Master of Agribusiness / Department of Agricultural Economics / Vincent Amanor-Boadu / Despite the dependence of more than three-quarters of a million households depending on cocoa for their living in Ghana, the production segment of the cocoa industry is fraught with significant challenges manifesting as low farm productivity. Various intervention programs to help farmers improve productivity at the farm level have been used over the past few decades. One of such programs is the Cocoa Abrabopa Program (CAA), which uses an integrated approach where farmers are supplied inputs made up of fertilizer, pesticides and fungicides as well as provided training and extension support services. The inputs are provided on credit and the producers repay the cost of these inputs upon selling their crop. This study sought to assess the results of the CAA in enhancing the net profits of its members over time. It used survey data collected over five years from members of the CAA program. The study used an econometric model to evaluate the demographic and production characteristics of CAA members on their net profits. The results show that male members in the CAA program had higher net profits that their female counterparts, about GHS 237.32 more. For every year increase in the member’s age, the net income increased by GHS 6.46, which was statistically significant at the 10 percent level. The crux of the study – the effectiveness of the CAA program in enhancing performance – was supported by the results. Participants who were two years in the program posted GHS 591.13 more net profit than those who were in their first year. Those who were three year and four or more years posted respectively GHS 1,211.04 and GHS 18,752.29 than those in the first year. All these were statistically significant at the 1 percent level. Thus, the CAA program is producing what it is expected to produce – enhancing the net profits of its members and doing so in higher levels with the duration of membership. The study also found that having a bank account produced a higher effect on net profits than being male, posting GHS 296.13 more net profit than not having a bank account. The econometric model specified and estimated was significant and the variability in all the independent variables in the model explained about 46 percent of the variability in net profits. The study recommends that the CAA program incorporates helping all its members open bank accounts as part of its offerings. It also recommends working with policymakers and community leaders across its operational areas to encourage investments in the education of females and elimination of the tenural rights discrimination that frequently confronts females in agriculture. It also recommends that an increased effort be made to expand membership of the CAA program to all cocoa producers in Western South because of the significant benefit of the yield effect of the region on net profit of CAA members in the region.

Master of Agribusiness / Department of Agricultural Economics / Keith Harris / Inefficiencies in a warehouse that operates multiple zones can create bottlenecks in the order fulfillment process. This study’s focuses on the exploration of potential bottlenecks in an agricultural aftermarket company’s order fulfillment process and its multi-zone warehouse. Order fulfillment includes stages of order processing, SKU picking and staging from the conveyor zone and the “H” zone, and the final packaging and shipping of the order within the Truck Freight Department. A review of the company’s EOP program, and the effects of the program, provides additional insight into our understanding of bottlenecks within a dynamic the system. In doing so, the research will extend the existing knowledge on warehouse management with multiple zones. The conclusion of this paper offers solutions that will alleviate the bottlenecks and improve the overall efficiency of the order fulfillment process within a multi-zone warehouse.

Master of Agribusiness / Department of Agricultural Economics / John A. Fox / The cost of wheat is the largest input cost for a flour mill, and as a result, profitability in wheat flour milling is determined in large part by milling efficiency – i.e., the amount of flour extracted per unit of wheat milled. In this project the objective was to quantify the influence of several measurable variables on flour mill efficiency. Data was collected from two commercial milling units of similar size. Linear regression was then used to estimate the relationship between flour yield and variables measuring grain characteristics and environmental factors. The analysis suggests that increasing ambient temperature and the occurrence of downtime both have a significant negative effect on flour yield. A significant difference in flour yield efficiency was also found between the two mills.

Master of Arts / Department of Economics / Dennis L. Weisman / The Internet is a network that consists of content providers and users connected to each other through the communication lines managed by network providers. Network neutrality rules are designed to protect independent content providers from unjust discrimination by network providers. This report explores the economic rationale for net neutrality rules, how the regulation should be enforced, and its potential effects on competition. The report finds that net neutrality encourages competition among content providers by subsidizing content provider access but concentrates the market for network providers by forcing network providers to compete primarily through price competition. It considers this to be a beneficial arrangement for economic growth, but observes that there is a potential for all sides of the market to be subsidized by advertiser fees. It also shows that despite the Federal Communications Commission's heavy involvement with network neutrality rules, these rules are actually based in a long history of antitrust regulation. It concludes, however, that the current regulatory environment is sufficient for enforcing net neutrality rules.

