This paper will focus on the ambitious plan for regulation embodied in the Dominion Fisheries Act of 1868, a law passed by the Canadian federal parliament in its very first year of existence. The 1868 law was intended to bring the nation's fisheries firmly under the control of officials employed by the new federal government. The paper argues that 1868 law, which was designed to address what would today be called Tragedy of the Commons problems, was a product of the hubris identified by Hayek as "the fatal conceit." The centralized and bureaucratic approach to governing fisheries represented by the 1868 Fisheries Act did not work well because the knowledge that would have been required for successful management of fisheries was highly dispersed. Drawing on Hayek and the Bloomington School, this paper argues that the experience of Canada's fisheries sector in the generation after 1868 illustrates the problems with centralized management Common-Pool Resources. In the 1890s, the centralized approach represented by the Fisheries Act of 1868 was replaced by a more flexible and decentralized system Hayek's theory of knowledge would suggest the reversal of centralization over environmental policy in the 1890s was a positive development that helped Canadians to reconcile the goals of economic development and the protection of the environment. The Hayekian paradigm suggests that control over environmental policy should be devolved downwards to the levels of government closest to resource users.  相似文献

Unfunded pay-as-you-go state pension schemes are financially unsustainable in Europe as elsewhere. Proponents of reform argue that, by switching to a fully funded scheme that takes advantage of the high return on assets such as equities, the solvency of the state scheme could be restored at little or no financial burden to current taxpayers. We show that this is mistaken for two reasons.
First, making the transition is itself costly. Unless this cost is substantially financed by debt, it will fall on current generations, who are therefore likely to oppose the reform. Second, potentially higher returns are accompanied by significantly higher risk, which we quantify. We explain how an insurance scheme could be designed to mitigate both risk and moral hazard.  相似文献

Key sources of disagreement among economic forecasters are identified by using data on cross-sectional dispersion in forecasters’ long- and short-run predictions of macroeconomic variables. Dispersion among forecasters is highest at long horizons where private information is of limited value and lower at short forecast horizons. Moreover, differences in views persist through time. Such differences in opinion cannot be explained by differences in information sets; our results indicate they stem from heterogeneity in priors or models. Differences in opinion move countercyclically, with heterogeneity being strongest during recessions where forecasters appear to place greater weight on their prior beliefs.  相似文献

In exploring why innovators often do not profit from their innovations, researchers concentrate on innovators versus imitators and the extent to which owners of complementary assets capture profits from innovations. The literature provides scant attention to factors that sap profits from innovations. This paper argues that an innovator's positioning vis‐à‐vis customers, suppliers, complementors, and other co‐opetitors plays a critical role in the innovator's profitability. The article explores how an innovator can use new game strategies to better positioning, thus capturing rents from innovations and enabling further innovations in the future. The study examines the case of Lipitor, one of the world's best‐selling drug, to illustrate how positioning can play in a firm's ability to profit from its innovations.  相似文献

Real-world industries are composed from heterogeneous firms and substantial intra-industry reallocations take place, i.e. high productivity firms squeeze out low productivity firms. Previous tax-tool comparisons have not included these central forces of industry structure. This paper examines a general equilibrium monopolistic competition model with heterogeneous firms and intra-industry reallocations. We show that the welfare superiority of ad valorem over unit taxes under imperfect competition is not only preserved but amplified. The additional difference between the tools arises because unit taxes distort relative prices, which in turn reduces average industry productivity through reallocations (the survival and increased market share of lower productivity firms). Importantly, numerical solutions of the model reveal that the relative welfare loss from using the unit tax increases dramatically in the degree of firm heterogeneity.  相似文献

This paper develops a flexible approach to combine forecasts of future spot rates with forecasts from time-series models or macroeconomic variables. We find empirical evidence that, accounting for both regimes in interest rate dynamics, and combining forecasts from different models, helps improve the out-of-sample forecasting performance for US short-term rates. Imposing restrictions from the expectations hypothesis on the forecasting model are found to help at long forecasting horizons.  相似文献

Migration is a risky behaviour because of the uncertainty about future wages, living conditions, changing relationships with family and friends and cultural adjustment. While there has been some research on risk and uncertainty in migration, this has mostly been approached as a form of ‘rational’ decision-making: such approaches explain why some groups of individuals are more likely than others to migrate, but are limited in explaining individual variations in behaviour within these groups. Individual migrants vs. non-migrants are self-selected in terms of tolerance of risk and uncertainty but, with very few exceptions, there has been no research on migration within the framework of risk tolerance/aversion and competence to manage risk. Moreover, existing research is based on, and constrained by the limitations of, incumbent data-sets. Drawing on a specially commissioned large-scale survey of the UK population, this paper uses principal component analysis and logistic regression to analyse the extent to which risk and risk-related measures can be used to predict four different types of mobility profiles. There are significant associations between these individual mobility characteristics and general risk/uncertainty tolerance, and competence-based tolerance. These are strongest in terms of the two most polarised mobility types: the least mobile, the Stayers, and the most mobile, the Roamers. Recognising that previous migration is exogenous, a further analysis of migration intentions, with previous migration included as an independent variable, finds the propensity for future migration is, in fact, negatively associated with previous migration, probably due to the importance of ‘pure risk’ as opposed to acquired competence via migration experience, and to life cycle considerations.  相似文献

This paper implements strategies that use macroeconomic variables to select European equity mutual funds, including Pan-European, country, and sector funds. We find that several macro-variables are useful in locating funds with future outperformance and that country-specific mutual funds provide the best opportunities for fund rotation strategies using macroeconomic information. Specifically, our baseline long-only strategies that exploit time-varying predictability provide four-factor alphas of 12–13% per year over the 1993–2008 period. Our study provides new evidence on the skills of local versus Pan-European asset managers, as well as how macroeconomic information can be used to locate and time these local fund manager skills.  相似文献

The actual degree of independence of the Federal Reserve has varied over the years. This paper traces its history and finds that the Federal Reserve has been most successful in its dual full-employment, low inflation mandate when it follows fixed rules, and focuses on the intermediate term rather than trying to react to short-term developments under political pressure. Going forward, monetary policy should emphasize on annual monetary growth more and short-term interest rates less. A number of policies are recommended to support this overall emphasis on intermediate-term stability.  相似文献
