La dimensión participativa en el diseño de políticas urbanas. El caso valenciano
2018
La aparición y proliferación de iniciativas ciudadanas que tienen como objetivo gestionar de forma distinta los recursos públicos en muchas de las grandes capitales de Europa, hace plantearse en qué estado se encuentran las políticas públicas y sobre todo su gestión. Estamos hablando de una serie de iniciativas surgidas de abajo-arriba que han cambiado la forma tradicional de gestionar la ciudad basada en el tradicional enfoque administrativista de arriba-abajo. Recientemente muchos gobiernos, como consecuencia de estas iniciativas, y de la carencia de recursos y capacidades con los que poder afrontar viejos y nuevos retos, están diseñando nuevas políticas de desarrollo urbano que impliquen…
Tax Incentives as a Part of Governments’ Applied Mechanisms for the Third Pension Pillar in Estonia, Latvia, and Lithuania
2020
The main objective of the improvements to public pension systems is to create a balanced three-pillar pension structure and increase public accountability for pension capital formation. Most pension systems are based on the first two pension system pillars – mandatory contributions in the state compulsory unfunded pension scheme and the state-funded or accumulated pension scheme in pension funds. However, the pension level adequacy has been reached by adding the third pension system pillar - voluntary investments in private pension funds. Governments are private pension system policymakers by defining a legal framework and providing tax incentives for voluntary investments for retirement. I…
Physical Load and Preventive Measures in Metal Manufacturing Industry
2020
In today’s advanced work environment, workers are still exposed to ergonomic risks in the work environment and employees are exposed physically hard work that includes moving loads and frequent repetitive movements at fast pace. For the ergonomic risk analysis and workload assessment, three work operations with the high physical activity were selected: the welder’s workplace, the ironing board sorting line and the ironing board’s packing station. Subjective and objective ergonomics research methods were used. Research results show that employees in selected work operations are exposed to a fast work speed and often, monotonous movements at the sorting line and lifting heavy loads at the iro…
Evolution of correlation structure of industrial indices of U.S. equity markets
2013
We investigate the dynamics of correlations present between pairs of industry indices of US stocks traded in US markets by studying correlation based networks and spectral properties of the correlation matrix. The study is performed by using 49 industry index time series computed by K. French and E. Fama during the time period from July 1969 to December 2011 that is spanning more than 40 years. We show that the correlation between industry indices presents both a fast and a slow dynamics. The slow dynamics has a time scale longer than five years showing that a different degree of diversification of the investment is possible in different periods of time. On top to this slow dynamics, we als…
Limit order placement as an utility maximization problem and the origin of power law distribution of limit order prices
2006
I consider the problem of the optimal limit order price of a financial asset in the framework of the maximization of the utility function of the investor. The analytical solution of the problem gives insight on the origin of the recently empirically observed power law distribution of limit order prices. In the framework of the model, the most likely proximate cause of this power law is a power law heterogeneity of traders' investment time horizons .
Scaling laws of strategic behavior and size heterogeneity in agent dynamics
2008
The dynamics of many socioeconomic systems is determined by the decision making process of agents. The decision process depends on agent's characteristics, such as preferences, risk aversion, behavioral biases, etc.. In addition, in some systems the size of agents can be highly heterogeneous leading to very different impacts of agents on the system dynamics. The large size of some agents poses challenging problems to agents who want to control their impact, either by forcing the system in a given direction or by hiding their intentionality. Here we consider the financial market as a model system, and we study empirically how agents strategically adjust the properties of large orders in orde…
Most-Favoured-Nation Treatment, Survival Clauses and Reform of International Investment Law
2016
In the last decade, international investment law has been on a trajectory of rapid evolution with reform high on agenda priorities. Reform requires a reconciliation of competing interests, which is generally so difficult to achieve that it is often unclear whether an option constitutes ‘reform’ or unwanted change. Two specific treaty provisions, the most-favoured-nation (MFN) treatment and survival clauses, can interfere with the reform process and become an impediment to changing the rules of the game. This is particularly true when political will is present. The MFN treatment, a guarantee of non-discrimination present in the quasi-totality of investment treaties, can have far-reaching ram…
Academic and Administrative Tandems in European Projects
2017
International audience; Building and maintaining the sustainability of European projects requires advanced communication and team investment, shared working methods, common decisions and symbiosis in key items such as selection requirement and process, terms of mobility between consortium members or teaching content. It requires jointness in various perspectives, aspects and scales, with their own conditions and challenges. This abstract describes this prerequisite of jointness through the local campus of Le Creusot (University of Burgundy) for our International Programme in Computer Vision and Robotics (VIBOT). The main challenge can be summarized in one single question: How to maintain an…
The importance of management innovation and consultant services on ERP implementation success
2011
Enterprise resource planning (ERP) implementation has been an important activity for improving efficiency. However, an ERP system is a critical investment that can significantly affect future performance of a company. Many ERP projects report an unusually high failure rate. This study empirically investigates the involvement of management consultants in ERP implementation success. The results from our field survey of 134 ERP end-users in Spanish ceramic tile companies show that ERP implementation success significantly depends on the quality of consultant services. The results also indicate the importance of internal management throughout the learning process. Overall, these findings contrib…
Adaptation of Risk Sharing Partnerships (RSP) to New Industries
2020
The aerospace industry has since the 1990s used a partnership model called Risk Sharing Partnerships (RSP) to handle certain challenges faced in the development of new aircrafts. The RSP model allows the client to include key suppliers in the development of a new product, and hence sharing the burden of investment, risk mitigation, as well as the future sales income. This makes it easier to acquire funding for the development of new products and technologies, in addition to accelerating the development process by including key competencies earlier (Buzacott and Peng in Eur J Oper Res 218:656–666, 2012). RSP have raised interest in other industries, which calls for increased knowledge of con…
