There is little work on the inner workings of journals. What factors seem to affect the ability to publish in a journal? Could simple rules (which are already used by some journals) like the desk rejection of a significant minority of papers, help to streamline the process? At what cost? How well do journals seem to do in choosing papers? What can we say about the extent of type 1 and type 2 errors? Do editors seem to have uniform standards or are some harsher than others? We use data on submissions to the Journal of International Economics to help answer these questions.  相似文献

Empirical studies show that the fertility rate (mortality rate) exhibits an inverted u‐shaped dynamic in some countries, while it decreases monotonically in other countries. This paper formulates the concept of public health infrastructure and constructs a growth model that replicates various historically observed patterns of fertility and mortality rates.  相似文献

The simultaneous berth and quay crane allocation problem   总被引:3,自引:0,他引:3  
This paper addresses efficient berth and crane allocation scheduling at a multi-user container terminal. First, we introduce a formulation for the simultaneous berth and crane allocation problem. Next, by employing genetic algorithm we develop a heuristic to find an approximate solution for the problem. The fitness value of a chromosome is obtained by crane transfer scheduling across berths, which is determined by a maximum flow problem-based algorithm based on a berth allocation problem solution defined by the chromosome. The results of numerical experiments show that the proposed heuristic is applicable to solve this difficult but essential terminal operation problem.  相似文献

Resource allocation mechanisms used in the market and within the firm are quite often a mixture of the pure market principle and the pure organization principle. Market principles penetrate into the firm's resource allocation and organization principles creep into the market allocation. Interpenetration occurs to remedy the failure of pure principles other in the market or in the organization. After presenting this new perspective, we analyze resource allocation mechanisms in Japan and the U.S. One conclusion is that interpenetration patterns are rather different between the two countries due to institutional, economic and societal differences. We also analyze the ways in which these differences affect Japanese and American corporate behavior in such areas as diversification strategy, corporate financing, and innovation and venture business activity.  相似文献

This paper asks whether the results obtained from using the standard approach to testing the influential Grossman and Helpman “protection for sale” model of political economy might arise from a simpler setting. A model of imports and quotas with protection occurring in response to import surges, but only for organized industries, is simulated and shown to provide parameter estimates consistent with the protection for sale framework. This suggests that the standard approach may be less of a test than previously thought.  相似文献

This paper uses a unique data set on the spreads of subordinated debts issued by Japanese banks to investigate the presence of market monitoring. The results show that subordinated debt investors punished weak banks by requiring higher interest rates. Moreover, I find that the spreads and the sensitivity of spreads to Moody’s bank ratings both increased dramatically after the Japanese government allowed a large city bank, Hokkaido Takushoku Bank, to fail and passed the Financial Reform Act and the Rapid Revitalization Act in the late 1990s. These results suggest that the decline of conjectural guarantee led to the emergence of market monitoring. In addition, I find the relationship between spreads and accounting measures of bank risk to be quite fragile.  相似文献

This study examines whether household access to microfinance reduces poverty in Pakistan and, if so, how and to what extent. It draws on primary empirical data gathered by interviewing 1132 households, including both borrower and non-borrower households, in 2008–2009. Sample selection biases have been partially controlled for by using propensity score matching. The study reveals that microfinance programmes had a positive impact on the participating households. Poverty-reducing effects were observed on a number of indicators, including expenditure on healthcare, clothing and household income, and on certain dwelling characteristics, such as water supply and the quality of roofing and walls.  相似文献

We obtain explicit representations of locally risk-minimizing strategies for call and put options in Barndorff-Nielsen and Shephard models, which are Ornstein–Uhlenbeck-type stochastic volatility models. Using Malliavin calculus for Lévy processes, Arai and Suzuki (Int. J. Financ. Eng. 2:1550015, 2015) obtained a formula for locally risk-minimizing strategies for Lévy markets under many additional conditions. Supposing mild conditions, we make sure that the Barndorff-Nielsen and Shephard models satisfy all the conditions imposed in (Arai and Suzuki in Int. J. Financ. Eng. 2:1550015, 2015). Among others, we investigate the Malliavin differentiability of the density of the minimal martingale measure. Moreover, we introduce some numerical experiments for locally risk-minimizing strategies.  相似文献

This paper studies the impact of taxation on poverty and ex ante vulnerability of households in rural China based on national household survey data in 1988, 1995 and 2002. It has been confirmed that (i) poverty and vulnerability have reduced significantly with a great deal of geographical disparity; (ii) education, land, and access to infrastructure and irrigation facilities are the key factors to reduce vulnerability; and (iii) the highly regressive tax system increased farmers’ poverty and vulnerability. The abolishment of rural tax since 2006 would thus have a significant negative impact on both poverty and vulnerability of rural households.  相似文献
