Characterizing order processes of continuous review (s,S) and (r,nQ) policies
Noblesse, Ann M.; Boute, Robert N.; Lambrecht, Marc R.; … - In: European Journal of Operational Research 236 (2014) 2, pp. 534-547
We provide a novel approach to characterize the order process of continuous review (s,S) and (r,nQ) inventory policies …, and study the impact of the batching parameter (the value of Q or S-s) on the variability in the order process. First, we … distribution and the value of the batching parameter. This may motivate a supplier to adjust his imposed fixed order cost to …

Quantifying the Bullwhip Effect in a Simple Supply Chain: The Impact of Forecasting, Lead Times, and Information
Chen, Frank; Drezner, Zvi; Ryan, Jennifer K.; … - In: Management Science 46 (2000) 3, pp. 436-443
An important observation in supply chain management, known as the bullwhip effect, suggests that demand variability increases as one moves up a supply chain. In this paper we quantify this effect for simple, two-stage supply chains consisting of a single retailer and a single manufacturer. Our...

Stochastic financial analytics for cash flow forecasting
Tangsucheeva, Rattachut; Prabhu, Vittaldas - In: International Journal of Production Economics 158 (2014) C, pp. 65-76
Accurate cash flow forecasting is essential for successful management of firms and it becomes especially critical during uncertain market and credit conditions. Without accurate cash flow forecasting, a firm may fail to meet its short-term obligations and risk bankruptcy. Accurate cash flow...

On the Estimation of Term Structure Models and An Application to the United States
International Monetary Fund (IMF); International … - 2010
This paper discusses the estimation of models of the term structure of interest rates. After reviewing the term structure models, specifically the Nelson-Siegel Model and Affine Term- Structure Model, this paper estimates the terms structure of Treasury bond yields for the United States with...

Transition and Regional Inequality in Russia; Reorganization or Procrastination?
Dolinskaya, Irina; Tytell, Irina - International Monetary Fund (IMF) - 2002
This paper analyzes the evolution of interregional income inequality during transition in Russia. The transition matrix approach reveals that between 1991 and 1997 income mobility tended toward a highly uneven long-term distribution with the majority of regions at low income levels and a...

Exchange Rate Regime Transitions
Masson, Paul R. - International Monetary Fund (IMF) - 2000
The “hollowing-out,” or “two poles” hypothesis is tested in the context of a Markov chain model of exchange rate transitions. In particular, two versions of the hypothesis—that hard pegs are an absorbing state, or that fixes and floats form a closed set, with no transitions to...

Recent Advances in Credit Risk Modeling
Gasha, Jose Giancarlo; Santos, Andre; Chan-Lau, Jorge A.; … - International Monetary Fund (IMF) - 2009
As is well known, most models of credit risk have failed to measure the credit risks in the context of the global financial crisis. In this context, financial industry representatives, regulators and academics worldwide have given new impetus to efforts to improve credit risk modeling for...

A Bayesian Approach to Model Uncertainty
Tsangarides, Charalambos G. - International Monetary Fund (IMF) - 2004
This paper develops the theoretical background for the Limited Information Bayesian Model Averaging (LIBMA). The proposed approach accounts for model uncertainty by averaging over all possible combinations of predictors when making inferences about the variables of interest, and it...

Imperfect Information and Saving in a Small Open Economy
Roitman, Agustin; Daude, Christian - International Monetary Fund (IMF) - 2011
Emerging markets are more volatile and face different types of shocks, in size and nature, compared to their developed counterparts. Accurate identification of the stochastic properties of shocks is difficult. We show evidence suggesting that uncertainty about the underlying stochastic process...
