Master of Science / Department of Agricultural Economics / Benjamin B. Schwab / Khat, a lucrative cash crop cultivated in and near the Horn of Africa, is gaining the interest of researchers around the globe. Despite its potential to provide excess income, economic opportunity, and access to technology to those who produce it, the conflicting legal status around the globe causes policy and trade disputes between countries. Research on the impact of khat production on household welfare is sparse. To address this, the purpose of this research is to determine what factors affect the decision to grow khat and subsequently determine the impact of khat production on labor, income, education expenditure, and food security. Data was extracted from a survey conducted in early 2017. A total of 365 households in the Amhara Region of Ethiopia were surveyed. We estimate the factors affecting the decision to grow khat by employing use of two logit models and one linear probability model to calculate marginal effects. We estimate the impact of khat production on labor, income, education expenditure, and food security through propensity score matching. Khat production appears to be adopted by households who are educated and apt to adopt improved technologies. These households are likely to own a donkey, own irrigation, and own more plots than a non-producing household. Practicing seed saving, conservation techniques, and growing more crops decreases the likelihood of growing khat. Regarding impacts, khat production increases on-farm male (41.8%) and female (62.1%) labor and income (41.7%), but decreases education expense (-10.7%), food consumption scores (-15.9%), and number of food shortage months (-16.2%). Overall, khat production uses more labor, generates higher incomes, and decreases food shortage months, but decreases expenditure on education and dietary diversity.

TESIS PARA OPTAR AL GRADO DE MAGÍSTER EN FINANZAS / En este estudio se analizan las variables determinantes de los cash holdings en 88 firmas chilenas excluyendo utilities y real estate cotizantes en la Bolsa de Comercio de Santiago en el periodo 2004-2014. En consecuencia, se han utilizado las variables rentabilidad, tamaño de la firma, tangibilidad de los activos, liquidez, edad de la firma, variabilidad de los activos, leverage, oportunidades de crecimiento, gasto de capital, pago de dividendos, y deuda de corto plazo sobre deuda total. En especial, también se analiza la influencia de las familias, business groups y pirámides de control. Los resultados obtenidos indican que las siguientes hipótesis derivadas de la teoría financiera son aplicables para las firmas chilenas son la teoría del pecking order, la teoría del trade off, el motivo precautorio, y las economías de escala. Además, sugieren que la estructura corporativa afecta la decisión de acumular de efectivo. Específicamente, las variables: Business groups; empresa familiar controlada por Business groups; separación de derechos de voto y derechos de flujo de caja en empresa familiar; y derechos de flujo de caja en business groups están asociadas positivamente con los cash holdings, pudiendo ser explicado porque los controladores son más conservadores con la liquidez y presentan una mayor aversión a escenarios de restricciones presupuestarias o un aumento las reservas para futuras inversiones.

Text in Afrikaans / Die primere doelstelling met hierdie studie was om 'n kritiese beskouing van die staat van kontantvloei-inligting (hierna genoem die staat) as element van finansiele verslagdoening te verskaf met die oog op die identifisering van moontlike leemtes, tekortkominge en nut wat die gebruikers van die staat ondervind. Die studie dui daarop dat alhoewel daar 'n aantal leemtes en tekortkominge in die huidige staat is, daar wei 'n behoefte aan die kant van die gebruiker na 'n staat van kontantvloei-inligting as deel van die finansiele state bestaan. Die waarde van sodanige staat is deurgaans in die literatuurstudie sowel as met die empiriese studie beklemtoon. Dit het ook in die studie na vore gekom dat die staat vir gebruikers van groot waarde is in die evaluering van solvensie en risiko in bepaalde ondernemings. Die gebruikswaarde van die staat maak dit dringend noodsaaklik dat daar onverwyld aandag aan die leemtes geskenk moet word. Verskeie aanbevelings vir 'n verbeterde staat van kontantvloei-inligting word dan ook in hierdie studie gemaak en dit sluit 'n moontlike model in. 'n Aantal aanbevelings rondom die praktiese aspekte van die gebruik van die staat word ook gemaak, omdat dit die potensiaal het om 'n onmisbare hulpmiddel vir die gebruiker te word. / The prime objective of this study was to take a critical look at the cash flow information statement (hereinafter named the statement) as an element of financial reporting. It was based on the experience of the users in view of identifying possible gaps, shortcomings and benefits. The study suggests that a definite need occurs from the users side for cash flow information as part of the financial statements. It was also evident from the study that the statement is a very important tool for the evaluation of solvency and risk. The usability of the statement necessitates that attention be given to the gaps. Several recommendations, including a possible model were made for an improvement in the statement. A number of recommendations were also made regarding practical aspects for the use of the statement, since it has the potential to be an indispensable tool for users. / Financial Accounting / M. Com.
