The Empirical Analysis

Purpose – There are only a limited number of empirical analyses on the impacts of MTRs. According to the data from 2006-2011 by the European Regulators Group (ERG), many countries have continuously reduced their MTRs. This paper therefore aims to enrich the empirical analysis of the impacts of MTRs according to EC policy on retail prices. Design/methodology/approach – This paper applies the one-step generalised method of moments (GMM) approach to dynamic panel data. Findings – The results support the hypothesis that lower MTRs will reduce consumer retail prices, which is consistent with the EC framework. It is therefore recommended that regulators in the calling party network pays (CPNP) regime reduce MTRs to at least the same level as the operators' cost to raise overall social welfare, especially consumer welfare. However, the approach by each country can differ depending on its situation. Originality/value – This study supports the idea that it is appropriate for the EC to regulate MTRs by reducing the rates to at least the same level as the efficient operators' cost, and other regulators with a calling party network pays regime from other regions could also follow this strategy.

Objective The purpose of this paper is to analyse the Spanish business sector’s economic exposure to currency risk in Latin America between 2010 and 2016, testing the effectiveness of hedging with derivatives for the reduction of this risk. Methodology Economic exposure is tested with the Jorion model (1990) using both a currency basket and an individualised analysis for the main currencies sustaining business activities between Spain and Latin America: the Mexican peso, Brazilian real, Argentine peso, Chilean peso, and Colombian peso. For the hedging analysis, dynamic panel data models were estimated using a generalised method of moments. Results The results reveal that the number of firms with significant economic exposure is sensitive to the temporal frequency of the observations. The evidence denotes that the firms’ export profile is predominant, both when considering a basket of Latin American currencies and when individually considering the five main pairs of currencies. The only exception is the Argentine peso, where firms’ import profile is slightly higher. The Chilean peso stands out as the currency with the greatest number of firms with significant exposure. Originality This work provides unpublished evidence on economic exposure to currency risk in Latin America in a recent period characterised by two main aspects: an important devaluation of some Latin American currencies with respect to the euro; and an enhancement of Spanish business activities in the region to favour growth during the recent recession of the Spanish economy.

Purpose This paper aims to assess whether official development assistance (ODA) or foreign aid has been effective in reducing extreme poverty; test whether the type and source of aid matter; and examine whether political or economic freedom enhances aid effectiveness in developing countries. Design/methodology/approach The study uses recent dynamic panel estimation techniques (system generalised method of moments), including those methods which deal with endogeneity by controlling for simultaneity and unobserved heterogeneity. Findings The main findings of the study are: firstly, foreign aid does have a statistically significant poverty reduction effect and the results are consistent across all the three extreme poverty proxies. Secondly, the disaggregation of aid by source and type shows that total aid, grant and bilateral aid are more likely to reduce poverty. Thirdly, political freedom might not be an effective channel through which aid impacts extreme poverty, but aid is more effective in an environment where there is respect for freedom of enterprise. Research limitations/implications As with most cross-country aid–growth–poverty dynamic panel data studies, the challenges of establishing robust causality and accounting for the unobserved country-specific heterogeneity remain apparent. However, given the data availability constraints, generalised method of moments is, to the best of the authors’ knowledge, the most robust empirical strategy when T < N. Future research could explore possibilities of individual country analysis, disaggregating countries by income and also examining the direction of causality between foreign aid, poverty and democracy. Practical implications The policy implications are that the development partners should continue to focus on poverty reduction as the main objective for ODA; aid allocation should be focused on channels which have more poverty-reduction effect, such as per capita income and economic freedom; and aid recipient countries should also focus on reducing inequality. Social implications The main social implications from this study is that it is possible to reduce poverty through ODA. Second, to enhance the effectiveness of foreign aid, ODA allocation should be focussed on channels, which have more poverty-reduction effect, and the host countries should have economic freedom. Originality/value This paper makes a further contribution to the aid effectiveness literature, especially the channels through which foreign aid affects poverty.

The Relationship

Purpose The purpose of this study is to investigate the relationship between corporate social responsibility (CSR) and corporate financial performance (CFP), as the findings on the relationship have been inconsistent and have led to calls to further examine this relationship. However, instead of investigating the connection between CSR and CFP, academics have stated that a contingency viewpoint must be used for uncovering the context and conditions which catalyse the relationship between both constructs. Design/methodology/approach This study acquired the CSR data from 100 companies listed in Fortune’s most admired US companies between 2007 and 2016. These data were used to investigate the CSR–CFP link with the help of the dynamic panel data system, which is the generalised method of moments (GMM) estimator. Findings The results indicate that CSR and CFP have a neutral relationship which characterises the effect between CFP and CSR. However, this study found that financial slack positively affected the CSR–CFP relationship, implying that companies will only benefit from CSR activities if they have excess financial resources. Originality/value This study offers a very distinctive perspective regarding the CSR–CFP link according to the financial slack perspective.

