    Hidden Skewness

    Multiplicative growth processes that are subject to random shocks often have a skewed distribution of outcomes. A simple laboratory experiment shows that participants either strongly underestimate skewness or ignore it completely. The participants' choices reveal bounds on their subjective medians of a financial asset's price that is subject to stochastic growth. The observed bias in expectations is ...

    Prepared to Plan? A Snapshot of Researcher Readiness to Address Data Management Planning Requirements

    Objective. Cornell University's Research Data Management Service Group (RDMSG) surveyed NSF principal investigators (PIs) at Cornell in order to understand how well-prepared researchers are to meet the new NSF data management planning requirement, to build our own understanding of the potential impact on campus services, and to identify service gaps.. - Methods - We administered a 43-question online ...

    Forecasting the Prices and Rents for Flats in Large German Cities

    In this paper, we make multi-step forecasts of the monthly growth rates of the prices and rents for flats in 26 largest German cities. Given the small time dimension, the forecasts are done in a panel-data format. In addition, we use panel models that account for spatial dependence between the growth rates of housing prices and rents. Using a quasi out-of-sample forecasting exercise, we find that both ...

    In-Sample and Out-of-Sample Prediction of Stock Market Bubbles: Cross-Sectional Evidence

    We evaluate the informational content of ex post and ex ante predictors of periods of excess stock (market) valuation. For a cross section comprising 10 OECD economies and a time span of at most 40 years alternative binary chronologies of price bubble periods are determined. Using these chronologies as dependent processes and a set of macroeconomic and financial variables as explanatory variables, ...

    Comparing the Predictive Power of Subjective and Objective Health Indicators: Changes in Hand Grip Strength and Overall Satisfaction with Life as Predictors of Mortality

    Self-reported measures of health are generally treated as weak measures of respondents' objective health status. On the other hand, most surveys use self-reported health to measure health status and to determine the effects of a range of other socio-economic characteristics of the local environment on individual health. It is therefore of interest to the public health research community to verify the ...

    Unobservable, but Unimportant? The Influence of Personality Traits (and Other Usually Unobserved Variables) for the Evaluation of Labor Market Policies

    Many commonly used treatment effects estimators rely on the unconfoundedness assumption (“selection on observables") which is fundamentally non-testable. When evaluating the effects of labor market policies, researchers need to observe variables that affect both treatment participation and labor market outcomes. Even though in many countries it is possible to access (very) informative administrative ...

    Eine bessere Wettbewerbspolitik steigert das Produktivitätswachstum merklich

    Dass zwischen der Qualität der Wettbewerbspolitik und dem Produktivitätswachstum eines Landes ein Zusammenhang besteht, wird in der Wirtschaftswissenschaft seit langem diskutiert. Es ist jedoch sehr schwierig, diesen Zusammenhang genau nachzuweisen, größenmäßig zu bestimmen oder zu beziffern. Ein internationales Forscherteam unter wissenschaftlicher Leitung des DIW-Wettbewerbsexperten Tomaso Duso hat ...
