This article presents new results on the relationship between income inequality and education expansion – that is, increasing average years of schooling and reducing inequality of schooling. When dynamic panel estimation techniques are used to address issues of persistence and endogeneity, we find a large, positive, statistically significant and stable relationship between inequality of schooling and income inequality, especially in emerging and developing economies and among older-age cohorts. The relationship between income inequality and average years of schooling is positive, consistent with constant or increasing returns to additional years of schooling. While this positive relationship is small and not always statistically significant, we find a statistically significant negative relationship with years of schooling of younger cohorts. Statistical tests indicate that our dynamic estimators are consistent and that our identifying instruments are valid. Policy simulations suggest that education expansion will continue to be inequality reducing. This role will diminish as countries develop, but it could be enhanced through a stronger focus on reducing inequality in the quality of education. 相似文献

Value at Risk (VaR) forecasts have been increasingly accepted globally by both risk managers and regulators as a tool to identify and control exposure to financial market risk. However, modern portfolios are characterized by a constantly changing composition of security holdings that reflect portfolio managers’ strategies, expected prices, and net cash flows into the portfolio. As a result of these factors, portfolio returns are time-varying mixtures of distributions which are unlikely to be well approximated by conventional methods. 相似文献

The Greenspan years: an analysis of the magnitude and speed of the equity market response to FOMC announcements 总被引:1,自引:1,他引:0

We examine the impact of monetary policy on the S&P 500 using intraday data. The analysis shows an economically and statistically
significant relationship between S&P 500 intraday returns and changes in the Fed funds target rate. The significance and magnitude
of the response is dependent on whether the change was expected or unexpected. An expected change in the Fed funds target
rate has no impact on prices in the broad equity market; however, an unexpected change of 25 basis points in the Fed funds
target rate results in an approximate 48 basis points decline in the broad equity market’s return. The speed of these market
reactions is rapid with the equity market reaching a new equilibrium within 15 minutes.

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

Ad valorem versus unit taxes: monopolistic competition, heterogeneous firms, and intra-industry reallocations 总被引:1,自引:1,他引:0
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
