Using Turkish industry-level data from 1983 to 1990, we find that politically organized industries receive both higher protection and promotion than unorganized ones. Tariff rates are decreasing (increasing) in the import-penetration ratio and the absolute value of the import-demandelasticity for organized (unorganized) industries. Subsidy rates are decreasing (increasing) in the output-supply elasticity for organized (unorganized) industries. The results are consistent with the predictions of the Grossman–Helpman model and its extension in this paper. The mix of protection and promotion is inversely related to the ratio of their respective marginal deadweight cost measures.  相似文献

While there is a plethora of studies segmenting the lucrative tourism market, limited attention has been given to identifying potential segments of local residents based on their image of the place they live in as a tourist destination. This study aims to address this gap by (a) clustering local residents of a tourist destination based on their images of that place; and (b) identifying whether those image-based resident groups share similar/different levels of place attachment and intentions toward tourism (support for tourism, intention to recommend it to others). Analysis was based on a sample of 368 residents of Eilat, Israel. The findings suggest the presence of three resident groups with different images of Eilat – called Nature Aesthete, Appreciator, and Critical – and provide support that these groups exhibit dissimilar levels of attachment and intentions/behavior toward tourism. The Appreciator (residents with the most favorable image) were reported exhibiting higher levels of place attachment, support for tourism and were more likely to recommend their place to others as a tourist destination than the Critical (residents with the least favorable image). The implications of these findings to tourism theory and practice are discussed.  相似文献

This study tests the performance of contrarian (value) strategies in the Athens Stock Exchange (ASE) in a recent period of time (2003–8) on the basis of the price to earnings ratios, dividend yields, firm size (market value), market to book ratios, financial leverage ratios, and market beta. Apart from the univariate portfolio analysis, we implement a novel panel data analysis based on the procedure suggested by Pesaran (2004, Econometrica 74:967–1012, 2006) that provides a valid estimation and inference under cross sectional dependence. Our portfolio analysis results highlight for investors in the ASE the superiority of value strategies formed on the basis of stocks with low price-to-earnings, high dividend yield ratios, and low market-to-book ratios. Our panel data analysis results depend on whether or not we correct for the problem of cross-sectional correlation in the regression residuals as suggested by Pesaran’s (Econometrica 74:967–1012, 2006) method. When we correct for this problem, we obtain evidence which support only a negative association between annual stock returns and market-to-book ratios. This may imply to investors that an adoption of a value strategy based on the market-to-book ratio may constitute a safer option compared with the other two alternatives suggested by the portfolio analysis results.  相似文献

Agriculture has played a central role in Africa's long‐term economic development. Previous research has argued that the low productivity of African economies has posed significant challenges to African efforts to produce an agricultural surplus or to develop commercial agriculture. Low agricultural productivity has also served as a key explanation for the transatlantic slave trade, on the basis that it was more profitable to export humans overseas than to grow and export produce. However, the field has suffered from a lack of comparable empirical evidence. This article contributes to this field by presenting quantitative data on historical land and labour productivity in Africa, from a case study of the agricultural productivity of Senegambia in the early nineteenth century. Focusing on five key crops, our results suggest that both land and labour productivity was lower in Senegambia than it was in all other parts of the world for which we have found comparable data. This article thus lends support to claims that stress ecological factors as one of the main determinants of Africa's historical development.  相似文献

Brands take advantage of technology, social media and constant connectivity to foster organic consumer engagement and interactions towards co-creating personalised customer service. Real-time service offers dynamic engagement with connected consumers. Brands in tourism and hospitality use technology to dynamically enhance consumer experience through co-creation. The integration of real-time consumer intelligence, dynamic big data mining, artificial intelligence, and contextualisation can transform service co-creation by mobilising recourses in the ecosystem. Nowness service emerges by dynamically engaging consumers in experience cocreation in real time. It has five interconnected characteristics that revolutionise the tourism and hospitality, namely: real-time, co-creation, data-driven, consumer-centric and experience co-creation.  相似文献

This paper proves existence of a subgame perfect equilibrium in Hotelling's original (unidimensional city, linear transportation costs, uniform distribution of the consumers, two firms with identical and constant marginal cost, perfectly inelastic demand) location–price game such that in the location subgame the location choices of the firms are pure and identical. The result can be extended to variations of the original setup (multidimensional city, nonlinear transportation costs, nonuniform distribution of consumers, many firms with identical and constant marginal costs, two or more firms with nonidentical but constant marginal costs).  相似文献

The purpose of the paper is to examine the nature of Greek regional unemployment. The paper contributes to the literature assessing the stochastic properties of Greek unemployment rate in the context of the Greek regions by relying on various univariate and panel unit root tests. In particular, recently developed and more powerful panel unit-root tests that control for structural breaks, heterogeneity and cross-sectional dependence in the panel are employed. The results show that in all cases, after taking into account the fact that regional unemployment rates in Greece are subject to a structural break, the null hypothesis of a unit root is not rejected, indicating that the Greek regional unemployment series are non-stationary with the presence of a structural break.  相似文献

Recent evidence on the “fertility rebound” offers credence to the idea that, from the onset of early industrialization to the present day, the dynamics of fertility can be represented by an N-shaped curve. An overlapping generations model with parental investment in human capital can account for these observed movements in fertility rates during the different stages of demographic change. A demographic transition with declining fertility emerges at the intermediate stage, when parents engage on a child quantity–quality trade-off. At later stages, however, the process of economic growth generates sufficient resources so that households can rear more children while still providing the desirable amount of education investment per child.  相似文献

Several studies have attempted to deduce the determinants of sovereign bond ratings. In this study, Extreme Bounds Analysis is applied to approximately 30 factors proposed by the literature in order to assess their robustness with a focus on the relative importance that economic and political variables receive in the shaping of the ratings. We find that policies that constrain the public sector are among the most robust. Variables such as rule of law, openness to economic flows, central bank independence, and market friendly policies are found to be more robustly correlated with the ratings than foreign reserves, fiscal deficit, sovereign bond yields, and economic growth.  相似文献
