ARE IMPACTS OF EARLY INTERVENTIONS IN THE SCANDINAVIAN WELFARE STATE CONSISTENT WITH A HECKMAN CURVE? A META‐ANALYSIS

“Early intervention” has been a mantra in recent debates about human capital investment. Strong theoretical models motivate this focus by predicting that investment in children is most cost‐effective when they are young. The “Heckman curve” summarizes this idea visually (Heckman, 2006). However, hardly any reviews scrutinize this hypothesis empirically in modern welfare states such as those in Scandinavia that already invest heavily during early childhood. Any such review is ideally based on interventions conducted as randomized controlled trials (RCTs), set in the same welfare state, and comparable across ages through cost‐standardized effects. This meta‐analysis assembles cost‐standardized effect estimates from 10 RCTs, including a total of 18 intervention arms and 30,578 participants (aged 1.5–24 years), conducted by the same research center in the Scandinavian welfare state of Denmark. These interventions show significant effects relative to their costs, despite the large baseline investment level. Interventions targeted at younger children tend to produce larger effects, consistent with the Heckman curve. However, variation in the effect size within age groups is as large as it is across age groups. This indicates that both the quality and timing of investments matter and that “early interventions” are not necessarily superior to later interventions.     

Enhancing Access to the Global Food Manufacturing Value Chain: The Role of a Food Safety Technical Regulation in Ghana

Demonstrating compliance with food safety requirements of the global food economy is a prerequisite for access. This article presents an overview of the governance within global value chains and their impact on the prospects of developing countries accessing and participating in the global food manufacturing value chain. Based on fieldwork undertaken in Ghana, the article investigates the issues that hinder compliance of the Ghanaian food manufacturing sector with the basic requirements of food safety and investigates the potential role of a technical regulation in enhancing compliance, and therefore participation, in the global food manufacturing economy.     

Capital Flows and Economic Growth in Ghana

ABSTRACT

The study examines the differential effects of capital flows on economic growth in Ghana over the period 1970–2014 using autoregressive distributed lag (ARDL). Breakpoint unit root tests are employed to cater for structural change and breaks in time series. Afterwards, these break dates are fed into the ADRL model as dummy variables to allow for the computation of a more robust cointegrating vector. The findings indicate that in both the short and long run capital flows (i.e. FDI, aid, and external debt) have negative effects on economic growth. However, remittances exhibit positive insignificant elasticity in all the regressions. Further, the empirical results show that while the impact of trade, gross capital formation and population growth on growth are mixed, that of inflation is negative. The results of the study are consistent with the idea that the impact of capital flows in Africa has been exaggerated.     

An Analysis of the Effect of Culture and Religion on Perceived Corruption in a Global Context

This study examines the role of both religion and culture [as measured by the cultural clusters of countries in the GLOBE study of House et al. (Culture, Leadership, and Organizations: The GLOBE Study of 62 Societies, 2004)] on the levels of perceived corruption. Covering the period from 2000 to 2010, the study uses three different measures of perceived corruption: (1) the World Bank’s Control of Corruption measure, (2) Transparency International’s Corruption Perceptions Index, and (3) Heritage Foundation’s Freedom from Corruption Index. A system of three simultaneous equations is used, with the jointly endogenous variables being (a) perceived corruption, (b) perceived government legitimacy, and (c) perceived government effectiveness. The results show that both cultural and religious differences are incrementally related to perceived corruption, even after controlling for other economic and political factors. Specifically, relative to the Protestant Christian religion, the non-Protestant Christian religion, the Islamic religion, and Other Religion/No Religion are positively associated with higher corruption (or negatively with anti-corruption), but the Buddhist and Hindu religions appear to be not significantly different from the Protestant Christian religion. On the cultural side, compared to the Anglo-Saxon cultural tradition, the other European clusters are incrementally positively associated with higher corruption, but this tendency is offset by more effective political governance, thus leading in the case of the German and Nordic cultures to levels of corruption not statistically different from the Anglo cluster. All the non-European cultural clusters are associated with significantly higher corruption tendencies, but the overall effect is mitigated partially by either greater perceived political legitimacy (Latin-American, Middle-Eastern, Caribbean, and Pacific Islander), or greater political effectiveness (Confucian and South-East Asian).     

A reply to Randall E. LaSalle: “The civil justice system and going-concern audit reports: Comments on ‘Auditors’ decision-making under going-concern uncertainties in low litigation-risk environments: Evidence from Hong Kong’ ”

In a dissent from the conclusion reached in Lam and Mensah [Lam, K, Mensah, Y.M., 2006. Auditors’ decision-making under going-concern uncertainties in low Litigation-risk environments: Evidence from Hong Kong. Journal of Accounting and Public Policy, 25 (6), 706–739], Lasalle has proposed a number of alternative plausible explanations for our findings that Hong Kong auditors issued disclaimer of opinions in a manner associated with the eventual outcome to the clients. We examine these explanations and attempt to relate them to relevant empirical evidence in the literature. We find that none of his plausible explanations is consistent with the limited empirical evidence available. Thus, we continue to believe that a high litigation-risk environment is not a necessary pre-requisite for high quality audits.     

Knowledge of entrepreneurial support and entrepreneurial intention in the rural provinces of South Africa

The purpose of this study was to investigate whether knowledge about government entrepreneurial support and entrepreneurial support institutions and their services have an influence on entrepreneurial intention and its antecedents. The study was carried out by means of a cross-sectional survey using a structured questionnaire. The sample consisted of 355 final-year commerce students from two universities located in two of South Africa’s most rural provinces, namely the Eastern Cape and Limpopo. The Statistical Package for the Social Sciences was used to analyse the data. The results indicate that the respondents could hardly access information about entrepreneurial support offered by the government and support services available, and had a very low level of knowledge about these support services. The findings revealed some significant relationships between the knowledge of entrepreneurial support and entrepreneurial intention, perceived behavioural control, subjective norms and entrepreneurial self-efficacy.
