The creation of the China-led AIIB has been the most important event in the international financial sphere in recent years, but the comments about it have often been made from a multitude of lenses, thus complicating the recognition of its real implication. By clarifying the inclinations...

We study a two-period supply chain in which a manufacturer produces a product, learns to reduce cost, and sells it through a retailer with a price-dependent demand. The manufacturer's second-period production cost declines linearly in the first-period production with a random learning rate. The...

We study a firm's sourcing strategy when facing two unreliable suppliers and a price-dependent isoelastic demand. At optimality, the firm always orders at least from the low-cost supplier. The firm also orders from the high-cost supplier if and only if the effective purchase cost from the...

Dynamic Stackelberg game models have been used to study sequential decision making in noncooperative games in various fields. In this paper we give relevant dynamic Stackelberg game models, and review their applications to operations management and marketing channels. A common feature of these...

We develop an equilibrium model in a two-country, two-good, pure exchange economy in which investors with logarithmic utility functions have heterogeneous beliefs about exogenously given output or endowment processes. We obtain closed-form representations of real exchange rate and of stock...

In a pure-exchange, continuous-time economy, agents, who have different subjective discount rates and heterogenous beliefs on the fundamentals, trade with each other motivated not only by the benefit of risk sharing but also by speculation. This aggressiveness in trading can increase stock price...

This paper extends the Lucas (1978) model to a setting in which investors have heterogeneous beliefs about the structure of a dividend process. By assuming that all investors have logarithmic preferences and different subjective discount rates, we can obtain a closed-form representation of the...

The optimal contracts in portfolio delegation are characterized when the underlying state variable is not contractible and the principal must rely on the final wealth of portfolios to design compensation schemes for the fund manager. We show that finding the optimal contracts for general utility...

There is a large and growing literature on how to model the dynamics of the default-free term structure to fit the observed historical data. Much less is known about how best to model the dynamics of defaultable yield curves. This paper develops a class of defaultable term structure models that...

We investigate the role of index bonds in a dynamic consumption and asset allocation model where the rate of real consumption at any given time cannot fall below a fixed level. An explicit form of the optimal consumption and portfolio rule for a class of Constant Relative Risk Aversion (CRRA)...
