Die Hauptthese dieser Dissertation ist, dass Nord-Sotho keinen obligatorischen Gebrauch von grammatischen Mitteln zur Markierung von Fokus macht, weder in der Syntax noch in der Prosodie oder Morphologie. Trotzdem strukturiert diese Sprache eine Äußerung nach informationsstrukturellen Aspekten. Konstituenten, die im Diskurs gegeben sind, werden entweder getilgt, pronominalisiert oder an den rechten oder linken Satzrand versetzt. Diese (morpho-)syntaktischen Prozesse wirken so zusammen, dass die fokussierte Konstituente oft final in ihrem Teilsatz erscheint. Obwohl die finale Position keine designierte Fokusposition ist, ist das Wissen um diese Tendenz doch entscheidend für das Verständnis einer morphologischen Alternation, die in Nord-Sotho am Verb erscheint und die in der Literatur im Zusammenhang mit Fokus diskutiert wurde.
Obwohl also ein direkter grammatischer Ausdruck von formaler F(okus)-Markierung im Nord-Sotho fehlt, ist F-Markierung trotzdem entscheidend für die Grammatik dieser Sprache: Fokussierte logische Subjekte können nicht in kanonischer präverbaler Position erscheinen. Sie erscheinen stattdessen entweder postverbal oder in einem Spaltsatz, abhängig von der Valenz des Verbs. Obwohl Nord-Sotho bei Objekten im Gebrauch von Spaltsätzen eine Korrespondenz von komplexer Form mit komplexer Bedeutung zeigt, gilt diese Korrespondenz nicht für logische Subjekte.
Die vorliegende Dissertation modelliert die oben genannten Ergebnisse im theoretischen Rahmen der Optimalitätstheorie (OT). Syntaktischer in situ Fokus und die Abwesenheit von prosodischer Fokusmarkierung können mit unkontroversen Beschränkungen erfasst werden. Für die Ungrammatikaliät fokussierter logischer Subjekte in präverbaler Position schlägt die vorliegende Arbeit die Modifizierung einer in der Literatur vorhandenen Beschränkung vor, die in Nord-Sotho von entscheidener Bedeutung ist. Die Form-Bedeutungs-Korrespondenz wird, wie andere Phänomene pragmatischer Arbeitsteilung auch, innerhalb der schwach bidirektionalen Optimalitätstheorie behandelt.
One of the dangers of harmonisation and unification processes taking place within the framework of the EU is that they may result in the codification of the lowest common denominator. This is precisely what is threatening to happen in respect of assignment. Referring the transfer of receivables by way of assignment to the law of the assignor’s residence, as article 13 of the Proposal does, would be opting for the most conservative solution and would for many Member States be a step backward rather than forward. A conflict rule referring assignment to the law of the assignor's residence is too rigid to do justice to the dynamic nature of assignments in cross-border transactions and it is unjustly one-sided. It offers no real advantages when compared to other conflict rules; it even has serious disadvantages which make the conflict rule unsuitable for efficient assignment-based cross-border transactions. It is not unconceivable that this conflict rule would even be contrary to the fundamental freedoms of the ECTreaty. The Community legislators in particular should be careful not to needlessly adopt rules which create insurmountable obstacles for cross-border business where choice-of-law by the parties would perfectly do. Community legislation has a special responsibility to create a smooth legal environment for single market transactions.
We study the problem of a policymaker who seeks to set policy optimally in an economy where the true economic structure is unobserved, and policymakers optimally learn from their observations of the economy. This is a classic problem of learning and control, variants of which have been studied in the past, but little with forward-looking variables which are a key component of modern policy-relevant models. As in most Bayesian learning problems, the optimal policy typically includes an experimentation component reflecting the endogeneity of information. We develop algorithms to solve numerically for the Bayesian optimal policy (BOP). However the BOP is only feasible in relatively small models, and thus we also consider a simpler specification we term adaptive optimal policy (AOP) which allows policymakers to update their beliefs but shortcuts the experimentation motive. In our setting, the AOP is significantly easier to compute, and in many cases provides a good approximation to the BOP. We provide a simple example to illustrate the role of learning and experimentation in an MJLQ framework. JEL Classification: E42, E52, E58
It is often claimed that decentralisation is effective for the reduction of poverty due to inherent opportunities for higher popular participation and increased efficiency in public service delivery. This paper is a qualitative assessment of the potential of the Ugandan decentralisation reform for poverty alleviation. The Ugandan government initiated an ambitious decentralisation reform in 1992, which represents an example of full-fledged devolution with the transfer of far-reaching responsibilities to local governments. However, several shortcomings, such as low levels of accountability, insufficient human and financial resources, corruption, patronage, and central resistance to decentralisation, constrain the proper implementation of the reform, putting improvements in participation and efficiency at risk and ultimately jeopardising the intended impact on poverty.
