Asymmetric information models predict comovements among trade characteristics such as returns, bid-ask spread, and trade volume on one hand and the trading intensity on the other hand. In this paper we investigate empirically the two-sided causality between trade characteristics and trading intensity. We apply a VAR-model for returns, bid-ask spread, trade volume, and trading intensity to trans...

Classic studies of spot price fluctuations for commodities like cotton and wheat have been interpreted using a power-law probability distribution with exponent alpha inside the Lévy-stable regime (0<alpha<2). In contrast price fluctuations for stocks have been interpreted using a power-law probability distribution with alpha outside the Lévy-stable regime suggesting that stock prices are in a d...

We investigate whether managers in outsourcing firms, through their prior experience in managing similar strategic alliances and prior association with the provider, learn to create value in their outsourcing relationships. Value creation is estimated in terms of long-term abnormal stock returns to the outsourcing firm relative to an industry, size and book-to-market matched sample of control f...

This paper examines three channel policies that are used in declining price environments: Price protection (P) is a mechanism under which the manufacturer pays the retailer a credit applying to the retailer’s unsold inventory when the wholesale price drops during the life cycle; midlife returns (M) allow the retailer to return units partway through the life cycle at some rebate; and end-of-life...

We consider the robust hedging problem in which an investor wants to super-hedge an option in the framework of uncertainty in a model of a stock price process. More specifically, the investor knows that the stock price process is H -self-similar with H ∈ (1/2, 1), and that the log-returns are Gaussian. This leads to two natural but mutually exclusive hypotheses both being self-contained to fix ...

The VAR-GARCH(1,1) price discovery model developed and tested with ASX data represents an extension of both the Chordia, Roll and Subrahmanyam (2005) and Hasbrouck (1991) models. The VAR-GARCH(1,1) price discovery model functions in accordance with the explanation for price discovery described by Chordia, Roll and Subrahmanyam (2005). This model allows the causal relationships between order flo...

In this paper, we aim to model the vertical relation between retailers and suppliers in the food industry whereby retailers exercise seller power in their relation with consumers and buyer power in their relation with producers. We then evaluate the degree of price transmission, relative to the perfectly competitive benchmark, from the farm to the retail sector assuming a supply shock. With the...

In this paper we re-examine the question of the excessive implied persistence of volatility estimates when GARCH-type models are used. We consider ten actively traded US stocks and we con rm the already established result in the literature that, when volume traded is inserted in the GARCH(1,1) or EGARCH(1,1) models for returns, the estimated persistence decreases. Since we feel that volume is a...

We present an artificial stock market in which simple trading agents enter an asynchronous double auction market to trade in a single stock. Beginning with a population of random trading agents drawing their bid prices from a normal distribution around the current price, we compare the statistical properties of the emergent stock price return distribution to that observed on a real price series...
