Sparse models, though long preferred and pursued by social scientists, can be ineffective or unstable relative to large models, for example, in economic predictions (Giannone et al., 2021). To achieve sparsity for economic interpretation while exploiting big data for superior empirical...

Using harmonized micro data, this paper investigates the job search methods of the unemployed in Europe. The analysis focuses on the importance of individual and household characteristics in this context, as well as on cross-country differences in Europe. Our findings suggest that both...

The article compares forecast quality from two atheoretical models. Neither method assumed a priori causality and forecasts were generated without additional assumptions about regressors. Tendency survey data was used within the Bayesian averaging of classical estimates (BACE) framework and...

The varieties of capitalism approach (VoC) and the related research assume that German firms adopt an internal flexibility profile that corresponds with the national institutional framework. Recent empirical studies, however, have found substantial diversity in realized firm-level strategies....

The relation between ports and their cities have evolved: it is no longer evident that well-functioning ports have automatically a net positive impact on the port-city. There are various trajectories and many ports and port-cities attempt to stimulate port-city development by a range of public...

We study positional portfolio management strategies in which the manager maximizes an expected utility function written on the cross-sectional rank (position) of the portfolio return. The objective function reflects the manager's goal to be well-ranked among competitors. To implement positional...

We derive asymptotic properties of estimators and test statistics to determine - in a grouped data setting - common versus group-specific factors. Despite the fact that our test statistic for the number of common factors, under the null, involves a parameter at the boundary (related to unit...

Before the coronavirus epidemic and the related lockdowns, the EU countries represented various image of social, fiscal and external economic characteristics which is the base of the cluster analysis. The puzzle is whether the pre-crisis preparedness results in different or similar damages...

The U.S. population has become increasingly concentrated in large metropolitan areas. However, there are striking differences in between the performances of big cities: some of them have been very successful and have been able to pull away from the rest, while others have stagnated or even...

This analysis of the 2020 OECD multidimensional fragility framework is a background paper for States of Fragility 2020. It provides a snapshot of the state of fragility in the world today, paying particular attention to the 57 fragile contexts on the framework. The paper starts by unpacking the...
