More Competition, Better Products: Evidence From Tariff Cuts

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT This article examines how increased competition affects product and process innovation. I combine plausibly exogenous variation in foreign competition induced by large tariff cuts with a difference‐in‐differences strategy and find that firms increase their product patenting in response to increased foreign competition, but, on average, foreign

First attempt at using a synthetic diet in short‐lived killifish, a vertebrate model of ageing

Journal of Fish Biology, EarlyView.
Abstract Diet standardization of model organisms is crucial for experimental consistency and repeatability in laboratory research, yet laboratory fish often lack species‐specific, open‐formula standardized diets. This study aims to address this gap by testing the effect of macronutrient content on the performance of Nothobranchius furzeri, an ...

Experimentally testing the function of anal fins in the bluefin killifish, Lucania goodei

Journal of Fish Biology, EarlyView.
Abstract Anal fins are thought to affect many functions, including swimming, sperm flow and signalling. However, there are few experimental demonstrations of these functions. We manipulated male anal fins by placing a cut in the fin. We found that cut males had lower fertilization rates than uncut males.

Daily entry and exit triggers for open market repurchases

Journal of Financial Research, EarlyView.
Abstract Using publicly available daily data, we analyse the daily decision repurchasing firms make to enter or exit the market during open market repurchase programs. Firms enter the market to repurchase after a stock price downturn and maintain their presence in the market while stock returns remain negative. The lower the preceding overnight return,

Determining bismuth content in GaAsBi alloys by energy‐dispersive X‐ray spectroscopy: A case study with multiple sets of k*‐factors for analytical transmission electron microscopy

Journal of Microscopy, EarlyView.
Abstract Measuring the bismuth (Bi) content of ternary gallium arsenide bismuthide (GaAsBi) alloys is important because it sensitively influences their bandgap, and Bi is known to segregate vertically to the surface and sometimes also laterally during growth, so elemental distribution maps need to be quantified.
