Using a threshold-error-correction model for non-ferrous metals spot-futures prices the study reports evidence that equilibrium adjustment is quicker when the futures price exceeds the spot price.
It indicates that the impact of the copper future price in SHFE on the global market has been increasing in recent years
Taking price data for ten metals – six industrial (aluminium, copper, lead, nickel, tin and zinc) and four precious (gold, silver, palladium and platinum) – widely traded on the London Metal Exchange for the period 2000 to 2015, our empirical evidence indicates that large downward and upward oil price movements had spillover effects on all these metals both before and after the outbreak of the global financial crisis.

We find that both industrial activity and world GDP correlate with total scrap supply, with limited dependence on copper price.
Accordingly, the estimation results conducted in the cointegration framework over the period 1994q1–2012q4 reveal the existence of a long-run equilibrium relationship between the real copper price and real kwacha/US$ exchange rate.
Copper price shocks significantly affect China's PPI over the short and medium terms and the aggregate demand shock displays the most.
Second, it is shown that a partially integrated copper producer may find rationing profitable as a means of partially achieving the effects of price discrimination given that price discrimination itself is infeasible.
These empirical results signify the importance of closely monitoring underlying developments in the copper price in order to design appropriate policy response to ensure that impulses to the copper price do not undermine the external competitiveness of the economy.
Our results indicate that the impact of international copper price shocks on China's PPI is time-varying.
The results reveal that, financial speculation accentuated copper price moves during the last decade.

How does inflation affect the physiological needs of individuals and communities in the philippines?
5 answers
In the Philippines, inflation has a significant impact on the physiological needs of individuals and communities. Rising prices, as a result of inflation, can lead to increased poverty levels, particularly affecting the poor and ultra-poor segments of society. The vulnerability to food inflation is higher among poor agricultural households, leading to a greater impact on poverty severity and the poverty gap for these groups. Additionally, inflation can result in a stagflationary effect, where monetary and credit contraction increases the cost of financing working capital needs, potentially leading to a costly recession before price inflation can be controlled. Overall, inflation in the Philippines can exacerbate poverty levels and create challenges in meeting the basic physiological needs of the population.
How does political stability impact economic growth and development?
5 answers
Political stability plays a crucial role in influencing economic growth and development. Studies have shown that political stability is significantly linked to economic growth, with a focus on factors like inflation, government expenditures, and regulatory quality. Countries with stable political regimes tend to experience higher long-term growth rates, emphasizing the importance of maintaining political stability for sustained economic development. The case of Singapore highlights how consistent political stability contributes to economic success through effective planning and long-term growth strategies. Conversely, political and economic instability can lead to negative impacts on economic growth, as seen in Yemen where instability contributed to deteriorating growth rates and other economic challenges. Overall, political stability is a fundamental pillar for fostering economic growth and prosperity in any society.
How does the global refugee crisis affect education for refugee children?
5 answers
The global refugee crisis significantly impacts education for refugee children by subjecting them to structural disadvantages, limited resources, and challenges in accessing quality education. Refugee learners often face protracted displacement, lack of global commitment to education, and insufficient support for their transnational lives. The lack of legislative frameworks for refugee status determination hinders educational support efforts, preventing a comprehensive evaluation of factors affecting migration and integration. Studies reveal that refugee children in camps like Bambasi lack adequate facilities, qualified teachers, and face language barriers, emphasizing the urgent need to protect their right to education. Additionally, teachers at refugee learning centers face demands like inadequate facilities and diverse student needs, requiring support to provide quality education. Efforts like accelerated education programs have shown progress in academic skills but face challenges due to high attrition rates.
What is the refugee crisis for education?
5 answers
The refugee crisis for education encompasses various challenges faced by refugees in accessing quality and adequate education in host countries. This crisis is shaped by broader dynamics of educational privatization, where private actors are increasingly involved in providing education to refugees alongside governments and civil society. Refugee learners often encounter structural disadvantages due to forces of globalization, restrictive mobility regimes, and geopolitical agendas, leading to limited educational opportunities. Refugee education aims to facilitate social transformation, mutual understanding between refugees and host communities, and trauma recovery through specialized curricula designed based on different protection frameworks. The lack of comprehensive frameworks and vulnerabilities such as inadequate educational facilities, social challenges, and psychological needs further exacerbate the refugee educational crisis.
Can sentiment analysis of social media data accurately predict changes in Bitcoin value?
5 answers
Sentiment analysis of social media data, particularly Twitter, has shown promise in predicting changes in Bitcoin value. Various studies have utilized sentiment analysis alongside machine learning techniques to forecast cryptocurrency prices based on social media sentiment and historical data. The use of advanced models like Bidirectional Encoder Representations from Transformers (BERT) and Gated Recurrent Unit (GRU) has resulted in accurate sentiment predictions with low Mean Absolute Percentage Error rates. Additionally, the integration of sentiment-related measures with price volatility has shown varying prediction accuracies across different cryptocurrencies and sentiment analysis approaches. Therefore, while sentiment analysis of social media data can provide valuable insights into Bitcoin price changes, the accuracy of predictions may depend on the specific cryptocurrency being analyzed and the sentiment analysis methodology employed.

What factors should be considered when conducting a property analysis for industrial buildings?
5 answers
When conducting a property analysis for industrial buildings, several key factors should be considered. These include location, property characteristics, economy, government intervention, industrial agglomeration, transport and infrastructure, technology level, variable climate, environmental contamination. Additionally, it is crucial to assess the risks associated with financing industrial properties, as it can impact both the market value and overall collateral of the property. Energy performance and thermal comfort conditions are vital aspects to evaluate, with considerations for building envelope retrofitting, insulation, ventilation, and energy consumption reduction strategies. Furthermore, sustainable development practices, environmental management systems, and green criteria such as waste management, energy consumption, and materials usage play a significant role in analyzing the environmental effects of industrial buildings.
