  • Cost structure of the local telecommunications industry

    Creator:
    Gainutdinova, Olesya
    Abstract:
    Using a panel data set on the local telecommunications companies reporting to the FCC for 1988-95, this paper investigates the subadditivity of the cost function, as well as technical and allocative inefficiency of the U.S. local telephone industry. The subadditivity test on the estimated translog cost function indicates that certain...

  • Essays on parametric and nonparametric estimation of market structure and tax incidence in the U.S. brewing industry

    Creator:
    Pipoblabanan, Chayun
    Abstract:
    This dissertation addresses two main issues involving alcohol markets. In the first, we employ both parametric and nonparametric methods to analyze the market structure and estimate the degree of market power in the U.S. brewing industry. In the nonparametric case, we use the variations in the excise tax to test...

  • Helping end-user programmers help themselves : the idea garden approach

    Creator:
    Cao, Chen
    Abstract:
    End-user programmers face many barriers in programming. Research has seen many programming environments that attempted to lower or remove the barriers but despite these efforts, empirical studies continue to report barriers users face. To investigate this issue, we took a theory-informed approach. Using theories from design, creativity, and problem solving...

  • Essays in incomplete agricultural markets

    Creator:
    Cross, Robin M.
    Abstract:
    Agricultural revenues, the product of stochastic prices and yields, lead to markets which are incomplete, thereby entreating and complicating economic inquiry. The following three essays explore the incomplete nature of agricultural markets and consider the implications of incompleteness for a range of policy questions and economic tools. The first essay,...

  • Leveraging Generated Tests

    Creator:
    Alipour, Mohammad Amin
    Abstract:
    The main goal of automated test generation is to improve the reliability of a program by exposing faults to developers. To this end, testing should cover the largest possible portion of the program given a test budget (i.e., time and resources) as frequently as possible. Coverage of a program entity...

  • Eliciting informal specifications from scientific modelers for evaluation and debugging

    Creator:
    Bogart, Christopher
    Abstract:
    Professional software engineers have an arsenal of techniques such as unit testing and assertions to check their specifications, but these techniques require tools, motivation, experience and training that programmers without professional software engineering training may not have. As a result, professionals in other fields, such as scientific modelers, face greater...

  • Macroeconomic fluctuations and economic growth : the case of Korea

    Creator:
    Yoon, Tae-Yong
    Abstract:
    The thesis presents a useful and effective blend of insights about macroeconomic business fluctuations and the effects of government expenditure in economic growth in Korea. In Chapter I, I show that the joint behavior of key Korean macroeconomic variables is consistent with traditional Keynesian interpretation of macroeconomic business fluctuations by...

  • Renewal risk processes with stochastic returns on investments : a unified approach and analysis of the ruin probabilities

    Creator:
    Constantinescu, Corina D.
    Abstract:
    This thesis considers one of the classical problems in the actuarial mathematics literature, the decay of the probability of ruin in the collective risk model. The claim number process N(t) is assumed to be a renewal process, the resulting model being referred as the Sparre Andersen risk model. The inter-claim...
