Abstract:
Spatially and temporally varying adaptive inflation algorithms have been developed to combat the loss of variance during the forecast due to various model and sampling errors. The adaptive Bayesian scheme of Anderson uses available observations to update the Gaussian inflation distribution assigned for every state variable. The likelihood function of the inflation is computed using model-minus-data innovation statistics. A number of enhancements for this inflation scheme are proposed. To prevent excessive deflation, an inverse gamma distribution for the prior inflation is considered. A non-Gau

Abstract:
The Bolivian inflation process is analyzed utilizing a time-varying univariate and multivariate Markov-switching model (TMS). With monthly data and, beginning in the late 1930s, inflation is accurately described by a univariate TMS. The intercept for the high-inflation regime is significantly higher than for the low-inflation regime and the actual inflation rate mirrors the smoothing probabilities of the Markov process. Additionally, the predicted duration of each regime closely fits the periods when the country experienced low and inordinate high inflation rates. From a long-run perspective a

Abstract:
In ensemble Kalman filters, the underestimation of forecast error variance due to limited ensemble size and other sources of imperfection is commonly treated by empirical covariance inflation. To avoid manual optimization of multiplicative inflation parameters, previous studies proposed adaptive inflation approaches using observations. Anderson applied Bayesian estimation theory to the probability density function of inflation parameters. Alternatively, Li et al. used the innovation statistics of Desroziers et al. and applied a Kalman filter analysis update to the inflation parameters based on

In the first case, the alternative hypothesis must be based on the common mean shift model, while in the second case, the variance inflation model is appropriate.

The study aims to find the short-run empirical analyses of the impact of oil price fluctuation on the monetary instrument (Exchange rate, Inflation, Interest rate) in Nigeria. We explored the frequently used Toda–Yamamoto model (TY) model, by adopting the TY Modified Wald (MWALD) test approach to causality, Forecast Error Variance Decomposition (FEVD) and Impulse Response Functions (IRFs).The study covered the period 1995 to 2018 (monthly basis), and our findings from MWALD test indicated that there is a uni-directional causality of the log of oil price (lnoilpr) to log of the exchange rate (lnexchr) at 10% level of significance, also there is a contemporaneous response of log of consumer price index (lncpi) to log of exchange rate (lnexchr) and log of interest rate (lnintr), and jointly (lnoilpr, lncpi and lnintr) granger cause lncpi. Also at 5% level of significance lnintr responded due to positive change in lnoilpr and lnexchr, and jointly causes lnintr at 5% level of significance. This is complimented with our findings in FEVDs, and IRFs. The empirical analyses shows that oil price is a strong determining factor of exchange rate, cost of borrowing and directly influences inflationary or deflationary tendencies in Nigeria..

Abstract:
The purpose of the chapter is twofold. Firstly, the authors intend to identify the main determinants of Greenfield FDI in a context of political and economic changes by choosing inflation, trade freedom, and investment freedom as macroeconomic variables and political instability as an institutional variable. Secondly, they determine which environmental sector may affect this mode of foreign investment in MENA region. Using dynamic panel models on a sample of 13 countries over the period 2010-2018, they perform econometric modeling to measure the relationship between Greenfield FDI, macroeconomic aggregates, and the relationship between FDI and the environmental sector. They find that trade openness stimulates foreign investment in MENA region and that the lack of inflation control may disrupt the inflow of Greenfield FDI since it reflects the economic stability of the host countries. Furthermore, there is a positive relationship between Greenfield FDI and environmental sectors. The chapter suggests some relevant practical implications to improve the attractiveness of Greenfield FDI in the MENA region.

The dependent variable is the monthly violent crime rates and the independent variables are unemployment rates and inflation. This chapter discusses several topics related to the robustness of estimated models, such as how to prewhiten a time series, how to deal with trends and seasonal components, how to deal with autoregressive residuals, and how to discern changes of the dependent variable caused by independent variables from its simple continuity. This chapter also discusses the concepts of co-integration and long-memory effect and related topics such as error correction models and autoregressive distributive lags models.

The purpose of this chapter is to study the determinants of market capitalization and to investigate the impact of determinants of market capitalization. This chapter uses secondary data from 2003-2016 relating to market capitalization, income per capita, stock market liquidity, etc. The study employed descriptive test and normality test to describe the basic features of data and their distribution. The multicollinearity test has also been used to check the interdependence among independent variables. Multiple regression statistics has been used to determine the impact of independent variables on dependent variable. The results show that there is a positive impact of determinants on development of stock market except political risk and inflation. The findings will help stock market authority, individuals, and companies to understand the factors that affect share prices.

Abstract:
One of the crucial parts of globalization is the upsurge in the volume of Foreign Direct Investment (FDI) inflows across economies. Thus, it becomes inevitable for the mutual benefit of the countries among themselves as it promotes economic cooperation between them. Due to the favorable demography and increasing population size, MINT economies (Mexico, Indonesia, Nigeria, and Turkey) gain particular attention to FDI for GDP growth. Hence, this chapter analyzes the paramount determinants of GDP growth of MINT economies in the period of 2000-2019. To fulfill the purpose of the study, a linear regression model and pooled data analysis statistical technique are employed. GDP is taken as a dependent variable, while some key factors like inflation, unemployment, FDI, and trade openness are taken as independent variables.
