Over the last two decades, millet prices in Niger have enjoyed periods of spectacular increase during which they seem to go well above their fundamental value. These episodes of price bursts followed by rapid reversals could be attributed to the presence of rational speculative bubbles....

The aim of this study is to assess whether fuel prices in Greece respond asymmetrically to changes in the global oil prices. To do so, we depart from the current practice in the literature that focuses on fuel prices. Rather, we consider the mark-up of both the refineries and retailers. Even...

Basic annual cross sections of market on accounting values are estimated in levels and returns using a 30 US firm by 50 year panel of data. Log transformations of the levels data are shown to produce an improved statistical specification. Deflated returns models are shown to suffer from other...

In this paper we review the existing empirical literature on price asymmetries in commodities, providing a way to classify and compare different studies which are highly heterogeneous in terms of econometric models, type of asymmetries and empirical findings. Relative to the previous literature,...

In this paper we investigate crude oil and products price dynamics. We present a comparison among ten price series of crude oils and fourteen price series of petroleum products, considering four distinct market areas (Mediterranean, North Western Europe, Latin America and North America) over the...

The crisis that hit the Greek economy over 2008-2016, made clear that the economy’s growth model was characterised by structural weaknesses. During the current transition period, it is imperative to develop a new growth model that will rely largely on investment. Moreover, investment should be...

The present paper investigates whether Greek gasoline prices respond symmetrically to changes in international oil prices. The study uses all available observations and applies the TAR (Threshold Auto-Regressive) methodology, which is considered to be the most reliable econometric technique...

The existing literature on price asymmetries does not systematically investigate the sensitivity of the empirical results to the choice of a particular econometric specification. This paper fills this gap by providing a detailed comparison of the three most popular models designed to describe...

Modern economies have been subjected to a number of shocks during the past several years such as the burst of the Internet bubble, terrorist attacks, corporate scandals, the war in Iraq, the uncertainty about energy prices, and the recent subprime mortgage crisis. In particular, during the last...
