Abstract

This study aims to reveal the extent of macroeconomic instability, which has the characteristics of a financial crisis and inflation. To test the hypothesis, researchers use fixed effects and random effects estimators to assess the presence of individual and temporal effects. Macroeconomic fundamentals, especially the risk of devaluation and a drop in economic activity can be seen as early warning signs of banks becoming less solvent. They also play a big role in explaining how deposits changed during the crisis. Our findings highlight the unique features of the convertible monetary regime, reinforcing the belief that debtors will enjoy permanent protection against devaluation risks. This perception encourages the dollarization of bank portfolios, thereby increasing the financial system's solvency risks. There is also evidence that the regulatory framework in this area is weak when it comes to the financial system's exposure to devaluation risks and public debt risks. This is especially true when it comes to an institutional framework that makes it hard for government funding to be changed into other currencies. We find that inflation is a very persistent process during periods of high inflation. However, with the decline in inflation after the implementation of the convertibility regime, its persistence reduced significantly. The results show that non-rational persistence is currently not very high, suggesting that the costs of designing the economy should not be either. We find that univariate models tend to perform better over very short horizons. The results suggest that there may be advantages to using a combination of different models, provided they are informative about the relationship between inflation and its short- and long-run determinants.

Abstract

This research aims to analyze income inequality and subjective welfare in a region. This study uses microdata from household surveys to calculate income inequality. We conducted this survey using an identical questionnaire with a sample of adults. The sample size is around 100. One of the main findings of this study is that regions that were traditionally considered to have greater inequality no longer have this attribute when compared to regional and global levels. This reflects a shift in the pattern of inequality in the region. A positive correlation was also found between income inequality and subjective well-being, as well as a curve when comparing subjective well-being inequality with products. These results suggest that there is a complex relationship between these factors in the context of inequality. However, when compared with the level of subjective well-being, there is a very negative relationship, which may indicate an individual's preference to live in areas that are more egalitarian in terms of well-being. This indicates that subjective well-being perceptions are also influenced by factors other than income, such as access to facilities and services. Although these results are interesting, it is important to remember that this study has problems and limitations in terms of the survey and methods used. Therefore, these results should be interpreted with caution and can serve as a basis for further research to understand more deeply the relationship between income inequality, subjective well-being, and other factors that influence perceived well-being.

Abstract

This research aims to understand and describe the behavior of a group of people who consume craft beverages. We will conduct this research using a type of ethnography known as particularistic ethnography. We will use qualitative research techniques like group meetings and in-depth interviews in this research. In the analysis of men's mind maps, the words friends and food appeared most frequently, indicating that men associate drinking craft beverages with strong relationships with friends and consume them in a relaxed and informal setting, often accompanied by food consumption. On the other hand, in the analysis of women's mind maps, although the compartments are similar to men's with the dominance of the word friend, the difference lies in the consistent use of pink in writing words, especially friendship. This suggests that women associate craft beverages with camaraderie with friends in a fun, relaxed atmosphere. Both men and women equated craft beverages with femininity. They describe these characteristics as being informal, wearing jeans, having a friendly attitude, and having positive energy. This suggests that craft beverage typically evokes an informal and relaxed atmosphere, lacking the structure of other products or services. This shows that consumers see craft beverages as fun, warm, and suitable for enjoying in a relaxed, friendly atmosphere. Craft beverages and social interactions between friends have a strong connection, and drinking craft beverages occurs in a relaxed and laughter-filled atmosphere.
