Mean-variance efficient portfolios constructed using sample moments often involve taking extreme long and short positions. Hence practitioners often impose portfolio weight constraints when constructing efficient portfolios. Green and Hollifield (1992) argue that the presence of a single...

The paper models foreign capital inflow in a multi-period framework from the developed to the developing countries. The market for foreign loan together with the foreign exchange market simultaneously determines interest rate in the international loan market and the exchange rate. We also derive...

In this paper we look at the PBC problem through the lens of uncertainty. The feedback control used by us is the famous NKPC with stochasticity and wage rigidities. We extend the NKPC model to the continuous time stochastic set up with an Ornstein-Uhlenbeck process. We minimize relevant expected...

We provide various norm-based definitions of different types of cross-sectional dependence and the relations between them. These definitions facilitate to comprehend and to characterize the various forms of cross-sectional dependence, such as strong, semi-strong, and weak dependence. Then we...
