Defined Benefit or Defined Contribution? A Study of Pension Choices

We solve an empirically parameterized life‐cycle model of consumption and pension choices to show how expected earnings growth and risk affect the benefits of final‐salary defined benefit (DB) pension plans, relative to pension plans that are defined contribution (DC) in nature. We use micro data on the pension choices of individuals to provide evidence consistent with the model predictions: (1) individuals who expect a higher growth rate of earnings are more likely to choose DB final‐salary schemes, and (2) individuals who face a higher variance of persistent income shocks are less likely to choose DB final‐salary schemes. We control for cohort and age fixed effects in the empirical analysis.     

Instability in cointegration regressions: a brief review with an application to money demand in Portugal

This study addresses some modelling questions related to the possibility of structural change in models with nonstationary variables. Focusing on cointegration issues, some methodological aspects are discussed, attempting to integrate coherently the several steps of the modelling strategy. These range from unit root to cointegration testing and to testing for instability in the cointegration vector. An empirical example with Portuguese data tries to illustrate the usefulness of this approach, where a simple money demand function is estimated using an error-correction model (ECM). If a break is explicitly allowed in the cointegration vector the forecasting performance of the ECM improves.     

From Self-Interest Motives to Justice Motives: The Challenges of Some Experimental Results

A bstract .   This article begins by presenting experimental evidence that remains unexplained by standard and utility-extended economic models: experimental subjects tend to honor their promises even on occasions when an assessment of consequences asks them to defect; subjects voluntarily contribute to collective goods, and this contribution is highly conditional on others contributing as well; subjects evaluate and value the intentions behind actions as well as the consequences of actions. Arguments are sought for in moral philosophy that would more plainly explain the collected experimental evidence and that would help economists revise their explanatory frames. The hypothesis advanced is that the observed behavior may be interpreted as resulting from the moral strength of indignation and justice norms.     

Assessing economic complexity as interindustry connectedness in nine OECD countries

Economic complexity can be defined as the level of interdependence between the component parts of an economy. In input–output systems interindustry connectedness is a crucial feature of analysis, and there are many different methods of measuring it. Most of the measures however, have important drawbacks to be used as a good indicator of economic complexity, because they were not explicitly made with this purpose in mind. In this paper, we present, discuss and compare empirically different indexes of economic complexity as intersectoral connectedness, using the inter-industry tables of nine OECD countries. According to most of the measures of connectedness large economies (USA, Japan) tend to be more complex than small economies (for example, Denmark). But if another type of measures is considered, the opposite conclusion is drawn, signalling a hidden characteristic of interdependence that so far has not been detected by conventional measures. This result should qualify the widespread idea that more interconnected productive structures propagate more intensely exogenous shocks and/or economic policy measures.     

The Way into Bankruptcy: Market Anomie and Sacrifice Among Portuguese Consumers

Portugal ranks among the EU27 countries with higher levels of consumer indebtedness. Contrary to the trend observed in countries with similar indebtedness rates, Portugal has one of the lowest rates of consumer default. Previous studies (e.g., Frade et al. 2006) have identified three strategies that have contributed to keep levels of credit default low: reliance on savings, financial support from relatives and friends, and cuts in household expenses. These strategies have been widely used for the last decade and have been strained since the very beginning of the global financial crisis in 2007. We argue that these three strategies are near to collapse and consequently the levels of consumer default will rise steeply in the next years. The savings rate in Portugal has been declining over time, and the social networks are limited in their action due to the current crisis that affects everyone. In this article, we advance the hypothesis that sacrificing living standards is rooted on collective beliefs about the current economic crisis in Portugal and trust in political and market agents in line with the Theory of Market Anomie (Karstedt and Farrall 2006). The conclusions are based on macroeconomic statistics and on the results of a Web survey of 1244 Portuguese households, which focuses on attitudes towards the financial crisis, trust in political and economic institutions, and strategies to cope with the crisis. The results show that trust in financial companies (banks and insurance companies) and in the European Parliament promotes a sense of empowerment to contribute to the country economic restoration. This attitude induces citizens to avoid default by sacrificing living standards. But in the current austerity context, with low levels of trust in political institutions and detachment of the economy, consumers will be less prone to sacrifice. In this scenario, credit default and insolvency is expected to rise especially in those households most exposed to unemployment and to cuts in social benefits. This reality puts a huge and growing pressure on bankruptcy procedure, civil courts, and economic and social policies. Some adjustments should be made to the Portuguese Bankruptcy Code by facilitating and simplifying the bankruptcy regime in order to accommodate the increase in insolvency cases. But the improvement of the insolvency procedure will not resolve the situation of financial distress if the structural causes persist, such as unemployment and deterioration of salaries, and cuts in social benefits. A reform of the Bankruptcy Code facilitating and simplifying the bankruptcy regime should be coupled with measures that boost the economy and stimulate the labour market. Otherwise, Portuguese households will not have the resources necessary to benefit from the bankruptcy process and regain the control over their financial lives.     

New Jersey's health care system reforms

As New Jersey grappled with the huge burden of uncompensated hospital care, a diverse group of organizations banded together to develop a unique private sector response to the immediate crisis and a long-term strategy for comprehensive reform of the state's health care system.     

Deterministic seasonality in Dickey–Fuller tests: should we care?

This paper investigates the properties of Dickey–Fuller tests for seasonally unadjusted quarterly data when deterministic seasonality is present but it is neglected in the test regression. While for the random walk case the answer is straightforward, an extensive Monte Carlo study has to be performed for more realistic processes and testing strategies. The most important conclusion is that the common perception that deterministic seasonality has nothing to do with testing for the long-run properties of the data is incorrect. Further numerical evidence on the shortcomings of the general-to-specific t-sig lag selection method is also presented.

Intuition and rationality in intrapreneurship and innovation outputs: The case of health professionals in primary health care

The aim of this article is to explore the role of cognitive styles and intrapreneurship in health professionals’ innovation outputs, as well the mediated effect of intrapreneurship between cognitive styles and innovation output. This study used the survey method of data collection, through a self-administered questionnaire. Partial least square structural equation modelling method was used to analyse the result of the sample of 209 professionals of primary health care providers in Northern Portugal. Our findings reveal that cognitive style plays a significant role in intrapreneurship and innovation outputs, which are mediated by intrapreneurship. In particular, health care professionals with the rational cognitive style are likely to be more of a intrapreneur and innovative as compared to those with a intuitive cognitive style. Promoting intrapreneurship is crucial for successful innovation outputs. This study reveals that an understanding of the cognitive style of the health care professionals can help managers allocate appropriate individuals to different healthcare tasks. Our primary contribution to theory has been to highlight the importance of cognitive styles in intrapreneurship and innovation within the context of primary health care organizations.
