We analyze the impact of funding costs and margin requirements on prices of index options traded on the CBOE. We propose a model that gives upper and lower bounds for option prices in the absence of arbitrage in an incomplete market with differential borrowing and lending rates. We show that...

The use of dictionaries in financial sentiment analysis and other financial and economic applications remains widespread because keyword-based methods appear more transparent and explainable than more advanced techniques commonly used in computer science. However, this paper demonstrates the...

Dieser Beitrag untersucht die potentiellen Beschäftigungseffekte von Direktinvestitionen der Unternehmen des Dienstleistungssektors für die Schweiz. In einer theoretischen Perspektive werden zunächst die Konsequenzen der Besonderheiten von Dienstleistungsgütern gegenüber Industriegütern...

This study analyses the extent and determinants of temporary employment in Switzerland and performs an evaluation of these contracts using data from the first three waves of the Swiss Household Panel (SHP), i.e. for the years 1999 to 2001. It is shown that temporary employment is most common...

Implementing performance pay requires that workers' output be measured. When measurement costs differ among firms, those with a measurement cost advantage choose to implement performance pay. They attract the best workers, and both the level and variability of compensation are higher at these...

This paper establishes the result that the seller prefers posted-price selling when the cost of information acquisition is high, and auctions when it is low. We view corporate bonds as an instance of the former case, and government bonds as an instance of the latter.

We explore the pricing of variance risk by decomposing stocks' total variance into systematicand idiosyncratic return variances. While systematic variance risk exhibits a negative priceof risk, common shocks to the variances of idiosyncratic returns carry a large positive riskpremium. This...
