Optimal Inventory Policies When the Demand Distribution is Not Known

Larson, Erik W.; Sharma, Sunil; Olson, Lars J. - International Monetary Fund (IMF) - 2000

This paper analyzes the stochastic inventory control problem when the demand distribution is not known. In contrast to previous Bayesian inventory models, this paper adopts a non-parametric Bayesian approach in which the firm’s prior information is characterized by a Dirichlet process prior....

The Effects of Monetary and Fiscal Policy on Aggregate Demand in a Small Open Economy; An Application of the Structural Error Correction Model

Konuki, Tetsuya - International Monetary Fund (IMF) - 2000

This paper empirically analyzes the short-run effects of monetary and fiscal policy on aggregate demand, using the two-step structural error correction method. This method has an advantage over the standard reduced-form error correction method in providing a meaningful interpretation for impulse...

Public Capital and Output Growth in Portugal; An Empirical Analysis

Ligthart, Johanna Elisabeth - International Monetary Fund (IMF) - 2000

The paper investigates the growth effects of public capital in Portugal using annual data for the period 1965-95. Both a production function and a vector autoregressive model are estimated. Public capital is shown to be a significant long-term determinant of output growth. The size of the...

$L_p$-Approximable sequences of vectors and limit distribution of quadratic forms of random variables

Mynbaev, Kairat - Volkswirtschaftliche Fakultät, … - 2000

concerning weighted sums of random variables, where the weights are nonstochastic sequences approximated in some sense by square …-integrable functions and the random variables are "two-wing" averages of martingale differences. The results constitute the first … central limit theorem for quadratic forms of random variables illustrates the method. …

Contagion, Monsoons, and Domestic Turmoil in Indonesia; A Case Study in the Asian Currency Crisis

Saxena, Sweta Chaman; Cerra, Valerie - International Monetary Fund (IMF) - 2000

This paper investigates whether Indonesia’s recent currency crisis was due to domestic fundamentals, common external shocks (“monsoons”), or contagion from neighboring countries. Markov-switching models attribute speculative pressure on Indonesia’s currency to domestic political and...

A hardware generator of multi-point distributed random numbers for Monte Carlo simulation

Bruti-Liberati, Nicola; Martini, Filippo; Piccardi, Massimo - In: Mathematics and Computers in Simulation (MATCOM) 77 (2008) 1, pp. 45-56

Monte Carlo simulation of weak approximations of stochastic differential equations constitutes an intensive computational task. In applications such as finance, for instance, to achieve “real time” execution, as often required, one needs highly efficient implementations of the multi-point...

Random strategies of contact tracking

Dybiec, Bartłomiej - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 19, pp. 4863-4870

One of several critical issues in the development of optimal disease containment and eradication strategies is the knowledge of underlying contacts between individuals. Here we employ random search strategies to identify all possible links, representing direct or indirect interactions between...

A meta‐analysis of effect sizes in international marketing experiments

Wang, Xuehua; Yang, Zhilin - In: International Marketing Review 25 (2008) 3, pp. 276-291

Purpose – Effect size is an important determinant of statistical power. However, very few experimental studies in international marketing (IM) report effect sizes and no meta‐analysis work in this regard has been done. The main objective of this paper, therefore, is to quantitatively...
