The present study investigated estimate biases in cross-classified random effect modeling (CCREM) and hierarchical linear modeling (HLM) when ignoring a crossed factor in CCREM considering the impact of the feeder and the magnitude of coefficients. There were six simulation factors: the magnitude of coefficient, the correlation between the level 2 residuals, the number of groups, the average number of individuals sampled from each group, the intra-unit correlation coefficient, and the number of feeders. The targeted interests of the coefficients were four fixed effects and two random effects. The results showed that ignoring a crossed factor in cross-classified data causes a parameter bias for the random effects of level 2 predictors and a standard error bias for the fixed effects of intercepts, level 1 predictors, and level 2 predictors. Bayesian information criteria generally outperformed Akaike information criteria in detecting the correct model.

This article selects the listed companies in China’s A-share heavy pollution industry from 2014 to 2018 as samples, uses a random effect model to empirically test the relationship between media attention and corporate environmental performance and examines the impacts of local government environmental protection and property nature on that relationship. Results are as follow: (1) Media attention can significantly affect a company’s environmental performance. The higher the media attention, the greater the company’s supervision and the better its environmental performance. (2) In areas where the government pays less attention to environmental protection, the impact of media on corporate environmental performance is more obvious, but in other areas, the impact of media on environmental performance cannot be reflected; (3) The media attention is very significant for the environmental performance improvement of state-owned enterprises, and it is not obvious in non-state-owned enterprises. (4) A further breakdown of the study found that the role of media attention in corporate environmental performance is only significant in the sample of local governments that have low environmental protection and are state-owned enterprises. This research incorporates the local government’s emphasis on environmental protection into the research field of vision, expands the research scope of media and corporate environmental performance, and also provides new clues and evidence for promoting the active fulfillment of environmental protection responsibilities by companies and local governments.

The Impact

Purpose The purpose of this study is to explore how governance mechanisms (internal and external) enhance the performance of the return on asset (ROA), return on equity (ROE), earning per share (EPS) and dividend payout ratios (DP) of the banks of Pakistan. The study incorporates not only the internal factors of governance (board size, out-ratio, annual general meeting, managerial ownership, institutional ownership, block holder stock ownership and financial transparency) but also the external factors (legal infrastructure and protection of minority shareholders, and the market for corporate control). Design/methodology/approach The sample size of the study consists of 30 banks (public, private and specialized) listed at the Pakistan Stock Exchange (PSE) for the period 2008-2014. The panel data techniques (fixed or random effect model) have been used for the empirical analysis after verification by Hausman (1978) test. Findings The results revealed that not only do the internal mechanisms of governance enhance the performance of the banking sector of Pakistan but external governance also plays a substantial role in enriching the performance. The findings conclude that for a good governance structure, both internal and external mechanisms are equally important, to accelerate the performance of the banking sector. Research limitations/implications Internal and external mechanisms of corporate governance can also be checked by adding some more variables (ownership i.e. foreign, female and family as internal and auditor as external), but they are not added in this work due to data unavailability. Practical implications The study contributes to the literature and could be useful for the policy makers who need to force banks to mandate codes of governance through which they can create an efficient board structure and augment the performance. The investments from different forms of ownership can be accelerated if they follow the codes properly. Social implications The study facilitates the bankers in incorporating sound codes of corporate governance to enhance the performance of the banks. Originality/value This work is unique as no one has explored the impact of external mechanism of governance on the performance of the banking sector of Pakistan.

