Most spatial econometrics work focuses on spatial dependence in the regressand or disturbances. However, Lesage and Pace (2009) as well as Pace and LeSage2009 showed that the bias in β from applying OLS to a regressand generated from a spatial autoregressive process was exacerbated by spatial dependence in the regressor. Also, the marginal likelihood function or restricted maximum likelihood (REML) function includes a determinant term involving the regressors. Therefore, high dependence in the regressor may affect the likelihood through this term. In addition, Bowden and Turkington (1984) showed that regressor temporal autocorrelation had a non-monotonic effect on instrumental variable estimators.

We provide empirical evidence that many common economic variables used as regressors (e.g., income, race, and employment) exhibit high levels of spatial dependence. Based on this observation, we conduct a Monte Carlo study of maximum likelihood (ML), REML and two instrumental variable specifications for spatial autoregressive (SAR) and spatial Durbin models (SDM) in the presence of spatially correlated regressors.

Findings indicate that as spatial dependence in the regressor rises, REML outperforms ML and that performance of the instrumental variable methods suffer. The combination of correlated regressors and the SDM specification provides a challenging environment for instrumental variable techniques.

We also examine estimates of marginal effects and show that these behave better than estimates of the underlying model parameters used to construct marginal effects estimates. Suggestions for improving design of Monte Carlo experiments are provided.

The authors generalize the standard linear-in-means model to allow for multiple types with between and within-type interactions. The authors provide a set of identification conditions of peer effects and consider a two-stage least squares estimation approach. Large sample properties of the proposed estimators are derived. Their performance in finite samples is investigated using Monte Carlo simulations.

African countries are generally fragile. This and other related characteristics affect the potential for growth and development. The purpose of this paper is to investigate whether the effect of FDI on economic growth is contingent on a financial system that accounts for financial market fragility. An important point of departure from earlier studies is the adoption of a new measure of financial market fragility.

Given the uniqueness of the data set, the study uses a panel data and estimates an econometric model using an instrumental variable approach. For robustness purposes, a pooled ordinary least square is also estimated.

The study provides evidence that if the financial market is fragile as in the case of Africa, FDI inflows may have a marginally significant positive impact on economic growth. The findings suggest that fragility in the financial market is a key absorptive capacity and cannot be trivialised when exploring FDI–growth nexus in Africa.

The uniqueness of the data set limited the time period of the study. Nonetheless, the findings are still crucial to policy makers in Africa and other developing countries with similar characteristics.

To the best of the authors’ knowledge, this is the first study in Africa to investigate the FDI–growth nexus which accounts for financial market fragility.

This study aims to answer if inter-state migrants in India play a more active role than their intra-state counterparts in labor force participation and entrepreneurship.

A recursive bivariate probit model is used with an instrumental variable (IV) of the total of inter-state migrants in a city over their historical numbers to tackle the endogeneity issue of the migration decision of the migrants.

Inter-state migrants did a better job than their intra-state counterparts in labor force participation and female inter-state migrants did a better job than their counterparts in wage employment and being day laborers.

The data are from IPUMS and there is no updated nationwide data regrading migration and employment for recent years.

A randomized controlled trail can be carried out near the borders of two states where there are both significant amounts of inter-state and intra-state migrants.

The government and international organizations shall focus on cultivating the skills of the female migrants as well as encouraging the entrepreneurship of both types of migrants.

The study focus is on the comparison between intra- and inter-state migrants based on nationwide survey data and the usage of recursive bivariate model and an effective Instrumental Variable.

Poverty and inequality undoubtedly remain substantial challenges to economic and human developments amid growing emphasis on intellectual property rights (IPRs) (with recent advances in information and communication technology (ICTs)) and good governance. In the first empirical study on the incidence of piracy on inequality in Africa, the purpose of this paper is to examine how a plethora of factors (IPRs laws, education and ICTs and government quality) are instrumental in the piracy-inequality nexus.

Two-stage least squares estimation approaches are applied in which piracy is instrumented with IPRs regimes (treaties), education and ICTs and government quality dynamics.

The main finding suggests that, software piracy is good for the poor as it has a positive income-redistributive effect; consistent with economic and cultural considerations from recent literature. ICTs and education (dissemination of knowledge) are instrumental in this positive redistributive effect, while good governance mitigates inequality beyond the piracy channel.

As a policy implication, in the adoption IPRs, sampled countries should take account of the role less stringent IPRs regimes play on income-redistribution through software piracy. Collateral benefits include among others, the cheap dissemination of knowledge through ICTs which African countries badly need in their quest to become “knowledge economies.” A caveat, however, is that, too much piracy may decrease incentives to innovate. Hence, the need to adopt tighter IPRs regimes in tandem with increasing income-equality.

It is the first empirical assessment of the incidence of piracy on inequality in Africa: a continent with stubbornly high poverty and inequality rates.

The purpose of this paper is to explore the role of external audit quality in reducing firm misreporting practices.

Data are gathered from a number of sources including the Osiris database and firms’ annual reports to construct a comprehensive data set containing financial and non-financial information of over 3,100 publicly listed firms in China during the period 2009–2017. A number of rigorous empirical specifications are utilized with the use of probit, logit and conditional logit regressions, as well as panel pooled OLS and fixed-effect estimators. The IV-2SLS, 2-step system GMM and difference-in-differences techniques are also employed to deal with the potential endogeneity bias to ensure the robustness of the empirical results.

