A bstract .   Even the most passionate defenders of free trade, such as Mises and Rothbard, claim that trade cannot occur under conditions of strict homogeneity of land, labor, and capital. We show that specialization, trade, and the division of labor can emerge even when resources are initially homogenous, due to "natural heterogeneity," economies of scale, and learning.  相似文献

Bond laddering is a popular fixed-income investment strategy. The main purpose of this paper is to develop a methodology for determining private investors’ most interest rate risk (IRR)-return-efficient investment horizon for bond ladders (BLs), which are virtually free of credit risk. Two IRR measures of a continuously rolling and homogenous BL (CRHBL) are analytically derived under the assumption that interest rates are martingales. The first measure is the modified duration, which assumes a flat term structure of interest rates. However, this assumption is not fully supported by the empirical data and, thus, an additional IRR measure is proposed. Under each of these two measures, the ratios between the annual return in excess of the demand deposit rate and IRR of CRHBLs with different investment horizons are calculated. As expected, CRHBLs with rather low IRR are most risk-return-efficient. The results for the theoretical CRHBLs also apply to “real-world” discrete BLs. Thus, the proposed methodology can help private investors construct IRR-return-efficient discrete BLs.  相似文献

We study the role of beauty in politics using candidate photos that figured prominently in electoral campaigns. Our investigation is based on visual assessments of 1929 Finnish political candidates from 10,011 respondents (of which 3708 were Finnish). As Finland has a proportional electoral system, we are able to compare the electoral success of non-incumbent candidates representing the same party. An increase in our measure of beauty by one standard deviation is associated with an increase of 20% in the number of votes for the average non-incumbent parliamentary candidate. The relationship is unaffected by including education and occupation as control variables and withstands several other robustness checks.  相似文献

早在10年前,在欧元创立之初,欧元的国际地位就被提上了国际议程。随着全球金融危机的爆发,对美元的全球角色的质疑日渐增多,欧元受到了进一步关注。然而,当美元的国际地位备受审查时,欧盟及其货币还没有承担起任何积极主动的角色。本文探讨的是,欧元是否能逐渐成为国际货币,不仅在欧盟及其他国家的贸易中,还要在第三国之间的贸易中被使用,即欧元是否能挑战美元的当前地位,在国际货币体系中成为主要储备货币。  相似文献

Low agricultural productivity remains the primary source of poverty in the developing regions and yet little is known about the influence on agricultural productivity of domestic and international accumulated R&D knowledge and the channels through which this knowledge is transmitted internationally. Following a large scientific literature, this article argues that R&D and R&D knowledge spillover are ecozone‐specific and, therefore, are transmitted internationally through ecozones, where ecozones are the broadest biogeographic division of the earth's land surface. Using data for a panel of 88 countries, it is shown that international knowledge spillovers are ecozone‐specific and have been an important contributing factor behind the marked widening of the income gap between developed and developing countries since 1983.  相似文献

Using data for a long panel of 90 developed and developing countries, this article explores the effects of research and development (R&D) and fixed capital stock on agricultural land productivity over the period 1961–2012. Instruments are used for R&D to deal with feedback effects and measurement errors. The results show very high social returns to investment in R&D and to fixed capital stock, suggesting that increasing investment in these factors are promising ways of arresting the increasing food prices due to increasing demand for animal protein, population growth, desertification, salinization, soil erosion, climate change, and decreasing growth in land productivity.  相似文献

Efficiency and security are often regarded as opposing factors in transport operations, with increased security causing decreased efficiency. The use of information technology holds the promise of enabling improved efficiency in freight transport operations and this article suggests and elaborates on the proposition that “An increased focus on efficiency will result in improved security for carrier operations.” The research for this article involved a literature review, the collection of empirical data through one in‐depth case study, and elaboration on a proposition through a field pilot implementation. The selected focus was carrier operations in connection with port terminals carrying out RoRo operations on trailers. The article explores and describes how measures to increase efficiency result in increased security.  相似文献

This paper measures “debt disputes” between governments and foreign private creditors in periods of sovereign debt crises. We construct an index of government coerciveness, consisting of 9 objective sub-indicators. Each of these sub-indicators captures unilateral government actions imposed on foreign banks and bondholders. The results provide the first systematic account of debt crises that goes beyond a binary categorization of default versus non-default. Overall, government behavior and rhetoric show a strong variability, ranging from highly confrontational to very smooth crisis resolution processes. In a preliminary analysis on the determinants of coercive behavior, we find political institutions to be significant, while economic and financial factors play a lesser role. These results open up an agenda for future research.  相似文献
