Determinants of Household Savings: A Cross-Country Analysis

This paper analyses determinants of household savings in a model based on an extension of the disequilibrium savings theory. These extensions follow from the life-cycle and permanent-income theories. Based on panel data for 14 countries spanning the period 2000–2018, fixed-effect least squares and two-stage least squares estimation procedures were used. In line with previous studies, there is strong and robust evidence for the hypotheses of disequilibrium savings theory, specifically, positive effects of unanticipated income changes, unanticipated inflation and the lagged savings rate. There is also robust evidence for the income uncertainty hypothesis that uncertainty has a positive effect on savings. The analysis presents some evidence that social security suppresses savings, but finds no significant effects on the interest rate or old-age dependency ratio. Unexpectedly, the participation rate of the elderly has a significant positive effect in some specifications. These findings contribute to the debate on whether and how governments can influence saving behavior.

     

Mokken scale analysis for polychotomous items: theory,a computer program and an empirical application

This paper contains three subjects. First, an extension of Mokken's nonparametric item response models from dichotomous items to items with two or more ordered answer categories is proposed. Second, a computer program to analyze multicategory item scores is presented. This program is called MSP. The analyses by means of MSP are based on the multicategory extension of Mokken's theory. Finally, an application of MSP to empirical multicategory test data is presented in order to illuminate its possibilities.     

HR in the small business enterprise: Assessing the impact of PEO utilization

Within small businesses, organizational leaders are themselves often responsible for the HR function, an area where they typically have limited training and experience. Not surprisingly, small business leaders have raised concerns about the quality of HR programs in their firms and the fact that HR consumes scarce managerial time. While professional employer organizations (PEOs) emerged in response to such concerns, much controversy exists as to whether and how small businesses benefit from PEO utilization. Using a survey of more than 740 small businesses, we examine the relationship between PEO utilization and two key small business outcomes: managerial time required by HR activities and satisfaction with HR outcomes. Our results indicate that firms not using a PEO reported significantly lower levels of satisfaction with HR outcomes than firms that used a PEO for a limited set of transactional services and firms that used a PEO for both transactional and strategic HR services. Among firms using a PEO, satisfaction with HR outcomes was significantly higher among firms that obtained a broader set of transactional and strategic HR services. Firms that used a PEO also reported that HR consumed significantly less managerial time relative to leaders in firms that made no use of a PEO. However, there was no significant difference in the time demanded by HR between firms that used a limited set of transactional services and those that used a broader range of transactional and strategic services. Implications for the role of PEOs and their use within small businesses are discussed. © 2005 Wiley Periodicals, Inc.     

Politicians’ motivation,political culture,and electoral competition

We study electoral competition among politicians who are heterogeneous both in competence and in how much they care about (what they perceive as) the public interest relative to the private rents from being in office. We show that politicians may have stronger incentives to behave opportunistically if other politicians are more likely to behave opportunistically. A political culture may therefore be self-reinforcing and multiple equilibria may arise. We also show that politicians’ incentives to behave opportunistically increase with politicians’ pay and with polarization of policy preferences. JEL Code D72 · D78     

Learning about fundamentals: The widening of the French ERM bands in 1993

Learning about Fundamentals: The Widening of the French ERM Bands in 1993. — The authors incorporate a Bayesian learning model into a fairly general model of exchange rate determination in discrete time. The model is applied to the period following the widening of the French-German ERM bands in August 1993, in which a systematic underprediction of the franc can be observed until February 1994. A (substantial) part of these forecast errors can be mimicked by a Bayesian learning process. Simulations with our model show that, after the widening of the bands, agents, contrary to their initial expectations, gradually learned that the true process driving monetary conditions in France had not changed notably.     

Co-optimization of enhanced oil recovery and carbon sequestration

In this paper, we present an economic analysis of CO₂-enhanced oil recovery (EOR). This technique entails injection of CO₂ into mature oil fields in a manner that reduces the oil's viscosity, thereby enhancing the rate of extraction. As part of this process, significant quantities of CO₂ remain sequestered in the reservoir. If CO₂ emissions are regulated, oil producers using EOR should therefore be able to earn revenues from sequestration as well as from oil production. We develop a theoretical framework that analyzes the dynamic co-optimization of oil extraction and CO₂ sequestration, through the producer's choice of the fraction of CO₂ in the injection stream at each moment. We find that the optimal fraction of CO₂ is likely to decline monotonically over time, and reach zero before the optimal termination time. Numerical simulations, based on an ongoing EOR project in Wyoming, confirm this result. We also find that cumulative sequestration is less responsive to the carbon tax than to the oil price. Only at very high taxes does a tradeoff between revenues from oil output and sequestration arise.     

Should Investors Avoid All Actively Managed Mutual Funds? A Study in Bayesian Performance Evaluation

This paper analyzes mutual-fund performance from an investor's perspective. We study the portfolio-choice problem for a mean-variance investor choosing among a risk-free asset, index funds, and actively managed mutual funds. To solve this problem, we employ a Bayesian method of performance evaluation; a key innovation in our approach is the development of a flexible set of prior beliefs about managerial skill. We then apply our methodology to a sample of 1,437 mutual funds. We find that some extremely skeptical prior beliefs nevertheless lead to economically significant allocations to active managers.     

On the Composition of Committees

This article is concerned with the role of committees in collectivedecision making processes in a world where agents must be motivatedto collect information. Committees improve the quality of decisionmaking by providing information and by coordinating the collectionof information. We address two types of questions. First, howdoes the composition of a committee affect final decisions?Second, what is the optimal composition of a committee fromthe decision maker's point of view? As to the latter question,we show that the cost of information collection plays an importantrole. If this cost is low, then the preferences of the committeemembers should be aligned to those of the decision maker. Memberswith similar preferences as the decision maker collect the properpieces of information. Moreover, manipulation of informationdoes not occur if the preferences of the decision maker andthe members are consonant. If the cost of searching is high,then the committee should be composed of members with polarizedpreferences. Outliers have a strong incentive to search forinformation.     

EQUIVALENCE SCALE SENSITIVITY OF POVERTY STATISTICS FOR THE MEMBER STATES OF THE EUROPEAN COMMUNITY

Using microdata from Household Budget Surveys of the Member States of the European Community, this paper examines the sensitivity of poverty statistics with respect to the choice of the equivalence scale. The results show that the ranking of the countries with respect to the overall poverty incidence is hardly affected when different equivalence scales are used. However, the composition of the poor population shows considerable changes when e.g. subjective equivalence scales are used instead of the OECD equivalence scale. The poverty incidence among specific household groups, such as single elderly and households with children, is particularly sensitive to the choice of the equivalence scale.
