Effect of Sentiment on Bitcoin Price Formation

By Brian Perry-Carrera

With the recent growth in the investment of cryptocurrencies, such as bitcoin, it has become increasingly relevant to understand what drives price formation. Given that investment in bitcoin is greatly determined by speculation, this paper seeks to find the econometric relationship between public sentiment and the price of bitcoin. After scraping over 500,000 tweets related to bitcoin, sentiment analysis was performed for each tweet and then aggregated for each day between December 1st, 2017 and December 31st, 2017. This study found that both gold futures and market volatility are negatively related to the price of bitcoin, while sentiment demonstrates a positive relationship.

Multi-Horizon Forecast Optimality Based on Related Forecast Errors

By Christopher G. MacGibbon

This thesis develops a new Multi-Horizon Moment Conditions test for evaluating multi-horizon forecast optimality. The test is based on the variances, covariances and autocovariances of optimal forecast errors that should have a non-zero relationship for multi-horizon forecasts. A simulation study is conducted to determine the test’s size and power properties. Also, the effects of combining the Multi-Horizon Moment Conditions test and the well-known Mincer-Zarnowitz and zero autocorrelation tests into one forecast optimality test are examined. Lastly, an empirical study evaluating forecast optimality for four multi-horizon forecasts made by the Survey of Professional Forecasters is included.

The Effect of Social, Cultural, and Political Values on Entrepreneurial Perceptions and Venture Creation: A Global Investigation

By Repton Salisbury

The effect of entrepreneurial activity on economic development has been researched thoroughly. New firm creation spurs economic growth by creating employment opportunities, cultivating innovation, and encouraging competition. Globally, there are countless areas that could benefit from a livelier entrepreneurial ecosystem. So how does a government or population first spur entrepreneurial activity? An entrepreneur’s perceptions are among the most powerful factors that impact the life or death of a new venture, but the determinants that influence how these perceptions first form are still largely unknown. Using survey data collected by the Global Entrepreneurship Monitor in 2010 across the United States, Japan, Switzerland, Israel, United Kingdom, Peru, Russia, Iran, and China, I conduct binary logistic regressions of individual level characteristics, social ideals, cultural norms, human development, and other environmental attributes on the most important perceptions of entrepreneurs. These perceptions have been identified by previous research as an entrepreneur’s perception of local opportunities, internal skills, and fear of failure in creating a new venture. I find that several social, cultural, and political values have a significant effect on the psychological behavior of nascent entrepreneurs.

How does being a Serial Creator affect Probability of Campaign Success on Kickstarter?

By Minn Khine

This paper seeks to address the issue of how being a serial creator impacts campaign success on Kickstarter. My hypothesis is that being a serial creator – someone who has created 2 or more projects on Kickstarter – has a positive effect on probability of campaign success but there are diminishing marginal returns to this effect. A regression analysis over a sample of over 187 thousand Kickstarter projects from its inception in 2008 until December 2014 yields the following findings, which supports my hypothesis. I found that being a serial creator does have a positive effect on campaign success but there is diminishing marginal returns to being a serial creator. Furthermore, number of updates, number of reward levels, having a video, number of backers, FB Shares, FB Friends, and Number of Projects Backed all have positive effects on campaign success. On the other hand, comments, funding goal, and duration have negative effects on campaign success. The effect of the Fed Fund Rate on campaign success is inconclusive. In terms of how project characteristics and creator characteristics affect first time creators and serial creators differently, I found that Updates, Video, FBShares, FBFriends, and Goal matter less as number of projects created increases, in other words, for serial creators who’ve gathered more project experience. On the other hand, Rewards, Backers, ProjectsBacked, Comments, and Duration matter more as number of projects created increases.

Understanding SME Finance: Determinants of Relationship Lending

By Sean Suk Hyun Choi

Much of the existing literature in small and medium-sized enterprise (SME) finance surveys the impact of borrower and lender characteristics on firms’ credit availability, and it has already been established that there is a link between strong firm-bank relationship and higher level of credit availability. In this paper, I focus on what determines the strength of relationship, measured by length and exclusivity. In particular, I was able to build an original metric to gauge the strength of relationship using the inverse value of the number of financial institution that a firm deals with. Using a set of regressions, I confirm the existing theories that size of the firm and type of ownership matters. Small firms and sole proprietorships tend to have longer and more exclusive relationships, which implies their reliance on relationship lending. Firm owner characteristics are shown to be somewhat important, in that it serves as proxies for a given firm’s creditworthiness.
