1. Separate cointegration in a VAR system subject to structural breaks

Subject:
empirical research,   etc   ; economics; models;     Show all 3 Subjects
Abstract:
... This note demonstrates that the analysis of separate cointegration can be facilitated by properly allowing for regime shifts in the underlying data generation process. A vector autoregressive (VAR) model is reformulated in such a way that it is subject to deterministic breaks and also contains the structure of separate cointegration. A comparative empirical study shows the advantage of the propose ...

Abstract:
... The origin of life is surrounded by great mystery and difficult to answer since we only know the existence of life from our own globe Earth. However, it is important to understand how life arose and developed if we should understand biodiversity and mass extinctions to day. The present Discussion try shed light on this and discuss the newest finding and theories. ...

Abstract:
... Is the supply of researchers or the demand for technologies more important for innovation? The supply of research labor captures a scale effect, whereas the demand from production labor for technologies captures a market-size effect. We find that both the scale effect and the market-size effect are important for innovation and their relative importance depends on R&D labor intensity. We collect da ...

4. On CCE estimation of factor-augmented models when regressors are not linear in the factors

Author:

Subject:
empirical research,   etc   ; economics; models;     Show all 3 Subjects
Abstract:
... In empirical research it is often of interest to include non-linear functions of the explanatory variables, such as squares or interactions, in the specification. A popular technique to estimate such models in the presence of common factors is the Common Correlated Effects (CCE) methodology. However, this approach assumes that the regressors are linear in the factors, which is not the case if vari ...

empirical research,   etc   ; models; statistics;     Show all 3 Subjects
Abstract:
... Hypothesis testing for finite mixture model has long been a challenging problem. The standard likelihood ratio test (LRT) does not have the usual asymptotic χ2 distribution partly because the mixture model is not identifiable under null hypothesis. A simple class of hypothesis test procedures for finite mixture models based on goodness of fit (GOF) test statistics is investigated. The suggested hy ...

Abstract:
... In summary (“two-step”) coalescent analyses of empirical data, researchers typically apply the bootstrap to quantify branch support for clades inferred on the optimal species tree. We tested whether site-wise bootstrap analyses provide consistently more conservative support than gene-wise bootstrap analyses. We did so using data from three empirical phylogenomic studies and employed four coalescen ...

Abstract:
... Several shortcomings with currently available pharmacotherapy of epilepsy necessitate the search for new drug targets. Paroxysmal depolarization shifts (PDS) represent the cellular correlates of electrographic (e.g. interictal) spikes. While the ionic basis of PDS is understood in great detail, controversy exists regarding their proposed implication in epilepsy. To address this issue and to consid ...

Abstract:
... Motivated by both analytical tractability and empirical practicality, community ecologists have long treated the species pair as the fundamental unit of study. This notwithstanding, the challenge of understanding more complex systems has repeatedly generated interest in the role of so‐called higher‐order interactions (HOIs) imposed by species beyond the focal pair. Here we argue that HOIs – define ...

Abstract:
... The substantial literature on environmental instrument choice under uncertainty has provided valuable insights using simplifying assumptions of linear marginal cost and benefit curves and additive error terms to determine when and why a price or quantity instrument should be preferred. But empirical analysis has shown that linearity and additivity are not the norm. This paper explores the formal p ...
