The heptathlon comprises the results of seven single disciplines, assuming an equal influence from each discipline, depending on the measured performance. Data analysis was based on the data recorded for the individual performances of the 10 winning heptathletes in the World Athletics Championships from 1987 to 2013 and the Olympic Games from 1988 to 2012. In addition to descriptive analysis me...

Recent developments in nonlinear panel data analysis allow identifying and estimating general dynamic systems. In this review we describe some results and techniques for nonparametric identification and flexible estimation in the presence of time-invariant and time-varying latent variables. This opens the possibility to estimate nonlinear reduced forms in a large class of structural dynamic mod...

The consistent effect of education on volunteering has been explained in a number of ways. In this study we test the hypothesis that perceived control beliefs are partly responsible. Using two waves of panel data from National Survey of Midlife in the United States we estimated cross-lagged structural equation models in which education is positioned as the exogenous variable and perceived contr...

Drawing on 18 years of panel data for the 89 most research-intensive US universities, this paper examines changing relationships between commercial and academic systems for the dissemination and use of new scientific findings. Increased patenting and commercial engagement on US campuses, I argue, has dramatically altered the rules that govern inter-university competition. From once separate sys...

Critiques of the concept of key success factors have raised objections both conceptually and methodologically. From the latter perspective, common research practice is criticized for neglecting the influence of firm-specific, unobservable variables (e.g., management skills). To control for these effects a structural equation approach (“LISREL”) to the analysis of panel data is proposed. In an e...

In this paper we suggest panel data unit root tests which allow for a potential structural break in the individual e¤ects and/or the trends of each series of the panel, assuming that the time-dimension of the panel, T , is ...xed. The proposed test statistics consider for the case that the break point is known and for the case that it is unknown. Monte Carlo evidence suggests that they have siz...

We assess the sustainability of public finances in the EU15 using stationarity and cointegration analysis. Specifically, we use panel unit root tests of the first and second generation allowing in some cases for structural breaks. We also apply modern panel cointegration techniques developed by Pedroni (1999, 2004), generalized by Banerjee and Carrion-i-Silvestre (2006) and Westerlund and Edger...
