This investigation attempts to compare rice producers' response to price and yield expectations in terms of changes in the planted area in different Indian states under two decades of planning. It provides an explanation of why the response function may differ between the states and offers supporting evidence. 相似文献

The American presidential election is one of the largest, most expensive, and most comprehensive marketing efforts. Despite this fact, marketing scholars have largely ignored this campaign, as well as thousands of others for congresspersons, senators, and governors. This article describes the growth of interest in research issues related to political marketing. This emerging research area lies at the crossroads of marketing and political science, but these fields have developed largely independent of one another with little cross-fertilization of ideas. We discuss recent theoretical, empirical, and behavioral work on political campaigns, integrating perspectives from marketing and political science. Our focus is on (1) the extent to which paradigms used in goods and services marketing carry over to the institutional setting of political campaigns, (2) what changes are necessary in models and methodology to understand issues in political marketing and voter behavior, and (3) how the special setting of politics may help us gain a better understanding of certain topics central to marketing such as advertising, branding, and social networks. 相似文献

The article examines the efficiency of 31 stock index series spanning 26 countries across the world, using generalized spectral test (GST) and detects departure from the martingale difference hypothesis (MDH). A moving window of 24 months was used and p-values of GST were estimated. In order to explore whether the departure from market efficiency can be used for generating profitable trades, an exponentially weighted-moving-average-based trading rule was applied and was found that average profits per trade were significantly higher when p-value of the GST was less than 0.1. These observations are in consistent with the adapted market hypothesis. 相似文献

The aims of this paper are two-fold. First, we present a survey of recent extrapolative long-run forecasts of world fertilizer production and consumption to the year 2000, including our own forecasts for this period. Second, we examine critically the various approaches that have been suggested in the study of short-run fluctuations in demand and supply for individual countries which have a great bearing on short-run economic policy. In particular, the models due to Griliches and Timmer are discussed and evaluated, and an alternative approach is suggested. 相似文献

The benefits of a stress‐tolerant crop become visible under the stresses that the crop is tolerant against. We investigate the adoption of submergence‐tolerant rice in northern Bangladesh by using panel data of 461 households, interviewed in 2013 and 2015. The sample households were randomly selected in 31 villages where submergence‐tolerant rice seeds were given to a small number of farmers in each village. The results from the household fixed‐effects model indicate that submergence in the previous year increased the adoption of submergence‐tolerant rice. The adoption impact was larger among farmers who were neighbors of early seed recipients. Our results suggest that being neighbors of early seed recipients may have helped the neighboring farmers observe the benefits of the submergence‐tolerant rice under submergence. The results indicate the importance of the information flow from early recipients to neighboring farmers. 相似文献

Buyer–Seller networks are pervasive in developing economies yet remain relatively understudied. Using primary data on contracts between the largest tractor assembler in Pakistan and its suppliers we find large variations in prices and quantities across suppliers of the same product. Surprisingly, “tied” suppliers – those that choose higher levels of specific investments – receive lower and more unstable orders and lower prices. These results are explained by developing a simple model of flexible specialization under demand uncertainty. A buyer faces multiple suppliers with heterogeneous types to supply customized parts. Specific investments raise surplus within the relationship but lower the seller's flexibility to cater to the outside market. Higher quality suppliers have a greater likelihood of selling outside and so this cost is greater for them. Therefore even if a buyer typically prefers high types, some low type suppliers might be kept as marginal suppliers because of their greater willingness to invest more in buyer-specific assets. Further empirical examination shows that the more tied suppliers are indeed of lower quality. 相似文献