The Relationship

PurposeThe main purpose of this study is to evaluate the probability of default and examine the relationship between default risk and financial performance, with dynamic panel moderation of firm size.Design/methodology/approachThis study utilizes a total of 1,500 firm-year observations from 2013 to 2018 using dynamic panel data approach of generalized method of moments to test the relationship between default risk and financial performance with the moderation effect of the firm size.FindingsThis study establishes the findings that default risk significantly impacts the financial performance. The relationship between distance-to-default (DD) and financial performance is positive, which means the relationship of the independent and dependent variable is inverse. Moreover, this study finds that the firm size is a significant positive moderator between DD and financial performance.Practical implicationsThis study provides new and useful insight into the literature on the relationship between default risk and financial performance. The results of this study provide investors and businesses related to nonfinancial firms in the Pakistan Stock Exchange (PSX) with significant default risk's impact on performance. This study finds, on average, the default probability in KSE ALL indexed companies is 6.12%.Originality/valueThe evidence of the default risk and financial performance on samples of nonfinancial firms has been minimal; mainly, it has been limited to the banking sector. Moreover, the existing studies have only catered the direct effect of only. This study fills that gap and evaluates this relationship in nonfinancial firms. This study also helps in the evaluation of Merton model's performance in the nonfinancial firms.

Purpose This paper aims to investigate the determinants of international bilateral tourism demand in countries of Southern Common Market (specifically, Argentina, Brazil and Uruguay) and Chile. Design/methodology/approach In this study, an augmented gravity model is used to investigate the determinants of international bilateral tourism demand in countries of Southern Common Market. The novel aspect of the analysis is that three models of tourism are defined, depending on the spatial distribution of tourist arrivals and departures. An intra-regional model, an extra-regional model and a general model are estimated using a dynamic panel data model. Findings The results indicate that traditional gravity variables are significant in explaining bilateral inbound arrivals, but the characteristics and the behavior of the demand of tourism vary on whether the country belongs to the sub-regional bloc. Research limitations/implications The differences found in this paper might have some impacts on the desired design and direction of the touristic policies of each country. Originality/value This study analyzes the determinants of international tourism demand through different bilateral relationships, differentiating between intra- and extra-block tourisms.

Purpose The purpose of this paper is to verifying the economic resilience of islands and, in particular, the role of the tourism sector in the reaction to the most recent economic crisis. The analysis concerns insular contexts, such as the greater island regions in the Mediterranean basin. Design/methodology/approach Static and dynamic panel data techniques are used for a sample of 13 island economies over a period of 16 years. Findings Results show that the growth factors for regional islands are similar to the ones usually considered for other regions, but the tourism-led growth hypothesis is highly supported. Tourism demand more than supply plays a role together with accessibility. The crisis has reduced the importance of tourism supply, while tourism demand and accessibility have remained crucial for growth together with other traditional engines of growth. Originality/value To the best of authors’ knowledge, none of the current works has considered territorial determinants and tourism indicators inside the same framework analyzing growth in island economies by considering the changes occurred during the crisis explicitly.

Purpose The purpose of this paper is to explore the drivers of economic growth in South Asia region for the period of 1975–2016 using the World Bank data. Design/methodology/approach Panel corrected standard error (static estimation) approach and one-step system generalised method of moments (dynamic estimation) approach are used. Findings Both the static and dynamic estimations indicate that energy use, gross capital formation and remittances are the main drivers of economic growth in South Asian countries. The effects of all these variables are positive and significant. The extent of the effect of energy use is much higher than that of other two variables on the economic growth. A 1 per cent increase in the growth of energy consumption can expedite the gross domestic product growth by approximately 3 per cent in South Asia. However, the key variables, such as trade, government expenditure and foreign direct investment demonstrate no significant effect. Originality/value The current research is original in the sense that it investigated the issue with a new data set using improved econometric techniques. Moreover, in South Asia as a whole, this kind of study is totally absent, particularly with panel data of a large number of years. Furthermore, this study has taken into account the problem of heterogeneity and the biases created by cross-section dependence, which were mostly absent in previous studies. Therefore, the findings of this research are new contributions to the existing literature.

The Impact

PurposeThe primary purpose of this paper is to empirically investigate the impact of educational attainment on crime rates across 33 Indian states over the period 2001 to 2013. This paper also examines the role of various macroeconomic, socio-economic and demographic factors in determining the variation of crimes in India.Design/methodology/approachFirst, this paper provides a representative theoretical model and discusses the possible relationship between crime and education. Second, the paper applies a dynamic panel data (DPD) model to extract more precise, unbiased and reliable estimates of the effect of education in abating different crime rates. The main advantage of using the dynamic panel model is to address the problem of endogeneity in some regressors and capture the time persistent effect of education on crime.FindingsEmpirical findings reveal that a 1% increase in gross enrolment ratio leads to the reduction of total crime by 8%. However, a unique finding identifies a positive association between tertiary education and economic crime. This finding further goes against the general belief that criminals tend to be less educated than non-criminals.Practical implicationsThis paper recommends that instead of punishment and mandatory law enforcement for offenders, increase in government expenditure and different educational attainment ratios can go a long way to combat crime in India, which has posed a serious threat to the stability of society. Furthermore, utilizing the information on offenders' educational attainment in examining the crime rates can be a future research agenda for policymakers.Originality/valueThis study contributes to the empirical debate of ‘crime-education nexus’ by examining the role of education on crime in India. This study is the first of its kind that focuses on the aspects of crime and education more recently and investigates the relationship between crime and education due to the recent changes in educational attainment ratios and crime rate.
