Market illiquidity and bounds on European option prices

The paper analyses the impact of illiquidity of a stock paying no dividends on the pricing of European options written on that stock. In particular, it is shown how illiquidity generates price bounds on an option on this stock, even in the absence of other imperfections, such as transaction costs and trading constraints, or the assumption of stochastic volatility. Moreover, price bounds are shown to be asymmetric with respect to the option price under perfect liquidity. This fact explains, under some conditions, the appearance of a smile effect when the implied volatility is estimated from the mid-quote.     

The Intellectual Structure Of Research Into PPPs

Abstract

Public–private partnerships (or PPPs) encompass a broad spectrum of public sector infrastructure and service initiatives. Recently, some scholars have undertaken literature review studies of the various definitions of the concept of PPPs and its research traditions, identifying several distinct PPP research approaches. This article aims to: (1) enhance the findings of these literature reviews; (2) identify the cited works and authors (intellectual structure) in the published research on PPPs; (3) define the subfields that constitute the intellectual structure of PPP research fields. The methodology is based on the bibliometric techniques of citation and author co-citation analysis applied to published research on PPPs included in the Social Science Citation Index.     

Humanistic leadership: Lessons from Latin America

We review the psychological, sociological and historical explanations underlying leadership styles in Latin America. A fundamentally paternalistic style relies on social bonds based on reciprocity and stresses workers’ expectations. Transformations in leadership styles in Latin America require consideration of alternative theoretical approaches such as stakeholder management and cultural hybridism, beyond cross-cultural frameworks. Viewing employees as key stakeholders implies a legitimate concern for workers beyond the employment relationship. From a hybridism perspective, diversity is a critical concept that applies to organizational ownership arrangements, management practices, cultural backgrounds, and socio economic contextual changes surrounding leadership styles.     

The future of employment supply and demand in social Europe

The assessment of employment prospects during the period up to 2020 needs to take into account the effects of the 2008/2009 downturn. We propose two scenarios that capture distinctive trajectories in order to elucidate some of the potential strategic demands for future employment policy. We forecast the average level of education of the working-age population will increase significantly during this decade and therefore the mismatch between the needs and supply of skills is likely to be significantly reduced. Furthermore, the inherent mobility of the working population will increase together with higher levels of education.     

Reverse convertible bonds analyzed

We study the pricing of reverse convertible (RC) bonds. These are bonds that carry high coupon payments. In exchange, the issuer has an option at the maturity date to either redeem the bonds in cash or to deliver a pre‐specified number of shares. We find that Dutch plain vanilla and knock‐in RC bonds are, on average, overpriced by almost 6%. This overpricing is confirmed in a model‐free analysis with respect to option‐ and bond‐pricing models. We find that rational factors explain 23% of the documented overpricing. In addition, we find that the combination of financial marketing, framing, and the representativeness bias further increases our ability to explain the documented overpricing to more than 35%. © 2009 Wiley Periodicals, Inc.

Who’s Displaced First? The Role of Race in Layoff Decisions

We test empirically the proposition that race significantly affects an employee's layoff chances. Using data from a financial firm (N = 8918), we find that whites are less likely to be laid off than nonwhites and that, among nonwhites, Asians are less likely to be laid off than blacks or Hispanics. These findings are statistically significant after controlling for structural factors (business unit, occupation, and job level) and individual characteristics (tenure and performance rating). A similar pattern of racial differences exists in other employment practices more actively monitored by the firm, including promotions, pay raises, and performance ratings. Yet these differences are smaller than those in layoffs and are significant for blacks only, not for Hispanics. Our findings suggest that monitoring personnel decisions can reduce racial inequality. Furthermore, our findings highlight that racial differences in employment outcomes vary among minority groups.     

Income Inequality and Health: Do the Equivalence Scales Matter?

The aim of this paper is to explore the relationship between income inequality and health in the European Union countries using new data from the European Community Household Panel (ECHP). The heterogeneity of the households has been approached using different equivalence scales. A variety of different model specifications were tried using different dependent variables such as life expectancy at birth and child mortality. The results give support to the influence of income inequality on health indicators using aggregate data and panel techniques, and show the sensitivity of the Gini index to the equivalence scale considered.     

Trade raises income: a precise and robust result

Does international trade promote income? Earlier studies could not provide conclusive evidence. This paper re-examines this question. Following previous work, we treat trade as endogenous and use geography to instrument for trade. We use a richer data set that allows us to estimate the impact of trade on income with much greater precision. We also show that geographical controls must enter the income equation to avoid bias. We find that countries that trade more reach higher levels of income. This result is remarkably robust to a wide array of geographical and institutional controls.     

A look into the factor model black box: Publication lags and the role of hard and soft data in forecasting GDP

We derive forecast weights and uncertainty measures for assessing the roles of individual series in a dynamic factor model (DFM) for forecasting the euro area GDP from monthly indicators. The use of the Kalman smoother allows us to deal with publication lags when calculating the above measures. We find that surveys and financial data contain important information for the GDP forecasts beyond the monthly real activity measures. However, this is discovered only if their more timely publication is taken into account properly. Differences in publication lags play a very important role and should be considered in forecast evaluation.     

Risky behaviours of males and females in a Spanish suburban community

Health is determined by an accumulative process, so a perspective on life cycle is crucial in any health prevention programme. As a consequence of this accumulative dimension, lifestyles are a key determinant of the state of health of older people. The main contribution of this paper is to explain gender differences in lifestyle and the implications of lifestyle in men's and women's states of health. We have implemented our empirical analysis into Spanish society through the use of a self‐elaborated survey. From this survey, we have drawn a subsample of 938 people older than 14 years old who live in the Spanish neighbourhood of Casablanca, Zaragoza (452 men and 486 women). We conclude that men tend to consume more substances that may negatively affect their state of health (alcoholic beverages, tobacco products and coffee), and they are also less careful in keeping an adequate weight and dental hygiene. On the other hand, women tend to be more sedentary. These results are decisive for policy makers that strive to improve the citizens’ state of health, because it is not only important to improve the quality and extension of healthy goods and services, but also to promote healthy lifestyles.
