This work employs the Autoregressive Distributed Lag (ARDL) approach to investigate the nexus between macroeconomic variables and inflation in Madagascar. The findings reveal significant impacts of various factors, including imports, GDP, exchange rates, and oil prices, on inflation dynamics....

The purpose of the study is to examine the relationship between income inequality and environmental degradation in ASEAN-6 countries namely Indonesia, Malaysia, the Philippines, Thailand, Singapore, and Vietnam. It also provide analysis from the Islamic perspective based on result of the...

The depreciation of the national currency, the higher wage costs passed on to prices and the growing external debt, has characterized the Tunisian economy for almost a decade. In this context we investigate its inflation dynamics to understand which variables affects it in the short and the long...

state spaces with periodically time-varying transition probabilities is introduced. The finite-dimensional probability distributions of these time-periodic chains are first studied and their correspondence with the marginal distributions and transition probabilities is shown. Then, the concepts...

A unified theory of periodically homogeneous Markov chains on countable state spaces with periodically time-varying transition probabilities is introduced. The finite-dimensional probability distributions of these time-periodic chains are first studied and their correspondence with the marginal...

This book presents the history of economic thought as it relates to today’s most pressing problems, and it emphasizes the critical connection that exists between what may seem cold, unrealistic mathematical economic models, and the quality of everyday life of any citizen of the planet earth....

Multivariate GARCH models are in principle able to accommodate the features of the dynamic conditional correlations processes, although with the drawback, when the number of financial returns series considered increases, that the parameterizations entail too many parameters.In general, the...

We consider volume weighted average price (VWAP) as the 1st market-based statistical moment and derive the dependence of higher statistical moments of price on statistical moments and correlations of the values and volumes of market trades. If all trade volumes are constant during the averaging...

This paper introduces a two-step procedure for convex penalized estimation in dynamic location-scale models. The method uses a consistent, non-sparse first-step estimator to construct a convex Weighted Least Squares (WLS) optimization problem compatible with the Least Absolute Shrinkage and...

The origin of entropy dates back to 19th century. In 1948, the entropy concept as a measure of uncertainty was developed by Shannon. A decade after in 1957, Jaynes formulated Shannon’s entropy as a method for estimation and inference particularly for ill-posed problems by proposing the so...
