abstract the objective of this study is to investigate the long run and short run interactions between agricultural trade liberalization and shares of the two sectors of agriculture and services in the total export and import products and services of iran during the years 1961-2008. to figure out interactions, the vector correction model was used. the ratio of the sum of imports and exports to ...

This paper experimentally investigates behavior in sequential one-shot transactions which are governed by non-binding contracts. In a second, incomplete information treatment, contracts are binding for some players. While according to traditional game-theoretical analysis no trade is expected in the first treatment, full trade should result in the latter. However, we find that trade is even hig...

Multi-armed bandit problems are the most basic examples of sequential decision problems with an exploration–exploitation trade-off. This is the balance between staying with the option that gave highest payoffs in the past and exploring new options that might give higher payoffs in the future. Although the study of bandit problems dates back to the 1930s, exploration–exploitation trade-offs aris...

The negative effect of distance on bilateral trade is one of the most robust findings in international trade. However, the underlying causes of this negative relationship are less well understood. This paper exploits a temporary shock to distance, the closing of the Suez canal in 1967 and its reopening in 1975, to examine the effect of distance on trade and the effect of trade on income. Time s...

the main objective of this study is to evaluate the spatial effect on fluctuations of trade based on the spatial panel data econometric method and wavelet smoothing using bilateral trade weighted matrix. the negative spatial dependent are estimated. using data from 34 most-important countries the period of 1980-2010 are investigated through spatial model and maximum likelihood estimation method...

Abstract This article is an empirical attempt to explore the relationship between sanctions (financial and non-financial), oil price shocks and Iran-Russian bilateral trade flows over the period 1991–2014. In contrast to earlier studies in which a gravity model has been estimated through a panel data approach, in this paper the authors apply a gravity model for only two countries and do the es...

This paper presents a sequential non-rigid reconstruction method that recovers the 3D shape and the camera pose of a deforming object from a video sequence and a previous shape model of the object. We take PTAM (Parallel Mapping and Tracking), a state-of-the-art sequential real-time SfM (Structure-from-Motion) engine, and we upgrade it to solve non-rigid reconstruction. Our method provides a go...

Abstract Introduction: Chronic heterogeneous stress may be better for evaluation of the effect of chronic stress situations on the nociceptive behaviour. The present study investigated the effects of chronic heterogeneous sequential stress on thermal-induced nociception and formalin induced pain behavior in rats. Methods: In the present study, adult rats (220-300 g) were used. Animals were ...

Any viable model of serial reaction time (SRT) sequence learning needs to be able to capture the relative extents to which participants learn different SRT sub-sequences. However, previous attempts to empirically establish a relative pattern of this sort have failed to fully control for ‘sequential-effects’, or have not satisfactorily ruled-out the influence of speed-accuracy trade-off. In this...
