Estimating liquidity premia in the Spanish government securities market

This paper investigates the presence of liquidity premia in the relative pricing of assets traded on the Spanish government securities market. First, a classification of bonds into four different categories based on their degree of liquidity is proposed. Second, liquidity premia are estimated introducing liquidity parameters in the estimation of the zero-coupon yield curve. Results suggest the existence of a liquidity premium for post-benchmark bonds (both strippable and non-strippable). The size of this premium is relatively small. In the case of pre-benchmark bonds, the lack of liquidity does not seem to be priced. It is also shown that these pricing discrepancies are robust to the impact of taxes on bonds.     

Dynamic capital structure and the contingent capital option

The financial crisis has emphasized the difficulties for financial companies to raise funds through conventional liabilities. In this environment, hybrid securities are becoming popular. In this paper we study the optimal capital structure of a company issuing a particular type of hybrid security: perpetual contingent capital, i.e., debt that converts into equity under some conditions. A two-period model with endogenous bankruptcy for a company with equity, straight debt and contingent capital is analyzed. We investigate the instrument under different conversion rules: automatic or optimally chosen by equity holders. We show that contingent capital reduces the coupon of straight debt and expected bankruptcy costs but can require a high spread. A trigger imposed by the regulatory authority in terms of par value of debt may induce a little use of contingent capital with an increase of bankruptcy costs.     

Pass-through in dollarized countries: should Ecuador abandon the US dollar?

In this article, we examine the convenience of dollarization for Ecuador today. As Ecuador is strongly integrated financially and commercially with the United States, the exchange rate pass-through should be zero. However, we sustain that rising rates of imports from trade partners other than the United States and subsequent real effective exchange rate depreciations are causing the pass-through to move away from zero. Here, in the framework of the Vector Error Correction Model, we analyse the impulse response function and variance decomposition of the inflation variable. We show that the developing economy of Ecuador is importing inflation from its main trading partners, most of them emerging countries with appreciated currencies. We argue that if Ecuador recovered both its monetary and exchange rate instruments, it would be able to fight against inflation. We believe such an analysis could be extended to other countries with pegged exchange rate regimes.     

Boards,Executive Excess Compensation,and Shared Power: Evidence from Nonprofit Firms

We investigate how executives, the board, and excess compensation jointly affect the performance of nonprofits. Since the common measure of nonprofit performance often includes salaries, we also use expenses that directly benefit the targeted population. Our results suggest that above average compensation for executives is associated with poor firm performance. However, the negative relation of CEO pay to performance occurs for firms with only one executive, the CEO. We conclude that a powerful CEO with autonomy can harm firm performance, but other executives can mitigate these agency problems. The board also appears to monitor direct community benefits more than indirect benefits.     

Patterns of consumer response to retail price differentials

Decomposing price elasticity suggests that the major impact of promotions is on brand switching rather than increased consumption. Consumers may also buy smaller quantities of more expensive brands when compared to cheaper ones (inter-brand elasticity). Using panel data for the purchases of 80 consumers buying nine product categories over a 16-week period, we verified that inter-brand elasticities occur, and report the relative importance of intra- and inter-brand elasticities in determining quantity price elasticity per shopping occasion for the product category. Brands were classified by informational (socially mediated) and utilitarian (product-mediated) benefits. Intra-brand elasticity was higher than utilitarian inter-brand elasticity, which was higher than informational inter-brand elasticity.     

Housing and cost of living: Application to the Spanish regions

Spain is a home-owner economy, and housing is a key good for determining the cost of living. However, its treatment in indices such as the Spanish Consumer Price Index (CPI) makes it impossible to measure the real impact of housing on the cost of living. This issue is especially relevant at the regional level, where the differences in the housing markets are very substantial. This paper demonstrates the importance of taking account of owner occupied housing in a measure of the cost of living for Spain.     

Qualitative/quantitative integration in the inductive observational study of interactive behaviour: impact of recording and coding among predominating perspectives

A strong dichotomy has traditionally been established between qualitative and quantitative approaches. This question has been the subject of intense debate from a methodological point of view, and in recent years there are clear signs that the conflict is being overcome; nevertheless, we are still some way from a genuine position of complementarity and integration, and the issue remains to be considered in the process of theorization along the tortuous path that leads from the particular to the general. The proposal in this article takes a further step forward as regards this question, this time with respect to the study of interactive behaviour. The key is once again the consideration of a “complete unit” of analysis, but the logic of the observational methodology process enables the perspectives to be sequenced: the study begins with a predominantly qualitative approach before subjecting the data to a given type of recording (through the important support of field formats) and coding (preferably computerized), thus producing a matrix of formally interchangeable data; finally, the criterion is reversed and the study continues under a predominantly quantitative perspective.     

School completion in urban Latin America: the voices of young people from an informal settlement

Despite progress in improving secondary school completion in Latin America, a high proportion of young people from urban marginalised neighbourhoods continue to drop out. On the basis of in-depth interviews with young people in an informal settlement of the City of Buenos Aires, the paper aims to broaden the understanding of the processes that lead to school dropout in these neighbourhoods. It does so by examining what young people value being and doing, and how they interpret the value of secondary school in their own lives and contexts. The results point to the critical importance of the family in young peoples’ processes of reasoning and decision-making, the complex interaction between capabilities, and the benefits of schools that provide social and emotional support to students and families. The paper argues that listening to the voices of young people can give significant insights for the design of policies to close the gap in education outcomes in segregated urban contexts.     

Measuring price discovery between nearby and deferred contracts in storable and nonstorable commodity futures markets

Using price discovery measures, including Putniņš’ (2013) information leadership share and intraday data, we quantify the proportional contribution of nearby and deferred contracts in price discovery in the corn and live cattle futures markets. On average, nearby contracts reflect information more quickly than deferred contracts in the corn market, but have a relatively less dominant role in the live cattle market. In both markets, the nearby contract loses dominance when its relative volume share dips below 50%, which typically occurs when the nearby is close to maturity. Regression results indicate that the share of price discovery is mainly related to trading volume and time to expiration in both markets. In the corn market, price discovery share between nearby and deferred contracts is also related to inverse carrying charges, crop year differences, USDA announcements, market crashes, and commodity index position rolls. Differences between corn and live cattle markets are consistent with differences in the contracts’ liquidity and commodity storability.     

Rational drug use in hospital settings – areas that can be changed

Abstract

Irrational use of drugs occurs at all levels of healthcare. This phenomenon can also be observed in hospitals. Irrational use of a drug contributes to a decrease in the patient's quality of treatment and often causes negative health consequences. For this reason, it is essential to consider methods that can be introduced in hospitals to increase the safety and effectiveness of the drugs used. The article presents selected methods of rationalization of drug management that can be used in hospitals.
