THE ECONOMIC RELATIONSHIP BETWEEN EXCHANGE RATE AND MONEY SUPPLY AND THEIR IMPACT ON AGRICULTURAL PRODUCTS IN IRAQ

The Iraqi Journal of Agricultural science, 2023
This research aimed to measure and analyze the impact of exchange rate shocks on some variables of the Iraqi economy during (1990-2022), because of the different effects of these shocks on the macroeconomic variables represented in money supply and ...

MEAN–VARIANCE PORTFOLIO MANAGEMENT WITH FUNCTIONAL OPTIMIZATION [PDF]

International Journal of Theoretical and Applied Finance, 2020
This paper introduces a new functional optimization approach to portfolio optimization problems by treating the unknown weight vector as a function of past values instead of treating them as fixed unknown coefficients in the majority of studies. We first show that the optimal solution, in general, is not a constant function.

Variance analysis and linear contracts in agencies with distorted performance measures [PDF]

, 2007
This paper investigates the role of variance analysis procedures in aligning objectives under the condition of distorted performance measurement. A riskneutral agency with linear contracts is analyzed, whereby the agent receives postcontract, pre ...

On $\mathbb{T}$-Transformation of Probability Measures

Mathematics
The concept of the (T=(s,t))-transformation of probability measures, introduced for s>0 and t∈R, is examined in this work from the perspective of Cauchy–Stieltjes kernel (CSK) families and their related variance functions (VFs).

Model-independent hedging strategies for variance swaps [PDF]

, 2011
A variance swap is a derivative with a path-dependent payoff which allows investors to take positions on the future variability of an asset. In the idealised setting of a continuously monitored variance swap written on an asset with continuous paths, it ...

Studies on the Marchenko–Pastur Law

Mathematics
In free probability, the theory of Cauchy–Stieltjes Kernel (CSK) families has recently been introduced. This theory is about a set of probability measures defined using the Cauchy kernel similarly to natural exponential families in classical probability ...

Effects of variance-function misspecification in analysis of longitudinal data

, 2005
The approach of generalized estimating equations (GEE) is based on the framework of generalized linear models but allows for specification of a working matrix for modeling within-subject correlations.

Some Results on the Free Poisson Distribution

Axioms
Let K+(μi)={Qsiμi,si∈(m0μi,m+μi)}, i=1,2, be two CSK families generated by the nondegenerate probability measures μ1 and μ2 with support bounded from above.
