    New Journal Article on Privatization in the Latin American Power Sector

    LoewensteinWSadik ZadaTwo IEE members, Prof. Dr. Wilhelm Löwenstein, Dr. Elkhan Richard Sadik-Zada, and a former RUB student and currently European Investment Fund and CED fellow Mattia Ferrari published together an article in the International Journal of Energy Economics and Policy, Volume 8, No.1 (pp. 95-103):

    Privatization and the Role of Sub-National Governments in the Latin American Power Sector: A Plea for less Subsidiarity?

    In this paper, they explore the cross-national impact of privatization in the network industries on the access to network services. They focus on the assessment of the electricity sector in 20 Latin American countries and analyze the time series between 1985 and 2010. To control for the relevance of the subsidiarity (social commons) argument they assess the interaction between commodification and the role of the sub-national governments in the power sector. Privatization has a statistically significant positive effect on the level of electricity access. In the absence of federalism, privatization in the electricity sector has a greater impact on electrification than is the case with federalist government system. Federalism has a positive impact on the electricity access if electricity is generated and supplied mainly by the state-owned enterprises. Another interesting finding is the relationship between the degree of subsidiarity and electrification: A higher degree of subsidiarity has a negative effect on the electrification. This could be a result of the increasing transaction costs and rent-seeking behavior in the decentralized settings. The study complements the existing literature by analyzing the privatization reform from the subsidiarity perspective

    Two New Journal Articles by Britta Niklas

    IEE member Britta Niklas published two articles (one as a co-author) in the Journal of Wine Economics, Volume 12/2017, No. 4:

    2018 01 JournalofWineEconomicsBritta Niklas: Impact of Annual Weather Fluctuations on Wine Production in Germany (pages 436 - 445):

    This paper analyzes the impact of annual weather fluctuations on the total output of wine and on the share of output of different wine-quality categories in Germany, using a set of wine data from all thirteen German wine regions and daily weather data taken from regional weather stations. The empirical analysis suggests that rising average temperatures have a significantly positive impact on the total output of wine as well as on the output shares of wine in higher- quality categories. The number of freezing days appears to be detrimental to overall produc- tion; precipitation during the growing season impairs higher-quality wines in particular. (JEL Classifications: Q21, Q13)

    Britta Niklas, Karl Storchmann & Nick Vink: Fairtrade Wine Price Dispersion in the United Kingdom (pages 446 - 456):

    This paper analyzes wine price dispersion in the United Kingdom. In particular, we are inter- ested in examining whether Fairtrade wines are different from non-Fairtrade wines. Because Fairtrade wines serve an additional social purpose, one may think that consumers search less aggressively for the outlet with the lowest price, thus allowing for a larger price dispersion than for regular wines. We draw on data for about seven thousand wines from South Africa, Fairtrade and non-Fairtrade, sold in the United Kingdom between 2007 and 2012. In a first step, we run a hedonic regression model explaining the wine prices using Ordinary Least Squares (OLS) and Two-Stage Least Squares (2SLS) Instrumental Variable (IV) approaches. In the next step, we regress the squared residuals from the first step on a Fairtrade 0-1 dummy-variable. When using the squared residuals from the OLS model, we find that Fairtrade is a negative determinant of price dispersion. Therefore, Fairtrade wines exhibit a sig- nificant lower price dispersion than the comparison group. When using the squared residuals from the IV model, we find mixed results and suspect the presence of a substantial bias due to weak instruments. Finally, in order to avoid IV pitfalls, we ran Fairtrade and Non- Fairtrade wines in separate equations. We find support for the OLS results, i.e., Fairtrade wines appear to exhibit lower price dispersion than their non-Fairtrade counterparts. Whether this is due to consumer search is a priori unclear.

    New Journal Article by PhD student Amr Khafagy

    KhafagyAn article of IEE PhD student Amr Khafagy: "Regulation, supervision and deposit insurance for financial cooperatives: an empirical investigation" has been published in the Annals of Finance (online first)

    This paper analyses the impact of different regulation and supervision approaches, as well as deposit insurance schemes, on the development of financial cooperatives in developing countries, using random and fixed effects estimators. Information on laws regulating financial cooperatives, the supervisory approaches adopted, and deposit insurance schemes in sixty-five developing countries were collected—mostly—from original legislations for the period 1995–2014. Key findings suggest that indicators of financial cooperative development are positively correlated with the existence of a specialized regulation; supervision under non-bank financial supervisory authorities; and the presence of deposit insurance schemes, while general cooperative society’s regulations and banking regulations are negatively correlated with financial cooperatives’ indicators. These results are robust after controlling for economic and institutional factors as well as potential endogeneity bias.

    New Journal Article by PhD student Themba Nyasulu

    An article of IEE Phd student Themba Nyasulu: "Harnessing Economic Impacts of Migrant Remittances for Development in Sub-Saharan Africa: A Critical Review of the Literature" has been published in the African Human Mobility Review (AHMR).

    The recent rise in migrant remittances across Sub-Saharan Africa is one of the important issues currently dominating economic policy discourse in the region. Given the large volume of remittance flows, it is obvious that they have important positive and negative economic effects on the individual families and economies that receive them. Therefore, this paper critically examines channels through which remittance transfers affect microeconomic and macroeconomic activity, and suggests policy options available to Sub-Saharan African countries in terms of harnessing their development potential. The paper affirms that prospects for remittances to facilitate economic development remain high provided that recipient countries put in place institutional frameworks capable of mitigating the malign effects and enhancing the benign effects of remittances.