Master of Agribusiness / Department of Agricultural Economics / Arlo Biere / The purpose of the research reported in the thesis, here, is to quantify new value added possible in flour milling with the use of the SDmatic monitor, produced and sold by Chopin Technologies SAS. As an employee of Chopin, part of my responsibility is to market the SDmatic. The SDmatic was designed and is marketed to improve flour quality by providing automatic monitoring of starch damage in flour—damaged starch affects dough characteristics, which affects baking quality and the ideal damaged starch differs by type of bakery product. While the SDmatic is so marketed, Chopin, now, realizes that SDmatic might also benefit a flour miller by increasing operational efficiency of the mill, specifically by reducing the electrical energy used in milling. If that can be done, it would improve mill profitability, reduce energy demand and, thus, reduce the pressure on the climate and environment from energy production. To address that possibility, the thesis research studied the relationship between energy usage and damaged starch in the flour and, then, estimated the cost savings possible by using the SDmatic to mill flour to specifications most efficiently. Finally, those results were used to estimate the return on investment in the SDmatic from improved mill efficiency, alone. The research shows improvement in energy efficiency is definitely possible with better management and targeting of the level of starch damage in flour production. Such improved management is possible, today, because SDmatic dramatically reduces the difficulty and time required to measure damaged starch. Such monitoring has not been done in the past because of the cost and time involved with prior methods. SDmatic makes that possible and cost effective, now.

Thesis advisor: Zhijie Xiao / This paper attempts to deliver a side-by-side examination of the similarities and differences between the economies of East Asia (Singapore, Taiwan, Hong Kong, Korea Republic, Thailand, Malaysia, Indonesia, and the Philippines) and China. After the devastating 1997 Crisis, many investing eyes have turned to China as the next Asian growth engine. China has been opening its economy to foreign investors and its accession into the World Trade Organization will push for increased transparency and efficiency. The paper discusses the internal and external forces that drove the economies, with focused attention on its financial systems, using pre-crisis data. With foreign banks allowed entry into China by the end of 2006, its financial system will be an important component in economic longevity. Lastly, the question of whether or not China is vulnerable to a crisis is assessed based on the same factors that caused it in East Asia. / Thesis (BA) — Boston College, 2006. / Submitted to: Boston College.

According to the U.S. Small Business Association, the failure rates for small businesses in 2014 were as high as 50% to 80% within the first 5 years of establishment. The purpose for this multiple case study was to explore the strategies that small business owners have used to sustain their businesses beyond 5 years. Guided by entrepreneurship theory as the conceptual framework, and a purposive sampling method, this qualitative case study used semistructured interviews with 3 successful, small, ethnic grocery business owners in Anchorage, AK to better understand small business strategies for survival. Member checking and triangulation with field notes, interview data, business websites, customer comments, and government documents helped ensure theoretical saturation and trustworthiness of interpretations. Using pre-coded themes for the data analysis, the 8 themes from this study were entrepreneur characteristics, education and management skills, financial planning, marketing strategies and competitive advantages, social networks and human relationships, technology and innovation, government supports and social responsibility, and motivational influence. Two key results indicated the strategies needed for small business owners were entrepreneur management skills and government support for small businesses. These findings may influence positive social change by improving small business owner competence and sustainability, rising higher business incomes, providing a better quality of life to employees and their communities welfare benefiting the entire U.S. economy.

Empirical and theoretical topics in applied microeconomics are discussed in this dissertation. The first essay identifies and measures managerial advantages from access to high-quality deals in venture capital investments. The underlying social network of Harvard Business School MBA venture capitalists and entrepreneurs is used to proxy availability of deal access. Random section assignment of HBS MBA graduates provides a key exogenous variation for identification. Being socially connected to peer venture capital firms and private equity seeking startups leads to more deal flow, larger asset under management and better performance in the inaugural funds of HBS-executive run venture capital firms. The second essay presents a two-stage model of competing ad auctions. Search engines attract users via Cournot-style competition. Meanwhile, each advertiser must pay a participation cost to use each ad platform. Advertiser entry strategies using symmetric Bayes-Nash equilibrium that lead to the Vickrey-Clarke-Groves outcome of the ad auctions are derived. Consistent with the model predictions, empirical evidence shows that multi-homing advertisers are larger than single-homing advertisers. Comparative statics on consumer choice parameters, quality, and user welfare are used to analyze the prospect of joining auctions to mitigate participation costs. The analysis provides conditions when such joins do and do not increase welfare. The third essay develops and computes a dynamic model of search in internet advertising. Micro-level browsing data from Microsoft's Bing.com (formerly known as Live.com) is used for structural estimations. The model predicts that users do not click on any ad with weak signals due to accumulating search cost and monotonicity of the value function. Rational search reveals a cascading pattern: the user clicks on a sufficiently high, highest-signal ad first, then moves on to the ad with the next highest conditionally expected probability of match once his assessment on the current ad degrades over time. The user exits when maximum assessment of likelihood of match over all ads is below a threshold value. The essay provides a novel approach to understanding rational herding behavior when product quality is only partially unraveled.
