Distributed ledger technology especially in the form of publicly coordinated validation networks such as Ethereum and Bitcoin with their own monetary circles provide for a revealing litmus test for current financial regulatory schemes. The paper highlights the interrelation between distributed coordination and the emission of virtual currency to make sense of the function of the new monetary phenomenon. It then argues for the regulation of financial services on the ground of the technology to ensure integrity standards. In this respect, it is useful to gear the development of a regulatory scheme towards the existing financial regulatory principles. However, future measures of the regulators must take the distributed nature of the platforms into account by relying on a “regulated self-regulation” of the community. Finally, the article focuses on the shortcomings of the current EU regulatory regimes, especially the regulation frameworks regarding financial services, payment services and electronic money.
Many Americans claim Social Security benefits early, though this leaves them with lower benefits throughout retirement. We build a lifecycle model that closely tracks claiming patterns under current rules, and we use it to predict claiming delays if, by delaying benefits, people received a lump sum instead of an annuity. We predict that current early claimers would defer claiming by a year given actuarially fair lump sums, and the predictions conform with respondents’ answers to a strategic survey about the lump sum. In other words, such a reform could provide an avenue for encouraging delayed retirement without benefit cuts or tax increases. Moreover, many people would still defer claiming even for smaller lump sums.
Implications of money-back guarantees for individual retirement accounts: protection then and now
(2019)
In the wake of the financial crisis and continued volatility in international capital markets, there is growing interest in mechanisms that can protect people against retirement account volatility. This paper explores the consequences for savers’ wellbeing of implementing market-based retirement account guarantees, using a life cycle consumption and portfolio choice model where investors have access to stocks, bonds, and tax-qualified retirement accounts. We evaluate the case of German Riester plans adopted in 2002, an individual retirement account produce that includes embedded mandatory money-back guarantees. These guarantees influenced participant consumption, saving, and investment behavior in the higher interest rate environment of that era, and they have even larger impacts in a low-return world such as the present. Importantly, we conclude that abandoning these guarantees could enhance old-age consumption for over 80% of retirees, particularly lower earners, without harming consumption during the accumulation phase. Our results are of general interest for other countries implementing default investment options in individual retirement accounts, such as the U.S. 401(k) defined contribution plans and the Pan European Pension Product (PEPP) recently launched by the European Parliament.
This paper examines how networks of professional contacts contribute to the development of the careers of executives of North American and European companies. We build a dynamic model of career progression in which career moves may both depend upon existing networks and contribute to the development of future networks. We test the theory on an original dataset of nearly 73 000 executives in over 10 000 _rms. In principle professional networks could be relevant both because they are rewarded by the employer and because they facilitate job mobility. Our econometric analysis suggests that, although there is a substantial positive correlation between network size and executive compensation, with an elasticity of around 20%, almost all of this is due to unobserved individual characteristics. The true causal impact of networks on compensation is closer to an elasticity of 1 or 2% on average, all of this due to enhanced probability of moving to a higher-paid job. And there appear to be strongly diminishing returns to network size.
Im Frühjahr 2018 wurde innerhalb des vom Bundesministerium für Bildung und Forschung geförderten Projektes „QuartierMobil“ eine Haushaltsbefragung im innenstadtnahen Stadtteil Frankfurt-Bornheim durchgeführt (N = 1027). Für die Stichprobenauswahl wurden das Random-Route-Verfahren und die Last-Birthday-Methode angewendet. Der Fragebogen wurde in Abstimmung mit den Projektpartner*innen, dem Referat Mobilitäts- und Verkehrsplanung der Stadt Frankfurt sowie dem Planungsbüro Planersocietät, entwickelt. Ziel der Befragung war es, die Dynamiken und Präferenzen der Bewohnenden des Quartiers hinsichtlich ihrer Alltagsmobilität, Verkehrsmittelnutzung und Einstellungen zu Konfliktsituationen zu erhalten. Der Schwerpunkt der Befragung lag auf dem Parken im urbanen Quartier und möglichen Gestaltungsoptionen des städtischen Parkraummanagements hin zu einer nachhaltigeren Mobilität und einer Erhöhung der Aufenthalts- und Lebensqualität im Quartier.
Revisiting the stealth trading hypothesis: does time-varying liquidity explain the size-effect?
(2019)
Large trades have a smaller price impact per share than medium-sized trades. So far, the literature has attributed this effect to the informational content of trades. In this paper, we show that this effect can arise from strategic order placement. We introduce the concept of a liquidity elasticity, measuring the responsiveness of liquidity demand with respect to changes in liquidity supply, as a major driver for a declining price impact per share. Empirical evidence based on Nasdaq stocks strongly supports theoretical predictions and shows that the aspect of liquidity coordination is an important complement to rationales based on asymmetric information.
In this paper, we investigate the relation between buildings' energy efficiency and the probability of mortgage default. To this end, we construct a novel panel dataset by combining Dutch loan-level mortgage information with provisional building energy ratings that are calculated by the Netherlands Enterprise Agency. By employing the Logistic regression and the extended Cox model, we find that buildings' energy efficiency is associated with lower likelihood of mortgage default. The results hold for a battery of robustness checks. Additional findings indicate that credit risk varies with the degree of energy efficiency.
The synchronous pi-calculus is translated into a core language of Concurrent Haskell extended by futures (CHF). The translation simulates the synchronous message-passing of the pi-calculus by sending messages and adding synchronization using Concurrent Haskell's mutable shared-memory locations (MVars). The semantic criterion is a contextual semantics of the pi-calculus and of CHF using may- and should-convergence as observations. The results are equivalence with respect to the observations, full abstraction of the translation of closed processes, and adequacy of the translation on open processes. The translation transports the semantics of the pi-calculus processes under rather strong criteria, since error-free programs are translated into error-free ones, and programs without non-deterministic error possibilities are also translated into programs without non-deterministic error-possibilities. This investigation shows that CHF embraces the expressive power and the concurrency capabilities of the pi-calculus.
The focus of this paper are space-improvements of programs, which are transformations that do not worsen the space requirement during evaluations. A realistic theoretical treatment must take garbage collection method into account. We investigate space improvements under the assumption of an optimal garbage collector. Such a garbage collector is not implementable, but there is an advantage: The investigations are independent of potential changes in an implementable garbage collector and our results show that the evaluation and other similar transformations are space-improvements.
