In this article we develop a tractable procedure for testing strict stationarity in a double autoregressive model and formulate the problem as testing if the top Lyapunov exponent is negative. Without strict stationarity assumption, we construct a consistent estimator of the associated top...

We examine the high volume return premium across countries as a test of the investor recognition hypothesis. Our cross-country tests are consistent with the hypothesis in that we find the magnitude of the premium is associated with market characteristics that relate to the importance of a...

Performance-based contracts (PBC) have become ubiquitous in industries ranging from aerospace and defense to computer support services. Despite advantages of paying for performance under PBC that have been highlighted in many previous studies, the more traditional Transaction-based Contracts...

We introduce a supply chain network equilibrium model with differentiated products, in which firms compete on product quantities and quality. We then extend the model to include a strict quota or tariff. We establish the equivalence between the model with a strict quota and that with a tariff,...

In this paper, we present a pharmaceutical supply chain network model with outsourcing under price and quality competition, in both equilibrium and dynamic versions. We consider a pharmaceutical firm that is engaged in determining the optimal pharmaceutical flows associated with its supply chain...

In this paper, we develop a new generalized network model for the optimization of the complex operations of medical nuclear supply chains in the case of the radioisotope molybdenum, with a focus on minimizing the total operational cost, the total waste cost, and the risk associated with this...

In this paper, we develop a general multitiered supply chain network equilibrium model consisting of competing suppliers and competing firms who purchase components for the assembly of their final branded products and, if capacity permits, and it enhances profits, produce their own components....

In this paper, a spatial price equilibrium model with information asymmetry in quality is developed. Producers at the supply markets are aware of the quality of their products, whereas consumers, located at the demand markets, are aware only of the average quality of the products that are...
