The Gendered Nature of Poverty in the EU: Individualized versus Collective Poverty Measures

Due to the adoption of the household as a unit of analysis, researchers have failed to identify accurate measures of women's income poverty. This study proposes an individualized measure of European poverty to highlight gender differences in the economic crisis. Employing data from the European Union Statistics on Income and Living Conditions (EU-SILC) for the period 2007–12, it compares the household-based at-risk-of-poverty rate (ARPR) and the individualized financial dependency rate (FDR). The study shows that the gender gap in poverty in Europe is considerably higher when computed through FDR. Indeed, since the ARPR constitutes a proxy of the household's average conditions, it levels down gender inequalities within the household and also variations in individuals’ incomes over time. Only more detailed data collection on intrahousehold resource sharing will possibly allow the development of more precise and realistic indicators of women's and men's risks of poverty and financial dependency.     

Fiscal rule compliance,poverty and social exclusion in the Eurozone

This paper develops a simple model of the effects of fiscal adjustments on poverty. Our theory suggests that in richer countries the effects of fiscal adjustment are stronger the more complex is the poverty measure. By examining a panel of 16 EU countries in the period 2005–2015, the paper finds that structural public balance adjustments may harm the welfare of poorer individuals. The empirical estimation hinges on a comprehensive index of poverty and social exclusion, the AROPE index. The results suggest that rigid fiscal rules require specific alternative policies to sustain the welfare of poorer individuals during downturns.     

Income concentration and market demand

We analyze the effects of income concentration and income dispersionon market demand and its elasticity. We show that, followingan increase in income concentration towards the middle (measuredby variations in mean preserving spread), the increase in demandfaced by firms which serve at the margin middle income consumers,is associated with an increase in price elasticity—accordingly,the positive effects of the size of the market becoming widerare amplified by a higher degree of competition. Our resultshold for a large number of possible income distributions.     

Stock market overreactions to bad news in good times: a rational expectations equilibrium model

This article presents a dynamic, rational expectations equilibriummodel of asset prices where the drift of fundamentals (dividends)shifts between two unobservable states at random times. I showthat in equilibrium, investors' willingness to hedge againstchanges in their own 'uncertainty' on the true state makes stockprices overreact to bad news in good times and underreact togood news in bad times. I then show that this model is betterable than conventional models with no regime shifts to explainfeatures of stock returns, including volatility clustering,'leverage effects,' excess volatility, and time-varying expectedreturns.     

SPATIAL DISCRIMINATION,PRODUCT SUBSTITUTABILITY AND WELFARE

The paper examines a quantity–location duopoly game in a spatial discrimination model in which the delivered goods are assumed to be imperfect substitutes or complements. By extending the range of the unit transportation cost analysed in the existing literature, it is shown that a dispersed equilibrium arises in which the choice of the optimal locations is affected by the degree of product substitutability. The interaction between the latter and the size of the transportation cost is also discussed in order to verify its welfare implications. In particular, it is shown that in this spatial framework imperfect substitutability may increase welfare.     

Optimal manipulation rules in a mixed oligopoly

We study the optimal manipulation rules of a public firm’s objective function in a mixed oligopoly with imperfect product substitutability. We start with a baseline duopoly model and compare the solutions under quantity and price competition, and the way they are affected by product substitutability. This allows us to show that partial privatization, strategic delegation and other specific government’s commitments on the objective function of the public management can be looked at as special cases of these optimal rules, and to evaluate the viability of these policies under the two modes of competition. In this framework, we also discuss the equivalence between manipulation of the objective function and Stackelberg leadership. Since optimal manipulation rules change as new dimensions are added, we also derive the optimal rules under oligopoly, quadratic costs, and competition of international firms. This fairly general unified framework allows to discuss the impact of these factors on the government’s implementation policies of the optimal manipulation rules.     

Exploring the role of charitable ethnocentrism and donation motives in international giving: Empirical evidence from Germany

The purpose of this study is to contribute to a better understanding of the drivers of international giving intention by examining the joint effect of ethnocentrism and donation motives. More specifically, this study analyzes the direct effect of charitable ethnocentrism on the intention to give to international causes. Additionally, the study investigates the moderating effect of charitable ethnocentrism on the relationships between donation motives and the intention to donate to international causes. This study's findings indicate that ethnocentric donors are less willing to donate to international causes. Moreover, the study results show that the effects of egoistic and tax-saving donation motives vary across different levels of charitable ethnocentrism: charitable ethnocentrism enhances the effect of the egoism motive on international donation intention, whereas the effect of the tax-saving motive on international giving intention is mitigated. Based on the empirical findings, this study discusses implications for theory and practice along with study limitations and avenues for future research.     

National Health Service Boards of Directors and Governance Models

Abstract

This article reports the findings of a year-long research project focused on the activity of boards of directors of twenty-two trusts from the British National Health Service (NHS). The evidence gathered through the use of semi-structured interviews, focus groups, workshops, feedback questionnaires and document analysis indicates that the behavioural dynamics of boards, affected by the dominance of the expert model, act as antecedents of their statutory functions and the implementation of different governance models. Only a portion of the boards involved has effectively incorporated in its modus operandi post-New Public Management (post-NPM) principles of governance.     

Rational panics and stock market crashes

This paper offers an explanation for stock market crashes which focuses on the role of rational but uninformed traders. We show that uninformed traders can precipitate a price crash because as prices decline, they surmise that informed traders received negative information, which leads them to reduce their demand for assets and drive the price of stocks even lower. The model yields several implications, such as that crashes can occur even when the fundamentals are strong, and that the magnitude of the crash depends on the fraction of uninformed investors and the amount of unsophisticated passive investing present in the market.
