Money is a tool that can be used in exchanging goods and services in a certain area. Increasing and decreasing in the money supply excessively can have a negative impact on the economy. For this reason, in order to maintain financial system stability in Indonesia, it is necessary to conduct an analysis of the data on the amount of outflows of rupiah currency at each Bank Indonesia office. In this study, a relationship analysis will be carried out between the eastern region of Indonesia and the amount of outflows of Bank Indonesia banknotes during the 2016-2018 period using circular regression analysis. The results showed that 83.03% of the variation in the amount of outflows of BI banknotes could be explained by the circular regression model that was formed. In addition, in the process of forecasting data on the amount of outflows of BI banknotes in the eastern region of Indonesia for the 2019-2020 period, the time series forecasting method is used which is based on the use of analysis of the relationship pattern between the estimated variables and the time variable.

Abstract Innovation plays an important role in achieving green-growth economic development in China, while the spread of haze pollution (also called smog) inhibits innovation activities. Using panel data on 265 cities at the prefecture level in China from 2001 to 2016, this paper investigates the relationship between haze pollution and urban innovation. The conclusions are as follows. First, haze pollution has a significant inhibitory effect on urban innovation. After we consider endogeneity, eliminate extreme values, and incorporate spatial correlation, we find that the negative impact of haze pollution on urban innovation still exists. Second, the channels through which haze pollution affects urban innovation can mainly be attributed to population density, the size of the home market, and economic activity. Third, among the different regions in China, the inhibitory effect of haze pollution on innovation is the most serious in the eastern region, followed by the central and western regions. Moreover, across diverse Chinese cities, the significant inhibitory effects of haze pollution on innovation are mainly in cities that are not provincial capitals and resource-based cities. Accordingly, efficient management of haze pollution is a critical prerequisite and effective guarantee for improving urban innovation.JEL codes: K32; O13; O31; R11

The essay looks at male gambling by investigating it as a form of resistance to the utilitarian values which lie at the base of the market logic. Here the excess is viewed as a central notion in opposition to that of utility. Far from minimising the negative impact of excessive gambling on society and individuals, this contribution attempts to go beyond an analysis based on the categories of pathology and expenditure only. Through excess, the pathological gambler unveils the symbolic and arbitrary ideology of capitalism which sees economic success as a sign of election or a choice whereby money is used not as an investment or to access to goods and services, but “wasted”.To address these issues, two complementary ethnographic methods are used: (1) a three-month ethnographic observation in 23 gambling locations in Milan’s metropolitan area; (2) 10 in-depth interviews with extreme male gamblers.The article attempts to answer the following research question: How does excess take place in male gambling practices? Risk factors for extreme gambling are analysed, with a particular focus on the relationship between gambling and masculinity. In the effort to go beyond an analysis of gambling based on the categories of pathology and expenditure only, gambling is conncetd to the notion of excess. Gambling locations as facilitators of excess are studied, and the life stories of pathological gamblers discussed. The paradoxical ambivalence of gambling practices, on the one side a form of domination of the subordinate classe, on the other an opportunity to resist through an anti-utilitarian act, are highlighted.

Abstract Correctly understanding and handling the relationship between economic development and environment protection is an eternal subject for human society. Based on the panel data of 31 provincial administrative units in China from 2000 to 2013, this study used Normalized Difference Vegetation Index (NDVI) and Night-Time Light data to characterize the effect of ecological restoration practices and economic development respectively, and made an empirical study on the impact of ecological restoration on economic development by means of trend analysis, panel regression model and sub-sample analysis. The results showed that the spatial distribution of Night-Time Light was high in the east and low in the west, and the NDVI in the northwest of the Hu Line was generally low, while the southeast was higher. During the 14 years from 2000 to 2013, the overall vegetation coverage showed an upward trend, and the area with stable night lights accounted for the largest proportion. The influence of NDVI on Night-Time Light presented an inverted U-shaped relationship, which meant that the negative influence of the former on the latter was not an inevitable result but its periodic performance. In the process of economic development, there was an optimal value of vegetation coverage. The increase in vegetation coverage had a negative impact on the economic development of the eastern region, but it was beneficial to the central and western regions. In the future, the government should strengthen protection and restoration of ecosystem, promote high-level protection of environment and high-quality development with efficient environmental and economic policies, and differentiate the relationship between development and ecology in the eastern, central and western regions.

