The paper describes the current situation in the salt industry. It points to the inadmissibly high and expanding market share of imported salt products despite the country’s own colossal resource base and the domestic enterprises’ huge unused capacities. It has been shown that OAO Russian Railroads (OAO RZhD) will economically benefit due to its reasonable policy of selective reduction of the railroad shipment tariffs for salt for domestic producers due to the inevitable growth of the country’s own salt output.  相似文献

This article, focusing on Seebohm Rowntree's poverty surveys, considers the importance and durability of the concept of secondary poverty. It argues that secondary poverty was a central component of Rowntree's first survey of York, carried out in 1899, and in his lectures and writing in the Edwardian period. Moreover, secondary poverty remained an important feature of Rowntree's analysis during the interwar years and after the Second World War, and was adopted by other researchers in various ways. Although secondary poverty was not seriously examined in the published version of Rowntree's 1936 York survey, there is evidence that it was originally intended to feature, and it is clear that impressionistic evidence of poverty was gathered by Rowntree's investigators, as had been the case in 1899. Moreover, although it was completely expunged from the third survey of York, carried out by Rowntree and Lavers in 1950, a separate inquiry into secondary poverty was carried out in the early 1950s, with a number of prominent supporters. Subsequently, dissatisfaction with income‐based definitions and measurements of poverty allowed the concept of secondary poverty to continue to exercise an influence on the study of poverty in the postwar period.  相似文献

Fertilizer use in Nigeria is estimated at 13 kg/ha, which is far below the 200 kg/ha recommended by the Food and Agricultural Organization (FAO). The objective of this investigation was to identify the determinant factors of farmers’ participation in Nigeria's Growth Enhancement Support Scheme (GESS). In addition, we determined the impact of the GESS on fertilizer use in rural areas. A total of 1,200 rural farmers were sampled across the six geopolitical zones of Nigeria. Results from the use of a recursive bivariate probit model indicated that GESS significantly impacted on the access and usage of fertilizer among the rural farmers; and that contact with extension agents, ownership of mobile phones, power for charging phone batteries, value output, mobile network coverage, ability to read and write were positive determinants of rural farmers’ participation in the GESS; whereas increased distance to registration and collection centers, and cultural constraints to married women reduced farmers’ tendency to participate in the GESS. The findings suggest that farmers’ participation in the GESS is a critical factor for raising fertilizer use in Nigeria. This implies that food security in sub‐Saharan Africa can be achieved by increasing the participation of rural farmers in the GESS.  相似文献

We consider the efficiency properties of exchange economies where privately informed traders behave strategically. Specifically, a competitive mechanism is any mapping of traders’ reports about their types to an equilibrium price vector and allocation of the reported economy. In our model, some traders may have non-vanishing impact on prices and allocations regardless of the size of the economy. Although truthful reporting by all traders cannot be achieved, we show that, given any desired level of approximation, there is such that any Bayesian-Nash equilibrium of any competitive mechanism of any private information economy with or more traders leads, with high probability, to prices and allocations that are close to a competitive equilibrium of the true economy. In particular, allocations are approximately efficient. A key assumption is that there is small probability that traders behave non-strategically.  相似文献

In the contract-theoretic literature, there is a vital debate about whether contracts can mitigate the hold-up problem, in particular when renegotiation cannot be prevented. Ultimately, this question has to be answered empirically. As a first step, we have conducted a laboratory experiment with 960 participants. We consider investments that directly benefit the non-investing party. While according to standard theory, contracting would be useless if renegotiation cannot be ruled out, we find that option contracts significantly improve investment incentives compared to a no-contract treatment. This finding might be attributed to Hart and Moore?s (2008) recent idea that contracts can serve as reference points.  相似文献

The popularity of online rate-and-review websites has increased the importance of word-of-mouth (WOM) volume (number of ratings) yet the retail literature has not paid adequate attention to understanding its impact. This paper highlights WOM volume as a high-scope, decision-making cue upon which the influence of other WOM-relevant characteristics on a WOM message's persuability depends. We begin, via a pretest, by demonstrating the intuitive expectation that high volume, relative to low volume, accentuates or assimilates perceptions of positivity or negativity of WOM targets. Then, through two experimental studies, we show that depending upon how high volume interacts with WOM consensus and consumer decision precommitment, it can contrast preference away from the valence of a target also. In our third and final experimental study, we demonstrate that consumers differ in their susceptibility to the influence of high volume. Those with a higher desire to be different from others, compared to those with a higher desire to be similar, are resistant to high volume's assimilative sway and do not show the valence-accentuating effects demonstrated in the pretest. Retail managers and researchers should find these insights about the different roles of WOM volume beneficial.  相似文献