The paper constructs a global monetary aggregate, namely the sum of the key monetary aggregates of the G5 economies (US, Euro area, Japan, UK, and Canada), and analyses its indicator properties for global output and inflation. Using a structural VAR approach we find that after a monetary policy shock output declines temporarily, with the downward effect reaching a peak within the second year, and the global monetary aggregate drops significantly. In addition, the price level rises permanently in response to a positive shock to the global liquidity aggregate. The similarity of our results with those found in country studies might supports the use of a global monetary aggregate as a summary measure of worldwide monetary trends. JEL Classification: E52, F01
We analyse a 2-period competitive insurance market which is characterized by the simultaneous presence of standard moral hazard and adverse selection with regard to consumer time preferences. It is shown that there exists an equilibrium in which patient consumers use high effort and buy a profit-making insurance contract with high coverage, whereas impatient consumers use low effort and buy a contract with low coverage or even remain uninsured. This finding may help to explain why positive profits and the opposite of adverse selection with regard to risk types can sometimes be observed empirically. JEL Classification: D82, G22
Following the neopatrimonialism paradigm, it can be hypothesised that in African states informal politics of the rulers infringe on the collection of taxes and in turn reduce state revenues. This article tests this proposition for the case of Zambia. The main finding is that there is no linear correlation between a neopatrimonial system and the collection of taxes. Neopatrimonial continuity in the country is evidenced by three factors; the concentration of political power, the award of personal favours and the misuse of state resources. Despite this continuity, the revenue performance has increased considerably with the creation of the semi-autonomous Zambia Revenue Authority. This demonstrates that the effect of neopatrimonialism on public policy in the African state is highly context-specific and dependent on the interaction with additional variables. Donor pressure has been the most important in the Zambian case. In order to apply neopatrimonialism for further empirical work on public policy in the African state, these additional variables have to be incorporated into the analysis.
The worldwide diffusion of the good governance agenda and new public management has triggered a renewed focus on state capability and, more specifically, on the capability to raise revenue in developing countries. However, the analytical tools for a comprehensive understanding of the capability to raise revenue remain underdeveloped. This article aims at filling this gap and presents a model consisting of the three process dimensions ‘information collection and processing’, ‘merit orientation’ and ‘administrative accountability’. ‘Revenue performance’ constitutes the fourth capability dimension which assesses tax administration’s output. This model is applied to the case of the Zambia Revenue Authority. The dimensions prove to be valuable not only for assessing the how much but also the how of collecting taxes. They can be a useful tool for future comparative analyses of tax administrations’ capabilities in developing countries.
Demographic change in industrialized nations has been a matter of common interest for some time. The financial implications of an ageing society are also increasingly discussed, particularly with regard to pension systems. The impact of this development on public finances is, however, only gradually being realized and the constitutional framework of public finances in Germany and the European Union just falls short of ignoring it entirely. This paper is a preliminary assessment of the burden of an ageing society under the fiscal law, specifically in respect of prospective entitlements to the public pension system. The first part analyses the provisions of the German constitution on finances (Finanzverfassungsrecht) to identify what rules, if any, exist addressing such (potential) expenditures, which lie in the immediate or very distant future. The second part of the paper analyses the fiscal requirements under European Union law. In the third and final part a few comments on the proposed national pact on stability and the recent moves to amend the German Federal Constitution are presented.
The Land and Water Development Division of the Food and Agriculture Organization of the United Nations and the Johann Wolfgang Goethe University, Frankfurt am Main, Germany, are cooperating in the development of a global irrigation-mapping facility. This report describes an update of the Digital Global Map of Irrigation Areas for the continents of Africa and Europe as well as for the countries Argentina, Brazil, Mexico, Peru and Uruguay in Latin America. For this update, an new inventory of subnational irrigation statistics was compiled. The reference year for the statistics is 2000. Adding up the irrigated areas per country as documented in the report gives a total of 48.8 million ha while the total area equipped for irrigation at the global scale is 278.8 million ha. The total number of subnational units in the inventory used for this update is 16 822 while the number of subnational units in the global inventory increased to 26 909. In order to distribute the irrigation statistics per subnational unit, digital spatial data layers and printed maps were used. Irrigation maps were derived from project reports, irrigation subsector studies, and books related to irrigation and drainage. These maps were digitized and compared with satellite images of many regions. In areas without spatial information on irrigated areas, additional information was used to locate areas where irrigation is likely, such as land-cover and land-use maps that indicate agricultural areas or areas with crops that are usually grown under irrigation.
