This paper presents MAcMap–HS‐6, a database providing a consistent, ad valorem equivalent measure of tariff duties and tariff rate quotas for 163 countries and 208 partners, at the six‐digit level of the Harmonized System (5111 products), accounting for all preferential agreements. We describe the methodology used to compute and aggregate an ad valorem equivalent of applied protection. Emphasis is placed on minimizing the endogeneity bias in the aggregation procedure, while acknowledging structural differences in export specialization. The resulting quantitative assessment is illustrated by giving an overview of applied protection across the world in 2001, in terms of average as well as distribution.  相似文献

It has been claimed that, for dynamic investment strategies, the simple act of rebalancing a portfolio can be a source of additional performance, sometimes referred to as the volatility pumping effect or the diversification bonus because volatility and diversification turn out to be key drivers of the portfolio performance. Stochastic portfolio theory suggests that the portfolio excess growth rate, defined as the difference between the portfolio expected growth rate and the weighted-average expected growth rate of the assets in the portfolio, is an important component of this additional performance (see Fernholz [Stochastic Portfolio Theory, 2002 (Springer)]). In this context, one might wonder whether maximizing a portfolio excess growth rate would lead to an improvement in the portfolio performance or risk-adjusted performance. This paper provides a thorough empirical analysis of the maximization of an equity portfolio excess growth rate in a portfolio construction context for individual stocks. In out-of-sample empirical tests conducted on individual stocks from 4 different regions (US, UK, Eurozone and Japan), we find that portfolios that maximize the excess growth rate are characterized by a strong negative exposure to the low volatility factor and a higher than 1 exposure to the market factor, implying that such portfolios are attractive alternatives to competing smart portfolios in markets where the low volatility anomaly does not hold (e.g. in the UK, or in rising interest rate scenarios) or in bull market environments.  相似文献

Urban growth is a major theme in economic development and a policy imperative for developed countries that seek to create sustainable cities. We argue that the past weighs heavily on the ability of societies to sustainably manage urban environments. The policy implications of urban history are revealed in comparisons of cities across times and between places. The special issue presents some of the best recent work on the economic and social history of Australian cities. We aim to encourage historians to incorporate urban variables into studies of historical processes and to persuade policymakers to consider historical trends in their analysis.  相似文献

Bilateral trade of cultural goods   总被引:3,自引:0,他引:3  
International trade flows of cultural goods have grown rapidly over the last decades and their liberalization will be an important issue of future multilateral trade negotiations. In this paper, we focus on bilateral trade in cultural goods and investigate its determinants. Furthermore, we use trade in cultural goods as a proxy for countries’ cultural proximity and study if countries with proximate cultural tastes have more intense bilateral exchanges. Our estimations show a positive and significant influence of cultural flows on overall trade, suggesting that regulations fostering domestic cultural creation might have impacts going beyond what is generally expected.  相似文献

Using American panel data from the National Education Longitudinal Study of 1988, this article investigates the effect of working during grade 12 on attainment. We employ, for the first time in the related literature, a semiparametric propensity score matching approach combined with difference‐in‐differences. We address selection on both observables and unobservables associated with part‐time work decisions, without the need for instrumental variable. Once such factors are controlled for, little to no effects on reading and math scores are found. Overall, our results therefore suggest a negligible academic cost from part‐time working by the end of high school.  相似文献

This article reviews trends in poverty, economic policies, andgrowth in a sample of African countries during the 1990s, drawingon the better household data now available. Experiences havevaried. Some countries have seen sharp drops in income poverty,whereas others have witnessed marked increases. In some countriesoverall economic growth has been pro-poor and in others not.But the aggregate numbers hide systematic distributional effects.Taking both macro and micro perspectives of growth and povertyin Africa, the article draws four key conclusions. First, economicpolicy reforms (improving macroeconomic balances and liberalizingmarkets) appear conducive to reducing poverty. Second, marketconnectedness is crucial to enable participation in the gainsfrom economic growth. Some regions and households by virtueof their remoteness were left behind when growth picked up.Third, education and access to land emerge as key private endowmentsto help households benefit from new economic opportunities.Finally, rainfall variations and ill health have profound effectson poverty outcomes, underscoring the significance of socialrisk management in poverty reduction strategies in Africa.  相似文献

Bettors are subject to an optimistic bias when betting on the team they support. This paper shows that this individual bias does not affect betting odds on British teams in association football (soccer), as it is often argued.  相似文献
