Revealed Comparative Advantage (RCA) indices aid in identification of the sectors in which countries reveal comparative advantage or disadvantage. Apart from serving such a dichotomous measure, the RCA indices are frequently employed as cardinal or ordinal measures over time. Application of the indices for comparative analyses calls attention towards the distributions of RCA indices, which must reasonably be stable over time, sectors and countries. Stability of index distributions facilitates the usage of indices as cardinal or ordinal measures over time. The present paper therefore analyses the empirical distributions of RCA indices to determine their suitability. However, such an analysis would be incomplete if the implications for RCA indices due to growing significance of global supply chains are not recognized. Hence apart from analyzing the distributions of gross trade based RCA indices, the distributions of domestic value-added in export based indices are also examined, and the differences are noted. Similar extensive analyses on the distributions of RCA indices are lacking in the literature. In this sense, the present paper makes an important contribution to the existing literature on RCA indices.
Intraday data for weekly options are investigated for behavioral biases implied in prospect theory (PT) and cumulative prospect theory (CPT). The results generally support both theories, with losers (winners) observed to be relatively risk-seeking (averse). On aggregate, losers (winners) overprice (underprice) their contracts and overweight (underweight) the probability of winning. Additionally, the volatility smirk observed in equity options is dampened by PT/CPT biases. The price distortions are time sensitive, especially for losing traders. Losers hold out by transacting later in the day and closer to expiration than their baseline counterparts. This betting-time effect is absent among winners. 相似文献
The effects of media, product and advertising strategy variables on consumers' thoughts and feelings are investigated. Both direct and indirect paths from the advertising variables to ad persuasiveness measures are also analysed with the indirect paths leading through affective and cognitive responses. Two hundred and forty television and magazine ads are analysed with respect to advertising variables, affect, cognition and ad persuasiveness. Results indicate that advertising variables are indirectly linked to ad persuasiveness with the indirect path occurring through affective and cognitive responses. 相似文献
Low‐wage work is of growing significance in the UK. This article tests the model of the low‐skills equilibrium (LSE) through a study of 27 small firms in a sector, food manufacturing, widely identified as being in an LSE. Three hypotheses are tested. (1) There will be a single, fixed equilibrium. We find more variety, reflecting the specific circumstances of firms. (2) An equilibrium is sustained by weak support institutions and a product market dominated by low value‐added goods. The expectation about institutions is supported, but the product market permitted some, albeit weak, opportunities to escape the LSE. (3) Skills will be low, and workplace regimes will be characterised by work intensification. Some firms were developing employee skills. Work intensification was rare, reflecting the absence of Taylorisation and the importance of face‐to‐face relationships. Overall, some firms had the will to escape the LSE, but weak institutional support and a ready supply of labour substantially reduced the incentives to do so. 相似文献
