In differentiated product markets, the entry and exit of individual product models— rather than of firms—often serve as the main equilibrating force. Market structure changes that lead to high prices also tend to encourage entry, partially offsetting the effects. Thus, accurately predicting changes from a merger or bankruptcy should incorporate this(More)
In large scale biological experiments, like high-throughput or high-content cellular screening, the amount and the complexity of images to be analyzed are steadily increasing. To handle and process these images, well defined image processing and analysis steps need to be performed by applying dedicated workflows. Multiple software tools have emerged with(More)
The progression of breast cancer can be quantified in lymph node whole-slide images (WSIs). We describe a novel method for effectively performing classification of wholeslide images and patient level breast cancer grading. Our method utilises a deep neural network. The method performs classification on small patches and uses model averaging for boosting. In(More)
E-Learning ist schon länger als Lernmethode für Faktenwissen etabliert. Der Erfolg hängt jedoch von der Wiederholung und der Motivation des Nutzers ab. Gamifiziertes E-Learning hat den Anspruch genau diese Lücke zwischen Motivation und E-Learning zu schließen und die Lernleistung in Bezug auf Geschwindigkeit und Dauerhaftigkeit des Wissens zu erhöhen. Dazu(More)
Competing standards often proliferate in the early years of product markets, potentially leading to socially inefficient investment. This paper studies the effect of compatibility in the U.S. electric vehicle market, which has grown ten-fold in its first five years but has three incompatible standards for charging stations. I develop and estimate a(More)
Universities perform a rising share of R&D in developed countries and increasingly rely on internal rather than government or private sector sources to fund these activities. This paper uses unexpected college football outcomes to exogenously vary school-funded research support expenditures. It then examines how these expenditures affect scientific(More)
