This paper aims to study, in the most recent historical time period, the efficiency of the Paris Stock Exchange market. We test its weak form while analysing the stock exchange returns series by nonparametric methods, using kernel methodology in particular. In doing so, our approach extends the traditional view treating the observed cyclical fluctuations on this market. 相似文献

This article estimates how storage losses from mold, insects, and other pests, combined with liquidity constraints, influence a smallholder farm household's decision to store maize on farm after harvest. We analyze panel data from 309 smallholders in Benin covering the 2011 and 2013 harvest seasons. Results suggest that smallholders are driven to sell at harvest time for different reasons, depending on their motivation for storing. In households that report direct consumption as their primary goal for storing maize, liquidity constraints, not storage losses, reduce the amount they store. In contrast, households that store maize with the intention of selling it later in the year appear unaffected by liquidity constraints. Instead, these households store less when they expect to lose more during storage. These results suggest that policies to provide liquidity will be more helpful in motivating storage among consumption‐oriented households. Households motivated to store for later sale will benefit from modern storage technologies that mitigate the operational costs associated with storage losses. 相似文献

Anti-Americanism and Francophobia express a consistent hostility toward the government, culture, history or people of the US and France or the Francophonie (the global community of French-speaking peoples). This study explores interactions between country-of-origin (COO) effects and animosity expressed through anti-Americanism and Francophobia through analysis of scholarly studies, several decades of articles from the general and online press in the US and France, and ethnographic fieldwork in France and the US results reveal interesting inconsistencies and variability in national expressions of consumer animosity and response to COO cues over the time of the study, underlining the need for further longitudinal study of animosity, COO effects and consumer response. Implications of findings are examined with reference to theory development, marketing practice, and public policy. 相似文献

Using a non-parametric technique for data from 1995 to 2004, we investigate the cost and profit efficiency of 28 Chinese commercial banks. We examine the influence of ownership type, size, risk profile, profitability and key environmental changes on the bank efficiency using a Tobit regression. Consistent with the existing literature, we find that profit efficiency levels are well below those of cost efficiency. This suggests that the most important inefficiencies are on the revenue side. Our findings are also consistent with prior evidence on ownership and efficiency: joint-stock banks (national and city-based), on average, appear to be more cost- and profit-efficient than state-owned banks while medium-sized banks are significantly more efficient than small and large banks. These and other results suggest the need for speedier reforms to open the banking market, improving risk management, minimizing the government's capital subsidy and diversifying ownership of Chinese banks. 相似文献

Recognized as one of the most unique archaeological sites in the world, the Giza pyramids plateau is the location of the three great pyramids and the Sphinx, tombs, seven smaller pyramids, and other monuments. Over the centuries the plateau has been instrumental in introducing Egyptian civilization to the world, and was recently declared as one of the most iconic travel spots on the planet.In recent years, the location of the new Grand Egyptian Museum (GEM) within the site of the plateau re-ignited the debate between scholars, practitioners and activists over development activities within and around this unique site. Consequently, a growing conflict re-emerged between conserving the plateau and developing the surrounding areas. Additionally, this invaluable site is threatened by urban expansion and development, pollution, rising groundwater and extensive tourism. Yet, currently there are neither tourism management nor development plans for the site.Building on national and international conservation conventions and charters, this paper explores analyses and documents the current gap between ideal conservation management sittings within and around the pyramids plateau and the reality of urban development trends and tourism activities. 相似文献

This paper presents a methodological extension of Deaton's (1990) model for estimating price elasticities, by pooling Tunisian
data from several surveys to improve the inter-cluster variability of unit values which is one of the key elements used in
the derivation of these elasticities. Since the surveys cover a relatively long period, possible structural changes in consumption
behaviour occurring over time are accounted for by postulating that certain response coefficients of the basic model vary
from one survey to the other. The own price and cross price elasticities calculated using appropriate estimates of the extended
model are satisfactory both from the economic point of view of their sign and the statistical point of view of their significance
and superior to those obtained using a single survey.

We study a general family of Anderson–Rubin-type procedures, allowing for arbitrary collinearity among the instruments and endogenous variables. Using finite-sample distributional theory, we show that the proposed procedures, besides being robust to weak instruments, are also robust to the exclusion of relevant instruments and to the distribution of endogenous regressors. A solution to the problem of computing linear projections from general possibly singular quadric surfaces is derived and used to build finite-sample confidence sets for individual structural parameters. The importance of robustness to excluded instruments is studied by simulation. Applications to the trade-growth relationship and to education returns are presented. 相似文献
