IRT‐based response style models and related methodology: Review and commentary
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract We provide a review and commentary on recent methodological research related to item response theory (IRT) modelling of response styles in psychological measurement. Our review describes the different categories of IRT models that have been proposed, their associated assumptions and extensions, and the varying purposes they can serve.

Cladistics, EarlyView.Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological

Estimating the total mortality of seabirds following a marine heat wave
Conservation Biology, EarlyView.Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

Life Cycle Consumption and Portfolio Choice Under Real Interest Rate Risk
Financial Management, EarlyView.ABSTRACT We set up a life cycle model with real interest rate risk to demonstrate that real interest rates have implications for optimal household consumption and investments. Lower interest rates lead to higher optimal stock investments and lower consumption.

Dynamics of High‐Growth Young Firms and the Role of Venture Capitalists
International Economic Review, EarlyView.ABSTRACT Motivated by the substantial growth and upfront investments of venture capital (VC)‐backed firms observed in administrative US Census data, this study develops a life‐cycle firm dynamics model. In the model, startups choose the source of financing from VC, angel investors, or banks, depending on their growth potential, and invest in innovation.

Social Status, Inequality, and Redistribution
International Economic Review, EarlyView.ABSTRACT We explore implications of social status concerns for redistribution, income inequality, and growth in a political economy framework. Salience of such concerns leads to a propagation mechanism, whereby initial income inequality and reduced willingness to redistribute income reinforce each other, potentially giving rise to multiple steady ...
