Equity-based crowdfunding is an increasingly popular source to fund start-ups. In equity-based crowdfunding, a form of crowdsourcing, many crowdfundees collectively fund a start-up by providing parts of the requested funding in prospect of financial returns.

This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the average productivity of survivors increases. These pro-competitive effects of import penetration on the...

In recent years considerable progress has been made in several aspects of the investigation of the photon structure. A recent review of the status of this field of research can be found in. In this paper, the most important results presented at Ascona are briefly reviewed. Of course the material presented is intended only as an overview, and reflects my personal view. For further information of...

Various types of Technology Credit Guarantees (TCGs) have been issued to support technology development of start-up firms. Technology evaluation has become a critical part of TCG system. However, general technology credit scoring models have not been applied reflecting the special phenomena of start-ups, which are distinguishable from those of established firms. Furthermore, somewhat complicate...

In recent years, several countries and organisations increased their e↵orts on the use of renewable energy and electromobility [1]. Reaching the goal of a more environmentfriendly energy production together with less expensive transportation by using electromobility concepts is much more complicated as expected. Energy from renewable energy sources (e.g., wind or water) have the disadvantage of...

We develop a dynamic optimal control model of a fashion designer’s challenge of maintaining brand image in the face of short-term pro…t opportunities through expanded sales that risk brand dilution in the longer-run. The key state variable is the brand’s reputation, and the key decision is sales volume. Depending on the brand’s capacity to command higher prices, one of two regimes is observed. ...
