  1. Styles in business process modeling: an exploration and a model

    Pinggera, Jakob; Soffer, Pnina; Fahland, Dirk; Weidlich, Matthias; Zugal, Stefan; Weber, Barbara; Reijers, Hajo A.; Mendling, Jan
    Business process models are an important means to design, analyze, implement, and control business processes. As with every type of conceptual model, a business process model has to meet certain syntactic, semantic, and pragmatic quality requirements to be of value. For many years, such quality aspects were investigated by centering on the properties of the model artifact itself. Only recently, the process of model creation is considered as a factor that influences the resulting model's quality. Our work contributes to this stream of research and presents an explorative analysis of the process of process modeling (PPM). We report on two...

  2. Are Tax Havens Good? Implications of the Crackdown on Secrecy

    Weichenrieder, Alfons; Xu, Fangying
    The pressure on tax haven countries to engage in tax information exchange shows first effects on capital markets. Empirical research suggests that investors do react to information exchange and partially withdraw from previous secrecy jurisdictions that open up to information exchange. While some of the economic literature emphasizes possible positive effects of tax havens, the present paper argues that proponents of positive effects may have started from questionable premises, in particular when it comes to the effects that tax havens have for emerging markets like China and India.

  3. Die Volkswirtschaftslehre an der Hochschule für Welthandel, 1918-1973

    Klausinger, Hansjörg
    This contribution examines the teaching of economics at the Hochschule für Welthandel as a case study in the evolution of Austrian academic economics in the 20th century. The period considered is divided into three periods - before, under and after the NS-regime. The main focus is on the multiparadigmatic character of the discipline before WWII, on economics under the NS rule, and on the restoration and delayed integration of economics into the international mainstream after 1945. On the personal level, the teaching of economics at the Welthandel was dominated for more than three decades by Walter Heinrich and Richard Kerschagl,...

  4. Bayesian Variable Selection in Spatial Autoregressive Models

    Crespo Cuaresma, Jesus; Piribauer, Philipp
    This paper compares the performance of Bayesian variable selection approaches for spatial autoregressive models. We present two alternative approaches which can be implemented using Gibbs sampling methods in a straightforward way and allow us to deal with the problem of model uncertainty in spatial autoregressive models in a flexible and computationally efficient way. In a simulation study we show that the variable selection approaches tend to outperform existing Bayesian model averaging techniques both in terms of in-sample predictive performance and computational efficiency.

  5. Growing Together? Projecting Income Growth in Europe at the Regional Level

    Crespo Cuaresma, Jesus; Doppelhofer, Gernot; Huber, Florian; Piribauer, Philipp
    In this paper we present an econometric framework aimed at obtaining projections of income growth in Europe at the regional level. We account for model uncertainty in terms of the choice of explanatory variables, as well as the nature of the spatial spillovers of output growth and human capital investment. Building on recent advances in Bayesian model averaging, we construct projected trajectories of income and human capital simultaneously, while integrating out the effects of other covariates. This approach allows us to assess the potential contribution of future educational attainment to economic growth and income convergence among European regions over the...

  6. Games with the Total Bandwagon Property

    Honda, Jun
    We consider the class of two-player symmetric n x n games with the total bandwagon property (TBP) introduced by Kandori and Rob (1998). We show that a game has TBP if and only if the game has 2^n - 1 symmetric Nash equilibria. We extend this result to bimatrix games by introducing the generalized TBP. This sheds light on the (wrong) conjecture of Quint and Shubik (1997) that any n x n bimatrix game has at most 2^n - 1 Nash equilibria. As for an equilibrium selection criterion, I show the existence of a ½-dominant equilibrium for two subclasses of...

  7. Fiscal Rules and Twin Deficits: The Link between Fiscal and External Balances

    Badinger, Harald; Fichet de Clairfontaine, Aurélien; Reuter, Wolf Heinrich
    This paper investigates the relationship between countries' fiscal balances and current accounts with an emphasis on the role of fiscal rules. The direct effect of fiscal policy on the current account via aggregate (import) demand is potentially amplified by indirect effects, materializing through interest rate effects and inter-generational transfers that reduce savings. On the other hand, the implied positive relation between fiscal and external balances is potentially attenuated by offsetting changes in savings through Ricardian equivalence considerations. We expect this attenuation effect to be stronger in countries with more stringent fiscal rules and test this hypothesis using a panel of...
