New development: The protective role of conservatism in public sector accounting

This article picks up a discussion in international business accounting about the appropriate definition and use of conservatism (or prudence) and calls for a similar discussion in public sector accounting. If financial reports present an overly optimistic situation, politicians might use them to justify spending public money that is not there, risking the sustainability of services and ‘borrowing’ from future generations.     

Exploring PMOs through community of practice theory

This article explores project management offices (PMOs) through community of practice theory. Preliminary results from a national health care case study are used to confirm the legitimacy of this approach. Today's knowledge‐based economy calls for mechanisms to share knowledge. The issue of making more with less is at stake in order to reuse good practices, support innovative practice, and prevent the reinvention of the wheel. Members of these communities are at the heart of the learning process. The originality of this research is that it sheds light on PMOs in a new theoretical perspective within the field of knowledge management.     

Brain Drain: A Management or a Property Problem?

Abstract . Brain drain occurs when skilled individuals leave their native countries. It is often argued that this phenomenon has strong negative effects on the countries of origin, preventing them from capitalizing on their investment in human capital formation and thus realizing a higher growth. This analysis shows that the negative consequences of brain drain have been overemphasized, mainly because of the confusion between capital and technology. It demonstrates that investments in human capital are possible and profitable in a free market. State intervention in education is responsible for the systematic misallocation of human capital in general, and for brain drain in particular.     

Orthodox Core–Heterodox Periphery? Contrasting Citation Networks of Economics Departments in Vienna

ABSTRACT

The notion of an ‘orthodox core–heterodox periphery’ structure and the extent of interdisciplinary links have been widely discussed, and partially investigated bibliometrically, within economic discourse. We extend this research by applying tools from social network analysis to citation data of three economics departments located in Vienna, two mainstream and one non-mainstream, to assess their relative citation patterns. We show that both mainstream economics departments follow the asserted core–periphery pattern and have a mono-disciplinary research focus, while the citation network of the non-mainstream department has a polycentric structure and is both more heterodox and interdisciplinary. These findings suggest that discussions about the future of heterodox economics should pay more attention to the organizational level and seek allies from other disciplines.     

A pragmatic service typology: capturing the distinctive dynamics of services in time and space

Many service classifications have provided helpful yet partial perspectives on the heterogeneity of services. This paper reconciles and integrates different earlier classifications into a new holistic typology of the service economy which is based on detailed statistical service sectors. Moreover, the paper assesses the empirical value of this taxonomy to capture the diversity of services development in time and space. A regional analysis of employment data in Germany provides evidence that knowledge intensive as well as business services follow very different sectoral and spatial dynamics than operational and consumer services. This typology yields differential insights in longitudinal and comparative regional analysis of the service economy.     

The failure of OCA analysis

Conclusion In this paper I have tried to show that OCA theory fails to advance the case for independent fiat currencies. It does so both because of its empirical irrelevance, and because of its internal inconsistencies. Therefore, from the perspective of international monetary economics, there is no theoretical justification for the present monetary organization. Rather other factors, more related to political interests than to sound economics, should be held responsible for it. It is perhaps interesting to consider the mainstream economists’ systematic reaction when they discover there is no scientific justification for a fluctuating fiat currency system. They simply throw away the whole analysis and return to “common sense” propositions. Some of them even go so far as to recognize the merits of a world currency, eventually pegged to gold, but then dishonestly dismiss the case on the basis of “beliefs,” or popular wisdom. All remaining errors are my own.     

Ein Vierteljahres-Modell des Geld- und Kreditsektors Österreichs

Summary This study presents an econometric analysis of the monetary sector of the Austrian economy. The main focus of interest lies in the money and credit markets. We specify nine behavioral equations for the money demand sector, for the commercial banks, for the credit market, and for the bonds market, respectively. Great emphasis is put on the analogous specification of theoretically related equations; these are estimated on a quarterly basis. In order to obtain unbiased estimates we use two-stage-least-squares as estimation technique. All behavioral equations are based on a partial adjustment process. We try to avoid the concept of exogenous money supply and a monetary base completely controlled by the monetary authorities; specifications based on these concepts do not stand up against examination by simultaneous estimation methods.Another important feature of the model lies in the explicit inclusion of the main instruments of monetary authorities into the analysis. We try to show possible influences of these instruments on the monetary sector by means of the model's reduced form and by means of simulation experiments. We also report some preliminary results on the transmission process which can be obtained by combination of the monetary model with a model of the real sector of the Austrian economy. In order to evaluate the forecasting properties of the model we calculate ex post and ex ante forecast errors. In general, the results of this test are satisfactory.

From constrained optimization to constrained dynamics: extending analogies between economics and mechanics

Economic equilibrium models have been inspired by analogies to stationary states in classical mechanics. To extend these mathematical analogies from constrained optimization to constrained dynamics, we formalize economic (constraint) forces and economic power in analogy to physical (constraint) forces and the reciprocal value of mass. Agents employ forces to change economic variables according to their desire and their power to assert their interest. These ex-ante forces are completed by constraint forces from unanticipated system constraints to yield the ex-post dynamics. The differential-algebraic equation framework seeks to overcome some restrictions inherent to the optimization approach and to provide an out-of-equilibrium foundation for general equilibrium models. We transform a static Edgeworth box exchange model into a dynamic model with procedural rationality (gradient climbing) and slow price adaptation, and discuss advantages, caveats, and possible extensions of the modeling framework.

     

The Invisible Side of Political Parties: The Case of the PCdoB

The young Latin American democracies have been structuring their political parties for day-to-day management. In this context, it is important to understand how such structures could be affected by the so-called invisible side of organizations, which are composed of networks of relationships between elected politicians and then relationships between these and external militant groups, which can greatly influence the candidates’ performance and the very dynamics of the party. This article seeks to unravel some of these dimensions. We select for analysis the case of the PCdoB (Communist Party of Brazil), in the Metropolitan Region of Belo Horizonte, state of Minas Gerais, Brazil. The results show the nature of the embeddedness of these actors in the political system, highlighting weaknesses and possibilities.