The Impact

The serious decline in the price of crude oil in recent years has led the state government to look for new sources of revenue and becomes strict and aggressive to the assessment and collection of revenue from the existing sources. This study examines the impact of Corporate Governance Attributes on Tax planning of listed manufacturing companies in Nigeria and Malaysia. The corporate governance parameters include board size and CEO tenure while tax planning is proxied by the effective tax rate and firm size as control variable. The objective is to determine if there is a relationship between corporate governance attributes and tax planning which in turn may improve firm performance. The study adopts comparative and ex-post facto research design and will utilise panel data from annual reports and accounts of the listed companies for the period of five years (2014-2018). The Data were analysed using a panel regression technique to assess the effect of the independent variables on the dependent variable. Hausman specification test was conducted to choose between fixed and random effect estimation and the p-value is0.9863 which insignificant. The resultsfrom random effect estimation modelindicates a negative and significant relationship between CEOT, FSIZE and ETR and a positive relationship between BSIZE and ETR.Therefore, the study concludes that corporate governance mechanism plays a significant role in tax planning and Nigerian manufacturing companies pays high tax charges as compare to Malaysian food and beverages companies.

<p>Components of forming tool dies such as draw ring, ejector pin use AISI 4140 as material for their manufacturing. The integrity of the die cutting tools is essential to achieve adequate product quality. In present study, the influence of plasma nitriding (PN) on the wear behav-iour of AISI 4140 steel was investigated. Full factorial experimental design technique was used to study the main effects and the interaction effects between operational parameters and the response variable. The control factors at their two levels (-1 and +1) were: applied load (4.905N and 14.715N), sliding speed (3.14 m/s and 5.23 m/s), and sliding distance (500m and 1000m).The parameters were coded as A, B, and C, consecutively, and were investigated at two levels (-1 and +1). Response selected was Wear Volume Loss (WVL). The effects of in-dividual variables and their interaction effects for dependent variables, namely, WVL were determined. The process of selecting significant factors, based on statistical tools, is illustrat-ed. Analysis of Variance (ANOVA) was performed to know the impact of individual factors on the WVL. Untreated and PN treated AISI 4140 specimens were investigated using field emission Scanning Electron Microscope (SEM) equipped with Energy Dispersive X-ray (EDX) analyzer. Finally diagnostics tools were used to check adequacy of the model in terms of assumptions of ANOVA. ‘Design Expert-7’ and ‘Minitab 17’ softwares were used in the study. Results of statistical analysis indicate that the most effective parameters in the WVL were load and sliding speed. The interaction between load and sliding speed was the most influencing interaction. Results of regression analysis indicate regression coefficient (R2) to be above 90% which suggests good predictability of the model. ‘Predicted-R2’ and ‘Adjusted-R2’, found to be in good agreement with R2, for both the materials under investigation. More-over, results of SEM microscopy suggest PN to be an effective technique to reduce wear.</p>

The Impact

In this paper, using the panel data of the National Bureau of Statistics database from 2010 to 2019, and using the random effect model, we studied the impact of agricultural infrastructure investment on economic growth. The empirical results show that the investment in agricultural infrastructure can significantly improve the national economy, among which the investment in new infrastructure promotes the economic growth to a certain extent. After comparing the eastern, central and western regions, it is found that the investment in agricultural infrastructure in the western region contributes more to the economic growth, and the statistical results are more significant. Based on the analysis of the role of agricultural infrastructure investment in promoting economic growth, this paper will further discuss the relevant suggestions of the “two new and one heavy” policy in the agricultural field, and promote the adjustment of agricultural industrial structure with the improvement of agricultural infrastructure, and promote the formation of a new development pattern of “double circulation”.

The Impact

Bearing in mind the different nature and the impact of various types of foreign direct investments (FDI) on the one hand, and the specific macroeconomic environment in the post-socialist countries on the other hand, in this paper we reexamine the selected macroeconomic factors that affect the two types of FDI inflows (cross-border mergers and acquisitions and greenfield FDI) in four countries of the former Socialist Federal Republic of Yugoslavia. The study employs the balanced panel data framework and covers twelve-year period (2006-2017). Having performed the Hausman test, we use the random effect model and provide evidence that: (1) the key FDI macroeconomic determinants in stable business conditions, examined in numerous research studies, can have a different impact on FDI in times characterized by unstability and financial crisis, (2) some determinants of FDI inflows have different importance and direction in the case of cross-border M&A and greenfield FDI. Our findings are relevant for policymakers who should reconsider the key factors that fuel the FDI inflows towards their developing economies.