    Dr. Annika Engelbert Published Her Doctoral Thesis

    Engelbert ThesisAnnika Engelbert: Public Procurement Law in Sub-Saharan Africa. A Means to Curb Corruption?

    Baden-Baden: Nomos Verlagsgesellschaft, 2017. - 289 S. - ISBN 978-3-8487-4026-0
    (Recht und Verfassung in Afrika – Law and Constitution in Africa, Vol. 31)

    Public procurement is a core government activity that is highly prone to corruption. Why, despite joint efforts of national governments and the international donor community to strengthen statutory frameworks, are public procurement systems in Sub-Saharan Africa still insufficiently equipped to prevent corruption? It is the purpose of the book to advance Law and Development research by (a) assessing the effectiveness of institutional means to curb procurement-related corruption in Tanzania, Kenya, and Uganda; (b) treating law as a means to foster development, and (c) applying qualitative research methods to establish causal mechanisms between law and the social phenomenon of corruption. The book shows that while procurement systems are on paper well suited to serve as anti-corruption instruments, implementation gaps are significant; thus, 'law in books' and 'law in action' differ to a large extent. The reasons are unearthed on the political, institutional, and individual level.

    New Journal Article by Raffael Beier

    Raffael Beier: Tunis und Casablanca - Stadtentwicklungspolitiken zwischen "Worlding" und Sozialverträglichkeit, in: inamo 89, Informationsprojekt Naher und Mittlerer Osten, Jg. 23, Frühling 2017, S. 24-28

    2011 gerieten die arabischen Städte als Orte der Revolte in den Fokus der Weltöffentlichkeit. Dieser Artikel widmet sich dem engen Verhältnis von Stadt und Protest und fragt, inwiefern die Stadtentwicklungspolitik in Tunis und Casablanca auf den Arabischen Frühling reagiert hat. Neben Versuchen der strukturellen Erneuerung der Stadtentwicklungspolitik in Tunesien und steigender Bedeutung der sicherheits- und stabilitätspolitischen Dimension in der Stadtplanung sind zuletzt verstärkt Kontinuitäten, insbesondere im Hinblick auf den Bau von Großprojekten, zu beobachten.

    New Article by Johannes Norpoth

    Johannes Norpoth: The Mutually Agreed Solution (MAS) between Indonesia and the United States (US) in US – Clove Cigarettes: A Case of Efficient Breach (or Power Politics)?

    The MAS to the US – Clove Cigarettes case between the US and Indonesia evokes the idea of the WTO dispute settlement system (DSS) allowing for efficient breach since the case was declared settled based on mutual commitments of the two parties, while the original violation by the US remains in place. The paper first discusses whether MAS are a means through which WTO law allows such flexibility, concluding that such a view is tenable despite valid objections. Then, it inquires whether the MAS found between Indonesia and the US can be considered as a situation of efficient breach. In this context, the paper analyses the mutual commitments of the US and Indonesia with specific attention to the potential role of power in the settlement. The paper argues that from a legal perspective the MAS between Indonesia and the US cannot be considered a case of efficient breach, although politically the situation established through the MAS resembles a situation of efficient breach. The paper finds that power imbalances played a role in the settlement and suggests that the case study of this specific MAS highlights systemic risks in the current handling of WTO dispute settlement through MAS.

    Dimensionen und Bestimmungsfaktoren der HIV/AIDS-bezogenen Stigmatisierung in der Republik Südafrika: Ergebnisse einer empirischen Untersuchung unter Studenten in der Metropolregion Kapstadt.
    Stigmatisierungsprozesse gegenüber Menschen mit HIV/AIDS stellen ein elementares Hindernis im Kampf gegen die Immunschwächekrankheit dar. In Südafrika fielen diese in der Vergangenheit so drastisch aus, dass Betroffene das Bekanntwerden ihrer HIV-Infektion mit dem Leben bezahlt haben. Die vorliegende Arbeit stellt eine Ursachenanalyse HIV/AIDS-bezogener Stigmatisierungsprozesse in der südafrikanischen Gesellschaft dar. Basierend auf sozialwissenschaftlichen Theorien und empirischen Vorkenntnissen wird ein Erhebungsinstrument zur Erfassung stigmatisierender Einstellungen entwickelt. ...

    Oil Abundance and Economic Growth.
    This book deals with the role of oil abundance in economic growth. The major theoretical contribution of the analysis is the transformation of the rentier state theory into the language of mathematical economics. The mathematical formalization of the rentier state theory enables a more sophisticated analytical tool for the assessment of the role of nonrenewable resource revenues in economic growth and institutional dynamics. The embedding of the elements of a rentier state into the labor surplus economy framework leads to grave consequences as reflected in the quantitative part of the survey. The augmented labor surplus economy model shows that both the political economy and the purely economic causes of the resource curse can have similar effects on the resource allocation in the affected nation. ...

    Journal Article by Amr Khafagy

    Amr Khafagy, PhD IDS student at the IEE, published an article in the Journal of Institutional Economics:
    "Political institutions and financial cooperative development".

    This paper analyses the influence of political institutions on the development of financial cooperatives. It proposes a political economy theory where autocratic regimes deliberately oppose the development of a well-functioning financial cooperative sector to maintain their political influence, and prevent the formation of strong pressure groups that can threaten the current political status quo and reduce the governing elites’ economic benefits from underdeveloped and exclusive financial sector. Using panel data from 65 developing countries from 1995–2014, the results show that democracy, political rights and civil liberties promote financial cooperative development. These results are robust in controlling for endogeneity as well as other economic and institutional factors.
