- Cross-sectional error dependence in panel quantile regressionsPublication . Demetrescu, Matei; Hosseinkouchack, Mehdi; Rodrigues, Paulo M. M.; NOVA School of Business and Economics (NOVA SBE)This paper shows that cross-sectional dependence (CSD) is an indicator of misspecification in panel QR rather than just a nuisance that may be accounted for with panel-robust standard errors. This motivates the development of a novel test for panel QR misspecification based on detecting CSD. The test possesses a standard normal limiting distribution under joint N, T asymptotics with restrictions on the relative rate at which N and T go to infinity. A finite-sample correction improves the applicability of the test for panels with larger N. An empirical application illustrates the use of the proposed cross-sectional dependence test.
- Hot management trendsPublication . Ratten, Vanessa; Nanere, Marthin G.; Cunha, Miguel Pina e; Fujimoto, Yuka; Intezari, Ali; Garica-Fernández, Jerónimo; Dhakal, Subas; Omri, Waleed; Saura, Jose Ramon; Lux, Andrei; Sajjad, Aymen; Lisboa, Ana; D’Souza, Clare; NOVA School of Business and Economics (NOVA SBE); Cambridge University PressManagement practices are constantly changing amid intense competitive global pressure. This can put a strain on managers in terms of adapting to new challenges that arise from rapid transformations. While there is an emphasis on timely transformations in order to increase efficiency and productivity gains, there can also be a relaxation when managers have reached their pinnacle and achieved their goals. The goal of this editorial is to focus on hot management trends which is an important topic given the ever shifting business environment. Well-known academics were asked to write about what they see as the main management trends affecting society at the current time period. They each have diverse views based on their area of expertise and thought processes. For the Journal of Management & Organization, it is critical that we look into management trends in order to inform practice but also to enrichen theory. It is exciting times with many things happening regarding management that makes it exciting to read about what may occur in the future.

- The persistence of wagesPublication . Carneiro, Anabela; Portugal, Pedro; Raposo, Pedro; Rodrigues, Paulo M. M.; NOVA School of Business and Economics (NOVA SBE)This paper provides comprehensive and detailed empirical regression analyses of the sources of wage persistence. Exploring a rich matched employer-employee data set and the estimation of a dynamic panel wage equation with high-dimensional fixed effects, our empirical results show that permanent unobserved heterogeneity plays a key role in driving wage dynamics. The decomposition of the omitted variable bias indicates that the most important source of bias is the persistence of worker characteristics, followed by the heterogeneity of firms’ wage policy and last by the job-match quality. We highlight the importance of the incidental parameter problem, which induces a severe downward bias in the autoregressive parameter estimate, through both an in-depth Monte Carlo study and an empirical analysis. Using three alternative bias correction methods (the split-panel Jackknife (Dhaene and Jochmans, 2015), an analytical expression (Hahn and Kuersteiner, 2002), and a residual based bootstrap approach (Everaert and Pozzi, 2007, Gonçalves and Kaffo, 2015)), we observe that up to one-third of the reduction of the autoregressive parameter estimates induced by the control of permanent heterogeneity (high dimensional fixed effects) may not be justified.
- Organising through timePublication . Clegg, Stewart; Cunha, Miguel Pina e.; Harvey, Charles; Maclean, Mairi; Silva, Álvaro Ferreira da; NOVA School of Business and Economics (NOVA SBE); Taylor & FrancisThis special issue represents the first effort to bridge paradox theory and historical analysis further. Its goal is to create a fertile environment for advancing the historical study of organisations by contributing to discussions on various research topics where organisations, paradoxes, and temporality intersect. Defining organisational paradoxes as interdependent contradictions that persist over time contains an immediate plea for applying historical thinking and methodologies. The collection of papers included in this special issue illustrates that exploring paradoxes in business history is a promising research avenue.
