The Role of Individual Intertemporal Transfers in Dynamic TU-Games

Dynamic TU-games are considered which consist of a finite player set, a finite sequence of TU-games and a profile of intertemporal utility functions. At every stage a (restrictively) additive solution is applied to the TU-game, which results in a stream of payoff distributions, evaluated by the intertemporal utility functions of the players. Players are able to transfer payoffs between stages. The strategic possibilities from individual transfers between periods are modeled by a noncooperative game. Conditions under which a Nash equilibrium in this noncooperative game exists, are established. It is shown when a Nash equilibrium in dominant strategies is Pareto optimal.microeconomics ;

On the Static and Dynamic Costs of Trade Restrictions

We analyze the costs of trade restrictions for a small developing economy. Capital goods are only introduced on the market if it is profitable to do so. The economy evolves to a balanced growth path in which income, welfare, and the share of introduced capital goods increase if trade restrictions fall. The adjustment path is asymmetric: an increase in trade restrictions will slow-down economic growth, while a decrease may give rise to a rapid catch-up process. The static costs of trade restrictions are smaller than the dynamic costs if, and only if, it changes the share of introduced capital goods.Growth, development, static and dynamic costs, trade restrictions, new goods.

Structure of the ATP-Synthase from Chloroplasts and Mitochondria Studied by Electron Microscopy

The structure of the ATP-synthase, F0F1 , from spinach chloroplasts and beef heart mitochondria has been investigated by electron microscopy with negatively stained specimens. The detergent-solubilized ATP-synthase forms string-like structures in which the F0 parts are aggregated. In most cases, the F, parts are arranged at alternating sides along the string. The F0 part has an approximate cylindrical shape with heights of 8.3 and 8.9 nm and diameters of 6.2 and 6.4 nm for the chloroplast and mitochondrial enzyme, respectively. The F, parts are disk-like structures with a diameter of about 11.5 nm and a height of about 8.5 nm. The F, parts are attached to the strings, composed of Fn parts, in most cases, with their smallest dimension parallel to the strings. The stalk connecting F0 and F, has a length of 3.7 nm and 4.3 nm and a diameter of 2.7 nm and 4.3 nm for the chloroplast and mitochondrial enzyme, respectively

On the effect of risk aversion in bimatrix games

Nash equilibria with identical supports are compared for bimatrix games that are different with respect to the risk aversion of player 2. For equilibria in 2 by 2-bimatrix games and for equilibria with efficient supports in coordination games it is established for which cases increased risk aversion of player 2 benefits or hurts player 2.microeconomics ;

On the effect of risk aversion in two-person, two-state finance economies

The effect of replacing an agent in a two-person two-state finance economy by a more risk averse agent is studied. It is established under which conditions the other agent benefitsor looses in equilibrium from dealing with a more risk averse agent. If one agent becomes more risk averse, then the equilibrium allocation moves towards that agent''s certainty line. Whether or not that is beneficial for the other agent, depends on the location of the endowment point.microeconomics ;

WP 103 - Separate, joint or integrated?

This paper analyses the integration of active labour market policies for two groups of unemployed from a theoretical perspective. In general a model with only one type of agent performs better than a model with two types of agents. If there are two types of agents part of the effort of one agent leaks away to the other agent and decreases the incentives to get the unemployed back to work. A model where two agents work together and serve both types of unemployed performs even worse. This is because they are only partially compensated for their effort, which decreases the incentives to get the unemployed back to work even more.

Upconversion of a relativistic Coulomb field terahertz pulse to the near infrared

We demonstrate the spectral upconversion of a unipolar subpicosecond terahertz (THz) pulse, where the THz pulse is the Coulomb field of a single relativistic electron bunch. The upconversion to the optical allows remotely located detection of long wavelength and nonpropagating components of the THz spectrum, as required for ultrafast electron bunch diagnostics. The upconversion of quasimonochromatic THz radiation has also been demonstrated, allowing the observation of distinct sum- and difference-frequency mixing components in the spectrum. Polarization dependence of first and second order sidebands at ωopt±ωTHz, and ωopt±2ωTHz, respectively, confirms the χ(2) frequency mixing mechanism

Quantifying Non-Tariff Measures for TTIP. Paper No. 12 in the CEPS-CTR project ‘TTIP in the Balance’ and CEPS Special Report No. 116/July 2015

This paper provides an overview of methods employed to quantify non-tariff measures (NTMs) and then analyses their differences and looks at what these mean for the Transatlantic Trade and Investment Partnership (TTIP) negotiations. The authors find several similarities in the approaches taken. Because all studies conclude that NTMs matter, they argue that policy-makers are right to focus on ‘regulatory cooperation’ in TTIP. Given the significant differences in NTMs across sectors, policy-makers are urged to dive deep into sector-specific elements of NTMs and focus on those sectors where the largest potential gains can be made (i.e. where NTMs are highest, such as in agriculture, automobiles, steel, textiles and insurance services). An area identified for further research is the fact that unlike trade taxes (i.e. tariffs), regulatory barriers to trade are not generally targeted as the primary policy objective, but rather stem from other strategic policy concerns such as consumer safety and/or social and environmental protection. This element should be further investigated
