Carl Menger and the network theory of money

Carl Menger has occasionally been cited as a forerunner to the network theory of money. This article analyses Carl Menger's monetary theory and evaluates whether he was aware of the network characteristic of money from a retrospective angle. The result is mixed. Menger is one of the first to discuss the marketability and liquidity of an asset, which in German he denotes Absatzfähigkeit. This concept has a strong connection with the network aspect of a commodity. However, he is not distinct enough in his analysis and there is a lack of depth in his understanding.     

Robust Taylor rules under heterogeneity in currency trade

It is demonstrated in this paper that the exchange rate should be included in the Taylor rule when there is heterogeneity in currency trade to have a determinate and least squares learnable rational expectations equilibrium that also is desirable in an inflation rate targeting regime. Moreover, for certain Taylor rule parameterizations, these properties of the interest rate rule are robust against the degree of technical trading in currency trading.     

Finnish GNP-series 1954/I–1990/IV: Small shock persistance or trend stationarity? Some evidence with variance ratio estimates

The “shock persistance” of Finnish adjusted quarterly real GNP series in logarithms from 1954/QI to 1990/QIV is analyzed using variance ratio estimators. The results indicate that the random walk component of the series is not big. The small sample properties of variance ratio estimators are studied using empirical distribution derived from simulations. The persistence measures calculated via the ARIMA modelling of the lnGNP_t series are biased upwards. The sampling properties show that the simple random walk model is not an alternative model for the lnGNP. A trend stationary alternative, an AR(2) process, gives almost the same “shock persistence” measures as the assumed unit root processes.     

Long-run relationships between labor and capital: Indirect evidence on the elasticity of substitution

This paper proposes an indirect method for making empirical inference on the elasticity of substitution between capital and labor. The idea is that estimates of the elasticity may be retrievable from theory derived behavioral equations, by conducting comparative statics with respect to this parameter. This approach is readily applicable to more realistic models than those which are commonly used to derive estimates of the substitution elasticity. It is demonstrated that the conventional approach does not yield sensible estimates on quarterly Finnish manufacturing data. By applying the indirect method, a long-run empirical relationship is found that is consistent with an elasticity of substitution below one.     

Cognitive ability and scale bias in the contingent valuation method

This study investigates whether or not the scale bias found in contingent valuation (CVM) studies on mortality risk reductions is a result of cognitive constraints among respondents. Scale bias refers to insensitivity and non-near-proportionality of the respondents’ willingness to pay (WTP) to the size of the risk reduction. Two hundred Swedish students participated in an experiment in which their cognitive ability was tested before they took part in a CVM-study asking them about their WTP to reduce bus-mortality risk. The results imply that WTP answers from respondents with a higher cognitive ability are less flawed by scale bias.     

System estimates of potential output and the NAIRU

This paper proposes a new approach for estimating potential output and the NAIRU. The methodology models these key unobservable economic variables as latent stochastic trends within a trivariate system of observables comprising information on unemployment, GDP, and inflation. Identification is achieved through the use of a standard version of Okun's law and a Phillips curve. The performance of the procedure is investigated using Swedish quarterly data covering the time period 1970:1–1996:3. First version received: June 1997/final version received: September 1998     

Analyzing operational real options in metal mining investments with a system dynamic model

This article presents a detailed system dynamic (SD) model of a metal mining investment that is usable in ex-ante profitability and operations management analysis. We show how the SD model can be used to analyze the profitability effect of three operational real options: the option to temporarily close production, the option to abandon production, and the option to increase production through cutoff grade change. The SD model allows for intuitive modeling of the multiple interactive real options and arriving at results that are difficult, or impossible, to reach with commonly used spreadsheet software. We also analyze the effect of mining project debt ratio to the project value and show that correctly choosing the debt ratio affects project profitability. The effect on the project value of using three different future metal price scenarios with two different stochastic processes is illustrated to highlight the importance of correct process selection in modeling future metal price paths. A realistic case of a high-cost nickel (Ni) metal mine is used as a basis for the presented numerical illustration of the model.     

Effects of performance measurement system inconsistency on managers’ role clarity and well-being

In this paper we explore the impact of PMS inconsistency on managerial role clarity and well-being. In addition, we investigate if problems with PMS inconsistency can be dealt with by convincing superiors to loosen their control reactions to variances, giving managers job autonomy and providing managers with support from superiors, peers and staff functions. Based on survey responses from 799 managers in one public sector organization and 187 managers in one private sector organization we conclude that PMS inconsistency has negative effects on managers’ role clarity and well-being. This situation does not improve if superiors practice loose control; on the contrary, it seems to make managers’ work situation worse. Job autonomy and support appear to be better coping methods since they have direct positive impacts on managers’ role clarity and well-being that counteracts the negative effects of PMS inconsistency.
