Conditional conservatism and cost of capital

We empirically test the association between conditional conservatism and cost of equity capital. Conditional conservatism imposes stronger verification requirements for the recognition of economic gains than economic losses, resulting in earnings that reflect losses faster than gains. This asymmetric reporting of gains and losses is predicted to lower firm cost of equity capital by increasing bad news reporting precision, thereby reducing information uncertainty (Guay and Verrecchia 2007) and the volatility of future stock prices (Suijs 2008). Using standard asset-pricing tests, we find a significant negative relation between conditional conservatism and excess average stock returns over the period 1975–2003. This evidence is corroborated by further tests on the association between conditional conservatism and measures of implied cost of capital derived from analysts’ forecasts.     

Earnings forecasts: the case for combining analysts’ estimates with a cross-sectional model

Portfolio selection with commodities under conditional copulas and skew preferences

This article investigates the portfolio selection problem of an investor with three-moment preferences taking positions in commodity futures. To model the asset returns, we propose a conditional asymmetric t copula with skewed and fat-tailed marginal distributions, such that we can capture the impact on optimal portfolios of time-varying moments, state-dependent correlations, and tail and asymmetric dependence. In the empirical application with oil, gold and equity data from 1990 to 2010, the conditional t copulas portfolios achieve better performance than those based on more conventional strategies. The specification of higher moments in the marginal distributions and the type of tail dependence in the copula has significant implications for the out-of-sample portfolio performance.     

The PPP hypothesis and structural breaks: the case of Mexico

We test the purchasing power parity hypothesis for the Mexican peso/US dollar real exchange rate using monthly data for 1969–2010. Results suggest that the real exchange rate reverts to a changing mean. These mean shifts can be explained by liberalization policies implemented during the 1980s and 1990s that reduced trade barriers in the Mexican economy. Such policies modified the tradable/non-tradable goods composition of the price index producing mean shifts in the real exchange rate associated with PPP.     

The Just Price: Three Insights from the Salamanca School

In the sixteenth and seventeenth centuries, members of the Salamanca School engaged in a sustained and sophisticated discussion of the issue of just prices. This article uses their contribution as a point of departure for a consideration of justice in pricing which will be relevant to current-day circumstances. The key theses of members of this school were that fairness of exchanges should be assessed objectively, that the fair price of an article is one equal to its ‘value’, and that the best indicator of that value is the price that article commonly fetches in an open market. This article tries to bring to light the attractiveness of those views in order to guide current practice by contrasting them with alternative views, showing their connection with intuitively attractive basic standards, and linking them to commonly shared intuitions.     

Demand Revelation,Hypothetical Bias,and Threshold Public Goods Provision

We examine the issues of hypothetical bias, demand revelation, and gender differences in a threshold public goods experiment with heterogeneous induced-values. First, we find no evidence of hypothetical bias in our threshold provision public goods experiments, despite the fact this is an open-ended type mechanism. Our results support recent experimental findings that use induced-values to investigate hypothetical bias. Second, we investigate the demand revealing performance of real and hypothetical payments and find no evidence that real payment performs better than hypothetical payment in our experiments. Third, we examine whether payments, real and hypothetical, are positively related to induced-values. Our results suggest there is statistical evidence that payments are positively related to true values. Finally, we examine the effect of gender on real and hypothetical payments in our experiment. The results show that gender matters for contributions through both real and hypothetical payments, after controlling for true values as well as socio-economic variables. Results also indicate that females are more likely to truthfully reveal their value than males through hypothetical payments, but gender is not significant for truthfully revealing their value through real payments.     

Duality between direct and indirect preferences

Summary This paper develops a duality theory for preference orders, and highlights important differences with respect to the cardinal utility approach. Our main result is a symmetric duality theorem, under the minimal hypotheses, between direct and indirect preferences. In contrast to the cardinal theory, we also find that these conditions do not completely characterize the class of indirect preference orders.We are grateful to an editor for helpful remarks.

Determinants of work organization in the modern firm: change and continuity in the Spanish labour relations

The host of statistical data on labour organization from the 2004 Encuesta de Calidad de Vida en el Trabajo (2005) will be used as a basis for using factorial analysis to identify the factors that determine how ‘modern’ companies organize their work according to business management literature. Workers' identification with their company seems to be the essence of a good part of business managers' objectives. The results of the research point to a continuity in a worker profile that largely corresponds to the Fordist model, with a few significant changes: the domain of some non-conflictive industrial relations which is settled on the value that is given to the good relationships with mates and managers and the flexible work-class positive assessment that allows to harmonize other life aspects.     

The associations between early life circumstances and later life health and employment in Europe

We use data from the Survey of Health, Aging, and Retirement in Europe to estimate for thirteen European countries the associations of early life circumstances—measured by childhood health and socioeconomic status (SES)—with educational attainment, and later life health and employment (at ages 50–64). In all countries and for men and women, favorable early life circumstances, and in particular a higher childhood SES, are associated with a higher level of education. In most countries and in particular for women, favorable early life circumstances are associated with better later life health, also when education is controlled for. The significant associations of favorable early life circumstances with a higher incidence of later life employment are mostly transmitted through education and later life health.