ABSTRACT:  This study is conducted to estimate the impact of the increase in regular and specific excise rates structure simplification on cigar's consumption through its price. Using data in 2015 and applying random effect model for unbalanced panel data on Sigaret Kretek Mesin-type and Sigaret Kretek Tangan-type of the cigar, this study compares the impact of price increases due to both specific excise rate structure simplification and regular increase on the excise rate in cigar’s consumption. The results indicate that increase in the specific excise rate structure simplification has a lower impact on raising cigar’s prices than regular excise rate increases. Furthermore, the impact of price increases due to the specific excise rate structure simplification is greater in reducing cigar’s consumption than the price increases due to regular excise rate increases. In addition, it is found that the average price of Sigaret Kretek Mesin-type is lower and has an average consumption that is much higher than Sigaret Kretek Tangan-type. Overall, this result suggests that the specific excise rate structure simplification's policy should be continued in order to reduce cigar's consumption.Keywords: specific excise rate structure simplification, cigar’s consumption, random effects modelABSTRAK:  Penelitian ini dilakukan untuk mengetahui pengaruh kenaikan tarif cukai biasa maupun spesifik terhadap konsumsi rokok melalui harga jual ecerannya. Rokok yang digunakan adalah rokok jenis Sigaret Kretek Mesin (SKM) dan Sigaret Kretek Tangan (SKT). Dengan menggunakan data tahun 2015 dan menerapkan random effect pada unbalanced panel data, penelitian ini membandingkan pengaruh kenaikan harga jual eceran akibat penyederhanaan struktur tarif cukai spesifik dan kenaikan tarif cukai biasa terhadap konsumsi rokok. Hasil penelitian menunjukkan bahwa penyederhanaan struktur tarif cukai spesifik berpengaruh lebih rendah terhadap kenaikan harga jual eceran rokok dibandingkan dengan akibat kenaikan tarif biasa. Lebih lanjut, pengaruh kenaikan harga jual eceran akibat penyederhanaan struktur tarif cukai spesifik lebih besar dalam mengurangi konsumsi rokok dibandingkan kenaikan harga jual eceran akibat kenaikan tarif cukai biasa. Selain itu ditemukan bahwa harga jual eceran rata-rata rokok jenis Sigaret Kretek Mesin (SKM) lebih rendah dan mempunyai rata-rata konsumsi yang jauh lebih tinggi dibandingkan rokok jenis Sigaret Kretek Tangan (SKT). Secara menyeluruh, temuan ini menyarankan agar kebijakan penyederhanaan struktur tarif cukai perlu dilanjutkan karena efektif untuk mengurangi konsumsi rokok. Kata kunci: Penyederhanaan struktur tarif cukai spesifik, konsumsi rokok, random effects model.

The Impact

This study examines the impact of credit management on firm performance amidst bad debts, among Nigerian deposit banks. Five hypotheses were formulated following the dependent variables of Return on Asset and Tobin Q. The independent variables employed for this study include: Loan Loss Provision, Loan to Deposit Ratio, Equity to Asset Ratio, and Loan Write off. This study is based on ex-post facto research design and employed a panel data set collected from fourteen (14) commercial banks over six years ranging from 2014 to 2019 financial year. We analyzed the data set using descriptive statistics, correlation and Ordinary Least Square Regression Technique. The random effect models established that non-performing loan, loan loss provision and equity to asset impact significantly on banks’ performance in both Return on Asset and Tobin-Q models. This suggests that the sampled banks need to establish efficient arrangements to deal with credit risk management. In all, credit risk management indicators considered in this research are important variables in explaining the profitability of Nigerian commercial banks. However, based on the outcome from the empirical analysis, the study carefully recommends that investors and shareholders in these banks should be aware of the possible use of provisions for losses on non-performing loans by managers for smoothening of profits. The shareholders specifically should be ready to meet optimal agency costs to reduce the manager's information asymmetry by hiring competent internal and external auditors.
