Impact of Global Economic Crisis on the European Welfare States

2013

The global economic crisis and the subsequent weaker growth are putting under pressure welfare states in the EU. This paper aims at discussing the effects of the crisis at the social level and at identifying whether the classic European welfare state models (Nordic, Continental, Anglo-Saxon and Mediterranean) are still valid in today’s economy. An answer will be tried using the mathematical tool of principal components analysis. The results will be observed in graphs where the states taken into consideration respect the classical welfare models or they regroup themselves into new circumstances’ adapted models. Even though the classical welfare models are generally still checked up with the …

Notional defined contribution pension schemes: Why does only Sweden distribute the survivor dividend?

2015

The aim of this paper is to analyse the role of the survivor dividend in notional defined contribution (NDC) pension schemes. At present, this feature can only be found in the Swedish defined contribution scheme. We develop a model that endorses the idea that the survivor dividend has a strong basis for enabling the NDC scheme to achieve financial equilibrium and that not including the dividend is a non-transparent way of compensating for increases in longevity and/or legacy costs from old pension systems. We also find that the average effect of the dividend remains unchanged for any constant annual rate of population growth, that contribu-tors who reach retirement age always get a higher r…

Adjustment mechanisms and intergenerational actuarial neutrality in pension reforms

2016

In the context of the reform of defined benefit pension systems under population ageing, we focus on the introduction of automatic adjustment mechanisms linked to life expectancy. Our goal is to establish a relationship between changes in the key parameters of the pension system and changes in life expectancy, applying the principle of intergenerational actuarial neutrality. For a defined benefit pension scheme, we first obtain the fundamental adjustment equation and then, for particular cases, we derive different designs of automatic adjustment mechanisms depending on the involved parameter. We include a numerical application only for illustrative purposes.

Influence of pillar 3 of pension system on retirement pensions level in Poland : will voluntary part of system enable decent life in old age?

2021

PURPOSE: The aim of this paper is the comparative analysis of the general saving ways included in pillar 3 of the pension system and showing their potential effectiveness from the perspective of the pension system participant. Will the resources allocated by the instruments of the voluntary pension system part significantly improve the level of the future pension? Will they allow a more decent life for an average Polish citizen in the period of the old age?

Non-Gaussian Distribution for Var Calculation

2003

Publisher Summary This chapter compares different approaches to computing Value-at-Risk (VaR) for heavy tailed return series. Each model has been submitted to a backtest analysis. The most representative asset returns of the Italian stock market and the exchange rates for the major currencies are used. The results obtained confirm that when the percentiles are below 5%, the hypothesis of normality of the conditional return distribution determines intervals of confidence whose forecast ability is low. In fact, it is observed that the return distributions are asymmetric and leptokurtic and the hypothesis of normality is usually rejected when subject to statistical test. Among the alternative …

Motivating Low-Achievers—Relative Performance Feedback in Primary Schools

2021

Abstract Relative performance feedback (RPF) has often been shown to improve effort and performance in the workplace and educational settings. Yet, many studies also document substantial negative effects of RPF, in particular for low-achievers. We study a novel type of RPF designed to overcome these negative effects of RPF on low-achievers by scoring individual performance improvements. With a sample of 400 children, we conduct a class-wise randomized-controlled trial using an e-learning software in regular teaching lessons in primary schools. We demonstrate that this type of RPF significantly increases motivation, effort, and performance in math for low-achieving children, without hurting …

From Rhetoric to Practice: The Case of Spanish Local Government Reforms

2013

This paper aims to explore what performance management tools are implemented in practice in Spanish local governments and whether they have led to an improvement in public management and accountability. We also analyse the usefulness of performance reporting, comparing it with that of accrual financial reporting. The results show that most of the entities that have introduced performance indicators do not use them for decision-making or accountability. After two decades of reforms in financial and management systems, financial directors still consider that budgetary reporting is the most useful, basically because the control of expenditure is still based on the budget.

Remarks on the economic interpretation of Hopf bifurcations

1999

Abstract The Hopf bifurcation theorem has become a frequently used tool in the study of nonlinear dynamical economic systems. In this paper, it is shown that phenomena like multiple limit cycles, hysteresis loops and catastrophic transitions may possibly accompany a Hopf bifurcation. The theoretical argument is illustrated in Foley's liquidity cost–business cycle model.

Patterns of poverty among elderly Americans: a Latent Class Markov Model

2017

ABSTRACTThis article studies poverty persistence and the role of social security programmes on poverty among elderly in the US. We use a Latent Markov model to disentangle unobserved heterogeneity and state dependence. Because of its dynamic nature, unobserved heterogeneity is modelled to vary over time. This allows to capture different latent states of poverty that change over time. Result indicates the existence of three unobserved types evolving over time according to their propensity to be poor. Moreover, a strong persistence in poverty especially for women, individuals living alone and ethnic minorities is found. Finally, the estimates indicate that giving social assistance tends to re…
