The frequent and excessive fluctuation of agricultural and livestock products price is not only harmful to residents’ living, but also affects CPI (Consumer Price Index) values, and even leads to social crisis, which influences social stability. Therefore it is important to forecast the price of agriculture and livestock products. As a result, we make a research on the factors affecting agricul...

over the past three decades vertical price transmission analysis has been the subject of considerable attention in applied agricultural conomics. it has been argued that the existence of asymmetric price transmission generates rents for marketing and processing agents. retail prices allegedly move faster upwards than downwards in response to farm level pricemovements. this is an important issue...

This paper concerns with two reasons for stock price fluctuation, the instinctive stochastic fluctuation and the fluctuation caused by the spread of information. They are constructed by compound Poisson process and continuum percolation model separately. Combining the two models, the authors get a Lévy process for the price fluctuation that can explain the fat-tail phenomenon in stock market. T...

The study investigates consumers’ preference for cowpea reflected in the Nigerian markets through price discounts and premiums that consumers pay for different cowpea characteristics. The price data used for this study were obtained through a market survey. A common data collection protocol was employed. Every month, between October 2009 to December 2010, five cowpea samples per seller were bou...

We propose a model of price competition where consumers exogenously differ in the number of prices they compare. Our model can be interpreted either as a non–sequential search model or as a network model of price competition. We show that i) if consumers who previously just sampled one firm start to compare more prices all types of consumers will expect to pay a lower price and ii) if consumers...

In the interconnected world of today, large-scale multi-agent networked systems are ubiquitous. This thesis studies two classes of multi-agent systems, where each agent has local information and a local objective function. In the first class of systems, the agents are collaborative and the overall objective is to optimize the sum of local objective functions. This setup represents a general fam...

The stock price has long been an essential issue in stock market analysis, while rarely had any relevant study covered the relational effect of the bidder factor on stock price. Hereby we try to find an association between bid and transaction price time series. The fluctuation of pattern ratios embedded in the bid series affects the fluctuation of transaction price. That means when there is sma...

For many goods and services, such as cellular-phone service and debit-card transactions, the marginal price of the next unit of service depends on past usage. As a result, consumers who are inattentive to their past usage may be aware of contract terms and yet remain uncertain about the marginal price of the next unit. I develop a model of inattentive consumption, derive equilibrium pricing whe...

This paper examines the dynamic effects of oil price shocks in addition to the aggregate supply and demand shocks on macroeconomic fluctuations in four sample economies: Indonesia, Malaysia, Pakistan and Thailand. We aim to discover whether oil price shocks play a crucial role in explaining output and domestic price fluctuation in small emerging economies after 1990s. We are also keen to assess...