Abstract The rapid development of China's economy and urbanization has led to the rapid deterioration of the ecological environment. This study aims to explore the relationship between provincial eco-efficiency and technological innovation in China. The DEA model is used to measure the ecological efficiency of 30 regions in China by using the data from 2007 to 2017, and different spatial econometric models were used to explore the influencing factors of ecological efficiency. The results show that in terms of ecological efficiency, the western region has the highest ecological efficiency, and the eastern region has the lowest. However, with the acceleration of urbanization, the ecological efficiency of the three regions gradually declined, and the last three regions basically remained at the same level. Based on spatial econometric analysis, the relationship between technological innovation and ecological efficiency is discussed. The results show that technological innovation has a negative impact on ecological efficiency, which confirms the existence of the environmental Kuznets Curve. In addition, environmental regulation and education level can improve ecological efficiency, while urbanization rate can reduce ecological efficiency. At the same time, spatial spillover effect plays an important role in technological innovation, environmental regulation, education level and urbanization rate in the change of regional ecological efficiency. Policy recommendations for further strengthening environmental protection and sustainable development are discussed.

This study examined the relationship between environmental regulations (ER) and green economic efficiency (GEE) based on the panel data of 30 provinces in China from 2008 to 2017. Firstly, GEE was calculated and evaluated using the super-efficiency SBM model with undesirable outputs. Secondly, the impact of ER on GEE was studied with the Tobit model. Finally, this article draws conclusions based on the above analysis and offers some suggestions for government and enterprise. The results show that the GEE of China is generally low. The GEE of the eastern region is much higher than that of the middle and western regions, with the western region performing slightly better than the middle. From west to east, there is a V shape, with high efficiency in the west and east and low efficiency in the middle. The impact of ER on GEE has the characteristics of nonlinearity and spatial heterogeneity. At the national level, as well as in the middle and western regions, the impact of ER on GEE shows an inverted U shape that first rises and then falls. ER are currently within the range conducive to the development of GEE. If the intensity of ER exceeds the critical value, they will have a negative impact on GEE. In the eastern region, the impact of ER on GEE is shown as a U shape that first falls and then rises. At present, the ER are not of sufficient intensity to contribute to the improvement of GEE. Only when the intensity of the ER exceeds the critical value will they have a positive influence on the GEE.

China has been actively taking actions to control carbon emissions and promoting development of a carbon market. However, there are many disadvantages in a carbon market, owing to various designs and policies still under trial and implementation. Adopting the multi-agents technique, we constructed a framework about national carbon market to estimate the effect of a different design of policy made on the GDP (Gross Domestic Product) and environment. In particular, national and regional abatement policies were analyzed in our study. The results showed the carbon-trading mechanism can effectively reduce carbon emissions and make a negative impact on GDP. National abatement can neither be too high nor too low for reducing carbon emissions and maintaining economic stability. For different regions, the central region was impacted the most by a carbon trading mechanism, and the east region was the opposite. Moreover, the “sweeping approach” policy should be replaced by a regional “discriminating policy” because the abatement requirement to the western region was low and to the eastern region was relatively high, which is more beneficial to China’s regional development.

The Bodo of the North Eastern region of India have their own kinship system to maintain social relationship since ancient periods. Kinship is the expression of social relationship. Kinship may be defined as connection or relationships between persons based on marriage or blood. In each and every society of the world, social relationship is considered to be the more important than the biological bond. The relationship is not socially recognized, it fall outside the realm of kinship. Since kinship is considered as universal, it plays a vital role in the socialization of individuals and the maintenance of social cohesion of the group. Thus, kinship is considered to be the study of the sum total of these relations. The kinship of the Bodo is bilateral. The kin related through the father is known as Bahagi in Bodo whereas the kin to the mother is called Kurma. The nature of social relationships, the kinship terms, kinship behaviours and prescriptive and proscriptive rules are the important themes of the present study.
