Aggregate Versus Disaggregate Data in Measuring School Quality

This article develops a measure of efficiency to use with aggregated data. Unlike the most commonly used efficiency measures, our estimator adjusts for the heteroskedasticity created by aggregation. Our estimator is compared to estimators currently used to measure school efficiency. Theoretical results are supported by a Monte Carlo experiment. Results show that for samples containing small schools (sample average may be about 100 students per school but sample includes several schools with about 30 or less students), the proposed aggregate data estimator performs better than the commonly used OLS and only slightly worse than the multilevel estimator. Thus, when school officials are unable to gather multilevel or disaggregate data, the aggregate data estimator proposed here should be used. When disaggregate data are available, standardizing the value-added estimator should be used when ranking schools.     

Exchange Rates and the Conversion of Currency‐Specific Risk Premia

How do the risk factors that drive asset prices influence exchange rates? Are the parameters of asset price processes relevant for specifying exchange rate processes? Most international asset pricing models focus on the analysis of asset returns given exchange rate processes. Little work has been done on the analysis of exchange rates dependent on asset returns. This paper uses an international stochastic discount factor (SDF) framework to analyse the interplay between asset prices and exchange rates. So far, this approach has only been implemented in international term structure models. We find that exchange rates serve to convert currency‐specific discount factors and currency‐specific prices of risk – a result linked to the international arbitrage pricing theory (IAPT). Our empirical investigation of exchange rates and stock markets of four countries presents evidence for the conversion of currency‐specific risk premia by exchange rates.     

Knowledge transfer across permeable boundaries: An empirical study of clients’ decisions to involve management consultants

We investigate the relationship between the knowledge requirements of projects and clients’ decisions whether to procure services from external management consultants for the execution of these projects. Using data from interviews with client decision-makers regarding the execution of 86 projects, we find that knowledge requirements are strongly associated with the decision whether or not to involve external consultants. The results highlight the closeness of the relationships between clients and consultants, supporting Kitay and Wright's [Kitay, J., & Wright, C. (2004). Take the money and run? Organisational boundaries and consultants’ roles, The Service Industries Journal, 24(3) 1–18] view of the permeability of the boundaries between many client organizations and their consultants. The findings also confirm our expectation that clients use the services of external management consultants in order to procure functional or industry-specific knowledge which consultants can pool and apply efficiently across many projects.     

Why Are Mothers Working Longer Hours in Austria than in Germany? A Comparative Microsimulation Analysis*

Labour force participation rates of mothers in Austria and Germany are similar; however, full‐time employment rates are much higher among Austrian mothers. In order to find out to what extent these differences can be attributed to differences in the tax‐transfer system, we perform a comparative microsimulation exercise. After estimating structural labour supply models for both countries, we interchange two important institutional characteristics of the two countries ‐ namely, (i) the definition of the tax unit within the personal income tax and (ii) the parental leave benefit scheme. As our analysis shows, differences in mothers’employment patterns can partly be explained by the different tax systems: while Germany has a system of joint taxation with income splitting for married couples, Austria taxes everyone individually, which leads to lower marginal tax rates for secondary earners than in the German system.
