A bstract Economic sociology furthers a healthy alternative to price-theory–oriented economics as it sets out to remedy the invisibility of the market within the latter. There is, however, no doubt that such a market-oriented sociology is still in its infancy, given among other issues its inability to shoulder market change. The void thus recognized opens up the potential for a market idea with both social and dynamic properties. There is good reason to believe that such an endeavor would benefit from the constructive blending of economic sociology and Austrian economics. This paper argues that such a "socio-Austrian" connection is in the position to enrich the socioeconomic discourse in general and its market conception in particular. 相似文献

This study develops a model for wildlifemigrating seasonally between a conservationarea and a neighbouring area. When beingoutside the conservation area, harvesting takesplace by a group of small-scale farmers. Thelocal people have two motives for harvesting;to get rid of ``problem' animals as roamingwildlife destroys crops and agriculturalproducts, and hunting for meat and trophies.Depending on the specification of the propertyrights, the harvesting is legal or illegal. Itis demonstrated that it is far from clear whichof the two property rights regimes that givesthe highest wildlife abundance. Hence, contraryto what is argued for in the literature,handing the property rights over to the localpeople means not automatically more wildlifeand a more ``sustainable' resource utilization.The reason lies in the nuisance motive forharvesting. The exploitation under the twodifferent property rights regimes areillustrated by numerical calculations with datathat fits reasonable well with the exploitationof the wildebeest population in theSerengeti-Mara ecosystem. 相似文献

We evaluate the empirical performance of forward‐looking models for inflation dynamics in a small open economy. Using likelihood‐based testing procedures, we find that the exact formulation is at odds with Norwegian data. Moreover, some of the parameters in the model are not well identified. We also find that the inexact formulation is not rejected statistically using a test based on a minimum distance method. However, confidence regions also reveal an identification problem with this model. Instead, we find a well‐specified backward‐looking model with imperfect competition underlying the price setting, which is a model that outperforms an alternative forward‐looking model in‐sample. The backward‐looking model also forecasts somewhat better than the alternative forward‐looking model, during and after the recent financial crisis. 相似文献

A Comparison of Sequential and Information‐based Methods for Determining the Co‐integration Rank in Heteroskedastic VAR Models 下载免费PDF全文

In this article, we investigate the behaviour of a number of methods for estimating the co‐integration rank in VAR systems characterized by heteroskedastic innovation processes. In particular, we compare the efficacy of the most widely used information criteria, such as Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) , with the commonly used sequential approach of Johansen [Likelihood‐based Inference in Cointegrated Vector Autoregressive Models (1996)] based around the use of either asymptotic or wild bootstrap‐based likelihood ratio type tests. Complementing recent work done for the latter in Cavaliere, Rahbek and Taylor [Econometric Reviews (2014) forthcoming], we establish the asymptotic properties of the procedures based on information criteria in the presence of heteroskedasticity (conditional or unconditional) of a quite general and unknown form. The relative finite‐sample properties of the different methods are investigated by means of a Monte Carlo simulation study. For the simulation DGPs considered in the analysis, we find that the BIC‐based procedure and the bootstrap sequential test procedure deliver the best overall performance in terms of their frequency of selecting the correct co‐integration rank across different values of the co‐integration rank, sample size, stationary dynamics and models of heteroskedasticity. Of these, the wild bootstrap procedure is perhaps the more reliable overall as it avoids a significant tendency seen in the BIC‐based method to over‐estimate the co‐integration rank in relatively small sample sizes. 相似文献

Recent studies offer evidence of reduced fiscal procyclicality to commodity price changes in resource‐rich countries—a feature commonly attributed to the adoption of fiscal policy rules. We revisit this issue and find that, by controlling for global activity shocks while allowing for time‐varying changes in both fiscal policy and the volatility of shocks, this finding does not hold. To show this we develop a time‐varying dynamic factor model, allowing for a multiple of shocks, stochastic volatility and time‐varying parameters, and estimate it on data for Norway, whose handling of resource wealth is often cited as exemplary. 相似文献

This paper describes an extension of Duchin's world trade model to include the explicit representation of transportation costs, permitting the endogenous determination of bilateral trade flows and region-specific prices. The original model is a linear program that, based on comparative advantage and the minimization of factor use, determines regional production and trade flows as well as world prices and scarcity rents for m regions, n good, and k factors. The new world trade model with bilateral trade achieves its objectives by introducing transportation services and geographically dependent transportation requirements for each traded good and each pair of potential trade partners. The formulation of this model and its major properties are presented, and results from a preliminary analysis with 11 regions, eight goods, four transportation sectors, and six factors of production are reported and compared with corresponding results from the world trade model. On the basis of this comparison, we conclude that transportation costs have little impact on a region's total imports or exports of a given commodity. 相似文献

This paper shows that important insights can be lost when assessing the relative performance of balancing methods solely based on individual optima. This is demonstrated through a multi-objective assessment. A trade-off curve between RAS and sign-preserving absolute differences (SPAD) is obtained based on the 60×60 Norwegian 2001 input–output table. The trade-off curve takes on a form that is close to a step function. This demonstrates that the solution surface around the RAS and SPAD optimums are very flat. Solutions can be identified that improve on the other objective or measure with little or marginal cost to the original objective function. Motivation for the assessment is provided, the technique applied is presented and the implications of the findings are discussed in an input–output and industrial ecology context. 相似文献

Research on projects is not only an immature field of research, but it is also insubstantial when it comes to understanding what occurs in projects. This article contributes to making project management research matter to the academic as well as to the practitioner by developing a project‐as‐practice approach, in alignment with the ongoing debate in social science research. The article outlines a framework and argues that there are two major challenges to the researcher and also suggests how these challenges can be met. Underlying notions of the practice approach are outlined to ensure a development of the project‐as‐practice approach that makes project management research matter! 相似文献
