countries are more destabilized by using derivatives than banks from recently developed countries.
