  • Cheap Talk in a New Keynesian Model

    Wesselbaum, Dennis (2016-02)

    Working or discussion paper
    University of Otago

    This paper shows that the stance of fiscal policy does have significant impact on the conduct of monetary policy in the United States. Further, we document that the implied fiscal-monetary policy interactions are subject to regime instability, using a Markov-switching model. Then, we develop a microfoundation of regime switches using a cheap talk game between central bank and government. As a case study, we simulate the effects of regime switches within an otherwise standard New Keynesian model using the cheap talk game in the state-space of our model.

  • VoIP application development using SIP protocol

    Milic, Dee; Zhou, Dong; Situ, Hailing (2008-03)

    Working or discussion paper
    University of Otago

    This aim of this project was to the explore JAIN SLEE standard 1.1 programming model and SIMPLE (Sip for Instant Messaging and Presence Leveraging Extensions) protocols, developing a Voice over Internet Protocol (VoIP) application with functions that include making a phone call, instant messaging to peers, and at the same time providing users with buddy list information of their peers. The JAIN SLEE platform RhinoSDK 2.0 (developed by OpenCloud) was to be used and an example application that is included with RhinoSDK 2.0 was to be extended. During the project the phone call functionality was scoped out of the project and the focus was set on implementing the instant messaging and presence functionality. This report describes the functions that have been implemented on the server side and client side of this VoIP application.

  • Shifting the ‘goal posts’: What is the optimal allocation of Super Rugby competition points?

    Winchester, Niven (2007-11-01)

    Working or discussion paper
    University of Otago

    Competition points are awarded in sports events to determine which participants qualify for the playoffs or to identify the champion. We use competition points to measure strength in a prediction model and choose competition points to maximise prediction accuracy. This allows us to determine the allocation of competition points that most appropriately rewards strong teams. Our analysis focuses on Super Rugby as the characteristics of this competition closely match our modelling assumptions. We find that the current allocation of competition points is not optimal and suggest an alternative. Our findings have implications for other competitions.

  • Neuro-fuzzy methods for environmental modelling

    Purvis, Martin; Kasabov, Nikola; Benwell, George L; Zhou, Qing Qing; Zhang, Feng (1998-12)

    Working or discussion paper
    University of Otago

    This paper describes combined approaches of data preparation, neural network analysis, and fuzzy inferencing techniques (which we collectively call neuro-fuzzy engineering) to the problem of environmental modelling. The overall neuro-fuzzy architecture is presented, and specific issues associated with environmental modelling are discussed. A case study that shows how these techniques can be combined is presented for illustration. We also describe our current software implementation that incorporates neuro-fuzzy analytical tools into commercially available geographical information system software.

  • Information, Institutions and Banking Sector Development in West Africa

    Demetriades, Panicos; Fielding, David (2009-01-01)

    Working or discussion paper
    University of Otago

    Using a new panel dataset for banks in eight West African countries, we explore the factors that exacerbate or alleviate excess liquidity, and the factors that promote or retard the rate of growth of banks’ assets. Loan default rates in the region are high, and variations in the rate impact on liquidity and asset growth. However, the size of this effect is very sensitive to bank age. Some types of improvement in the quality of governance reduce excess liquidity and promote asset growth. However, the impact of other types of improvement, particularly with regard to corruption, is ambiguous. We uncover evidence that provides an explanation for this ambiguity.

  • Information portrayal for decision support in dynamic intentional process environments

    Wong, B L William; Sallis, Philip; O’Hare, David (1995-07)

    Working or discussion paper
    University of Otago

    This paper reports on preliminary findings of a cognitive task analysis conducted at an ambulance despatch control center. The intense and dynamic nature of the decision making environment is first described, and the decision process modelled in an attempt to identify decision strategies used by the Communications Officers. Some information portrayal requirements stemming from one of the decision processes are then discussed, and these requirements are then translated into a proposed display solution.

  • A Model of Competition Between Multinational Firms

    Koska, Onur (2009-10-01)

    Working or discussion paper
    University of Otago

    This study focuses on the theory of how multinational firms choose their entry modes between alternative options (i.e., trade, green field investment, or acquisition). In a comprehensive model of strategic decision-making with more than one multinational firm, it delineates how a multinational firm's entry mode influences a rival multinational firm's market entry behavior and how exogenous factors (e.g., market size, firms' production cost, per-unit trade cost and fixed investment cost) affect the optimal entry modes. The main finding of the study is that competition among multinational firms substantially affects their optimal entry modes such that competition implies different entry modes compared to no competition.

  • The volatility of aid

    Fielding, David; Mavrotas, George (2005-06)

    Working or discussion paper
    University of Otago

    Issues related to the volatility of aid flows are now becoming crucial in view of their relevance to the achievement of the Millennium Development Goals. The paper examines aid volatility using data for 66 aid recipients over the period 1973-2002. We improve upon earlier work in this important area by disaggregating total aid inflows into sector and programme aid. In this way we avoid focussing on a single aggregate, unlike most previous studies on aid volatility. We also adopt a different methodology to capture aid volatility. The institutional quality of the aid recipient affects the stability of sector aid but not that of programme assistance. Moreover, more open economies, which tend to be smaller and richer, ceteris paribus, are associated with more volatile sector aid flows.

  • Asymmetries in the effects of monetary policy: the case of South Africa

    Fielding, David; Shields, Kalvinder (2005-08)

    Working or discussion paper
    University of Otago

    PPP is unlikely to hold instantaneously for all commodities across the different regions of a monetary area. It is therefore possible that monetary expansions or contractions will have different effects in different regions, if there are regional asymmetries in the monetary transmission mechanism. We estimate the size of such asymmetries across the nine provinces of South Africa over the period 1997-2005. There are large and statistically significant differences in the response of prices to monetary expansions and contractions.

  • Fair trade

    Richardson, Martin; Stähler, Frank (2007-07)

    Working or discussion paper
    University of Otago

    This paper deals with the behavior of fair trade organizations in an oligopolistic setting in which the vertically integrated fair trade firm produces a commodity which is a weak substitute for another commodity. Profit-maximizing oligopolists are vertically disintegrated and produce for both markets and the fair trade firm can charge a premium to consumers due to a “warm glow effect” that depends on the wage paid to fair trade producers. We show that trade integration will unambiguously increase the size of the fair trade firm. However, the relative size compared to oligopolists shrinks with integration. The effect of a change in substitutability between the two commodities on markets shares depends on the relative market potential. Furthermore, we show that the warm glow effect does not support an expansion of the volume of fair trade. JEL-Classification: F12.
