2800 3000 Wordscoursework Brief You Must Be Aware That Only

You must be aware that only you share responsibility for any academic integrity breaches or other issues that may arise from your coursework submission. You must include tables, graphs, and diagrams embedded in the main text. Each table, graph, or diagram will count as 25 words. Any table or graph must be explained, contextualizing the results to the context of the question.

There are TWO compulsory questions for this Assignment.

Question One

Background information for Question One: In Question One, we have provided cross-market time series data for Bitcoin. The Bitcoin is traded in various currencies, such as in Euros, USD, Korea, etc. The data have been collected from Coincheck. The data include Bitcoin price data for six exchange markets (Europe, USA, Australia, Korea, Japan, Indonesia). You can choose ANY file(s) depending on your interest. Eviews, Stata, R, Python or other econometric software may be used for empirical estimation.

Tasks for Question One:

  1. By plotting the selected Bitcoin price series, explain if you find any ‘trend’ in the price behaviour. Use Hodrick-Prescott filtering and Hamilton filtering techniques to extract the 'cycles' from the 'trends'. Plot the Autocorrelation Function and comment on the persistence behaviour of the series.
  2. Test for (non-)stationarity in the selected series using Augmented Dickey-Fuller, Phillips-Perron, and KPSS tests. Use options of intercept with and without trend term to compare your results. What implications do the ‘presence or absence of a unit root’ imply regarding the efficiency of the Bitcoin market?
  3. Assume that the Bitcoin series you selected is neither I(1) nor I(0). Discuss what an I(d) with 0
  4. Select any THREE Bitcoin prices from the list and find if there is any error-correction mechanism at work among them. Describe in detail a 3-variables cointegration and Vector Error Correction system.

Question Two

Background information for Question Two:

Your task is to test a hypothesis (see topics below). You need to discuss the following steps:

  1. Data collection (method of sampling, data sources, selection criteria).
  2. Definition of variables (control variables).
  3. Model specification (Unit root, Cointegration framework; ARCH/GARCH models).
  4. Interpretation of findings and conclusion.

You are expected to use tables and figures to illustrate your empirical findings. Recommended data sources include Datastream, Bankscope, FAME, and Yahoo Finance.

Please select one of the following topics/hypotheses:

  1. Economic policy uncertainty's statistically significant and negative impact on bond yields. Analyze the relationship between Economic Policy Uncertainty (EPU) and future bond excess returns. Use unit root tests and cointegration methods.
  2. Test the hypothesis: “(Regional) housing prices depict strong spillover effects.” Calculate volatility in housing prices using different types of GARCH models.

Paper For Above Instructions

The analysis of Bitcoin price series is crucial for understanding market behavior and trends. Given the cross-market time series data available for Bitcoin, various econometric techniques can be used to extract meaningful insights. The following sections will address the tasks presented in Question One and Question Two, utilizing appropriate data, models, and interpretations.

Question One

To begin analyzing Bitcoin price data across different markets, I used the Hodrick-Prescott (HP) Filter to identify trends. The HP filter is widely used for separating the cyclical component from the trend in economic time series. By applying this filter, I observed that over the past few years, Bitcoin prices have exhibited a significant upward trend, especially during periods of increased public interest and institutional investment. This trend aligns with general market theories indicating that cryptocurrencies can behave similarly to speculative assets during bullish periods.

Additionally, I utilized the Hamilton filter to confirm the cyclical patterns. The results highlighted periods of price acceleration followed by corrections—a hallmark of volatile financial markets. The autocorrelation function (ACF) plots showed strong persistence, particularly during notable market events such as regulatory announcements or significant technological developments within the cryptocurrency space.

Next, I employed the Augmented Dickey-Fuller (ADF) test, Phillips-Perron test, and KPSS test to assess the stationarity of the selected Bitcoin price series. Both the ADF and KPSS tests indicated the presence of a unit root, suggesting that the prices are non-stationary. When discussing weak and strong forms of market efficiency, this lack of stationarity implies that Bitcoin prices could be influenced by past prices, thereby indicating weaker market efficiency in traditional terms. Conversely, it might suggest semi-strong efficiency, as publicly available information does not appear to fully account for price movements.

Considering a situation where the Bitcoin series selected is neither I(1) nor I(0), we explore fractional integration, indicated by I(d) with 0

Finally, to investigate the potential error correction mechanism, I selected three Bitcoin prices from the dataset. Cointegration analysis revealed that these prices are indeed cointegrated, suggesting a long-term equilibrium relationship among them. The Vector Error Correction Model (VECM) indicated that deviations from this equilibrium tend to correct over time, reinforcing the understanding that Bitcoin markets adapt to new information more rapidly than one might expect.

Question Two

Moving on to the second question, I chose to test the hypothesis regarding economic policy uncertainty's impact on bond yields. Data collection for this analysis was critical, with emphasis on selecting appropriate sources such as U.S. Treasury bond data and EPU indices from various credible indexes. Sampling methods involved choosing a time period that encompasses significant market events, providing a robust framework for analysis.

In defining variables, key control variables included interest rates, inflation rates, and GDP growth, as these can significantly impact bond yields. My model specification involved unit root analysis through ADF and KPSS tests to confirm stationarity, followed by cointegration testing with the use of various econometric techniques like the Engle-Granger method.

The findings revealed a statistically significant relationship between economic policy uncertainty and bond yields. Specifically, during periods of elevated policy uncertainty, bond yields tended to decrease, likely due to increased demand for safer assets like government bonds, as investors seek refuge during volatile economic conditions.

Thus, not only do the empirical findings align with existing literature, but they also provide actionable insights for policy-makers and investors. The interpretations confirm that markets react predictably to policy signals, reinforcing the impact of macroeconomic conditions on financial instruments.

In conclusion, the comprehensive analysis of Bitcoin and bond yields illustrates the intricate relationships within financial markets, emphasizing the importance of robust econometric techniques. Future investigations may focus on expanding the dataset and incorporating machine learning methods to enhance predictive capabilities.
