| Summary/Abstract |
Whilst concerns about the EU-centric character of EU foreign policy analysis have become more frequent in recent years, a systematic toolbox for diagnosing and remedying this problem is still lacking. This article’s contribution is twofold. First, it proposes a new typology of three approaches to foreign policy analysis, offering conceptual body and nuance to the debate on EU-centrism. The typology can be used for scrutinising existing analyses, as well as for shaping new research projects. Second, this typology is applied in a meta-analysis of post-Lisbon EU foreign policy scholarship: a built-for-purpose dataset of 451 articles was analysed, covering all work on EU foreign policy published in seven key journals for the period 2010–2014, was analysed. It was found that academic work on EU foreign policy wass indeed rife with EU-centric research questions, and, moreover, that this is the case irrespective of either the policy area under study or the focus of the journal.

Debate persists on whether voters hold politicians accountable for corruption. Numerous experiments have examined whether informing voters about corrupt acts of politicians decreases their vote share. Meta-analysis demonstrates that corrupt candidates are punished by zero percentage points across field experiments, but approximately 32 points in survey experiments. I argue this discrepancy arises due to methodological differences. Small effects in field experiments may stem partially from weak treatments and noncompliance, and large effects in survey experiments are likely from social desirability bias and the lower and hypothetical nature of costs. Conjoint experiments introduce hypothetical costly trade-offs, but it may be best to interpret results in terms of realistic sets of characteristics rather than marginal effects of particular characteristics. These results suggest that survey experiments may provide point estimates that are not representative of real-world voting behavior. However, field experimental estimates may also not recover the “true” effects due to design decisions and limitations.

| Summary/Abstract |
The sharp growth in the number of publications examining female involvement in terrorism has produced a valuable but un-integrated body of knowledge spread across many disciplines. In this paper, we bring together 54 publications on female terrorism and use qualitative and quantitative analyses to examine the range of theoretical and methodological approaches in these papers. Using a content analysis, we identify six primary research foci: Portrayal in media, Feminism, Interviews with terrorists, Group roles, Motivation and recruitment, and Environmental enablers. Results revealed a reliance on secondary rather than primary data, narrative rather than statistical comparisons, and descriptions rather than explanations of events.

| Summary/Abstract |
The proposed income distribution effect of financial liberalization has gradually attracted the attention of academic economists, but the research results are inconsistent and even contradictory. This paper presents a quantitative review of these studies. The objectives are to assess the impact of financial liberalization on income inequality and to identify the sources of heterogeneity. A meta-analysis is performed with 23 empirical cross-country studies on the relationship between financial liberalization and income inequality, yielding a total of 556 estimates. We find overall support for the small negative relationship between financial liberalization and income inequality when considering potential publication bias and method heterogeneity. Our results suggest that different impact channels, institutional quality, the measurement used for financial liberalization and income inequality, and the use of different econometric methods are especially effective for explaining the differences in past study findings.

This paper attempts to quantitatively summarize the existing empirical evidence on the effects of energy efficiency policies on energy demand and on the price of associated durable goods, as well as to identify the main factors that systematically affect the estimated impacts. To this end, a meta-regression analysis of the effects of energy efficiency policies is carried out on the basis of an extensive review of the existing literature, selecting those studies that analyze the impact of energy efficiency policies with respect to a business-as-usual setting. Taking into account the econometric problems associated with this type of analysis (intra-class correlation, cross-sectional dependence, publication bias) in pursuit of robust outcomes, the results show that the studies analyzing the effects of energy efficiency policies estimate a significant impact of these policies on energy demand [-10.5%; −8.8%] and the price of related durable goods [7%; 9.6%]. The main factors that influence results are the policy instrument, the targeted sector, the type of country, the analyzed period, the consideration of free-riders, and the type of analysis, data and publication (energy demand); and the sector and analyzed period (price of durables).

Empirical evidence suggests that China has benefited from foreign direct investment (FDI). An important question that remains unanswered is whether China has benefited more from FDI than other countries in general, and other transition and developing countries in particular. This paper investigates this issue by performing a meta-analysis on a sample of 67 country-specific studies yielding 137 observations that have gauged the link between FDI and measures of economic growth. The results suggest that the impact of FDI is, on average, more positively significant for China than for the full sample of countries, but that the difference between China and other transition economies is less clear.

| Summary/Abstract |
Energy poverty has evolved as an important issue of research from academic and policy perspectives during the last two decades. The energy poverty estimates exhibit widespread variations across regions, methodologies and datasets, making the task of energy and development policies challenging. The variations in energy poverty estimates necessitate a systematic and rigorous analysis of these empirical studies to obtain a true measure of energy poverty. The present study conducts a meta-analysis of 30 studies and 103 estimates of energy poverty. On average, 71.1 percent of the population in the overall sample studies has been identified as energy poor. High I-square statistic values suggest heterogeneity bias in the sample studies; therefore, analysis at the subgroup level has been conducted. Meta-regression analysis of overall sample and subgroups has identified type of methodology, citations, impact factor of the journal, regional dummies, average key crude oil price and gross domestic product as significant factors that explain heterogeneity in the energy poverty effect sizes. We recommend inclusion of local and regional factors in assessment of energy poverty for developing a uniform methodology to assess energy poverty across developing economies.

This article conducts a meta-analysis of the effect of military expenditures on growth within a structured analytic framework. We extend the pioneering study of Aynur Alptekin and Paul Levine, by using a much larger sample of studies. Like them we confine our attention to studies that use the share of military expenditure in GDP, the military burden, as the independent variable, but unlike them we include not just those that use the military burden directly, what we call the core sample, but also those that use other functions of it, such as logarithms, differences, etc., which we call the remaining sample. We also consider an overall sample which pools all results. The t-statistic on the coefficient of military burden is used as the dependent variable. Our null hypothesis is that military expenditure has no significant effect on growth and we explain why this is plausible. The estimates are sensitive to the sample and type of data used, estimation method adopted, and the controls included. Overall, the results are consistent with the hypothesis of no effect: the average effect across all studies is close to zero. Certain study characteristics appear significant determinants of the effect of military expenditure on growth, but there does not appear to be a simple pattern and different characteristics were significant in the three samples. This might be a result of data mining to produce a significant result. However, there does not appear to be strong evidence of publication bias towards positive or negative results, perhaps because there is no strong a priori belief in the direction of the effect.

By conducting a meta-analysis of the empirical literature on the net employment effects of renewable energy, we explore the extent to which the reported net employment effects are driven by the applied methodology. We find that the reported conclusions on net employment effects are to a large extent driven by the methodology that is applied, where computable general equilibrium (CGE) and I/O methods that include induced effects and studies that consider only the near future in their study period (up to 2020) are generally less optimistic about net employment creation in the wake of the energy transition. In addition, we found that policy reports have a greater tendency to report a positive net employment effect than academic studies.
