Abstract This paper applies a new approach to the identification of discourses, based on Multiple Correspondence Analysis (MCA), study discourse variation over time. The MCA keywords deals with major issue use identify discourses: allocation individual multiple discourses. Yet, as this demonstrates, also allows us observe in prevalence discourses texts patterns keyword co-occurrence. Metadata c...

Economists have not been altogether successful in their efforts to forecast “core” inflation—an inflation measure that typically excludes volatile food and energy prices. One possible explanation is that the models used to make these forecasts fail to distinguish the forces influencing price changes in core services from those affecting price changes in core goods. While core services inflation...

The fluctuation of vegetable prices in recent years underscores the need to identify contributing factors and develop effective policies. In order examine affecting prices, this paper uses a structural model constructed by demand, supply, import, export functions decompose price variance, also performs numerical simulation generalize results. We studied Korean market, selected cabbage, radish, ...

Economists often comment that inflation will tend to increase (or decrease) if growth is higher or lower than the 'potential' growth rate of the the economy. After setting out a theoretical justification for such a relationship we estimate equations relating the change in inflation to growth rates for the US, Canada and Australia. Our system also allows for the possibility that traded goods pri...

Using a novel dataset we examine the pricing behavior of Indian exporters, in particular looking at the relationship between export prices and firm capability (productivity) conditioning on the quality of imported inputs that firms use. Conditioning on firm productivity among firms that directly import, higher quality (higher price) imports are associated with higher quality (higher price) expo...

We estimate a structural model of a sponsored search auction model. To accommodate the “position paradox”, we relax the assumption of decreasing click volumes with position ranks, which is often assumed in the literature. Using data from “Website X”, one of the largest online marketplaces in China, we find that merchants of different qualities adopt different bidding strategies: high quality me...
