Covid-19 is an infectious disease caused by acute respiratory syndrome coronavirus 2 (severe acute respiratory syndrome coronavirus 2 or SARS-CoV-2). It makes the decrease of people's purchasing power. Meanwhile, the economic growth indicates the success of a country's economic development. Therefore, the Consumer Price Index occurs Inflation and D...

We study how individuals' formation of inflation expectations are affected by the stringent containment and economic support measures put in place during the COVID‐19 pandemic. Using the New York Fed Survey of Consumer Expectations (SCE) and the Oxford COVID‐19 Government Response Tracker (OxCGRT), we find that policies aimed at containing the pand...
Purpose
The purpose of this study paper is to focus on developing novel ways to monitor an economy in real time during the COVID-19 pandemic. A fully automated framework is proposed for collecting and analyzing online food prices in Poland. This is important, as the COVID-19 outbreak in Europe in 2020 has led many governments to impose lockdowns th...
This study aims to examine the effect of macroeconomics, namely the effect of Exchange Rate, Inflation, BI-7 Day Repo Rate, and Gold Price on the Construction Sector Stock Price Index listed on the Jakarta Islamic Index for the 2019-2021 period during the Covid-19 pandemic. The population used in this study are all those who are included in the bui...
This issue of the Future Europe Journal attempts to add content to the long-standing discussion about the necessary changes in the organisation of the monetary and banking union. Questions about the independence of the ECB during the pandemic vis-à-vis monetary strategy and a comparative analysis of bailout policies may give rise to suggestions for...
The paper addresses two main issues. What is the response of the Algerian exchange rate (REER) to the double whammy of COVID-19 and oil price collapse? To what extent can the previous combination spill over into the inflation rate? For this purpose, we use monthly data covering the period January 2010 to June 2021, and we run both ARDL and NARDL mo...

... This study presents the analysis of the WMC model in predicting the TB morbidity rate in Indonesia. Many researchers have used the WMC method to predict a quantity, including Yang et al. for the probability interval of wind power in China [13], Gui and Choi for precipitation in Yangzhou [14], Yan et al. for mobile phone user mobility in China [15], and Siregar et al. for the consumer price index in Medan [16]. All previous studies show a satisfactory result. ...
In this work, the Weighted Markov Chain (WMC) model for time series data forecasting is examined. The Markov Chain model has been generalized in this model. In order to forecast the morbidity rate in 2021, the WMC model was used to data on tuberculosis (TB) morbidity rates in Indonesia from 2000 to 2020. The WMC model's output takes the form of a state that is represented by the interval that contains the expected morbidity. In the first stage, the simulation results of the WMC model are analyzed, with an emphasis on the number of states and the biggest step in the Markov chain. In this research, the maximum step and the number of states were combined in 10 different ways. The analysis's study revealed that the maximum step and the number of states had no impact on the predictive value of the morbidity rate. The WMC model's projections for the morbidity rate in 2021 are presented in the second stage. These forecasts are then verified by the predictions from the Simple Exponential Smoothing (SES) approach, and it is concluded that these predictions are fairly consistent.
