Why is timing perverse?

The existence of negative market timing, even for passive portfolios, poses a relevant puzzle when assessing portfolio management. In this paper, we develop a simple theoretical model so as to explain why such perverse market timing might occur and why those stocks with the lowest beta in upward markets exhibit pronounced negative timing. Our explanation is based on the existence of higher correlations of stocks in down markets than in up markets. We find that changes in beta, which drives timing, has four components; however, just two of these, mean covariance shift and covariances dispersion map, serve to explain the asymmetric behavior across stocks. We find that a high percentage of the negative market timing ability identified for mutual funds in the literature could be explained by this bias.     

Delaying retirement in Spain

We study the reform of the Spanish public pension system in a multiperiod, general equilibrium, overlapping generations model economy populated by heterogeneous households. Our households differ in their place of birth, in their age, in their education and, endogenously, in their employment status, in their wealth, and in their pension entitlements. They receive a stochastic endowment of efficiency labor units each period. And they face a disability risk and a survival risk. They understand the link between the payroll taxes that they pay and the public pensions that they receive. And they decide how much to consume and to work, and when to retire from the labor force. We calibrate this economy to Spanish data, and we use it to study the consequences of delaying three years the statutory retirement ages in 2010. We find this reform is sufficient to solve the sustainability problems that plague the current Spanish public pension system. Our model economy predicts that under the current rules, the pension system fund will run out in 2028 and in the reformed economy it will last until 2050. We also find that it is moderately expansionary, and that it improves social welfare from the year 2015 onwards. We conclude that policymakers should seriously consider delaying the statutory retirement ages in Spain sometime in the near future.     

Kriging methodology for regional economic analysis: Estimating the housing price in Albacete

Because of the socioeconomic importance of the housing subsector in the local, regional, and national economy and its implications for housing policy, this paper attempts to analyze the spatial behavior of the free housing price in the city of Albacete. To achieve this aim, the authors have used the models and estimators imported from geology called kriging. To do this, it is necessary to know the spatial dependence structure of the process, which is shown in the variogram.     

DOES MOTHER'S EDUCATION MATTER IN CHILD'S HEALTH? EVIDENCE FROM SOUTH AFRICA1

Using the 1993 South Africa Integrated Household Survey, this paper studies the effect that mother's education through the knowledge channel has on children's health using height for age Z‐scores as health measure. Under a two‐stage least square methodology we find that an increase in 4 years on mother's education (approximately 1 standard deviation) will lead to an increase of 0.6 standard deviations on her child's height for age Z‐score. We also find, as the medical literature suggests, support for the hypothesis that mother's education is more important for children older than 24 months of age.     

Who buys newspapers in Spain? An analysis of the determinants of the probability to buy newspapers and of the amount spent

In this paper, we examine the determinants of household consumption of newspapers and the amount spent on their purchase by considering several explanatory variables related to household characteristics and the main household wage earner. Results show that the variables have quite similar effects on both the relative probability of buying newspapers and the amount spent. The key variables are the age and occupational status of the main wage earner, the number of household members, income and having to pay for the house, as well as a number of geographical variables. However, certain differences are also observed. The most important is the education of the main wage earner: while its effect on buying newspapers is very small (only those who did not complete primary education are less likely to buy), its effect on the amount spent increases with the level of education. As other studies of cultural goods and services consumption have suggested, education and occupational status are more relevant determinants than income.     

Innovation, progress, entrepreneurship and cultural aspects

In the case of economic progress, some of the literature has considered economic growth and economic progress to be the same thing. However, there is a relevant difference between the two concepts. As Holcombe states, economic growth considers the quantity of products and economic progress the quality of products. Innovation has been considered as a key factor to promote economic progress. A culture would have a direct and an indirect effect on innovation through entrepreneurship. The goal of this paper is to analyze the relationship between culture and innovation. To carry out this study, an empirical estimation has been developed for the case of 11 countries.     

Entrepreneurial Structure Qualitative Analysis: The Case of Seville (Spain)

In the field of territorial economic growth, it is possible to identify important characteristics in the entrepreneurial structure, such as the structure of the size of firms, main activity sectors, or the degree of innovation. However, other lesser known characteristics are important also, such as functional dependency, which considers the relationship between small and medium enterprises (SMEs), and suppliers and clients belonging to any territorial field or productive dependency, which considers the level of concentration in terms of buying and selling in connection with the main suppliers and clients, respectively. In order to empirically contrast the importance of these entrepreneurial characteristics and try to relate them with territorial economic growth, a sample of 400 enterprises in the province of Seville (Spain) is used.      

‘Adopt a Hypothetical Pup’: A Count Data Approach to the Valuation of Wildlife

The willingness to pay (WTP) for a coyote conservation program is estimated using a novel payment-vehicle, based on how many ‚problem’ coyotes respondents would be willing to sponsor for a year. This hypothetical scenario mimics an increasingly popular type of actual market. Data from a phone survey conducted in Prince Edward Island are analyzed using count data models that consider different processes explaining zero responses and the level of positive responses. This is particularly important in the case of coyotes, often regarded as an economic bad. Estimates of WTP per coyote per year around $18–$22 and annual WTP per contributor of about $46–$57 are obtained.      

INTERORGANIZATIONAL TIME‐BASED POSTPONEMENT IN THE SUPPLY CHAIN

This paper presents the results of empirical research on the use of time‐based postponement in a supply chain context using data collected from two manufacturers, a distributor, and a retailer. The analysis shows that implementing postponement at the firm level can result in the supply chain carrying more inventory. In order to achieve its full potential, postponement needs to be implemented across organizations in the supply chain.
