Preemptive Entry and Technology Diffusion: The Market for Drive‐In Theaters

The RAND Journal of Economics, EarlyView.
ABSTRACT This article studies entry preemption in new industries. We first test a key prediction of dynamic entry games: Entry preemption is most relevant in intermediate‐sized markets, where firms face highest uncertainty about future entry. Using US drive‐in theater market (1945–1957) data, we find robust evidence for this non‐monotonic relationship ...

Geometric overdispersion facilitates the integration of ecological data

Methods in Ecology and Evolution, EarlyView.
Abstract Statistical data integration facilitates inference based on the variety of data prevalent in ecology. In particular, integrated distribution models (IDMs) have been proposed for inferring spatial patterns in abundance using combinations of noisy count, presence–absence and presence–only data.

Inferring alternative ecosystem states with field survey data

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Monetary Policy, Investor Sentiment and Stock Price Bubble: Evidence From China

Accounting &Finance, EarlyView.
ABSTRACT The empirical results indicate that an increase in interest rates may stimulate a significant and persistent stock price bubble, which is consistent with rational asset price bubble theory. This finding suggests that central banks should implement anti‐turbulent monetary policy with caution, since inappropriate tightening may unintentionally ...

“A Total Paradigm Shift”: Interviews With Australian Maternity Care Providers Who Practice Weight‐Inclusive Care

Birth, EarlyView.
ABSTRACT Background Weight stigma is pervasive in maternity care, contributing to negative health outcomes and disengagement among larger‐bodied women. To reduce weight stigma and promote respectful, individualized care, a weight‐inclusive approach prioritizes overall well‐being rather than focusing on weight as a key health indicator.
