Quality change and other influences on measures of export prices of manufactured goods
No full textMeasures of long-term trends in world export prices for manufactured goods, and in the terms of trade between manufactured goods and primary products, are sensitive to many choices in methods for weighting indexes, base periods, and (most important) changes in quality. For example: 1) wieghting products by their importance in exports to developing countries, rather than by their importance in exports to all countries, reduces the estimated rate of increase in prices for manufactured goods by about 0.1 or 0.2 percentage points a year; 2) a shift in weights from those of an early year (1963) to those of a recent year (1986) reduces the rate of increase in prices by about a third of a percentage point a year; 3) export price indexes with weights of Japanese exports grow about 0.2 to 0.4 percentage points a year less than one weighted by the U.S. export composition, with the larger difference for indexes based on 1963 weights; 4) adjusting the price index for exports of machinery and transport equipment for quality changes not accounted for in the price indexes reduces the rate of increase for those products by about one percentage point a year, and that adjustment for only those products reduces the estimated rate of increase in prices for all manufactures by about half a percentage point a year. Conservative estimates of the bias in the most commonly used measure of export prices of manufactured products - the U.N. export unit value index for manufactures - suggest that this measure overstates the long-run rise in prices for manufactured goods by more than half a percentage point a year, probably one percentage point or more. If so, there has been no long-term trend toward the prices of manufactured goods rising faster that prices for primary products. However, no conceivable estimate of bias in measures of prices for manufactured goods would reverse the picture of declining relative prices for primary products in the 1980s.Access to Markets,Markets and Market Access,Economic Theory&Research,Environmental Economics&Policies,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT
A Note on the Equivalence of Rationalizability Concepts in Generalized Nice Games
No full textMoulin (1984) describes the class of nice games for which the solution concept of point-rationalizability coincides with iterated elimination of strongly dominated strategies. As a consequence nice games have the desirable property that all rationalizability concepts determine the same strategic solution. However, nice games are characterized by rather strong assumptions. For example, only single-valued best responses are admitted and the individual strategy sets have to be convex and compact subsets of the real line R1. This note shows that equivalence of all rationalizability concepts can be extended to multi-valued best response correspondences. The surprising finding is that equivalence does not hold for individual strategy sets that are compact and convex subsets of Rn with n>1.

Modeling the Use of Nonrenewable Resources Using a Genetic Algorithm
No full textThis paper shows, how a genetic algorithm (GA) can be used to model an economic process: the interaction of profit-maximizing oil-exploration firms that compete with each other for a limited amount of oil. After a brief introduction to the concept of multi-agent-modeling in economics, a GA-based resource-economic model is developed. Several model runs based on different economic policy assumptions are presented and discussed in order to show how the GA-model can be used to gain insight into the dynamic properties of economic systems. The remainder outlines deficiencies of GA-based multi-agent approaches and sketches how the present model can be improved.
On toric h -vectors of centrally symmetric polytopes
No full textAbstract.: We prove tight lower bounds for the coefficients of the toric h-vector of an arbitrary centrally symmetric polytope generalizing previous results due to R. Stanley and the author using toric varieties. Our proof here is based on the theory of combinatorial intersection cohomology for normal fans of polytopes developed by G. Barthel, J.-P. Brasselet, K. Fieseler and L. Kaup, and independently by P. Bressler and V. Lunts. This theory is also valid for nonrational polytopes when there is no standard correspondence with toric varieties. In this way we can establish our bounds for centrally symmetric polytopes even without requiring them to be rationa
Uniqueness Conditions for Point-Rationalizable
No full textThe unique point-rationalizable solution of a game is the unique Nash equilibrium. However, this solution has the additional advantage that it can be justified by the epistemic assumption that it is Common Knowledge of the players that only best responses are chosen. Thus, games with a unique point-rationalizable solution allow for a plausible explanation of equilibrium play in one-shot strategic situations, and it is therefore desireable to identify such games. In order to derive sufficient and necessary conditions for unique point-rationalizable solutions this paper adopts and generalizes the contraction-property approach of Moulin (1984) and of Bernheim (1984). Uniqueness results obtained in this paper are derived under fairly general assumptions such as games with arbitrary metrizable strategy sets and are especially useful for complete and bounded, for compact, as well as for finite strategy sets. As a mathematical side result existence of a unique fixed point is proved under conditions that generalize a fixed point theorem due to Edelstein (1962).
"The poetics of everyday life": the sublime as an aesthetic force in the lyric poetry of Emily Dickinson and Annette Von Droste-Hülshohh
No full textEmily Dickinson's and Annette von Droste-Hülshoff's poetry of the everyday is transfigured by the sublime. The dissertation uses close reading to stress form, suggesting that poetic practice cannot fold into the group mind-set of much late twentieth-century feminist literary criticism which tended to analyze women's writing in isolation as symptomatic of issues pertaining to gender. The dissertation places these writers firmly in their cultural and historical contexts, establishing parallels between Dickinson's and Droste's milieus. Both authors demonstrate aspects of late-Romanticism / Biedermeier-Romanticism, a reaction or taming of early-Romantic excesses. Thus the dissertation points the direction of women's writing away from gendered formations exclusively, to broader concerns pertaining to culture and society which include but are not limited to gender contingencies.Ph.D.Includes abstractVitaIncludes bibliographical referencesby Susanne Silvia Navarr
The political economy of hedge fund regulation
No full textThe currency crises and episodes of market unrest of the 1990s sparked a series of regulatory initiatives to reform the Global Financial Architecture. One of these initiatives tackled the activities of hedge funds, a type of investment vehicle that was frequently cited as one of the causes of these crises. The key research question of this thesis is why efforts to regulate an apparently destabilising aspect of financial markets failed, despite the setting up of an ad hoc forum at the international level (the Financial Stability Forum) and various domestic initiatives in the US, the country where most hedge funds operate.
The thesis develops a theoretical framework that examines this regulatory inaction through three explanatory models. The first model draws upon mainstream economic accounts and argues that the empirical evidence did not justify more interventionist public regulation of hedge funds. The second model assumes that a form of relational power has been exercised at the regulatory table: those actors with an interest in leaving hedge funds unregulated prevailed over those that favoured a more mandatory approach. The third model argues that it was not just relational power that determined outcomes, but mainly the power of the structure of meaning within which discussions took place and problems were framed. This structure of meaning led to a particular formulation of the problem at stake, which excluded other concerns and actors from the regulatory agenda.
Each model is analysed for its policy implications. The first model leads to regulatory solutions that rely upon private actors' due diligence and self-assessment of risk. The second model leads to policy options that favour a greater inclusion of developing countries and other stakeholder groups in decision-making processes in global finance. The third model leads to a rethinking of the very tenets of financial market regulation and of the financial theories used to explain and govern the market. The thesis argues that the third model is better able to grasp the complexity of power beyond the seemingly technical nature of financial regulation. For this reason, it is deemed more suitable to provide policy solutions that challenge the current neo-liberal framework of regulation
