This paper examines the determinants of stock returns in a small open economy using an APT framework. The analysis is conducted for the Swiss stock market which has the particularity of including a large proportion of firms that are exposed to foreign economic conditions.

The market model of interest rates specifies simple forward or Libor rates as lognormaly distributed, their stochastic dynamics has a linear volatility function. This model is extended to quadratic volatility which is the product of a quadratic polynomial and a level-independent covariance...

The basic model of financial economics is the Samuelson model of geometric Brownian motion because of the celebrated Black-Scholes formula for pricing the call option. The assets volatility is a linear function of the asset value and the model garantees positive asset prices. In this paper it is...

Non-fundamental demand shocks have significant effects on asset prices, but observing these shocks is challenging. We use the exchange traded fund (ETF) primary market to study non-fundamental demand. Unique to the ETF market, specialized arbitrageurs called authorized participants correct...

Forward foreign exchange contracts embed not only expected depreciation but also a sizable premium, which complicates inferences about anticipated returns. This study derives arbitrage-free affine forward currency models (AFCMs) with closed-form expressions for both unobservable variables. Model...

Sovereigns are active issuers both of foreign and domestic debt. The former, composed mainly of internationally traded hard currency denominated Eurobonds, serves as a direct benchmark for the creditworthiness of the country. The latter, represented by local treasuries, although considered a...

Stock markets play a key role in corporate financing in Asia. However, despite their increasing importance in terms of size and cross-border investment activity, the region's markets are reputed to be more “idiosyncratic” and less reliant on economic and corporate fundamentals in their...

I show that an important no-arbitrage consistent but costly collateral rental yield contributes to about two-thirds of the standard CIP violations. I measure this yield using two approaches applied to short- and long-term CIP horizons. First, I assume that the yield is observable and proxy it...

We develop a theory of arbitrage-free dispersion (AFD) that characterizes the testable restrictions of asset pricing models. AFD measures Jensen's gap in the cumulant generating function of pricing kernels and returns. It implies a wide family of model-free dispersion constraints, which extend...

We develop a model in which financially constrained arbitrageurs exploit price discrepancies across segmented markets. We show that the dynamics of arbitrage capital are self-correcting: following a shock that depletes capital, returns increase, and this allows capital to be gradually...
