This paper formulates and analyzes a relatively simple model of duopoly pricing under conditions of fluctuating demand. Price-setting firms produce a homogenous product subject to increasing marginal cost of production. We focus on static Nash equilibria in price choices and examine the impact of varying the level of demand on equilibrium price levels, markups of price over marginal cost, and p...

We investigate the degree to which the wheat markets of France, Germany and the United Kingdom are in spatial equilibrium and how reforms to the CAP affect the speed of convergence to the long run relationship. Due to the interrelationship among these markets and the nonstationarity of our data we introduce a seemingly unrelated regression augmented Dickey-Fuller and error correction methodolog...

İklim değişikliğinin, son yıllarda tarımsal üretimde yol açtığı problemlerin yanı sıra, Covid-19 salgın sürecinin tedarik zincirinde aksamalara neden olması ve girdi maliyetlerindeki artışlar küresel gıda fiyatlarını yükseltmiştir. Küresel arzında yaşanan kaygılar fiyat artışları hükümetlerin öncelikli gündemleri arasında yer almıştır. Bu çalışmada, Türkiye’nin 2006-2021 dönemi için genel üreti...

Differences in price dynamics across retail chains, even for identical products, offer the opportunity to provide new insights into determinants of transmission. Specifically, we highlight role strategic complementarity and mark-up elasticities as factors underpinning Using supermarket data on a sample orange juice coffee products from seven largest chains UK, results show that ignoring exerts ...

Identifying the drivers of global crop price fluctuations is essential for estimating the risks of unexpected weather-induced production shortfalls and for designing optimal response measures. Here we show that with a consistent representation of storage dynamics, a simple supply–demand model can explain most of the observed variations in wheat prices over the last 40 yr solely based on time se...
