AN EMPIRICAL ANALYSIS OF CHILD CARE DEMAND IN SWITZERLAND

ABSTRACT ** :  This paper analyzes the demand of Swiss families for child care facilities. A choice experiment is used to study the effects of the facilities' characteristics as well as socio-economic factors on the selected child care mode. The experimental data are analyzed using a discrete choice model with multinomial logit specification. The results suggest that the demand for extra-familial day care could be considerably higher than that observed from the actual choices constrained by insufficient provision of affordable day care. The price, access, and the quality of service as well as parents' income and education have important impacts on the choice of the mode of care.     

Exclusive Dealing: Investment Promotion May Facilitate Inefficient Foreclosure

This paper studies a model whereby exclusive dealing (ED) can both promote investment and foreclose a more efficient supplier. Since ED promotes the incumbent seller's investment, the seller and the buyer realize a greater surplus from bilateral trade under exclusivity. Hence, the parties involved may sign an ED contract that excludes a more efficient entrant in circumstances where ED would not arise absent investment. The paper therefore invites a more cautious attitude towards accepting possible investment promotion arguments as a defense for ED.     

Acquisition of Information and Share Prices: An Empirical Investigation of Cognitive Dissonance

Abstract. This paper deals with the determinants of agents' acquisition of information. Our econometric evidence shows that the general index of Italian share‐prices and the series of Italy's financial newspaper sales are cointegrated, and the former series Granger‐causes the latter, thereby giving support to the cognitive dissonance hypothesis: (non‐professional) agents tend to buy the newspaper when share prices are high and not to buy it when share prices are low. Instead, we do not find support for the hypothesis that the agents acquire information in order to trade in the stock market: we find no relationship between quantities exchanged in the market and newspaper sales, nor between stock market volatility and newspaper sales.     

Time and Risk Diversification in Real Estate Investments: Assessing the Ex Post Economic Value

Welfare gains to long-horizon investors may derive from time diversification that exploits nonzero intertemporal return correlations associated with predictable returns. Real estate may thus become more desirable if its returns are negatively serially correlated. While it could be important for long-horizon investors, time diversification has been mostly investigated in asset menus without real estate and focusing on in-sample experiments. This article evaluates, ex post, the out-of-sample gains from diversification when equity real estate investment trusts (REITs) belong to the investment opportunity set. We find that diversification into REITs increases both the Sharpe ratio and the certainty equivalent of wealth for all investment horizons and for both classical and Bayesian (who account for parameter uncertainty) investors. The increases in Sharpe ratios are often statistically significant. However, the out-of-sample average Sharpe ratio and realized expected utility of long-horizon portfolios are frequently lower than that of a one-period portfolio, which casts doubt on the value of time diversification.     

University-Business Cooperation in Education： Real and Perceived Performances

The purpose of this paper is to describe and demonstrate the validity of a methodology to distinguish, in the performances of high education institutions （HEIs）, real from perceived performances. The extension of accountability to the evaluation of educational programs involves significant topics concerning the gap between perceived and real performances. It means that, since many actors such as teachers, students, and external stakeholders are involved in the process, the research on methodologies to distinguish subjective from objective parameters is still on the floor. Debate about performance evaluation in this collaboration is still in progress particularly as it concerns the proposal of several parameters and indexes to quantify the topic and reduce the subjectivism in the assessment and the gap between real and perceived performances. After describing and discussing an evaluation model based on three interdependent typologies of indexes, this will be tested in two Tempus projects having the purpose of activating Ph.D. and masters courses. The results encourage deepening researches in this direction and disseminating this methodology and extending and enriching the validation process.     

Locus of control and individual learning: the moderating role of interactional justice

Organizations are increasingly investing in training programs for building managerial skills, with a special focus on employees considered ‘talents’ who must be prepared to cover strategic roles within the organization. One of the main goals of such programs is to develop participants' learning in order to tap their potential in a short time frame, ultimately to gain competitive advantage. However, participant learning is a complex process that can be hindered by different elements related to the characteristics of individuals and the context in which they act. In our research, we conducted a field study to analyze how the individual trait of locus of control (LOC) may negatively affect learning. Moreover, our study indicates that the contextual characteristic of interactional justice mitigates the negative effect of LOC on individual learning. We provide theoretical contributions and suggestions for managers in the light of our results.     

Selective Schools

This paper studies how schooling admission tests affect economic performance in an economy where individuals are endowed with both academic and non‐academic abilities and both abilities matter for labour productivity. We develop a simple model with schools run by the goverment, where individuals signal their abilities by taking an admission test and sort into low quality and high quality schools. When abilities are poorly correlated in the population, as documented in the literature, a standard test based only on academic abilities can be less efficient than a balanced test, which considers both ability types. We show that a sequential testing strategy, with schools testing academic abilities and firms testing non‐academic abilities on the sub‐sample of graduates of high quality schools, does not necessarily replicate the outcome of a balanced test.     

Efficiency and regulation in the case of the Swiss Private Railways

This paper discusses the efficiency of the Swiss Private Railways in an economic and regulatory context. For this purpose, scale efficiency and overall cost efficiency for 48 Swiss private railway companies are investigated. A translog cost function for a four-year panel is estimated and measures of economies of scale and density are derived. A compound indicator for network size and structure is introduced. The estimation results allow for a discussion of efficiency in terms of optimal scale and density. Overall cost efficiency is estimated by means of a frontier cost function. The findings on efficiency are discussed in the Swiss political and regulatory context. More specifically, a regression on the influence of ownership and subsidy structure on the efficiency is performed. The findings are that most of the Swiss private railway companies operate at an inappropriately low scale and density. While the companies are rather homogenous in terms of overall cost efficiency, evidence is found for a significant influence of regulation in terms of the subsidy structure.     

Stratified or Comprehensive? The Economic Efficiency of School Design

We study the efficiency of secondary school design by focusing on the degree of differentiation between vocational and general education. Using a simple model of endogenous job composition, we analyze the interaction between relative demand and relative supply of skills and characterize efficient school design when the government runs schools and cares about total net output. We show that neither a comprehensive nor a stratified system unambiguously dominates the other system in terms of efficiency for all possibile values of the underlying parameters. Since comprehensive systems generate more equal labour market outcomes, it follows that the relationship between efficiency and equity in secondary education is not necessarily a trade off.