The empirical results reveal that larger firms and firms having more tangible assets and greater retained earnings are more likely to employ a better-quality external auditor. Subsequently, higher audit quality leads to a deterioration in corporate misreporting. However, these results are not homogenous across firms. While we document similar findings in the case of non-state-owned firms, state-owned enterprises (SOEs) appear to have less tendency to hire a higher-quality auditor, and higher-quality auditors in turn do not play a significant role in reducing misreporting practices in SOEs.

This paper contributes to a better understanding of the mechanism to mitigate corporate misreporting practices. It is one of the few to empirically investigate auditor selections and the association between external audit quality and corporate misreporting practices in China.

The purpose of this paper is to investigate the impact of access to credit and safety nets on fertilizer adoption in rural Ethiopia.

A panel data set collected in 2005 and 2007 on 278 households and over 5,700 plots from the Southern Highlands of Ethiopia is examined. The authors developed a theoretical model relating input use and credit contract under third-party credit collateral agreement. The estimation is based on instrumental variables regressions to account for the endogeneity of credit access, and safety nets in fertilizer demand equation.

Despite increasing trends in fertilizer and improved varieties adoption since mid-2003, only 22 percent of the plots in the sample is actually received fertilizer. Households with more assets measured by livestock wealth are more likely to adopt fertilizer but less likely to participate in the local credit market as they have better savings that could be used to buy fertilizer/improved seeds without credit contract. This suggests poorer farmers heavily depend on credit than wealthier. Participation in safety nets programs did not contribute for increased use of fertilizer suggesting that the program either competes with agricultural labor or the low wage income was not enough to pay for farm inputs.

The findings show that with a heavier reliance on credit by poorer farmers it appears that much might be gained by targeting policies toward increasing credit access to this group.

Studies that utilize repeated plot- and household-level observations are limited. To the knowledge, this is the first study showing the relationship between credit accesses, public work program and fertilizer adoption over time in rural Ethiopia.

The primary purpose of this study is to investigate the effects of bank competition on SMEs' access to finance in selected Indian states. Using 9,281 firm-level observations from World Bank Enterprises Survey (WBES), this study tests the market power hypothesis versus the information hypothesis to determine whether bank competition promotes access to finance for financially constrained firms.

The authors measure state-level bank competition using two structural indicators: the Herfindahl Hirschman Index (HHI) and three bank concentration ratios (CR3). The authors apply simple probit regression, probit model with sample selection (PSS) and two-stage least squares (2SLS) to examine the effects of bank competition on firms' financing constraints.

The results obtained through PSS and 2SLS indicate that bank competition alleviates firm's financing constraints and positively impacts its need for a bank loan and the decision to apply for bank credit. However, the prevalence of bank competition in promoting access to finance is more pronounced for small and medium-sized firms than for large firms. Higher bank competition also alleviates the credit constraints faced by female entrepreneurs.

Reserve Bank of India (RBI) and other government stakeholders should ensure bank competition without hampering the agenda of bank consolidation to facilitate access to credit for SMEs. Regulators should also identify and monitor the financial institutions that make an insignificant contribution to promoting competitiveness in the financial system.

Previous studies primarily investigate the effect of bank competition on a firm's access to finance from advanced and cross-country perspectives. This study contributes to the literature on bank competition by examining its role in promoting access to finance from an emerging economy standpoint. Measurement of bank competition indicators at the state level is an additional contribution.

This study aims to explore whether globalization and technology are harmful to health using a global panel data set of 52 countries over the period 1990–2019.

The study focused on four continents: Africa, the Americas, Asia/Oceania and Europe. The authors used four advanced econometric methodologies, which include the standard panel fixed effect (FE), Arellano–Bover/Blundell–Bond dynamic panel, Hausman–Taylor specification and two-stage least squares (FE-2SLS)/Lewbel-2SLS approaches.

The empirical evidence highlights the significance of globalization and technology in promoting global health. The findings suggest that globalization has various impacts on global health indicators and that technology is useful in tracking, monitoring and promoting global health. In addition, the empirical evidence indicates that a truly health-centred process of globalization and technological innovation can only be realized by ensuring that the interests of countries and vulnerable populations to health risks are adequately considered in international decision-making regarding global economic integration.

The authors suggest that achieving the aspiration of global health will entail the use of globalization and information technology to extend human activities and provide equal access to global health.

This study aims to examine the institutional investors’ preferences for internal governance mechanisms (internal audit function and audit committee effectiveness) in an emerging country like Malaysia.

A sample of 2,020 yearly firm observations in Bursa Malaysia over the period 2009-2012 is used. The two-stage least squares using instrumental variables (IV-2SLS) analysis is used to examine the relationships. To corroborate the findings of this study, a regression based on a one-year lag of the independent variables is used. Furthermore, ordinary least square regression and Generalized Method of Moments using instrumental variables (IV-GMM) are used.

Positive associations are found between the internal audit function and audit committee effectiveness and the institutional ownership.

These findings imply that institutional investors gravitate to firms that have high investment in internal audit function and effective audit committee. These findings are consistent with the conjecture that institutional investors try to minimize monitoring and exit costs and meet their fiduciary responsibility by investing in better internal audit firms.

This study offers insights to policymakers interested in enhancing internal governance mechanisms to attract institutional investors.

Limited empirical studies have examined the relation between internal governance mechanisms (internal audit function and audit committee effectiveness) and institutional ownership. This study adds to the existing literature on the importance of internal governance mechanisms by documenting an association between internal audit function and audit committee effectiveness and institutional ownership in an emerging country like Malaysia.
